Studies In The Geomorphology Of The Mountain Regions Of The Upper Indus Basin, Kenneth Hewitt
Studies In The Geomorphology Of The Mountain Regions Of The Upper Indus Basin, Kenneth Hewitt
GreyZone
The investigation primarily concerns contemporary geomorphological features and processes in the Upper Indus Basin, Past work, and theories of the denudation chronology of the region are described, and the broad climatic and geological setting. The bulk of the work examines characteristics of weathering, slopes and mass-movements, glacial and fluvial features in the Biafo Gyang area of the Central Karakoram. The nature and role of glacier surges and natural damming in the region are discussed. An effort is also made to support the central theme with background information and visual illustration not normally available, and a comprehensive regional bibliography is provided. …

A Middle Miocene Rhinoceros Quarry In Morrill County, Nebraska (With Notes On Hip Disease In Diceratherium), Robert M. Stecher, C. Bertrand Schultz, Lloyd G. Tanner
Bulletin of the University of Nebraska State Museum (1924–2023)
Extensive deposits of fossil rhinoceros bones have been excavated from University of Nebraska State Museum collecting localities Mo-113, -114, -115, -116, and -118 some 8 1/2 to 9 1/2 miles north of Bridgeport, Morrill County, Nebraska. The fossils were associated with other faunal elements in the lower portion of the Marsland formation (middle Miocene) of the Hemingford group. The rhinoceros is considered to be Diceratherium niobrarensis Peterson, geologic variety. A pathologic right femur of D. niobrarensis provides evidence of hip disease in the medial Miocene rhinoceroses.
Early Records Of Some Mammals From Nebraska, J. Knox Jones Jr.
Early Records Of Some Mammals From Nebraska, J. Knox Jones Jr.
Bulletin of the University of Nebraska State Museum (1924–2023)
Ten species of Recent mammals that formerly occurred in Nebraska have been extirpated there by European man. Surprisingly few specimens of the species concerned are preserved in museum collections. Perusal of a representative segment of the historical literature pertaining to Nebraska has revealed records of occurrence of most of the extirpated species that provide a basis for estimating the former distribution of each in the State.

Geologic And Ground-Water Reconnaissance Of The Loup River Drainage Basin Nebraska, R. T. Sniegocki, R. H. Langford
Geologic And Ground-Water Reconnaissance Of The Loup River Drainage Basin Nebraska, R. T. Sniegocki, R. H. Langford
United States Geological Survey: Publications
The Loup River and its tributaries drain an area of about 15,230 square miles in central Nebraska. The upper three-fifths of the drainage basin is in the Sand Hills region of Nebraska, and the lower two-fifths is in the loess plains and hills region. An eastward-thinning wedge of semiconsolidated and unconsolidated deposits of Tertiary and Quaternary age underlies the surficial dune sand and loess. These deposits, which are recharged by infiltrating precipitation, contain a tremendous volume of water at least 400 million acre-feet and annually discharge about 1.7 million acre-feet into streams. Although wells supply nearly all the water used …

United States Department of Defense Military Intelligence
The summary on Page 5 is paraphrased as follows. This digital document is a generalized description of the Arctic Slope region -- an area covering approximately 70,000 square miles. Access to the region and the feasibility of various access routes are discussed. Location and extent of natural fuel supplies are given. Factors controlling outdoor work feasibility are summarized graphically on Page 19. A terrain analysis of each of the three major physiographic provinces of the region. Those provinces are the Arctic Coastal Plain, Arctic Foothills, and Brooks Range provinces. Geographic factors which affected cross-country movement, construction, and water supply within …
An Iron Fulgurite From Nebraska, C. M. Riley
An Iron Fulgurite From Nebraska, C. M. Riley
Bulletin of the University of Nebraska State Museum (1924–2023)
From the time of the ancients man has been impressed with the force of lightning and its effect on the rocks at the surface of the earth. It was Saussure in 1786 who first wrote a scientific account of a true fulgurite, and a wealth of literature has been written about the subject since this time. Many unusual fulgurites have been described, some of which may not truly be the result of lightning. The iron fulgurite is a strange conical object about 3 inches high composed mainly of tiny spheres and filaments of metallic iron intermixed with a small amount …

Medial Pleistocene Fossil Vertebrate Localities In Nebraska, C. Bertrand Schultz, Lloyd G. Tanner
Medial Pleistocene Fossil Vertebrate Localities In Nebraska, C. Bertrand Schultz, Lloyd G. Tanner
Bulletin of the University of Nebraska State Museum (1924–2023)
The accurate geologic dating of Pleistocene vertebrate localities which occur outside the glaciated regions has always been difficult. Several new fossil localities in Nebraska now provide data for a better understanding of the paleoecology and faunal evidence of the medial Pleistocene of the Great Plains region.
A fossil quarry, containing the remains of both vertebrates and invertebrates, has been discovered in south-central Nebraska (11/2 miles south and west of Angus in Nuckolls County). The fossils are preserved in Sappa silts in a lime concentration zone (C horizon) of a Yarmouth paleosol. The calcium carbonate appears to have been responsible for …
