From abstract: A reconnaissance to determine the uranium content of granitic rocks in the western states was made during parts of October and November 1951. The paucity of our knowledge of the granitic rocks that are most likely to contain significant quantities of uranium has prevented all but a very general isolation of areas or types of granitic rocks for reconnaissance examination.

From abstract: The Mineral Hill monazite deposits, 3 to 5 miles northeast of the town of Shoup, Lemhi County, Idaho, were investigated by the U. S. Geological Survey in July 1952. The deposits are replacement veins and lenses along shears in a pendant, principally of pre-Cambrian biotite gniess, about 4 to 5 miles in size and enclosed by granite of the Idaho batholith. The veins consist predominantly of calcite, monazite, and allanite, and contain minor quantities of barite, magnetite, rutile, and apatite.

The following report describes the petrography of uranium-bearing carbonaceous shale and a non-uranium-bearing impure coal from two of the drill cores that were used to explore the underground extent of the east-central part of the Goose Creek district.

Abstract: A method which relates basin characteristics with peak flow characteristics is presented for determining magnitude and frequency of floods on streams with drainage areas between 0.5 and 200 square miles. Regression equations for each of eight regions are presented for determination of the 10-year flood. Peak flows for the 25- and 50-year floods can then be estimated from ratios developed for each region. Regression equations are not developed because of poor definitions for several areas that total about 20,000 square miles. The equations were based on multiple-regression techniques using annual peaks and basin characteristics for 303 gaged sites.

This report contains data from a survey taken between August 11 and August 27, 1978 on the high sensitivity airborne gamma-ray spectrometer and magnetometer over the Ashton quadrangle in Idaho, Montana, and Wyoming.

Averaged record data listings taken during aerial gamma-ray and magnetic surveys of the Ashton quadrangle in Idaho, Montana, and Wyoming.

This report describes an investigation of the effects of stream channelization on fish and macro-invertebrates in low gradient reaches of Blacksmith Fork River and the Logan River in the floodplain of Cache Valley in northern Utah. Channelization adversely affected both fish and macro-invertebrate populations and biomass, with the severity of impact directly related to the amount and duration of disturbance of the physical habitat.

From abstract: All geologic conditions in the Dillon Quadrangle (Montana and Idaho) have been thoroughly examined, and, using National Uranium Resource Evaluation criteria, environments are favorable for uranium deposits along fractured zones of Precambrian Y metasediments, in the McGowan Creek Formation, and in some Tertiary sedimentary basins.

Appendices containing supplementary analytical data of stream-water and stream-sediment samples, in addition to geochemical analyses of rock samples for the Dillon and Dubois Quadrangles. Also included are detailed uranium-occurrence reports for twelve deposits in the Dillon quadrangle, which include including a description, uranium analysis, exact location, deposit type, and features of the host rock.

From Introduction: "The Baker Quadrangle, in east-central Oregon and west-central Idaho (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits."

Appendices containing data on uranium availability in the Baker Quadrangle to accompany a report on U.S. uranium resources in Oregon and Idaho.

From Introduction: "The Jordan Valley Quadrangle (Fig. 1), southeastern Oregon and southwestern Idaho, was evaluated to define areas that have geologic environments favorable for uranium deposits."
