Implications Of Photogeologic Linears In The South Long Lake Area, Alpena And Presque Isle Counties, Michigan, Richard E. Kimmel

Masters Theses

There are numerous linear features in Alpena and Presque Isle Counties, Michigan, which are generally visible on aerial photographs. These photolinears trend in two general directions, northeast-southwest and northwest-southeast. These two sets are perpendicular to each other, and represent vector means of two fracture sets.

The development of the photolinears began in Early Devonian. Throughout its history, ground water flowed along underground channels connecting fracture intersections. This underground drainage network is responsible for many of the photolinears. Some of the photolinears can be attributed tb Early Devonian ground water activity and subsequent collapse of the Salina Salt basin, and some …

The Pierre-Niobrara Unconformity In Western Nebraska, Harold M. Degraw

Conservation and Survey Division: Faculty and Staff Publications

The Pierre-Niobrara unconformity, one of several significant unconformities in the Cretaceous System of the Western Interior region, has not generally been recognized. Detailed correlation of electric logs of a large number of wells in western Nebraska provides evidence of its existence. Isopach maps of the beds occupying three identifiable stratigraphic intervals - a redefined Niobrara Formation, an unnamed uppermost Niobrara unit, and an unnamed basal Pierre unit, which includes the Ardmore Bentonite - provide recognizable geologic patterns that permit reconstruction of the stages of development of the unconformity. The upper part of the Niobrara Formation has been truncated in several …

The Geology Of The Pittsburg Landing Area, Snake River Canyon, Oregon-Idaho, David L. White

All-Inclusive List of Electronic Theses and Dissertations

The major purpose of the study was to map, describe, and correlate the pre-Tertiary rocks. Accessible and excellent exposures at Pittsburg Landing enabled the writer to make a somewhat detailed study of the stratigraphy. The thesis area also offered an opportunity to study in a reconnaissance manner, the Tertiary Columbia River Basalt as described by Waters, and more recently y Ozier.

A New Species Of Menoceras From The Marsland Formation Of Nebraska, Lloyd G. Tanner

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

Further study indicates that the Menoceras remains collected from the "Bridgeport Quarries" (lower port:on or the Marsland Formation, Middle Miocene, of the Hemingford Group) are of a new species.

In 1962, these dicerathere remains were considered to be a geologic variety of Diceratherium niobrarensis (Stecher, Schultz, and Tanner). However, later (Tanner, 1969) a generic distinction was revived, separating the Menoceras Troxell from Diceratherium Marsh. Diceretherium niobrarensis was then placed in synonymy with Menoceras arikarense (Barbour).

The new species is an intermediate between Menoceras arikarense (Barbour) from the Harrison Formation and Menoceras marslandensis Tanner, from the upper portion of the Marsland …

Two Lynx-Like Cats From The Pliocene And Pleistocene, C. Bertrand Schultz, Larry D. Martin

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

A new species (Lynx stouti) of small felid is described from the lower Pliocene of Colorado. This form has several characters in common with the modern Lynx and may be ancestral to that genus. A new subspecies of Lynx issiodorensis Croizet and Jobert is described as L. i. kurteni from the Mullen Assemblage, Cherry County, Nebraska. The relationships of this form to other lynxes are discussed along with the paleo-distribution of the genus.

The classification of the felinae has always been somewhat controversial, especially at the generic level. One fairly homogenous group of cats which has been separated …

Phyletic Trends In Certain Lineages Of Quaternary Mammals, C. Bertrand Schultz, Lloyd G. Tanner, Lary D. Martin

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

Evolutionary trends in certain carnivores, rodents, bovids, and proboscideans are examined. Chronoclines are demonstrated for muskrats, beavers, mammoths, and bison. The Pliocene-Pleistocene boundary and Quaternary climatic fluctuations are also discussed.

The University of Nebraska State Museum contains a large stratigraphically controlled collection of Pleistocene animals. This collection provides a unique opportunity for the study of phyletic trends in certain lineages of mammals. Although a few phylogenetic lineages have been proposed (Schultz and Frankforter, 1946; Hibbard, et al., 1965), this has not been done for the vast majority of Pleistocene mammals. However, there is much more data available than this would …

The Microtine Rodents Of The Mullen Assemblage From The Pleistocene Of North Central Nebraska, Larry D. Martin

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

The University of Nebraska State Museum has had an active collecting program in Hooker and Cherry counties, Nebraska, since the 1930's. The following University of Nebraska State Museum collecting localities have been extensively excavated: Cr-10, Cr-102, Cr-11, Ho-101, Ho-102, and Ho-103. These localities have produced a large vertebrate fauna described by Jakway as the Mullen Local Fauna which he considered for the most part to be Early lllinoian. Further study of this local fauna now demonstrates that assemblage does include Early as well as Middle Pleistocene animals. The purpose of this paper is to report on the evidence regarding the …

Interbasin Water Transfers And Groundwater Regulation In Nebraska, D. D. Axthelm, V. H. Dreeszen, C. A. Lewis

Conservation and Survey Division: Faculty and Staff Publications

On November 29, 1971, the Hamilton County Ground Water Con·­servation District sponsored a meeting on groundwater management and regulation. The meeting was held at Aurora, Nebraska, and was designed for irrigators from groundwater conservation dis­tricts and county irrigation associations. Various men from state and federal agencies spoke about a variety of problems that a.re related to groundwater management. Two of the talks that were presented at the meeting are reproduced here, as is a discussion of the rules and regulations that relate to the use of groundwater in the state of Nebraska.
