MACROFLORAL AND ORGANIC RESIDUE (FTIR) ANALYSES AT SITE 5LR11836, COLORADO

Summary

Fill from the interior of a fire-cracked rock feature at site 5LR11836 in northern Colorado

was floated to recover macrofloral remains. Two rocks capping the feature were examined for

organic residues using Fourier Transform Infrared Spectroscopy (FTIR). Charcoal from the

feature fill yielded a date of 4180 ± 40 BP. Macrofloral analysis will be used to provide

information concerning plant resources utilized by the site occupants. FTIR analysis of the

feature rocks will look for the presence of proteins, lipids, esters, and/or carbohydrates to

identify plant and/or animal foods that might have been cooked in this feature.
