Report issued by the U.S. Bureau of Mines on the characteristics of oil obtained from the Tensleep Sandstone Reservoir. The samples collected are analyzed for physical characteristics and presented in tables and graphs. The report also includes a map.

From introduction: The reconnaissance was made during the summer of 1951 by two field parties: (1) a reconnaissance in parts of Oklahoma, Texas, New Mexico, and Arizona by Russell Gibson, and (2) Geological Survey reconnaissance in parts of New Mexico,.Colorado, Utah, Idaho, and Wyoming (by the writers), the results of which are summarized in this report.

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.
