PHYTOLITH, STARCH, MACROFLORAL, AND ORGANIC RESIDUE (FTIR) ANALYSES OF SAMPLES FROM THE HAY-1 SITE (FS-050155229), LOS ANGELES COUNTY, CALIFORNIA

Summary

Fill samples from two prehistoric hearths and a rock alignment at the Hay-1 site, FS-050155229, in Los Angeles County, California, were examined for phytoliths, starches, macrofloral remains, and organic residues. The organic residues were analyzed using Fourier Transform Infrared Spectroscopy (FTIR). This site contains both historic and prehistoric components, and the prehistoric component includes a lithic scatter with groundstone, flaked stone tools, boulder milling features, and a quartzite quarrying locale. A radiocarbon date of 790 ± 30 BP was returned for charred material from one of the hearths, reflecting occupation during the Angeles V Phase of the Del Rey Tradition (Sutton 2010). Phytolith, starch, macrofloral, and organic residues analyses will provide subsistence information concerning plant and possible animal resources utilized by the prehistoric occupants of the site.
