Abstract

Four laboratories have made more than fifty finite radiocarbon-age determinations on samples from Quaternary deposits covering a large area of the Rolling Plains. These dates span the period from the late Pleistocene Epoch (23,255 ± 2,335 yr B.P.) virtually to the present. Caran and Baumgardner (1984) described a previously unrecognized sedimentary sequence covering more than 7,800 km2 (3,000 mi2) of northwestern Texas. At the time that report was prepared, only a few relevant radiocarbon-age determinations were available. The number of reliable finite dates has now increased to more than fifty, the oldest of which is 23,255 ± 2,335 yr B.P. Older infinite dates and a few questionable finite determinations also have been obtained, some of which were reported previously by other investigators.
