The Brule-Gering (Oligocene-Miocene) Contact In The Wildcat Ridge Area Of Western Nebraska, C. Bertrand Schultz, Charles H. Falkenbach, Carl F. Vondra Jan 1967

The Brule-Gering (Oligocene-Miocene) Contact In The Wildcat Ridge Area Of Western Nebraska, C. Bertrand Schultz, Charles H. Falkenbach, Carl F. Vondra

Bulletin of the University of Nebraska State Museum (1924–2023)

The contact between the Brule Formation (Oligocene) and the Gering Formation (Miocene) can be readily distinguished in the Wildcat Ridge area, as elsewhere in western Nebraska. At the critical fossiliferous exposures at Castle Rock in Scotts Bluff County, the contact on the south face between the two formations is defined as 129 feet above the base of the "Upper Ash" bed, which corresponds to the upper portion of Darton's (1899, PI. C, Fig. D, following p. 754) "sandy phase" in the upper part of the Brule. Certain key beds in the Gering Formation can be traced laterally from a channel …

The Ord River Catchment Regeneration Project. 1. The Nature, Extent And Causes Of Erosion In The Ord River Catchment Area, K Fitzgerald Jan 1967

The Ord River Catchment Regeneration Project. 1. The Nature, Extent And Causes Of Erosion In The Ord River Catchment Area, K Fitzgerald

Journal of the Department of Agriculture, Western Australia, Series 4

OF the 17,800 square miles of Ord River catchment area, an estimated 1,450 square miles of country is subject to varying degrees of erosion.

This lies astride the Ord River and its major tributaries, the Elvire, Negri, Stirling, Panton, Turner, Nicholson and RB rivers.

The bulk of the eroded country lies in W.A. but part projects into the Northern Territory.

The Monotypic North American Subgenus Larandrena Of Andrena (Hymenoptera: Apoidea), D. W. Ribble Jan 1967

The Monotypic North American Subgenus Larandrena Of Andrena (Hymenoptera: Apoidea), D. W. Ribble

Bulletin of the University of Nebraska State Museum (1924–2023)

Larandrena contains a single species, A. miserabilis Cresson. This small, common Andrena is found throughout most of the United States and southern Canada in the spring. The subgeneric position, nomenclature, redescription. variation, notes on the biology, parasites, range, seasonal activity and plant host records are included. A. rniserabilis is thought to be an important pollinator of fruit trees.


Citellus Kimballensis, A New Late Pliocene Ground Squirrel, Douglas C. Kent Jan 1967

Citellus Kimballensis, A New Late Pliocene Ground Squirrel, Douglas C. Kent

Bulletin of the University of Nebraska State Museum (1924–2023)

A new fossil sciurid, Citellus kimballensis, is described. This new species was found in the Kimball Formation, uppermost Ogallala (very late Pliocene) at the University of Nebraska State Museum Collecting Locality Cn-1O1, northeast of Sidney, Cheyenne County, Nebraska. Characters of the dentition and skull of C. kimballensis are compared with those of other species of the genus, and with those of Cynomys.

Surficial Geology Of The Las Vegas Quadrangle, Nevada, Charles Edgar Price Jr Jun 1966

Surficial Geology Of The Las Vegas Quadrangle, Nevada, Charles Edgar Price Jr

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Las Vegas 15-minute quadrangle, located in the south part of the state of Nevada, includes about 240 square miles in and around the city of Las Vegas; it is in the basin and range province. The quadrangle includes a broad valley floor that was once a lake bottom, a bordering area of badlands and rolling hills developed in Tertiary and Quaternary deposits, an outer marginal area of alluvial fans, and the surrounding mountains.

The mountains constitute about three per cent of the total land surface and are composed of rock ranging in are from Precambrian to Tertiary. The remainder …

Revision Of The Classification Of The Pleistocene Deposits Of Nebraska, E. C. Reed, V. H. Dreeszen Jan 1965

Revision Of The Classification Of The Pleistocene Deposits Of Nebraska, E. C. Reed, V. H. Dreeszen

Conservation and Survey Division: Faculty and Staff Publications

The first major contribution of the Conservation and Survey Division to Pleistocene stratigraphy was that of A. L. Lugn (1935) who established a classification of the periglacial deposits of the state and related these deposits to the glacial stages. G. E. Condra and E. C. Reed (1950) used information aquired during the 1935-1950 period in making important revisions to Lugn's classifications. This report was a further revision based on studies made from 1950 to publication date (1965).
