ORGANIC RESIDUE (FTIR) ANALYSIS OF ARTIFACTS AND IDENTIFICATION OF WOOD AND CHARCOAL FROM SITES CA-CAL-2055, CA-CAL-2054, AND CA-CAL-1722 FOR THE ANGELS CAMP BYPASS PROJECT, NORTHEASTERN CALIFORNIA

Author(s): Linda Scott Cummings; Kathryn Puseman

Year: 2008

Summary

A variety of artifacts from sites CA-CAL-1722, CA-CAL-2054, and CA-CAL-2055 were

tested for organic residues using Fourier Transform Infrared Spectrometry (FTIR). These sites

are located close to one another northeast of Angels Camp in Calaveras County, California, and

date in age from the Middle Archaic through the late Recent Prehistoric II. The objective for this

analysis was to detect evidence of food processing in soapstone vessels, on fire affected rock,

a milling stone, a hopper mortar, and a pestle. Charcoal and wood recovered in flotation

samples from these three sites, as well as unburned wood from site CA-CAL-2054, also were

submitted for identification.
