From abstract: This two-part report provides an essentially complete listing of radioactive occurrences in Colorado, with a comprehensive bibliography and bibliographic cross-indexes.

This report is a preliminary evaluation of the uranium resources of the Brushy Basin Member of the Morrison Formation of Late Jurassic age in southwestern Colorado and southeastern Utah. The project, which began July 1, 1976, and was completed October 1, 1976, was carried out by the Bendix Field Engineering Corporation (BFEC) for the Grand Junction Office of the U.S. Energy Research and Development Administration (ERDA).

"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).

Supplementary data containing locations of uranium deposits in the Brushy Basin project area, Utah and Colorado.

Report and geological survey. This report examines the ground water within the Wet Mountain Valley, Colorado. It includes maps of the area.

This report analyses the water quality of Lake George in Colorado and the four aquifers that feed into it. It includes maps and tables.

This report examines the region of the Piceance Creek basin in Colorado so that the United States Bureau of Mines may develop plans for an underground oil-shale research facility in the center of the basin. It includes maps, charts, and graphs.

Report and geological survey. This report uses maps that depict climatic factors to make a flood-frequency model. It includes numerous maps, tables, and other figures.

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 Greeley quadrangle in Colorado.

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.

From abstract: "This study used Landsat images and small-scale color and color-infrared photographs for selected geologic, hydrologic, and land-use applications within the Yampa River Basin" in Colorado and Wyoming. It includes maps, tables, and a glossary.

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

This report presents a "digital model used to simulate ground-water flow in the aquifer system in a basin drained by Piceance and Yellow Creeks, Colorado." It includes maps, diagrams, and tables.
