A report about the Lemhi Pass area in the Beaverhead Mountains, Lemhi County, Idaho, and Beaverhead County, Montana, which was undertaken to determine the area as a potential source of thorium.

This report describes the hydrology and evaluates the water resources of the ERTS, sets these in their regional perspective, and forecasts conditions and effects during future years.

Report issued by the U.S. Bureau of Mines discussing materials surveys conducted on mercury. As stated in the foreword, "the surveys dealing with metals and minerals summarize the demand-supply position in the United States and include information on production, imports, consumption, exports, substitutes, and pertinent history" (p. v). This report includes maps, tables, illustrations, and photographs.

Report regarding the chemical processing instrumentation designs and problems at the Idaho Chemical Processing Plant.

From Introduction: "Descriptions of the functional requirements of the facility, together with preliminary concepts of methods for meeting them, are presented in this prospectus."

From abstract: Approximately fifty radioactive deposits and nearly fifty properties not abnormally radioactive were examined during a geologic reconnaissance for radioactive minerals in Idaho, Washington, and western Montana during the period July 1952 -- June 1955. The most important uranium deposits are in or near granitic to quartz monzonitic intrusions of probable Cretaceous age in central and northern Idaho, westernmost Montana, and northeastern Washington.

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.

Photograph of the Series 90-S Mobile Spar. According to author Eric Orlemann, "the Mobile Spar was a diesel-electric transporter equipped with a folding 130-foot guy wire tower." It was built for hauling lumber up steep slopes. Only one unit was built and sold to a lumber company in McCall, Idaho.

Geologic factors in the physical environment of the National Reactor Testing Station control the amount and availability of the water supply, the methods and efficiency of obtaining water, and the behavior of waste materials that are disposed on the ground or beneath the land surface.

Abstract: The Murray area includes almost the whole drainage basins of Prichard, Eagle, and Beaver Creeks and is underlain by the pre-Cambrian Belt series which is subdivided, from oldest to youngest, as follows: Prichard formation (upper and lower parts), Burke formation, Revett quartzite, St. Regis formation, Wallace formation, and Striped Peak formation. The Belt series in this area is cut by many small monzonite stocks believed to be related to the Cretaceous Idaho batholith. This report describes only the lead-zinc mines. The lead-zinc production around Murray reached its peak in 1911 and 1912 when the Monarch, Edith Murray (Pontiac or Terrible Edith), Bear Top, Paragon, Black Horse, and Silver Strike mines were active. Many of these mines have produced ore intermittently since then, and the Jack Waite mine has been very active since about 1930.

From introduction: This report details the study to determine whether it might be worthwhile to attempt to recover uranium-bearing minerals that were previously dredged in a gold exploration in 1951 and discarded.

A report about uranium bearing multiple oxide minerals first recognized in the jig-bed concentrate of the Tyee Mining Company's gold dredge on the Red River. The gravels of the placer deposits were derived from the Idaho batholith and a roof pendant of Precambrian rocks in the batholith.

A report discussing an examination of the Dismal Swamp property for niobium, tantalum, and uranium.

From introduction: The principal objective of the program is to make detailed geologic maps of the areas in which important phosphate deposits in the Phorphoria formation occur. It is hoped that the maps will serve both as an aid in selecting possible sites for mining and as a basis for calculating reserves.

From summary: "This manual is designed for the purpose of clarifying operating procedures of the Materials Testing Reactor and its associated equipment. In assembling this manual a description of each item of equipment and its function is presented. In addition, the generally accepted method of operating the equipment and the best corrective measures concerning all emergencies that might be encountered are set forth herein. Descriptive drawings and written instructions pertaining to the equipment have been included to further clarify the manual."

From abstract: Uranium on the Hooper Tunnel level of the Crescent mine, Shoshone county, Idaho, occurs in two red, iron oxide-stained radioactive zones in and along the hanging wall of Alhambra fault.

"This report and accompanying maps summarize the status of ownership of many phosphate bearing lands in southeastern Idaho. Ownership categories are (1) phosphate rights owned by Federal Government, (2) phosphate rights not owned by Federal Government, and (3) ownership status uncertain"

From introduction: This report describes the general geologic setting, the occurrences of uranium or radioactivity in the Fall Creek, Idaho area and adjacent areas, the probable nature of the mineralization and origin of the deposits, and the estimated reserves of uranium-bearing rock.

Report discussing the geology and uraniferous carbonaceous rocks found in the Bear River of the Fall Creek area of Bonneville County, Idaho. The report provides information regarding the geology of the area, uranium occurrences, distribution of uranium and other elements in carbonaceous materials, origin of uranium occurrences, core drilling results, and inferred reserves.

Report discussing a program of core drilling to explore the underground extent and grade of uranium-bearing carbonaceous shale and lignite beds in the Goose Creek district during August and September 1953.

Discussing the results of core drilling for uranium-bearing carbonaceous shale and lignite in the Goose Creek District, in Cassia County, Idaho
