Tracy Sfropes, Jeff Flenniken and Dennis Gallegos Gallegos & Associates 5671 Palmer Way, Suite A Carisbad, Califomia 92010 DATE: SOURCE OF COPIES: August 2005 South Coastal Information Center San Diego State University 4283 El Cajon Boulevard, Suite 250 San Diego, CaUfomia 92105 ABSTRACT: This report provides the results of the Carlsbad Municipal Golf Course Data Recovery Program for prehistoric site CA-SDI-8694, and Indexing and Preservation Study for CA- SDI-8303 and CA-SDI-8797 Locus C conducted by Gallegos & Associates. The work was conducted to adequately address mitigation of impacts resulting from the development of the Carlsbad Municipal Golf Course. Mitigation was achieved through the completion of the data recovery program for CA-SDI-8694, and avoidance and capping for CA-SDI-8303 and CA-SDI-8797 Locus C. Prior to avoidance and capping, both CA-SDI-8303 and CA-SDI-8797 Locus C were "sampled using six Ixl-m excavation units per site to provide an index sample representing the archaeological deposit being capped and preserved. Sites CA-SDI-8303, CA-SDI-8694, and CA-SDI-8797 Locus C are located within the City of Carlsbad. The data recovery program for CA-SDI-8694 provided for a 2 to 5 percent phased excavation of the primary site area (3,000 sq. m). This program included excavation of 1x1-m sample units, block excavations, feature excavation, analysis of artifacts and ecofacts, radiocarbon dating, and will provide monitoring during construction grading. The research orientation for.this study focused on chronology, lithic technology, settlement and subsistence sfrategy, environmental setting, and frade and fravel. The index sample included the excavation of six 1x1-m units at both CA- SDI-8303 and CA-SDI-8797 Locus C. All artifacts and ecofacts recovered were washed, analyzed, and special studies for lithic, shell, bone, radiocarbon dating, obsidian sourcing, ceramic and residue analyses were completed. PJ. 4-04 August 2005 The portion of sites CA-SDI-8303 and CA-SDI-8797 Locus C within the Open Space Easements, will be capped using one inch of clean sand, and a minimum of six inches of clean fill soil. Shallow-rooted plants will be used in the Open Space Easements. Water lines and other utilities will need to be placed outside of the Open Space Easements or within the fill soil. As CA-SDI-8694 cannot be avoided of development impacts, mitigation of impacts has been achieved through the completion and acceptance of this data recovery program. The purpose of the data recovery program for CA-SDI-8694 was to adequately address mitigation of impacts through the completion of the excavation of forty-four Ixl-m units, artifact cataloguing, data analysis, and special studies. In all, this work produced 4 bifaces, 5 cores, 1 piece of tested raw material, 8 nodule tools, 4 utilized flake tools, 4 steep-edged unifacial tools (SEUTs or adzes), 10 flakes from SEUTs, 2,367 debitage, 1 hammerstone, 22 battered implements, 19 flakes from battered implements, 61 manos/mano fragments, 6 metates/metate fragments, 18 ground stone fragments, 1 shaped stone, 260 ceramic fragments, 1 Olivella sp. shell bead, 2 bone awls, 1 bone fishing toggle, 1 bone bead, and 1 possible otolith pendant. Faunal material recovered includes 76,492.08 g of shell, 4 otoliths, and 167.9 g of bone. Disturbance from construction, agricultural activities, and bioturbation was noted in all units. The range of artifacts at CA-SDI-8694 indicates a habitation/village site occupied at a minimum during the spring and summer seasons (based on otolith analysis). Flake production from local cobbles, suggests flake tool use. Most likely, these tools were, manufactured and used at the site. Hunting activities may have occurred near this site as indicated by the recovery of two projectile points. The presence of 85 ground stone tools, and 21 battered implements represents preparation of plant foods through pounding and/or grinding. The presence of shellfish remains, and small to large mammal bone demonstrates the range of foods collected, hunted, and processed. In addition, the large number of fish remains suggests a range of maritime activities performed by the inhabitants of CA-SDI-8694. Faunal analysis identified coyote, black-tailed jackrabbit, mule deer, Califomia groimd squirrel, desert cottontail, bmsh rabbit, Botta's gopher, soupfin shark, white croaker, bat ray, Califomia halibut, shovelnose guitarfish, spotfin croaker. Pacific bonito, Califomia sheephead and albacore. This suggests that a range of hunting, fishing, and collecting activities occurred at the site. Analysis of the 76,492.08 g of shell identified the majority of shellfish species as Chione sp. {l\.l>Vo),Argopecten sp. (19.4%), Ostrea lurida{l .2%), and Polinices (0.9%). This collection indicates that the site's inhabitants likely exploited the nearest lagoon habitat (Agua Hedionda Lagoon), and occasionally visited other open coast shoreline areas. The presence of Obsidian Butte obsidian and various cherts suggests possible movement or contact with nearby desert locations, and contact with the inhabitants of the southem Orange County region. However, the majority of lithics used for tool manufacture was locally procured. Ceramic analysis identified the pottery samples as Tizon Brown Ware (mountain ware), Salton Brown Ware (desert ware), and Lower Colorado Buff Ware. PJ. 4-04 xi August 2005 Radiocarbon dating of four shell samples places site occupation primarily during the Early Period (Middle Holocene) circa 5,160 to 7,500 years ago. In addition. Late Period reoccupation is supported by two radiocarbon dates identifying occupation from AD 1000 to AD 1910. These dates are additionally supported by the presence of one Cottonwood Triangular arrow point and ceramics. As demonstrated by the dates recovered and the shell and artifact assemblage, CA-SDI-8694 is a multi-component site with both Early and Late Period occupations. The Indexing and Preservation Study for CA-SDI-8303 included field excavation of six Ixl-m units, artifact cataloguing, data analysis, and special studies. The purpose of the Indexing and Preservation Study was to provide an index sample representing the deposit to be capped and preserved. In all, the Indexing and Preservation Study at CA-SDI-8303 produced 6 bifaces, 9 arrow points, 1 biface preform, 1 flake blank, 10 battered implements, 18 flakes from battered implements, 3 steep-edged unifacial tools (SEUTs), 2 rejuvenation flakes from SEUTs, 6 flake tools, 1 flake knife, 3 cores, 3,887 debitage, I nodule tool, 6 ground stone fragments, 19 manos/mano fragments, 5 metates/metate fragments, 1 polished stone fragment, 449 ceramic fragments, 12 Olivella sp. shell beads, 7 shell disc beads, 1 Cypraea spadicea Swainson (Chestnut Cowry) shell, 1 bone bead, 2 glass frade beads, 1 quartz crystal, 1 fragment of pitch, 2 otoliths, 2 bpne tools, 465.4 g of bone, and 32,838.1 g of shell. Disturbance from agricultural activities, bioturbation, and geologic activities was noted in all units. It is probable that CA-SDI-8303 maintains gOod site integrity. The range of artifacts at CA-SDI-8303 primarily indicates a Late Period habitation/village site occupied at a minimum during the spring and summer seasons (based On availability of plants, animals, and otolith analysis). Flake production from local cobbles, suggests flake tool use. Most likely, these tools were manufactured and used at the site. Hunting activities may have occurred near this site as indicated by the recovery of nine projectile points. The presence of 30 ground stone tools, and 11 battered implements identifies preparation of plant foods through pounding and/or grinding. The presence of shellfish and fish remains, and small to large mammal bone demonsfrates the wide range of foods collected, hunted, and processed. In addition, the diverse fish remains suggest a range of maritime activities performed by the inhabitants of CA-SDI- 8303. Faunal analysis identified black-tailed jackrabbit, desert cottontail rabbit, brash rabbit, mule deer, Califomia quail, soupfin shark, white croaker, bat ray, Califomia halibut, shovelnose guitarfish, spotfin croaker. Pacific bonito. Pacific sardine, Califomia sheephead, and albacore. This collection suggests that a range of hunting and fishing activities occurred at the site. Analysis of the 33,220 g of shell identifies the majority of shellfish species as Donax gouldii (71.6%), Chione sp. (24.8%) and Argopecten sp. (2.7%). This collection indicates a primary exploitation focus on sandy beach habitats by the inhabitants of CA-SDI-8303, with minimal evidence of exploitation of bay/lagoori/estuary habitats. PJ. 4-04 xii August 2005 Prehistoric evidence of trade and travel was identified through the sourcing of obsidian to Obsidian Butte in the Imperial Valley, approximately 100 miles east^northeast of CA- SDI-8303. An additional obsidian specimen provided trace element concentrations geochemically placing its volcanic glass origin to the Coso Volcanic Fields located in Kem County, Califomia. However, the majority of lithics used for tools were manufactured from local materials. Ceramic analysis identified the pottery samples as Tizon Brown Ware (mountain ware), and Lower Colorado Buff Ware (desert ware). The radiocarbon dating of four shell samples and the presence of glass frade beads place the occupation of site CA-SDI-8303 primarily during the Late Period from circa AD 980 to historic contact, with minor evidence of an earlier occupation circa 4,600 years ago. The Indexing and Preservation Study for CA-SDI-8797 Locus C included excavation of six 1x1-m imits, artifact cataloguing, data analysis, and special studies. The purpose of the Indexing and Preservation Study was to provide an index sample representing the archaeological deposit to be capped and preserved. The fieldwork resulted in the collection of 337 debitage, 2 cores, 1 flake tool, 1 steep-edged unifacial tool (SEUT), 17 flakes from SEUTs, 2 battered implements, 4 manos, 1 ground stone fragment, and 1 polished stone. Faunal material recovered includes 8.4 g of bone and 2,353.4 g of shell. Disturbance from constmction, agricultural activities, and bioturbation was noted in all units. The range of artifacts at CA-SDI-8797 Locus C indicates a habitation site primarily occupied during the Early Period (Middle to Late Holocene). The primary flintknapping activity was nodule core reduction; and, the predominant aspect of nodule core reduction was the production of a few very late stage flake blanks, most likely for unmodified flake tools. The presence of five groimd stone tools, and two battered implements implies preparation of plant foods through pounding and/or grinding. The presence of shellfish remains, and small to large mammal bone demonstrates the range of foods collected, hunted, and processed. Faunal analysis identified primarily Sylvilagus audubonii, and other small mammals. Analysis of the 2,353.4 g of shell recovered identifies the majority of shellfish species as Chione sp., Argopecten sp., Ostrea lurida, Polinices sp., and Astrea undosa, indicating that the inhabitants primarily exploited the nearest lagoon habitat (Agua Hedionda Lagoon), and occasionally visited the open coast shoreline area. Evidence for prehistoric trade and travel was identified through the analysis of the lithic materials. For the most part, tools were manufactured from local lithic materials, however, non-local lithic materials were minimally used. These materials include chert (traded from either the north or east), Monterey chert (fraded from the north), and Piedra de Lumbre chert (fraded from the Camp Pendleton area). The radiocarbon dating of four shell samples suggests that the site was occupied from the Middle to Late Holocene, with the primary site occupation occurring circa 5,000 years ago, and the most recent occupation occurring within the past 1,000 years. PJ. 4-04 xiii August 2005 All artifacts collected as a result of this study will be curated at the San Diego Archaeological Center, or with the Luiseno Native Americans (i.e. San Luis Rey Band of Mission Indians). For the direct impact area of CA-SDI-8694, mitigation of impacts has been achieved through the completion ofthe data recovery program. Both CA-SDI-8303 and CA-SDI- 8797 Locus C will be protected within Open Space Easements, and capped. Capping using a minimum of one-inch of sand and six to twelve inches of fill, and planting of shallow-rooted native plants is recommended. Utilities (i.e., water, gas, and sewer) and deep-rooted plants are to be placed outside ofthe Open Space Easements. Given the potential for finding human remains, monitoring during constmction grading by an archaeologist and a Native American shall be conducted. Prior to issuance of the grading permit, the city planner shall verify that the requirements for archaeological monitoring have been noted on the appropriate constraction documents.

Mitigation will be achieved through the completion of data recovery for CA-SDI-8694, and avoidance and capping for CA-SDI-8303 and CA-SDI-8797 Locus C. Prior to avoidance and capping, both CA-SDI-8303 and CA-SDI-8797 Locus C were sampled using six Ixl-m excavation units per site to provide an index sample representing the deposit being capped and preserved. The portion of sites CA-SDI-8303 and CA-SDI-8797 Locus C within Open Space Easements, will be capped using one inch of clean sand, and a minimum of six inches of clean fill soil. Shallow-rooted plants will be used in the Open Space Easements. Water lines and other utilities will need to be placed outside of the Open Space Easements or within the fill soil. As CA-SDI-8694 cannot be avoided of development impacts, mitigation of impacts was achieved through the completion of a data recovery program. Sites CA-SDI-8303, CA-SDI-8694, and CA-SDI-8797 Locus C are located within the City of Carlsbad (Figures 1-1 and 1-2). The data recovery program for CA-SDI-8694 provided a 2 to 5 percent phased excavation ofthe primary site area (3,000 sq. m). This program included excavation of 1x1-m sample units, block excavation, analysis of artifacts and ecofacts, radiocarbon dating, and monitoring during constraction grading. The research orientation for this study will focus on chronology, lithic technology, settlement and subsistence sfrategy, environmental setting, and frade and fravel. The index sample will include the excavation of six Ixl-m units at both CA-SDI-8303 and CA-SDI-8797 Locus C. All artifacts and ecofacts recovered will be washed, analyzed.

The lagoon habitat provided rich and varied food resources for prehistoric populations. These resources include shellfish, fish, plants, and small, medium, and large mammals. The vegetation for the Carlsbad Municipal Golf Course includes cultivated lands and native Coastal Sage Scrab. The ridgelines. are Pleistocene marine terraces containing cobble deposits that were exploited by Native Americans throughout prehistory for a range of tools such as cores (for making a wide range of flake based tools), percussion tools (i.e., hammers, battering implements), milling tools, and firehearths. Soil within the study area is sandy loam underlain by a sandstone deposit. 1.3 BACKGROUND - PREIDSTORY The body of current research of prehistoric occupation in San Diego County recognizes the existence of at least two major cultural fraditions, discussed here as Early Period/Archaic and Late Period, based upon general economic frends and material PJ. 4-04 1-4 August 2005 cultiire. Within San Diego County, the Early Period/Archaic spans from roughly 9,500 to 1,300 years ago, and the Late Period includes from 1,300 years ago to historic contact. The Historic Period covers the time from Spanish contact to the present (Table 1-1). 1.3.1 Early Period/Archaic The Eariy Period/Archaic, for this discussion, includes the San Dieguito and La Jolla complexes, which are poorly defined, as. are the interrelationships between contemporaneous inland, desert, and coastal assemblages (Gallegos 1987). Initially believed to represent big game hunters, the San Dieguito Complex is better typified as a hunting and gathering society. These people had a relatively diverse and non-specialized economy wherein relatively mobile bands accessed and used a wide range of plant, animal, and lithic resources. Movement of early groups into San Diego County may have been spurred by the gradual desiccation of the vast pluvial lake system that dominated inland basins and valleys during the last altithermal period. This hypothesis is supported by the similarity between Great Basin assemblages and those of early Holocene Archaic sites in San Diego County. Several researchers have recognized the regional similarity of artifacts and grouped these contemporaneous complexes under the nomenclature of either the Westem Pluvial Lakes Tradition or the Westem Lithic Co-Tradition (Rogers 1939; Warren 1967; Davis et al. 1969; Bedwell 1970; and Moratto 1984). The origin of coastal populations and subsequent interaction between the coastal population and Great Basin desert groups is a subject of some debate (Gallegos 1987). Whatever their origin, the first occupants immediately exploited the coastal and inland resources of plants, animals, shellfish, and fish (Moriarty 1967; Kaldenberg 1982; Gallegos 1991; and Kyle et al. 1998). The development of a generalized economic system indicates that the inhabitants of the San Dieguito Complex and related groups can be placed within the general Early Period/Archaic pattem. Early Period/Archaic cultures occur within North America at slightly different times in different areas, but are generally correlated with local economic specialization growing out of the eariier Paleo-Indian Tradition (Willig et al. PJ. 4-04 1-5 August 2005 Tablel-1 Terminology for Culture History in the San Diego Area (Gallegos 2002) ® s S H O •a o .mm U <u Years Before Present Other Names Diagnostic Cultural Material a <U S ^ ffl T3 JS u :< -o o .mm PH Present 1,300 Historic Late Prehistoric Yuman Cuyamaca Complex San Luis Rey I, II 2,000 3,000 /K 4,000 5,000 6,000 7,000 8,000 9,000 10,000 Pauma Complex Encinitas Tradition La Jolla Complex Bow and arrow, small triangular and side-notched points, cremations, fish hooks, ceramics Obsidian Butte obsidian. w.„ Stone bowls, triangular points fishing gorges, burials.

Spear, crescents, lanceolate and leaf-shaped points, leaf-shaped knives, Casa Diablo and Coso Obsidian, burials. San Dieguito Tradition/Complex 1988). Early Period/Archaic cultures are often represented by more diverse artifact assemblages, and more complex regional variation than Paleo-Indiah tiraditions. This is generally thought to have resulted from the gradual shift away from a herd-based hunting focus to a more diverse and area-specific economy. The eariiest Eariy Period/Archaic sites are found near coastal lagoons and river valleys of San Diego County. These sites are the Harris site (CA-SDI-149), the Agua Hedionda sites (CA-SDI-210/UCLJ-M-15 and CA-SDI-10695), Rancho Park North (CA-SDI-4392/SDM-W-49), and Remington Hills (CA-SDI-11079), all dating from 9,500 to 8,500 years ago. The north San Diego County coastal lagoons supported large populations circa 6,000 years ago, as shown by the numerous radiocarbon-dated sites adjacent to these lagoons. After 3,000 years ago, there is a general absence of archaeological sites in north San Diego County to circa 1,500 years ago. This reduction in the number of archaeological sites can be attributed to the siltation of coastal lagoons and the depletion of shellfish and other lagoon resources (Warren and Pavesic 1963; Miller 1966; Gallegos 1985). Archaeological sites dated to circa 2,000 years ago are found closer to San Diego Bay, where shellfish were still abundant, and may well represent what can be considered the end of the La Jolla Complex (Gallegos and Kyle 1998). The La Jolla and Pauma complexes, identified as following the San Dieguito Complex, may simply represent seasonal or geographic variations of the somewhat older and more general San Dieguito Complex. Inland La Jolla Complex occupation sites have been reported in fransverse valleys and sheltered canyons (Trae 1959; Warren et al. 1961; Meighan 1954). These non-coastal sites were termed "Pauma Complex" by Trae (1959), Warren et al. (1961), and Meighan (1954). Pauma Complex sites by definition have a predominance of grinding implements such as manos and metates, a lack of shellfish remains, greater tool variety, a greater expression of a more sedentary occupation, and a sfronger emphasis on both gathering and hunting (Trae 1959; Warren et al. 1961; Meighan 1954). PJ. 4-04 1-7 August 2005 Early Period/Archaic site types from 9,500 to 1,300 years ago within San Diego County include coastal habitation sites, inland hunting and milling camps, and quarry sites. Material cultural assemblages during this long period are remarkably similar in many respects. These deposits may well represent a process of relative terrestrial economic stability, and presumably slow cultural change. Though various culture fraits developed or disappeared during the span of 9,500 to 1,300 years ago, there is a clear pattem of cultural continuity during this period. 1.3.2 Late Period During the Late Period (circa 1,300 years ago to historic contact), a material culture pattem emerged in the archaeological record similar to that of the Native Americans documented by ethnohistoric researchers. The economic pattem during this period appears to be one of more intensive, and efficient exploitation of local resources. The prosperity of these highly-refined economic pattems is well evidenced by the numerous Kumeyaay/Dieguerio and Luiseiio habitation sites scattered throughout San Diego County. This increase in Late Period site density probably reflects better preservation of the. more recent archaeological record, and a gradual population increase within the region. Artifacts and cultural behaviors reflecting this Late Period pattem include small projectile points, pottery, the establishment of semi-permanent or permanent seasonal village sites, the proliferation of acom milling sites in the uplands, the appearance of obsidian from Obsidian Butte, and interment by cremation. Many of the Late Period cultural, pattems in southem Califomia were shared with groups along the eastem periphery of the region. Even in the most recent periods, the Native Americans of southem Califomia incorporated many elements of their neighbors' cultures into their own culture. This transferring and melding of cultural fraits between neighboring groups makes it difficult to identify associations of archaeological deposits with particular ethnographically-known cultures. This is particularly tme of groups within San Diego County. Although significant differences exist between Luiseno and Kumeyaay/Dieguefio cultures, including linguistic stock, the long interaction of these groups during the Late Period resulted in the exchange of many social pattems. PJ. 4-04 1-8 August 2005 I I I I I I I I i I I I I i I I I I I Archaeologists must rely heavily on ethnographic accounts of group boundaries as recorded during the historic period, although it is not known how long these boundaries had been in place, or the validity of these boundaries as reported and recorded. Florence Shipek, Ph.D. (1993) identifies the northem and southem Kumeyaay/Dieguefio tiibal boundary as: In 1769, Kumeyaay national territory starting at the coast about 100 miles south of the Mexican border (below Santo Tomas), thence north to the coast at the drainage divide south ofthe San Luis Rey River including its tributaries. Using the U.S. Geological Survey topographic maps, the boundary with the Luiseno then follows that divide inland. The boundary continues on the divide separating Valley Center from Escondido and then up along Bear Ridge to the 2240 contour line and then north across the divide between Valley Center and Woods Valley up to the 1880 Ft. peak, then curving around east along the divide above Woods Valley... Following Shipek's (1993) definition, the project area falls near the boundary between the territories ofthe Kumeyaay/Dieguefio and Luisefio Native Americans. As a result of contact with Spanish, Mexican, and American settlers. Native American populations were decimated by resettlement and disease. Presently, Native Americans are found throughout San Diego County, especially within the 18 San Diego County reservations. Further readings on Kumeyaay/Dieguefio and Luiseno Native Americans include Almstedt (1974); Barrows (1900); Bean (1972); Bean and Saubel (1972); Burrus (1967) Cuero (1968); Dracker (1937); Dubois (1908); Gifford (1918); Harrington (1978) Hedges (1986); Heizer and Almquist (1971); Heizer and Whipple (1957); Hooper (1920) Keneally (1965); Kroeber (1925); Langdon (1970); Luomala (1978); Merrill (1973) Pourade (1960); Priestley (1937); Robinson (1969); Rudkin (1956); Shipek (1977, 1978, 1980, 1986 a and b, 1987, 1988, 1989 a and b, 1991, 1993); Sparkman (1908); Spicer (1962); Spier (1923); Sfrong (1929); Tibesar (1955); Underbill (1941); White (1963); Wolcott (1929); and Woodward (1934). 1.3.3 Protohistoric Period The Hispanic intinsion and colonization (1769-1822) within Native American southem Califomia, affected the coastal fribes and peoples living in well-fraveled river valleys. PJ. 4-04 1-9 August 2005 The Mexican Period (1822-1848) saw continued displacement ofthe native populations by expansion of the land grant program, and development of extensive ranchos. The gold rash of 1849, and the concomitant granting of Califomia's statehood in 1850, resulted in an influx of Anglo-Americans and a rapid displacement of the Native Americans, and a deterioration of their culture and lifeways (Bancroft 1886; Kroeber 1925). 1.4 SITE BACKGROUND AND SIGNIFICANCE 1.4.1 CA-SDI-8303 Testing in 1999 (Gallegos et al.) included the excavation of 51 shovel test pits (STPs), and five Ixl-m units (Figure 1-3). This work produced over 1,107 artifacts that included a wide range of tools, beads, a Haliotis sp. (abalone) shell fish hook, ceramics, arrow points, milling tools, 13,730.85 g of shell, and 122.75 g of bone (Table 1-2). Site. CA- SDI-8303 is a major village site, occupied circa 760 to 1,080 years ago. The shell recovered reflects both lagoon and open coast habitat exploitation. Obsidian was also recovered and sourced to Obsidian Butte in the Imperial Valley. Other frade material includes chert, wonderstone, siltstone, and Piedra de Lumbre chert. The high number of artifacts and ecofacts recovered, the diversity of artifactual and ecofactual material, and the potential of this site to address important research questions provide sufficient information to identify CA-SDI-8303 as a significant cultural resource under CEQA and federal criteria. A data recovery program was completed by RECON (Cheever and Berryman 1999) to mitigate Faraday Road constraction impacts (Figure 1-4). The mitigation of impacts for CA-SDI-8303 included the excavation of 27 sq. m of archaeological deposit. RECON reported that the area excavated "...appears to represent a seasonal campsite occupied on a short-term basis" (Cheever and Berryman 1999). In all, 794 debitage, 34 flaked lithic tools, 390 ceramics, 4 shell beads, 8 ground stone tools, 130.6 g of bone, and 40,701.6 g of shell were recovered (Cheever and Berryman 1999). Site CA-SDI-8303 will be index sampled, capped, and avoided of impacts..

This work produced 584 artifacts, 3,477 g of shell, and 33,9 g of bone (Table 1-3). Given the extensive and diverse artifact assemblage present to address research questions, this habitation site, occupied circa 5,000 years ago, is identified as significant under CEQA criteria. As CA-SDI-8694 will be directly impacted by the proposed development, mitigation of impacts will be achieved through the completion of a data recovery program. 1.4.3 CA-SDI-8797 Site CA-SDI-8797 was initially recorded by Malcolm Rogers as SDM-W-116. This site was tested and identified as significant under City of Carlsbad and CEQA criteria (Gallegos and Kyle 1992; Gallegos and Harris 1995; and Gallegos et al. 1999)(Figure 1- 6). Testing conducted at Locus A by Gallegos and Kyle (1992) identified a cultiiral deposit to 80 cm that included the recovery of debitage, cores, ground stone, a scraper, ceramics, a biface fragment, a shell bead, an otolith, modified bone, and shell (Table 1- 4). Testing of site CA-SDI-8797 Locus B (southem portion of CA-SDI-8797) included collection of surface artifacts, and excavation of 21 STPs (Gallegos and Harris 1995). Locus B contained milling tools, bone tools, a shell bead, bone, shell, and depth of deposit to approximately 100 cm. The test excavation of CA-SDI-8797 Locus C identified a rich cultural deposit, and the presence of human remains (Gallegos et. al 1999). This portion of CA-SDI-8797 was radiocarbon dated to circa 5,000 years ago.

The Site Index and Preservation Sttidy for prehistoric sites CA-SDI-8303 and CA-SDI-8797 Locus C were prepared by Gallegos & Associates to provide a sample of the archaeological deposits and long-term protection of the resources through capping ofthe primary site areas of CA-SDI-8303 and CA-SDI-8797 Locus C. The Data Recovery Program for CA-SDI-8694 was conducted to adequately address mitigation of impacts under CEQA and City of Carlsbad requirements. 2.2 RESEARCH QUESTIONS The research orientation, developed for the site indexing and preservation studies and the data recovery program employed regionally and locally specific questions, and identified data needs to approach these questions. A wide range of research questions or topics was possible for sites CA- SDI-8303, CA-SDI-8694, CA-SDI-8797 Locus C. However, five research domains were selected on the basis of previous work, available data to address these questions, and overall contribution to the archaeological record. The specific research questions focused on chronology; lithic technology; subsistence sfrategy; site type and settlement pattem; and, ttade and travel. For the index samples, these research topics will be used to guide the study, however sufficient materials to answer the research questions may not be recovered given the small number of sample units and nature of this study. • Chronology What was the period(s) of use and/or occupation for the sites? Determining the period of occupation of a site or a region can be accomplished by the use of radiocarbon dating and by relative dating. Radiocarbon dating depends on the retrieval of PJ.4-04 2-1 August 2005 materials (i.e., bone, shell, charcoal) amenable to scientific analysis. Radiocarbon dates for north San Diego County range from roughly 10,000 years ago to historic contact. Altematively, relative dating is based on the recovery of specific artifacts that are temporally diagnostic. Temporally diagnostic artifacts recovered in context with associated radiocarbon dates include atlatl-dart points, arrow points, and ceramics. Obsidian sourcing and hydration rind measurements are also relative dating measures, as obsidian absorbs water at slow and somewhat constant rates. Obsidian from sources such as Obsidian Butte in the Imperial Valley was available during the late Holocene, while obsidian from the Coso Range was available throughout the Holocene. In order, to address the research questions posed, temporal placement ofthe site is necessary. Previous work at CA-SDI-8303 and CA-SDI-8694 identified Late Period components as defined by the presence of pottery and small projectile (arrow) points. Sites CA-SDI-8694 and CA-SDI-8797 also contain Early Period components as illusfrated by the radiocarbon dating of shell from these two sites. Data Needs Shell, bone, and charcoal are present at sites CA-SDI-8303, CA-SDI-8797, and CA-SDI-8694. Multiple shell samples from each site were submitted for radiocarbon dating. The testing program also produced small arrows points, ceramics, and obsidian. Shell specie preference or availability may also be used to place sites within a relative order. For example, marine shell can be identified by species to determine shell habitat, and, along with radiocarbon dates, can be used to identify environmental setting and change within the Holocene. Methods of Collection Shell retrieved during the subsurface excavation programs was clearly labeled with provenience (i.e., site, unit, level, date, person collecting the sample, associated feature), and date of recovery, and was submitted to Beta Analytic, Inc. for Accelerator Mass Specfrometry (AMS) radiocarbon dating. AMS results are provided in Sections 3 through 6. Obsidian was separated from other debitage, wrapped in plastic to prevent edge damage, and labeled appropriately. Diagnostic PJ. 4-04 2-2 August 2005 artifacts recovered during surface collection or excavation were placed in resealable plastic bags, labeled, and catalogued. • Lithic Technology How do the assemblages reflect the technological trajectories used by the prehistoric inhabitants? Which lithic reduction strategies were in use and when? Several flake-tool reduction sfrategies have been identified for the southem Califomia coastal region. These include biface reduction, split-nodule core reduction, small blade core reduction, bipolar core reduction, and nodule reduction. The decision to use one or the other of these techniques was dependent on several factors, but the most important factors were the type of material that was worked, the morphology of the parent material, and the intended tool. Some lithic materials, such as Monterey chert and Piedra de Lumbre chert, are more easily worked, and with heat-freatment become some of the best knappable material in the westem United States. Problems exist, however, in the form of the material in its raw state. Piedra de Lumbre chert generally occurs in small pieces, thus it was used extensively in the late Holocene for small arrow points (Pigniolo 1992). This material has been recovered from a site dating to 8,000 years ago (Gallegos 1991). Monterey chert occurs in small cobbles and in layers. For small cobbles, bipolar reduction would be the most efficient method of producing usable flakes. For the layered Monterey chert, biface reduction was the most expedient method of producing tools, as the layers were already thin, and only the outer perimeter needed to be worked (Cooley 1982). Other chert sources in San Diego County need to be identified and the material chemically characterized. Large biface production and reduction requires pieces of material large enough to be reduced, and homogenous enough to produce workable items. Santiago Peak Volcanics found in San Diego County have been used extensively for the production of large tools (i.e., adzes, scrapers, scraper planes, cores, hammerstones) and bifaces (Schroth and Flenniken 1997). The use of quarry material from these formations may be an early to middle Holocene marker, as the larger spear and dart points would have necessitated the use of larger blocks of parent material. PJ. 4-04 2-3 August 2005 Nodule core reduction comprises numerous techniques with specific trajectories such as pyramidal- shaped split-nodule core reduction (used to produce thick, contracting flakes for flake tools), the production of teshoe flakes for large flake tools and nodule core tools wherein the parent material rather than the removed flakes become tools. Cobble layers found in streambeds, across coastal terraces, and along the coast provided materials for these reduction sequences. Ground stone artifacts (i.e., manos, metates, and pestles) occur on sites throughout San Diego County, and especially at habitation sites, milling stations, and temporary camps. To date, little analysis has been conducted regarding ground stone manufacture and use, or change of use through time in the San Diego region. An analysis of debitage and lithic tools from site CA-SDI-10148, located south of the San Diego River near Santee, was completed by Flenniken (Kyle and Gallegos 1993). Flenniken determined that all of the flaked core/cobble tools recovered from the site were used for ground stone manufacture and rejuvenation, and that the debitage was the result of both tool manufacture, and rejuvenation of ground stone grinding surfaces. Analysis of debitage and tools from habitation sites can provide information regarding manufacture, use, and rejuvenation of ground stone. Changes in resources and task-specific uses should be analyzed to determine if ground stone tools were designed for specific tasks, and if technological changes occurred through time as climate and resources changed. Assuming that sufficient quantities of lithic materials will be recovered, the following research hypotheses will be addressed. HO: Specific lithic reduction techniques have changed through time, with large biface reduction and steep-edged unifacial tools dominating during the early and middle Holocene, and small biface reduction and nodule core reduction dominating during the late Holocene. HI: All reduction sfrategies were equally important throughout the Holocene. Studv Topics (a) Which technological reduction sfrategies are present based on the debitage at the site? PJ.4-04 2-4 August 2005 (b) Which reduction sfrategies were used to produce which tools? Were these sfrategies the same or different? (c) Are recovered tools made from local or imported materials? (d) If ground stone tools are present, are the cobble materials local or non-local? (e) Is there evidence that ground stone tools were produced at the site, or were they produced elsewhere and then carried to the site? (f) How do technologies and stages of tool reduction relate to site function and tools recovered at the sites? (g) Can the recovered tool forms be assigned to specific culture groups? Data Needs (a) Collection of a sample of cores and debitage. (b) Detailed analysis of cores and debitage for technological attributes and reduction sequence classification. (c) Identification of the technological attributes and reduction sequences used to produce the tools.. . • Subsistence Strategy, Site Type, and Settlement Pattern What settlement and subsistence patterns can be identifled, and have these patterns changed over time? Did the collection of shellfish change with time? If so, what influenced the changes: environment, populations, technologies, or combinations of these factors? Temporally, how do these sites fit into the overall pattern for San Diego County? That is, what group or culture is being examined in the context of the known culture history, and can period of occupation be differentiated? If a given site is representative of a specialized camp and/or gathering group, what was the site's function, and how does the site relate to other sites: as a base camp, a special-use site, or as an extractive site? How did occupation and use of the sites contribute to seasonal or year-round occupation of the region in general? PJ. 4-04 2-5 August 2005 The most pronounced environmental change for coastal southem Califomia is the rise in sea level that occurred during the early to middle Holocene, and the flooding of coastal valleys and the creation of lagoons associated with this event. Evidence of environmental change in lagoons is based on analysis of core samples combined with radiocarbon dates and radiocarbon dated shellfish samples taken from prehistoric sites near lagoons. Environmental studies using shellfish to explain site patterning, and envirormiental change include Miller (1966), Warren et al. (1961), Warren and Pavesic (1963), Bull and Kaldenberg (1976), Gallegos (1985), and Masters (1988). Circa 3,500 years ago, sea level stabilized, causing an increase in siltation processes that eventually caused degradation of the lagoons during the late Holocene. In confrast to San Diego Bay, the environmental change in north San Diego County was more complex. San Diego Bay formed in the early Holocene and stayed open to the ocean throughout the Holocene (Gallegos and Kyle 1998). As such, some prehistoric sites reflect a changing environment and an absence of lagoonal shellfish and fish, whereas other sites, wherein the inhabitants were dependent upon San Diego Bay, reflect continuity in shellfish and fish exploitation. . Large quantities of shellfish are generally not recovered from inland prehistoric sites. This relative lack of shellfish remains may be the result of poor preservation. Changes in use of shellfish and fish through time may, therefore, be difficult to determine. Environmental changes have also been documented for the coastal region, suggesting climatic drying and accompanying vegetation changes occurring over the past 7,000 years (Davis 1992). Pollen studies suggest that pine trees, oak trees, and grasslands were present during the early and middle Holocene. The Native American occupation of San Diego County during the 10,000-year period of the Holocene is poorly documented. Gallegos (1987) suggests that early and middle Holocene (Early Period/Archaic) sites, identified as inland San Dieguito, Pauma, and coastal La Jolla complex occupations, were occupied by the same cultural group on a seasonal round. Another hypothesis suggests that Native Americans had large village sites occupied year-round with little change in diet (White 1963). True (1970) hypothesizes that Late Period settlement pattems include winter village sites at lower elevations, and summer village sites in the mountains with occupation based on seasonal subsistence. PJ. 4-04 2-6 August 2005 A research goal of San Diego archaeology over the past several decades has been the typing of Late Period archaeological sites into either San Luis Rey (Luisefio) or Cuyamaca (Kumeyaay/Dieguefio) complexes. Archaeologists have suggested that sites typifying the San Luis Rey Complex assemblage were occupied by ancesfral Luisefio, and those of the Cuyamaca Complex by ancesfral Dieguefio (Kumeyaay). These complexes were first divided by Meighan (1954) into north and south manifestations, and were further defined by Trae (1966). True's goals in his 1966 and 1970 work were to provide a basis for professional-quality cultural reconstractions, and detailed comparative studies. His 1966 work focused on an attempt to isolate pattems that coincided with linguistic boundaries in San Diego County. The differences between these complexes were based primarily on the archaeological record defined by Trae in 1970, and atfributed to degree rather than to artifact type. This included the hypothesis that San Luis Rey Complex sites, as compared to Cuyamaca Complex sites, display an inhabitant preference for Cottonwood Triangular points over Desert Side-notched points; and that Cuyamaca Complex sites display an inhabitant preference for Desert Side-notched points. While both San Luis Rey and Cuyamaca complex sites may contain ceramics, Cuyamaca Complex sites generally display more exotic ceramic forms such as multiple vessel types, bow pipes, effigies, and rattles. Milling equipment and steatite are also believed to be more common in Cuyamaca Complex occupations. Trae (1970) states that hearths in Cuyamaca Complex sites are clay lined; cemeteries are distinct from living areas; arid cremations are placed in ceramic ums with offerings and markers. Trae's (1970) specific list for typical features of Cuyamaca Complex (Kumeyaay/Dieguefio) sites are as follows: • Defined cemetery areas apart from living areas. • Use of grave markers. • Cremations placed in ums. • Use of specifically made mortuary offerings such as miniature vessels, shaft sfraighteners, and elaborately made projectile points. • Cultural preference for side-notched projectile points, indicating a desert connection. PJ. 4-04 2-7 August 2005 • Substantial numbers of scrapers, scraper planes, and flaked tools, in contrast to small numbers at San Luis Rey sites at a contemporaneous time. • Emphasis placed on ceramics to include a wide range of forms and several specialized items such as rattles, bow pipes, and effigies. • A well-developed local steatite industry. • A substantially higher frequency of milling stone elements when compared to San Luis Rey. • Clay-lined hearths. Given that sufficient faunal remains are recovered as a result of the data recovery program, the research hypotheses and study topics listed below will be addressed: HO: During the Holocene, the environment of the coastal plain changed through time. The apparent difference in faunal consumption at these sites is a reflection ofthe changing environment of the coastal plain. HI: During the Holocene, the environment of the coastal plain was stable, thus changes in faunal consumption cannot be equated with natural changes. Studv Topics (a) Do the sites contain sufficient information to determine site type, duration of stay, or possible cultural affiliation? (b) Can the sites be placed within a temporal settlement system for contiast with other earlier or later settlement systems? (c) Do the sites represent both Early Period and/or Late Period components, and can environmental change in the faunal assemblage be identified? (d) Do the sites represent specialized food processing localities, or conversely, do they represent campsites wherein a wide range of foods were gathered and processed? (e) On the basis of Trae's (1970) work and artifacts recovered, can the sites be culturally identified as Kumeyaay/Dieguefio or Luiseno occupation sites? PJ. 4-04 2-8 August 2005 Data Needs Data necessary to address the questions of diet and economic strategy includes floral and faunal remains to permit the reconstraction of diet or dietary practices and preferences of the site occupants. The presence of particular species of plants and animals allows for a more complete appraisal of the various environmental niches exploited by the site occupants. Methods for interpreting the data include speciation of the recovered faunal assemblage, with special attention to evidence of butchering or cooking; and the identification of species within preferred habitats, and the placement of these speciated remains within the ecological model to reconstract the habitat(s) exploited by the site occupants. Artifacts recovered from the site can also provide inferential information regarding subsistence exploitation. For example, if plant material is not found, the presence of mortars, manos, and metates provides evidence that floral and faunal material was processed at the site. Immunological studies of residues on tools from the site may provide data relating to both the use of tools and to the resources exploited. On the basis of previous studies, pollen and phytolith preservation may be poor, and as protein residue analysis is a costly procedure, it should be undertaken only when intact subsurface levels and/or features are present. • Trade and Travel To what extent are trade and travel evidenced at the sites? Early travelers and ethnographers noted the presence of Native American trails and trade activities among different cultural groups in the southern California region. The procurement of lithic resources, such as serpentine, chalcedony, chert, jasper, obsidian, and steatite, may identify contact with other cultural groups, as these materials were not available in the local area. Although many other trade items were perishable, what non-perishable archaeological evidence demonstrates trade and/or travel? Several exotic lithic materials (i.e., obsidian, and Piedra de Lumbre chert) have been identified as trade items. Their occurrence at San Diego County sites aids in delineating frade/travel routes. PJ. 4-04 2-9 August 2005 Further research with exotic material found in context will be necessary, to determine the extent of trade, what materials were traded, and if ttade materials and routes changed through time. Generally, if obsidian was present in early and middle Holocene sites in San Diego County, then it was obtained from the Coso Range, located over 300 miles north, in north-centtal California. Obsidian from late Holocene sites is usually sourced to Obsidian Butte in the Imperial Valley. Obsidian was also available from Mexico, and from other sources not presently identified. Other non-local lithic materials that may have come from nearby sources include jasper, chert, and chalcedony. Such material generally occurs at sites as very small retouch flakes, or as finished items, suggesting that the items were procured in a late lithic reduction stage. This behavior suggests, therefore, that the material was likely procured by frade. Had the material been obtained by direct procurement, then the raw material and early stages of tool production would have been present. Sources for these materials, and sites near the sources where the material was worked, need to be identified to fully understand the frade network involved. Neufron activation analysis has been used successfully to source these exotic materials. Steatite sources are present in southem San Diego County, and include a fairly large quarry called the Stonewall Quarry located in Rancho Cuyamaca State Park (Trae 1970). Another known quarry, the Jacumba Valley Quarry, is located near the U.S./Mexico border approximately 95 km (59 miles) from the Pacific Ocean (Polk 1972). Neutron activation has been used successfully to match specific steatite artifacts to specific sources or quarries, and provides valuable information for identifying trade/fravel directions. The shell that occurs in San Diego County sites is evidence of fravel to lagoons or open coast habitats, or of trade with groups occupying those regions. The closest source of shellfish is Agua Hedionda Lagoon located within 1-2 miles of all three of the sites being examined for this study. Research questions for shell include: Did the site occupants travel to the lagoon and/or open shore to acquire shell? Did they obtain Olivella sp. shell and make spire-lopped beads? Were decorative shells from other, non-local areas, such as Olivella sp. shells from the Gulf of Califomia, acquired through trade and/or fravel? PJ. 4-04 2-10 August 2005 If trade materials are recovered as a result of the data recovery program, the research hypotheses and study topics listed below can be addressed: HO: During the early Holocene, trade was long-distance, possibly through trading partners in a down-the-line pattem. Obsidian was imported, and was primarily obtained from the Coso Range located in east-central Califomia (Hughes and Trae 1987). During the middle Holocene, ttade consisted of mutual bartering with local neighbors, and Piedra de Lumbre chert from north coastal San Diego was a preferred lithic import. During the late Holocene, trade was practically non-existent, however some trade materials, such as obsidian from Obsidian Butte, are present in the artifactual assemblages. HI: Trading for preferred lithic material was a common practice throughout the Holocene with no change in distance or direction. Studv Topics (a) Is there evidence of frade and/or ttavel? (b) What was the nature of cultural contact: continuous, sporadic, or limited? (c) What are the inferred routes of frade? (d) What econornic needs, if any, were met through contact and frade? Data Needs (a) Recovery and analysis of an adequate sample of cultural material that includes frade goods (i.e., obsidian, Piedra del Lumbre chert, Monterey chert, desert lithic material, steatite and beads). (b) Identification of the sources of trade items. In addition, it should be noted that ceramics may provide an important tool in defining cultural boundaries, and the presence or absence of trade/travel. Beginning on the west, the boundary separating Kumeyaay and Luisefio territories is identified as between Agua Hedionda Lagoon and Batiquitos Lagoon and extending to just south of Escondido, and then continuing to the northeast to the Cupefio territory. Ceramic sourcing may provide clues to the classifying of Late Period sites to PJ. 4-04 2-11 August 2005 Kumeyaay or Luisefio cultural occupation. It is anticipated that a minimum of 90 ceramic fragments, representing up to three pottery types, will be recovered for analysis. 2.3 RESEARCH PRIORITIES Many of the research questions overlap, as they address environmental setting, and prehistoric occupation. Research priorities for this study are: chronology, lithic technology, subsistence strategy, and trade and fravel. 2.4 DATA NEEDS Sites CA-SDI-8303, CA-SDI-8797, and CA-SDI-8694 contain a range of artifacts and ecofacts, including shell, bone, flaked lithic tools, ground stone, and non-local obsidian and chert, to address the research questions posed. Artifacts such as non-local obsidian and chert will be used to address the question of trade and fravel. The presence of shell will be valuable in providing material for dating associated tools or features. Radiocarbon dates for the site, and association with artifacts and features will greatly assist in addressing questions conceming chronology and settlement pattem. Faunal remains (i.e., shell, fish bone, and mammal bone) will be collected, speciated, and weighed to provide data to address both diet and seasonality. Artifacts and features will be analyzed with respect to chronology. Shellfish will be analyzed to identify range and quantity of species, as well as paleoenvironmental lagoon shellfish habitat. This analysis will assist in understanding environmental setting and site function. 2.5 LABORATORY METHODS To address the research questions posed, a number of diagnostic tools, shell samples, and hearth features need to be recovered and analyzed. Previous work at each site demonstrates the presence of faunal remains including shellfish and small manmials, as well as milling tools and non-local lithic material. Cores, tools, and debitage are also present to provide the information necessary to address questions of material preference and tool technology. PJ.4-04 2-12 August 2005 Gallegos & Associates' standard system of cleaning, cataloging, and analyzing cultiaral remains was used for artifacts recovered during this study. These procedures include cleaning and separating artifacts and ecofacts by material class for each unit level prior to cataloging. Each item, or group of items, was counted, weighed and/or measured, and given a consecutive catalogue number marked directly on the artifact or on an attached label. Additionally, each item was analyzed for specific characteristics peculiar to each material class. All catalogued items were divided into typological categories, and placed within appropriately labeled boxes for interim storage at Gallegos & Associates' cultural resource laboratory. All artifacts and ecofacts collected were tteated using accepted and appropriate archaeological procedures. Initial laboratory work included washing and/or brashing artifacts, and cataloging. Artifacts were sorted into classes, such as bifaces, cores, bone tools, beads, milling tools, and flakes. Cataloging provides basic data such as count, measurement, weight, material type, condition, and provenience. The catalogue also offers information as to horizontal and vertical distribution of cultural material. Specialized studies were conducted after the initial sorting and cataloging. The number and type of specialized studies completed for this project was dependent upon the materials recovered, and the research question addressed. Studies completed include lithic technological analysis, ceramic analysis, faunal analysis, shell analysis, obsidian source analysis, pollen analysis, and radiocarbon dating. Specialized studies on speciflc material classes are discussed below. 2.5.1 Lithic Analysis 2.5.1.1 Analytical Methods Technological lithic analysis based upon replicative data was conducted for all flaked stone artifacts recovered. All lithic artifacts were also examined on the basis of raw material types and reduction stage categories. Reduction stage flake categories were defined by comparing technological attributes of replicated artifacts from known and catalogued flaked stone tool reduction technologies to prehistoric controls. In tum, by comparing the prehistoric artifacts (controls) to the known artifacts in terms of manufacture, reduction stages were assigned to PJ. 4-04 ' 2-13 August 2005 I I I I technologically diagnostic debitage. Some debitage, however, was considered technologically nondiagnostic because of the lack of attributes on fragmentary pieces. Technological debitage analysis based upon replicative data (Flenniken 1981) was selected over other analytical methods to obtain processual reduction stage identifications. Methods such as size grading (Abler 1989), or morphological attribute analyses (length, width, thickness, weight, or completeness of flake)(Sullivan and Rozen 1985) do not allow processual anthropological modeling of specific technological activities. Analyses dependent on mefric data provide the analyst with size-descriptive information only; they do not allow reliable identification of prehistoric behaviors. Mefric analyses do not take into account cracial variables such as raw material type, quality, shape, and flakeability, nor do they consider the skill level of the prehistoric knapper, the reduction sequence(s), or the intended end product(s). Size grading of debitage as a form of "technological" analysis is also ineffectual as a means of providing accurate prehistoric lithic technological information (Scott 1985, 1990, 1991). In one case where samples of debitage from six different sites were subjected to both size-grading analyses and technological analyses in an effort to define the lithic reduction activities that occurred at each site, Scott (1985) found that "...size-grading artificially separates debitage into classes that do not accurately reflect lithic reduction." Ahler's (1989) work conceming size-grading analysis or "mass analysis of flaking debris" is the most comprehensive study to date. However, even using experimental confrols, size-grading analysis proves inadequate for making inferences as to the reduction process because of the qualifications placed on interpretive comparisons. For example, Ahler's (1989) reduction model does not apply to multiple material sites wherein the size, shape, and quality of the original raw materials may have influenced reduction sfrategies. Multiple flaking episodes are said to require interpretation through multivariate statistical analysis even though statistics are not capable of "interpreting" data. Ahler's (1989) approach provides little or no accurate technological information conceming lithic reduction techniques because of inherent methodological errors regarding scientific experimental procedure. Reasoned sampling of large assemblages combined PJ. 4-04 2-14 August 2005 I I I I I I I 1 I I I with technological attribute and stage analysis is more informative than are low-level description of complete, large assemblages. Replicative systems analysis (RSA) is a methodological concept designed to understand the behavior prehistorically applied to flaked stone artifacts (Flenniken 1981). The method involves replicating, through flintknapping experimentation, a hypothesized sequence (based upon debitage frequencies documented during analysis) of lithic reduction employed at a particular archaeological site. By comparing the prehistoric debitage with catalogued experimental debitage, it is possible to determine the reduction techniques and sequence(s) that were employed at a given site by prehistoric knappers. Experimentation has also demonstrated that many by-products associated with tool manufacture can be mistaken for functional tools such as "scrapers" (Flenniken and Haggarty 1979). The RSA approach offers a reliable means to both identify and demonstrate the method(s) utilized by prehistoric knappers to reduce available stone into flaked stone tools and weapons. Because flintknapping techniques are learned rather than an innate behavior, reduction sfrategies can be both culturally and temporally diagnostic (Flenniken 1985; Flenniken and Stanfill 1980). Thus, by studying, the reduction technologies employed at archaeological sites, it is possible, once the technological foundation based upon numerous technological analyses has been established, to correlate sites in time and space by identifying related or similar lithic technologies (Flenniken and Stanfill 1980). The correlations may aid future research involving descriptions of regional mosaics of human activity pattems as they vary through time. In regions where volcanic or acidic sediments preserve very little of the archaeological record except stone artifacts, or where prehistoric activities left little or no frace, this method of gathering information can be exttemely productive. The RSA approach to lithic analysis is useful and appropriate because it focuses on determining what lithic technologies were used at a particular site, how these technologies may have changed through time, and whether these changes correlate to specific time periods. Attributes evidenced on the prehistoric debitage, in conjunction with experimental analogs, were used to identify technologically diagnostic debitage, enabling flakes to be assigned to specific experimentally derived reduction stages (Flenniken 1978, 1981). The remaining debitage was not PJ. 4-04 2-15 August 2005 I I I I I I I I I I I I I I I I i I ascribed to any reduction stage because of the fragmentary nature of the specimens. These specimens were characterized as technologically nondiagnostic, although attributes such as material type, heat treatment, and presence/absence and type of cortex were noted. Debitage classification atfributes were divided into reduction-oriented technological categories, and these categories were then segregated into stages. Stage 1, core reduction debitage, is defined on the basis of amount and location of cortex on the dorsal surface, platform atfributes, dorsal arris count and direction, and flake cross/long-section configuration. Stage 2, bifacial reduction debitage, is classified on the basis of multi-faceted platform configuration and location, location of remnant bulb of force, dorsal arris count and direction, flake termination, flake cross/long-section orientation, and presence or absence of detachment scar. Stage 3, percussion bifacial thinning debitage, is segregated on the basis of multi-faceted platform configuration, size, lipping and location, dorsal arris count and direction, flake termination, cross/long-section orientation, and presence or absence of detachment scar. Stage 4, pressure bifacial reduction debitage, is separated on the basis of multi-faceted platform configuration and location, dorsal arris count and direction, flake termination, platform-to-long axis geometry, cross/long-section orientation, and presence or absence of detachment scar. Nondiagnostic fragments (flake fragments, with or without cortex) were defined as such. These reduction-oriented technological categories were further segregated on the basis of geological material types such as metavolcanic, vein quartz, metasedimentary, quartzite, chert, and obsidian. Interpretation of the reduction sequence from this site was determined using only the technologically diagnostic debitage, whereas discussions conceming lithic raw material types include all debitage and formed artifacts. A 100% sample of the debitage, recovered from excavation units, was analyzed, identified, and assigned to specific technological categories and stages. Technologically diagnostic debitage was assigned to a specific reduction category, and. served as the basis for interpretation of lithic technology. Since the artifacts recovered from the site are intra-site similar in technological character, the sample of the entire excavated assemblage may be small, and technological change from level one through the deepest level may not be identified. Consequently, all artifacts from the site may be combined for the purpose of interpretation ofthe site's lithic technology. PJ. 4-04 2-16 August 2005 I I I I I I I I I I I I I i I 1 I I Not all flaked stone reduction technologies are the same throughout prehistory even within one locality such as southem Califomia, or within one formed artifact class. For example, biface reduction sequences may vary technologically from site to site as a result of cultural/temporal differences even though the same raw lithic material is present at these sites. By identifying technologically diagnostic debitage from sites, specific reduction technologies can be easily segregated. 2.5.1.2 Ground Stone Tools These tools were used primarily for vegetal processing; however, ethnographic records indicate that bone, clay for pottery, and pigments for paint were also ground using these implements (Gayton 1929; Kroeber 1925; Spier 1978). Ground stone tools were first separated into four groups: manos, metates, pestles, and mortar/bowls, recognizing of course that all four groups in actuality feature complex tools that have two primary parts. Attributes selected for the discussion of ground stone tools are most amenable to comparisons with similar artifacts from other sites in the region. Manos: Atfributes important in the classification of manos include cobble or shaped, number of faces used (bifacial or unifacial) to determine extent of usage, end-battering (presence or absence resulting from roughening grinding surfaces), outline, and cross-section. The shape of a mano can aid in identifying the type of metate (i.e., shallow or deep basin) used in association with the mano. Shaping is important in determining the length of occupation of a site; as the time needed to shape a proper mano would not be taken if the user only meant to employ the mano for a short period of time and then discard it. Shaping denotes an unnecessary amount of time expended to make an object aesthetically pleasing. Metates: Ground stone fragments are identified as metate fragments based on the presence of at least one concave ground surface. Both slab (thin and highly portable) and block (thick and heavy) metates may be present. Some may have been used unifacially and others bifacially, denoting the amount of time spent grinding.

These items may denote status, and include beads and pendants, or, in the case of ritual/ceremonial activities, shaman crystals and hematite (red or yellow paint stone). Other items classified under the miscellaneous category include tarring pebbles, boiling stones, and manuports. 2.5.2 Ceramic Analysis Ceramic analysis is valuable in the interpretation of an archaeological site, as it provides data on the activities of the people who once occupied the site, the clay sources, and trade and ttavel. Typically, when ceramics are recovered from an archaeological site in the San Diego region, they are found in small quantities. Moreover, the collection usually consists of small, fragmented body sherds, and a few rim sherds. Without diagnostic pieces (incised, decorated, etc.) or whole vessels, analysis of vessel attributes, vessel morphology, and specific activities cannot be addressed. In a situation where there are few , ceramic sherds to examine, a different type of analysis may be more usefiil. Petrographic analysis of ceramics allows the researcher to identify mineral inclusions ofthe ceramics that are specific to geologic zones, providing data on fhe possible frade and movement of the people who once occupied the site. For large ceramic collections, pettographic analysis is also helpful, as it provides information on local clay source preferences. In the San Diego region, ceramic artifacts are created from local clays in the mountains, or from clays farther east from different areas of the desert. To differentiate which clays are local and non- local, clays need to be identified in relationship to their geological source. The different geologic zones that make up the San Diego region include the coastal plains, the Peninsular Range Mountains, and the Salton Trough desert. The coast and desert regions contain alluvial clays derived from marine and lacustrine sedimentary rock, while the Peninsular Range Mountains contain residual clays derived from gabbroic-granitic materials. An analysis of the mineral composition of the ceramic sherd must be conducted in order to identify the geological source from which the clay was obtained. The type of ceramic ware can be identified, once the geological source of the clay has been determined. PJ. 4-04 2-18 August 2005 i 1 0 I f i i i I i I I 1 I I I t I 2.5.2.1 Ceramic Wares in the San Diego Region Ceramic wares within the San Diego region include Tizon Brown Ware, Salton Brown Ware, and Colorado Buff Ware, as well as other desert wares that are not commonly seen west of the Peninsular Range Mountains. • Tizon Brown Ware Previous attempts to produce ceramic ware typologies for San Diego County has resulted in the identification of two different ware types: brown ware and buff ware (Rogers 1936). Brown wares, referred to as Tizon Brown Wares, are frequently associated with the mountain region. Tizon Brown Ware is the most common ware in San Diego County. The term Tizon Brown Ware was originally associated with the northwestem Arizona region, and many southem Califomia ceramics were later included under this name (Euler 1959). As a result, there has been a tendency to classify southem Califomia ceramics under the all-inclusive Tizon Brown Ware type, without any subtypes. Although this classification suggests some regional continuity between Arizona and southem Califomia ceramics, that is not the case. Problems arise with this classification because many variations of Tizon Brown Ware have been recovered in southem Califomia. Moreover, many brown ware sherds are not restricted to mountain sites, and can be found along the coast and inland near the Salton Sea (Van Camp 1979). Tizon Brown Ware vessels were shaped using the paddle-and-anvil technique, and were made from residual granitic-derived clays. Residual clays are found primarily in the mountain and coastal areas of San Diego County. These clays are the end products of weathering, and the breakup of gabbroic and granitic outcroppings of the Peninsular Range Batholith. Along the west side of the Peninsular Range, gabbroic rocks dominate, and are characterized by a high concentration of plagioclase and amphibole. Along the east side, which slopes and extends into the desert region, granitic rocks dominate. Consequently, there is an apparent decline in the amount of amphibole in the granitic rocks (east side), but a greater concentration of mica (biotite and muscovite) and quartz (Hildebrand et al. 2002). Therefore, clays from the east, granitic side have few or no amphibole minerals (Hildebrand et al. 2002). The clays contained in Tizon Brown Ware originate along the westem, gabbroic side of the Peninsular Range and thus contain inclusions of plagioclase, quartz, mica, and amphibole. PJ.4-04 2-19 August 2005 Jl I II I I I i I I 1 i I I I I • Lower Colorado Buff Ware The other common ceramic ware found in southem Califomia is buff ware. Buff ware ceramics are often referred to as desert wares, and are also known as Lower Colorado Buff Wares. Buff wares are made from sedimentary clays that result from the mixture of soil and water. Coarse particles are -left behind, while fine particles are deposited some distance from the parent source. Sedimentary clays are finer in texture and have a more homogenous composition when compared to mountain clays (Rice 1987). These clay types can be found in former lake bottoms and alluvial deposits in the Colorado Desert, and in Imperial County near ancient Lake Cahuilla. The minerals contained in Lower Colorado Buff Ware include quartz, feldspar, rare instances of amphibole, and sometimes mica. Lower Colorado Buff Ware vessels found in the San Diego region were also shaped using the paddle-and-anvil technique. • Salton Brown Ware The general classification for ceramic wares in the San Diego region does not allow for a third type of ware that is found in the San Diego region, Salton Brown Ware. Salton Brown Ware is another desert ware, similar in appearance to Tizon Brown Ware. Lower Colorado Buff Ware is easily discemible from the two types of brown ware. However, distinguishing Salton Brown Ware from Tizon Brown Ware is not as sfraightforward. These two brown wares cannot be differentiated based on visual inspection alone because their exteriors are so alike. One of the main factors distinguishing Salton Brown Ware from Tizon Brown Ware is the absence of amphibole, a rock- forming mineral that weathers into clay (Rice 1987). Salton Brown Ware originates along the eastem side of the Peninsular Range (westem Salton Trough sediments), and has a higher content of mica, quartz, and a rare instance of amphibole when compared to Tizon Brown Ware (Table 2- 1). Salton Brown Ware vessels were also shaped using the paddle-and-anvil technique. In order to differentiate between the different wares, a fresh edge must be broken off the sherd to examine the cross section. Examining the exterior of the sherd does not provide enough information about the mineral composition, and can lead to mistakes in ceramic ware identification. PJ.4-04 2-20 August 2005 Table 2-1 Average Mineral Compositions for Brown Wares* Ceramic Type Quartz Plagioclase Biotite Muscovite Amphibole Rock Salton 61% 11% 15% 6% 4% 4% Tizon 51% 20% 4% 1% 20% 1% * adapted from Hildebrand et al. 2002 For example, mica observed on the surface of a sherd has been, in the past, mistakenly identified as part of the mineral composition of the sherd, rather than an end result of pot manufacture. In Hildebrand et al.'s (2002) study, both ttace-element (NAA) and pettographic thin-section analyses were used to examine a representative sample of ceramic sherds for south San Diego County. Salton Brown Ware sherds had an average mineral composition of 61% quartz, IP/o plagioclase, 15% biotite, 6% muscovite, and 4% amphibole (see Table 2-l)(Hildebrand et al. 2002). Analysis of the Tizon Brown Ware sherds indicated an average mineral composition of 51%o quartz, 20% plagioclase, 4% biotite, 1% muscovite, and 20% amphibole (see Table 2-1) (Hildebrand et al. 2002). These results suggest that Salton Brown Ware has a higher percentage of quartz and mica, and almost no amphibole, while Tizon Brown Ware has a higher percentage of amphibole and plagioclase. 2.5.2.2 Petrographic Thin-Section As a result ofthe current fieldwork, a total of 449 sherds were recovered from site CA-SDI-8303, and a total of 260 sherds were recovered from site CA-SDI-8694. All sherds were not included in the ceramic analysis as some were too small to obtain a thin-section sample. A total of 289 sherds from CA-SDI-8303, and 252 sherds from CA-SDI-8694 were included for sample selection. Ceramic sherds were first placed into different sample groups based upon mica (biotite and muscovite) concenfration, sherd thickness, rim shape variability, surface color, and core color. Sherds with recent broken edges were checked to see if they mended with other sherds within the sample group. Both procedures reduced the possibility of analyzing sherds from the same parent vessel. At site CA-SDI-8303, 11 different sample groups were identified, while 15 different sample groups were identified for site CA-SDI-8694. After all the sherds had been placed into different sample groups, each group was placed into plastic bags and a random sherd was selected as the representative sample for each group. Twenty-six ceramic sherds were submitted to the San Diego Pefrographics Laboratory in Escondido, Califomia, for the creation of thin-section samples. Each sherd was enveloped in epoxy resin, then polished and cemented to a glass slide. The sample was then cut and polished to a thickness of 30 microns (^im), and sealed with a glass-cover slip. PJ. 4-04 2-22 August 2005 I I I I I I I I I I I I i I I I I I I Once the thin-section samples, along with what remained of the ceramic sherds, were retumed to Gallegos & Associates' laboratory, they were analyzed for mineral composition. Each thin-section sample was examined under a polarizing (petrographic) microscope by ttansmitted light (plane- polar and cross-polar) from 28X to 1500X magnifications. Important mineral characteristics that were considered when examining the thin sections include distinctive cleavage, twinning, alteration, zoning, exsolution, or the presence of inclusions. The following provides a description of these characteristics: Cleavage: Cleavage is the appearance of fine parallel cracks in mineral grains; minerals exhibit different types and intersecting angles of cleavage that aid in mineral identification. Twinning: Twinning denotes different regions of grain that have different crystallographic orientations that result in the appearance of horizontal or vertical bands. Alteration: Some minerals may be altered for some reason, such as weathering, resulting in secondary minerals, wherein a complete replacement of one mineral by another occurs. Zoning: The composition of mineral grains is heterogeneous, wherein different parts of minerals exhibit different optical properties. Exsolution: At high temperatures, some minerals exsolve, or unmix to form two distinct compositions during or after cooling. Inclusions: Some minerals tend to contain inclusions of specific types of minerals, and rarely contain mineral inclusions that are not of that type. The mineral inclusions were identified using the point-count method, with a minimum count of 100. Each slide was examined once under the polarizing microscope using the point count method and then a second time examining the entire slide for a general observation of the mineral composition. One last mineral characteristic that was considered in the current analysis was the shape of the quartz inclusions. Quartz inclusions that are rounded are likely from the desert, whereas quartz inclusions from the mountains tend to be angular. Rounded and angular quartz inclusions are a result of sedimentary versus residual movement of the clay deposits. Clays from the desert are sedimentary and have been moved by waves, tides, sfreams, wind, erosion, or other forces to produce quartz minerals that have become rounded from abrasive movement. In the mountain, clays are found near or at the location of the parent rock from which they developed. The movement is not as abrasive as in the desert, producing less attrition and resulting in angular quartz inclusions. PJ. 4-04 2-23 August 2005 2.5.2.3 Rim Sherd Profile Methods A rim sherd profile is a vertical measurement of the rim sherd. Rim sherds that were large enough to identify the arc of the rim and that were easy to orient were selected for profile samples. The rim sherd was placed upright and oriented along a right angle raler. The angles where the rim sherd intersected with the vertical and horizontal lines were plotted on graph paper. A carpenter's contour gage was placed alongside the interior of the rim sherd to obtain the contour of the rim sherd. The contour gage was then placed alongside the marked angles on the graph paper, and the interior contour of the rim sherd was outlined. The same procedure was done with the exterior of the rim sherd. Calipers were used to measure thickness and a concentric radii measurement tool was used to measure the radius ofthe rim sherd. 2.5.3 Faunal Analysis Shell was identified, sorted, counted, and weighed by species. Use of this data contributed to answering questions regarding diet, environmental setting and change through time, and settlement pattems. Bone, was identified by genus and species when possible. When species identification was not possible, the bone was identified to successively higher levels of classification, settling on terms such as small, medium, or large vertebrate mammal. Elements were then identified as bumed or unbumed. Where possible, cooking methods were discussed. Faunal information, including number of individual species and weight by species, was tabulated by unit and level. Where possible, age of capture of identifiable specimens was estimated. Bird bone, wherever possible, was identified to family, genus, and/or species, as the information about migratory birds can add to the data for determining seasonality. 2.5.3.1 Methods Each bone was examined to determine: 1) element; 2) right or left side; 3) highest taxonomic category; 4) evidence of buming, and if so, degree of oxidation; and 5) evidence of butchering, and if so, method of butchering. Comparative skeletal collections were used in the identification process from Scripps Institute of Oceanography, as well as from private collections. Bone atiases PJ. 4-04 2-24 August 2005 I I I I I (Lawrence 1951; Nickel et al. 1986; Olsen 1985; Sandefiir 1977; Schmid 1972) were also used to supplement the analysis. 2.5.3.2 Categories Categories used in this analysis include: (1) Bumed: Bone elements or fragments in this category show color change from exposure to heat or fire (oxidation). Colors may include: • brown: indicates exposure to heat, but little or no exposure to open flames. • black: shows direct exposure to open flames (i.e., roasting or discard in a fire). • blue/white (calcined): denotes direct exposure to a fire hotter than 800° Celsius (Ubelaker 1978), and may represent bone that was severely bumed during preparation. If flesh was present on the bone during exposure to the fire, the bone would exhibit signs of warping and shrinking (Ubelaker 1978). Calcined bone may also be the result of having been discarded in a fire hearth (Wing and Brown 1979). (2) Unbumed: No evidence of buming or oxidation. (3) Butchered: Bone with evidence of processing by slicing or chopping actions. (4) Bird: Bones that have thin walls in cross-section, are hollow, and light in weight. These are often distinguishable from mammal bone because they contain large cavities that would have been filled with air in life. (5) Lizard: Small animal bone fragments, which are usually mandible fragments with homodont teeth that are straight instead of curved like snake teeth, or long-bone fragments that are split and funnel-shaped, or vertebrae with ball and socket features with a flattened vertebral foramen. (6) Snake: Vertebrae with ball and socket features with a domed-shaped vertebral foramen. (7) Teleostei: Funnel-shaped vertebra with/without the spinous process attached, and other skeletal elements considered as bony fish. (8) Ray/Skate: Tooth plates that are from rays and skates, as well as spines and hooks. (9) Elasmobranch: Dram-shaped vertebra that are from cartilaginous fish (rays/skates, shark) When species identification as noted above was not possible, the bone was identified to successively higher levels of classification. These include: PJ.4-04 2-25 August 2005 (1) Small Mammal: All nondiagnostic vertebrate fragments, with size between a mouse and a jackrabbit. (2) Medium Mammal: All nondiagnostic vertebrate fragments, for which sizes are larger than a jackrabbit, but smaller than a deer. (3) Large Mammal: All nondiagnostic vertebrate, fragments, for which sizes are deer-size and larger. The quantification of faunal material studied is usually determined by the sample size and type of site under investigation. Two methods were used in this study: the number of identified specimens per taxon (NISP), which represents the total number of specimens within a category; and the minimum number of individuals (MNI), which represents the minimum number of individuals within a genus and species category. 2.5.4 Radiocarbon Dating Analysis A minimum of one to two samples of shell was selected for Accelerator Mass Specfrometry (AMS) radiocarbon analysis. Radiocarbon dating provides valuable information for site placement within the prehistoric chronology for San Diego County. 2.5.5 Obsidian Source Identification Obsidian samples were submitted for x-ray fluorescence analysis (XRF) source identification. Usually, the number of obsidian items recovered is small, and all samples large enough (1.0 cm in maximum measurement) will be submitted for analysis. In all, five obsidian samples were submitted for XRF source analysis. 2.6 NATIVE AMERICAN CONSULTATION Native American monitoring is not required for the present project, however, as Native Americans are interested and can confribute to cultural resource studies, a representative from the San Luis Rey Band of Mission Indians assisted with the project. Mark Mojado of the San Luis Rey Band of Mission Indians provided Native American monitoring services for this project, and a Native American monitor was on site daily. PJ. 4-04 2-26 August 2005 2.6.1 Provisions for Encountering Human Remains If human remains are encountered, then the specific procedures outlined by the Califomia Native American Heritage Commission (NAHC)(1991), and in accordance with Section 7050.5 of the Health and Safety Code Section 5097.98 ofthe Califomia Public Resources Code (Chapter 1492, Stattites of 1982, Senate Bill 297), and SB 447 (Chapter 44, Stattites of 1987) will be followed. Section 7050.5 will guide the potential Native American involvement, in the event of discovery of human remains. Specific measures to be followed should human remains be encountered are: 1) work will cease in the immediate area of the burial; 2) the person in direct charge of the project will contact the County of San Diego Coroner; and 3) as per Section 7050.5(c) "If the coroner determines that the remains are not subject to his or her authority, and if the Coroner has reason to believe that the human remains are those of a Native American, he or she will contact the Native American Heritage Commission." The Native American Heritage Commission, the local agency representative, and the authorized local tribal representative will review and provide input as to further action. Under typical circumstances, the. Most Likely Descendent(s) (MLD) of the discovered remains will then be contacted by the NAHC. The MLD has 24 hours to make recommendations to the Project Owner/Environmental Compliance Manager regarding freatment and disposition of the identified remains. Altematives for the disposition of human remains and associated burial-related artifacts include: 1) leaving human remains in situ; 2) uncovering the human remains for analysis in situ; 3) removing human remains for analysis and curation; 4) removing human remains for analysis and repattiation to local Native Americans affiliated with the local area; and 5) removing human remains with no analysis for repafriation to Native Americans affiliated with the local area. 2.7 CURATION All cultural resources, except burial-related artifacts and unless otherwise required by law, excavated or removed from prehistoric or historic sites during testing and/or data recovery programs, along with all associated project data, will be permanently curated at an institution PJ. 4-04 2-27 August 2005 acceptable to the reviewing agencies and the Luiseno Native Americans. The curation facility should be a qualified repository as defined by the "State of Califomia Guidelines for the Curation of Archaeological Collections," such as the San Diego Archaeological Center. Curation includes, but is not limited to, field records, catalogues, and final reports. Additionally, the owner agrees to execute a release of title form, and to pay the required curation fees in effect at the time of curation. All curation shall be accomplished within six (6) months from the completion of the project. 2.8 PERSONNEL Project personnel included Dennis Gallegos, Project Manager; Tracy Sfropes, Project Archaeologist/Lab Director; and Larry Tift, Field Director. Jeff Flenniken, Ph.D. and Tracy Sfropes provided lithic analysis for all debitage. Tracy Sfropes provided lithic analysis for all tools. Special studies included ceramic analysis by Monica Guerrero; faunal analysis by Patricia Mitchell; shell analysis by Tracy Sfropes; obsidian sourcing by Geochemical Research Laboratory; residue analysis by Robert Parr; and radiocarbon dating by Beta Analytic, Inc. Field personnel included Karen Hovland, Ryan Anderson, Lucas Piek, David Gallegos, and Julie Gallegos. Mark Mojado and Jason Gervais of the San Luis Rey Band of Mission Indians provided Native American . monitoring services. All illusfrations were completed by Tracy Stropes. Graphics were provided by Larry Tift and Tracy Stropes. GIS maps were provided by Nick Doose. Resumes for key personnel are provided in Appendix A. 2.9 MONITORING An archaeologist and Native American shall monitor all grading and earth-moving activities during constraction within the vicinity of each site. Should burials, cremations, or features be located, grading and/or earth-moving activities will be halted for a period of 72 hours to allow for excavation and removal of the deposit(s) in a timely and sensitive manner. Analysis of artifacts and ecofacts recovered during monitoring will be included as an addendum to the final report. PJ. 4-04 2-28 August 2005 SECTION 3 INVESTIGATIONS AT CA-SDI-8303 3.1 PREVIOUS WORK Site CA-SDI-8303 was recorded circa 1920 by Malcolm Rogers as the Kelly Springs site. Rogers noted that the site was located on both sides of a canyon. Cultural remains noted include'cobble hearths, shell, arrow points, and one bone pipe with three loop handles. Rogers also noted that Dewey Kelly found a cremation associated with ceramic sherds and the bone pipe. Subsequent surveyors included Franklin (1978); Hatiey (1979); Hanna (1980); and Douglas and Weil (1980). In 1986, Wade monitored backhoe ttenching performed by SDG&E. Based on her observations, she described the site complex as "composed of several elements which overlap, have been disturbed, and are spatially separated," so that the exact site size was difficult to determine. In 1998, the site was tested by Gallegos & Associates (Gallegos et al. 1999) to determine site significance. The testing included the excavation of51 shovel test pits (STPs) and five Ixl-m units (see Figure 1-3). This work produced over 1,107 artifacts that include a wide range of tools, beads, a Haliotis sp. (abalone) fishhook, ceramics, arrow points, milling tools, 13,730.85 g of shell, and 122.75 g of bone (see Table 1-2). Site CA-SDI-8303 is a major village site, occupied circa 760 to 1,080 years ago. The shell reflects both lagoon and open coast shell exploitation. Obsidian was also recovered and sourced to Obsidian Butte in the Imperial Valley. Other trade material includes chert, wonderstone, siltstone, and Piedra de Lumbre chert. 3.2 CURRENT STUDY The Indexing and Preservation Study for CA-SDI-8303 included field excavation of six Ixl-m units (Figure 3-1), collection of surface artifacts, artifact cataloguing, data analysis, and special studies. The purpose of the Indexing and Preservation Study for CA-SDI-8303 was to provide an index sample representing the deposit being capped, protected, and avoided of impacts. The fieldwork resulted m the collection of 6 bifaces, 9 arrow points, 1 biface preform, 1 flake blank, 10 battered implements, 18 flakes from battered implements, 3 steep-edged unifacial tools (SEUTs), 2 rejuvenation flakes from SEUTs, 6 flake tools, 1 flake knife, 3 cores, 3,887 debitage, 1 nodule tool, PJ.4-04 3-1 August 2005 HEAVY RIPARIAN VEGETATION - ENLARGED AREA INSET SHOWING CA-SDI-8303 SIGNIFICANT SITE AREA 14 PUWJ 6 HI UNIT 7 H * 8. a UNITS B UNIT 11 13 12 I KEY A = Site Datum 11 =1x1 Meter Unit • 1 = Surface Collection Point Gallegos & Associates / 8 I UNIT 9 .9 • 10 • 1 ' 4 10M SCALE CA-SDI-8303: Detail Map of Indexed Area Showing Surface Collection Points and 1x1 Meter Units FIGURE 3-1 6 ground stone fragments, 19 manos, 5 metate fragments, 1 polished stone fragment, 449 ceramic fragments, 12 Olivella sp. shell beads, 7 shell disc beads, 1 Cypraea spadicea Swainson (Chestiiut Cowry) shell, i bone bead, 2 glass trade beads, 1 quartz crystal, 1 fragment of pitch, 2 otoliths, 2 bone tools, 465.4 g of bone, and 32,838.1 g of shell (Table 3-1). 3.2.1 Surface Collection A surface collection was completed to ensure that exposed surface artifacts were collected prior to capping activities. The totaf artifacts collected from the surface include 3 debitage, 2 SEUTs, 3 battered implements, 8 manos, 5 metates fragments, and 1 ground stone fragment (see Table 3-1). 3.2.2 Unit Excavation A total of six 1x1-m units were excavated at CA-SDI-8303. Unit selection was based on random sampling within the primary site area. Units 1 through 5 were excavated during the test phase (Gallegos et al. 1999), and Units 6 through 11 were excavated as part of the present indexing study. Units 6,8,9,10, and 11 were selected for water screening. Soil sfratigraphy forthe units excavated conform to primarily one single depositional pattem across the site (Figure 3-2). This pattem exhibited a topsoil of loose, brown sandy loam (Munsell 7.5 YR 4/2) disturbed historically by agricultural activities. This loam ranged from 0-30 cm and contained a moderate amount of cultural material. The topsoil was generally followed by a moderately compacted, dark brown sandy loam (Munsell 7.5 YR 3/2) with occasional rocks, beginning at depths ranging from 15 to 35 cm, and terminating between 30 and 90 cm in depth. This level contained the bulk of cultural materials recovered from CA-SDI-8303. Finally, all units terminated between 40 and 90 cm within a dark gray-brown sandy clay (Munsell 7.5 YR 3/1) primarily devoid of cultural material. While the developed, cultural material-bearing soil observed in the secondary layer remained consistent throughout the site (dark brown sandy loam, Munsell 7.5 YR 3/2), the underlying subsoils varied in accordance with site topography. Unit excavation descriptions are provided below by unit number. Units 1 through 5 were excavated as part ofthe test phase (Gallegos et al. 1999). Units 6 through 11 were excavated for the site indexing and preservation study. Sfratigraphic profiles and unit tables are provided in Appendix D.

The following sections describe the analysis for all materials recovered from the present indexing study. 3.4 DEBITAGE ANALYSIS (by Jeff Flenniken and Tracy Sfropes) 3.4.1 Methodology Technological lithic analysis based upon replicative data was conducted for all flaked stone artifacts identified from this debitage sample recovered from CA-SDI-8303. Technological identifications were determined for all analyzed flaked stone artifacts. Lithic artifacts were categorized according to toolstone material type (metavolcanic, quartz [quartzite, vein quartz, quartz crystal], chert, and obsidian), technological category (tecat), and reduction stage (Appendix B). Reduction stage flake categories were defined by comparing technological attiibutes of replicated (experimental) artifacts from known and cataloged flaked stone tool reduction technologies to the prehistoric conttols. In tum, by comparing the technological attributes of prehistoric artifacts (conttols) to the technological attributes of known artifacts in terms of manufacture, reduction stages were assigned to technologically diagnostic debitage. Some debitage, however, was considered technologically nondiagnostic because ofthe lack of technological attiibutes (i.e., platforms) on fragmentary pieces. PJ. 4-04 3-14 August 2005 Attributes evidenced on the prehistoric debitage, in conjunction with experimental analogs, were used to identify technologically diagnostic debitage that enabled flakes to be assigned to specific experimentally derived reduction stages (Flenniken 1978,1981). The remaining debitage was not ascribed to any reduction stage because of the fragmentary nature of the artifacts. Therefore, fragmentary debitage was characterized as technologically nondiagnostic, although attributes such as material type, and presence/absence and type of cortex were noted. 3.4.2 Analyzed Sample The debitage included in this analysis was archaeologically recovered from five excavation units. In Unit 6, six (1x1x0.1 m) levels were excavated; Unit 7, nine levels; Unit 8, six levels; Unit 9, six levels; and Unit 11, eight levels. A total of 35 (1x1x0.1 m) levels were excavated to produce a flaked stone assemblage sample of 3,887 artifacts. Each flaked stone artifact from this excavated sample was analyzed and recorded as a separate entity in an attempt to identify and isolate technological variation. Evidence to support intentionally different technological freatment of different lithic materials within the analyzed sample was not identified. The different lithic materials (metavolcanic, quartz, chert, and obsidian) identified from this infra-site sample were reduced following a similar reduction sequence to manufacture similar end products. Therefore, because of the lack of infra-site technological variation, the lack of differential lithic reduction freatinent, and the small sample (n=650) of technologically diagnostic debitage, all flaked stone artifacts and materials were combined for site interpretation. For example, in an attempt to identify evidence to support intentionally different technological treatment of different toolstone materials within the analyzed sample, the quartz, chert, and obsidian debitage were separated in an attempt to identify biface reduction activities that may have occurred at this site (see Appendix B). It was suspected that if biface manufacture occurred at this site, bifaces would have been produced from the non-metavolcanic materials, as Santiago Peak Metavolcanic (light green, fine-grained, homogeneous, and check-free) material, the most common biface (for larger bifaces) toolstone in the area was not identified in this sample in any quantity. This attempt to segregate technological variation proved ineffectual as all toolstone materials were technologically tteated the same by the prehistoric knappers. PJ. 4-04 3-15 August 2005 Furthermore, the analyzed debitage recovered from these five subsurface contexts were similar in technological character, and even by combining materials, the technologically diagnostic debitage (n=650, 16.7% of the total 3,887 flakes and flake fragments) still provided a small sample for interpretation. Therefore, all technologically diagnostic flaked stone artifacts from this analyzed sample were combined for the purpose of specific site interpretation conceming flintknapping activities. Again, only the technologically diagnostic debitage was employed for interpretation of CA-SDI-8303 flintknapping activities. As mentioned above, the recovered technologically diagnostic flaked stone sample from this excavated site was small (n=650), only 16.7% of the recovered debitage. A small technologically diagnostic flaked stone sample, in association with a homogeneous flaked stone sample that lacked technological variation even between different toolstone materials, were additional reasons to combine technological data for interpretation of specific site flintknapping activity. 3.4.3 Technological Artifact Categories (tecats) Technological analysis of the debitage from this CA-SDI-8303 sample identified a very interesting, and limited technologically, flaked stone tool assemblage. The technological end of one reduction continuum (flake core), or the last stage of reduction, was well represented at this site. Debitage classification attributes were divided into technological categories (tecats) that reflect technological differences in the reduction continuum and reduction stages that occurred at this site (see Appendix B). Continuum is defined as a process that includes the entire life cycle of a specific flaked stone tool (including all debitage) from the selection of the raw lithic material, initial decortication, heat treatment (if applicable), reduction into the original tool, use and reuse of that tool (which may be multi-functional), rejuvenation of that tool, the deposition of that tool into archaeological context, and possible reuse of that tool later in prehistoric time. Reduction stage, as employed for this analysis, is a concept designed to separate a flintknapping continuum for analytical purposes only. The reduction-oriented technological stages (processes) employed in this analysis, the flake categories, based upon replicated artifacts that correspond to those processes, and the flake attributes used to define those categories are, with few exceptions, within the nodule core reduction technology that was well established in prehistoric southem Califomia. PJ. 4-04 , 3-16 August 2005 Nodule core reduction is known in the southem Califomia archaeological literature as "Cobble Core Reduction" (Gallegos et al. 2002; Gallegos et al. 2003). The term nodule was substittited for cobble because the term cobble is geologically defmed as a size clast (64-256 mm) and many prehistoric core and core-based artifacts (such as some battered implements) were manufactured from boulders (>256 mm), and to a much less extent, pebbles (4-64 mm). The term nodule was selected because a nodule can be any size and tends to be somewhat rounded to subrounded. Nodule core debitage was recognized and grouped into technological categories based on the amount and location of dorsal cortex, platform atttibutes, dorsal arris count and direction, and flake cross/long-section shape. Debitage was classified according to three platform types identified among the flakes from nodule core reduction: natural/cortical platforms (NP), single-faceted platforms (SEP), and multi-faceted platforms (MFP). Flakes were further subdivided according to the location of dorsal cortex (tecats include NP-1 through NP-11, SFP-1 through SFP-11, and MFP- 1 through MFP-1 l)(see Appendix B). The reduction-oriented technological categories of diagnostic flakes were also segregated on the basis of geological material (metavolcanic, quartz [quartzite, vein quartz, quartz crystal], chert, and obsidian). Flake fragments that lacked the necessary atfributes to be placed in one of these reduction-oriented'tecats were classified as technologically nondiagnostic debitage with and without cortex. Only raw material type and presence or absence of cortex were recorded for these artifacts. Interpretation of the reduction sequence from this site was determined using only the technologically diagnostic debitage, whereas discussions conceming lithic raw material types include all debitage and formed artifacts. Metavolcanic nodules (cobbles and boulders) were selected for size, shape, material quality, and platform location. Nodules with natural platforms were reduced directly by percussion in a circular marmer around tbe natural platform. The location of dorsal cortex indicates the sequence of flake removals (see Appendix B). Cores with faceted platforms were nodules that required platform preparation prior to reduction. This occurred usually when a nodule of quality material was selected, but the nodule did not possess a naturally appropriate platform. It was therefore necessary PJ. 4-04 3-17 August 2005 I I I to create a platform by percussion flaking. The desired products of nodule core reduction were flake blanks that were thick in cross-section, long and narrow in planview, and ranged in length depending upon intended use, but were most likely 5 to 12 cm in length. 3.4.4 Toolstone Materials The lithic materials employed by the prehistoric knappers at this site included a variety of metavolcanic rock, quartz [quartzite, vein quartz, monocrystalline quartz], chert, and obsidian, mostly all collected from alluvial deposits. Obsidian is the only non-local toolstone material identified in the assemblage sample. All (100%)) ofthe identified cortex was incipient cone cortex resulting from water fransportation ofthe lithic nodule; toolstone was prehistorically collected from alluvial (past or present) environments. Metavolcanic materials are found as pebbles, cobbles, and boulders derived from Eocene volcanic rhyolites, andesites, and diabase of basaltic composition (Clevenger 1982). These materials have been extensively metamorphosed causing stmctural recrystallization and a rather porphyritic nature (Clevenger 1982). Metavolcanic rocks range in color from green to brown to black and require great dynamic loading forces to fracture conchoidally. Distinctive Santiago Peak Metavolcanic (known locally as "felsite"), found as bedrock in San Diego County and redeposited as float, was poorly represented in this analyzed assemblage. Quartz is one ofthe most common lithic materials, and occurs in a wide variety of hexagonal prisms that are terminated by pyramidal shapes. It also occurs in massive, granular, concretionary, stalactitic, and cryptocrystalline habits (i.e., vein quartz). When combined with other materials, quartz or metaquartzite is referred to as quartzite, whereas a single crystal is called monocrystalline quartz. Colors range from white, red, grey, purple, yellow, brown, pink, black, green, and can be colorless as well. Quartz is fransparent to translucent with some forms occurring as opaque (i.e., quartzite). Quartz has a hardness of 7, a specific gravity of 2.65, and fracttires conchoidally (Chesterman 1995; Klein andHurlburt 1985; Luedtke 1992; Pellant 1995). PJ. 4-04 3-18 August 2005 I I Chert is an opaque form of microcrystalline quartz composed of numerous grains that form a granular crystalline stracture. Chert and jasper are chemically precipitated sedimentary rocks classed as microcrystalline, but may contain sheaf-like aggregates that may include impurities such as clays, silts, carbonates, pyrites, iron, or other organic materials. Chert and jasper also may contain several forms of silica such as opal, chalcedony, or cryptocrystalline quartz. Cherts range in color from white to light gray to black. Jasper, because ofthe iron, is red, yellow, or brown. Green jasper is called prase or chyrsoprase. Jasper is distinguished from chert on the basis of color (Chesterman 1995; Klein and Hurlburt 1985; Luedtke 1985; Pellant 1995). Obsidian is an igneous glass that is non-crystalline and often has a bright vifreous luster. Obsidian has a specific gravity (G) of 2.4 and is slightly harder than common window glass (H=5.5). It forms as a result of the rapid cooling of extrasive magma, preventing any crystalline growth, or as a result of a viscous magma that was too rigid to support crystalline growth. Obsidian is usually black, but gray, red, brown, green, and even blue are common in specific geological locations in westem North America. The red colors are due to the inclusion of magnetite or hematite. Obsidian is usually franslucent, but can occur as fransparent or opaque (Chesterman 1995; Klein and Hurlburt 1985; Luedtice 1992; Pellant 1995). 3.4.5 Analytical Reisults: Technologically Diagnostic Debitage • Introduction This analyzed debitage assemblage consisted of 3,887 flakes and flake fragments (and two small biface fragments) manufactured from four different raw lithic material groups. A total of 650 (16.7%) artifacts were technologically diagnostic, while 3,237 (83.3%)) flake fragments were technologically nondiagnostic (Tables 3-8 and 3-9). Of the 650 technologically diagnostic artifacts, in the present CA-SDI-8303 sample, 586 artifacts represent nodule core reduction technology, and 64 artifacts represent biface reduction (see Table 3-8).

As mentioned above, an attempt to isolate technological variation between different lithic materials was not productive, as all toolstone materials were technologically freated in a similar manner. The quartz, chert, and obsidian debitage represented in this sample included only Stage 1, core reduction, flakes that were most likely confined to nodule core reduction debitage (see biface reduction stages and tecats in Appendix B). Therefore, the 144 technologically diagnostic Stage 1, core reduction, flakes are identified and included in nodule core counts as 101.PI=NP-1; lll.SI=NP-8; 113.SS=SFP-8; 121.II=NP-11; 122.IS=SFP-11; 123.IM-MFP-11; 127.IS=SFP-11; and 128.IM-MFP-11 (see Table 3-8). Three nodule core platform types (NP, SEP, and MFP) were represented in this debitage sample (see Appendix B and Table 3-8)(Gallegos et al. 2002; Gallegos et al. 2003). Nattiral platform (NP) debitage was represented by 380 flakes, single-faceted platform (SEP) debitage was represented by 163 flakes, and multi-faceted platform (MFP) debitage included 43 flakes (see Table 3-8). the most frequent (n=359) natural platform debitage category was NP-11, or flakes devoid of dorsal surface cortex (see Table 3-8). This tecat is produced well after cortex removal and flake blank production is in fiill force. Given the small overall size of the NP-11 flakes identified during this analysis, these flakes were most likely produced at the very end of flake core reduction just prior to the core becoming exhausted and discarded, and/or laterally cycled into another functional tool such as a battered implement. The remaining 21 other nattiral platform flakes were produced throughout the reduction cycle, and exhibited dorsal cortex (see Table 3-8). The same technological reduction pattem was repeated, almost identically, in the single-faceted platform debitage and the multi-faceted platform debitage (see Table 3-8 to compare NP tecats to SEP and MFP tecats)(see Appendix B). The most commonly occurring (n=144) single-faceted platform debitage category was SFP-11, and the most common (n=3.9) multi-faceted platform debitage tecat was MFP-11 (see Table 3-8). Most ofthe recovered debitage was too small for flake blanks, or was broken, or too thick, and was therefore discarded. PJ. 4-04 3-22 August 2005 For the most part, the CA-SDI-8303 nodule core debitage sample is small in overall size (< 3 cm long). This debitage produced from flake cores was placed into two general technique categories: rejected flake blanks or working face preparation flakes. Rejected flake blanks may be the appropriate length (> 5 cm), but were rejected because they were too thick, too narrow, covered with too much cortex, too many stacked step fractures on the dorsal surface, broken by sheared cones (very common at this site), etc. Working face preparation flakes are generally too small (< 3 cm), triangular in cross-section, and thick for use as they were most frequently produced as platform over-hang removal flakes, and/or to sfraighten the arrises on the face of the core. Useable flake blanks may have been transported from the site for use elsewhere. • Biface Reduction As mentioned above, diagnostic debitage was separated into tecats that may support the very beginnings (flake blank manufacture from flake cores) of biface reduction, but this debitage also exhibited tecats of nodule core reduction (see Appendix B). Separation was based upon technological attributes conceming material quality, flake thickness, number and position of dorsal arrises, platform type and size, and flake cross/long-sections. Therefore, the quartz, chert, and obsidian flakes possessed Stage 1, core reduction attributes, and the beginning of a biface reduction sequence. Knowing that only an entire flaked stone assemblage can accurately reflect the complete technological character of an archaeological site, these "biface" flakes were separated to detemiine if biface reduction actually occurred at this site (see Appendix B). Percussion biface manufacture was not well represented in this sample, as only 28 of the 200 segregated quartz, chert, and obsidian artifacts represented biface reduction (see Table 3-8). Stage 1, core reduction, debitage was discussed previously. Stage 3, percussion biface thinning, flakes were also identified in this site sample. Twenty-eight Stage 3 flakes represented biface manufacture (see Table 3-8). The four margin removal flakes (300.M-) are actual portions of biface margins removed as knapping errors when the knappers strack the biface margins too far from the edges, and/or the platforms were too stout. Stacked step fractures on the top surfaces of the bifaces may have also added weaknesses to the biface margins. The 24 early stage percussion bifacial thinning flakes (302.E-), created when bifaces are thinned and shaped, support biface production. PJ. 4-04 3-23 August 2005 These flakes are small and poorly formed, indicating that the bifaces produced were small, thick, most likely asymmetrical, and well within the arrow point size range. Pressure flaking was represented at this site (see Table 3-8) by 36 (5.5% of the technologically diagnostic debitage) Stage 4, early stage pressure bifacial thinning flakes (400.E-). These flakes were quite small and may represent biface edge rejuvenation and/or resharpening by pressure. These pressure flakes may have also been produced from non-bifacial tool resharpening or shaping. 3.4.6 Analytical Results: Technologically Nondiagnostic Debitage • With Cortex One hundred eighteen (84 metavolcanic, 5 quartz, and 29 chert) technologically nondiagnostic flake fragments that exhibited incipient cone cortex were examined for this analysis (see Table 3-9). Most of these flake fragments were broken during production by sheared cones, and were small, angular, and appeared to be by-products of nodule core reduction. • Without Cortex Two thousand one hundred nineteen (2,237 metavolcanic, 467 quartz, 396 chert, and 19 obsidian) technologically nondiagnostic, cortex-free flake fragments were also examined for this analysis (see Table 3-9). As with the cortical flake fragments, most of these pieces of debitage were small, angular, and also appeared to be by-products of nodule core reduction. Sheared cones, produced during flake production, created many of these flake fragments. 3.4.7 Technological and Functional Summary • Nodule Core Reduction Nodule core reduction technology is the most common core technology identified in this CA-SDI- 8303 sample (Gallegos et al. 2002; Gallegos et al. 2003). Products of nodule core reduction are also the most abundant as measured by percent (90.2%)) of technologically diagnostic flakes. This simple and expedient technology may have been so commonly used because it provided a simple and relatively effortless way to produce useful flakes, and flake blanks intended for immediate use PJ.4-04 3-24 August 2005 I I I I I I E I I i I I I I I I I I I Or further reduction. Because ofthe local (San Diego County) abundance of metavolcanic materials, there was often little need for more material-efficient, and consequently more time-consuming technologies. Debitage produced from nodule core reduction was classified according to the pattem of dorsal cortex present (if any), dorsal arris pattems, and platform attiibutes. Dorsal cortex attributes provide clues conceming two processes: stage of reduction and patterning of flake removals. The amount of cortex will decrease through the reduction sequence. Flakes with 100% dorsal cortex (NP/SFP/MFP-ls), therefore, usually result from earlier portions of the sequence while flakes with no dorsal cortex (NP/SFP/MFP-11 s) result from the latter portions of the sequence. The abundance of flakes that lack dorsal cortex exist because, once cortex is removed from a nodule early in the reduction sequence, all subsequent flakes will lack dorsal cortex. The positioning of dorsal cortex results from the patteming of flake removals (clockwise, counter- clockwise, or unpattemed in relation to the platform). The analysis of this debitage sample did, to a limited degree, reveal a potentially meaningful pattem regarding flake removal for some flakes. While nodule core reduction was the dominant flaked stone reduction technology practiced at this site, the Topaz Mountain reduction technique may have also been used to maximize the amount of flake blanks that could be produced from an oddly shaped, elongated pebble/cobble-size nodule of quality material. The Topaz Mountain technique is discussed later in this section. Another aspect of variability seen in the nodule core reduction debitage assemblages relates to platform characteristics. This variability also appears to result purely from technological considerations, rather than, for instance, a "mental template" to which might be attached some chronological or ethnic significance. Three examples of platforms are frequently found (unprepared/natural/cortical [NP], single-faceted [SEP], and multi-faceted [MFP]), and they vary, in part, according to the amount of shaping required to obtain a suitable platform configuration for successful flake removals (a uniform platform surface and adequate platform-to-core face angle). Some nodules did not require shaping (natural platforms) to obtain a proper platform configuration; others required more (multi-faceted platforms) or less (single-faceted platforms) shaping. It is PJ. 4-04 3-25 August 2005 expected that these different platform types could be produced within a single reduction sequence as a result of adjustments made in response to the changing shape of the core as it was reduced. One source of inter-site variation may relate to the portion ofthe nodule core reduction sequence conducted at a site. It appears that cores were not always entirely reduced at a single location, but rather initial shaping may have been performed at one site, and subsequent core reduction performed at another. This is indicated at some sites where few early stage flakes were found, but later stage flakes were common, such as CA-SDI-8303. Altematively, this pattem could be explained as a result of sampling bias resulting from incomplete, or non-representative artifact collections. • Topaz Mountain Reduction The Topaz Mountain technique is applied to a rounded-to-subrounded, elongated pebble, cobble, or boulder. A distal end of the elongated pebble, cobble, or boulder is removed by direct free hand percussion. The remaining flakes are produced by direct free hand percussion "sectioning" of the core, thus all flakes have cortical rim platforms. Four flake types frequentiy occur. Linear cortical flakes reflect the flintknapper' s attempt to flatten the working surface of a Topaz Mountain core. This step is necessary if large flat flakes are to be subsequently removed from the core. A cortical platform is required for the manufacture of linear cortical flakes. The platform occurs above and in line with an axis that divides the dorsal surface of the prospective flake into a portion containing cortex, and a portion containing a segment ofthe facet left by removal of the first split flake (Raymond 1984). Broad cortical (around the edges) flakes were produced after linear cortical flakes were removed from the core. To produce broad cortical flakes the knapper must hold the split core in one hand, with the split facet side facing away from the knapper. The other hand uses a hammerstone to strike the cortex of the core just above the perimeter ofthe split core face via direct free hand percussion. The point chosen for a platform depends on the angle formed by the core's working face and adjacent cortical surface. Generally, the most suitable location for a platform is in line with a ridge PJ.4-04 3-26 August 2005 I or undulation on the core's working surface, and at a ridge or area of high mass on the exterior cortical surface of the core (Raymond 1984). Under ideal circumstances the applied force fravels all the way through the Topaz Mountain core. This results in the largest and widest possible flake, and can be viewed as a successful "section" or "slice" of the core. Less ideally, the flake terminates with a hinge fracture in the middle of the working face of the core. Such "unsuccessful" flakes were discarded (Raymond 1984). As production of broad cortical flakes continued, the flintknapper rotated the Topaz Mountain core on an axis perpendicular to its working surface, aligning cortical platforms with working surface morphology for further flake removals. In the process, the core becomes smaller, yet the original cortex surface remains at the edge ofthe dorsal face of each flake (Raymond 1984). All flakes produced (except the first flake, which can be identified as a NP-1 flake) are technically versions of NP-5, NP-6, NP-7, NP- 10, and NP-11 flakes. However, these flakes are not removed to decorticate the nodule. Produced flakes serve as flake blanks for tool manufacture. The cortex remaining on the edges of the Topaz Mountain flakes has three fimctions: 1) to serve a consistent platform; 2) to serve as natural backing for flake tools; and/or, 3) to help maintain a flat flake during flake removal. The CA-SDI-8303 sample exhibits flakes and flake fragments that may have been produced using the Topaz Mountain technique. However, because of the high degree of sheared cones, these flakes could not be identified as being unequivocally produced by the Topaz Mountain technique. While virtually all NP-11 (as well as NP-4, NP-5, NP-6, and NP-7) flakes were broken as a resuh of sheared cones, it is expected that some of these flakes may have been Topaz Mountain flakes. • Adze Flakes Only two adze resharpening flakes were identified during the analysis of this debitage sample. This tecat (1005.AZ Flake) typically has a pronounced single-faceted platform (very few have cortical or multi-faceted platforms), multiple series of clusters of stacked step fractures on the proximal end of the dorsal surface, multiple linear flake scars and arrises (unidirectional from the platform or planer PJ. 4-04 3-27 August 2005 surface) on the dorsal surface, more or less parallel side margins, slightly curved in long-section, feather or stepped distal end terminations, and most importantly, have excessive polish (from contact with wood surfaces) with linear striations that are pattemed perpendicular, (or oblique) to the flake platform as well as the margin ofthe adze from which it was produced. Tecat 1005.AZ Flake specifies adze resharpening (see Table 3-8). 3.4.8 Conclusions The analyzed debitage assemblage from CA-SDI-8303 provided an example of a site wherein primarily the last stages of metavolcanic nodule core reduction (and possibly Topaz Mountain core reduction) occurred. Ofthe metavolcanic nodule core reduction flakes identified in this sample, 586 (90.2%) were NP-11, SFP-11, and MFP-11 (and may also include lOl.PI, 11 l.SL 113.SS, 121.11, 122.IM, 127.IS, and 128.IM)(see Table 3-8). Therefore, the primary flintknapping activity that occurred at this site was associated with metavolcanic nodule core reduction, and the predominant aspect of nodule core reduction was the production of a few late stage flake blanks, most likely for unmodified flake tools and potentially bifaces. Selection of metavolcanic nodule core toolstone, nodule core platform preparation, nodule core decortication and manufacture, and extensive nodule core reduction did not occur at this site. Only late stage flake blanks were produced at this location. Quartz, chert, and obsidian flakes also support this technological observation conceming metavolcanic nodule core reduction. Based upon the analyzed debitage sample from CA-SDI-8303, flintknapping activities were limited to nodule core flake blank production; minimal thinning and shaping by percussion and pressure flaking of small bifaces; resharpening of adzes that may have been laterally cycled from exhausted flake cores; and, resharpening of manos and metates with battered implements that may have also been laterally cycled from exhausted nodule and Topaz Mountain flake cores. PJ. 4-04 3-28 August 2005 3.5 FORMED ARTIFACT ANALYSIS (by Tracy Stropes and Jeff Flenniken) 3.5.1 Points and Bifaces A total of 17 bifaces were recovered from the indexing sttidy at CA-SDI-8303 (Table 3-10 and Figure 3-3). This sample includes nine complete or nearly complete specimens and eight fragmentary specimens. Their shape, size, and weight (see Table 3-10) indicate that nine ofthe specimens recovered are arrow points (Fenenga 1954) or arrow point fragments. The remaining eight specimens may be fragments of bifacial cores or bifacial knives that broke during use and/or manufacture, bifacial flake blanks, and/or preforms. Complete, but exhausted arrow points, in addition to broken arrow points (proximal ends and distal ends), were deposited into the archaeological context at CA-SDI-8303. This discard behavior most likely represents activities associated with retooling of bow/arrow hunting equipment. Broken arrow points were disposed of and replaced with new arrow points manufactured on site. The artifacts and debitage recovered sfrongly support this interpretation. Even the small nondiagnostic pressure-flaked biface fragments were most likely fragments of arrow points. Interestingly, site activities conceming the flaked stone artifacts were associated with arrow point manufacture and replacement, and only minimally with arrow shaft production, as fragments of arrow shaft sfraighteners and abraders were not present although flake tools, and/or scrapers were minimally identified in this assemblage. Arrow points from CA-SDI-8303 (and arrow points overall) are temporally sensitive, based on the weapon they were used with in conjunction with the bow and arrow. The aflatl and dart were replaced by the bow and arrow an estimated 1,500 years ago in San Diego County (Moratto 1984). This change required a transition to smaller projectile points suggesting that the site that these points originate from is less than 1,500 years old. Of the 17 bifaces, 9 are identifiable to the Cottonwood Series, and the remaining 8 are too fragmentary or exhibit too much damage to accurately place them within a relevant projectile point series. For the Cottonwood projectile points, four display concave bases in addition to concave margins, four maintain concave bases with relatively sfraight margins, and one maintains a concave base with convex margins. One of the nine specimens also displays evidence of serration, likely for PJ. 4-04 3-29 August2005 Table 3-10 Bifaces Recovered from CA-SDI-8303 Cat.

In addition, four of the specimens maintain remnants of their original detachment scar indicating manufacture directly from flake blanks. The two arrow point preforms or blanks (specimens CA-SDI-8303-154, and -250) were likely discarded because of problems encountered during manufacture, or to inherent problems with the material being worked. The presence of arrow point blanks in the CA-SDI-8303 assemblage, and several other small percussion flaked bifaces and fragments support Stage 3 debitage. These arrow point blanks were manufactured into preforms by pressure flaking the blanks. The presence of blanks and performs also supports on-site production of arrow points. Five ofthe projectile specimens display evidence of direct impact to the tip, likely from use. Each of these specimens (CA-SDI-8303-11, -82, -106, -147, and -249) maintains only minor damage in the form of tip flutes or a bending fractiire. It is possible that the damage incurred by these points was too severe, and as a result, the points were discarded. These pattems of breakage are indicative of direct impact to an opposing surface, possibly in a hunting situation (Woods 1987). One ofthe specimens (CA-SDI-8303-198) exhibits a manufactiaring error in the form of perverse fractiare. A perverse fractiire is defmed by Crabtree (1972) as "a helical, spiral or twisting break initiated at the edge of an objective piece." The perverse fracture on this projectile point likely occurred while pressure flaking along one of the lateral margins of the objective piece. Fractures of this type are common in both the archaeological record and in replicative experiments conducted throughout the past few decades (Woods 1988). Experimental data conceming the fracture pattems and rejuvenation of projectile points employed in simulated hunting situations are well established in the archaeological literature (Flenniken 1985; Flenniken and Raymond 1986; Titinus and Woods 1986; Towner and Warburton 1990; Woods 1988). Excavation of CA-SDI-8303 produced 13 arrow points, arrow point fragments, and small pieces of pressure flaked bifaces that may have been portions of arrow points. The biface assemblage and technological analysis indicates that reusable arrow points were rejuvenated, as badly broken arrow points were discarded and replaced with newly-made arrow points on site. Arrow points, point fragments, and debitage were recovered from 0-70 cm in depth from all units excavated. PJ. 4-04 3-32 August 2005 In addition to these complete points and point bases, three point tips and one mid-section were recovered. The specific point fragments recovered from the site display impact damage that may be indicative of hunting activities. Often, projectile points were broken on impact with inanimate objects (missed targets), or inside of animals (Flenniken 1985). Because of their small, unusable condition, tips and mid-sections were not retrieved, and therefore, may have remained at kill sites. Altematively, these fragments may have been deposited at the butchering location where the fragments were retumed in the dispatched animals. Additionally, these arrow point fragments may have been the results of flintknapping errors.that occurred during arrow point manufacture. The arrow point rejuvenation that occurred at the site resutted in the replacement and discard of five exhausted, but more or less complete, points. Exhausted points are those that have been slightly broken for the last time in their use-lives during hunting activities. Furthermore, as a result ofthe refurbishment ofthe hunting toolkit, arrow point bases broken in the haft (Flenniken and Raymond 1986; Flenniken 1985) were discarded and replaced with functional points. Basal fragments adhering to the foreshaft after being broken were frequentiy retrieved from kill locations because of the potential reuse ofthe point and the foreshaft. For the entire assemblage of arrow points and fragments recovered from the site, the ratio of complete points/bases to tips/mid-sections was nearly two to one. This technological observation suggests possible circumstances that relate to site function. First, frequently, bases and complete points were indicative of rejuvenation and weapon repair, while tips and mid-sections were indicative of hunting activities. If this scenario is trae for CA-SDI-8303, then the site is associated with a kill site wherein game was hunted. The actual kill site may be near CA-SDI-8303, or a minimal distance away. Given that faunal remains are somewhat extensive at CA-SDI-8303, the actual kill site most likely is a short distance away, \yherein the game was dispatched and butchered, with a large portion of the meat package being fransported back to CA-SDI-8303. Some small fragments of arrow points would have been brought back to the site in the meat package. Once back at CA-SDI-8303, the hunters repaired their broken, but reusable, arrow point bases brought back to the site on arrow shafts, and discarded badly broken and exhausted arrow points, and replacuig them with new arrow points made at the site. PJ.4-04 3-33 August 2005 3.5.2 Cores Three cores were recovered from CA-SDI-8303. All three cores represent unidirectional nodule core reduction, lack cortex, and were quite small (smaller than fist size). This suggests that the cores had become too small for further reduction, and/or recycling into another tool form (i.e., SEUT or battered implement). The presence of these cores further supports nodule core reduction activities at CA-SDI-8303. 3.5.3 Utilized Flake Tools Utilized flakes are flakes with a minimal amount or no shaping with modification (if any) generally restricted to the working edge, and often resulting from naturally occurring use-wear. These tools are frequently used for a short period of time, and then discarded. A total of six flake tools/flake tool fragments were identified in the present collection. Four of the six flake tools are laterally utilized flakes. Laterally utilized flake tools exhibit use or modification along a single lateral margin ofthe flake from which the tools were produced. In addition, small areas of polish are exhibited on natural arrises oh the flake tools suggesting use in a scraping activity. The four specimens maintain relatively sfraight edges. The angle of the working faces of the specimens are relatively low (less than 45 degrees). It is likely that these flake tools were used in a scraping motion for various purposes, including the working of opposing curved surfaces (such as vegetable products), animal materials (such as animal hides), and even other softer stone. In addition, two unaltered metavolcanic flake fragments (produced from nodule core reduction) were identified as tools during this analysis. Both fragments exhibited small areas of polish on natural arrises suggesting that these unmodified flake fragments were used to perform an activity that involved scraping with an obtuse edge. 3.5.4 Steep-Edged Unifacial Tools (SEUTs) Southem Califomia archaeology has recovered numerous amorphous lumps of metavolcanic stone that possess steep, unifacial edges for years. These objects have long been recognized by archaeologists as artifacts. However, these steep-edged unifacial tools, or SEUTs, have been subjected to numerous morphological and functional categories (i.e., horse hoof scraper, scraper plane, flake. scraper, biscuit scraper, various core types, etc.). Schroth's (1997) analysis of PJ. 4-04 3-34 August 2005 flaked stone tools from CA-SDI-11424 is by far the best effort to sort these artifacts into techno- fimctional categories. The category of adze, or woodworking tool, defines these tools. Three SEUTs and two flakes from SEUTs (adzes) were recovered from CA-SDI-8303. SEUTs are plano-convex in cross-section, have steep sides, are almost circular in planview, are heavy, and most importantly, have sfrong acute cutting edges. These tools are ideal woodworking tools because they are often sharp, weighted, and durable. Brian Hayden's (1979) ethnographic study in Austtalia, Palaeolithic Reflections, describes the manufacture and use of SEUTs by Austtalia's indigenous people in great detail. Given that the environments of Austtalia and southem Califomia are very similar, and that tools for woodworking were essential aspects of the prehistoric tool kit, southem Califomia SEUTs were most likely used in a similar manner. This functional interpretation is supported by the fact that these two tool categories are the same in terms of manufacture, material quality, size, shape, wear-pattems, and overall variation. Additionally, experimentation described by Schroth (1997) supports the use of SEUTs as adzes. Morphological variation within the SEUT category is, perhaps, the main reason for the numerous scraper, plane, etc., categories. However, this variation in size and weight was a technological consideration for the various tasks required of these tools. With basically the same attributes, except size and weight, these tools functioned as adzes, with different sizes and weights being essential for different tasks at hand. The most critical attribute, in addition to size and weight, was the acute, sharp cutting edge. When this edge became dulled during woodworking, the tool was resharpened or rejuvenated by removing flakes from the steep face while employing the piano-surface as a platform. These flakes are diagnostic, and were identified at CA-SDI-8303. The three SEUTs and two flakes from SEUTs identified in the present collection are very similar to other known SEUT/adze specimens recovered from sites such as CA-SDI-12814 (Gallegos et. al 2001), and CA-SDI-5581 (Gallegos and Sfropes 1999). However, the specimens from CA-SDI- 8303 are considerably smaller than the average SEUT/adze specimen. The present size of the PJ.4-04 3-35 August 2005 specimens may be a reflection of use-life termination, and not the ideal tool size and form. The specimens exhibit primarily unifacial use-wear, with a minimal amount of grinding visible on the ventral surface. The small size of these tools may indicate more confroUed tool functions such as specified scraping tasks ranging from fiber processing to the shaping of bone or wood artifacts. 3.5.5 Battered Implements Ten battered implements and eighteen battered implement flakes were examined during this analysis. These artifacts support a ground stone technology in association with the flaked stone technology at CA-SDI-8303. Prehistoric flaked stone assemblages from southem Califomia, Utah, Nevada, and the American Southwest contain a common artifact identified by archaeologists by a variety of names including chopper, hammerstone, pounder, muller, milling stone, flaked hammerstone, handstone, battered hammerstone, masher, basher, utilized core, scraper planes, pecking stone, fist ax, hand ax (Dodd 1979; Wallace 1978). Many of these artifacts are employed as archaeological identifiers of specific prehistoric cultiires (Wallace 1954; Kowta 1969). Others are simply weighed, measured, and described generally as plant and animal resource processing tools. Dodd (1979) and others (Ambler 1985; Geib 1986), however, have devoted considerable time and energy to the identification and function of a rather unsophisticated but highly specialized and important prehistoric tool class, battered hammerstones. Battered hammerstones are separated from the other artifact classes on the basis of pock marks located on one or more intentionally prepared areas on a single tool that are a result of repeated pounding against another hard object. These implements are most frequently produced from conchoidal fracturing, subrounded to subangular, spherical to discoidal, cobble-sized, quartzite, chert, metavolcanic, and volcanic nodular alluvial materials. The manufactiiring process includes the selection of a check-free rock (or, most likely at CA-SDI- 8303, an exhausted nodule core) of the appropriate material and size. After material selection, a unifacial or bifacial sinuous edge (or platform edge on a flake core) was produced by direct free hand percussion. The sinuous edge may have been situated on the side ofthe nodule, end ofthe nodule, or completely surrounding the nodule. The debitage produced as a result of edge PJ. 4-04 3-36 August 2005 manufactiire is characteristic of initial nodule reduction, but is not well-pattemed because ofthe variation in size, shape, and quality of the selected cobble. Because a sinuous edge was the "intended end product," general debitage characteristics may include cortex (in varying amounts) on the dorsal surfaces and platforms, few dorsal surface arrises, hinge terminations, thick flake cross- sections, angular flake planviews, single-faceted platforms, and more rarely, multi-faceted platforms. Once the sinuous edges were produced to satisfaction, the linear-edged hammerstone was ready for use. The use of these hammerstones produced battered edges: the longer the use, the more intense the battering. At some time during the use process, the battered hammerstone required resharpening. Resharpening included the removal of flakes by direct free hand percussion along the sinuous margin until the battered edge surfaces were partially or totally eliminated. A portion of the debitage produced during the resharpening process is very distinctive in that the battered edge that was once on the hammerstone is present on the proximal end of the dorsal surface of the resharpening flake (battered implement flakes, 1005.AZ Flake). Additionally,' some battered implement flakes (1005.AZ Flake) are produced during use (from block [battered implement] on block [metate]). However, flakes that do not exhibit battering on their dorsal surface were also produced, and are impossible to assign to the resharpening process. Once again, the hammerstone was ready for use. After numerous use/resharpening events, battered tools were discarded into the archaeological context. These discarded battered implements occur as exhausted, well-wom, intensely battered tools, or as resharpened, sharp-edged, small hammerstones with isolated areas of intense battering on one or more previously used margins. The latter were discarded because they were too small and lack the specific gravity to fimction efficiently. Experimental (Flenniken et al. 1993) and ethnographic data (Bartlett 1933; Hayden and Nelson 1981; Hill 1982; Hough 1897; Lange 1959; Michelsen 1967; Simpson 1952) document ground stone tools, mainly manos and metates, were manufactured, sharpened, and resharpened with battered implements (Flenniken et al. 1993). The sample of ten battered implements and eighteen battered implement flakes demonsfrates that manos and/or metates were resharpened at CA-SDI-8303. PJ. 4-04 3-37 August 2005 3.6 GROUND LiTHic ARTIFACT ANALYSIS 3.6.1 Introduction All ground stone materials recovered from CA-SDI-8303 were selected for analysis and interpretation. Ground stone implements may include a wide range of objects used, or created by the processes of abrasion, impaction, or polishing (Adams 2002). Often, ground stone tools are associated with the processing/milling of seeds, nuts (i.e., acoms, walnuts, holly leaf cherry), and the processing of small mammals. In addition, ethnographic evidence indicates that bone, clay, and pigments may have also been processed using the same tools (Gayton 1929; Kroeber 1925; Spier 1978). Implements of this type may be identified by the pattern of wear developed through milling stone against stone. This process often results in a smooth and/or polished surface, depending on the substance ground and the lithic material type. Often these surfaces are pecked or resharpened when ground too smooth. These implements are sometimes shaped into a desired form through pecking, grinding, or flaking. Thus, tool identification is based on the presence of ground or smooth surfaces, pecked or resharpened surfaces, and evidence of shaping of the tool form. The tools were separated into three groups: manos/metates, unidentifiable ground stone fragments, and battered implements. Unidentifiable ground stone is defined herein as a fragment of lithic material with a minimum of a single ground surface, but with no technologically identifiable characteristics to indicate tool form. 3.6.2 Manos A total of nineteen manos were recovered as a result of the indexing study at CA-SDI-8303. Ofthe total, eight were complete, or nearly complete, and eleven were fragmentary. The majority of manos recovered are granitic cobbles (n=l 5), followed by cobble volcanics (n=3), and quartzite (n=l) with bifacial use-wear (n=10) predominating the collection. Seven manos recovered at CA-SDI-8303 show evidence of shaping, such as pecking, flaking, and end-battering suggesting extended use. This extended usage and mano curation may imply long-term occupation of the site. There is end- battering present on one of the specimens, and two exhibit pecked grinding surfaces. The end- battering visible on the specimens may indicate that the manos were also used as hammers to sharpen metate grinding surfaces when they became too slick to grind. The overall curvature of each mano face is slight, indicating that the opposing milling surface that the manos were ground against PJ.4-04 3-38 August 2005 (i.e., metate, milling slick) was shallow in form. In addition, the grinding pattems evident on the faces of each mano indicate that the majority of manos are basin manos used primarily in a reciprocal sfroke manner in concert with shallow basin metates (Adams 2002). All ofthe manos collected were thermally damaged to varied degrees. It is possible however, that some ofthe manos present were not used for grinding purposes, but gleaned from other sites by the inhabitants of CA- SDI-8303 for use in rock hearth/earth ovens, or that the manos from CA-SDI-8303 were recycled at the site. In general, the ratio of manos to metates at a site where milling technology is present is much greater. It has been suggested that the reason for this is that manos wear out much faster than metates (Wright 1993), and thus more manos are produced as needed. The larger milling assemblage recovered from CA-SDI-8303 suggests that the inhabitants ofthe site depended on food packages that required milling for processing (i.e., grass seeds). It is evident that a large portion of the diet of the inhabitants of CA-SDI-8303 was derived from plant foods that required milling technology for consumption. 3.6.3 Metates Metates were identified based on the presence of at least one concave ground surface. Only block style basin metates were identified within the present collection. In total, five metates/metate fragments were recovered from CA-SDI-8303, and include three granitic and two sandstone specimens. Slab metates in comparison to block metates may be considered portable. Block metates are too heavy to transport and are defined by Binford (1980) as "site fumiture." The presence of these large block metates may be evident of a longer period of site occupation. The five metates are block metates, and include four unifacial and one unknown. The majority of the specimens retain shallow to flat grinding surfaces. The flat basins retain a more planer grinding surface, and may have been used to process less oily products such as fibers (Kowta 1969), whereas the shallow basins may have been used for the processing of products such as hard seeds. Basin morphologies identified for the metates recovered suggest primarily a reciprocal stroke pattem. All five ofthe specimens show evidence of pecking to rejuvenate the grinding surfaces. Two oftlie five metates display evidence of shaping in the form of pecking, flaking, and or grinding generally around the PJ. 4-04 3-39 August 2005 outer circumference. Flaking and pecking would have acted to remove unnecessary mass, and aid in producing the desired shape. Final grinding may have helped to even the overall surface, but was not always necessary. Three of the metate fragments recovered are thermally damaged. 3.6.4 Ground Stone Fragment Six ground stone fragments were identified in the present collection. A ground stone fragment is a piece of ground stone implement that has some grinding, but lacks any defining attributes that would facilitate tool identification. The small fragments recovered from CA-SDI-8303 are all granitic and thermally damaged. 3.6.5 Polished Stone A fragment of polished stone was also recovered from excavations at CA-SDI-8303. Specimen CA- SDI-8303-248 is semi-round in form and exhibits polish around the circumference. The volcanic specimen measures 92.2x45.1x36.9 mm with a weight of 192.7 g. The use of the artifact is unknown. However, the polish on the high portions of the artifact and its granular stincture suggest it may have been employed in lapidary applications. 3.7 CERAMIC ANALYSIS (by Monica Guerrero) 3.7.1 Introduction As a result of the current study, a total of449 ceramic sherds were recovered from CA-SDI-8303. All sherds were not included in the ceramic analysis, as some sherds were too small to obtain a thin- section sample. A total of 289 sherds from CA-SDI-8303 were included for sample selection. Ceramic sherds were first placed into different sample groups based upon mica (biotite and muscovite) concentration, sherd thickness, rim shape variability, surface color, and core color. Sherds with recent broken edges were checked to see if they mended with other sherds within the sample group. Both procedures reduced the possibility of analyzing sherds from the same parent vessel. At site CA-SDI-8303,11 different sample groups were identified. After all the sherds had PJ. 4-04 3-40 August 2005 been placed into different sample groups, each group was placed into plastic bags and a random sherd was selected as the representative sample for each group. Eleven ceramic sherds from CA-SDI-8303 were submitted to the San Diego Pettographics Laboratory, in Escondido, Califomia, for the creation of thin-section samples. Each sherd was enveloped in epoxy resin, then polished and cemented to a glass slide. The sample was then cut and polished to a thickness of 30 microns (pm), and sealed with a glass-cover slip. Once the thin-section samples, along with what remained of the ceramic sherds, were retumed to Gallegos & Associates laboratory, they were analyzed for mineral composition. Each thin-section sample was examined under a polarizing (pettographic) microscope by ttansmitted light (plane-polar and cross-polar) from 28X to 1500X magnifications. Important mineral characteristics considered when examining the thin sections include distinctive cleavage, twinning, alteration, zoning, exsolution, or the presence of inclusions. For a discussion of ceramic wares in the San Diego region see Section 2.5.2.1. 3.7.2 Results A total of 449 ceramic sherds were recovered during the index sampling of site CA-SDI-8303. However, only 289 sherds were included in the study sample, as a good portion of the ceramic collection was highly fragmented, and ranged from less than 1 cm in length. No rim sherds were analyzed, as they were too small to provide data on the orientation of the vessel mouth or radius of the vessel opening. A representative sample of ceramic sherds from site CA-SDI-8303 were thin- sectioned, and analyzed under a polarizing (pettographic) microscope to identify specific mineral inclusions and their corresponding geologic locales. Pettographic thin-section analysis was conducted on 11 ceramic sherds. Results of this analysis indicate that 98% (n = 284) of these sherds are Tizon Brown Ware, and 1% (n = 5) are Lower Colorado Buff Ware (Table 3-11). There are no Salton Brown Ware ceramics present in this sample.

As site CA-SDI-8303 is located in a coastal area, trade and/or travel inland, and/or to mountain regions occurred for procurement of mountain clays. 3.8 SHELL ARTIFACT ANALYSIS (by Tracy Sfropes) 3.8.1 Introduction For San Diego County, a processual understanding of manufacture, distribution, and use of shell artifacts has not been achieved. In addition, the range of morphological types of beads used in the San Diego region is not well understood. In contrast to other regions of California, there is little information conceming the process by which shell artifacts were manufactured and used, or the evolutionary changes these artifacts may have gone through over time. The analysis of shell artifacts from other regions of Califomia (most notably the Chumash culture area) has demonsfrated considerable anthropological value in the understanding of prehistoric economies, frade systems and networks, and the organization of wealth and status in prehistoric societies (Fenenga 1988). For these regions, particular styles of shell artifacts have been established as chronologically diagnostic in a number of archaeological sites. The shell artifact assemblage from CA-SDI-8303 is large in comparison to many sites in the north San Diego region. Although the present data will not answer some of the larger questions that may be resolved by a greater regional study of multiple archaeological sites, it will certainly contribute to the presently limited body of data, and will be of value to future research issues regarding shell artifacts. The shell artifacts for the present analysis were recovered across the five units within the midden deposit of CA-SDI-8303. The use of 1/8"* inch hardware mesh screen, in addition to the wet screening of the recovered midden, likely increased the recovery of shell artifacts. The use of larger screen sizes can often bias the recovery of specific small bead types, possibly removing them from the assemblage altogether. It should also be noted that none of the present specimens included in the analysis were identified in context with any identifiable cultural features, and appear to be randomly distributed across the site. However, "scattered, isolated beads often are found in and around living areas of aboriginal villages in Califomia." (Fenenga 1988). PJ. 4-04 3-43 August 2005 For this analysis, the typology developed by Gifford (1947) will be employed. A total of twenty shell artifacts were recovered as a result of the indexing study at CA-SDI-8303. The majority of the . specimens (n=12) are beads made from the shells of Olivella biplicata, a relatively small marine gasfropod. Seven of the shell beads are disc beads manufactured from the central (thicker) portion of a bivalve. Based on the large quantities of Chione sp. recovered from the site, this is the likely species from which these beads were manufactured. In addition, a single Cypraea spadicea Swainson (Chestnut Cowry) shell was recovered from the site.» . 3.8.2 Olivella sp. Shell Beads Of the 12 Gifford type F5 Olivella sp. shell beads (Figure 3-4) two primary manufacturing techniques are present, spire-lopped and spire-ground. Although these two manufacturing techniques have often been split into separate types by various archaeologists (Bennyhoff and Heizer 1958; Bennyhoff and Fredrickson 1967; King 1982; Gibson 1974; Bass and Andrews 1977; Bennyhoff 1986; Bennyhoff and Hughes 1987), it is more likely that the difference in techniques utilized is a matter of manufacturing preference rather than stylistic change. This hypothesis is supported by the fact that the two manufacturing techniques often occur at the same time within the same assemblage. These specimens are primarily whole shells that have the spire end modified by breaking or grinding to produce a hole for sfringing or attaching. These are the simplest and most easily produced form of shell bead. In general whole Olivella sp. beads are not considered to be reliable time markers throughout Califomia. However, spire-lopped/ground Olivella sp. beads are likely the oldest form of shell bead known from Califomia (Fenenga 1988). Evidence from CA- SDI-1 1079 in Otay Mesa suggests the employment of Olivella sp. shell for beads as early as 9,000 years ago (Kyle et al. 1998) and ethnographic evidence demonsfrates that their use continued throughout historic times (Howard 1974; Dietz and Jackson 1981; Roop and Flyrm 1978). 3.8.3 SheU Disc Beads A total of seven shell disc beads (Gifford Type J, likely Jlc) were recovered from excavations at CA-SDI-8303 (Figure 3-5). The majority ofthe beads were likely produced from Chione sp. shell found in relative abundance within the site midden. In addition, they were likely manufactured in a similar manner. The shape was likely cut from a bivalve utilizing no natural edges, ground into PJ.4-04 3-44 August 2005 CA-SDI-8303-60 CA-SDI-8303-194 CA-SDI-8303-54 CA-SDI-8303-105 CA-SDI-8303-67 CA-SDI-8303-153 CA-SDI-8303-103 CA-SDI-8303-22 CA-SDI-8303-130 CA-SDI-8303-15 CA-SDI-8303-236 Gallegos & Associates 3 cm Olivella sp.

This type of bead clearly requires a greater investment oftime and energy to produce. It is not clear if there is any temporal difference between the Type F5 Olivella sp. shell specimens identified at CA-SDI-8303, or the Type J disc bead specimens. 3.8.4 Cypraea spadicea Swainson (Chestnut Cowry) A single Chestnut Cowry shell specimen was recovered from the 40-50-cm level of Unit 7. Although no evidence of drilling or residues for attachment of the specimen as an idiotechnic object is apparent, cowry shells still remain uncommon in the archaeological assemblages of southem Califomia. Therefore the presence of such specimens within assemblages should be noted. Although the use of the present specimen is uncertain, it should be noted that cowry shells cross- culturally have been identified in relation to a variety of special powers and symbolic content (Koerper and Desautels 1999). This symbolic content ranges from conceptions about the "evil eye" to fecundity-based symbolism. For prehistoric southem Califomia, it has been suggested that evidence exists to support the hypothesis that cowry shells are tied to sex-based symbolism (Koerper and Desautels 1999). 3.9 MISCELLANEOUS ARTIFACT ANALYSIS 3.9.1 Introduction Miscellaneous artifacts represent cultural material that is set apart from any of the major analysis categories identified at a given site. For CA-SDI-8303, these artifacts include a small range of artifact types including one quartz crystal, two glass ttade beads, and a fragment of pine pitch. Descriptions and analyses of the miscellaneous artifacts recovered from CA-SDI-8303 are provided below. 3.9.2 Quartz Crystal A single quartz crystal (specimen CA-SDI-8303-91) was recovered from the 50-60-cm level of Unit 6 at CA-SDI-8303. The quartz crystal specimen is relatively small (<10 mm in length) and displays no evidence of hafting. Many quartz crystals were thought to have magical powers (Sparkman 1908), and were ethnohistorically known to be hafted on the ends of ornate wooden, wand-like PJ. 4-04 3-47 August 2005 objects known as shamans' wands as described by Kroeber (1925). However, because ofthe small size of specimen CA-SDI-8303-91, it is unlikely that this fragment of quartz crystal sensed such a function. The use of specimen CA-SDI-8303-91 is undetermined. 3.9.3 Glass Trade Beads Two glass frade beads were identified in the artifact assemblage from CA-SDI-8303. Glass frade beads were employed by the Spanish primarily for trade and commerce during tiie mission period in Califomia history. The glass frade beads, predominantly manufactured in Venice, Italy, were often used as currency to compensate Native American laborers for work performed at the missions, such as nearby Mission San Luis Rey (San Diego Historical Society 2005). Specimen CA-SDI-8303-146, recovered from the 10-20-cm level of Unit 9, is a dark red cane bead. Specimen CA-SDI-8303-193, recovered from the 40-50-cm level of Unit 7, is a copper green cane bead. Copper blue, cobalt blue, and copper green cane beads are identified as the most common glass frade beads exchanged in southem Califomia (San Diego Historical Society 2005). The presence of glass frade beads at CA- SDI-8303 suggests that the inhabitants of the site had contact with the Spanish or with other missionized Native Americans. Additionally, the presence of glass frade beads at CA-SDI-8303 supports a Late Period component at the site. 3.9.4 Pitch A single fragment of pitch (likely pine) was recovered from excavations at CA-SDI-8303. The specimen (CA-SDI-8303-133) was collected from the 20-30-cm level of Unit 11. Pitch was used prehistorically for a range of applications that include waterproofing, as mastic, and for medicinal purposes. The fragment of pitch recovered from CA-SDI-8303 is small (<1 gram), and represents the only specimen recovered from both current and previous excavations at the site. 3.10 INVERTEBRATE FAUNAL ANALYSIS 3.10.1 Introduction Invertebrate remains recovered from the excavation of six Ixl-m units at CA-SDI-8303 totaled 32,838.1 g. All shell recovered from the site was identified to species, order, and class. A total of PJ. 4-04 3-48 August 2005 I I I 1 I I I I I 12 species, 4 orders, and 3 classes of invertebrate remains were identified for the six units. These shellfish species were representative of three marine environments: bay/lagoon/estuary; rocky shore/outer coast; and sandy beach. 3.10.2 Methods Each shell was weighed and examined to identify genus and species. All shell was speciated in order to determine habitat exploitation pattems and to obtain paleo-environmental data. 3.10.3 Results The 32,838.1 g of invertebrate remains recovered by unit are as follows: Unit 7 (10,254.7 g); Unit 11 (9,865.9 g); Unit 8 (5,454.7 g); Unit 9 (4,820.1 g); Unit 6 (2,277.5 g); and Unit 10 (165.2 g). Table 3-12 illusttates that the majority of shell was recovered from the upper (0-50 cm) levels and declined with greater depth of excavation. Ofthe 32,838.1 g of shell recovered, 32,078.2 g were identifiable to species. The remaining 759.9 g were determined to be too fragmentary or weathered for proper identification. Table 3-13 lists the species identified and their habitats. The majority of invertebrate remains were gathered from the sandy beach environmient (71.6%), followed by a bay/lagoon/estiiary environment (28.3%)), and a small amount from the rocky shore/outer coast environment (0.1%)(Figure 3-6). Given the shell species recovered, the focus of exploitation of the native inhabitants of CA-SDI-8303 was primarily on sandy beach environments, followed by bay/lagoon/estiiary environments. The radiocarbon dates suggest that this exploitation pattem may represent different time periods of occupation for CA-SDI- 8303. Table 3-13 illusttates that the majority of the identifiable shellfish species recovered from the 6 units were Donax gouldii (71.6%), Chione sp. (24.8%)), and Argopecten sp. (2.7%o)(Figure 3-7). The remaining species from the site contributed to less than one percent of the total specimens. This indicates a primary exploitation focus on sandy beach habitats for the inhabitants of CA-SDI-8303.

However, there is some evidence of exploitation of bay/lagoon/estuary habitats as well. It is uncertain if this exploitation pattem represents a focus on two environments at the same time, or the focus on different environments during different occupations. The radiocarbon dates support exploitation of different environments at different times. In addition, a sizeable sheU bead assemblage was identified at CA-SDI-8303. Although the assemblage was culled to identify the presence of shell bead manufacture detritus, no manufacturing debris was identified. Given the results of shellfish analysis for CA-SDI-8303, the inhabitants likely exploited the nearest sandy beach habitat (likely near present day South Carlsbad State Beach) during the Late Period, and nearest bay/lagoon/estuary habitat (Agua Hedionda Lagoon) during the Early Period. 3.11 VERTEBRATE FAUNAL ANALYSIS (by Patticia Mitchell) 3.11.1 Introduction The bird, mammal, reptile, and fish bone collection from site CA-SDI-8303 consists of 6,574 fragments with a combined weight of465.4 g. Of the 6,574 fragments, 7 (0.7 g) were determined to be intrusive to the prehistoric site. These seven bone fragments exhibit signs of intrasiveness such as oily texture, or fragile, whole elements. The oily texture suggests the presence of collagen in the bone, and therefore, the bones are most likely the result of a recent, natural death, and were not included in the following data tabulations. The remaining 6,567 (464.7 g) bone fragments were recovered from the 0-90-cm levels of five excavation units within the primary site area (Units 6, 7, 8,9, and 11). All bone fragments were identified to class, order, family, or when possible to genus and species. Nineteen animal species were identified and two additional genera. The animals identified to genus and species include Callipepla califomica (Califomia quail), Canis latrans (coyote), Clemmys marmorata (southwestem pond turtle), Galeorhinus zyopterus (soupfin shark), Genyonemus lineatus (white croaker), Lepus califomicus (black-tailed jackrabbit), Myliobatis califomica (bat ray), Odocoileus hemionus (mule deer), Paralichthys califomicus (Califomia halibut), Rhinobatos productus (shovelnose guitarfish), Roncador steamsii (spotfin croaker), Sardinops sagax (Pacific sardine). Scomber japohicus (Pacific mackerel), Semicossyphus pulcher PJ. 4-04 3-54 August 2005 (Califomia sheephead), Spermophilus beecheyi (Califomia ground squirrel), Sylvilagus audubonii (desert cottontail), Sylvilagus bachmani (brash rabbit), Thomomys bottae (Botta's gopher), and Thunnus alalunga (albacore). The two genera identified are Embiotoca sp. (surfjperch) and Sebastes sp. (rockfish). The remaining bone fragments lacked the morphological featiires that would have allowed them to be identified to a taxonomic category greater than their class. Other categories used to identify these fragments include bird, elasmobranch, teleostei, ray, ray/skate, lizard, snake, marine mammal, small mammal, medium mammal, and large mammal. Evidence of buming was present on a portion of the collection and has allowed for some interpretation ofthe preparation of the meat portion of the inhabitants' diet at site CA-SDI-8303. Three bone artifacts were also recovered from the site and are discussed in Section 3.11.6. 3.11.2 Methods Each bone was examined to determine: • element • right or left side • highest taxonomic category • evidence of buming, and if so, what degree of oxidation • evidence of butchering, and if so, what method of butchering Comparative skeletal collections used in the identification process included those from Scripps Institute of Oceanography, as well as from private collections and a photographic database. Bone atiases (Carr 1952; Lawrence 1951; Nickel et al. 1986; Olsen 1985; Sandefur 1977; Schmid 1972) supplemented the analysis. Categories used in this analysis include: Bumed: Bone elements or fragments that show color change from exposure to heat or fire (oxidation). Colors may include: • brown = exposure to heat, but little or no exposure to open flames. • black = direct exposure to open flames (i.e., roasting or discard in a fire). PJ. 4-04 3-55 August 2005 • blue/white (calcined) = direct exposure to a fire hotter than 800° Celsius (Ubelaker 1978). This may represent bone that was severely bumed during preparation, in which case, if flesh was present on the bone during exposure to the fire the bone would exhibit signs of warping and shrinking (Ubelaker 1978). Calcined bone may also be the result of having been discarded in a fire hearth (Wing and Brown 1979). Unbumed: No evidence of buming or oxidation. Butchered: Bone with evidence of processing by slicing or chopping actions. Bird: Bones that have thin walls in cross-section, are hollow, and light in weight. These are often distinguishable from mammal bone because they contain large cavities that would have been filled with air in life. Lizard: Small animal bone fragments that are usually mandible fragments with homodont teeth that are sfraight instead of curved like snake teeth, or longbone fragments that are split and funnel-shaped or vertebrae with ball and socket features with a flattened vertebral foramen. Snake: Vertebrae with ball and socket features with a domed-shaped vertebral foramen. Small Mammal: All nondiagnostic vertebrate fragments, whose sizes are between a mouse and a jackrabbit. Medium Mammal: All nondiagnostic vertebrate fragments, whose sizes are larger than a jackrabbit, but smaller than a deer. Large Mammal: All nondiagnostic vertebrate fragments, whose sizes are deer-size and larger. Marine Mammal: Sea mammals' bones are often distinguished from other medium or large-sized terrestrial mammals by the spongy texture. Elasmobranch: Dram-shaped vertebra that are from cartilaginous fish (rays/skates, shark). Ray/Skate: Tooth plates that are from rays and skates, as well as spines and hooks. Teleostei: Funnel-shaped vertebrae with/without the spinous process attached, and other skeletal elements considered as bony fish. The quantification of faunal material can be studied using several methods. The methods used in individual studies are usually determined by the sample size and type of site being investigated. Two methods were used in this study: the number of identified specimens per taxon (NISP), which PJ. 4-04 3-56 August 2005 represents the total number of specimens within a category; and the minimum number of individuals (MNI), which represents the minimum number of individuals within a genus and species category. 3.11.3 Results The animal remains recovered from the five excavation units consisted of 6,567 (464.7 g) bone elements from the 0-90-cm levels of the site (Tables 3-14 and 3-15). Nineteen animal species and two genera were identified from 856 (13.0 %o) pieces of bone and include Callipepla califomica (Califomia quail), Canis latrans (coyote), Clemmys marmorata (southwestem pond turtle), Embiotoca sp. (surfperch), Galeorhinus zyopterus (soupfin shark), Genyonemus lineatus (white croaker), Lepus califomicus (black-tailed jackrabbit), Myliobatis califomica (bat my), Odocoileus hemionus (mule deer), Paralichthys califomicus (Califomia halibut), Rhinobatos productus (shovelnose guitarfish), Roncador steamsii (spotfin croaker), Sardinops sagax (Pacific sardine), Scomber japonicus (Pacific mackerel), Sebastes sp. (rockfish), Semicossyphus pulcher (Califomia sheephead), Spermophilus beecheyi (Califomia ground squirrel), Sylvilagus audubonii (desert cottontail), Sylvilagus bachmani (brash rabbit), Thomomys bottae (Botta's gopher), and Thunnus alalunga (albacore). The remaining 5,711 bone fragments lacked the morphological features that would have allowed them to be identified to the genus and species level, and were therefore identified as bird, elasmobranch, teleostei, ray, ray/skate, lizard, snake, marine mammal, small mammal, medium mammal, or large mammal. Horizontal distribution of NISP counts presented in Table 3-15 shows that the majority of bone elements were recovered from Unit 8 (30.0 %), followed by Units 11 (27.4 %), 7 (20.9 %), 9 (16.1 %), and 6 (5.5 %). Table 3-15 presents the results ofthe vertical distribution of NISP counts of the five units. There is a steady increase of vertebrate remains recovered from the surface to the 30-cm levels (NISP=711 to NISP=1,112). The NISP counts begin to decline from the. 30-cm level to the 90-cm level (NISP=1,112 to NISP=63). The majority of bone fragments (95.8 % combined) were recovered from the 0-70-cm levels, with the greatest concenfration in the 10-60-cm levels (76.2 %).

A minimum total of 49 animals were represented in the collection. The terrestrial small mammal species {Sylvilagus audubonii: MNI=8; Thomomys bottae: MNI=7; Sylvilagus bachmani: MNI=5; Lepus califomicus: MNI=3; and Spermophilus beecheyii: MNI=1) were the most abundant, and represented 24 (48.9%) ofthe 49 animals. The fish species were the second most abundant, and represented 21 (42.8%) ofthe 49 animals identified (Genyonemus lineatus: MNI=8; Sardinops sagax: MNI=5; and Galeorhinus zyopterus, Myliobatis califomica, Paralichthys califomicus, Rhinobatos productus, Roncador steamsii. Scomber japonicus, Semicossyphus pulcher, and Thunnus alalunga with a MNI=1 each). Reptile (Clemmys marmorata), terrestiial medium mammal (Canis latrans), and large mammal (Odocoileus hemionus) each had a MNI=1. Throughout the site, the greatest resource was small-sized mammals, and included Lepus califomicus, Spermophilus beecheyii, Sylvilagus audubonii, Sylvilagus bachmani, Thomomys bottae, and small mammal (80.0 %> combined). The remaining animal resources contiibuted much less to the meat diet at the site: fish resources were 16.7 %; large mammal resources were 2.8 %; medium mammal resources were 0.2 %; reptile, avian, and marine mammal resources were 0.1 %> each. Table 3-17 shows evidence that buming was present on the majority of the bone collection (69.4 %>). Ofthe 4,560 bones bumed, 90.3 %> (n=4,l 19) were bumed brown in color, indicating exposure to heat, but not to a direct flame. Additionally, these animals were likely cooked in some type of container (i.e., pottery, stone, basket). Dracker (1937) noted that the bones of small mammals and the meat were pulverized, and that heated stones were used in baskets for cooking (stone boiling) by the Luiseno Native Americans. Animal species or categories bumed brown in color include: Clemmys marmorata, Embiotoca sp., Galeorhinus zyopterus, Genyonemus lineatus, Lepus califomicus, Myliobatis califomica, Odocoileus hemionus, Paralichthys califomicus, Rhinobatos productus, Roncador steamsii, Sardinops sagax, Scomber japonicus, Sebastes sp., Semicossyphus pulcher, Spermophilus beecheyi, Sylvilagus audubonii, Sylvilagus bachmani, Thomomys bottae, Thunnus alalunga, ray/skate, elasmobranch, teleostei, snake, marine mammal, small mammal, medium mammal, and large mammal.

The coloring suggests that these bones were bumed during roasting, or that they were discarded in a fire hearth. Wing and Brown (1979) suggest that this type of charring is usually confined to the exposed ends of bone. This type of charring was only identified on one Lepus califomicus proximal radius bumed black in color. It is likely that the remaining specimens charred black were the result of being discarded in a fire hearth. Animal species or categories charred black in color include Lepus califomicus, Myliobatis califomica, Sardinops sagax, Semicossyphus pulcher, Sylvilagus audubonii, Sylvilagus bachmani, ray, elasmobranch, teleostei, small mammal, and large mammal. The specimens that were calcined (1.8 %), n=82 of the bumed elements) were exposed to a direct flame at exfremely high temperatures (greater than 800° Celsius), None of the calcined bones exhibited signs of shrinking or warping. These are attributes that indicate the presence of soft tissue on the bone at the time of exposure to an open flame. The calcined specimens were likely the result of being discarded in a fire hearth. Animal species or categories calcined include Myliobatis californica, Rhinobatos productus, Semicossyphus pulcher, Sylvilagus bachmani, elasmobranch, teleostei, small mammal, and large mammal. 3.11.4 Butchered Bone No butchering marks were observed on the bones in this collection. 3.11.5 Natural History Terrestrial There are three species of Leporidae represented in the vertebrate collection: Lepus califomicus (black-tailed jackrabbit), Sylvilagus audubonii (desert cottontail rabbit), and Sylvilagus bachmani (brash rabbit). Jackrabbit is found only in open or partially open areas (Bond 1977), and is most active in the moming and early evening. They feed on green vegetation, shrabs, and cacti (Russo and Oldhausen 1987). According to Christenson (1986), jackrabbit is best hunted with nets. Dracker (1937) also noted that rabbits were hunted in communal drives and driven into nets. Desert cottontail can be found in open plains, foothills, low valleys, and coastal areas, and are easily caught with a rabbit stick or bow and arrow (Christenson 1986). They are most active in early moming, late PJ. 4-04 3-63 August 2005 afternoon, and at night. Their diet consists of green vegetation and fniit (Russo and Oldhausen 1987). Brash rabbit can be found in areas of thick brash. It is primarily noctumal, and does not dig burrows. When pursued, the brash rabbit will more often go into low bmsh for protection rather' than retreat into another animal's burrow (Whitaker .1980). All three Leporidae were probably hunted for food as well as for their pelts (Schroth and Gallegos 1991). Two rodent species were identified in this collection, and both species are native to San Diego County. Spermophilus beecheyi (Califomia ground squirrel) and Thomomys bottae (Botta's pocket gopher) can be found in areas ranging from the mountains to the coast. The ground squirrel, like the gopher, is a burrowing animal. It is active from dawn until dusk, and while it may climb into brash or frees it usually remains on the ground. The gopher is the most common and widespread rodent, occurring wherever there is vegetation and loose dirt to burrow through (Bond 1977). Odocoileus hemionus (mule deer) is native to the westem half of the United States, most of Canada, and northem Mexico. It feeds on shrabs, twigs, grasses, and herbs in several types of habitats, such as coniferous forests, desert shrubs, chaparral, and grasslands with shrabs. Mule deer is most active in the moming and the evening, and occur singly or in small groups (Burt and Gossenheider 1976). Ethnographic data states that hunters would disguise themselves with the head and fur of a deer when stalking other deer (Ashby and Winterboume 1966; Christenson 1981), and the usual weapon used to kill deer was the bow and arrow, but the use of snares has also been documented (Sparkman 1908). The killed deer was useful for items such as the meat, hide, and hoof (for rattles). Canis latrans (coyote) is native to most of the United States (Booth 1950), and is found in San Diego County in the Upper and Lower Sonoran life-zones (Bond 1977). Coyotes are primarily noctumal, but can be active at any hour. Their dens are usually located along river banks, canyons, and gulches. They are omnivorous, but their diet consists mostly of small mammals (Russo and Olhausen 1987). Dracker noted that the Luiseno avoided eating coyote (1937), and the coyote bone recovered from the site is a claw so it is not certain that they actually consumed coyote at this site. • PJ. 4-04 3-64 August 2005 Avian Callipepla californica (Califomia quail) is a common resident in San Diego County and according to Unitt (1984), can be found in "broken chaparral, grassy edges of chaparral or woodland, orchards, and dense desert and semi-desert scrab." They are prevalent on the coastal slopes, and can also be found on the eastem slopes of mountains, as well as into the Anza-Borrego desert (Unitt 1984). Unitt (1984) documents definite breeding areas for Califomia quail occurring on Point Loma, and former breeding areas just east of Point Loma. Reptile Clemmys marmorata (southwestem pond turtle) once ranged from Monterey Bay to northem Baja Califomia, from coastal drainages to foothills, and even to the desert slope of the Mojave River (by the San Bernardino Mountains)(Bond 1977). The southwestem pond turtle hibemates through winter and emerges in March (Carr 1978). The diet ofthe southwestem pond turtle consists of aquatic plants, insects, and carrion (Schneider and Everson 1989). "Turtle" uses include meat consumption, ceremonial use (rattles), medicinal use, technological uses including ladles, scoops, bowls, and containers, and symbolic uses in Native American artwork and oral fraditions. Marine Fish Galeorhinus zypoterus (soupfin shark) is a common epipelagic shark along the Califomia coast. It ranges from San Juanico Bay in Baja Califomia to northem British Colombia. It can grow to 6.5 ft. in length (MUler and Lea 1972). Genyonemus lineatus (white croaker) is a common fish along the southem Califomia coast. It ranges from Magdalena Bay in Baja Califomia to Vancouver Island, B.C. (Miller and Lea 1972). It occupies all of the soft subsfrate habitats, but less so in the kelp beds and the deep rock reefs (Allen 1985). ^ Myliobatis californica (bat ray) is a common fish that can be found in bays and sandy shallow areas to a depth of 150 ft. anywhere from the Gulf of Califomia to Oregon (Miller and Lea 1972). It can weigh up to 210 lbs. and have a width of 4 ft. (Miller and Lea 1972). PJ. 4-04 3-65 August 2005 Paralichthys califomicus (Califomia halibut) is a common fish along the southem Califomia coast and can be found from the surface to 300 ft. in depth. It ranges from Magdalena Bay in Baja Califomia to the Quillayute River in British Columbia (Miller and Lea 1972). It can be found in harbor/nearshore soft bottom habitats, and to a lesser degree bay/estuary environs (Allen 1985). Rhinobatos productus (shovelnose guitarfish) is a common fish along the Califomia coast that ranges from the Gulf of Califomia to as far north as San Francisco, and can be found from the surface to a depth of 50 ft. (Miller a;nd Lea 1972). It can be found in harbor/nearshore soft bottom habitats, and to a lesser degree bay/estuary environs (Allen 1985). Roncador stearnsii (spotfin croaker) is a common fish along the southem Califomia coast. It ranges from Mazatlan, Mexico to Point Conception, and includes the Gulf of Califomia (Miller and Lea 1972). It occupies open coast sandy beach habitats with seasonal occurrences in the bay/estuary environment during the spring and summer (Allen 1985). Sarda chiliensis (Pacific bonito) is a common fish along the Califomia coast. It ranges from Chile to the Gulf of Alaska (Miller and Lea 1972). It is a neashore pelagic species that occupies midwater habitats including deeper rock reefs and kelp beds (Allen 1985). Sardinops sagax (Pacific sardine) and Scomber japonicus (Pacific mackerel) are both nearshore pelagic species, which are only found in nearshore midwater environments (Allen 1985). The sardine can be found along the Pacific coastline between Guaymas, Mexico, and Kamchatka, and grow to a length of 16 in. (Miller and Lea 1972). The mackerel can be found from Chile to the Gulf of Alaska, and grow to a length of 25 in. (Miller and Lea 1972). Semicossyphus pulcher (Califomia sheephead) can be found from Cape San Lucas in Baja Califomia to Monterey, Califomia. They can be 3 ft. long and weigh up to 36 lbs. They occur from the surface to 180 ft. (Miller and Lea 1972), and can be found in shallow and deeper rock reef and kelp bed environments (Allen 1985). PJ. 4-04 3-66 August 2005 Thunnus alalunga (albacore) is a common epipelagic fish along the Califomia coast. It ranges from Guadalupe Island to southeast Alaska. It can weigh as much as 93 lbs., but in Califomia only as much as 76 lbs. (MiUer and Lea 1972). 3.11.6 Bone Artifacts Three bone artifacts were recovered from the site. Gifford's 1940 publication was used to assign a typological category when possible. One bone awl fragment, a drilled fish vertebra, and a modified bone fragment were identified in the collection. Table 3-18 lists each artifact, its provenience, and type. Artifact CA-SDI-8303-49 was a tip fragment of an awl recovered from the 40-50-cm level of Unit 11, and assigned with Gifford's type Alal (1940). The tip fragment was manufactured from a mule deer cannon bone with the distal end used as the handle. It had been slightly bumed (light brown in color), shaped, with little polished near the tip (Figure 3-8). There was evidence of diagonal use- wear striations. Artifact CA-SDI-8303-55 was a biconically-drilled soupfin shark (Galeorhinus zyopterus) dorsal vertebra. It was recovered from the 50-60-cm level of Unit 11, and was assigned with Gifford's type CC5 (1940). The fragment was manufactured from shark vertebra, and had no Other modifications other than being drilled (see Figure 3-8). One other unmodified soupfin shark vertebra was recovered from a lower level ofthe same excavation unit. Artifact CA-SDI-8303-143 was a fragment of modified bone manufactured from a medium to large- sized mammal. It was recovered from the 10-20-cm level of Unit 9, but was not able to be assigned a Gifford typological category. The bone had been bumed (dark brown in color), frapezoid-shaped in cross-section, and polished (Figure 3-9). No use-wear striations were observed, and no function of the artifact could be ascertained.

Identification of the fish species was completed with the use ofthe fish collection at Scripps Institute of Oceanography in La Jolla, Califomia, which consists of450 Pacific coast and deepwater specimens. The otoliths were first weighed (in grams) and measured (in millimeters). The process for analysis includes encasing the otolith in a clear resin matrix, then cutting it in half with a lapidary saw and buming the cut surface to better define the incremental lines. The cut surface was then examined under a stereoscopic microscope at lOX and/or 20X. The seasons are defined as: spring=mid-March through mid-May; sunimer=mid-May through early-October; and winter=mid-October through mid- March. 3.12.2 Results The two otolith specimens were identified as Genyonemus lineatus (white croaker) and Roncador stearnsii (spotfin croaker), and represented fish captured during the summer. The otoliths were recovered from the 10-20-cm level of Unit 11 (Genyonemus lineatus), and the 60-70-cm level of Unit 7 (Roncador stearnsii)(2l^dib\Q 3-19). 3.12.3 Natural History Genyonemus lineatus (white croaker) is a common fish along the southem Califomia coast. It ranges from Magdalena Bay in Baja Califomia to Vancouver Island, B.C. (Miller and Lea 1972). It occupies all pf the soft subsfrate habitats, but less so in the kelp beds and the deep rock reefs (Allen 1985). Roncador steamsii (spotfin croaker) is a comnion fish along the southem Califomia coast. It ranges from Mazatlan, Mexico to Point Conception, and includes the Gulf of Califomia (Miller and Lea 1972). It occupies open coast sandy beach habitats with seasonal occurrences in the bay/estuary environment during the spring and summer (Allen 1985).

Specimen CA-SDI-8303-66A was collected from tiie 60-70- cm level of Unit 11, and is a Polinices sp. specimen. Polinices sp. are believed to be associated with Early Period sites, therefore this specimen was selected to determine if there is Late/Early Period component mixing in the deposit, as this site is considered primarily Late Period. In addition, a Polonicies sp. specimen was sampled from CA-SDI-8797 (considered primarily an Early Period site) for comparison. The sample provided a date (at two-sigma range) of AD 980 to AD 1170 (Cal BP 980 to 780). This date identifies occupation for CA-SDI-8303 within the Late Period. Specimen CA-SDI-8303-66B was also selected from the 60-70-cm level of Unit 11, and is a Donax sp. specimen. Donax sp. is more often associiated with Late Period sites, therefore this specimen was selected to directly compare to specimen CA-SDI-8303-66A. The sample provided a date (at two- sigma range) of AD 1690 to AD 1910 (Cal BP 260 to 40)(see Appendix E). This date also identifies occupation for CA-SDI-8303 within the Late Period. Specimen CA-SDI-8303-256A was selected from the basal (80-90 cm) level of Unit 7, and is a large Argopecten sp. specimen. Large Argopecten sp. are often associated with Early Period sites reflecting a deep flushing lagoon producing a large amount of shellfish, therefore this specimen was selected to identify the presence of Early Period occupation. The sample provided a date (at two- sigma range) of BC 4780 to BC 4550 (Cal BP 6730 to 6500)(see Appendix E). This date identifies an Early Period component for CA-SDI-8303. Specimen CA-SDI-8303-256B was also collected from the basal (80-90 cm) level of Unit 7, and is a Donax sp. specimen. Donax sp. is generally associated with Late Period sites, therefore this specimen was selected to directly compare to specimen CA-SDI-8303-256A. The sample provided a date (at two-sigma range) of AD 1340 to AD 1490 (Cal BP 610 to 460)(see Appendix E). This date PJ.4-04 3-73 August 2005 Table 3-20 CA-SDI-8303: Radiocarbon Dates Site Temp.

Four ofthe specimens' (specimens CA-SDI- 8303-26, - 104, -127, and -231) ttace element concenfrations geochemically place their volcanic glass origins to the Obsidian Butte geochemical type, located in Imperial Coimty, Califomia. Obsidian Butte obsidian is associated with Late Period occupation. Specimen CA-SDI-8303-40 however, provided ttace element concenttations that geochemically placed its volcanic glass origin to the Coso Volcanic Fields geochemical type, located in Kem County, Califomia. This obsidian type is more often associated with Early Period sites in southem Califomia. 3.15 RESIDUE ANALYSIS Residue analysis was conducted by Robert Parr (CSUB) for six projectile point specimens recovered from CA-SDI-8303 (Table 3-21). A single positive reaction was registered for specimen CA-SDI- 8303-82 (Appendix G). The specimen, a small Cottonwood Triangular arrow point with a concave base, reacted positively to guinea-pig antiseram indicating the presence of protein from any species from the squirrel, porcupine, or beaver families. The positive reaction indicates that the arrow point may have been used to hunt these species. Altematively, it may also indicate that the sinew or other portions ofthe species may have been used in the hafting of the arrow point to the arrow shaft. As noted in section 3.11, Califomia ground squirrel was identified in the faunal assemblage. The absence of identifiable proteins on the remaining specimens may be because of poor preservation of proteins, insufficient proteins, or that they were not used on any ofthe organisms included in the available antisera.

The purpose of the Indexing and Preservation Study was to provide an index sample representing the deposit being capped and preserved. In all, the Indexing and Preservation Study at CA-SDI-8303 produced 6 bifaces, 9 arrow points, 1 biface preform, 1 flake blank, 10 battered implements, 18 flakes from battered implements, 3 steep-edged unifacial tools (SEUTs), 2 rejuvenation flakes from SEUTs, 6 flake tools, 1 flake knife, 3 cores, 3,887 debitage, 1 nodule tool, 6 ground stone fragments, 19 manos, 5 metate fragments, 1 polished stone fragment, 1 quartz crystal, 449 ceramic fragments, 12 Olivella sp. shell beads, 7 shell disc beads, 1 Cypraea spadicea Swainson (Chestiiut Cowry) shell, 2 otoliths, 2 glass ttade beads, 1 bone bead, 2 bone tools, 465.4 g of bone, and 32,838.1 g of shell. Disturbance from agricultural activities, bioturbation, and geologic activities was noted in all units. Site CA-SDI-8303 is primarily a Late Period habitation site with good site integrity. Radiocarbon dates and diagnostic artifacts identify the majority of occupation within the Late Period with minimal evidence of Early Period occupation present at the basal excavation level. The range of artifacts at CA-SDI-8303 indicates a habitation/village site occupied at a minimum during the spring and summer seasons (based on availability of plants, animals, and otolith analysis). Flake production from local cobbles suggests flake tool use. Most likely, these tools were manufactured and used at the site. Hunting activities may have occurred near this site as indicated by the presence of nine projectile points in the artifact assemblage. The presence of 30 ground stone tools and 11 battered implements demonsttates preparation of plant foods through pounding and/or grinding. In addition, the large number of fish remains suggests a range of maritime activities including the use of nets and fishing. The presence of shellfish remains and the range of small to large mammal bone demonsttates the range of foods collected, hunted, and processed.

Rogers noted two ceramic sherds, two manos, and a large quantity oi Donax sp. shell on the surface. Moriarty (1974) updated the site and identified a midden with shell on a knoll. Scientific Resource Surveys, Inc. (SRSI)(1982) reported that the site was divided into two loci, with the eastem locus being the larger ofthe two. SRSI also noted differential shell and lithic distribution across the site. A survey by Gallegos & Associates (1997) noted the destmction of a large portion of the site as a resuh of the constraction of College Boulevard (Figure 4-1). The remaining site area represents the southeast portion of the original site. The survey of the property was followed by a test of the remaining site area to determine site significance. Testing for CA-SDI-8694 included the excavationof 18 shovel test pits (STPs) and two Ixl-m units (Gallegos etal. 1999)(see Figure 1-5). This work produced 584 artifacts, 3,477 g of shell, and 33.9 g of bone (see Table 1-3). The presence of a few ceramics identifies a Late Period component. Given the extensive and diverse artifact assemblage present to address research questions, this habitation site, occupied circa 5,160 years ago, was identified as significant under CEQA, Section 15064.5 (3) criteria D. 4.2 CURRENT STUDY The purpose of the data recovery program was to adequately address mitigation of impacts through the completion of collection of surface artifacts, field excavation of a representative sample of the site through excavation of 1x1 -m units, artifact cataloguing, data analysis, and special studies for the purpose of addressing important research questions.

Results by surface collection and excavation units are provided in Sections 4.2.1 and 4.2.2. 4.2.1 Surface Collection The site had been previously surface collected in 1999 (GaUegos et al. 1999). Additional surface artifacts collected as a resuh of the present study include: 1 nodule tool, 2 cores, 1 debitage, 3 battered implements, 4 manos/mano fragments, 2 metates/metate fragments, and 1 ground stone fragment (seeTable4-l). 4.2.2 Unit Excavation For the data recovery program, a total of forty-four 1x1-m units were excavated at CA-SDI-8694 (Figure 4-2). The data recovery program was conducted in two phases. Phase I included a 1% random sample across the sample universe. In all, 28 Ixl-munits were excavated (Units 3 to 19 and 21 to 31). Phase II was based on Phase I results, and was focused on the west-central portion ofthe site. A total of 16 additional units (Units 32 to 47) were excavated in Phase II. Cultiiral material recovered as a result of Phase I and II excavation is listed by unit number in Table 4-1. Unit numbers start from Unit 3, as the test phase for CA-SDI-8694 conducted by Gallegos & Associates (Gallegos et al. 1999) ended with Unit 2. Furthermore, Unit 20 was not excavated because of poor artifact counts for the east portion of the site. Soil sfratigraphy for the units excavated during data recovery conformed to two distinct pattems, Pattems A and B, which are discussed below. Pattem A units were located primarily near the knoll-top on the westem portion of the site, and included Units 3,4, 10 to 15, 23 to 26, 32 to 35, and 37 to 47 (Figure 4-3). These units contain the majority of artifactual materials recovered from the site, and likely represent the primary site area that presently remains on the property. Pattem A exhibits a topsoil of loose, gray-brown sandy loam (Munsell 7.5 YR 4/1) disttirbed historically by agricultural activities. This loam ranged from between 6-20 cm, and contained a moderate amount of cultural materials. The topsoil was generally followed by a moderately compacted, dark gray-brown sandy loam (Munsell 7.5 YR 3/1) with occasional rocks, beginning at depths ranging from 10-20 cm, and terminating between 30-50 cm in depth. This level contained the bulk of cultural materials recovered from CA-SDI-8694. Finally, all units terminated between 40-60 cm witiiin dark gray-brovvoi sandy clay (Munsell 7.5 PJ. 4-04 4-6 August 2005 INSET SHOWING BLOCK EXCAVATION UNITS B = 1x1 Meter Excavation Units Gallegos & Associates CA-SDI-8694 Site Map Showing Data Recovery Units FIGURE 4-2 PATTERN A JH 10 cm 20 cm 30 cm - 40 cm - 50 cm I- CA-SDI-8694 Unit 32 South Wall Profile (50 cm depth) Sf 10 cm 20 cm >- o PATTERN B CA-SDI-8694 Unit 6 West Wall Profile (20 cm depth) Ss:^— KEY I I = loose, dark gray-brown sandy loam with high organic content = light to medium compaction, dark gray-brown sandy loam = highly compacted, gray-brown, gravelly clay with cobbles \+ M = highly compacted, brown clay with fragmented marine shell = larger, subangular clasts Gallegos & Associates CA-SDI-8694; Pattems A and B Unit Profiles FIGURE 4-3 YR 3/1). Although this stratum was primarily devoid of cultural material, it did contain a smear of shell in many ofthe units. This shell is likely a result of geologic and biologic processes that have disturbed the site soil over time. While the developed, cultural material-bearing soil that was observed in the secondary layer remained consistent throughout the site (moderately compacted, dark gray-brown sandy loam (Munsell 7.5 YR 3/1), the underiying subsoils varied in accordance with site topography. Sttatigraphic profiles are provided in Appendix D. Table 4-1 provides unit artifact and ecofact recovery counts and weights. Pattem B units were primarily located on lower slopes, roughly in the eastem portion of the data recovery area, and included Units 5 to 9, 16 to 19, 27 to 31, and 36 (see Figure 4-3). In addition. Units 21 and 22 exhibited a similar pattem to the eastem units although they were located in the westem portion ofthe site. Pattem B is represented by a thin topsoil of loose, brown sandy loam (Munsell 7.5 YR 4/2) disturbed historically by agricultural activities. This loam ranged from between 0-10 cm and contained little cultiiral materials. The topsoil was underlain by a moderately compacted, dark gray-brown sandy loam (Munsell 7.5 YR 3/1) with rocks, beginning at depths ranging from 10-20 cm, and terminating between 30-40 cm in depth. Finally, all units terminated between 30-50 cm within dark gray-brown sandy clay mixed with several cobbles (Munsell 7.5 YR 3/1). Although the strata in the two unit models do not differ drastically in color or texture, the amount of cultural materials, shallowtiess of the units, and presence of a cobble layer at depth set them apart from the core area ofthe site. While the small amount of developed, cultural material- bearing soil that was observed in the secondary layer remained consistent throughout the site (moderately compacted, dark gray-brown sandy loam, Munsell 7.5 YR 3/1), the underlying subsoils varied in accordance with site topography. Sfratigraphic profiles and unit tables are provided in Appendix D. See Table 4-1 for unit artifact and ecofact recovery counts and weights. 4.3 ARTIFACT ANALYSIS The artifact assemblage from CA-SDI-8694 consists of a wide range of artifact types including 4 bifaces, 5 cores, 1 piece of tested raw material, 8 nodule tools, 4 utilized flake tools, 4 steep-edged unifacial tools (SEUTs), 10 flakes from SEUTs, 2,367 debitage, 1 hammerstone, 22 battered PJ. 4-04 4-9 August 2005 t i 1 I I 1 I I 1 I I I i I implements, 19 flakes from battered implements, 61 manos/mano fragments, 6 metates/metate fragments, 18 ground stone fragments, 1 shaped stone, 260 ceramic fragments, 1 Olivella sp. shell bead, 2 bone awls, 1 bone fishing toggle, 1 bone bead, and 1 possible otolith pendant (see Table 4- 1). Faunal material includes 76,492.08 g of shell, 4 otoliths, and 167.9 g of bone. The following sections describe the results of analyses performed for all materials recovered from the present study. 4.4 DEBITAGE ANALYSIS (By Jeff Flenniken and Tracy Sfropes) 4.4.1 Methodology Technological lithic analysis based upon replicative data was conducted for all flaked stone artifacts identified from this debitage sample recovered from CA-SDI-8694. Technological identifications were determined for all analyzed flaked stone artifacts. Lithic artifacts were categorized according to toolstone material type (metavolcanic, quartz [quartzite, vein quartz, quartz crystal], chert, and obsidian), technological category (tecat), and reduction stage (Appendix B). Reduction stage flake categories were defined by comparing technological attiibutes of replicated (experimental) artifacts from known and cataloged flaked stone tool reduction technologies to the prehistoric confrols. In tum, by comparing tiie technological attributes of prehistoric artifacts (conttols) to the technological atfributes of known artifacts in terms of manufacture, reduction stages were assigned to technologically diagnostic debitage. Some debitage, however, was considered technologically nondiagnostic because of the lack of technological attiibutes (i.e., platforms) on fragmentary pieces. Atfributes evidenced on the prehistoric debitage, in conjunction with experimental analogs, were used to identify technologically diagnostic debitage that enabled flakes to be assigned to specific experimentally derived reduction stages (Flenniken 1978, 1981). The remaining debitage was not ascribed to any reduction stage because of the fragmentary nature of the artifacts. Therefore, fragmentary debitage was characterized as technologically nondiagnostic, altiiough atiributes such as material type, and presence/absence and type of cortex were noted. PJ. 4-04 4-10 August 2005 I 1 I i I 4.4.2 Analyzed Sample The debitage included in this analysis was recovered from 43 (Units 3 to 19, and 21 to 47) ofthe 44 Ixl-m units excavated at CA-SDI-8694. In all, 152 IxlxO.l-m levels were excavated, producing a flaked stone debitage assemblage sample of2,366 artifacts (Tables 4-2 and 4-3). Each flaked stone artifact from the data recovery program was analyzed and recorded as a separate entity in an attempt to identify and isolate technological variation and site flintknapping activity(s). Evidence to support intentionally different technological tteatment of different lithic materials within the analyzed sample was minimal. The different lithic materials (metavolcanic, quartz, chert, and obsidian) identified from this infra-site sample were reduced following two reduction techniques, primarily nodule core reduction, and to a much lesser extent, but a continuation of fhe nodule core reduction, biface reduction. Therefore, because of the near lack of intta-site vertical and horizontal technological variation and differential lithic reduction tteatment, and the near complete use of metavolcanic materials as toolstone (n=2,192 or 91.3 %>), all flaked stone artifacts and materials were combined for site interpretation. Eleven flakes (0.9%o of the diagnostic debitage) were identified as biface reduction debitage, and included all four identified toolstones from this site (see Table 4-2). Therefore, 99.1%) of the analyzed sample of technologically diagnostic debitage represented nodule core reduction (n= 1,186), while less than one percent represented biface reduction (n=l 1). Furthermore, because of the very small sample, these 11 flakes identified as biface reduction may have been fortuitously categorized based upon technological attributes that overlap with other tecats, or biface reduction was minimally practiced at this site. The analyzed debitage recovered from these 44 subsurface contexts was similar in technological character, and did not support technological variation at different locations across the site. Based upon this analysis, prehistoric technological homogeneity was maintained both vertically and horizontally across the site, as different flintknapping activity areas were not identified. By combining materials, the technologically diagnostic debitage (n=l,197, 50.6% ofthe total 2,366 artifacts) provided an adequate sample for interpretation of site flintknapping activities. Therefore, all technologically diagnostic flaked stone artifacts from tiiis analyzed sample were combined PJ. 4-04 4-11 August 2005 Table 4-2 CA-SDI-8694: Technologically Diagnostic Debitage Toolstone Materials TECAT .

Again, only the technologically diagnostic debitage was employed for interpretation of CA-SDI-8694 flintknapping activities. 4.4.3 Technological Artifact Categories (tecats) Technological analysis ofthe debitage from CA-SDI-8694 identified a very interesting, and limited technologically, flaked stone tool assemblage. The technological end of one reduction continuum (nodule core), or the last stage of reduction, was well represented at this site. Debitage classification atfributes were divided into tecats that reflect technological differences in the reduction continuum and reduction stages that occurred at this site (Appendix,B). Continuum is defined as a process that includes the entire life cycle of a specific flaked stone tool (including all debitage) from the selection of the raw lithic material, initial decortication, heat freatment (if applicable), reduction into the original tool, use and reuse of that tool (which may be multi-functional), rejuvenation of that tool, the deposition of that tool into archaeological context, and possible reuse of that tool later in prehistoric time. Reduction stage, as employed for this analysis, is a concept designed to separate a flintknapping continuum for analytical purposes only. The reduction-oriented technological stages (processes) employed in this analysis, the flake categories, based upon replicated artifacts that correspond to those processes, and the flake attributes used to define those categories are, with few exceptions (n=ll bifacial tecats), within the nodule core reduction technology that was well established in prehistoric southem Califomia. Nodule core reduction is known in the southem Califomia archaeological literature as "Cobble Core Reduction" (Gallegos et al. 2002; Gallegos et al. 2003). The term nodule was substituted for cobble because the term cobble is geologically defined as a size clast (64-256 mm) and many prehistoric core and core-based artifacts (such as some battered implements) were manufactured from boulders(>256 mm), and, to a much less extent, pebbles (4-64 mm). The term nodule was selected because a nodule can be any size and tend to be somewhat rounded to subrounded. Nodule core debitage was recognized and grouped into technological categories based on the amount and location of dorsal cortex, platform attributes, dorsal arris count and direction, and flake PJ. 4-04 4-14 August 2005 I 1 n K I tt tt I 1 i I » » I I 1 I 1 1 cross/long-section shape. Debitage was classified according to three platform types identified among the flakes from nodule core reduction: natural/cortical platforms (NP), single-faceted platforms (SEP), and multi-faceted platforms (MFP). Flakes were fiirther subdivided according to the location of dorsal cortex (tecats include NP-1 through NP-11, SFP-1 through SFP-11, and MFP- 1 through MFP-11 )(Appendix B). The reduction-oriented technological categories of diagnostic flakes were also segregated on the basis of geological material (metavolcanic, quartz [quartzite, vein quartz, quartz crystal], chert, and obsidian). Flake fragments that lacked the necessary attributes to be placed in one of these reduction-oriented tecats were classified as technologically nondiagnostic debitage with and witiiout cortex. Only raw material type and presence or absence of cortex were recorded for these artifacts. Interpretation ofthe reduction sequence from this site was determined using only the technologically diagnostic debitage, whereas discussions conceming lithic raw material types include all debitage and formed artifacts. Metavolcanic nodules (cobbles and boulders) were selected for size, shape, material quality, and platform location. Nodules with natiiral platforms were reduced directiy by percussion in a more or less circular manner around the natural platform. The location of dorsal cortex indicates the sequence of flake removals (Appendix B). Cores with faceted platforms were nodules that required platform preparation prior to reduction. This occurred usually when a nodule of quality material was selected, but the nodule did not possess a naturally appropriate platform. It was therefore necessary to create a platform by percussion flaking. The desired products of nodule core reduction were flake blanks that were thick in cross-section, long and narrow in plan view, and ranged in length depending upon intended use, but were most likely 5 to 12 cm in length. 4.4.4 Toolstone Materials The lithic materials employed by the prehistoric knappers at this site included a variety of metavolcanic rock, quartz (quartzite, vein quartz, monocrystalline quartz), chert, and obsidian, mostly all collected from alluvial deposits. Obsidian is the only non-local toolstone material identified in the assemblage sample. All (100%o) of the identified cortex was incipient cone cortex PJ.4-04 ' 4-15 August 2005 I I tt tt I 1 1 » I I I I 1 resulting from water transportation ofthe lithic nodule used for toolstone. This suggests that tiie nodules used for toolstone were prehistorically collected from alluvial (past or present) environments. Metavolcanic materials are found as pebbles, cobbles, and boulders derived from Eocene volcanic rhyolites, andesites, and diabase of basaltic composition (Clevenger 1982). These materials have been extensively metamorphosed causing stiiictiiral recrystallization and a rather porphyritic nature H (Clevenger 1982). Metavolcanic rocks range in color from green to brown to black and require great dynamic loading forces to fractiire conchoidally. Distinctive Santiago Peak Metavolcanic (known I locally as "felsite"), found as bedrock in San Diego County and redeposited as float, was highly represented in this analyzed assemblage. I Quartz is one ofthe most common lithic materials, and occurs m a wide vanety of hexagonal pnsms H that are terminated by pyramidal shapes. It also occurs in massive, granular, concretionary, stalactitic, and cryptocrystalline habits (i.e., vein quartz). When combined with other materials, I quartz or metaquartzite is referred to as quartzite, whereas a single crystal is called monocrystalline quartz. Colors range from white, red, grey, purple, yellow, brown, pink, black, green, and can be I coloriess as well. Quartz is ttansparent to franslucent with some forms occurring as opaque (i.e., quartzite). Quartz has a hardness of 7, a specific gravity of 2.65, and fracttires conchoidally (Chesterman 1995; Klein andHurlburt 1985; Luedtke 1992; Pellant 1995). Chert is an opaque form of microcrystaUine quartz composed of numerous grains that form a granular crystalline stracture. Chert and jasper are chemically precipitated sedimentary rocks that are classed as microcrystalline but may contain sheaf-like aggregates that may include impurities such as clays, silts, carbonates, pyrites, iron, or other organic materials. Chert and jasper also may contain several forms of silica such as opal, chalcedony, or cryptocrystalline quartz. Cherts range in color from white to light gray to black. Jasper, because ofthe iron, is red, yellow, or brown. Green jasper is called prase or chyrsoprase. Jasper is distinguished from chert on the basis of color (Chesterman 1995; Klein andHurlburt 1985; Luedtke 1985; PeUant 1995). PJ. 4-04 4-16 August 2005 s 1 I tt g I I I I I i 1 I I I Obsidian is an igneous glass that is non-crystalline and often has a bright vifreous luster. Obsidian has a specific gravity (G) of 2.4 and is slightly harder than common window glass (H=5.5). It forms as a result ofthe rapid cooling of extrasive magma, preventing any crystalline growth, or as a result of a viscous magma that was too rigid to support crystalline growth. Obsidian is usually black, but gray, red, brown, green, and even blue are common in specific geological locations in westem North America. The red colors are because of the inclusion of magnetite or hematite. Obsidian is usually 'I ttanslucent, but can occur as ttansparent or opaque (Chesterman 1995; Klein and Huriburt 1985; Luedtke 1992; PeUant 1995). I 4.4.5 Analytical Results: Technologically Diagnostic Debitage • Introduction ]| This analyzed debitage assemblage consisted of2,366 flakes and flake fragments manufactured from four different raw lithic material groups (see Tables 4-2 and 4-3). A total of 1,197 (50.6%) artifacts I were technologically diagnostic, while 1,169 (49.4%) flake fragments were technologically nondiagnostic (see Tables 4-2 and 4-3). Of the 1,169 technologically diagnostic artifacts in this CA- II SDI-8694 sample, 1,186 artifacts represented nodule core reduction technology, while 11 artifacts represented biface reduction (see Table 4-2). • Nodule Core Reduction Three nodule core platform types (NP, SEP, and MFP) were represented in this debitage sample (see Table 4-2 and Appendix B)(Gallegos et al. 2002; Gallegos et al. 2003). Natiiral platform (NP) debitage was represented by 795 flakes, single-faceted platform (SFP) debitage was represented by 346 flakes, and multi-faceted platform (MFP) debitage included 45 flakes (see Table 4-2). The most frequent (n=770) natural platform debitage category was NP-11, or flakes devoid of dorsal surface cortex (see Table 4-2). This tecat is produced well after cortex removal and flake blank production is in full force. Given the small overall size of the NP-11 flakes identified during this analysis, these flakes were most likely produced at the very end of flake core reduction just prior to the cores becoming exhausted and discarded, and/or laterally cycled into another fimctional tools such as battered implements and/or adzes. The remaining 25 other natural platform flakes were produced throughout the reduction cycle, and exhibited dorsal cortex (see Table 4-2). PJ. 4-04 4-17 August 2005 s I I tt 1 I I I 1 I I I I I The same technological'reduction pattem was repeated, almost identically, in the single-faceted platform debitage and the multi-faceted platfonn debitage (see Table 4-2 to compare NP tecats to SFP and MFP tecats)(see Appendix B). The most commonly occurnng (n=242) single-faceted platforai debitage category was SFP-11, and the most common (n=34) multi-faceted platform debitage tecat was MFP-11 (see Table 4-2). Most of the recovered debitage was too small for flake blanks, or was broken, or too thick, and was therefore discarded. Sheared cones, resulting from excessive dynamic loading (stiikirig the core too hard by direct free hand percussion), were responsible for most flake blank breakage. For the most part, the CA-SDI-8694 nodule core debitage sample is small in overall size (< 3 cm long). This debitage produced from flake cores was placed into two general technique categories: rejected flake blanks or working face preparation flakes. Rejected flake blanks may be the appropriate length (> 5 cm), but were rejected because they were too thick, too nan-ow, covered witii too much cortex, too many stacked step fractiires on the dorsal surface, broken by sheared cones (very common at this site), etc. Working face preparation flakes are generally too small (< 3 cm), ttiangular in cross-section, and thick for use as they were most frequentiy produced as platfonn over-hang removal flakes, and/or to sfraighten the anises on the face of the core. Useable flake blanks may have been transported from the site for use elsewhere. • Biface Reduction Diagnostic debitage was separated into tecats that may support minimal biface reduction (see Appendix B). Separation was based upon technological attributes conceming material quality (very fine-grained green [possibly Santiago Peak] metavolcanic material, fine-grained quartzite, quartz crystal, chert, and obsidian), flake thickness, number and position of dorsal arrises, platform type and size, and flake cross/long-sections. Therefore, the high flintknapping quality flakes possessed attiibutes of a biface reduction sequence. Knowing that only an entire flaked stone assemblage can accurately reflect tiie complete technological character of an archaeological site, these "biface" flakes identify biface reduction at this site (see Appendix B). Biface manufactture was not well represented in this sample, as only 11 (0.9%) ofthe technologically diagnostic debitage represented biface reduction (see Table 4-2). PJ. 4-04 4-18 August 2005 I 1 I I I I I I I I I I I I I 1 I I I Stage 1, core reduction, debitage was not identified at this site, and was most likely not misidentified as nodule core reduction debitage because the nodule core reduction debitage was produced from a much poorer flintimapping quality of toolstones. Stage 2, edge preparation, debitage was represented by two edge preparation flakes that exhibited detachment scars (204.E+) indicating flake blank manufacture similar to nodule core reduction. Seven Stage 3, percussion biface thinning, flakes (302.E-) were identified in this site sample. These flakes represented biface thinning at this site (see Table 4-2). The seven early percussion bifacial thinning flakes (302.E-), created when bifaces are thinned, support bifacial flintimapping activities. These flakes were small, but well formed, indicating bifaces were already well-shaped prior to the removal of these few flakes. Possibly larger, well-made bifaces from higher quality toolstone materials were ttansported to this site, and occasionally thinned, but not manufactured at this location. Pressure flaking was represented at this site (see Table 4-2) by two (0.2% of the technologically diagnostic debitage) Stage 4, early stage pressure bifacial thinning flakes (400.E-). These flakes exhibited classic pressure flake attributes, but a sample of two flakes suggests these flakes were fortuitous. These pressure flakes may have also been produced from non-bifacial tool (such as unifacial tools) resharpening or shaping. 4.4.6 Analytical Results: Technologically Nondiagnostic Debitage • With Cortex One hundred eighty-two (165 metavolcanic, 15 quartz, and 2 chert) technologically nondiagnostic flake fragments that exhibited incipient cone cortex were examined for this analysis (see Table 4-3). Most of these flake fragments, many broken during production by sheared cones, were small, angular, and appeared to be by-products of nodule core reduction. • Without Cortex Nine hundred eighty-seven (855 metavolcanic, 111 quartz, 20 chert, and 1 obsidian) technologically nondiagnostic, cortex-free flake fragments were also examined for this analysis (see Table 4-3). As PJ. 4-04 4-19 August 2005 I I I I I I I I 1 I I I I I I 1 I I I with the cortical flake fragments, most of these pieces of debitage were small, angular, and appeared to be by-products of nodule core reduction. Sheared cones, produced during flake production, created most of these broken flakes. 4.4.7 Technological and Functional Summary • Nodule Core Reduction Nodule core reduction technology is the most common core technology identified in this CA-SDI- 8694 sample (Gallegos et al. 2002; GaUegos et al. 2003). Products of nodule core reduction are also tiie most abundant as measured by percent (99.1 %) of technologically diagnostic flakes. This simple and expedient technology may have been so commonly used because it provided a simple and relatively effortless way to produce usefiil flakes, and flake blanks intended for immediate use or further reduction. Because ofthe local (San Diego County) abundance of metavolcanic materials, there was often little need for more material-efficient, and consequently more time-consuming technologies. Debitage produced from nodule core reduction was classified according to the pattem of dorsal cortex present (if any), dorsal anis patterns, and platfonn attributes. Dorsal cortex attributes provide clues conceming two processes: stage of reduction and patteming of flake removals. The amount of cortex will decrease through the reduction sequence. Flakes with 100% dorsal cortex (NP/SFP/MFP-ls), therefore, usually result from eariier portions of the sequence while flakes with no dorsal cortex (NP/SFP/MFP-1 Is) result from the latter portions ofthe sequence. The abundance offtakes that lack dorsal cortex exist because, once cortex is removed from a nodule early in tiie reduction sequence, all subsequent flakes will lack dorsal cortex. The positioning of dorsal cortex results from the patteming of flake removals (clockwise, counterclockwise, or unpattemed in relation to the platform). The analysis of this debitage sample did, to a limited degree, reveal a potentially meaningful pattem regarding flake removal for some flakes. While nodule core reduction was the dominant flake stone reduction technology practiced at this site, the Topaz Mountain reduction technique (a variation of the nodule core reduction .technique) may have also been employed (21 flakes, 3 NP-4 and 18 NP-11) to maximize the amount PJ. 4-04 4-20 August 2005 I I I I I I I I I I I I I I I 1 I I I of flake blanks that could be produced from an oddly-shaped elongated pebble/cobble-size nodule of quality material. The Topaz Mountain technique is discussed later in this section. Another aspect of variability seen in the nodule core reduction debitage assemblages relates to platform characteristics. This variability also appears to resuh purely from technological considerations, rather than, for instance, a "mental template" to which might be attached some chronological or ethnic significance. Three examples of platforms are frequently found (unprepared/nattu-al/cortical [NP], single-faceted [SFP], and multi-faceted [MFP]), and tiiey vary, in part, according to the amount of shaping required to obtain a suitable platform configuration for successfiil flake removals (a unifonn platform surface and adequate platform-to-core face angle). Some nodules did not require shaping (natiiral platforms) to obtain a proper platform configuration; others required more (mutti-faceted platforms) or less (single-faceted platforms) shaping. It is expected that these different platform types could be produced witiiin a single reduction sequence as a result of adjustinents made in response to the changing shape ofthe core as it was reduced. One source of inter-site variation may relate to the portion ofthe nodule core reduction sequence conducted at a site. It appears that cores were not always entirely reduced at a single location, but rather initial shaping may have been performed at one site, and subsequent core reduction was performed at another. This is indicated at some sites where few early stage flakes were found, but later stage flakes were common. At CA-SDI-8694,88.2%) of the nodule core debitage was assigned to the "end stage" of core reduction, while only 11.8% ofthe nodule core debitage represented all other earlier flake production tecats. • Topaz Mountain Reduction The Topaz Mountain technique (a specialized nodule core reduction technique) is applied to a rounded-to-subrounded, elongated pebble, cobble, or boulder. A distal end ofthe elongated pebble, cobble, or boulder is removed by direct free hand percussion. The remaining flakes are produced by direct free hand percussion "sectioning" of the core, thus all flakes have cortical rim platforms. PJ. 4-04 4-21 August 2005 1 1 I I I I I I I I I 1 I I I 1 I I I Four flake types frequently occur. Linear cortical flakes reflect the flintknapper's attempt to flatten the working surface of a Topaz Mountain core. This step is necessary if large flat flakes are to be subsequently removed from the core. A cortical platform is required for the manufacture of linear cortical flakes. The platform occurs above and in line with an axis that divides the dorsal surface of the prospective flake into a portion containing cortex, and a portion containing a segment oftiie facet left by removal of the first split flake (Raymond 1984). Broad cortical (around the edges) flakes were produced after linear cortical flakes were removed from the core. To produce broad cortical flakes the knapper must hold the split core in one hand, with the split facet side facing away from the knapper. The other hand uses a hammerstone to stiike the cortex ofthe core just above the perimeter ofthe split core face via direct free hand percussion. The point chosen for a platform depends on the angle formed by the core's working face and adjacent cortical surface. Generally, the most suitable location for a platform is in line with a ridge or undulation on the core's working surface, and at a ridge or area of high mass on the exterior cortical surface of the core (Raymond 1984). Under ideal circumstances the applied force fravels all the way through the Topaz Mountain core. This results in the largest and widest possible flake, and can be viewed as a successfiil "section" or "slice" of the core. Less ideally, the flake terminates with a hinge fracture in the middle of the working face ofthe core. Such "unsuccessful" flakes were discarded (Raymond 1984). As production of broad cortical flakes continued, the flintknapper rotated the Topaz Mountain core on an axis perpendicular to its working surface, aligning cortical platforms with working surface morphology for further flake removals. In the process the core becomes smaller, yet the original cortex surface remains at the edge of the dorsal face of each flake (Raymond 1984). All flakes produced (except the first flake, which can be identified as a NP-1 flake) are technically versions of NP-5, NP-6, NP-7, NP- 10, and NP-11 flakes. However, these flakes are not removed to decorticate the nodule. Produced flakes serve as flake blanks for tool manufacture. The cortex remaining on the edges ofthe Topaz Mountain flakes has three functions: 1) to serve as consistent PJ. 4-04 4-22 August 2005 I I I I I I 1 I I I 1 I 1 I I 1 I I I platforms; 2) to serve as natural backing for flake tools; and/or, 3) to help maintain flat flakes during flake removal. The CA-SDI-8694 sample provides 21 flakes and potentially numerous flake fragments that may have been produced using the Topaz Mountain technique. However, because ofthe high degree of sheared cones, these flakes could not be identified as being unequivocally produced by the Topaz Mountain technique. While virttially all NP-11 (as well as NP-4, NP-5, NP-6, and NP-7) flakes were broken as a result of sheared cones, it is expected that some of these flakes may have been Topaz Mountain flakes. • Adze Flakes Ten adze resharpening flakes were identified during the analysis of this debitage sample. This tecat (1005.AZ Flake) typically has a pronounced single-faceted platform (very few have cortical or multi-faceted platforms), multiple series of clusters of stacked step fracttires on the proximal end of the dorsal surface, multiple linear flake scars and anises (unidirectional from the platform or planer surface) on the dorsal surface, more or less parallel side margins, slightly curved in long-section, feather or stepped distal end terminations, and most importantly, have excessive polish (from contact with wood surfaces) with linear striations that are pattemed perpendicular (or oblique) to the flake platform as well as the margin of the adze from which it was produced. Tecat 1005.AZ Flake specifies adze resharpening (see Table 4-2). 4.4.8 Conclusions The analyzed debitage assemblage from CA-SDI-8694 provided ari example of a site wherein the last stages of nodule core reduction (and possibly Topaz Mountain core reduction) occuned. Of the nodule core reduction flakes identified in this sample, 1,046 (87.5%)) were NP-11, SFP-11, and MFP-11 (see Table 4-2). Therefore, the primary flintknapping activity that occurred at this site was associated with nodule core reduction, and the predominant aspect of nodule core reduction was the production of a few late stage flake blanks, most likely for unmodified flake tools and potentially bifaces. Selection of metavolcanic nodule core toolstone, nodule core platform preparation, nodule PJ.4-04 4-23 August 2005 1 1 1 I 1 1 1 1 I 1 1 I I 1 1 I 1 I 1 core decortication and manufacture, and extensive nodule core reduction did not occur at this site. Only late stage flake blanks were produced at this location. The 10 adze flakes from CA-SDI-8694 support on-site woodworking activities. Adzes (SEUTs), effective woodworking tools (Gallegos et al. 2002; Gallegos et al. 2003), are typically "...circular or semi-circular in outline form and have a low profile for the frontal view with the contiguous planer use-wear located near the working element" (Schroth and Flenniken 1997). Based upon the resharpening debitage (1005.AZ-Flake), functioning adzes (manufactured directiy from a metavolcanic nodule that produced nodule core reduction debitage, and/or were laterally cycled exhausted cores) were employed at this site as woodworking tools. The three flake tools also support minimal woodworking activities. Based upon the analyzed debitage sample from CA-SDI-8694, flintknapping activities were limited to nodule core flake blank production, minimal thinning by percussion and pressure flaking of well- made bifaces, resharpening of adzes that may have been laterally cycled from exhausted flake cores, and, resharpening of manos and metates with battered implements that may have also been laterally cycled from exhausted flake cores. 4.5 FORMED ARTIFACT ANALYSIS (by Tracy Sfropes and Jeff Flenniken) 4.5.1 Points and Bifaces The four bifacial specimens recovered from CA-SDI-8694 suggest that a small amount of bifacial retooling and/or rejuvenation of projectile points and/or bifaces was performed at the site (Figure 4- 4). Two of the four specimens are composed of quartz (specimens CA-SDI-8694-189, and -303), while the remaining specimens are composed of metavolcanic material (specimens CA-SDL8694- 497, and -630). In addition to the projectile points, bifacial debitage was also recovered. Specimen CA-SDI-8694-189 was recovered from the 0-10-cm level of Unit 11. Specimen CA-SDI-8694-303 was recovered from the 40-50-cm level of Unit 25. Specimen CA-SDI-8694-597 was recovered from the 0-10-cm level of Unit 44. Specimen CA-SDI-8694-630 was recovered from the 20-30 cm level of Unit 47. The weight of each of the complete projectile point specimens places them well PJ. 4-04 4-24 August 2005 i CA-SDI-8694-303 CA-SDI-8694-189 Gallegos & Associates Scale 1:1 Example of Bifaces from CA-SDI-8694 FIGURE 4-4 i I 1 I I I I I I I i i 1 I i 1 I I within the weight range (<3.5 g) for anow points (Fenenga 1953). This suggests a date of roughly less than 1,500 years ago (Yohe 1992) for the site, given the introduction and use ofthe bow and anow circa 1,500 years ago. Evidence of rejuvenation in the form of chevron flaking (Woods 1988) is present on the distal end (the tip) of specimen CA-SDI-8694-303 indicating that the point may have been damaged during use (i.e., in a hunting situation), and required retooling for fiirther use. However, as the site appears to be a mixed deposit with both Early and Late Period components, it is possible that this point is not an anow point at all, but rather a dart point that was rejuvenated and later discarded. Typologically, specimen CA-SDI-8694-303 would fall into the Pinto category. In confrast, specimen CA-SDI-8694-189 is a much smaller projectile (anow point) that is readily identifiable to the Cottonwood Triangular family. The remaining biface fragments were too fragmentary to provide information conceming intended use. 4.5.2 Cores and Tested Raw Material Cores represent the parental mass from which flakes were removed for use as tools. The orientation and pattems ofthe remnant flake scars left by the removal of the flakes define the core type. Five cores were recovered from CA-SDI-8694. The five cores were represented by four unidirectional single-faceted platform nodule cores and one multidirectional multi-faceted platform nodule core. All ofthe cores lacked cortex and were quite small (smaller than fist size). This suggests that the cores had become too small for further reduction and/or recycling into another tool form (i.e., SEUT or battered implement). The presence of these cores further supports nodule core reduction activities at CA-SDI-8694. In addition, a single piece of tested raw material (TRM) was also recovered at CA-SDI-8694. TRM is a piece of lithic material that at one time or another was tested for isottopity (the ability to flake) by a native inhabitant. This type of artifact is usually represented by a few attempted flake removals on a piece of raw material that proved to be undesirable for flake reduction or tool formation. The piece of raw material is subsequently discarded. Specimen CA-SDI-8694- 359 proved to be a specimen of relatively low-grade material preventing ease of reduction. 4.5.3 Utilized Flake Tools Utilized flakes are flakes with a minimal amount or no shaping, witii modification (if any) generally restricted to the working edge often resulting from naturally occuning use-wear. These tools are PJ. 4-04 4-26 August 2005 frequently used for a short period of time, then discarded. A total of seven flake tools/flake tool fragments were identified in the present collection. All of the flake tools are laterally utilized flakes. Laterally utilized flake tools exhibit use or modification along a single lateral margin ofthe flake from the tools were produced. In addition, small areas of polish are exhibited on natural anises on the flake tools suggesting use in a scraping activity. All specimens maintain relatively sfraight edges. The angles of the working faces of the specimens are relatively low (less than 45 degrees). It is likely that these flake tools were used in a scraping motion for various purposes, including the working of opposing curved surfaces (such as vegetable products), animal materials (such as animal hides), and even other softer stone. In addition, all of the flake tools were produced from nodule core reduction. 4.5.4 Steep-Edged Unifacial Tools (SEUTs) Southem Califomia archaeology has recovered numerous amorphous lumps of metavolcanic stone that possess steep, unifacial edges for years. These objects have long been recognized by archaeologists as artifacts. However, these steep-edged unifacial tools, or SEUTs, have been subjected too numerous morphological and functional categories (i.e., horse hoof scraper, scraper plane, flake scraper, biscuit scraper, various core types, etc.). Schroth's (1997) analysis of flaked stone tools from CA-SDI-11424, is by far the best effort to sort these artifacts into techno-functional categories. The category of adze, or woodworking tool, defines these tools. Four SEUTs and ten flakes from SEUTs (adzes) were recovered from CA-SDI-8694. SEUTs are plano-convex in cross-section, have steep sides, are almost circular in plan view, are heavy, and most importantly, have sfrong acute cutting edges. These tools are ideal woodworking tools because they are often sharp, weighted, and durable. Brian Hayden's (1979) ethnographic study in Austtalia, Paleolithic Reflections, describes the manufacture and use of SEUTs by Austtalia's indigenous people in great detail. Given that the environments of Austtalia and southem Califomia are very similar, and that tools for woodworking were essential aspects ofthe prehistoric tool kit, southem Califomia SEUTs were most likely used in a similar manner. This functional interpretation is supported by the fact that these two tool PJ. 4-04 4-27 August 2005 categories are the same in terms of manufacture, material quality, size, shape, wear pattems, and overall variation. Additionally, experimentation described by Schroth (1997) supports the use of SEUTs as adzes. Morphological variation within the SEUT category is, perhaps, the main reason for the numerous scraper, plane, etc., categories. However, this variation in size and weight was a technological consideration for the various tasks required of these tools. With basically the same atiributes, except size and weight, these tools functioned as adzes, with different sizes and weights being essential for the different tasks at hand. The most critical atiribute, in addition to size and weight, was the acute, sharp cutting edge. When this edge became dulled during woodworking, the tool was resharpened or rejuvenated by removing flakes from tiie steep face while employing the piano-surface as a platform. These flakes are diagnostic, and were identified at CA-SDI-8694. The four SEUTs and ten flakes from SEUTs identified in the present collection are very similar to other known SEUT/adze specimens recovered from sites such as CA-SDI-12814 (Gallegos et al. 2001), and CA-SDI-5581 (Gallegos and Sfropes 1999). However, the specimens from GA-SDI- 8694 are considerably smaller than the average SEUT/adze specimen. The present size of the specimens may be a reflection of use-life termination, and not the ideal tool size and form. The specimens exhibit primarily unifacial use-wear, with a minimal amount of grinding visible on the ventral surface. The small size of these tools may indicate more confroUed tool functions such as specified scraping tasks ranging from fiber processing to the shaping of bone or wood artifacts. 4.5.5 Hammerstone A single hammerstone was recovered from excavations at CA-SDI-8694. The hammerstone displays several faceted areas, mdicating use as a core reduction hammerstone, or knapping hammer. Evidence of direct blows into the face of a hammer is common in other activities such as hulling nuts, crashing bone, or maintaining milling tools. PJ.4-04 4-28 August 2005 4.5.6 Battered Implements Twenty-two battered implements and nineteen battered implement flakes were examined during this analysis. These artifacts support a ground stone technology in association with the flaked stone technology at CA-SDI-8694. Prehistoric flaked stone assemblages from southem Califomia, Utah, Nevada, and the American Southwest contain a common artifact identified by archaeologists by a variety of names including chopper, hammerstone, pounder, muller, milling stone, flaked hammerstone, handstone, battered hammerstone, masher, basher, utilized core, scraper planes, pecking stone, fist ax, and hand ax (Dodd 1979; Wallace 1978). Many of these artifacts are employed as archaeological identifiers of specific prehistoric cultures (Wallace 1954; Kowta 1969). Others are simply weighed, measured, and described generally as plant and animal resource processing tools. Dodd (1979) and others (Ambler 1985; Geib 1986), however, have devoted considerable time and energy to the identification and function of a rather unsophisticated but highly specialized and important prehistoric tool class, battered hammerstones. Battered hammerstones are separated from other artifact classes on the basis of pock marks located on one or more intentionally prepared areas on a single tool that are a resuh of repeated pounding against another hard object. These implements are most frequently produced from conchoidal fractiiring, subrounded to subangular, spherical to discoidal, cobble-sized, quartzite, chert, metavolcanic, and volcanic nodular alluvial materials. The manufacturing process includes the selection of a check-free rock (or, most likely at CA-SDI- 8694, an exhausted nodule core) ofthe appropriate material and size. After material selection, a unifacial or bifacial sinuous edge (or platform edge on a flake core) was produced by direct free hand percussion. The sinuous edge may have been situated on the side of the nodule, end ofthe nodule, or completely sunounding the nodule. The debitage produced as a result of edge manufacture is characteristic of initial nodule reduction, but is not well-pattemed because ofthe variation in size, shape, and quality of the selected cobble. Because a sinuous edge was the "intended end product," general debitage characteristics may include cortex (in varying amounts) on PJ.4-04 4-29 August 2005 the dorsal surfaces and platforms, few dorsal surface arrises, hinge terminations, thick flake cross- sections, angular flake plan views, single-faceted platforms, and more rarely, multi-faceted platforms. Once the sinuous edges were produced to satisfaction, the linear-edged hammerstone was ready for use. The use of these hammerstones produced battered edges: the longer the use, the'more intense the battering. At some time during the use process, the battered hammerstone required resharpening. Resharpening included the removal of flakes by direct free hand percussion along the sinuous margin until the battered edge surfaces were partially or totally eliminated. A portion of the debitage produced during the resharpening process is very distinctive in that the battered edge that was once on the hammerstone is present on the proximal end of the dorsal surface of the resharpening flake (battered implement flakes, 1005.AZ Flake). Additionally, some battered implement flakes (1005.AZ Flake) are produced during use (from block [battered implement] on block [metate]). However, flakes that do not exhibit battering on their dorsal surface were also produced, and are impossible to assign to the resharpening process. Once again, the hammerstone was ready for use. After numerous use/resharpening events, battered tools were discarded into the archaeological context. These discarded battered implements occur as exhausted, well-wom, intensely battered tools, or as resharpened, sharp-edged, small hammerstones with isolated areas of intense battering on one or more previously used margins. The latter were discarded because they were too small and lack the specific gravity to function efficiently. Experimental (Flenniken et al. 1993) and ethnographic data (Bartlett 1933; Hayden and Nelson 1981; HiU 1982; Hough 1897; Lange 1959; Michelsen 1967; Simpson 1952) document ground stone tools, mainly manos and metates, were manufactured, sharpened, and resharpened with battered implements (Flenniken et al. 1993). The sample of twenty-two battered implements and nineteen battered implement flakes demonsttates that manos and/or metates were resharpened at CA-SDI- 8694. PJ. 4-04 4-30 August 2005 4.6 GROUND LiTHic ARTIFACTS 4.6.1 Introduction All ground stone materials recovered from CA-SDI-8694 were selected for analysis and interpretation. Ground stone implements may include a wide range of objects used to or created by tiie processes of abrasion, impaction, or polishing (Adams 2002). Often, ground stone tools are associated with the processing/milling of seeds, nuts (i.e., acoms, walnuts, holly leaf cherry), and tiie processing of small mammals. In addition, ethnographic evidence indicates that bone, clay, and pigments may have also been processed with the same tools (Gayton 1929; Kroeber 1925; Spier 1978). Implements of this type may be identified by the pattem of wear developed through milling stone against stone. This process often resuhs in a smooth and/or polished surface, depending on the substance ground and the lithic material type. Often these surfaces are pecked or resharpened when ground too smooth. These implements are sometimes shaped into a desired form through pecking, grinding, or flaking. Thus, tool identification is based on the presence of ground or smooth surfaces, pecked or resharpened surfaces, and evidence of shaping of the tool form. The tools were separated into three groups: manos/metates, unidentifiable ground stone fragments, and battered implements. Unidentifiable ground stone is defined herein as a fragment of lithic material with a minimum of a single ground surface, but with no technologically identifiable characteristics to indicate tool form. 4.6.2 Manos A total of sixty-one manos were recovered during the present excavations at CA-SDI-8694. Ofthe total, twelve were complete, or nearly complete, and forty-nine were fragmentary. The majority of manos recovered are granitic cobbles (n=40), followed by cobble volcanics (n=20), and quartzite (n=l), with bifacial use-wear (n=51) predominating the collection. Three manos recovered at CA- SDI-8694 show evidence of shaping, such as pecking, flaking, and end-battering suggesting extended use. This extended usage and mano curation may imply long-term occupation ofthe site. There is end-battering present on two ofthe specimens. The end-battering visible on the specimens may indicate that the manos were also used as hammers to sharpen metate grinding surfaces when they became to slick to grind. The overall curvature of each mano face is slight (n=105), indicating that the opposing milling surface that the manos were ground against (i.e., metate, milling slick) was PJ. 4-04 4-31 August 2005 II s tt shallow in form. In addition, the grinding pattems evident on the faces of each mano indicate that the majority of manos (n=43) are basin manos used primarily in a reciprocal stroke manner in concert with shallow basin metates (Adams 2002)(Figure 4-5). All of the manos collected were thermally damaged to varied degrees. It is possible however, that some of the manos present were not used for grinding purposes at this site, but gleaned from other sites by the inhabitants of CA- SDI-8694 for use in rock hearth/earth ovens or that the manos were recycled at the site. However, this theory is less likely as there is a large quantity of battered implements at the site suggesting the use and maintenance of groimd stone tools at CA-SDI-8694. It is more likely that once manos became dull, or more friable after a period of use, they were cycled into use as rocks for fire hearths and/or earth ovens. In general, the ratio of manos to metates at a site where milling technology is present is much greater. It has been suggested that the reason for this is that manos wear out much faster than metates (Wright 1993), and thus more manos are produced as needed. The larger milling assemblage recovered from CA-SDI-8694 suggests that the site inhabitants depended on food packages that required milling for processing (i.e., grass seeds). It is evident that a large portion of the diet of the inhabitants of CA-SDI-8694 was derived from plant foods that required milling technology for consumption. 4.6.3 Metates Metates were identified based on the presence of at least one concave ground surface. Only block style basin-metates were identified within the present collection. In total, six metates/metate fragments were recovered from CA-SDI-8694, and include three granitic, two sandstone, and one volcanic. Slab metates in comparison to block metates may be considered portable. Block metates are too heavy to transport and are defined by Binford (1980) as "site fumiture." The presence of these large block metates may be evident of a longer period of site occupation. The six block metates recovered include one bifacial, three unifacial, and two unknown. The majority of specimens retain shallow td flat grinding surfaces. The flat basins retain a more planer grinding surface, and may have been used to process less oily products such as fibers (Kowta 1969), whereas the shallow basins may have been used for the processing of products such as hard seeds.

Four ofthe six specimens show evidence of pecking to rejuvenate the grinding surfaces. Some specimens in the collection were too fragmentary to identify. Three of the six metates display evidence of shaping in the form of pecking, flaking, and/or grinding generally around the outer circumference. Flaking and pecking would have acted to remove unnecessary mass, and aid in producing the desired shape. Final grinding may have helped to even the overall surface, but was not always necessary. All ofthe metate fragments recovered were thermally damaged. It is possible however, tiiat some oftiie metate fragments were recycled for use in rock hearths and/or earth ovens. 4.6.4 Ground Stone Fragment Eighteen ground stone fragments were identified in the present collection. A ground stone fragment is a piece of ground stone implement that has some grinding, but lacks any defining attributes that would facilitate tool identification. The majority of fragments recovered from CA-SDI-8694 are granitic (n=16), in addition to one volcanic, and one schist ground stone specimen. As with the manos recovered from the site, all of the ground stone fragments are thermally damaged. 4.6.5 Shaped Stone Specimen CA-SDI-8694-145 is semi-cylindrical in form, and exhibits polish around the circumference. The granitic specimen fragment measures 51.7x48.9x30.7 mm, with a weight of 132 g. The use ofthe artifact is undetermined. 4.7 CERAMIC ANALYSIS (by Monica Guenero) 4.7.1 Introduction As a result ofthe cunent stiidy, a total of 260 sherds were recovered from site CA-SDI-8694. All sherds were not included in the ceramic analysis, as some were too small to obtain a thin-section sample. A total of 252 sherds from CA-SDI-8694 were included for sample selection. Ceramic sherds were first placed into different sample groups based upon mica (biotite and muscovite) concenfration, sherd thickness, rim shape variability, surface color, and core color. Sherds with recent broken edges were checked to see if they mended with other sherds witiiin the sample group. PJ. 4-04 4-34 August 2005 Both procedures reduced the possibility of analyzing sherds from the same parent vessel. At site CA-SDI-8694,15 different sample groups were identified. After all the sherds had been placed into different sample groups, each group was placed into plastic bags and a random sherd was selected as the representative sample for each group. Sixteen ceramic sherds from CA-SDI-8694 were submitted to the San Diego Pefrographics Laboratory, in Escondido, Califomia, for the creation of thin-section samples. Each sherd was enveloped in epoxy resin, then polished and cemented to a glass slide. The sample was tiien cut and pohshed to a thickness of 30 microns (pm), and sealed with a glass-cover slip. Once the thin-section samples, along with what remained of the ceramic sherds, were retumed to Gallegos & Associates laboratory, they were analyzed for mineral composition. Each thin-section sample was examined under a polarizing (pefrographic) microscope by ttansmitted light (plane-polar and cross-polar) from 28X to 1500X magnifications. Important mineral characteristics that were considered when examining the thin sections include distinctive cleavage, twinning, alteration, zoning, exsolution, or the presence of inclusions. For a discussion of ceramic wares in the San Diego region see Section 2.5.2.1. 4.7.2 Results A total of 260 ceramic sherds were recovered during the data recovery of site CA-SDI-8694, however, only 252 sherds were included in the study sample since 8 of the sherds are highly fragmented, and range from less than 1 cm in length. A representative sample of ceramic sherds from site CA-SDI-8694 were thin-sectioned, and analyzed under a polarizing (pefrographic) microscope to identify specific mineral inclusions and their conesponding geologic locales. Pefrographic thin-section analysis was conducted on 16 ceramic sherds. Results of this analysis indicate that 70%) (n = 177) of tiiese sherds are Tizon Brown Ware, 25% (n = 63) are Salton Brown Ware, and 5% (n = 12) are Lower Colorado Buff Ware (Table 4-4). The presence of the Lower Colorado Buff Ware ceramics indicates that frade and/or fravel occuned to the former lake bottoms and alluvial deposits in the Lower Colorado Desert and Imperial County (near ancient Lake Cahuilla). The presence of Salton Brown Ware suggests that frade and/or fravel occurred to the east PJ. 4-04 4-35 August 2005 I Table 4-4 Thin Section Results for CA-SDI-8694* Plagioclase Biotite Muscovite Cat.

As site CA-SDI-8694 is located in a coastal area, trade and/or ttavel inland, and/or to mountain regions occuned for procurement of mountain clays. A total of six rim sherds were identified, examined, and profiled. Table 4-5 provides the diameter of the vessel opening for six rim sherds and Figures 4-6 and 4-7 illusfrate the orientation ofthe vessel mouth for the six profiled rim sherds. Vessel openings for the six rim sherds range from 8 cm to 14 cm in diameter with a medium diameter of 11 cm. Rim thickness ranges from 4 mm to 7 mm with medium thickness of 5.5 nun. Four ofthe rim sherds are recurved, while two rims are tapered. Three ofthe rim sherds have rounded lips, two rims have flat lips, and one rim has a beveled lip. The rim sherds are too small to determine the shape of the body vessel, and therefore the overall shape ofthe parent vessel was not established. Previous work by Hagstiiim and Hildebrand (1990) and Gallucci (2001) suggests that average rim diameters that fell within a range of 20 cm to 25 cm were regarded as cooking bowls. The rim diameters ofthe six rim samples from site CA-SDI-8694 fall well below this range (8 cm to 14 cm), indicating that the parent vessels had much smaller vessel openings. Smaller vessel openings may suggest that the parent vessels were small to medium in size, and/or the vessel openings were resfricted. Restricted vessel openings are possible indicators of fransport activities rather than cooking activities, given that smaller vessel openings prevent contents from spilling out. Rice (1987) observed two conditions that are necessary for the fransport of pottery over long distances. First, a pot should have a restiicted opening to prevent the contents from spilling out, and second, the pot should not be too heavy to hold and carry over long distances. Rice's (1987) two criteria appear to pertain to the ceramics at site CA-SDI-8694, as the rim sherds from this site may represent small vessel openings, and/or small vessels indicating possible transport activities. Sherds that exhibit a heavy soot deposit or heavy blackening/crystallization crast on the exterior (fire exposure) or interior (bumed contents) are clues that the parent vessels from which these sherds came from were likely used for cooking activities, as they contain bumed residue and evidence of repeated fire exposure (Rice 1987).

Approximately eight sherds have a heavy black crast on their interior. In addition to transport activities, pottery was most likely used for cooking activities at site CA-SDI-8694. 4.8 SHELL ARTIFACT ANALYSIS (BY TRACY STROPES) 4.8.1 Introduction For San Diego County, a processual understanding of manufacture, distribution, and use of shell artifacts has not been achieved. In addition, the range of morphological types of beads used in the San Diego region is not well understood. In contiast to other regions of Califomia, there is little information conceming the process by which shell artifacts were manufactured and used, or the evolutionary changes these artifacts may have gone through over time. The analysis of shell artifacts from other regions of Califomia (most notably the Chumash culture area) has demonsfrated considerable anthropological value in the understanding of prehistoric economies, trade systems and networks, and the organization of wealth and status in prehistoric societies (Fenenga 1988). For these regions, particular styles of shell artifacts have been established as chronologically diagnostic in a number of archaeological sites. The shell artifact assemblage from CA-SDI-8694 consists of a single Olivella sp. shell bead. 4.8.2 0/ive//fl sp. Shell Bead A single Gifford Type F5 spire-lopped Olivella sp. shell bead was identified in the present collection. The bead was recovered from the 20-30-cm level of Unit 38. It should also be noted that the present specimen was not identified in context with any identifiable cultural features and appears to be randomly distributed within the site. The specimen is a whole shell that has the spire end modified by breaking or grinding to produce a hole for sfringing or attaching. This type of bead is the simplest and most easily produced form of shell bead. In general, whole Olivella sp. beads are not considered to be reliable time markers throughout Califomia. However, spire-lopped/ground Olivella sp. beads are likely the oldest form of shell bead known from Califomia (Fenenga 1988). Evidence from CA-SDI-11079 in Otay Mesa, Califomia suggests the employment of Olivella sp. shell for beads as early as 9,000 years ago (Kyle et al. 1998), and ethnographic evidence PJ. 4-04 4-41 August 2005 demonstrates that their use continued throughout historic times (Howard 1974; Dietz and Jackson 1981; Roop and Flynn 1978). 4.9 INVERTEBRATE FAUNAL ANALYSIS 4.9.1 Introduction Invertebrate remains recovered from the 44 1x1-m excavation units at CA-SDI-8694 totaled 76,492.08 g. All shell recovered was identified to species, order, and class. A total of 25 species, 4 orders, and 3 classes of invertebrate remains were identified within the 44 analyzed units. These shellfish species were representative of three marine environments: bay/lagoon/estuary; rocky shore/outer coast; and sandy beach. 4.9.2 Methods Each shell was weighed and examined to identify genus and species. All shell was speciated in order to determine habitat exploitation pattems and to obtain paleo-environmental data. 4.9.3 Results The majority of the 76,492.08 g of invertebrate remains was recovered from the 0-40-cm levels, decreasing in quantity from 40-50 cm, and becoming negligible from 50-60 cm (Table 4-6). The primary concentration of shell was located in the northwest portion ofthe site. Ofthe 76,492.08 g of sheU recovered, 70,685.56 g were identifiable to species. The remaining 5,806.52 g were determined to be too fragmentary or weathered for proper identification. Table 4-6 illustrates, that the majority of the identifiable shellfish species recovered from the 44 units were Chione sp. (71.3%)), Argopecten sp. (19.4%), Ostrea lurida (7.2%), znd Polinices sp. (0.9%)(Figure 4-8). The remaining species from the site contributed to less than two percent ofthe total specimens. This indicates a primary exploitation focus on bay/lagoon/estuary habitats by the inhabitants of CA- SDI-8694. Table 4-7 lists the species identified and their habitats. The majority of invertebrate remains were gathered from bay/lagoon/estuary environments (98.9%)), followed by rocky PJ. 4-04 4-42 August 2005 Table 4-6 CA-SDI-8694: Total Invertebrate Faunal Remains by Depth Depth (cm) Species 0-10 10-20 . 20-30 30-40 40-50 50-60 Total Argopecten 2386.95 2592.41 3907.8 3559.9 1268 0 13715.06 Astraea undosa 48.1 28.1 73.4 10.8 6.4 0 166.8 Balanus 2.7 1.3 4 2 0 0 10 Cerithidea 2.7 2.8 2.4 1.2 0 0 9.1 Chione 13868.7 12765.5 11614.1 8807.5 3375.1 0 50430.9 Chiton 12.3 9.5 10.4 4.8 1.2 0 38.2 Collisella scabra 0 0 1.3 0 0 0 1.3 Crepidula 7.1 7.3 4.7 1.8 3.1 0 24 Crepipatella lingulata 0.5 0 0.2 0 0 0 0.7 Donax gouldii 63.3 57.1 50.5 29 6.9 0 206.8 Haliotis 67.2 7.1 0 0 0 , 0 74.3 Lottia gigantea 1.4 0 0 0 0 0 1.4 Malatoma 0 0 0.6 0 0 0 0.6 Modiolus 1.2 0.9 8 0 0 0 10.1 Mytilus 10.3 36 17.3 15.7 9.9 0 89.2 Olivella biplicata 2.6 0.6 2.7 1.6 0 0 7.5 Osttea lurida 1375.2 1450.2 1131.9 884.7 231.3 0 5073.3 Petaloconchus montereyensis 0.1 0 0 0 0 0 0.1 Polinices 136.4 157.8 276.5 65.2 29.8 0 665.7 Pseudochama exogyra 24.9 d 21 0 0 0 45.9 Pteropurpura festiva 0 3 0 2.7 0 0 5.7 .

In summary, the invertebrate shell data suggests that the inhabitants of CA-SDI-8694 primarily exploited bay/lagoon/esttiary habitats for shellfish. However, tiiere is some evidence of exploitation of rocky shore/outer coast and sandy beach habitats as well. It is likely that this exploitation pattem represents a focus on primarily a single environment, with opportunistic gathering near rocky shore/outer coast and sandy beach locations. The radiocarbon dates support this exploitation pattem. Given the resuhs of shellfish analysis for CA-SDI-8694, the inhabitants likely exploited the nearest lagoon habitat (Agua Hedionda Lagoon), and occasionally visited other nearby shoreline areas. 4.10 VERTEBRATE FAUNAL ANALYSIS (by Patricia Mitchell) 4.10.1 Introduction The bird, mammal, reptile, and fish bone coUection from site CA-SDI-8694 consists of 1,036 fragments with a combined weight of 167.9 g. Ofthe 1,036 fragments, 33 (4.5 g) were detennined to be intiiisive to the prehistoric site. These 33 bone fragments exhibit signs of intiiisiveness such as oily texttire, or fragile, whole elements. The oily textiire suggests the presence of collagen in the bone, and therefore, the bones are most likely the result of a recent, natiiral death, and were not included in the following data tabulations. The remaining 1,003 (163.4 g) bone fragments were recovered from the 0-60-cm levels of 39 excavation units. All bone fragments were identified to class, order, family, or when possible to genus and species. Seventeen animal species were identified and included Canis latrans (coyote), Clemmys marmorata (southwestem pond turtle), Galeorhinus zyopterus (soupfin shark), Genyonemus lineatus (white croaker), Lepus califomicus (black-tailed jackrabbit), Myliobatis californica (bat ray), Odocoileus hemionus (mule deer), Paralichthys califomicus (Califomia halibut), Rhinobatos productus (shovelnose guitarfish), Roncador stearnsii (spotfin croaker), Sarda chiliensis (Pacific bonito), Semicossyphus pulcher (Califomia sheephead), Spermophilus beecheyi (Califomia ground squirrel), Sylvilagus audubonii (desert cottontail), Sylvilagus bachmani (brash rabbit), Thomomys bottae (Botta's gopher), and PJ.4-04 4-46 August 2005 16000 2000 Figure 4-9 CA-SDI-8694 Companson of Major Species by Depth 30 Depth (cm) 40 50 - Argopecten - Chione -Donax gouldu • Ostrea lunda I I I I I I I I 1 I tt Thunnus alalunga (albacore). The remaining bone fragments lacked the morphological features that would have allowed them to be identified to a taxonomic category greater than their class. Other categories used to identify these fragments include medium bird, elasmobranch, teleostei, snake, small mammal, medium mammal, and large mammal. Evidence of buming and butchering was present on a portion ofthe collection and has allowed for some interpretation ofthe preparation of the meat portion of the inhabitants' diet at site CA-SDI-8694. Five bone artifacts were also recovered from the site and are discussed in Section 4.10.6. 4.10.2 Methods Each bone was examined to determine: • element • right or left side • highest taxonomic category • evidence of buming, and if so, what degree of oxidation • evidence of butchering, and if so, what method of butchering Comparative skeletal collections used in the identification process included those from Scripps Institute of Oceanography, as well as from private collections and a photographic database. Bone atlases (Can 1952; Lawrence 1951; Nickel et al. 1986; Olsen 1985; Sandefiir 1977; Schmid 1972) supplemented the analysis. Categories used in this analysis include: Bumed: Bone elements or fragments that show color change from exposure to heat or fire (oxidation). Colors may include: • brown = exposure to heat, but little or no exposure to open flames. • black = direct exposure to open flames (i.e., roasting or discard in a fire). PJ. 4-04 4-48 August 2005 • blue/white (calcined) = direct exposure to a fire hotter than 800° Celsius (Ubelaker 1978). This may represent bone that was severely bumed during preparation, in which case, if flesh was present on the bone during exposure to the fire the bone would exhibit signs of warping and shrinking (Ubelaker 1978). Calcined bone may also be the result of having been discarded in a fire hearth (Wing and Brown 1979). Unbumed: No evidence of buming or oxidation. Butchered: Bone with evidence of processing by slicing or chopping actions. Bfrd: Bones that have thin walls in cross-section, are hollow, and light in weight. These are often distinguishable from mammal bone because tiiey contain large cavities that would have been filled with air in life. Small Mammal: All nondiagnostic vertebrate fragments, whose sizes are between a mouse and a jackrabbit. Medium Mammal: All nondiagnostic vertebrate fragments, whose sizes are larger than a jackrabbit, but smaller than a deer. Large Mammal: All nondiagnostic vertebrate fragments, whose sizes are deer-size and larger. Elasmobranch: Dram-shaped vertebra that are from cartilaginous fish (rays/skates, shark). Teleostei: Funnel-shaped vertebrae with/without the spinous process attached, and other skeletal elements considered as bony fish. The quantification of faunal material can be sttidied using several methods. The methods used in individual sttidies are usually detennined by sample size and type of site being investigated. Two methods were used in this study: the number of identified specimens per taxon (NISP), which represents the total number of specimens within a category; and the minimumnumber of individuals (MNI), which represents the minimum number of individuals within a genus and species category. 4.10.3 Results The animal remains recovered from all units contaming bone (39 excavation units) consisted of 1,003 (163.4 g) bone elements from tiie 0-60-cm levels ofthe site (Tables 4-8 and 4-9). Seventeen animal species were identified from 71 (5.3%) pieces of bone and include Canis latrans (coyote), Clemmys marmorata (soutiiwestem pond turtle), Galeorhinus zyoptems (soupfin shark).

The remaining 932 bone fragments lacked the morphological features tiiat would have allowed them to be identified to the genus and species level, and were therefore identified as medium bird, elasmobranch, teleostei, snake, small mammal, medium mammal, or large mammal. Horizontal distribution of NISP counts presented in Table 4-8 shows that the majority of bone elements were recovered from Units 15 and 35 (10.3% each), followed by Units 33 (8.0%), 32 (6.3%)), 14 (5.6%), and 24 (5.0%). The remaining 33 units contiibuted less than 5% each. Table 4-9 presents the resuhs ofthe vertical distiibution of NISP counts of the 39 units. There is a steady increase of vertebrate remains recovered from the surface to the 20-cm levels (NISP=212 to NISP=-330). The NISP counts then begin to decline from the 20-cm level to the 60-cm level (NISP=330 to NISP=3). The majority of bone fragments (98.1%) combined) were recovered from the 0-40-cm levels, with the greatest concenfration in the 10-30-cm levels (63.0%)). Table 4-10 presents the total NISP and MNI (when possible) for each genus and species identified. A minimum total of 25 animals were represented in the collection. The fish species represented 11 ofthe 25 animals \dQnt\f\Qd (Roncador steamsii, MNI=3; and Galeorhinus zyopterus, Genyonemus lineatus, Myliobatis californica, Paralichthys califomicus, Rhinobatos productus, Sarda chiliensis, Semicossyphus pulcher, and Thunnus alalunga, MNI=1 each). The tenestiial small mammal species (Sylvilagus audubonii, MNI=3; Lepus califomicus, MNI=2; Sylvilagus Bachman, MNI=2; Thomomys bottae, MNI=2; and Spermophilus beecheyii, MNI=1) were the next most abundant and represented 10 of the 25 animals. Clemmys marmorata had a MNI=2, and terresfrial medium mammal (Canis latrans) and large mammal (Odocoileus hemionus) each had a MNI=1.

The remaining animal resources contributed much less to the meat portion of the inhabitants' diet: large mammal resources were 19.9%; fish resources were 6.0% each; medium mammal resources were 3.0%; reptile resources were 1.0%); and avian resources were less than 0.1%. As seen in Table 4-11, evidence of buming was present on the majority ofthe bone collection (63.9%)). Ofthe 641 bumed bones, 92.7% (n=594) were bumed brown in color, indicating exposure to heat, but not to a direct flame. This suggests that these animals were likely cooked in some type of container (i.e., pottery, stone, basketiy). Dracker (1937) noted that the bones of small mammals and the meat were pulverized, and that heated stones were used in baskets for cooking (stone boiling) by the Luisefio Native Americans, Animal species or categories bumed brown in color include Canis latrans, Clemmys marmorata, Galeorhinus zyopterus, Genyonemus lineatus, Lepus califomicus, Myliobatis californica, Odocoileus hemionus, Paralichthys califomicus, Rhinobatos productus, Sarda chiliensis, Semicossyphus pulcher, Spermophilus beecheyi, Sylvilagus audubonii, Sylvilagus bachmani, Thomomys bottae, Thunnus alalunga, medium bird, elasmobranch, teleostei, snake, small mammal, medium mammal, and large mammal. The bones that were bumed black in color represent 3.1% (n=20) ofthe bumed specimens. The coloring suggests that these bones were bumed during roasting, or they were discarded in a fire hearth. Wing and Brown (1979) suggest that this type of charring is usually confined to the exposed ends of bone. This type of charring was not identified on any of the bones bumed black in color. It is likely that the specimens chaned black were the resuh of being discarded in a fire hearth. Animal sjpecies or categories charred black in color include small mammal and large mammal. The specimens that were calcined (n=27; 4.2% ofthe bumed elements) were exposed to a direct flame at exttemely high temperatures (greater than 800° Celsius). Only one ofthe calcined bones exhibited signs of shrinking or warping. These are attiibutes that indicate the presence of soft tissue PJ. 4-04 4-54 August 2005 Table 4-11 CA-SDI-8694: Summary of Bumed Bone Specimen Brown Black Calcined Total Percent Overall Total Bumed Canis latrans 1 0 0 1 100.0% 1 Clemmys marmorata 3 0 0 3 50.0% 6 Galeorhinus zyopterus 4 0 0 4 100.0% 4 Genyonemus lineatus 2 0 0 2 50.0% 4 Lepus califomicus 2 0 0 2 50.0% 4 Myliobatis californica 2 0 0 2 66.7% 3 Odocoileus hemionus 1 0 1 2 66.7% 3 Paralichthys califomicus 1 0 0 1 100.0% 1 Rhinobatos productus 3 0 0 3 100.0% 3 Roncador stearnsii 0 0 0 0 0.0% 3 Sarda chiliensis 1 0 0 1 100.0% 1 Semicossyphus pulcher 6 0 0 6 66.7% 9 Spermophilus beecheyi 1 0 0 1 100.0% 1 Sylvilagus audubonii 8 0 0 8 57.1% 14 Sylvilagus bachmani 6 0 0 6 66.7% 9 Thomomys bottae 4 0 0 4 100.0% 4 Thunnus alalunga 1 0 0 l' 100.0% 1 Large Mammal -130 6 16 152 77.6% 196 Medium Mammal 22 0 1 23 79.3% 29 SmaU Mammal 388 14 9 411 61.3% 671 Elasmobranch 1 0 0 1 100.0% 1 Teleostei 5 0 0 5 16.7% 30 Medium Bfrd 1 0 0 1 100.0% 1 Snake 1 0 0 1 25.0% 4 Total 594 20 27 641 63.9% 1003 Percent 92.7% 3.1% 4.2% 100.0% fl I on the bone at the time of exposure to an open flame.

Animal species or categories calcined include Odocoileus hemionus, small mammal, medium mammal, and large mammal. 4.10.4 Butchered Bone Four bones had cut marks suggesting butchering. All of the bones were large mammal specimens, tiiree of which were bumed (brown in color). All four specimens were chopped, possibly to exfract manow. These cut marks were wide, deep marks with evidence of chipping ofthe cortical bone that surrounds the impact point. 4.10.5 Natural History Tenestrial There are three species of Leporidae represented in the vertebrate collection: Lepus califomicus (black-tailed jackrabbit), Sylvilagus audubonii (desert cottontail rabbit), and Sylvilagus bachmani (brash rabbit). Jackrabbit is found only in open or partially open areas (Bond 1977), and is most active in the moming and early evening. They feed on green vegetation, shrabs, and cacti (Russo and Oldhausen 1987). According to Christenson (1986), jackrabbit is best hunted with nets. Dracker (1937) also noted that rabbits were hunted in communal drives and driven into nets. Desert cottontail can be found in open plains, foothills, low valleys, and coastal areas, and are easily caught with a rabbit stick or bow and anow (Christenson 1986). They are most active in early moming, late aftemoon, and at night. Their diet consists of green vegetation and fhiit (Russo and Oldhausen 1987). Brash rabbit can be found in areas of thick brash. It is primarily noctumal, and does not dig bunows. When pursued, the brash rabbit will more often go into low brash for protection rather than retreat into another animal's bunow (Whitaker 1980). All three Leporidae were probably hunted for food as well as for their pehs (Schroth and Gallegos 1991). Two rodent species were identified in this collection, and both species are native to San Diego Coimty. Spermophilus beecheyi (Califomia ground squinel) and Thomomys bottae (Botta's pocket gopher) can be found in areas ranging from the mountains to the coast. The ground squinel, like the PJ. 4-04 4-56 August 2005 n fl fl fl tt gopher, is a bunowing animal. It is active from dawn until dusk, and while it may climb into brash or trees it usually remains on the ground. The gopher is the most common and widespread rodent, occurring wherever there is vegetation and loose dirt to bunow through (Bond 1977). Odocoileus hemionus (mule deer) is native to the westem half of the United States, most of Canada, and northem Mexico. It feeds on shrabs, twigs, grasses, and herbs in several types of habitats, such as coniferous forests, desert shmbs, chapanal, and grasslands with shrabs. Mule deer is most active in the moming and the evening, and occur singly or in small groups (Burt and Gossenheider 1976). Ethnographic data states that hunters would disguise themselves with the head and fnr of a deer when stalking other deer (Ashby and Winterboume 1966; Christenson 1981), and the usual weapon used to kill deer was the bow and arrow, but the use of snares has also been documented (Sparkman 1908). The killed deer was useful for items such as the meat, hide, and hoof (for ratties). Canis latrans (coyote) is native to most of the United States (Booth 1950), and is found in San Diego County in the Upper and Lower Sonoran life-zones (Bond 1977). Coyotes are primarily noctumal, but can be active at any hour. Their dens are usually located along river banks, canyons, and gulches. They are omnivorous, but their diet consists mostiy of small mammals (Russo and Oldhausen 1987). Dracker noted that the Luisefio avoided eating coyote (1937), and the coyote bone recovered from the site is a claw so it is not certain that they actually consumed coyote at this site. Reptile Clemmys marmorata (southwestem pond turtle) once ranged from Monterey Bay to northem Baja Califomia, from coastal drainages to foothills, and even to the desert slope of the Mojave River (by the San Bemardino Mountains)(Bond 1977). The southwestem pond tiirtle hibemates through winter and emerges in March (Carr 1978). The diet of the southwestem pond turtle consists of aquatic plants, insects, and carrion (Schneider and Everson 1989). "Turtle" uses include meat consumption, ceremonial use (rattles), medicinal use, technological uses including ladles, scoops, bowls, and containers, and symbolic uses in Native American artwork and oral ttaditions. PJ. 4-04 4-57 August 2005 I Marine Fish Galeorhinus zypoterus (soupfin shark) is a common epipelagic shark along the Califomia coast. It ranges from San Juanico Bay in Baja Califomia to northem British Colombia. It can grow to 6.5 ft. in length (MiUer and Lea 1972). Genyonemus lineatus (white croaker) is a common fish along the southem Califomia coast. It ranges from Magdalena Bay in Baja Califomia to Vancouver Island, B.C. (Miller and Lea 1972). It occupies all ofthe soft subsfrate habitats, but less so in the kelp beds and the deep rock reefs (Allen 1985). Myliobatis californica (bat ray) is a common fish that can be found in bays and sandy shallow areas to a depth of 150 ft. anywhere from the Gulf of Califomia to Oregon (Miller and Lea 1972). It can weigh up to 210 lbs. and have a width of 4 ft. (Miller and Lea 1972). Paralichthys califomicus (Califomia halibut) is a common fish along the southem Califomia coast and can be found from the surface to 300 ft. in depth. It ranges from Magdalena Bay in Baja Califomia to the Quillayute River in British Columbia (Miller and Lea 1972). It can be found in harbor/nearshore soft bottom habitats, and to a lesser degree bay/estiiary environs (Allen 1985). Rhinobatos productus (shovelnose guitarfish) is a common fish along the Califomia coast that ranges from the Gulf of Califomia to as far north as San Francisco, and can be found from the surface to a depth of 50 ft. (Miller and Lea 1972). It can be found in harbor/nearshore soft bottom habitats, and to a lesser degree bay/estuary environs (Allen 1985). Roncador steamsii (spotfin croaker) is a common fish along the soutiiem Califomia coast. It ranges from Mazatlan, Mexico to Point Conception, and includes tiie Gulf of Califomia (Miller and Lea 1972). It occupies open coast sandy beach habitats with seasonal occurrences in the bay/esttiary environment during the spring and summer (Allen 1985). PJ. 4-04 4-58 August 2005 Sarda chiliensis (Pacific bonito) is a common fish along tiie Califomia coast. It ranges from Chile to the Gulf of Alaska (Miller and Lea 1972). It is a nearshore pelagic species that occupies midwater habitats including deeper rock reefs and kelp beds (Allen 1985). Sardinops sagax (Pacific sardine) is a common fish along the southem Califomia coast. It ranges from Guaymas, Mexico to Kamchatka (Miller and Lea 1972). It is a nearshore pelagic species tiiat occupies midwater habitats (Allen 1985). Semicossyphus pulcher (Califomia sheephead) can be found from Cape San Lucas in Baja Califomia to Monterey, Califomia. They can be 3 ft. long and weigh up to 36 lbs.. They occur from the surface to 180 ft. (Miller and Lea 1972), and can be found in shallow and deeper rock reef and kelp bed environments (Allen 1985). Thunnus alalunga (albacore) is a common epipelagic fish along the Califomia coast. It ranges from Guadalupe Island to southeast Alaska. It can weigh as much as 93 lbs., but in Califomia only as much as 76 lbs. (Miller and Lea 1972). 4.10.6 Bone Artifacts Five bone artifacts were recovered from the site. Gifford's 1940 publication was used to assign a typological category when possible. Two bone awl fragments, one possible awl/composite .fishhook/fishing toggle fragment, a drilled fish vertebra, and a possible otolith pendant or charm were identified in the collection. The artifact assumed to be more likely a barb fragment for a composite fishhook or a fishing toggle rather than an awl fragment was identified based on its morphology and lack of use-wear near the tip. The presence offish remains in this faunal collection makes this a more plausible classification. Table 4-12 lists each artifact, its provenience, and type. Awls Artifact CA-SDI-8694-301 was a tip fragment of an awl recovered from the 10-20-cm level of Unit 25 was assigned with Gifford's Type Ale (1940). The tip fragment was manufactured from a PJ. 4-04 4-59 August 2005 Table 4-12 CA-SDI-8694: Bone Artifact Summary Artifact Unit Level Artifact Type Gifford Typology 301 25 10-20 cm Awl tip fragment Ale 514 45 10-20 cm Awl fragment - tip missing Albll 83 11 20-30 cm Awl/Toggle/Composite Fishhook Ale/U/00 348 41 0-10 cm Drilled Vertebra CC5 628 33 20-30 cm Otolitii Pendant/Charm ? splinter of a large mammal bone. It had been bumed (brown in color), shaped, and highly polished (Figure 4-10). There were no use-wear striations or designs on the artifact, but there was a "tell- tale" chip on the tip ofthe fragment. This chip has been observed over the years by the author on other awl tips, and is assumed to be the result of pressure applied to the tip. The second fragment (specimen CA-SDI-8694-514) recovered from the 10-20-cm level of Unit 45 was assigned with Gifford's Type Albll (1940). This mostly complete awl fragment (tip missing) was manufactured from a mule deer carmon bone with the proximal end used as the handle: It had been slightly bumed (brown in color), shaped, with little polished near the tip (see Figure 4-10). There was evidence of diagonal use-wear striations, but they were mostly obscured by the presence of rodent gnaw marks. Artifact specimen CA-SDI-8694-83 was either a fragment of an awl, a fishing toggle, or a composite fishhook. It was recovered from the 20-30-cm level of Unit 11, and was assigned with Gifford's Type Ale, U, or 00 (1940). The fragment was manufactured from a splinter of a large mammal bone. It had been bumed (brown in color), shaped, and polished (Figure 4-11). No use-wear sfriations were observed on the artifact. Artifact specimen CA-SDI-8694-348 was a biconically-drilled soupfin shark (Galeorhinus zyopterus) dorsal vertebra. It was recovered from the 0-10-cm level of Unit 41, and was assigned with Gifford's Type CC5 (1940). The fragment was manufactured from shark vertebra, and had no other modifications other than being drilled (see Figure 4-11). One other unmodified soupfin shark vertebra was recovered from a lower level in the same excavation unit. Artifact specimen CA-SDI-8694-628 was a white sea bass (Atractoscion nobilis) otolith that appears to have been Strang, possibly as a pendant or charm. It was recovered from the 20-30-cm level of Unit 33, and was not able to be assigned with a Gifford typological category. The otolith was larger and more decomposed than other otoliths recovered from tiie site, has use-wear lines around the lobe ofthe outer surface ofthe otolith, and both edges next to the lobe were notched fi-om wear (Figure 4- 12). No oth.Gr Atractoscion nobilis remains were present in this vertebrate collection.

Identification of the fish species was completed with the use ofthe fish collection at Scripps Institute of Oceanography in La Jolla, Califomia, which consists of 450 Pacific coast and deepwater specimens. The otoliths were first weighed (in grams) and measured (in millimeters). The process for analysis includes encasing the otolith in a clear resin matrix, then cutting it in half with a lapidary saw and buming the cut surface to better define the incremental lines. The cut surface was then examined under a stereoscopic microscope at lOX and/or 20X. The seasons are defined as: spring = mid-March through mid-May; summer = mid-May through early-October; and winter = mid-October through mid-March. 4.11.2 Results The four otolith specimens were identified as Genyonemus lineatus (white croaker) and Roncador stearnsii (spotfin croaker), and represented fish captured during the summer. The otoliths were recovered from the 0-20-cm levels of three units (Table 4-13). All four otoliths are from the left side, and therefore, represent four separate fish. 4.11.3 Natural History Genyonemus lineatus (white croaker) is a common fish along the southem Califomia coast. It ranges from Magdalena Bay in Baja Califomia to Vancouver Island, B.C. (Miller and Lea 1972). It occupies all of the soft subsfrate habitats, but less so in the kelp beds and the deep rock reefs (Allen 1985). Roncador stearnsii (spotfin croaker) is a common fish along the southem Califomia coast. It ranges from Mazatlan, Mexico to Pouit Conception, and includes the Gulf of Califomia (Miller and Lea 1972). It occupies open coast sandy beach habitats with seasonal occunences in the bay/estuary environment during the spring and summer (Allen 1985).

Specimen CA-SDI-8694-76 was collected from the 10-20-cm level of Unit 11, and is a Polinices sp. shell. Polinices sp. shell is often associated with Early Period sites, therefore this was selected to determine period of occupation, as this site is considered an Early Period site. In addition, Polonicies sp. specimens were sampled from CA-SDI-8797 (also thought to be an Early Period site) and CA-SDI-8303 (considered primarily a Late Period site) for comparison. The sample from CA-SDI-8694 provided a date (at two-sigma range) of BC 5550 to BC 5280 (Cal BP 7500 to 70). This date identifies occupation for CA-SDI-8694 within the Eariy Period. Specimen CA-SDI-8694-305 was coUected from the 40-50-cm level of Unit 25 and is a Chione sp. specimen. Chione sp. shell is associated with both Early and Late Period occupation, and this sample was selected to date the basal level ofthe deposit. The sample provided a date (at two-sigma range) of BC 4690 to BC 4450 (Cal BP 6640 to 6400). This date also identifies occupation of CA- SDI-8694 within the Early Period. Specimen CA-SDI-8694-606A was collected from the 30-40-cm level of Unit 40 and is a large Chione sp. specimen. Large Chione sp. shell is often associated with Early Period sites, therefore this specimen was selected to determine the age of the deposit. The sample provided a date (at two- sigma range) of AD 1000 to AD 1300 (Cal BP 950 to 650). This date identifies a Late Period occupation for.CA-SDI-8694. Specimen CA-SDI-8694-606B was collected from the 30-40-cm level of Unit 40 and is aDonax sp. specimen. Donax sp. shell is usually associated with Late Period sites, therefore this specimen was selected to directly compare to specimen CA-SDI-8694-606A. The sample provided a date (at two- sigma range) of AD 1690 to AD 1910 (Cal BP 260 to 40). This date also supports occupation for CA-SDI-8694 within tiie Late Period.

Given the radiocarbon dates, site CA-SDI-8694 was occupied during both the Eariy and Late Periods. 4.13 RESIDUE ANALYSIS Residue analysis was conducted by Robert Pan (CSUB) for two projectile point specimens recovered from CA-SDI-8694 (specimen CA-SDI-8694-189, and -303). A single positive reaction was registered for specimen CA-SDI-8694-303 (Table 4-15). The specimen reacted positively to deer antiseram indicating the presence of protein from any species of deer or elk. The positive reaction to deer antiseram may represent a few scenarios including the hunting of deer, or the use of parts ofthe deer to either create mastic to attach the point to a projectile shaft, and/or the use of sinew from the deer for the same purpose. The absence of identifiable proteins on the remaining specimen may be because of poor preservation of protein, insufficient protein, or that they were not used on any ofthe organisms included in the available antisera. 4.14 SITE SUMMARY The purpose ofthe data recovery program for CA-SDI-8694 was to adequately address mitigation of impacts through the completion of the collection of surface artifacts, field excavation of forty-four 1x1 -m units, artifact cataloguing, data analysis, and special studies. This work produced 4 bifaces, 5 cores, 1 piece of tested raw material, 8 nodule tools, 4 utilized flake tools, 4 steep-edged unifacial tools (SEUTs), 10 flakes from SEUTs, 2,367 debitage, 1 hammerstone, 22 battered implements, 19 flakes from battered implements, 61 manos/mano fragments, 6 metates/metate fragments, 18 ground stone fragments, 1 shaped stone, 260 ceramic fragments, 1 Olivella sp. shell bead, 2 bone awls, 1 bone fishing toggle, 1 bone bead, and 1 possible otolith pendant (see Table 4-1). Faunal material includes 76,492.08 g of shell, 4 otoliths, and 167.9 g of bone (see Table 4-1). Radiocarbon dating for CA-SDI-8694 places occupation of the site primarily during the Early Period (Middle Holocence) circa 5550 BC to 4450 BC. In addition. Late Period occupation is supported by two dates ranging from 90 to 950 years ago (1000 AD to 1910 AD), as well as by the presence of pottery PJ.4-04 4-69 August 2005 Table 4-15 Results for Protein Residue Analysis for CA-SDI-8694 Specimen No. Cultural Material Results 8694-189 Biface Negative 8694-303 Biface Deer and small projectile points. As demonsttated by the dates recovered from the site and the artifact assemblage, CA-SDI-8694 is a multi-component site with evidence of both Early and Late Period occupations. Disturbance from constraction, agricultiiral activities, and bioturbation was noted in all units. The range of artifacts at CA-SDI-8694 indicates a habitation/village site occupied at a minimum from May to October (based on availability of animals and otolith analysis). Flake production from local cobbles identifies flake tool use. Most likely, these tools were manufactured and used at the site. Lithic technology was primarily based on the nodule core reduction ttajectory witii evidence of adze (SEUT) production and maintenance, as well as the maintenance of milling tools. The presence of biface production and/or maintenance was niinimal. Hunting activities may have occuned near this site, as indicated by the presence of two projectile points. In addition, the large number of fish remains suggests a range of maritime activities performed by the inhabitants of CA-SDI-8694. The presence of 85 ground stone tools, and 21 battered implements represents processing of floral and faunal material through pounding and/or grinding. The presence of shellfish remains from primarily a lagoon habitat, and the diversity of the vertebrate faunal assemblage (mammal, fish, avian, and reptile) demonsfrate the range of foods collected, hunted, and processed at CA-SDI-8694. PJ. 4-04 4-71 August 2005 SECTIONS INVESTIGATIONS AT CA-SDI-8797 Locus C 5.1 PREVIOUS WORK Site CA-SDI-8797 (SDM-W-16) was originally recorded by Rogers circa 1920 as an occupation site (300x100 ft.) with cobble hearths. Rogers noted large quantities of Donax sp. shell in a portion of the site midden. Subsequent surveyors (Gardner 1981; Gross et al. 1987) re-recorded this site. A portion of CA-SDI-8797, located outside of the cunent study, area to the west, was tested by Gallegos and Huey (1992). This test identified a cultural deposit to 80 cm, and included recovery of debitage, i^ores, ground stone, a scraper, ceramics, a biface fragment, a shell bead, an otolith, modified bone, and shell (see Figure 1-6 and Table 1-4). An additional portion ofthe site located outside the cunent study area to the south and east was tested by Gallegos and Harris (1995). This test included excavation of 21 shovel test pits (STPs) and two Ixl-munits (see Figure 1-6 and Table 1-4). Both studies identified portions of the site as significant. A testing program conducted by Gallegos & Associates (Gallegos et al. 1999) included the excavation of nine STPs and one 1x1-m unit. Cultural material recovered includes 211 debitage, 19 manos, 5 ground stone fragments, 4 flake tools, 3 metate fragments, 3 pesties, 1 core, 1 ochre grinder, 2,470.8 g of shell, and 10.2 g of bone (see Figure 1-6 and Table 1-4). A fragment of human bone was recovered from the Ixl-m unit, and was reburied by Luiseno Native Americans (Gallegos et al.l999). Asphaltum and an asphaltum-covered stone were also recovered. The artifacts were of primarily local lithic material, however, debitage of non-local lithic material consisting of 2 pieces of white chert, 2 pieces of Monterey chert, and 1 piece of Piedra de Lumbre "chert" from the Camp Pendleton area were also recovered. The artifacts and faunal remains recovered from previous work (Table 5-1) identify CA- SDI-8797 as a habitation site, and demonsfrate a range of activities including shellfish processing, animal and plant processing, tool production, and tool kit maintenance. Based on radiocarbon dates, the occupation of the site was identified to circa 5,000 years ago.

The purpose of the Indexing and Preservation Study was to provide an index sample representing the deposit being capped, protected, and avoided of impacts. The cunent fieldwork resulted in the collection of337 debitage, 2 cores, 1 flake tool, 1 steep-edged unifacial tools (SEUT), 17 flakes from SEUTs, 2 battered implements, 4 manos, 1 ground stone fragment, and 1 polished stone. Faunal material includes 8.4 g of bone and 2,353.4 g of shell (Table 5-2). 5.2.1 Surface Collection A surface collection was completed to ensure that exposed surface artifacts were collected before capping activities are conducted. One battered implement was collected during the surface collection (see Table 5-2). 5.2.2 Unit Excavation A total of six 1x1-m units were excavated at CA-SDI-8797 Locus C. Unit selection was based on random sampling within the primary site area. Soil sfratigraphy for the units excavated for this study conformed to primarily a single depositional pattern across the site (Figure 5-2). This pattem exhibited a topsoil of loose, highly organic, dark gray-brown sandy loam (Munsell 7.5 YR 3/1) mixed with modem trash. This loam ranged from between 0-10 cm and contained a small amount of cultural materials. The topsoil was generally followed by a moderately compacted, brown sandy loam (Munsell 7.5 YR 3/2) containing a considerable amount of fragmented sandstone clasts beginning at depths ranging from 5-10 cm, and terminating between 15-40 cm in depth. This layer suggests that some amount of re-deposition has occuned at CA-SDI-8797. This soil stratum was followed by a moderately compacted, brown to gray-brown sandy loam (Munsell 7.5 YR 4/1) with occasional sandstone clasts beginning at depths ranging from 20-40 cm, and terminating between 40-70 cm in depth. This level contained the bulk of cultural materials recovered from CA-SDI-8797 Locus C. Finally, all units terminated between 40-90 cm within a light tan, highly compacted PJ.4-04 5-3 August 2005 Gallegos & Associates CA-SDI-8797 Locus C: DetaU Map of Indexed Area Showing 1x1 Meter Units FIGURE 5-1 Table 5-2 Culhu-al Material Recovered fi:om CA-SDI-8797 Locus C Unit Cultural Material Siurface 1 2 3 4 5 6 Total Battered Implement 1 0 1 0 0 0 0 2 Battered Implement Flake 0 1 0 0 0 1 0 2 Debitage 0 37 88 54 76 68 14 337 Bipolar Core 0 0 1 0 1 0 0 2 Flake Tool 0 0 0 0 0 1 0 1 Ground Stone 0 , 1 0 0 0 0 0 1 Mano 0 1 0 1 1 1 0 4 Pohshed Stone 0 0 0 0 1 0 0 1 SEUT 0 0 0 0 0 1 0 1 Flake from SEUT 0 0 1 8 5 2 1 17 Chestnut Cowry Shell 0 0 0 0 1 0 0 1 Bone* 0 0.8 2.45 0.1 1.75 3.25 0.05 8.4 Shell* 0 84 414.9 233.9 129.3 1437.9 53.4 2353.4 Total** 1 40 91 63 85 74 15 369 *Weight in grams **Total does not include bone or shell CA-SDI-8797 Locus C Unit 2 South Wall Profile (80 cm depth) m 10 cm 20 cm 30 cm 40 cm 50 cm 60 cm 70 cm 80 cm L KEY 1;.

A large amount of disturbance in the form of previous surface depositions was noted throughout the first 40 cm ofthe unit.

Technological identifications were determined for all analyzed flaked stone artifacts. Lithic artifacts were categorized according to toolstone material type (metavolcanic, quartzite, vein quartz, quartz crystal, and chert), technological category (tecat), and reduction stage (Appendix B). Reduction stage flake categories were defined by comparing technological attributes of replicated (experimental) artifacts from known and cataloged flaked stone tool reduction technologies to the prehistoric confrols. In tum, by comparing the technological atfributes of prehistoric artifacts (confrols) to the technological attributes of known artifacts in terms of manufacture, reduction stages were assigned to technologically diagnostic debitage. Some debitage, however, was considered technologically nondiagnostic due to the lack of technological attributes (i.e., platforms) on fragmentary pieces. Attributes evidenced on the prehistoric debitage, in conjunction with experimental analogs, were used to identify technologically diagnostic debitage that enabled flakes to be assigned to specific experimentally derived reduction stages (Flenniken 1978,1981). The remaining debitage was not ascribed to any reduction stage because of the fragmentary nature of the artifacts. Therefore, fragmentary debitage was characterized as technologically nondiagnostic, although attiibutes such as material type, and presence/absence and type of cortex were noted. 5.4.2 Analyzed Sample The artifacts included in this analysis were recovered from six excavation units. The number of unit levels analyzed are as foUows: Unit 1, four 1x1x0.1-m levels; Unit 2, eight levels; Unit 3, nine levels; Unit 4, ten levels; Unit 5, eight levels; and,.Unit 6, six levels: providing a total of 45 (1x1x0.1 m) levels producing a flaked stone assemblage sample of 337 artifacts. Each flaked stone artifact from this excavated sample was analyzed and recorded as a separate entity in an attempt to identify and isolate technological variation. Evidence to support mtentionally different technological freatment of different lithic materials within the analyzed sample was not identified. In other words. PJ. 4-04 5-16 August 2005 fl i 1 I I 1 fl I 1 I I I I fl I I I I the different lithic materials (metavolcanic, quartzite, vein quartz, quartz crystal, and chert) identified from this intta-site sample were reduced following a similar reduction sequence to manufacture similar end products. Therefore, because of the lack of infra-site technological variation, differential lithic reduction tteatment, and small sample (n=124) of technologically diagnostic debitage, all flaked stone artifacts and materials were combined for site interpretation. Furthermore, the analyzed artifacts recovered from these six excavation units were similar in technological character, and even by combining materials, the technologically diagnostic debitage (n=124, 36.8% of the total 337 flakes and flake fragments) still provided a small sample for interpretation. Therefore, all technologically diagnostic flaked stone artifacts from this analyzed sample were combined for the purpose of specific site interpretation conceming flintknapping activities. Again, only the technologically diagnostic debitage was employed for interpretation of CA-SDI-8797 flintknapping activities. Sample size requires discussion. As mentioned above, the recovered flaked stone sample from this excavated site was small (n=337); only 36.8% of the recovered debitage from this sample was technologically diagnostic. A small technologically diagnostic flaked stone sample in association with a homogeneous flaked stone sample that lacked technological variation even between different toolstone materials were additional reasons to combine technological data for interpretation of specific site flintknapping activity. 5.4.3 Technological Artifact Categories (tecats) Technological analysis of the artifacts from this CA-SDI-8797 Locus C sample identified a very interesting, and extremely limited technologically, flaked stone tool assemblage. The technological end of one reduction continuum, or the last stage of reduction, was well represented at this site. Debitage classification atfributes were divided into technological categories (tecats) that reflect technological differences in the reduction continuum and reduction stages that occuned at this site (Appendix B). Continuum is defined as a process that includes the entire life cycle of a specific flaked stone tool (including all debitage) from the selection of the raw lithic material, initial decortication, heat freatment (if applicable), reduction into the original tool, use and reuse of that tool (which may be multi-functional), rejuvenation of that tool, the deposition of that tool into PJ. 4-04 5-17 August 2005 fl I 1 1 I i I I i tt fl 1 tt I tt 1 f I fl archaeological context,-and possible reuse of that tool later in prehistoric time. Reduction stage, as employed for this analysis, is a concept designed to separate a flintknapping continuum for analytical purposes only. The reduction-oriented technological stages (processes) employed in this analysis, the flake categories, based upon replicated artifacts that conespond to those processes, and the flake attiibutes used to define those categories are all within the nodule core reduction technology that was well established in prehistoric southem Califomia. Nodule core reduction is known in the southem Califomia archaeological literature as "Cobble Core Reduction" (Gallegos et al. 2002; Gallegos et al. 2003). The term nodule was substituted for cobble because the term cobble is geologically defined as a size clast (64-256 mm) and many prehistoric core and core-based artifacts (such as some battered implements) were manufactured from boulders (>256 mm), and, to a much less extent, pebbles (4-64 mm). The term nodule was selected because a nodule can be any size and tend to be somewhat rounded to subrounded in shape. Nodule core debitage was recognized and grouped into technological categories based on the amount and location of dorsal cortex, platform attributes, dorsal arris count and direction, and flake cross/long-section shape. Debitage was classified according to two platform types identified among the flakes from nodule core reduction: natural/cortical platforms (NP) and single-faceted platforms (SFP). Multi-faceted platform (MFP) nodule core reduction debitage was not identified from this site. Flakes were further subdivided according to the location of dorsal cortex (tecats include NP-1 through NP-11 and SFP-1 through SFP-1 l)(Appendix B). The reduction-oriented technological categories of diagnostic flakes were also segregated on the basis of geological material (metavolcanic, quartzite, vein quartz, quartz crystal, and chert). Flake fragments that lacked the necessary attributes to be placed in one of these reduction-oriented tecats were classified as technologically nondiagnostic debitage with and without cortex. Only raw material type and presence or absence of cortex were recorded for these artifacts. Interpretation of the reduction sequence from this site was determined using only the technologically diagnostic debitage, wheireas discussions conceming lithic raw material types include all debitage and formed artifacts. PJ.4-04 5-18 August 2005 tt ( 1 I i Metavolcanic nodules (cobbles and boulders) were selected for size, shape, material quality, and platform location. Nodules with natiiral platforms were reduced directly by percussion in a circular manner around the natural platform. The location of dorsal cortex indicates the sequence of flake removals (Appendix B). Cores with faceted platforms were nodules that required platform preparation prior to reduction. This occuned usually when a nodule of high quality material was selected, but the nodule did not possess a naturally appropriate platform. It was therefore necessary to create a platform by percussion flaking. The desired products of nodule core reduction were flake blanks that were thick in cross-section, long and nanow in planview, and ranged in length depending upon intended use, but were most likely 5 to 12 cm in length. 5.4.4 Toolstone Materials The lithic materials employed by the prehistoric knappers at this site included a variety of metavolcanic rock, quartzite, vein quartz, quartz crystal (monocrystalline quartz), and chert, mostiy all collected from alluvial deposits. All of the identified cortex (n=38 flakes and flake fragments), with the exception of two chert flake fragments and one vein quartz flake fragment, was incipient cone cortex resulting from water fransportation ofthe lithic nodule. The exceptions were identified as primary geological cortex created naturally at the original source location. Metavolcanic materials are found as pebbles, cobbles, and boulders derived from Eocene volcanic rhyolites, andesites, and diabase of basaltic composition (Clevenger 1982). These materials have been extensively metamorphosed causing stmctural recrystallization and a rather porphyritic nature (Clevenger 1982). Metavolcanic rocks range in color from green to brown to black and require great dynamic loading forces to fracture conchoidally. Santiago Peak Metavolcanic, locally found as bedrock and redeposited float in San Diego County, known locally as "felsite," was the dominant material represented in this assemblage. Quartz is one ofthe most common lithic materials, and occurs in a wide variety of hexagonal prisms that are terminated by pyramidal shapes. It also occurs in massive, granular, concretionary, stalactitic, and cryptocrystalline habits (i.e., vein quartz). When combined with other materials, quartz or metaquartzite is refened to as quartzite, whereas a single crystal is called monocrystalline PJ. 4-04 5-19 August 2005 tt quartz. Colors range from white, red, grey, purple, yellow, brown, pink, black, green, and can be colorless as well. Quartz is ttansparent to ttanslucent with some forms occurring as opaque (i.e., quartzite). Quartz has a hardness of 7, a specific gravity of 2.65, and fractures conchoidally (Chesteraian 1995; Klein and Hurlburt 1985; Luedtke 1992; Pellant 1995). Chert is an opaque form of microcrystalline quartz composed of numerous grains that form a granular crystaUine stincture. Chert and jasper are chemically precipitated sedimentary rocks that are classed as microcrystalline but may contain sheaf-like aggregates that may include impurities such as clays, silts, carbonates, pyrites, iron, or other organic materials. Chert and jasper also may contain several forms of silica such as opal, chalcedony, or cryptocrystalline quartz. Cherts range in color from white to light gray to black. Jasper, because of the iron, is red, yellow, or brown. Green jasper is called prase or chyrsoprase. Jasper is distinguished from chert on the basis of color (Chesteraian 1995; Klein and Hurlburt 1985; Luedtke 1985; Pellant 1995). 5.4.5 Analytical Results: Technologically Diagnostic Debitage • Introduction The analyzed assemblage consists of 354 pieces of debitage manufactured from five different raw lithic materials. A total of 124 (36.8%o) artifacts were technologically diagnostic (Table 5-9), while 213 (63.2%) flake fragments were technologically nondiagnostic (Table 5-10). Of the 124 technologically diagnostic artifacts in the CA-SDI-8797 Locus C assemblage, 113 artifacts represented nodule core reduction technology, while 11 artifacts represented closely related, but potentially different flintknapping activities. • Nodule Core Reduction: NP and SFP Two nodule core platform types (NP and SFP) were represented at this site (see Table 5-9 and Appendix B)(Gallegos et al. 2002; Gallegos et al. 2003). Natiu-al platform (NP) debitage was represented by 75 flakes and single-faceted platform (SFP) debitage was represented by 38 flakes (see Table 5-9). The most frequent (n=65) natural platform debitage category was NP-11, or flakes devoid of dorsal surface cortex (see Table 5-9). This tecat is produced well after cortex removal and PJ. 4-04 5-20 August 2005 Table 5-9 CA-SDI-8797: Technologically Diagnostic Debitage Material TECAT MV Q VQ QC CH Total NP-1 1 1 0 0 0 2 NP-5 2 0 0 0 0 2 NP-6 1 0 0 0 0 1 NP-7 ' 2 0 0 0 0 2 NP-10 3 0 0 0 0 3 NP-11 63 2 0 0 • 0 65 SFP-1 4 0 0 0 0 4 SFP-5 1 0 0 0 0 1 SFP-6 2 0 0 0 0 2 SFP-7 1 0 0 0 0 1 SFP-10 5 0 0 0 0 5 SFP-11 25 0 0 0 0 25 Interior Flake 0 0 0 0 7 7 Biface Flake ' 2 0 0 0 1 3 Pressure Flake 0 0 0 0 1 1 Total 112 3 0 0 9 124 Percent 90.3% 2.4% 0.0% 0.0% 7.3% 100.0% MV = Metavolcanic Materials Q = Quartzite VQ = Vein Quartz QC = Quartz Crystal (Monocrystalline Quartz) CH = Chert Table 5-10 CA-SDI-8797: Technologically Nondiagnostic Debitage Material TECAT MV Q VQ QC CH Total With Cortex 35 0 2 0 4 41 Without Cortex 146 1 6 1 18 172 Total 181 1 8 1 22 213 Percent 85.0% 0.5% 3.8% 0.5% 10.3% 100.0% MV = Metavolcanic Materials Q = Quartzite VQ = Vem Quartz QC = Quartz Crystal (Monocrystalline Quartz) CH = Chert . flake blank production is in full force. Given the small overall size of the NP-11 flakes identified during this analysis, these flakes were most likely produced at the very end of flake core reduction just prior to the core becoming exhausted and discarded, and/or laterally cycled into another fiinctional tool such as a battered implement. The remaining 10 other natural platform flakes were produced throughout the reduction cycle, and with the exception of the two NP-1 flakes, all exhibited minimal dorsal cortex (see Table 5-9). The same technological reduction pattem was repeated, almost identically, with the single-faceted platform debitage-(see Table 5-9 to compare NP tecats to SFP tecats)(see Appendix B). The most commonly occurring (n=25) single-faceted platform debitage category was SFP-11 (see Table 5-9). As mentioned above, multi-faceted platform nodule core debitage was not identified in this assemblage. Most ofthe recovered debitage was too small for flake blanks, or was broken, or too thick, and was therefore discarded. For the most part, the CA-SDI-8797 Locus C nodule core debitage is small in overall size (< 3 cm long) and slightly curved in long-section, both attiibutes would indicate production from small cores or cores with short working faces. This debitage produced from flake cores was placed into two general technique categories: rejected flake blanks or working face preparation flakes. Rejected flake blanks may be the appropriate length (> 5 cm), but were rejected because they were too thick, too nanow, covered with too much cortex, too many stacked step fractures on the dorsal surface, broken by sheared cones (common at this site), etc. Working face preparation flakes are generally too small (< 3 cm), ttiangular in cross-section, and thick for use as they were most frequently produced as platform over-hang removal flakes, and/or to sfraighten the arrises on the face ofthe core. Useable flake blanks may have been ttansported from the site for use elsewhere. • Interior Flake Seven early interior flakes with single-faceted platforms, all manufactured from chert, were identified among the analyzed artifacts from this site (see Table 5-9). The pattem of single-faceted platform preparation common in the other lithic materials continues in tiiis material, suggesting that PJ. 4-04 5-23 August 2005 even though this is a small sample, chert was tteated technologically the same as the other lithic materials from this assemblage. These flakes were small (rarely over one cm in length), thick relative to overall size, irregulariy shaped, exhibited sheared cones, and dorsal and venfral flake scars were covered with pronounced compression rings. These flakes were not adequate for production of small tools, such as projectile points or small flake tools. These chert eariy interior flakes with single-faceted platforms were most likely produced during the later stages of chert nodule core reduction, not the early stages of nascent biface manufacture. • Biface Flake Three early stage bifacial thinning flakes (two of a fined-grained, green metavolcanic material and one of a chert) were identified, with reservations, during this analysis (see Table 5-9). These flakes, while possessing most of the technological atiributes afforded to bifacial thinning flakes, had single- faceted platforms and cortex on the dorsal surface at the distal end of the flake. In large samples of bifacial thinning flakes, several flakes may have single-faceted, abraded platforms and cortex, but a small sample of three, all with single-faceted platforms and cortex, suggests these flakes were most likely "adze flakes." ' • Pressure Flake One very small chert flake was identified as a pressure bifacial thinning flake (see Table 5-9). This sample of one flake most likely is not a pressure flake, but rather a small flake with very similar pressure flake technological attributes that were created fortuitously. • Adze Flake Seventeen flakes from CA-SDI-8797 Locus C were identified as adze (SEUT) resharpening flakes, which possess many technological attributes in common with bifacial thiiming flakes (see Table 5- 9). Adzes, effective woodworking tools (Gallegos et al. 2002; Gallegos et al. 2003), are typically "...circular or semi-circular in outiine form and have a low profile for the frontal view with the PJ. 4-04 5-24 August 2005 • contiguous planer use-wear located near the working element" (Schroth and Fleimiken 1997). Functioning adzes most likely were ttansported from site to site for use as woodworking tools. A total of 17 adze resharpening flakes were identified during this analysis. This tecat typically has a single-faceted platform (some have cortical, as well as multi-faceted platforms), multiple series groups of stacked step fractures on the proximal end ofthe dorsal surface, multiple linear flake scars and anises on the dorsal surface, more or less parallel side margins, slightly curved in long-section, feather termination at the distal end, and most importantiy, have excessive polish/abrasion (from contact with wood surfaces) with linear striations that are pattemed perpendicular (or oblique) to the flake platform as well as the margin ofthe adze from which it was produced. Therefore, adze flake debitage indicates adze resharpening, not manufacture. 5.4.6 Analytical Results: Technologically Nondiagnostic Debitage • With Cortex Forty-one (35 metavolcanic, 2 vein quartz, and 4 chert) technologically nondiagnostic flake fragments that exhibited incipient cone cortex were examined for this analysis (see Table 5-10). Most of these flake fragments were small, angular, and appeared to be byproducts of nodule core reduction. • Without Cortex One hundred seventy-two (146 metavolcanic, 1 quartzite, 6 vein quartz, 1 quartz crystal, and 18 chert) technologically nondiagnostic, cortex-free flake fragments were also examined for this analysis (see Table 5-10). As with the cortical flake fragments, most of these pieces of debitage were small, angular, and also appeared to be by-products of nodule core reduction. However, several fine-grained, green metavolcanic flake fragments most likely were broken adze resharpening flakes. PJ. 4-04 5-25 August 2005 5.4.7 Technological and Functional Summary • Nodule Core Reduction Nodule core reduction technology is the most common core technology identified in this CA-SDI- 8797 Locus C assemblage (Gallegos et al. 2002; Gallegos et al. 2003). Products of nodule core reduction are also the most abundant as measured by percent (77.9%) of technologically diagnostic flakes. This simple and expedient technology may have been so commonly used because it provided a simple and relatively effortless way to produce useful flakes, and flake blanks intended for immediate use or further reduction. Because of the local (San Diego County) abundance of metavolcanic materials, there was often little need for more material-efficient, and consequenfly more time-consuming technologies. Debitage produced from nodule core reduction was classified according to the pattem of dorsal cortex present (if any), dorsal arris pattems, and platform attributes. Dorsal cortex attributes provide clues conceming two processes: stage of reduction and patteming of flake removals. The amount of cortex will decrease through the reduction sequence. Flakes with 100%o dorsal cortex (NP/SFP/MFP-1 s), therefore, usually result from earlier portions of the sequence while flakes with no dorsal cortex (NP/SFP/MFP- lis) result from the latter portions of the sequence. The abundance of flakes that lack dorsal cortex exist because, once cortex is removed from a nodule early in the reduction sequence, all subsequent flakes will lack dorsal cortex. The positioning of dorsal cortex results from the patteming of flake removals (clockwise, counter- clockwise, or unpattemed in relation to the platform). The analysis of this assemblage did not reveal meaningful pattems regarding the sequence of flake removals mostly because ofthe small sample size. Most likely at this site, cores were not consistently reduced in, for example, a clockwise sequence, but rather reduced in the maimer in which the maximum amount of flakes blanks could be produced considering the shape of a selected nodule. Another aspect of variability seen in the nodule core reduction debitage assemblages relates to platform characteristics. This variability also appears to result purely from technological PJ. 4-04 5-26 August 2005 considerations rather than, for instance, a "mental template" to which might be attached some chronological or ethnic significance. Three examples of platforms are frequentiy found (unprepared/natiiral/cortical jjNP], single-faceted [SFP], and multi-faceted [MFP]), and they vary, in part, according to the amount of shaping required to obtain a suitable platform configuration for successful flake removals (a uniform platform surface and adequate platform-to-core face angle). Some nodules did not require shaping (natural platforms) to obtain a proper platform configuration; others required more (multi-faceted platforms) or less (single-faceted platforms) shaping. It is expected that these different platform types could be produced within a single reduction sequence as a result of adjustments made in response to the changing shape of the core as it was reduced. One source of inter-site variation may relate to the portion of the nodule core reduction sequence conducted at a site. It appears that cores were not always entirely reduced at a single location, but rather initial shaping may have been performed at one site and subsequent core reduction was performed at another. This is indicated at some sites wherein few early stage flakes were found, but later stage flakes were common, such as CA-SDI-8797. Altematively, this pattem could be explained as a result of sampling bias resulting from incomplete or non-representative artifact collections. 5.4.8 Conclusions With the above discussion serving as an overview of nodule core reduction, the analyzed assemblage from CA-SDI-8797 provided an example of a site wherein only the last stages of nodule core reduction occuned. Ofthe 113 nodule core reduction flakes identified in this collection, 98 (86.7%) were NP-10, NP-11, SFP-10, and SFP-11 (see Table 5-9). Therefore, the primary flintknapping activity that occuned at this site was associated with nodule core reduction, and the predominant aspect of nodule core reduction was the production of a few very late stage flake blanks, most likely for unmodified flake tools. In other words, selection of nodule core toolstone, nodule core platform preparation, nodule core decortication and manufacture, and extensive nodule core reduction did not occur at this site. Only late stage flake blanks were produced at this location. The few chert interior flakes also support this technological observatioii. Based upon the analyzed assemblage from CA- SDI-8797, flintimapping activities were limited to minimal nodule core flake blank production. PJ.4-04 5-27 August 2005 minor adze resharpening, and minor mano/metate resharpening. Therefore, site activities involving limited use of unmodified flake tools, woodworking adzes, and grinding of plant/animal resources on metates were identified. It should be noted that an additional interpretation of the CA-SDI-8797 flaked stone assemblage is that all of the debitage, with the exception of 2 battered implement flakes and 2 bipolar cores, were related solely to adze maintenance. Potentially, of the 337 flakes and flake fragments, all but the 17 adze production flakes were adze preparation, reshaping, and resharpening debitage removed after or before the adze was used, and acquired the distinctive edge polish associated with adze flakes. In other words, the NP flakes, SFP flakes, interior flakes, biface flakes, and pressure flake, were produced during knapping of adzes. Nodule cores and adzes are the same morphological artifact class, and were produced by the same reduction sequence, but served very different functions. Furthermore, nodule cores and adzes may have been within the same reduction frajectory in that once the nodule core became "exhausted" for flake blank production, they may have been laterally cycled, with minimal alteration, into adzes. 5.5 FORMED ARTIFACT ANALYSIS (by Tracy Stropes and Jeff FlennUcen) 5.5.1 Cores Two small, exhausted chert bipolar cores were identified in this assemblage. Both artifacts were probably discarded because of their small size and crashed nature rendering them useless for fiirther flake production or use as some other fimctional tool. The presence of a bipolar technology suggests quality stone may have been at a premium at this location. 5.5.2 Utilized Flake Tool Utilized flakes are flakes with a minimal amount or no shaping, with modification (if any) generally restricted to the working edge often resulting from naturally occurring use-wear. These tools are frequently used for a short period oftime, and then discarded. A single laterally utilized flake was identified in the present collection. Laterally utilized flake tools exhibit use or modification along a single lateral margin of the flake from which the tools were produced. The present specimen PJ. 4-04 5-28 August 2005 tt tt I I I maintains a relatively sfraight edge. The angle of the working faces of the specimen is relatively low (less than 45 degrees). The specimen also exhibits slight modification to the working edge and is unifacial in form. The edges appear to have been retouched in order to facilitate a relatively sfraight cutting edge. It is likely that this flake tool was used in a scraping motion for various purposes, including the working of opposing curved surfaces (such as vegetable products), animal materials (such as animal hides), and/or other softer stone. The specimen is small (<4cm) in length, indicatmg more controlled/precise working activities. 5,5.3 Steep-Edged Unifacial Tools (SEUTs) Southem Califomia archaeology has recovered numerous amorphous lumps of metavolcanic stone that possess steep, unifacial edges for years. These objects have long been recognized by archaeologists as artifacts. However, these steep-edged unifacial tools, or SEUTs, have been subjected to numerous morphological and functional categories (i.e., horse hoof scraper, scraper plane, flake scraper, biscuit scraper, various core types, etc.). Schroth's (1997) analysis of flaked stone tools from CA-SDI-11424 is by far the best effort to sort these artifacts into techno-fimctional categories. The category of adze, or woodworking tool, defines these tools. A single SEUT, and 17 flakes from SEUTs (adzes) were recovered from CA-SDI-8797 Locus C. SEUTs are plano-convex in cross-section, have steep sides, are almost circular in planview, are heavy, and most importantly, have strong acute cutting edges. These tools are ideal woodworking tools because they are often sharp, weighted, and durable. Brian Hayden's (1979) ethnographic study in Austtalia, Palaeolithic Reflections, describes the manufacture and use of SEUTs by Australia's indigenous people in great detail. Given that the environments of Austtalia and southern Califomia are very similar, and that tools for woodworking were essential aspects ofthe prehistoric tool kit, southem Califomia SEUTs were most likely used in a similar manner. This fimctional interpretation is supported by the fact tiiat these two tool categories are the same in terms of manufacture, material quality, size, shape, wear-pattems, and overall variation. Additionally, experimentation described by Schroth (1997:8-62) supports the use of SEUTs as adzes. PJ. 4-04 5-29 August 2005 I fl Morphological variation within the SEUT category is, perhaps, the main reason for the numerous « scraper, plane, etc., categories. However, this variation in size and weight was a technological ™ consideration for the various tasks required of these tools. With basically the same atiributes, except size and weight, these tools fimctioned as adzes, with different sizes and weights being essential for different tasks at hand. The most critical attribute, in addition to size and weight, was the acute sharp cutting edge. When this edge became dulled during woodworking, the tool was resharpened or rejuvenated by removing flakes from the steep face while employing the piano-surface as a platform. These flakes are diagnostic, and were identified at CA-SDI-8797. fl fl tt I fl I fl I tt tt 1 I tt I I fl The single SEUT specimen, and 17 flakes from SEUTs identified in this analysis are very similar to other SEUT/adze specimens from sites such as CA-SDI-12814 (Gallegos et al. 2001), and CA-SDI- 5581 (Gallegos and Sfropes 1999). However, the specimens from CA-SDI-8797 are considerably smaller than the average SEUT/adze specimen. The present size of the specimens may be a reflection of use-life termination, and not the ideal tool size and form. The specimen exhibits primarily unifacial use-wear, with a minimal amount of grinding visible on the venfral surface. The small size of these tools may indicate more confroUed tool functions such as specified scraping tasks ranging from fiber processing to the shaping of bone or wood artifacts. 5.5.4 Battered Implements Two battered implements and two metavolcanic battered implement flakes were examined during this analysis. These artifacts support a ground stone technology in association with the flaked stone technology at CA-SDI-8797. Prehistoric flaked stone assemblages from southem Califomia, Utah, Nevada, and the American Southwest contain a common artifact identified by archaeologists by a variety of names including chopper, hammerstone, pounder, muller, milling stone, flaked hammerstone, handstone, battered hammerstone, masher, basher, utilized core, scraper planes, pecking stone, fist ax, and hand ax (Dodd 1979; Wallace 1978). Many of these artifacts are employed as archaeological identifiers of specific prehistoric cultures (Wallace 1954; Kowta 1969). Others are simply weighed, measured, and described generally as plant and animal resource processing tools. PJ. 4-04 5-30 August 2005 I fl fl fl I fl I fl fl I I I fl fl fl II 11 II Dodd (1979) and others (Ambler 1985; Geib 1986), however, have devoted considerable time and energy to the identification and function of a rather unsophisticated but highly specialized and important prehistoric tool class, battered hammerstones. Battered hammerstones are separated from the otiier artifact classes on the basis of pock marks located on one or more intentionally prepared areas on a single tool that are a result of repeated pounding against another hard object. These implements are most frequently produced from conchoidal fractining, subrounded to subangular, spherical to discoidal, cobble-sized, quartzite, chert, metavolcanic, and volcanic nodular alluvial materials. The manufacturing process includes the selection of a check-free rock (or most likely at CA-SDI- 8797, an exhausted NP flake core, SFP flake core, or adze) of the appropriate, material and size. After material selection, a unifacial or bifacial sinuous edge (or platform edge on a flake core) was produced by direct free hand percussion. The sinuous edge may have been situated on the side of the nodule, end ofthe nodule, or completely sunounding tiie nodule. The debitage produced as a result of edge manufactiire is characteristic of initial nodule reduction, but is not well-pattemed because ofthe variation in size, shape, and quality of the selected cobble. Because a sinuous edge was the "intended end product," general debitage characteristics may include cortex (in varying amounts) on the dorsal surfaces and platforms, few dorsal surface arrises, hinge terminations, thick flake cross-sections, angular flake planviews, single-faceted platforms, and more rarely, multi- faceted platforms (interior flakes). Once the sinuous edges were produced to satisfaction, the linear-edged hammerstone was ready for use. The use of these hammerstones produced battered edges: the longer the use, the more intense the battering. At some time during tiie use process, the battered hammerstone required resharpening. Resharpening included the removal of flakes by direct free hand percussion along the sinuous margin until the battered edge surfaces were partially or totally eliminated. A portion of the debitage produced during the resharpening process is very distinctive in that the battered edge that was once on the hammerstone is present on the proximal end of the dorsal surface of the resharpening flake (battered implement flakes). However, flakes that do not exhibit battering on their dorsal surface were also produced, and are impossible to assign to the resharpening process. PJ.4-04 5-31 August 2005 II II II Once again, the hammerstone was ready for use. After numerous use/resharpening events, battered tools were discarded into archaeological context. These discarded battered implements occur as exhausted, well-wom, intensely battered tools, or as resharpened, sharp-edge, small hammerstones with isolated areas of intense battering on one or more previously used margins. The latter were discarded because they were too small and lack the specific gravity to function efficientiy. Experimental (Flenniken et al. 1993) and ethnographic data (Bartlett 1933; Hayden and Nelson 1981; HUl 1982; Hough 1897; Lange 1959; Michelsen 1967; Simpson 1952) document ground stone tools, mainly manos and metates, were manufactured, sharpened, and resharpened with battered implements (Flenniken et al. 1993). The sample of two battered implement flakes suggest manos and/or metates may have been resharpened at CA-SDI-8797. 5.6 GROUND LITHIC ARTIFACTS 5.6.1 Introduction All ground stone materials recovered from CA-SDI-8797 Locus C were selected for analysis and interpretation. Ground stone implements may include a wide range of objects used to, or created by the processes of abrasion, impaction, or polishing (Adams 2002). Often, ground stone tools are associated with the processing/milling of seeds, nuts (i.e., acoms, walnuts, holly leaf cherry), and tiie processing of small mammals. In addition, ethnographic evidence indicates that bone, clay, and pigments may have also been processed using the same tools (Gayton 1929; Kroeber 1925; Spier 1978). Implements of this type may be identified by the pattem of wear developed through milling stone against stone. This process often results in a smooth and/or polished surface, depending on the substance ground and the lithic material type. Often these surfaces are pecked or resharpened when ground too smooth. These implements are sometimes shaped into a desired form through pecking, grinding, or flaking. Thus, tool identification is based on the presence of ground or smooth surfaces, pecked or resharpened surfaces, and evidence of shaping ofthe tool form. The tools were separated into three groups: manos/metates, unidentifiable ground stone fragments, and battered implements. Unidentifiable ground stone is defined herein as a fragment of lithic material with a minimum of a single ground surface, but with no technologically identifiable characteristics to indicate tool form. •PJ. 4-04 5-32 August 2005 5.6.2 Manos Four manos (1 complete, 3 fragmentary) were recovered during excavations at CA-SDI-8797 Locus C. Three ofthe manos recovered are fragments of volcanic nodules, and one is a granitic specimen. Bifacial use-wear predominated the coUection. Only one of the manos recovered shows evidence of shaping, reflecting a dominant trend toward the expedient use of cobbles. All of the manos are natural cobbles from locally available resources. There is end-battering present on one of the specimens and two exhibit pecked grinding surfaces. The end-battering visible on the specimens may indicate that the manos were also used as hammers to sharpen metate grinding surfaces when they became too slick to grind. The overall curvature of each mano face is slight indicating that the opposing milling surface that the manos were ground against (i.e., metate, milling slick) was shallow in form. In addition, the grinding patterns evident on the faces of each mano indicate that the majority of manos are basin manos used primarily in a reciprocal sfroke manner in concert with shallow basin metates (Adams 2002). All ofthe manos collected were thermally damaged to varied degrees. It is possible however, that some ofthe manos were recycled for use in rock hearths or earth ovens. In general, the ratio of manos to metates at a site where milling technology is present is much greater. It has been suggested that the reason for this is that manos wear out much faster than metates (Wright 1993), and thus more manos are produced as needed. The relatively small milling assemblage recovered from CA-SDI-8797 Locus C suggests that the inhabitants ofthe site had only a minimal dependence on food packages that required milling for processing (i.e., grass seeds). It is evident that the diet ofthe inhabitants of CA-SDI-8797 was primarily derived from plant foods tiiat did not require milling technology for processing or consumption, or that plant foods were only a small part ofthe diet. 5.6.3 Ground Stone Fragment One ground stone fragment was identified in the present collection. In general, a ground stone fragment is defined as a piece of ground stone implement that has some grinding, but lacks any defining atiributes that would facilitate tool identification. The smaU fragment recovered from CA- SDI-8797 Locus C is granitic and thermally damaged. PJ.4-04 5-33 August 2005 5.7 INVERTEBRATE FAUNAL ANALYSIS (by Tracy Sfropes) 5.7.1 Introduction Invertebrate remains recovered from the excavation of six units at CA-SDI-8797 Locus C totaled 2,353.4 g. All shell recovered from the site was identified to species, order, and class. A total of 12 species, 4 orders, and 3 classes of invertebrate remains were identified within the six analyzed units. These shellfish species were representative of three marine environments: bay/lagoon/estuary; rocky shore/outer coast; and sandy beach. 5.7.2 Methods Each shell was weighed and examined to identify genus and species. All shell was speciated in order to determine habitat exploitation pattems and to obtain paleo-environmental data. 5.7.3 Results The 2,353.4 g of invertebrate remains recovered by unit (from highest to lowest weight) are as follows: Unit 5 (1,437.9 g). Unit 2 (414.9 g), Unit 3 (233.9 g). Unit 4 (129.3 g), Unit 1 (84.0 g) and Unit 6 (53.4 g). Table 5-11 illustrates that the majority of shell across the site was recovered from the 0-60-cm level. Ofthe 2,353.4 g of shell recovered, 1,655.9 g were identifiable to species. The remaining 697.5 g were determined to be too fragmentary or weathered for proper identification. Table 5-12 lists the species identified and their habitats. The majority of invertebrate remains were gathered from bay/lagoon/estuary environments (95.2%), followed by rocky shore/outer coast environments (4.6%)), and minimally from sandy beach environments (0.2%o)(Figure 5-3). This data identifies an exploitation focus by the inhabitants of CA-SDI-8797 on bay/lagoon/estuary environments. Table 5-12 illusttates that the majority of the identifiable shellfish species recovered from the six units were Chione sp. (56.5%), Argopecten sp. (29.6%), Ostrea lurida (4.5%), Polinices sp.

The remaining.species from the site contributed to less than one percent of the total specimens. In summary, the invertebrate shell data identifies that the inhabitants of CA-SDI-8797 primarily exploited bay/lagoon/estuary habitats for shellfish. However, there is some evidence of exploitation of rocky shore/outer coast habitats as well. It is likely that this exploitation pattem represents a focus on primarily a single environment with opportunistic gathering near rocky shore/outer coast locations. The radiocarbon dates support this exploitation pattem. Given the results of shellfish analysis for CA-SDI-8797, the inhabitants likely exploited the nearest lagoon habitat (Agua Hedionda Lagoon), and occasionally visited other nearby shoreline areas. 5.8 VERTEBRATE FAUNAL ANALYSIS (by Patricia Mitchell) 5.8.1 Introduction The bird, mammal, and fish bone collection from site CA-SDI-8797 Locus C consists of 73 fragments with a combined weight of 8.4 g. Two of the fragments (1.3 g) were determined to be intrasive to the prehistoric site. Both of these bone fragments exhibit signs of intrasiveness such as oily texture, or fragile, whole elements. The oily texture suggests the presence of collagen in the bone, and therefore, the bones are most likely the result of a recent, natural death and were not included in the following data tabulations. The remaining 71 (7.1 g) bone fragments were recovered from the 0-90-cm levels of six excavation units. All bone fragments were identified to class, order, family, or when possible to genus and species. One animal species, Sylvilagus audubonii (desert cottontail rabbit), was identified. The remaining bone fragments lacked the morphological features that would have allowed them to be identified to a taxonomic category greater than their class. Other categories used to identify these fragments include small bird, teleostei, marine mammal, small mammal, medium mammal, and large mammal. Evidence of buming was present on a portion of the collection and has allowed for some interpretation of the preparation of the meat portion ofthe inhabitants' diet at site CA-SDI-8797. PJ. 4-04 5-38 August 2005 Figure 5-4 CA-SDI-8797 Comparison of Major Species by Deptii 250 • Argopecten • Chione • Donax gouldu • Ostrea lunda fl 5.8.2 Methods Each bone was examined to determine: • element • right or left side • highest taxonomic category • evidence of buming, and if so, what degree of oxidation • evidence of butchering, and if so, what method of butchering Comparative skeletal collections used in the identification process included those from Scripps Institute of Oceanography, as well as from private collections and a photographic database. Bone atiases (Lawrence 1951; Nickel et al. 1986; Olsen 1985; Sandefiir 1977; Schmid 1972) supplemented the analysis. Categories used in this analysis include: Bumed: Bone elements or fragments that show color change from exposure to heat or fire (oxidation). Colors may include: • brown = exposure to heat,, but little or no exposure to open flames. • black = direct exposure to open flames (i.e., roasting or discard in a fire). • blue/white (calcined) = direct exposure to a fire hotter than 800° Celsius (Ubelaker 1978). This may represent bone that was severely bumed during preparation, in which case, if flesh was present on the bone during exposure to the fire the bone would exhibit signs of warping and shrinking (Ubelaker 1978). Calcined bone may also be the resuh of having been discarded in a fire hearth (Wing and Brown 1979). Unbumed: No evidence of buming or oxidation. Butchered: Bone with evidence of processing by slicing or chopping actions. Bird: Bones that have thin walls in cross-section, are hollow, and light in weight. These are often distinguishable from mammal bone because they contain large cavities tiiat would have been filled with air in life. Small Mammal: All nondiagnostic vertebrate fragments, whose sizes are between a mouse and a jackrabbit. PJ.4-04 5-40 August 2005 Medium Mammal: All nondiagnostic vertebrate fragments, whose sizes are larger than a jackrabbit, but smaller than a deer. Large Mammal: All nondiagnostic vertebrate fragments, whose sizes are deer-size and larger. Marine Mammal: Sea mammals' bones are often distinguished from other medium or large-sized terrestrial mammals by the spongy texture. Teleostei: Funnel-shaped vertebrae with/without the spinous process attached, and other skeletal elements considered as bony fish. The quantification of faunal material can be studied using several methods. The methods used in individual studies are usually determined by sample size and type of site being investigated. Two methods were used in this study: the number of identified specimens per taxon (NISP), which represents the total number of specimens within a category; and the minimum number of individuals (MNI), which represents the minimum number of individuals within a genus and species category. 5.8.3 Results The animal remains recovered from the six excavation units consisted of 71 (7.1 g) bone elements from the 0-90-cm levels of CA-SDI-8797 Locus C (Tables 5-13 and 5-14). One Sylvilagus audubonii (desert cottontail rabbit) bone was identified from the collection of 71 bone elements. The remaining 70 pieces of bone lacked the morphological features that would have allowed them to be identified to the genus and species level, and were therefore identified as small bird, teleostei, marine mammal, small mammal, medium mammal, or large mammal. Horizontal distribution of NISP counts presented in Table 5-13 shows that the majority of bone elements were recovered from Unit 5 (35.2%), followed by Unit 4 (32.4%), and Unit 2 (23.9%). The remaining three units contributed less than 5 percent each. Table 5-14 presents the resuhs ofthe vertical distribution of NISP counts for the six units. There is a steady increase of vertebrate remains recovered from the surface to the 20-cm levels (NISP=2 to NISP==8). No culturally-deposited vertebrate remains were recovered from the 20-30-cm level. The NISP counts begin to decline from the 30-40-cm level (NISP=6) before increasing again in the next PJ. 4-04 5-41 August 2005 Table 5-13 CA-SDI-8797: NISP Distiibution of Vertebrate Remains by Unit Unit Specimen 1 2 3 4 5 6 Total Percent Sylvilagus audubonii 0 1 0 0 0 . 0 1 1.4% Large Mammal 0 1 0 0 2 0 3 4.2% Marine Mammal 0 0 0 0 1 0 1 1.4% Medium Mammal 0 0 0 0 1 0 1 1.4% Small Mammal 3 14 2 22' 19 1 61 85.9% Small Bird 0 1 0 0 1 0 2 2.8% Teleostei 0 0 0 1 1 0 2 2.8% Total 3 17 2 23 25 1 71 100.0% Percent 4.2% 23.9% 2.8% 32.4% 35.2% 1.4% 100.0% Table 5-14 CA-SDI-8797: NISP Distribution of Vertebrate Remains by Depth Specimen 0-10 cm 10-20 cm 30-40 cm 40-50 cm 50-60 cm 60-70 cm 70-80 cm 80-90 cm Total Percent Sylvilagus audubonii 0 0 1 0 0 0 0 0 1 1.4% Large Mammal 0 0 0 0 3 . 0 0 0 3 4.2% Marine Mammal 0 0 0 0 1 0 0 0 1 1.4% Medium Mammal 0 1 0 0 0 0 0 0 1 1.4% Small Mammal 1 7 5 10 23 4 10 1 61 85.9% Small Bfrd 0 0 , 0 1 1 0 0 0 2 2.8% Teleostei 1 0 0 0 1 0 0 0 2 2.8% Total 2 8 6 11 29 4 10 1 71 100.0% Percent 2.8% 11.3% 8.5% 15.5% 40.8% 5.6% 14.1% -1.4% 100.0% two 10-cm levels (NISP=11 to NISP=29). The bone counts in the 60-70-cm level drops off dramatically (NISP=4), and increases once more in the 70-80-cm level (NISP=10) before terminating at the 80-90-cm level with a NISP of one. The majority of bone elements (56.3% combined) were recovered from the 40-60-cm levels. Throughout the site, the highest bone element count was identified as small-sized mammals, and included Sylvilagus audubonii (MNI=1), and small mammal (87.3% combined). The remaining animal resources contributed little to the meat portion of the inhabitants' diet: large mammal resources were 4.2%; avian and fish resources were 2.8%) each; and medium mammal and marine mammal resources were less than 1.5%) each. As seen in Table 5-15, evidence of buming was present on the majority.of the coUection (63.4%)). Ofthe 45 bones bumed, 95.6% (n=43) were bumed brown in color, indicating exposure to heat, but not to a direct flame. This suggests that these animals were likely cooked in some type of container (i.e., pottery, stone, basketiy). Dracker (1937) noted that the bones of small mammals, and the meat were pulverized, and that heated stones were used in baskets for cooking (stone boiling) by the Luiseiio Native Americans. Animal species or categories bumed brown in color included: Sylvilagus audubonii, small bird, teleostei, small mammal, medium mammal, and large mammal. None ofthe bones were bumed black in color. The specimens that were calcined (4.4%, n=2 ofthe bumed elements) were exposed to a direct flame at extremely high temperatures (greater than 800° Celsius). None ofthe calcined bones exhibited signs of shrinking or warping. These are atttibutes that indicate the presence of soft tissue on the bone at the time of exposure to an open flame. It is likely that the calcined specimens were the resuh of being discarded in a fire hearth. Animal species or categories calcined include small mammal. 5.8.4 Butchered Bone No evidence of butchering was observed on the vertebrate remains recovered from CA-SDI-8797 Locus C.

Desert cottontail rabbits can be found in open plains, foothills, low valleys, and coastal areas, and are easily caught with a rabbit stick or bow and anow (Christenson 1986). Dracker (1937) also noted that rabbits were hunted in communal drives and driven into nets. They are most active in early moming, late aftemoon, and at night. Their diet consists of green vegetation and fmit (Russo and Oldhausen 1987). The desert cottontail was probably hunted for food, as well as for its peh (Schroth and Gallegos 1991). 5.9 RADIOCARBON DATING ANALYSIS 5.9.1 Sample Results Four shell samples were submitted to Beta Analytic, Inc., for accelerated mass specttometry (AMS) analysis (Table 5-16 and Appendix E). Specimen CA-SDI-8979-86 was collected from the 70-80- cm level of Unit 4 and is a Cypraea spadicea Swainson (Chestaut Cowry) shell fragment. Cowries are considered to be more often associated with Early Period sites, therefore, this shell was selected to determine the age of the basal level ofthe deposit. The sample provided a date (at two-sigma range) of AD 1650 to AD 1870 (Cal BP 300 to 80). This date identifies occupation within the Late Period. Specimen CA-SDI-8797-99 was coUected from the 20-30-cm level of Unit 5 and is a Polinices sp. specimen. Polinices sp. shell is often associated with Early Period sites, therefore, this specimen was selected to determine the age of the upper portions of the deposit. In addition, a Polinices sp. specimen was sampled from CA-SDI-8303 (considered primarily a Late Period site), and from CA- SDI-8694 for comparison. The sample provided a date (at two-sigma range) of BC 3320 to BC 2910 (Cal BP 5270 to 4860).

Donax sp. shell is often associated with Late Period sites, therefore, this specimen was selected to determine if there is Early/Late Period component mixing within the deposit. The sample provided a date (at two-sigma range) of BC 1270 to BC 990 (Cal BP 3220 to 2940). This date identifies occupation for CA-SDI-8797 witiiin the later part of the Eariy Period. The last sample (specimen CA-SDI-8797-106) was selected to, confirm or reject the early date received on the Donax sp. sample specimen CA-SDI-8797-110. Donax sp. shell, as mentioned previously, usually dates to the Late Period (circa 1,500 years ago to present). The sample (specimen CA-SDI-8797-106) was also selected from the 40-50-cm level of Unit 5. This sample produced a date (at two-sigma range) of BC 1400 to 1160 (Cal BP 3360 to 3110) and confirmed the use of Donax sp. shell as a food resource circa 3,000 years ago within the later part ofthe Eariy Period. It should be noted that the majority of shell (95.2%)) recovered from CA-SDI-8797 Locus C was from bay/lagoon/estuary environments, 4.6% from rocky shore/outer coast environments, and 0.2% (Donax gouldii) from sandy beach environments. 5.10 SITE SUMMARY The Indexing and Preservation Study for CA-SDI-8797 Locus C included field excavation of six 1x1 -m units, artifact cataloguing, data analysis, and special sttidies. The purpose ofthe Indexing and Preservation Study was to provide an index sample representing the deposit being capped and preserved. The fieldwork resulted in the collection of 337 debitage, 2 cores, 1 flake tool, 1 steep- edged unifacial tool (SEUT), 17 flakes from SEUTs, 2 battered implements, 4 manos, 1 ground stone fragment, and 1 polished stone. Faunal material includes 8.4 g of bone and 2,353.4 g of shell. Disturbance from constraction, agricultural activities, and bioturbation was noted in all units. The range of artifacts at CA-SDI-8797 indicates a habitation site occupied at a minimum during the Middle to Late Holocene. Flake production from local cobbles, suggests flake tool use. Therefore, the primary flintknapping activity that occiuxed at this site was associated with nodule core reduction, and the predominant aspect of nodule core reduction was the production of a few very late PJ. 4-04 5-48 . August 2005 stage flake blanks, most likely for unmodified flake tools. In other words, selection of nodule core toolstone, nodule core platform preparation, nodule core decortication and manufacture, and extensive nodule core reduction did not occur at this site. Only late stage flake blanks were produced at this location. The few chert interior flakes recovered support this technological observation. Hunting activities may have occuned near this site as indicated by the faunal assemblage. The presence of five ground stone tools and two battered implements represents preparation of plant foods through pounding and/or grinding. The presence of shellfish remains and the range of small to large mammal bone demonsttates the range of foods collected, hunted, and processed. A nanow range of hunting and collecting activities characterizes the site. Analysis of the 2,353.4 g of shell recovered from CA-SDI-8797 Locus C identifies that the majority of the identifiable shellfish species were likely collected from Agua Hedionda Lagoon, and that the site's inhabitants occasionally visited other shoreline areas. The radiocarbon dates identify occupation of the site primarily during the Early Period (Middle Holocence) circa 3320 BC to 990 BC (see Section 5.9 discussion). However, a Late Period occupation component was identified by the radiocarbon date range from 1650 AD to 1870 AD (Cal BP 300 to 80). As demonsttated by the radiocarbon dates, site CA-SDI-8797 is a multi-component site with a dominant Early Period component and minimal evidence of a Late Period component. PJ. 4-04 5-49 August 2005 SECTION 6 SITE DISCUSSIONS By Tracy Stropes, Monica Guenero, and Dennis Gallegos 6.1 RESEARCH QUESTIONS Research questions were addressed to provide a theoretical framework for the data recovery program. The following section addresses the research questions conceming chronology, lithic technology, subsistence sfrategy, site type and settlement pattem, and trade and travel discussed previously in Section 2. Each site will be discussed separately under the research topic posed. 6.2 CHRONOLOGY • What was the period of use and/or occupation? 6.2.1 CA-SDI-8303 Radiocarbon analysis as a result of this study, places primary site occupation during the Late Period, circa 100 to 980 years ago (see Section 3.13). In addition, minor evidence of an Early Period occupation component is supported by a radiocarbon date of 6,500 to 6,730 years ago (Beta 197208). The radiocarbon dates are supported by the presence of a high amount of Donax sp. shell (71.6%)), a sandy beach shellfish species exploited primarily during the Late Period, and a low amount, of bay/lagoon/estuary shellfish species (28.3%)) that were heavily exploited during the Early Period. Previous work and the present study produced 11 radiocarbon dates from CA-SDI-8303 identifying primary site occupation during the Late Period (Table 6-1 and Figure 6-1). Late Period occupation is additionally supported by the presence of small anow points, ceramics. Obsidian Butte obsidian, and glass frade beads. The Early Period occupation is additionally supported by the presence of one piece of obsidian sourced to the Coso Volcanic Fields located in Kem County, Califomia.

capture as summer (May to October). According to the otolith analysis, site CA-SDI-8303 was occupied at a minimum during summer seasons, however, as the entire artifact assemblage portrays, the site was likely occupied year-round. Ceramic artifacts are a temporal indicator of Late Period occupation at site CA-SDI-8303. A total of 449 ceramic sherds was recovered as a result of the present Indexing and Preservation Study at CA-SDI-8303. The large quantity of ceramics, and the presence of two different types of ceramic wares (Tizon Brown Ware and Lower Colorado Buff Ware) suggest intensive use of ceramics during the Late Period occupation of this site. Ceramics are believed to have been infroduced into the San Diego region post AD 900 (Waters 1982). At or around AD 900, during the Patayan II Period, the use of ceramics spread to a wider area and into new regions. These new regions included northem tenitories, such as along the Colorado River to southem Nevada, east to Agua Caliente along the Gila River, and west towards the Peninsular Range. Before this diffusion, ceramics were not present in the San Diego region (Waters 1982). Archaeological data suggests that the inception of ceramics in northem San Diego County occurred subsequent to the inception of ceramic manufacture in southem San Diego County (Meighan 1954; Rogers 1936; Tme and Waugh 1983). t Meighan (1954) originally defined Late Period sites within northem San Diego County as part of the San Luis Rey cultural complex. Meighan (1954) divided this complex into two phases (San Luis Rey I and San Luis Rey II) characterized by the presence or absence of ceramic artifacts within the cultural material deposits. Meighan (1954) stated that Late Period sites lacking ceramic artifacts dated to AD 1400 to AD 1750, while Late Period sites that included ceramic artifacts dated to AD 1750 to AD 1850. Tme and Waugh (1983) substantiated Meighan's statement with their work along Frey Creek, stating that considerable ceramic use did not occur in the northem portion of San Diego County untU post AD 1750. PJ. 4-04 6-5 August 2005 However, additional archaeological work conducted within the northem portion of San Diego County does not support Meighan (1954) and Tme and Waugh's (1983) time periods. Archaeological excavations conducted by Harvey (2001), Robbins-Wade (1988), Tme et al. (1974), and York and Kirkish (2000) in northem San Diego County suggest that ceramic manufacture and use in northem San Diego County occurred as early as AD 1200 to AD 1300, and was most likely a common cultural practice by AD 1500 to AD 1600. 6.2.2 CA-SDI-8694 Radiocarbon analysis as a result of this study produced four dates placing site occupation for CA-SDI-8694 during both the Early Period (Middle Holocence), circa 5550 BC to 4450 BC (see Section 4.12), and the Late Period, circa AD 1000 to AD 1910 (see Table 6-1). One additional radiocarbon date (Beta 125792) obtained in 1999 identifies Early Period occupation from circa 5,160 to 5,310 years ago (GaUegos et al. 1999). The Early Period component- is additionally supported by the presence of a quartz atlatl dart point, and the invertebrate faunal assemblage demonstrating use of the site during the period wherein Agua Hedionda Lagoon was deep, flushing, and open to the ocean. Late Period occupation, is additionally supported by the presence of small anow points, ceramics, Donax sp. shell, and Obsidian Butte obsidian. The four otolith specimens were identified as Genyonemus lineatus (white croaker), and Roncador stearnsii (spotfin croaker), and represent fish captured during the summer (May to October). Therefore, at a minimum, the site was occupied during summer seasons. Given the radiocarbon dates, there were two periods of occupation. The first occupation dates from circa 5,160 to 7,500 years ago. The later reoccupation of CA-SDI- 8694 dates from circa 100 to 950 years ago. 6.2.3 CA-SDI-8797 Radiocarbon analysis as a result of this study produced three dates for CA-SDI-8797 Locus C (see Table 6-1). These dates place occupation primarily during the Early Period (Middle Holocene), circa 3,220 to 5,270 years ago (see Section 5.9). In addition, a Late PJ. 4-04 6-6 August 2005 Period occupation is supported by a radiocarbon date identifying a reoccupation of the site from circa 80 to 300 years ago. Previous work and this study produced a total of six radiocarbon dates (see Table 6-1). These dates, combined with artifacts and ecofacts recovered suggest three site occupations. The first occupation, and likely the dominant occupation, occurred from circa 4,655 to 5,450 years ago, and is supported by primarily lagoonal shellfish across the site. The second occupation, and possibly a shorter period of occupation, occuned from circa 2,940 to 3,360 years ago, and is supported by a low amount of Donax sp. shell recovered. The last occupation dates from circa 80 to 300 years ago, and is supported by the presence of ceramics and a low amount of lagoonal shell. As demonsttated by the radiocarbon dates recovered from CA-SDI-8797 Locus C, the site is multi-component containing evidence of both Early and Late Period occupations. The Early Period (Middle Holocene) component is the dominant component, and is identified by radiocarbon dates, previously recovered evidence of a human burial by interment (Gallegos et al. 1999), and the presence of lagoonal shellfish species. Minor evidence of a Late Period occupation is identified by one radiocarbon date, and a low amount of ceramics recovered during previous excavations (Gallegos and Huey 1992). 6.2.4 Regional Chronology Discussion Regionally, the Agua Hedionda Lagoon area has been occupied from over 9,000 years ago to historic contact (Table 6-2). In all, 19 precontact sites near Agua Hedionda Lagoon have been radiocarbon dated. The oldest known site, UCLJ-M-15, dates to 9,020 years ago. Radiocarbon dates are fairly consistent from over 8,000 to circa 3,000 years ago, and from circa 1,700 years ago to historic contact. Only one date (circa 2,100 years ago), obtained from a transient hearth feature at site CA-SDI-12814, identifies occupation from circa 3,000 to 1,700 years ago. The near absence of radiocarbon dates for the period between 3,000 to 1,700 years ago may reflect the silting in of Agua Hedionda Lagoon circa 3,500 years ago, an event that occuned at Batiquitos Lagoon during that period (Miller 1966; Wanen et al. 1961; Wamen and Pavesic 1963; Gallegos 1985, 1987; and Masters 1988).

Which reduction sfrategies were used to produce which tools? Are these sfrategies the same or different? What ground stone implements were recovered, and are they formed or expedient tools? If ground stone tools are present in the artifact assemblages for the sites, are the nodule materials local or non-local? Is there evidence that ground stone tools were produced at the sites, or were they produced elsewhere prior to being carried to the sites? 6.3.1 CA-SDI-8303 The analyzed debitage assemblage for CA-SDI-8303 provides an example of a site wherein the last stages of metavolcanic nodule core reduction (and possibly Topaz Mountain core reduction) occuned. The primary flintknapping activify was associated with metavolcanic nodule core reduction, and the predominant aspect of nodule core reduction was the production of a few late stage flake blanks, most likely for unmodified flake tools and potentially bifaces. Selection of metavolcanic nodule core toolstone, nodule core platform preparation, nodule core decortication and manufacture, and extensive nodule core reduction did not occur at this site. Only late stage flake blanks were produced at this location. Quartz, chert, and obsidian flakes also support this technological observation conceming metavolcanic nodule core reduction. Based upon the analyzed debitage sample from CA- SDI-8303, flintknapping activities were limited to: nodule core flake blank production; minimal thinning and shaping of small bifaces by percussion and pressure; resharpening of adzes (SEUTs) that may have been laterally cycled from exhausted flake cores; and, resharpening of manos and metates with battered implements that may have also been laterally cycled from exhausted nodule and Topaz Mountain flake cores. Based on the lithic assemblage at CA-SDI-8303, this site likely served as a habitation site (Table 6-3). Flake production, using local metavolcanic nodule sources, occurred at the PJ. 4-04 6-9 August 2005 Table 6-3 Cultural Material Recovered from CA-SDI-8303, CA-SDI-8694, and CA-SDI-8797 Locus C (This SUidy) Cultural Material CA-SDI-8303 CA-SDI-8694 CA-SDI-8797 Locus C Total Biface 6 0 0 6 Biface AP 9 4 0 13 Biface Preform 1 0 0 1 Flake Blank 1 0 0 1 Flake Tool 6 7 1 14 Flake Knife 1 0 0 1 Nodule Tool 1 8 0 9 Steep-Edged Unifacial Tool 3 4 1 8 Flake from Steep-Edged Unifacial Tool 2 10 17 29 Core/Bipolar Core 3 5 2 10 Tested Raw Material 0 1 0 1 Debitage 3887 2367 337 6591 Hammerstone 0 1 0 1 Battered Implement 10 21 2 33 Battered Implement Flake 18 19 2 39 Mano 19 61 4 84 Metate 5 6 0 11 Ground Stone 6 18 1 25 Polished Stone 1 0 1 2 Shaped Stone 0 1 0 1 Quartz Crystal 1 0 0 1 Pitch 1 0 0 1 Ceramic 449 260 0 709 Olivella sp.

Woodworking also played a role in site activities as supported by the recovery of three SEUTs, and two unifacial resharpening flakes. Biface reduction was not well represented in the overall artifact assemblage at CA-SDI- 8303. Twenty-eight Stage 3 flakes recovered represent biface manufactiire at tiiis site. In general, these flakes were small and poorly formed indicating that bifaces were small, thick, most likely asymmetrical, and well within the arrow point size range. Pressure flaking was represented at this site by 36 (5.5% of the technologically diagnostic debitage) Stage 4, early pressure bifacial thinning flakes (400.E-). These flakes were quite small and may represent biface edge rejuvenation and/or resharpening. Hunting activities are represented by the presence of nine anow points and four anow point fragments (see Section 3.5.1). The processing of plant material and other similar activities are represented by 30 milling tools (19 manos/mano fragments, 5 metates/metate fragments, and 6 ground stone fragments). Ground stone tools are associated with the processing/milling of seeds, nuts (acoms, walnuts, holly leaf cherry), and small mammals. Ground stone implements may include a wide range of objects used or created by the processes of abrasion, impaction, or polishing (Adams 2002). In addition, ethnographic evidence indicates that bone, clay, and pigments may have also been processed with tiie same tools (Gayton 1929; Kroeber 1925; and Spier 1978). Implements of this type may be identified by the wear pattem developed through milling stone against stone. This process often resuhs in a smooth to polished surface depending on the substance ground, and the type of lithic material used. Often, these surfaces are pecked or resharpened when ground too smooth. This activify is also supported by the presence of 10 battered implements and 18 attiition flakes from the use of those implements. Milling tools are sometimes shaped into a desired form by pecking, grinding, or flaking. The ground stone artifacts present at CA-SDI-8303 reflect a doniinant frend toward the prolonged use of local groimd stone materials, as little evidence of shaping was noted. PJ. 4-04 6-11 August 2005 The presence of four large block metate fragments provides additional evidence of a longer period of site occupation. Some of the ground stone specimens display evidence of thermal damage, and may have been recycled for use in fire hearths and/or earth ovens. Although milling tools reflecting plant collecting and processing are present, they only reflect a portion of the subsistence activities that took place at CA-SDI-8303. Additional activities included hunting, fishing, and collecting of shellfish. 6.3.2 CA-SDI-8694 Based on the lithic assemblage from CA-SDI-8694, flintknapping activities were limited to: nodule core flake blank production; minimal thinning of well-made bifaces by percussion and pressure; resharpening of adzes (SEUTs) that may have been laterally cycled from exhausted flake cores; and, resharpening of manos and metates with battered implements that may have also been laterally cycled from exhausted flake cores. The analyzed debitage assemblage from CA-SDI-8694 (similar to CA-SDI-8303) provided an example of a site wherein the last stages of nodule core reduction (and possibly Topaz Mountain core reduction) declined. As with GA-SDI-8303, the primary flintknapping activify that occuned at CA-SDI-8694 was associated with nodule core reduction, and the predominant aspect of nodule core reduction was the production of late stage flake blanks, most likely for unmodified flake tools and potentially bifaces. The 4 SEUTs and 10 adze flakes recovered from CA-SDI-8694 support on-site woodworking activities. Adzes, effective woodworking tools (Gallegos et al. 2002; Gallegos et al. 2003), are typically "...circular or semi-circular in outline form and have a low profile for the frontal view with the contiguous planer use-wear located near the working elemenf' (Schroth and Flenniken 1997). Based upon the resharpening debitage (1005.AZ-Flake), fimctioning adzes, manufactured directly from a metavolcanic nodule that produced nodule core reduction debitage, and/or were laterally cycled exhausted cores, were erriployed at this site as woodworking tools. In addition, the recovery of seven flake tools supports minimal woodworking activities. PJ. 4-04 6-12 August 2005 Hunting activities are represented by the presence of one anow point and one dart point in the artifact assemblage. The processing of plant material and other similar activities are represented by 85 milling tools (61 manos/mano fragments, 6 metates/metate fragments, and 18 ground stone fragments), 22 battered implements, and 19 battered implement flakes (see Table 6-3). The battered implements and battered implement flakes represent maintenance of milling tools (i.e., metates and manos). The ground stone artifacts present at CA-SDI-8694 reflect a dominant ttend toward the expedient use of local ground stone materials, as little evidence of shaping was noted. The presence of six large block metate fragments provides additional evidence of a longer period of site occupation. Some of the ground stone specimens display evidence of thermal damage, and may have been recycled for use in fire hearths and/or earth ovens. The larger milling assemblage recovered from CA-SDI-8694 suggests that the inhabitants of the site had some dependence on food packages that required milling for processing (i.e., grass seeds). It is evident that a large portion of the diet of the inhabitants of CA-SDI-8694 was derived from plant foods that required milling technology for consumption. 6.3.3 CA-SDI-8797 Based on the lithic assemblage from CA-SDI-8797 Locus C, flintknapping activities were limited to minimal nodule core flake blank production, minor adze resharpening, and minor mano/metate resharpening (similar to CA-SDI-8303 and CA-SDI-8694). Therefore, site activities involved limited use of unmodified flake tools, woodworking adzes, and milling of plant/animal resources on metates. It should be noted that an additional interpretation of the CA-SDI-8797 Locus C flaked stone assemblage is that all of the debitage, with the exception of two battered implement flakes and two bipolar cores, was related solely to adze maintenance. Potentially, of the 337 flakes and flake fragments, all but 17 adze production flakes, were adze preparation, reshaping, and resharpening debitage removed after or before the adze was used, and acquired the distinctive edge polish associated with adze flakes. Nodule cores and adzes PJ. 4-04 6-13 August 2005 are the same morphological artifact class, produced by the same reduction sequence, but served very different fiinctions. Furthermore, nodule cores and adzes may have been within the same reduction frajectory in that once the nodule core became "exhausted" for flake blank production, they may have been laterally cycled, with minimal alteration, into adzes. Milling implements recovered from CA-SDI-8797 Locus C include four manos/mano fragments and one ground stone fragment (see Table 6-3). In addition, milling activities are represented by two battered implements and two attrition flakes from battered implements. Battered implements have been technologically identified through replication studies (Flenniken et al. 1993) as percussion tools used to resharpen milling surfaces that have been ground too smooth. The ground stone artifacts present at CA- SDI-8797 reflect a dominant trend toward the expedient use of local ground stone materials, as little evidence of shaping was noted. Some of the ground stone specimens display evidence of thermal damage, and may have been recycled for use in fire hearths and/or earth ovens. The relatively small milling assemblage from CA-SDI-8797 Locus C suggests that the site inhabitants had a minimal dependence on food packages that required milling for processing (i.e., grass seeds), or that sample bias is causing an inaccurate reflection ofthe site. Additionally, it is evident that a large portion ofthe diet of the inhabitants of CA-SDI-8797 was derived from other resources that did not require milling technology for food processing. 6.3.4 Regional Lithic Technology Discussion The analyzed debitage assemblage from all three sites (CA-SDI-8303, CA-SDI-8694, CA-SDI-8797 Locus C) suggests nearly identical lithic technology ttajectories across ,time. Each site provides an example of a site wherein the last stages of nodule core reduction occurred. The focus of nodule core reduction was the manufacture of late stage flake blanks, most likely for unmodified flake tools, and potentially for bifaces as well. The reason for the similarify in technology across time is not clear. However, it is likely that tiie prehistoric inhabitants of the Agua Hedionda Lagoon region were working within the consfr'aints of the local raw lithic material. Technologically, tiiere are a limited PJ. 4-04 6-14 August 2005 number of ways to approach any given raw material form that produces viable end products. As stated earlier, this simple and expedient technology may have also been so commonly used because it provided a simple and relatively effortless way to produce useful flakes and flake blanks intended for immediate use or for fiirther reduction. In light of the abundance of nodule materials, it is probable that there was often little need for more material-efficient, and consequently more time-consuming reduction ttajectories. Given the abundance of nodule material in drainages and along the local coastline throughout time, and the efficiency of the technology, it is probable that there was little or no pressure to force a change in the technological approach to the locally available nodules. Although the initial reduction processes identified at all three sites are for the most part identical, it is in the formed tools that we see a divergence in technological patteming. For instance, at CA-SDI-8303 there appears to be a greater emphasis on the production of anow points, and a diminished focus on the use of adzes (SEUTs) as compared to CA-SDI-8694 and CA-SDI-8797. The lithic assemblage for CA-SDI-8303 also demonsfrates less dependence on plant material processing as compared to site CA-SDI-8694, which contains an extensive milling assemblage. This large assemblage suggests a more intense focus on plant material exploitation at CA-SDI- 8694. The shift in focus away from plant material is additionally supported by a higher volume of vertebrate faunal remains at CA-SDI-8303, perhaps explaining the greater frequency of anow points at the site. Although all of the formed tools from all three of the sites may have emanated from nodule core reduction technologies, it is the end products (tools), and ratios thereof, that reveal differences in the importance of various technologies through time and across sites. As the artifact assemblages from sites CA- SDI-8303, CA-SDI-8694, and CA-SDI-8797 Locus C porttay, the method used to reduce raw lithic material appears to have remained fairly consistent over time, whereas the tools produced shifted and evolved. 6.4 DEET/SUBSISTENCE STRATEGY • What subsistence sttategies are represented? PJ. 4-04 6-15 August 2005 6.4.1 CA-SDI-8303 Given the presence of anow points, shellfish remains, vertebrate faunal remains, and milling equipment, it is clear that the inhabitants of CA-SDI-8303 were dependant on a wide range of resources for subsistence. Hunting activities are supported by the recovery of both projectile points and faunal remains (Table 6-4). The dominant faunal remains recovered are small mammal (80%) including Lepus califomicus (black-tailed ]ackra\)hit), Spermophilus beecheyii (Califomia ground squinel), Sylvilagus audubonii (desert cottontail rabbit), and Sylvilagus bachmani (bmsh rabbit). Additional resources recovered include fish (17%)), Odocoileus hemionus (mule deer), Callipepla californica (Califomia quail), medium mammal, marine mammal, snake, and turtle. All of these species were likely hunted for subsistence purposes. They may have been hunted using a variefy of techniques including the use of nets, traps, and projectiles. The mule deer were likely hunted near the adjacent canyon areas of CA-SDI-8303, while rabbits may have been hunted in a multitude of locations. In addition, the large amount of shellfish identified in the site artifact assemblage, and the dominance of sandy beach (i.e., Donax sp.) habitat exploitation (71%), followed by bay/lagoon/estuary (i.e., Argopecten sp., Chione sp., and Ostrea lurida) habitat exploitation (28%)), suggest frequent visits to the open coast and to Agua Hedionda Lagoon to acquire shellfish (Table 6-5 and Figure 6-2). In addition to tenestrial species, a wide range of marine species are represented at CA- SDI-8303 including Galeorhinus zypoterus (soupfin shark), Genyonemus lineatus (white croaker), Myliobatis californica (hat ray), Paralichthys califomicus (Califomia halibut), Rhinobatos productus (shovelnose guitarfish), Roncador stearnsii (spotfin croaker), Sardinops sagax (Pacific sardine), Semicossyphus pulcher (Califomia sheephead), and Thunnus alalunga (albacore). The various fish species may have been obtained in a variefy of ways that rarely provide lasting evidence in the archaeological record. Fishing techniques may have included the use of fishing nets, hooks, or perhaps fishing weirs. In addition, ethnographic data states that, "On San Diego Bay tule balsas were used," and "...perhaps canoes also" (Kroeber 1925). Luomala (1978) also states that the Diegueno had tule balsas and fished with "bows, nets, hooks, and other devises." This theory is supported by the presence of some outercoastal species such as Thunnus alalunga PJ. 4-04 6-16 August 2005 Table 6-4 Summary of Vertebrate Remains for CA-SDI-8303, CA-SDI-8694, and CA-SDI-8797 Locus C (This Study) Specimen Common Name CA-SDI-8303 CA-SDI-8694 CA-SDI-8797 Specimen Locus C Total Percent Total Percent Total Percent Callipepla californica Califomia Quail 1 0.0% 0 0.0% 0 0.0% Canis latrans Coyote 1 0.0% 1 0.1% 0 0.0% Clemmys marmorata Southwestem Pond Turtle 4 0.1% 6 0.6% 0 0.0% Embiotoca sp.

(abalone) fishhook recovered from a previous excavation at CA-SDI-8303 (Gallegos et al. 1999). Other subsistence activities present at CA-SDI-8303 include milling of seeds and game for protein. This is evidenced by the presence of milling tools and battered implements. The variefy and quantify of species, and the environments they represent suggest that the inhabitants of CA-SDI-8303 relied on a wide range of plants and animals for their daily sustenance. 6.4.2 CA-SDI-8694 Given the presence of anow points, shellfish remains, vertebrate faunal remains, and milling equipment, it is clear that the inhabitants of CA-SDI-8694 were dependant on a range of resources for subsistence. Hunting activities are supported by the presence of projectile points, residue analysis, and the recovery of faunal remains including Canis latrans (coyote), Lepus califomicus (black-tailed jackrabbit), Odocoileus hemionus (mule deer), Spermophilus beecheyi (Califomia ground squinel), Sylvilagus audubonii (desert cottontail), Sylvilagus bachmani (bmsh rabbit), and Thomomys bottae (Botta's gopher) (see Table 6-4). Small-sized mammals including Lepus califomicus, Spermophilus beecheyi, Sylvilagus audubonii, Sylvilagus bachmani, and Thomomys bottae were the primary dietary animal foods, followed by large mammal (20%), fish (6%), medium mammal (3%), reptUe (l%o), and avian (less than 1%). AU of these species may have been hunted using a variefy of techniques including the use of nets, ttaps, and projectiles. The mule deer were likely hunted near the adjacent canyon areas of CA-SDI-8694 with projectiles (as evidenced by the residue sample from specimen CA-SDI-8694-303), while rabbits may have been hunted in a multitude of locations. Based on the few projectile points recovered, the majorify of tenestrial-based hunting was likely performed using nets, rabbit sticks, or fraps. In addition to terrestrial species, fish were also obtained for subsistence at CA-SDI-8694. A wide range of species are represented at the site including Galeorhinus zyopterus (soupfin shark), Genyonemus lineatus (white croaker), Myliobatis californica (bat ray), Paralichthys califomicus (Califomia halibut), Rhinobatos productus (shovelnose guitarfish), Roncador stearnsii (spotfin croaker), Sarda chiliensis (Pacific bonito). PJ. 4-04 6-20 August 2005 Semicossyphus pulcher (Califomia sheephead), and Thunnus alalunga (albacore). The various fish species may have been obtained in a variefy of ways including fishing nets, hooks, weirs, and through the use of tule balsas as discussed previously for site CA-SDI- 8303. The use of the tiile balsas is supported by the presence of some outercoastal species such as Thunnus alalunga (albacore), and by the presence of a composite fishhook or a fishing toggle within the artifact assemblage from CA-SDI-8694. In addition to the vertebrate assemblage, the large amount of shellfish identified in the site assemblage, and the dominance (99%) of lagoon species (i.e., Argopecten sp., Chione sp., and Ostrea lurida), suggest frequent visits to the nearest lagoon habitat (Agua Hedionda Lagoon) for shellfish with a minor emphasis of exploitation along the open coast (see Table 6-5 and Figure 6-2). Given the amount of shellfish recovered, shellfish was an important confributor to the diet of the inhabitants of CA-SDI-8694. Lastly, the large milling assemblage, including milling tools and battered implements, identifies the milling of plant seeds and game for protein. The milling assemblage recovered from CA-SDI-8694 suggests that the site inhabitants had a sfrong dependence on plant foods that required milling for processing (i.e., grass seeds). It is evident that a large portion of the inhabitants' diet was derived from plant foods that required milling technology for consumption. The variefy and quantify of species present, and the environments they represent suggest that the inhabitants of CA-SDI-8694 relied on multiple subsistence practices for their daily sustenance. However, based on the present assemblage it is likely that the collection of shellfish from nearby habitats, the milling of plants, and the hunting of small mammals made up the majorify of subsistence activities at CA-SDI-8694. 6.4.3 CA-SDI-8797 Given the presence of shellfish remains, vertebrate faunal remains, and milling equipment, it is clear that the inhabitants of CA-SDI-8797 were dependant on a range of resources for subsistence. It should be noted that the excavation sample is small and was focused on the east portion of the site. However, hunting activities are supported by the PJ. 4-04 6-21 August 2005 recovery of faunal remains including primarily small-sized mammals (87.3%o)(see Table 6-4), followed by large mammal resources (4.2%o), avian and fish resources (2.8%)), and medium mammal and marine mammal resources (less than 1.5%) each). All of these species may have been hunted using a variefy of techniques including the use of nets, fraps, and projectiles In addition to the vertebrate assemblage, the large amount of shellfish identified in the site assemblage, and the dominance (95.2%) of lagoon species (i.e., Chione sp., Argopecten sp., Ostrea lurida, Polinices sp., and Astrea undosa), suggest frequent visits to the nearest lagoon habitat (Agua Hedionda Lagoon)(see Table 6-5 and Figure 6-2). Rocky shore/outer coast and sandy beach species also contributed to the inhabitants' diet by 4.6% and 0.2% respectively. Lastly, the milling assemblage identifies the processing of plant seeds and small game for protein. The variefy and quantify of species, and the environments they represent suggest that the inhabitants of CA-SDI-8797 relied on multiple subsistence practices for their daily sustenance. These subsistence practices included the collection of shellfish, the milling of plant foods, and the hunting of small animals. 6.5 SITE TYPE AND SETTLEMENT PATTERN • Temporally, how do these sites fit into the overall pattem for San Diego Counfy? That is, what group or culture are we examining in the context of the known culture history, and can we differentiate between periods of occupation(s)? If these sites are representative of specialized camps and/or gathering groups, what was each site's function, and how do these sites relate to other sites: as base camps, special-use sites, or as extractive sites? How did occupation and use of these sites contribute to seasonal or year-round occupation of the region in general? PJ. 4-04 6-22 August 2005 6.5.1 Site Type and Settlement Pattern for CA-SDI-8303, -8694, and -8797 It has been suggested that the pattem during the Late Period included two or more permanent base camps with a number of associated special-purpose sites, such as quarry sites, hunting blinds, and milling sites (Tme et al. 1974; Tme and Waugh 1982). The winter base camp, occupied four to six months of a year, was the location wherein most ceremonies took place. The summer-fall camp, was the acom collecting and hunting camp, and was usually located near an oak grove. During the spring, the village group was divided into smaller family groups, with each group occupying a small area wherein fresh vegetal resources could be obtained or coastal shellfish collected. The small group size compensated for the lack of resources after the depletion of the winter caches, and prior to the next year's harvest. The summer-fall camps reflected a coalescence of the kin-group with the large winter camp composed ofthe total population (Bean and Shipek 1978; Tme et al. 1974; Tme and Waugh 1981). All three sites (CA-SDI-8303, CA-SDI-8694, CA-SDI-8797) are identified as habitation sites. Sites CA-SDI-8694 and CA-SDI-8797 are primarily Early Period habitation sites occupied circa 5,000 years ago during the time when sea level was rising and Agua Hedionda Lagoon was open with ocean tidal flow. Both of these sites also have Late period occupation components demonsfrated by radiocarbon dates placing reoccupation within the last 1,000 years, and artifact assemblages that include ceramics, anow points (at CA-SDI-8694), and Donax sp. shell (a sandy beach shellfish species; suggesting closure of the lagoon and exploitation of open coast shellfish habitats). Site CA-SDI-8303 stands in conttast to CA-SDI-8694 and CA-SDI-8797, as CA-SDI- 8303 is a Late Period habitation site dated to cfrca 980 years ago to historic contact. The artifact assemblage includes ceramics, anow points, a dominance of Donax sp. shell, and obsidian from Obsidian Butte. This site also has minimal evidence of Early Period occupation supported by the presence of a low amount of lagoonal shell present in the PJ. 4-04 6-23 August 2005 basal unit levels that dated to circa 6,600 years ago, and a piece of obsidian from the Coso Volcanic Field sources. A number of Early Period sites have been recorded on ridges and tenaces adjacent to Agua Hedionda Lagoon, demonstrating that exploitation of the lagoon habitat was present in the early to middle Holocene. Late Period sites are more focused on dependable water sources, as shown by CA-SDI-8303, situated in the valley, adjacent to a spring at the head of a canyon. ^ General site patteming for the Agua Hedionda Lagoon study area can be demonsfrated using record search information (Table 6-6) and site typing. The Agua Hedionda Lagoon region was divided into two study areas to assess site-type patteming within a one-mile radius ofthe lagoon (Area 1), and a roughly four-square mile area east of Area 1 (Area 2). Areas 1 and 2 are roughly equal in size (Figure 6-3). Area 1 contains 41 sites, of which 25 (61%) are habitation, followed by 9 (22%)) artifact scatter/temporary camps, 6 (15%)) shell scatters, and 1 (2%)) ceramic scatter (Table 6-7). As can be seen in Table 6-7, Area 2 has fewer habitation sites and more special-purpose sites than Area 1. For the Agua Hedionda Lagoon study area, site patteming is shown by: 1) the high number of Eariy Period habitation sites, including CA-SDI-8694 and CA-SDI-8797 that surround Agua Hedionda Lagoon; 2) the setting of CA-SDI-8303 away from the lagoon, but near a permanent water source; and 3) the increase in special-use sites to the east, away from the lagoon. The otolith analysis identified the occupation for both CA-SDI-8303 and CA-SDI-8694, at a minimum, during the summer (May to October). During this time, most hard seeds, acoms, and other nuts are ripe for harvest. The presence of deer would also be greater at this time of year, just prior to winter rains. Mule deer migrate in response to water in the semi-arid southem areas of the westem United States (Wallmo 1978). However, given the range of subsistence materials identified at all three sites (CA-SDI-8303, CA-SDI- 8694, CA-SDI-8797), the sites may have been occupied either seasonally or year-round. As the specific boundary of the Kumeyaay and Luiseno Native Americans is unknown.

L. Tme based part of the Cuyamaca Complex on the idea that ceramic items are one of the major indicators of culture in differentiating between Kumeyaay and Luiseno sites (Tme 1966, 1970). According to Tme (1970), unlike the San Luis Rey Complex (culturally affiliated with the Luiseno), the Cuyamaca Complex (culturally affiliated with the Kumeyaay) has an emphasis on the use of ceramics, wherein a wide range of ceramic forms and different wares are present at associated sites (Tme 1970). Tme (1974) based the Cuyamaca Complex on only a handftil of sites, and stated that a detailed analysis of ceramics from different areas of the counfy was necessary to fiiUy address ceramics as a defining component within the Cuyamaca Complex (Tme 1970). Tme (1970) based this complex on data from the Cuyamaca Mountain region, and artifact analysis. However, his sample size was not representative of Late Period sites outside of the Cuyamaca Mountain region. Moreover, Tme's (1970) sample did not include the results of three major investigations (Tom-Kav, Frey Creek, and Molpa) at northem San Diego Counfy Late Period sites (Tme et al. 1974, 1981, 1991). Tme's 1970 statement has lasted through the years, and has made an impression on the research outlook of northem San Diego Counfy sites. Previous research has assumed that ceramics are only found in small quantities and without variabilify in wares and types in north San Diego County. On the confrary, the cunent research suggests that there are similarities in the types and wares between north and south San Diego Counfy sites. Three additional northem San Diego Counfy coastal sites (CA-SDI-9097, CA-SDI- 12262, CA-SDI-14784) were examined as part ofthe stiidy. Site CA-SDI-9097 is located approximately one-half mile north of sites CA-SDI-8303 and CA-SDI-8694. Sites CA- SDI-12262 and CA-SDI-14784 are located approximately 5 miles north of sites CA-SDI- 8303 and CA-SDI-8694, near the Buena Vista Lagoon. Pefrographic analysis was conducted on ceramic sherds recovered from previous test programs at sites CA-SDI- PJ. 4-04 6-29 August 2005 I I I I I I I I I I I I I I I I I 9097, CA-SDI-12262, and CA-SDI-14784 (Gallegos et al. 2000, 2001)(Table 6-8). The thin section samples and results for sites CA-SDI-12262 and CA-SDI-14784 were combined to represent one site location, as they are located adjacent to each other. Eighfy-five percent (n=44) of the ceramics recovered from site CA-SDI-9097 were identified as Tizon Brown Ware, and 15% (n=8) were identified as Lower Colorado Buff Ware. At sites CA-SDI-12262 and CA-SDI-14784, 84% (n-54) ofthe ceramics were identified as Tizon Brown Ware, while 16%) (n=10) were identified as Salton Brown Ware. In addition to the Carlsbad Municipal Golf Course project sites CA-SDI-8303 and CA-SDI-8694, these three additional sites (CA-SDI-9097, CA-SDI-12262, CA-SDI- 14784) demonsfrate ceramic ware variabilify that was formerly thought to occur only in the southem portion of San Diego Counfy. The presence of Tizon Brown Warci, Salton Brown Ware, and Colorado Buff Ware at all five sites negates the long-standing idea that sites within northern San Diego Counfy have minimal amounts of ceramic quantities and type variabilify. Additional ceramic analysis data from northem San Diego Counfy sites is required to understand the role of the desert region in regards to the foothill/mountain-coastal migration pattem. The ethnographic literature states that the Luisefio ttaveled on a seasonal basis, migrating to and from the foothill and mountains to the coast, however, little is known about travel east of the foothills and mountains. Contact through ttade and/or travel was occurring with desert groups, as is evident by the presence of desert wares at the five sites, yet there is paucify in the ethnographic literature on such frade and/or travel ties. Moreover, supplementary data is necessary on artifact assemblages from northem San Diego Counfy mountain sites. Mountain sites are considered to be the cultural ttansition area between the coast/inland and desert regions. Such mountain sites tend to have increased artifact type variabilify that is rarely seen at sites located fiirther west. For example. Mount Laguna and the Cuyamaca Mountains have extensive village sites with artifact assemblages consisting of anow points, bifaces, drills, pesties, manos, portable metates, anow shaft sfraighteners, bone tools, stone, bone, shell, and glass beads, pendants, carved effigies, ceramic pipes, pottery, and non-local lithic material (i.e., obsidian, jasper).

Furthermore, without research on trade and/or ttavel ties with eastem sites, archaeologists lack an accurate understanding of settlement type, ttade and/or travel pattems, and the chronology of the Late Period in northem San Diego Counfy. 6.5.3 Tool Forms and Culture Groups (by Tracy Sttopes) At present, archaeologists lack clear insight into the pattems of the morphology of artifacts that may have occuned within and/or across social and temporal boundaries. The archaeological literature on projectile point types suggests that point morphologies (in the present case, Cottonwood Triangular and Desert Side-notched) are clear indicators of specific culture groups and time periods. This assumption can be found throughout the archaeological literature of southem Califomia, and is simply a hypothesis that needs testing to substantiate. Point types (or ratios thereof) have often been used (and still are used) to assign specific cultural affiliation and temporal placement to a specific site. If point morphology could identify cultural affiliation, then Kumeyaay would be placed in Alabama, New Mexico, Arizona, Texas, and Illinois (to name a few) at various times in the Late Period; and, the Luiseno would be placed across the United States. The taxonomies that sprang from the proliferation of archaeology in the Great Basin in the 1950s manifested as two umbrella morphological types, known as Desert Side- notched and Cottonwood Triangular points (Baumhoff 1957; Bettinger and Taylor 1974; Heizer and Hester 1978; Larming 1963). The literature and taxonomies of the Great Basin quickly surfaced in San Diego archaeology with the two major types prevailing (Cottonwood Triangular and Desert Side-notched series). Any variants of these forms have been defined primarily by basal morphology (Baumhoff and Byme 1959; Tme 1970; Waugh 1988). In San Diego Counfy, the study of point types as cultural and temporal markers has been based primarily on work by Tme (1970). Tme (1970) proposed that archaeological sites with a greater frequency of Cottonwood Triangular points represent Luiseno occupation (San Luis Rey sites), whereas a greater frequency of Desert Side-notched anow points would represent Kumeyaay occupation (Diegueno sites). PJ. 4-04 6-32 August 2005 I I ii Tme suggests that Kumeyaay (Cuyamaca Complex) sites display "a cultural preference for side-notched projectile points" (1970). Table 6-9 compares the frequency of Cottonwood Triangular and Desert side-notched points from 10 Luiseno and Kumeyaay sites. As shown in Table 6-9, none of the sites, including Tme's Cuyamaca type-sites, exhibit a preference for side-notched points. This comparison demonsfrates that both the Luiseiio and the Kumeyaay have a preference for Cottonwood Triangular type points. Two ofthe ten sites, one Luiseiio (CA-SDI-5641) and one Kumeyaay (CA-SDI-12809), have a somewhat even number of Cottonwood Triangular and Desert Side-notched anow points. The results of this comparative analysis suggest that point variance is more likely a function of technological needs and consttaints rather than aesthetic design. It can easily be shown that with any morphologically variable entify, as the quantify increases so does the degree of variation among "types." A more viable path to interpreting the archaeological record is the understanding that projectile points are part, of a complex'^ system that involves procurement (selection of rock for a specific purpose), production, reduction, recycling, and disposal, as reflected in the archaeological record. In addition, recent point breakage studies have proven that point typing on the basis of point bases is even more problematic. Point breakage studies by Woods (1988) and by Flenniken and Raymond (1986) provide evidence confrary to Tme's work. Woods (1988) and Flenniken and Raymond (1986) suggest that no temporal assignment (with the exception of arrow point relative to dart point) can be readily placed on objects with overlapping, chaotic, rapidly changing morphological types. Woods points out that during replicative experiments some 46% of anow point specimens propelled from a bow survived impact with enough mass to be rejuvenated and reused. Woods' (1988) study also illustrated that the "use induced macrodamage is primarily expressed at the proximal end" (the base) of the projectile point. Woods concluded, "...if reuse were desired, considerable rejuvenation to the typologically diagnostic portion of the projectile point might be required." These conclusions lead to the possibilify of fremendous variation in basal form throughout the life and reuse of the biface. This appears to hold tme for dart points and hafted lancelot forms as well.

True 1966 prehistory raises doubts about typologies that rely heavily on the basal morphology of projectile points to develop types considered to be relevant cultural and temporal markers. Therefore, a determination as' to Luiseiio or Kumeyaay occupation cannot be made based on point morphology. As stated by Flenniken (2001) regarding CA-SDI- 5633: The flaked stone reduction technology identified at CA-SDI-5633 was almost exclusively related to anow point production and rejuvenation.. .A predominance of early pressure flakes indicates original tool manufacture over bifacial tool rejuvenation. However, given that most of these toolstone materials (metavolcanic and quartz materials) are not ideal toolstones for the production of flaked stone tools, early pressure flakes may not only represent original tool manufacture, but may include rejuvenation processes...Experimental data conceming the fracture pattems and rejuvenation of projectile points employed in simulated hunting situations are well established in the archaeological literature (Flenniken 1985; Flenniken and Raymond 1986; Titinus and Woods 1986; Towner and Warburton 1990; Woods 1988). Excavation of CA-SDI-5633 produced 72 anow points, anow point fragments, and small pieces of pressure flaked bifaces that may have been portions of anow points. The spatial distribution of the anow points, point fragments, and debitage indicates site mixing. However, reusable anow points were rejuvenated, and badly broken anow points were discarded and replaced with newly made anow points. Simply stated, the presence and identification of point types does not provide sufficient data to identify cultural affiliation. The anow points recovered from CA-SDI-8303 and CA-SDI-8694 fall under the term Cottonwood Triangular for all typeable specimens. Although Cottonwood Triangular points and Desert Side-notched points appear to display some differential patteming across southem Califomia, these distributions are not well understood. What causes the actual variation in these artifacts is uncertain. At.present, a date of AD 1300 has been suggested for the development of small projectile points in southem Califomia (Yohe 1992). 6.5.4 Understanding Settlement Patterns in North San Diego County (by Tracy Sttopes) A research goal of San Diego County archaeology over the past several decades has been the typing of Late Period archaeological sites into either San Luis Rey (Luiseno) or PJ. 4-04 6-35 August 2005 Cuyamaca (Kumeyaay) complexes. Archaeologists suggest that sites typifying the San Luis Rey Complex were occupied by ancesfral Luiseno, and sites typifying the Cuyamaca Complex were occupied by ancesfral Diegueno (Kumeyaay). These complexes were first divided by Meighan (1954) into northem and southem manifestations, and fiirther defined by Tme (1966). Tme's goals in his 1966 and 1970 work were to provide a basis for professional-qualify cultural reconstmctions and detailed comparative studies. Tme's 1966 work focused on an attempt to isolate pattems that coincided with linguistic boundaries in San Diego Counfy. At the time, little effort had been allotted to the documentation of relationships between archaeological evidence, linguistic distribution, and cultural pattems. The goal of Tme's thesis was to examine the possibUities for the documentation of such relationships in San Diego Counfy. Tme held environmental and time factors as constants, and proposed that variations in archaeological assemblages recovered from Luiseiio and Diegueno (Kumeyaay) areas were cultural in nature. Linguistic isolation and differences in worldview would therefore be reflected in the archaeological record. Tme discovered that, archaeologically, the San Luis Rey and Cuyamaca complexes were "two relatively homogeneous but culturally separable entities" (1966). Based on the data collected for his 1966 study, Tme suggested that a simplifled reconstmction of the culture histoty of San Diego Counfy could be made. From this reconstmction, the late prehistoric-protohistoric and historic segments could be segmented into two distinct pattems: the area occupied by the Luiseno in historic times; and, the area occupied by the Dieguefio (Kumeyaay). Tme's later work (1970) was an extension of his thesis, but with a greater focus dedicated to the interior upland region of San Diego Counfy, and what he defined as the Cuyamaca region. The differences between these complexes were based primarily on the archaeological record defined by Tme in 1970, and attributed to degree rather than artifact fype. Tme's definition included the hypothesis that San Luis Rey Complex sites as compared to Cuyamaca Complex sites displayed a preference for Cottonwood Triangular points over Desert Side-notched points, and that Cuyamaca Complex sites displayed a preference for Desert Side-notched points. While both San Luis Rey and Cuyamaca complex sites may contain ceramics, Cuyamaca Complex sites generally display more exotic ceramic forms, multiple vessel types, bow pipes, effigies, and rattles. Milling implements and steatite are also believed PJ. 4-04 6-36 August 2005 to be more frequently occurring in Cuyamaca Complex occupations. Tme (1970) states that fire hearths in Cuyamaca Complex sites are clay lined, cemeteries are distinct from living areas, and cremated human remains are placed in ceramic ums with offerings and markers. Tme's (1970) specific list for typical features of the Cuyamaca Complex (Kumeyaay) is as follows: 1. Defined cemetety areas apart from living areas. 2. Use of grave markers. 3. Cremations placed in ums. 4. Use of specifically made mortuary offerings such as miniature vessels, shaft sfraighteners, and elaborately made projectile points. 5. Cultural preference for side-notched projectile points, indicating a desert connection. 6. Substantial numbers of scrapers, scraper planes, and flaked tools, in confrast to small numbers at San Luis Rey sites at a contemporaneous time. 7. Emphasis placed on ceramics to include a wide range of forms and several specialized items such as rattles, bow pipes, and effigies. 8. A well-developed local steatite industry. 9. A substantially higher frequency of milling stone elements when compared to San Luis Rey. 10. Clay-lined hearths. Attempting to use Tme's descriptors of frequencies to assign a specific culture group to the archaeological assemblages of CA-SDI-8303, CA-SDI-8694, and CA-SDI-8797 becomes problematic in light of recent research. In addition, the degree of overlap between Luisefio and Kumeyaay territories as defined by Shipek (1988) and Kroeber (1925) complicates the association of archaeological sites with either Luiseno or Kumeyaay cultural affiliation in north San Diego Counfy. Shipek (1988) suggests that the Luisefio population extended north, from the drainage divide south of the San Luis PJ. 4-04 6-37 August 2005 Rey River, to the divide that separates Valley Center from Escondido. In confrast, Kroeber (1925) defines the boundaty as being located just south of Agua Hedionda Lagoon, and northeast to Mesa Grande. According to Kroeber's (1925) definition, the three sites from this study are located within Luiseno tenitoty during the Late Period. As stated previously, projectile point forms are inherently morphologically chaotic, and can change dramatically within a short period of procurement, production, use, and recycling. A comparison showing frequencies of point types for CA-SDI-8303 and selected San Diego Counfy sites was previously discussed in Section 6.5.3. Although few typeable projectile points (nine from the present study and three from the Gallegos et al. 1999 stiidy) were recovered at CA-SDI-8303, ceramics are present. However, the CA-SDI-8303 and CA-SDI-8694 assemblages maintain some of the complexify that is suggested by Tme for a Kumeyaay assemblage. Based on Tme's work, the cultural placement of the present assemblages would be uncertain. Tme (1970) based his thesis on data recovered from the Cuyamaca Mountain region, and artifact analysis. However, his sample size was not representative of Late Period sites outside of the Cuyamaca Mountain region. Moreover, Tme's (1970) sample did not include the resuhs of three major investigations (Tom-Kav, Frey Creek, and Molpa) at northem San Diego Counfy Late Period sites (Tme et al. 1974,1981, 1991). A better example of the complexify of this problem is CA-SDI-11068 (Twin Oaks Ranch), a Luisefio site, located northeast of the project area. CA-SDI-11068 (Schroth and Gallegos 1991) contains a greater frequency of Cottonwood Triangular points than Desert Side-notched points, thereby assigning this site to the San Luis Rey Complex. In conttast, CA-SDI-11068 contains a high number of ceramics that include exotic forms, multiple vessel types, bow pipes, and effigies, and a wide variety of milling implements, thereby assigning this site to the Cuyamaca Complex. Late Period site CA-SDI-5353 (Koerper 1986) cannot be typed using Tme's cultural definitions either, as this site also has a higher frequency of Cottonwood Triangular PJ. 4-04 6-38 August 2005 points (thereby assigning it to the San Luis Rey Complex); and ceramics representing multiple vessel forms and bow pipes, and a high number of milling tools that would identify assignment to the Cuyamaca Complex. . In comparing the villages of La Rinconada de Jamo to CA-SDI-8303, the artifact assemblage from La Rinconada de Jamo contains a higher frequency of Cottonwood Triangular to Desert Side-notched (29:1) points, placing this site in the San Luis Rey Complex (Luisefio). However, ethnographically the site is documented as Kumeyaay (Kroeber 1925; Can-ico 1986). Another example of trying to type cultures to sites by presence of selected artifacts is demonsttated at the Village of Ystagua. On the basis of Tme's point types, this site would be placed in the San Luis Rey Complex; however, this site contains ceramics, steatite, and milling equipment, and is clearly within Kumeyaay territory, thereby placing it within the Cuyamaca Complex. As noted by the previous examples, the use of predetermined ttaits set forth by Tme (1970) for San Luis Rey and Cuyamaca complexes is highly problematic. A more appropriate means of understanding sites within San Diego Counfy may be gained using a greater awareness of the resources exploited regionally rather than what was made from them. The resources themselves are fixed in space and do not change or move until someone chooses to select and fransport the items. The distance they may fravel, or the degree to which they are exploited is often relative to the economic needs of the groups. For instance, when viewing the assemblage of CA-SDI-8303, the dominant lithic materials are local; however, obsidian from the Obsidian Butte source is present. Was the obsidian a ttade item, or did the inhabitants of CA-SDI-8303 fravel to acquire this non-local lithic material? In addition, a great deal of insight can be gained by looking at the mineralogical breakdown of ceramic artifacts to determine resource acquisition, and to define cultural territories. PJ. 4-04 6-39 August 2005 6.5.5 Summary Based on the presented range of issues, can the sites from this study be placed within a temporal settlement system for contrast with other earlier or later settlement systems? The answer to this question is problematic. If the researcher relies on the cunent formula for assigning cultural affiliation to archaeological sites, then placement can be given. However, the cunent formula does not take into account the dynamic nature of artifact assemblages or the inhabitants who produced the artifacts. A better understanding of material sources and exploitation practices will reveal new models for settlement and subsistence pattems of the inhabitants of the San Diego region over time. Settlement and subsistence pattems proposed for the Luisefio include Oxendine (1983), Waugh (1986), Quintero (1987), and Christenson (1989). In 1986, Waugh analyzed three inland sites in an attempt to define subsistence and settlement activities for the Luisefio culture area. Using both faunal and floral data, Waugh concluded that "...at a seemingly late date, and as a result of proposed increased pressure on access to critical resources, a shift in subsistence sfrategies was marked by an emphasis on the acom and a pattem of more intensified land use" (Waugh 1986). The three sites were dated using varied determinants, from Milling Phase to San Luis Rey I. Waugh states that a continuation, modification, and elaboration of the conclusions are expected for the Late Period Luiseno. Resource based seasonal camps were the focus of the subsistence sttategies. Upland sites were seasonally occupied, with acoms the subsistence focus. Storage of acoms allowed for intensified use of lowland sites, with available water the focus for site placement. Only one site contained shell and none of the sites contained fish bone, leaving open the question of how coastal Luiseno sites fit into this settlement model. Quintero (1987) analyzed the inland Deer Springs site, which contained evidence of numerous coastal resources. The focus of Quintero's analysis was faunal material. Through seasonalify measurements of varied faunal resources, Quintero concluded that the site occupants had "...seasonally scheduled coastal exploitation and seasonal inland village site occupancy." The data was based on one site that was very rich in cultural PJ. 4-04 6-40 August 2005 remains, and the results were not compared with the coastal phase of the seasonal pattem to verify results and conclusions. Waugh tested both of these models with CA-ORA-910A. While Waugh (1986) acknowledged seasonal exploitation and proposed that resource use intensified as population pressures increased, no seasonalify determinations were made. Additionally, no discussion was presented regarding the presence of shell at one of the sites included in the study. However, the shell was present in quantities sufficient enough to indicate purposeful transportation from the coast to the inland site, rather than a few pieces of shell (some possibly from omaments) present from exchange with coastal groups or imported by the site inhabitants from a coastal location. Quintero's (1987) model proposes movement from the inland Deer Springs site to the coast for fishing and shellfish gathering. While Quintero's seasonalify analysis confirms seasonal use of the Deer Springs site, a contemporaneously dated, seasonally occupied coastal site would sfrengthen Quintero's model. CA-ORA-910A, a short-term habitation coastal site contemporaneous with the Deer Springs site, contains a low amount of large and small mammal bone, but demonstrates a seasonal maritime subsistence segment based on specific marine mammals and fish. The settlement pattem as modeled by Waugh (1986) is supported by evidence from three sites. Seasonally focused sites are found on the coast (CA-ORA-910A); inland at sites like Deer Springs; and at acom gathering sites in the uplands (Waugh 1986). Binford (1980) produced a mobilify sfrategy continuum for hunter-gatherers that identified foragers who employed residential moves among a sequence of resource patches at one exfreme. At the other end of the continuum were collectors, who restricted residential mobilify in favor of movement by task-specific groups. The importance of Binford's continuum is that it sfressed variabiUfy. As proposed by Binford (1980), the forager/collector continuum does not represent two exclusive categories, but rather hunter/gatherer subsistence activities ranging between the two exfremes. Thomas (1983) built upon this continuum by emphasizing variabilify in the settlement and subsistence PJ. 4-04 6-41 August 2005 system in Monitor Valley, rather than uniformify. Thomas showed how the archaeological evidence could have three separate interpretations, each of which is a part of the forager/collector continuum. CA-SDI-8303, CA-SDI-8694, and CA-SDI-8797 could have been seasonally occupied sites, wherein vegetal resources were collected, game was hunted and/or trapped, a range of seafood was netted and/or fished, and shellfish was collected. Altematively, they could have been permanent habitation sites from which special-purpose task groups were organized to conduct these activities. 6.6 TRADE AND TRAVEL • To what extent is frade and fravel evidenced at the three sites? Do the sites contain imported or fraded lithic materials such as steatite, obsidian, chert, chalcedony, and/or jasper? Can these materials be sourced to specific locations? 6.6.1 Trade and Travel for CA-SDI-8303,-8694, and-8797 Several material types present in the collections suggest that trade and/or contact with other groups was an important aspect of the lives of the inhabitants of CA-SDI-8303, CA-SDI-8694, and CA-SDI-8797. It has been proposed that the early frade networks for the coastal southem Califomia region were primarily to the north, while latter period trade networks were primarily to the east and desert regions (Hughes and Tme 1985; Ericson et al. 1989). The obsidian samples from CA-SDI-8303 seem to support these assumptions. Four of the obsidian specimens recovered provided trace element concenttations geochemically placing volcanic glass origins to Obsidian Butte located in Imperial Counfy, Califomia. An additional obsidian specimen provided ttace element concentrations geochemically placing its volcanic glass origin to the Coso Volcanic Fields located in Kem Counfy, Califomia. The remaining non-local materials from these sites include chert (fraded from either the north or east), Monterey chert (traded from the north), and Piedra de Lumbre chert (fraded from the Camp Pendleton area). Obsidian PJ. 4-04 6-42 August 2005 was also present at CA-SDI-8694, but was too small to source. The present study recovered no obsidian from CA-SDI-8797 Locus C. 6.7 CERAMIC DISCUSSION (by Monica Guenero) The results of the ceramic analysis for sites CA-SDI-8303 and CA-SDI-8694 provided data on the geologic location of clay sources that were used to manufacture pottery. Results of the petrographic analysis indicate that 98% (n=284) of the sherds recovered from site CA-SDI-8303 are Tizon Brown Ware, and 2% (n=5) are Lower Colorado Buff Ware. Results of the pefrographic analysis for site CA-SDI-8694 indicate that 70%o (n=177) of the sherds recovered from the site are Tizon Brown Ware, 25% (n=63) are Salton Brown Ware, and 5% (n = 12) are Lower Colorado Buff Ware. The presence of Lower Colorado Buff Ware ceramics indicates that frade and/or travel occuned to the former lake bottom and alluvial deposits in the Colorado Desert and Imperial Counfy, near ancient Lake Cahuilla. The presence of Salton Brown Ware suggests frade and/or fravel to the east side of the Peninsular Range (Westem Salton Trough). Although Tizon Brown Ware ceramics are considered local wares throughout the San Diego region, the clay sources were still approximately 6-10 miles east of sites CA-SDI-8303 and CA-SDI- 8694, suggesting that a degree of fravel and/or trade was necessary to obtain and/or manufacture these pots. These results provide important clues regarding the inhabitants of sites CA-SDI-8303 and CA-SDI-8694. Hildebrand et al.'s (2002) study on coastal and mountain sites indicates a pattem of westward transport of Lower Colorado Buff Ware and Salton Brown Ware into the Peninsular Range and coastal regions. There was little evidence for eastward transport of ceramics from the coast to the Peninsular Range, or from the Peninsular Range to the desert. Hildebrand et al.'s (2002) study did not include ceramics from the northem portion of San Diego Counfy, and therefore, an inference is made that a westward frade and/or travel route was present in the northem San Diego region as well. PJ. 4-04 6-43 August 2005 Ethnographic information indicates that the Luiseno ttaveled on a seasonal basis, migrating in the late summer and fall to foothill and mountain sites, and fraveling to sites near the coast during winter and spring (Bean and Shipek 1978). Such movement would provide the setting for procurement of non-local clay, and wares. Additionally, trade may have fimctioned as a reaffirmation of social ties, especially regarding hunting and gathering tenitories, migration, allies, quarrying, and religious-ceremonial fimctions. As CA-SDI-8303 and CA-SDI-8694 are located near the coast, it is likely that the desert wares (Salton Brown Ware and Lower Colorado Buff Ware) were ttaded into the area, however, travel most likely occuned to some degree. Pottery vessels can be efficiently carried long distances through the use of grass canying bags and nets as long as they are not too heavy, and contain restricted vessel openings to keep the contents from spilling out (Arnold 1985; Rice 1987). Traded pottery vessels would also have served the purpose of transporting and/or trading grains, seeds, nuts and other dry goods (Rice 1987). The results of the rim sherd profiles suggest restricted vessel openings, and/or small to medium vessels, both of which indicate ttansport activities rather than cooking activities. ' 6.8 SITE SUMMARIES 6.8.1 CA-SDI-8303 Site Summary The Indexing and Preservation Stiidy for CA-SDI-8303 included field excavation of six Ixl-m units, artifact cataloguing, data analysis, and special studies. The puipose of the Indexing and Preservation Study was to provide an index sample representing the deposit to be capped and preserved. In all, the Indexing and Preservation Study at CA-SDI-8303 produced 6 bifaces, 9 arrow points, 1 biface preform, 1 flake blank, 10 battered implements, 18 flakes from battered implements, 3 steep-edged unifacial tools (SEUTs), 2 rejuvenation flakes from SEUTs, 6 flake tools, 1 flake knife, 3 cores, 3,887 debitage, 1 nodule tool, 6 ground stone fragments, 19 manos, 5 metate fragments, 1 polished stone fragment, 449 ceramic PJ. 4-04 6-44 August 2005 fragments, 12 Olivella sp. shell beads, 7 shell disc beads, 1 Cypraea spadicea Swainson (Chestnut Cowry) shell, 1 bone bead, 2 glass frade beads, 1 quartz crystal, 1 fragment of pitch, 2 otoliths, 2 bone tools, 465.4 g of bone, and 32,838.1 g of sheU. Disturbance from agricultural activities, bioturbation, and geologic activities was noted in all units. It is probable that CA-SDI-8303 maintains good site integrify. The range of artifacts at CA- SDI-8303 primarily indicates a Late Period habitation/village site occupied at a minimum during the spring and summer seasons (based on availabilify of plants, animals, and otolith analysis). Flake production from local cobbles, suggests flake tool use. Most likely, these tools were manufactured and used at the site. Hunting activities may have occurred near this site as indicated by the recovery of nine projectile points. The presence of 30 ground stone tools, and 11 battered implements identifies preparation of plant foods through pounding and/or grinding. The presence of shellfish and fish remains, and small to large mammal bone demonsfrate the wide range of foods collected, hunted, and processed. In addition, the diverse fish remains suggest a range of maritime activities performed by the inhabitants of CA-SDI-8303. Faunal analysis identified black-tailed jackrabbit, desert cottontail rabbit, bmsh rabbit, mule deer, Califomia quail, soupfin shark, white croaker, bat ray, Califomia halibut, shovelnose guitarfish, spotfin croaker. Pacific bonito. Pacific sardine, Califomia sheephead, and albacore. This collection suggests that a range of hunting and fishing activities occuned at the site. Analysis of the 33,220 g of shell identifies the majorify of shellfish species as Donax gouldii (71.6%)), Chione sp. (24.8%)) and Argopecten sp. (2.7%). This collection indicates a primary exploitation focus on sandy beach habitats by the inhabitants of CA-SDI-8363, with minimal evidence of exploitation of bay/lagoon/estuary habitats. The question of ttade and ttavel was addressed through the sourcing of obsidian to Obsidian Butte in the Imperial Valley, approximately 100 miles east/northeast of CA- SDI-8303. An additional obsidian specimen provided ttace element concenttations geochemically placing its volcanic glass origin to the Coso Volcanic Fields located in Kem Counfy, Califomia. However, the majorify of lithics used for tools were PJ. 4-04 6-45 August 2005 I I I I I I I manufactured from local materials. Ceramic analysis identified the pottery samples as Tizon Brown Ware (mountain ware) and Lower Colorado Buff Ware (desert ware). The question of chronology was addressed through the radiocarbon dating of four shell samples. This analysis and the presence of glass trade beads place the occupation of site CA-SDI-8303 primarily during the Late Period from circa AD 980 to historic contact, with minor evidence of an earlier occupation circa 4,600 years ago. 6.8.2 CA-SDI-8694 Site Summary The purpose of the mitigation program for CA-SDI-8694 was to adequately address mitigation of impacts through the completion ofthe excavation of forty-four Ixl-m units, artifact cataloguing, data analysis, and special studies. In all, tiiis work produced 4 bifaces, 5 cores, 1 piece of tested raw material, 8 nodule tools, 4 utilized flake tools, 4 steep-edged unifacial tools (SEUTs or adzes), 10 flakes from SEUTs, 2,367 debitage, 1 hammerstone, 22 battered implements, 19 flakes from battered implements, 61 manos/mano fragments, 6 metates/metate fragments, 18 ground stone fragments, 1 shaped stone, 260 ceramic fragments, 1 Olivella sp. bead, 2 bone awls, 1 bone fishing toggle, 1 bone bead, and 1 possible otolith pendant. Faunal material includes 76,492.08 g of shell, 4 otoliths, and 167.9 g of bone. Disturbance from constmction, agricultural activities, and bioturbation was noted in all units. The range of artifacts at CA-SDI-8694 indicates a habitation/village site occupied at a minimum during the spring and summer seasons (based on otolith analysis). Flake production from local cobbles, suggests flake tool use. Most likely, these tools were manufactured and used at the site. Hunting activities may have occuned near this site as indicated by the recovery of two projectile points. The presence of 85 ground stone tools, and 21 battered implements represents preparation of plant foods through pounding and/or grinding. The presence of shellfish remains, and small to large mammal bone demonsfrates the range of foods collected, hunted, and processed. In addition, the large number of fish remains suggests a range of maritime activities performed by the inhabitants of CA-SDI-8694. PJ. 4-04 6-46 August 2005 I I I I I I I I I I I I I I I I I I I Faunal analysis identified coyote, black-tailed jackrabbit, mule deer, Califomia ground squinel, desert cottontail, bmsh rabbit, Botta's gopher, soupfin shark, white croaker, bat ray, Califomia halibut, shovelnose guitarfish, spotfin croaker. Pacific bonito, Califomia sheephead and albacore. This suggests that a range of hunting, fishing, and collecting activities occuned at the site. Analysis of the 76,492.08 g of shell identifies the majorify of shellfish species as Chione sp. (7L3%o), Argopecten sp. (19.4%), Ostrea lurida (7.2%), and Polinices (0.9%). This collection indicates that the site's inhabitants likely exploited the nearest lagoon habitat (Agua Hedionda Lagoon), and occasionally visited other open coast shoreline areas. The question of trade and ttavel was addressed through the analysis of lithic materials from CA-SDI-8694, and petrographic analysis of available ceramics. The presence of Obsidian Butte obsidian and various cherts suggest possible movement or contact with nearby desert locations, and contact with the inhabitants of the southem Orange Counfy region. However, the majorify of lithics used for tool manufacture was locally procured. Ceramic analysis identified the pottety samples as Tizon Brown Ware (mountain ware), Salton Brown Ware (desert ware), and Lower Colorado Buff Ware. The question of chronology was addressed through the radiocarbon dating of four shell samples. The dates place site occupation primarily during the Early Period (Middle Holocene) circa 5,160 to 7,500 years ago. In addition. Late Period reoccupation is supported by two radiocarbon dates identifying occupation from AD 1000 to AD 1910. These dates are additionally supported by the presence of one Cottonwood Triangular arrow point and ceramics. As demonsttated by the dates recovered from the site and the shell and artifact assemblage, CA-SDI-8694 is a multi-component site with both Early and Late Period occupations. 6.8.3 CA-SDI-8797 Site Summary The Indexing and Preservation Study for CA-SDI-8797 Locus C included excavation of six Ixl-m units, artifact cataloguing, data analysis, and special studies. The purpose of the Indexing and Preservation Study was to provide an index sample representing the PJ. 4-04 6-47 August 2005 I I I I I I I I I I I I I deposit to be capped and preserved. The fieldwork resulted in the collection of 337 debitage, 2 cores, 1 flake tool, 1 steep-edged unifacial tool (SEUT), 17 flakes from SEUTs, 2 battered implements, 4 manos, 1 ground stone fragment, and 1 polished stone. Faunal materials include 8.4 g of bone and 2,353.4 g of shell. Disturbance from constmction, agricultural activities, and bioturbation was noted in all units. The range of artifacts at CA-SDI-8797 Locus C indicates a habitation site primarily occupied during the Early Period (Middle to Late Holocene). The primary flintknapping activify was nodule core reduction; and, the predominant aspect of nodule core reduction was the production of a few very late stage flake blanks, most likely for unmodified flake tools. The presence of five ground stone tools, and two battered implements implies preparation of plant foods through pounding and/or grinding. The presence of shellfish remains, and small to large mammal bone demonsttates the range of foods collected, hunted, and processed. Faunal analysis identified primarily small-sized mammals, and included Sylvilagus audubonii, and other small mammals. Analysis of the 2,353.4 g of shell recovered identifies the majorify of shellfish species as Chione sp., Argopecten sp., Ostrea lurida, Polinices, and Astrea undosa, indicating that the inhabitants primarily exploited the nearest lagoon habitat (Agua Hedionda Lagoon), and occasionally visited the open coast shoreline area. The question of ttade and travel was addressed through the analysis of the lithic materials. For the most part, tools were manufactured from local lithic materials, however, non-local lithic materials were minimally used. These materials include chert (traded from either the north or east), Monterey chert (ttaded from the north), and Piedra de Lumbre chert (traded from the Camp Pendleton area). The question of chronology was addressed through the radiocarbon dating of four shell samples. The radiocarbon dates suggest that the site may have been occupied at least three times within the past 6,000 years, with the primary site occupation occurring circa 5,000 years ago, and the most recent occupation occurring within the past 1,000 years. PJ. 4-04 6-48 August 2005 6.9 SUMMARY The Indexing and Preservation Study for archaeological sites CA-SDI-8303 and CA-SDI- 8797 Locus C was completed through sample excavation, artifact analysis and this report of findings. Both CA-SDI-8303 and CA-SDI-8797 Locus C will be protected within Open Space Easements and capped. Capping using a minimum of one-inch of sand and six to twelve inches of fill, and planting of shallow-rooted plants is recommended. Utilities (ie., water, gas, sewer) are to be placed within the fill/capping or outside ofthe Open Space Easements. For CA-SDI-8694, a data recovery program was completed for the purpose of addressing mitigation of impacts. To ensure that unanticipated finds (ie., burials, cremations, buried cultural deposits) are handled in a timely and sensitive manner, monitoring by an archaeologist and a Native American shall be conducted.
