POLLEN AND STARCH ANALYSIS OF GROUNDSTONE, MACROFLORAL ANALYSIS OF SOIL SAMPLES, AND PROTEIN ANALYSIS OF LITHIC ARTIFACTS FROM CA-SDI-1313/14791, SAN DIEGO COUNTY, CALIFORNIA

Summary

Groundstone tools from excavation units at site CA-SDI-1313/14791 on Marine Corps Base Camp Pendleton in northern San Diego County, southern California, were washed to recover pollen and starches derived from processing activities. Various levels of unit fill were floated to recover macrofloral remains from subsistence activities, while three lithic tools were submitted for protein residue analysis to determine plant or animal resources that were processed with these tools. This site contains a moderately dense to dense deposit of lithic debitage, lithic tools, and groundstone artifacts. Previous radiocarbon dates obtained on four bone fragments represent a very early San Dieguito occupation (9410-9090 calibrated BP), typical early La Jolla I and II occupations (7440-7000 calibrated BP, 6680-6530 and 6520-6500 calibrated BP, respectively), and a common later La Jolla III occupation (2960-2865 calibrated years BP) for the area (Cummings and Puseman 2013). A more recent component appears to represent a limited interval during the Late Prehistoric period (cal BP 500-630) and likely reflects the ancestral Luiseño.
