Abstract: During parts of July, August, and September 1951, a reconnaissance was conducted in parts of Colorado, Wyoming, Utah, and Idaho in search of new deposits of uranium-bearing carbonaceous rocks. One significant uranium occurrence was found, the Fall Creek deposit, Bonneville County, Idaho. Several additional localities were discovered that contain uranium in concentrations many times that normally found in carbonaceous rocks.

Report describing the phosphorite deposits of the western United States with the objective of outlining features that are common to both the Kara Tau phosphorite deposits of Russia and the western United States deposits in an effort to define their origin.

From purposes and approach of study: The primary purposes of this study were to: (1) Define, on a reconnaissance level, current (1980) water-quality conditions in major aquifers (water-yielding rock formations) in the western Snake River basin, Swan Falls to Glenns Ferry; (2) summarize and interpret available geologic and hydrologic data to assist in understanding the natural and man-cause factors that affect present and future understanding the natural and man-caused factors that affect present and future water-quality conditions; and (3) establish a hydrologic data base on which future data can be compared to evaluate changes. A secondary purpose was to evaluate the possible effects percolation of thermal water applied for irrigation may have on the quality of local, less mineralized, nonthermal ground water.

This report presents results of studies made on cenozoic sedimentary rocks in the western Snake River basin of Idaho to determine their favorability for uranium resources.
