Summary

Samples were examined from twelve sites (FB 9317, FB 9324, FB 9326, FB 9330, FB

9331, FB 9334, FB 9339, FB 9385, FB 9389, FB 9390, FB 9392, FB 9393) located on Fort Bliss

in El Paso County, Texas. Twenty-two samples representing feature fill and ceramic sherds

were examined for organic residues using Fourier Transform Infrared Spectroscopy (FTIR).

FTIR analysis will examine the sediments and sherds for evidence of proteins, lipids, and/or

carbohydrates and matches with plant and animal residues in our reference library. Eleven of

the feature fill samples also were examined to recover charcoal or other charred botanic

remains for AMS radiocarbon dating. Two of the samples did not yield sufficient charcoal for

AMS dating; therefore, the sediment was processed to recover microscopic charcoal for dating.

A total of 11 AMS radiocarbon dates were obtained.
