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

From introduction: This report describes work done in the Denver and Greeley National Topographic Map Series (NTMS) quadrangles (1:250 000 scale) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

Letter from WASP Mickey Brown to a friend named Betty discussing pictures from the reunion in Colorado Springs, flying, recent correspondence, and other minor topics.

Newspaper clipping from the Colorado Springs Gazette-Telegraph discussing the recent recognition of the WASP as military veterans due to legislation sponsored by Barry Goldwater, with a picture of Millicent Young. On the back are excerpts about the Palestinian and Lebanese conflicts.

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.

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).

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

Electric power generation by conventional Rankine cycle heat engines with heat supplied by line-focus solar collectors was investigated. The objectives of the study were: (1) determine which of four types of line-focus solar collectors coupled with turbine-generators of conventional design has the potential to produce low-cost electric power with thermal energy in 100 to 300/sup 0/C range; (2) develop performance and cost relationships for organic Rankine cycle engines for power generation capacities from 3 MW/sub e/ to 300 MW/sub e/; (3) develop conceptual storage units for organic fluid systems. Evaluation procedures and study results and conclusion are presented and discussed in detail. (WHK)

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.

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.

Average record data listings taken during aerial gamma-ray and magnetic surveys of 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.

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.

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

From introduction: This report describes work done in the Trinidad, Colorado, National Topographic Map Series (NTMS) quadrangle (US Geological Survey, 1955) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

Fly ash derived from coal combustion contains predominantly spherical particles which consist of an insoluble aluminosilicate glass containing several mineral impurities. An outer layer, 50 to 300 A thick, is rich in many potentially toxic trace elements in the form of simple and complex sulfates. This layer, which is soluble in water, contains essentially all of the particulate sulfur present in fly ash in the form of sulfate. The actual mechanism(s) of formation of particulate sulfate salts are ill-defined but probably involve adsorption of condensation of gaseous sulfur species onto fly ash surfaces within the power plant stack system.

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

From introduction: This report describes work done in the Sterling, Colorado, National Topographic Map Series (NTMS) quadrangle (1:250 000 scale) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

From summary: This data release presents analytical results obtained for a pilot study being done in portions of the Sterling and Greeley, Colorado, National Topographic Map Series (NTMS) quadrangles (Fig. 1) by the University of Colorado under contract to the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).
