From introduction: The overall purpose of this study were twofold: (1) To determine where greatest yielding wells at shallowest depths would produce water of suitable quality for municipal and industrial supplies; and (2) to determine regional effects of additional water development on the hydrologic system.

Uranium resources of the Newcastle 1°x2° Quadrangle, Wyoming and South Dakota were evaluated to a depth of 1,500 m (5000 ft) using available surface and subsurface geologic information. Many of the uranium occurrences reported in the literature and in reports of the U.S. Atomic Energy Commission were located, sampled and described. Areas of anomalous radioactivity, interpreted from an aerial radiometric survey, were outlined. Areas favorable for uranium deposits in the subsurface were evaluated using gamma-ray logs. Based on surface and subsurface data, two areas have been delineated which are underlain by rocks deemed favorable as hosts for uranium deposits. One of these is underlain by rocks that contain fluvial arkosic facies in the Wasatch and Fort Union Formations of Tertiary age; the other is underlain by rocks containing fluvial quartzose sandstone facies of the Inyan Kara Group of Early Cretaceous age. Unfavorable environments characterize all rock units of Tertiary age above the Wasatch Formation, all rock units of Cretaceous age above the Inyan Kara Group, and most rock units of Mesozoic and Paleozoic age below the Inyan Kara Group. Unfavorable environments characterize all rock units of Cretaceous age above the Inyan Kara Group, and all rock units of Mesozoic and …

"Results of a reconnaissance geochemical survey of the O'neill Quadrangle are reported. Field and laboratory data are presented for 23 groundwater and 292 stream sediment samples. Statistical distributions and symbol plots for uranium and possible uranium-related variables are enclosed. A generalized geologic map and producing horizon map for the survey area are provided. Pertinent geologic factors that may be of significance in evaluating the potential for uranium mineralization are briefly discussed." (from Abstract)

From Purpose and Scope: "The Gillette 1º x 2º Quadrangle, Wyoming, and South Dakota was evaluated to find volumes of rock considered favorable for uranium deposits and which could contain at least at 100 mt tons U3O8 with an average grade of 0.01 percent U3O8 or more. All geologic environments to a depth of 1,500 m (5,000 ft) evaluated through the use of surface investigations and subsurface information."

Final report regarding the National Logging Program for the National Uranium Resource Evaluation

From abstract: "Laboratory studies of uraniferous coal were started in connection with explorational core drilling in 1951. The cores were described and used for coal analyses, for determinations of uranium and other mineral elements, and for microscopical investigations. Results of microscopical studies are feature in this report."
