Results of Core Drilling of Uranium-Bearing Lignite Deposits in Harding and Perkins Counties, South Dakota, and Bowman County, North Dakota (open access)

Results of Core Drilling of Uranium-Bearing Lignite Deposits in Harding and Perkins Counties, South Dakota, and Bowman County, North Dakota

Purpose: The main objective of the Dakota core drilling program was to determine reserves of uraniferous lignite based on chemical uranium and spectrographic determinations from unweathered samples, particularly from those areas where surface sampling of the beds during the previous field season indicated that significant deposits of uranium-bearing lignite might be present. A secondary objective was to obtain fresh samples and to measure the radioactivity of the overlying Oligocene White River and Miocene Arikaree formations from which the uranium in lignite is believed to have been derived.

The Moraines of the Missouri Coteau, and their Attendant Deposits (open access)

The Moraines of the Missouri Coteau, and their Attendant Deposits

Introduction: It seems important that several general facts should be stated for the full understanding of terms used and allusions made in this report. The field considered is the region lying between the Missouri and James rivers, and between the latitudes of Jamestown, N. Dak., and Huron, S. Dak. 1. As has been stated in papers published by Chamberlin, Upham, myself, and others, several more or less distinct moraines have been observed in the Mississippi Valley. It has been found convenient to distinguish the outermost three by special names. President Chamberlin has named them, beginning with the outermost, Altamont, Gary, and Antelope moraines, from localities south of Big Stone Lake, and these names have been quite generally adopted. Upham and others have named them the First, Second, and Third, and as the outermost two are the more prominent, they have also been called the Outer and Inner moraines. Each of these, especially the First and Second, has subordinate divisions, which mark the borders of the different lobes into which the margin of the ice sheet was often divided. 2.) It is assumed that the reader is familiar with the generally recognized features of drift formations, such as the undulating topography …

Preliminary Digital Model of Ground-Water Flow in the Madison Group, Powder River Basin and Adjacent Areas, Wyoming, Montana, South Dakota, North Dakota, and Nebraska (open access)

Preliminary Digital Model of Ground-Water Flow in the Madison Group, Powder River Basin and Adjacent Areas, Wyoming, Montana, South Dakota, North Dakota, and Nebraska

Abstract: A digital simulation model was used to analyze regional ground-water flow in the Madison Group aquifer in the Powder River Basin and adjacent areas. Most recharge to the aquifer originates in or near the outcrop areas of the Madison in the Bighorn Mountains and Black Hills , and most discharge occurs through springs and wells. Results from the model calculations indicate that the total flow through the aquifer in the modeled areas was approximately 200 cubic feet per second (5.7 cubic metres per second). The aquifer can probably sustain increased ground-water withdrawals probably would significantly lower the potentiometric surface in the Madison aquifer in a large part of the basin. The digital model could better predict the effects of withdrawals if more accurate estimates of the storage coefficient, transmissivity, and leakance could be obtained.
