From abstract: Five mines in north-central Clear Creek County- Golden Calf, Gomer, Martha E., Golden Glen, and Diamond Mountain--have high anomalous radioactivity and are considered potential sources of uranium.

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 abstract: Six diamond-core holes totaling 2, 201 feet were drilled by the U. S. Bureau of Mines under contract to the U. S. Atomic Energy Commission at the Old Leyden coal mine, Jefferson County, Colo. The holes were spotted on the basis of geologic mapping by the U. S. Geological survey and were drilled to explore the lateral and downward extent of a uranium-bearing coal and the associated carnotite deposits in the adjacent sandstone. The data obtained from the diamond-core holes helped to explain the geology and structural control of the deposit. The uranium is most abundant in a coal bed that in places has been brecciated by shearing, and then altered to a hard, dense, and silicified rock. The uraniferous coal is in the nearly vertical beds of the Laramie formation of Upper Cretaceous age,

Abstract: The Treasure Hill area consists of eight mining-lode claims in secs. 10 and 15, T. 9 N., R. 70 W., Larimer County, Colo. All of the workings were examined and samples were taken from most of them. The results of the examination indicate that there is little or no detectable radioactivity in the schist and granite of the area.

From introduction: The primary objective of these studies is to determine the content and distribution of uranium areally and stratigraphically in the Sharon Springs member of the Pierre shale of Late Cretaceous age.

This is a geological map of the uranium region of the Colorado Plateau.

Report discussing a geological study of the Union Pacific prospect near the Golden Canyon in Jefferson County, Colorado.

Report discussing the geology of the Copper King mine area, which was worked for uranium following the discovery of pitchblende. The geology of the site is described as well as the history of the area's production.

Report summarizing the results of geological exploration of the Spring Creek Mesa area from July 11, 1951 to August 14, 1953. A brief description of the geology and ore deposits of the area is also given.

A report about a reconnaissance of the Sharon Springs member of the Pierre shale in western Kansas and eastern Colorado was conducted during 1954.

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.

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 report studies a group of wetlands in the Cottonwood Lake area in Stutsman County to explore "the role of lakes and wetlands in the hydrology of the prairie environment." It contains maps, graphs, and tables.

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, prepared principally to aid in the interpretation of the core drilling, presents the principal results of the field and preliminary laboratory work by the U.S. Geological Survey; it does not contain information obtained from the core drilling."
