STRATIGRAPHIC POLLEN ANALYSIS AT THE CRESCENT SITE (5JF148), JEFFERSON COUNTY, COLORADO

Summary

Archaeological excavation at the Crescent Shelter has spanned several decades.

Cultural components noted extend from the Late Paleoindian to the Woodland and include the

Altithermal period. The site lies along the hogback valley near Deer Creek. The site's location

along the hogbacks, as well as its stratigraphy representing occupation from Paleoindian through

Woodland made it a desirable location to examine the paleoenvironmental record for the Front

Range of Colorado. The fact that this shelter contains deposits belonging to the Altithermal

period made it more valuable, since these deposits often are lacking. Radiocarbon ages of 5155

+ 110 BP and 5680 + 110 BP were obtained from levels approximately midway in this

stratigraphic record. Stratigraphic pollen analysis was undertaken on sediments collected during

the 1981 excavations. Funding for this analysis was provided by a grant from the State of

Colorado and matching funds were provided by PaleoResearch Laboratories.
