POLLEN, MACROFLORAL, PROTEIN RESIDUE ANALYSIS, AND AMS RADIOCARBON DATING AT SITE 42GR3164 ON THE PROFESSOR VALLEY RANCH, SOUTHEAST UTAH

A soil column at site 42GR3164 in the Professor Valley Ranch, southeast Utah, was
sampled for pollen and macrofloral remains. The soil column was placed in an area that is believed
to have been the location where a large comer-notched knife made of gray chert was previously
found by workers installing an irrigation pipe in a hayfield, and it appeared to be at the edge of
prehistoric site 42GR3164, which had been recorded at an earlier date. The irrigation pipe trench
was re-opened, and a concentration of charcoal and fire-cracked rock was exposed. The soil
column was taken from the trench wall, adjacent to the charcoal-rock concentration. Fill from the
charcoal-rock concentration and from a light greenish deposit surrounding a pebble found in the
trench wall also were sampled for pollen and macrofloral remains. The corner-notched knife and
another artifact previously found on the surface of the site were submitted for protein residue
analysis.
