From introduction: This study is a comprehensive investigation of altered sandstone associated with uranium deposits near Pumpkin Buttes in the Powder River Basin of Wyoming, and the detection of such alteration using remote sensing technology. The purpose of this study is two-fold: 1) to develop video image processing techniques that will preferentially enhance areas of alteration associated with uranium deposits and enable mapping of these areas, and 2) to investigate the spectral, geochemical, and mineralogical characteristics of altered areas which make them detectable on remote sensor data. Once these video processing techniques have been defined, they may be applied as exploration tools to new areas with similar surface and geological environments. In this way, remote sensing can serve as a valuable tool for uranium exploration.

From abstract: From September 15 to September 28, 1978, geoMetrics, Inc., collected 4320 line miles of high sensitivity airborne radiometric and magnetic data in Wyoming and Nebraska within two 1° x 2° NTMS quadrangles (Torrington and Casper).

During the spring and summer of 1976, 2144 water and water transported sediment samples were collected from 1685 locations spread over an approximate 21 000 km area of the northern end of the Powder River Basin in northeast Wyoming.

From introduction: This is a progress report on regional stratigraphic and paleontologic studies of the Upper Cretaceous Montana Group and equivalent rocks in the northern part of the western interior of the United States. It presents preliminary data on the positions of strandlines during a 14-m.y. (million year) span of the Late Cretaceous as well as our interpretations of the geologic history of this period.

This report presents uranium and other elemental data as part of the National Uranium Resource Evaluation which is designed to provide improved estimates of the availability and economics of nuclear fuel resources and to make available to industry information for use in the development and production of uranium resources.

Report issued by the Bureau of Mines over the oil yields at the Green River. The average oil yields from the area are discussed. This report includes tables, and illustrations.

Report issued by the Bureau of Mines discussing the geology and oil-yield of the Green River in the Washakie Basin, Wyoming. Evaluations of the geology and oil-shale resources of the area are presented. This report includes tables, maps, illustrations, and photographs.

"This report summarizes published geotechnical properties of raw and retorted oil shales from the Green River Formation. Basic physical properties including gradation, specific gravity and Atterberg limits and engineering properties including compaction, permeability, settlement, soundness, and strength are summarized and discussed. Where appropriate, conclusions are drawn about the suitability of retorted oil shales as a geotechnical construction material. Appendix A discusses three retorting processes used to extract oil from oil shale" (abstract, para. 2-3).

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.

Report describing the analysis of water and sediment samples taken from the Cheyenne quadrangle in Wyoming to determine if they contained uranium. Several areas were identified for further study, based on initial analyses.

From introduction: This report describes work done in the Rawlins, Wyoming, National Topographic Map Series (NTMS) quadrangle (US Geological Survey, 1968) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

The following report follows a mineral survey of the Glacier Primitive Area and adjoining area in Wyoming, that was made in 1968 and 1969.

The following report is an evaluation of the mineral potential of the Laramie Peak area, Wyoming.

From purpose and scope: The purposes of this investigation are (1) to define the ground-water system in the Arikaree Formation, (2) to determine the hydrologic cause-and-effect relationships resulting from the current ground-water development, and (3) to provide a means of indicating the hydrologic effect of future ground-water development.

Abstract: Dissolved-solids concentrations and loads can be estimated from streamflow records using a regression model derived from chemical analyses of monthly samples. The model takes seasonal effects into account by the inclusion of simple-harmonic time functions. Monthly mean dissolved-solids loads simulated for a 6-year period at U.S. Geological Survey water-quality stations in the Green River Basin of Wyoming agree closely with corresponding loads estimated from daily specific-conductance records. In a demonstration of uses of the model, an average gain of 114,000 tons of dissolved solids per year was estimated for 6-year period in a 70-mile reach of the Green River from Fontemelle Reservoir to the town of Green River, including the lower 30-mile reach of the Big Sandy River.

From introduction: The purpose of the study was to describe the differences between ponds that developed within and abandoned mine site and in control ponds not affected by mining.

This report presents the findings of the analyses made for a fifty-eight mile stretch along the Yampa River in Colorado. It contains maps, graphs, and tables.

From abstract: This report presents a method for estimating temperatures of streams in the Green Water Basin, Wyoming.

Abstract: The alluvial aquifer along the Greybull River consists principally of the Greybull terrace deposits and the flood-plain alluvium but also includes the Burlington terrace deposits and the flood-plain alluvium but also includes the Burlington terrace deposits east of Burlington, the McKinnie terrace, and the younger, generally undissected alluvial-fan deposits. Well-log data and 18 surface-resistivity measurements at four localities indicate that the thickness of the alluvial aquifer is as much as 60 feet thick only near Burlington and Otto. The most favorable area for development of ground water from the alluvial aquifer is near Burlington and Otto where relatively large amounts of water can be obtained from the Greybull terrace deposits and the flood-plain alluvium. Elsewhere, the deposits of the alluvial aquifer yield only small amounts of water to wells.

From abstract: "A description of aquatic organisms and biological communities is presented fro Salt Wells Creek, a plains stream in the Green River basin. The description includes seasonal population fluctuations of benthic organisms and algae, the food pyramid, and nutrient relations between various types of plants and animals. The algae and stream invertebrates were studied to determine baseline data and biological indicators of water quality." It includes maps, photographs, diagrams, and a glossary.

This report examines and describes the geohydrologic status of the Albin and La Grange areas, specifically focusing on the use of irrigation wells to access ground water. Includes maps and illustrations.

This report is the second volume in a series of reports documenting airborne radiometric and magnetic survey results for the Rockies/Laramie Range project. This volume contains data maps on the Rock Springs quadrangle in Wyoming.
