MACROFLORAL, PROTEIN RESIDUE, AND ORGANIC RESIDUE (FTIR) ANALYSIS OF SAMPLES FROM SITES CA-SBR-9711, CA-SBR-9717, AND CA-SBR-11330, MCAGCC TWENTYNINE PALMS (PROJECT NO. 15471), SAN BERNARDINO COUNTY, CALIFORNIA

Column samples from site CA-SBR-9711 and from a hearth at site CA-SBR-11330 were floated to recover charred macrofloral remains to provide subsistence information concerning plant resources utilized at these sites. Protein residue analysis was conducted on two lithic flakes from CA-SBR-9711 and on a mano fragment from CA-SBR-9717 to determine if these tools were used for processing plant and/or animal remains. The mano fragment also was examined for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). These sites are located in the Marine Corps Air Ground Combat Center in Twentynine Palms, California, and were examined as part of the Twentynine Palms TO12 Testing and Evaluation, Project #15471. The sites represent prehistoric lithic sites with associated lithic tools/artifacts. Site CA-SBR-11330 might also represent a possible habitation site or temporary camp.
