Mandel, R. D., Bettis, E. A. III,, 2001. Late Quaternary Landscape Evolution in the South Fork of the Big Nemaha River Valley, Southeastern Nebraska and Northeastern Kansas (GB-11): 58 pp., size 8.5" x 11". Description: The purpose of this field trip was to present the results of a recent interdisciplinary study of late Quaternary landscape evolution in the South Fork of the Big Nemaha River valley of southeastern Nebraska and northeastern Kansas. The authors have established a detailed alluvial stratigraphic and paleoecological record spanning the past 40,000 years. Although the Holocene alluvial stratigraphic record was the main feature of the field trip, outcrops of late Wisconsinan loess, colluvium, and alluvium were examined. In addition, Pre-Illinoian till was examined at two localities. With contributions by Richard G. Baker, Department of Geosciences, University of Iowa; Glen G. Fredlund, Department of Geography, University of Wisconsin-Milwaukee; and Jeremy S. Dillon, Department of Geography, University of Kansas. In conjunction with Midwest Friends of the Pleistocene 47th Field Conference - June 2-4, 2000, Hiawatha, Kansas.
