Magnitude and Frequency of Floods in Small Drainage Basins in Idaho (open access)

Magnitude and Frequency of Floods in Small Drainage Basins in Idaho

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.

Laboratory Study of Uranium-Bearing Carbonaceous Shale and Impure Coal from Goose Creek District, Cassia County, Idaho (open access)

Laboratory Study of Uranium-Bearing Carbonaceous Shale and Impure Coal from Goose Creek District, Cassia County, Idaho

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.

Preliminary Report on the Mineral Hill Monazite Deposits, Lemhi County, Idaho (open access)

Preliminary Report on the Mineral Hill Monazite Deposits, Lemhi County, Idaho

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.

Preliminary Report of Reconnaissance for Uraniferous Granitic Rocks in Montana, Idaho, Oregon, Washington, and California (open access)

Preliminary Report of Reconnaissance for Uraniferous Granitic Rocks in Montana, Idaho, Oregon, Washington, and California

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.
