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 introduction: Geologic mapping was done in the Pumpkin Buttes area, Johnson and Campbell Counties, Wyoming, during the summer of 1952 on behalf of the Atomic Energy Commission. The objectives of the work were: to find uranium deposits, to study their distribution, habit, and occurrence, and to use such knowledge as guides in outlining areas favorable for mineralization.

Report discussing the investigation of uranium minerals, which were discovered in the Poison Basin area, Carbon County, Wyoming, on October 15, 1953. Information regarding the geographic setting, geologic setting, stratigraphy of the area, uranium occurrences of the area, origin of the uranium, and significance of the area 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.

Report containing abstracts of some stratigraphic sections of the Permian Phosphoria formation in western Wyoming.

The following document is a compilation of technical reports concerning the technical aspects of the Wagon Wheel Project studies, studies that analyze underground nuclear explosions.

From abstract: The High Plains Regional Aquifer System Analysis study has developed a regional water-resources (and related) data storage and retrieval system to organize and preserve areal interpretive data. The system is general and can easily be adapted for other studies. This report documents the High Plains data base as well as the general system that is independent of the High Plains area.

The data collected in this report was recorded after a high sensitivity airborne radiometric and magnetic survey was conducted over the Rock Springs, Rawlins, and Cheyenne quadrangles in Wyoming, and the Greeley quadrangle in Colorado.

A preliminary map showing the lithology of parts of the Powder River Basin, Wyoming.

This map shows geologic formations of sandstone, shale, siltstone, mudstone, and coal, carbonaceous markers, coal seams, creeks and rivers, draws and gulches, mountains, buttes, and numbered locations of uranium test holes.

This report tracks and analyses the annual sediment yield for the Yampa River basin in Colorado and Wyoming. It includes maps, tables, and graphs.

Introduction: The alluvial deposits form the principal aquifer in the Owl Creek Valley and the source of water to many stock and domestic wells and to a few irrigation wells. In 1975, the U.S. Geological Survey, in cooperation with the Wyoming State Engineer, began an investigation of the hydrology and geology, including the geomorphology, of Owl Creek Valley (fig. 1) to determine possible favorable areas for obtaining ground water of adequate chemical quality for irrigation and other uses. The part of Owl Creek basin investigated is downstream from Anchor Reservoir and includes North Fork, South Fork, and the mainstem of Owl Creek (pi. 1). However, the area downstream from Embar Ranch (pi. 1) was emphasized during the study.

The following report provides results and studies that were made in the Rawlins quadrangle, Wyoming with the purpose of identifying the granitic rocks having higher normal concentrations of uranium, as possible sources of large, low grade uranium ore.

Report issued by the U.S. Bureau of Mines discussing bituminous coal and lignite seams found in the United States. The thickness of seams from several U.S. states is compared, as well as the mining methods employed. This report includes maps, tables, and illustrations.
