ARCHAEOLOGY AND GEOMORPHOLOGY OF THE CLOVIS-AGE KLEIN SITE NEAR KERSEY, COLORADO

The Klein site Clovis locality consists of lithic artifacts and mammot h and horse bone that have eroded from a small, low-relief gravel ridg e disturbed by agricultural practices. The ridge is on the late Pleist ocene Kersey terrace of the South Platte River and is part of a ridge- swale landscape produced by the river as it flowed in a braided patter n across an aggrading floodplain. Two soil types, Ustoll and Aquoll, h ave formed in the fine-grained sediments that mantle the ridges and sw ales, respectively. Investigations at the Klein site and others on the Kersey terrace suggest that Paleoindian materials may be found in ass ociation with either soil.
