PROTEIN RESIDUE (CIEP), ORGANIC RESIDUE (FTIR), ELEMENTAL COMPOSITION (XRF) ANALYSIS, AND AMS RADIOCARBON AGE DETERMINATION OF LITHIC SAMPLES FROM THE ANZICK SITE, 24PA506, PARK COUNTY, MONTANA

The Anzick Site (24PA506) is located in the intermontane Shields River Valley in Park County, Montana. This collapsed rockshelter contains burial features and an artifact assemblage. It was discovered by construction workers in 1968 (Stockton White, personal communication, October 17, 2018). The context of the site and burial and the original provenience of the artifacts are not known. Six lithics from the artifact assemblage were submitted for protein residue, and elemental composition (X-ray fluorescence) analysis to gain insight into the lithics and their use. Organic residues that might be part of the ochre on Lithic 18 and the waxy substance on Lithic 99 were examined using Fourier Transform Infrared Spectroscopy (FTIR) to better understand both the ochre and waxy substance. The waxy substance from Lithic 99 was also submitted for AMS radiocarbon age determination.
