This report provides the results of analyses of the airborne gamma radiation and total magnetic field survey flown for the Valentine quadrangle in Nebraska and South Dakota.

Final report analyzing aerial gamma ray and magnetic data in the Nebraska City quadrangle, including a detailed geologic summary, interpretation report, reduced scale copies of all maps and profiles, histograms, and statistical tables for the quadrangle.

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

From Purpose and Scope of Study: "The Torrington 1ºx2º Quadrangle in southeastern Wyoming and a small area of westernmost Nebraska was evaluated to determine areas favorable for the occurrence of uranium deposits. Geologic environments (areally or stratigraphically restricted parts of a geologic unit) were placed in categories of favorable, unfavorable, or unevaluated."

From Introduction: "The Hot Springs Quadrangle covers an area of approximately 18,500 km2 and is in southwestern South Dakota and northwestern Nebraska between latitudes 43º to 44ºN. and longitudes 102º to 104ºW. (Fig. 1). The quadrangle was evaluated at the surface and in the subsurface to a depth of 1500 m to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits."

"Results of a reconnaissance geochemical survey are reported for the Sioux City Quadrangle, Nebraska; Iowa; South Dakota. Statistical data and areal distributions for uranium and uranium-related variables are presented for 119 groundwater and 542 stream sediment samples. Also included is a brief discussion on location and geologic setting."

"Results of a reconnaissance geochemical survey of the Scottsbluff Quadrangle are reported. Field and laboratory data are presented for 567 groundwater and 402 stream sediment samples. statistical distributions and symbol plots for uranium and possible uranium-related variables are enclosed. A generalized geologic map and a 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."

Final report documenting a high-sensitivity airborne gamma radiation and magnetic field survey of the McCook National Topographic Map segment (NK 14-10 quadrangle) including a description of the program and results with the flight line profile data and statistical analysis results.

This report presents field and laboratory data for 567 groundwater samples and 560 stream sediment samples collected from the Fremont quadrangle in Nebraska and Iowa.

"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)

"Results of a reconnaissance geochemical survey of the Broken Bow Quadrangle, Nebraska are reported. Statistical data and aerial distributions for uranium-related variables are presented for 578 groundwater and 442 stream sediment samples. Also included is a brief discussion on location and geology." (from Abstract)

Final report of the airborne gamma ray and total magnetic field survey for the Sterling quadrangle, Colorado-Nebraska-Kansas. Sections I through IV of this report present information and results associated with this specific survey. Section V gives the data acquisition and the processing procedures.
