STARCH AND ORGANIC RESIDUE (FTIR) ANALYSIS OF SAMPLES FROM SITE 48SW16996, SWEETWATER COUNTY, WYOMING

Author(s): Linda Scott Cummings; Melissa K. Logan

Year: 2010

Summary

Sediment samples from the fill of a basin house and associated features at site 48SW16996 in Sweetwater County, Wyoming, were submitted for starch analysis. Fire-cracked rock from fill of a hearth within the basin house also was tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). Radiocarbon dates suggest that the house dates to the Opal phase of the Early Archaic. Starch and organic residue (FTIR) analyses will be used to provide information concerning plant resources utilized by the occupants of the house.
