A PLEISTOCENE LAKE IN THE WHITE RIVER VALLEY
Get PDFDURING the course of a field conference on the Pleistocene geology of western Nebraska, carved sediments were found in the headwater drainage of White River near Crawford, Nebraska. A reconnaissance of White River Valley revealed them to be present also in the mid-course, near Interior, South Dakota, and at the mouth, near Chamberlain, South Dakota, where the White River joins the Missouri (Fig. 1). These isolated occurrences of varves, over a distance of 240 miles, are so similar that a correlation seemed possible. Furthermore, since the varves occur within the area where Yuma artifacts are found, it was thought that there was a possibility that they might be of assistance in dating the artifacts
