Abstract: A radiometric reconnaissance, using a portable beta-gamma survey meter, of some geologic formations ranging in age from Cambrian to Cretaceous, and springs in southeastern Idaho, western Wyoming, and northern Utah, has shown that none of them are sufficiently radioactive to warrant further examination of them in the area.

From introduction: This report on the geology of the Powder River Basin is one of a series of reports by the Geological Survey on sedimentary basins in the United States.

The following report covers the Petrographic study of Early Cretaceous age sandstone beds in the Fall River formation and the Fuson-Lakota formations, as well as Late Jurassic age beds in the underlying Unkpapa and Morrison formations along the western side of the Black Hills.

A report regarding petrographic study of sandstone of the Inyan Kara group and associated rocks in the Black hills, Wyoming and South Dakota

From abstract: The uranium deposits in the Carlile quadrangle, southwestern Crook County, Wyo., are in relatively flat-lying sandstone beds in the lower part of the Inyan Kara group of Early Cretaceous age. The Carlile mine has the largest deposit in the quadrangle; the ore minerals are carnotite and tyuyamunite associated with carbonaceous material in a sandstone lens.

The following report presents a generalized description of the uranium deposits discovered in the northern Black Hills.

From introduction: This report details the reconnaissance for uraniferous lignites in North Dakota, South Dakota, Montana, and Wyoming during 1948 and 1949.

The following report covers a reconnaissance for new discoveries of radioactive lignite deposits in the Green River Basin and Uinta Basin of Wyoming and Utah where similar discoveries to previous studies in North Dakota, South Dakota, Montana, and Wyoming were made. Additionally, there were new prospects examined, as well as reconnaissance for uranium deposits.

Report discussing the reconnaissance for radioactive uraniferous rocks in parts of Colorado, Wyoming, and Utah. Regional geology of each area, results of regional reconnaissance, and miscellaneous prospects are included.

Report discussing a geological study performed to find uraniferous lignites in North Dakota, Eastern Montana, north-central Wyoming, and northwestern South Dakota. "Deposits of uraniferous lignites were discovered at Blue Buttes, eastern Montana; and at North Cave Hills, South Cave Hills, and at Slim Buttes in northwestern South Dakota."

Report discussing the investigation of the mineralogy and geochemistry of some subbituminous uraniferous coal from the Red Desert area of Sweetwater County, Wyoming. Data and discussion from the mineralogic and geochemical studies, Fischer retort assays of a coal sample, and summary and conclusions are included.

Report discussing investigation of the extraction of uranium from subbituminous coal collected from the Red Desert, Wyoming. Information on the samples of coal used, experimental data, and summary and conclusions of findings are included.

The following report describes the study of the hydrous uranium-molybdenum mineral umohoite discovered in the Lucky Mc mine, Wyoming.

Report discussing investigations seeking uranium in deposits of black shale around the geographical areas of the Western States

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.

Several geologic maps of deposits in Sweetwater County, Wyoming.

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

Report discussing the uranium deposits located in the Miller Hill area of Carbon County, Wyoming. A stratigraphic description of the area is also given.

Preliminary report discussing uranium that was found in the basal limestone of the Sundance formation of late Jurassic age on the east flank of the Bighorn Mountains in Johnson County, Wyoming. The report provides information regarding geographic setting, geologic setting, stratigraphy, uranium occurrence localities, and origin of uranium in the Mayoworth area.

Report discussing a preliminary study of limonite sourced from nine localities of different types through Colorado, Utah and Wyoming, in the spring and fall of 1953. This study aimed to establish criteria for differentiating uranium- and thorium-related limonite and limonite not related to uranium or thorium. The report is divided by descriptions of each locality.

A report regarding a preliminary study of radioactive limonite localities in Colorado, Utah, and Wyoming. Concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic energy Commission.

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.
