From introduction: The purpose of the study is to evaluate the economic possibilities of radioactive lignites and to determine the geologic factors controlling the accumulation of uranium in lignite.

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."

Abstract: An airborne radiometric survey of parts of the east flank of the Big Horn Mountains was begun on June 23, and completed on August 27, 1952. An area of approximately 250 square miles was covered, and only two anomalies were found in the entire area. Flight lines were arranged in accordance with the geology of the area, particular attention being given to formations the stratigraphic equivalents of which are known to be uranium bearing in other areas. Two additional zones of radioactivity were found by ground investigation, but assays from both the ground and the airborne discoveries showed no economic uranium deposits.

From purpose and scope: The purpose of this report is (1) to describe the flow system within the Kootenai Formation, which is the principal aquifer, and (2) to describe the interaction between the Kootenai and overlying and underlying Mesozoic aquifers.
