From abstract: Field work leading to this report was done by the U. S. Geological Survey for the Division of Raw Materials of the U. S. Atomic Energy Commission, Nearly 24 townships were mapped in the central part of the Great Divide Basin, Sweetwater County, Wyoming, Fourteen of these townships contain outcrops of uranium-bearing coal. Thirty coal beds were mapped, but only seven of them have uranium-bearing coal reserves as defined in this report.

From introduction: The purpose of this study was to determine the magnitude of some effects of an abandoned surface coal mine on the hydrologic environment. Specific objectives were (1) to define areas of erosion and deposition; (2) to determine if the sediment yield from an undisturbed drainage basin was less than that from a drainage basin partly disturbed by mining activity; and (3) to determine if there were differences in chemical composition of hillslope materials, sediment, and pond water in the two basins.

Report discussing the U.S. Geological Survey's investigation for uraniferous coal in the central region of the Great Divide Basin of Sweetwater County, Wyoming.

The following report provides information that follows investigations of radioactivity in certain rocks found in Wyoming and South Dakota during the summer of 1945. Uranium is the principal element in this report with thorium as secondary.

The accompanying map shows the results of an airborne radioactivity survey in an area of 800 square miles in Campbell and Johnson Counties, Wyoming.

Aerial image shows the result of an airborne radioactive survey over an area of 65 square miles in the vicinity of Miller Hill, Carbon County, Wyoming with the approximate location of eleven radioactivity anomalies found. Text describes methods used and discusses the anomalies.

Aerial image shows the result of an airborne radioactive survey over an area of 154 square miles in Uinta County, Wyoming with the approximate location of one radioactivity anomaly found. Text describes methods used and discusses the anomaly.
