From abstract: An airborne radioactivity survey of a selected area in the Red Desert, Sweetwater County, Wyoming, containing outcrops of radioactive lignites and shales of known surface extent and uranium content, was flown on flight lines at three levels, respectively 250, 500, and 1,000 feet above the ground and spaced at one-quarter mile intervals. Measurements from three identical dual-channel radiation detectors were simultaneously recorded to obtain data at various distances from natural radioactive sources of known configuration. The radiation intensity measurements were fully corrected for all extraneous effects and were compiled as profiles of radiation intensity, as an isoradioactivity contour map, and as curves showing the relationship between radiation intensity and distance from the source.

From introduction: The investigations that are the subject of this report were to appraise the uranium resources of the Red Desert area, and to accumulate data concerning the geology of uranium. Knowledge of the genesis of the schroeckingerite is necessary for a clear appraisal of the deposit.

Summary: The Lost Creek schroeckingerite deposit in Sweetwater County, Wyo., has attracted attention in the past both as an occurrence of comparatively rare minerals and more recently as a possible source of uranium ore. During the summer of 1948 a newly-formed company by the name of Uranium, Inc., explored part of the deposit by bulldozer trenching and drilling. under the technical direction of the Minerals Engineering Company of Grand Junction, Colo. Examination of the significant exposures of the schroeckingerite deposit indicated that the uraniferous beds are discontinuous and that their areal distribution is erratic. The overburden has an average thickness of 2.5 feet.

"his interim report presents the grade and tonnage data collected during exploration at the Lost Creek schroeckingerite deposit, Sweetwater County, Wyoming, Between July 1951 and February 1952. Discussions of he geologic results of exploration (lithology, mineralogy, structure, origin, etc.) are not included in this report and consequently the detailed lithology and structure have been omitted from the illustrations (figs. 1-7)"

Report issued by the Bureau of Mines over an annual study of synthetic liquid fuel production. Results of the annual study are presented and discussed. This report includes maps, tables, illustrations, and photographs.

Introduction: This report is a summary of the field work at the Lost Creek schroeckingerite deposit, Sweetwater County, Wyo. from July 1 through November 22, 1952. The objectives of field work at Lost Creek during the report period were to obtain additional data for calculating tonnage and grade and to obtain additional information on the controls and localization of schroeckingerite. In order to accomplish these objectives the Survey continued the exploration by means of trenching, mapped all trench walls (scale 1:120), mapped the exploration area at scales of 1:2400 and 1:9600, and carried on an extensive sampling program.

Abstract: Preliminary reconnaissance for uranium in the Green River Basin and the Rock Springs Uplift revealed anomalous radioactivity northwest of Oregon Buttes in the Tipton tongue of the Green River formation and in the Cathedral Bluffs tongue of the Wasatch formation, and in the Tipton tongue in Red Creek Basin.

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.
