| Abstract: | Analysis of continuous core and drill cuttings from drill holes was compared and correlated to data obtained from bore hole geophysical logs to obtain subsurface stratigraphic information at the Lime Creek Paleoindian site, southern Nebraska. The analysis of these bore holes indicated that sedimentary layers and a significant buried soil horizon could be correlated throughout the preserved terrace fill at the site. Geophysical information obtained in well bores in 1993 was compared to lithologic and radiocarbon data from recent core holes and then integrated with archaeological profiles and artifacts collected between 1947 and 1950. A paleotopographic analysis of the soil horizon where the majority of the artifacts were discovered was then made. This ancient living surface was found to have developed on the banks of an abandoned channel, now deeply buried, that ran parallel to modern Lime Creek about 10,000 B.P. Paleoindian people likely camped on the banks of this channel, protected from cold northerly winds by a large bluff to the north of the site. © 2000 John Wiley & Sons, Inc. |
