Aerial image shows the result of an airborne radioactive survey over an area of 700 square miles in Sweetwater County, Wyoming with the approximate location of three radioactivity anomalies found. Text describes methods used and discusses the anomalies.

A generalized geologic map shows the locations of the uranium mines and some of the many occurrences and prospects in the Gas Hills district. Included also are recently-mapped structural features and results of analyses of uranium in water.

From abstract: Uranium deposits and radioactivity anomalies have been found in the eastern half of the area underlain by the Browns Park formation in northwestern Colorado, south-central Wyoming, and northeastern Utah. The deposits are in eolian, lacustrine, and fluvial sandstones, tuffaceous sandstones, and limestones all of which were deposited on two converging pediments during Miocene time. At least one eastern and one western facies of lacustrine and fluvial sedimentary rocks are separated by a belt of eolian sandstones. The faces may be distinguished in the field and by petrographic and heavy-mineral studies in the laboratory.

The following report covers a reconnaissance for uranium-bearing carbonaceous rocks that was made during the 1952 field season in 23 areas in Colorado, Utah, Idaho, and Wyoming. This report discusses uranium samples discovered withing these locations, however it was determined that none of the deposits discovered have commercial possibilities.

Report discussing a reconnaissance for uranium-bearing carbonaceous rocks during the 1952 field season in 23 areas in Colorado, Utah, Idaho, and Wyoming. From Abstract: "Uranium in small amounts occurs in several of the areas examined, but no deposits were found that might have commercial possibilities."

Report discussing an investigation of copper deposits in sandstone that were believed to be possibly uraniferous, and uraniferous asphaltite deposits.

The following report discusses the results from studies made during a program of geological mapping and exploratory core drilling that was carried out from 1951 to 1953 by the U.S. Geological Survey on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission to determine the areal distribution, thickness, and uranium content of coal in the eastern part of the Red Desert area, Sweetwater County, Wyoming.

A report regarding uranium-bearing coal in the eastern part of the great divide basin, in sweetwater county, Wyoming. This report concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.
