Reconnaissance for Trace Elements in North Dakota and Eastern Montana

Description: From abstract: A reconnaissance for sources of radioactive material in North Dakota and eastern Montana was made in 1948. This reconnaissance was followed by a more detailed survey of parts of Golden Valley and Slope counties, southwestern North Dakota, in June 1949. The radioactivity of representative sections of all formations known to be exposed in the area and of three manganiferous spring deposits was determined with portable Geiger-Mueller counters. At 86 localities 82 samples were taken of these formations and also of 10 ground and surface waters.

The Moraines of the Missouri Coteau, and their Attendant Deposits

Description: 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 and the series of drift deposits, covering an area with successive layers of till in a manner which might be compared to a nest of spoons of assorted sizes, the smaller lying inside the larger. Of these spoonshaped deposits, the moraines form the outer rims. 3.) As the moraines are the most conspicuous features of the drift formations, we may take them as the basis for dividing the subject. Not only are they the most conspicuous features of the topography, but they mark culminations of glacial activity. We therefore propose reviewing our subject under the following heads: I.) The First ...

Water Resources of the Rattlesnake Butte Area, a Site of Potential Lignite Mining in West-Central North Dakota

Description: From objectives and scope: The objectives of the study were to: (1) Determine the geographic extent of the minable lignite beds and identify aquifers down to a depth of about 400 feet beneath the lower minable lignite; (2) assess the ground-water flow regime in all aquifers found; (3) evaluate the flow characteristics of the two streams draining the study area; and (5) qualitatively assess the impacts mining might have on the hydrologic system.

An Assessment of the Collection and Analysis of Hydrologic Data by Private Contractors for the U.S. Geological Survey

Description: From abstract: During fiscal years 1978 through 1981, the U.S. Geological Survey contracted for the acquisition and analysis of hydrologic data from 104 surface water stations, 26 ground water stations, and 15 precipitation gages as well as for several hundred miscellaneous surface water measurements of flow and water quality. The work was performed in Montana, North Dakota, Wyoming, Utah, New Mexico, and Oklahoma, terminating at the end of the fiscal year 1981. This report is an assessment of this contracting effort from the standpoint of cost and of quality control measures employed to ensure an acceptable product.

Hydrology of the Wibaux-Beach Lignite Deposit Area, Eastern Montana and Western North Dakota

Description: From objectives and scope: This study was undertaken in response to U.S. Bureau of Land Management concerns for the water resources of the Wibaux-Beach area in the event of lignite mining. The objectives of the study were to: (1) Define the stratigraphic sequence within a few hundred feet above and below the minable lignite; (2) define the premining hydrologic and geochemical regime of the Wibaux-Beach deposit area; and (3) describe some of the hydrologic implications of the strip-mining process. A fourth objective, the establishment of historical data base with which to access any modifications to the system attributable to future mining, was accomplished as a byproduct of the other three.

Evaluation of the Effects of Lake Audubon on Ground- and Surface-Water Levels in the Lake Nettie Area, Eastern Mclean County, North Dakota

Description: Purpose and scope: The purpose of this investigation is to describe changes in the ground-water levels and levels of surface-water bodies and to ascertain whether those changes can be ascribed to the raising of the level of Lake Audubon, or to the subsequent filling of the McClusky Canal, or both. The changes will be determined by analysis of water-level records obtained from observation wells.

Description: Abstract: This report lists the machine-readable data files developed for the Madison Limestone and Northern Great Plains Regional Aquifer System Analysis (RASA) projects that are stored on magnetic tape and available from the U.S. Geological Survey. Record format, file content, and size are given for: (1) Drill-stem-test data for Paleozoic and Mesozoic formations; (2) geologic data from the Madison Limestone project; (3) data sets used in the regional simulation model; (4) hydraulic-head data for the Lower and Upper Cretaceous aquifers; and (5) geologic data for Mesozoic formations of the Northern Great Plains.

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

Description: 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.

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

Description: 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.

Strippable lignite Deposits, Slope and Bowman Counties, North Dakota

Description: From abstract: Slope and Bowman Counties, N. Dak., include an area of about 2,450 square miles in the southeastern part of the Fort Union coal region of North Dakota, South Dakota, and Montana. In anticipation of a future increase in the demand for the low-rank coal of this region as a fuel for electric power plants and as a raw material for various chemical synthesizing processes, Slope and Bowman Counties were investigated for deposits of lignite that could be mined by large scale strip mining methods. All the lignite beds of economic importance in this area are in the Fort Union formation, particularly in the Tongue River member. The beds are nearly horizontal, dipping about 25 to 50 feet per mile north and northeast from the Cedar Creek anticline in the southwest corner of the area.
