MACROFLORAL, PROTEIN RESIDUE, AND ORGANIC RESIDUE (FTIR) ANALYSES AND AMS RADIOCARBON DATING FOR SITE 45FS2075, WASHINGTON

Samples from units in three excavation blocks at site 45FS2075 in northeast Washington were examined for charcoal and other macrofloral remains. This site appears to represent pre-contact through contact period occupations. The excavation blocks contained several diffuse hearths consisting of concentrations of fire-cracked rock and bone. Charcoal or charred botanic remains from 34 samples were submitted for AMS radiocarbon dating. In addition, six lithic artifacts were sampled for protein residues. Fire-cracked rocks from seven of the features were analyzed for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). Macrofloral, protein residue, and organic residue (FTIR) analyses will be used to provide information concerning plant and animal resources available to and utilized by the occupants of this site. A total of 34 radiocarbon dates were obtained.
