The Pleistocene Geology Of The Middle ·Portion Of The Elkhorn River Valley, W. D. Frankforter
The Pleistocene Geology Of The Middle ·Portion Of The Elkhorn River Valley, W. D. Frankforter
Papers from the University Studies series (University of Nebraska)
The present report is a physiographic and paleontologic approach to the Pleistocene history of a portion of the Elkhorn River Valley in parts of Dodge, Cuming and Stanton counties in northeastern Nebraska. The area is important for correlation of deposits between the glacial and periglacial regions. Some of the critical stratigraphic units used for correlation in the Pleistocene of these regions are present in close association with the tills and contain fossils which make possible reliable statements on contemporaneity of deposits. The subsequent geologic history and present physiographic expression of this area have been greatly controlled and influenced by the …
The Post-Kansan Geologic History Of The Lower Platte Valley Area, Gilbert Carl Lueninghoener
The Post-Kansan Geologic History Of The Lower Platte Valley Area, Gilbert Carl Lueninghoener
Papers from the University Studies series (University of Nebraska)
This investigation is essentially a geomorphological study of the lower Platte River Valley area in eastern Nebraska. The area comprises Saunders, Dodge, Washington, Douglas, Sarpy, and Cass counties. The area defined above is one of the most critically located of any for the study of the post-Kansan history of the lower Platte River Valley. It lies between the older till (Nebraskan and Kansan) borders to the west and the younger till (Illinoian, Iowan, and Wisconsin) borders to the east. Physiographic changes have therefore transpired in a strictly post-Kansan periglacial region. The Kansan till is the youngest in the area. The …

A Review Of The Daimonelix Problem, C. Bertrand Schultz
Papers from the University Studies series (University of Nebraska)
THE first paleontological expedition of the University of Nebraska State Museum was organized in the summer of 1891 and was led by Erwin H. Barbour, now Director Emeritus of the Museum. The most important and interesting discoveries made during the season were some very peculiar spiral fossils called by the field party "Devil's Corkscrews," or Daimonelix,l which were found in the Miocene deposits near Harrison in Sioux County, Nebraska. During the fifty years that have intervened scientists have tried to determine the origin of these strange forms. Several controversies arose, and although various theories have been proposed, none as yet …
