Report discussing an investigation of the Centennial Range of Montana and Idaho, and the phosphate deposits of this area. Information on the geology of the area and deposits are given as well as information regarding the quality and location of phosphate deposits.

A preliminary report on the geology of the phosphate deposits located in the Centennial Range in Montana and Idaho.

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

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.

Data gathered at ground water sites in the Challis quadrangle, including applicable water chemistry measurements (e.g., pH, conductivity, alkalinity), physical measurements (e.g., temperature, well description, scintillometer readings), and elemental analyses.

Tabulated data gathered at surface sediment and groundwater sites in the Challis quadrangle, including applicable reconnaissance measurements and elemental analyses.

Detailed descriptions of the data report for Challis quadrangle, including (1) sample collection and field measurements, (2) formats, abbreviations, and codes in the data tables, (3) graphs and maps, and (4) quality assurance programs for sample collection and analysis.

From introduction: The data presented here are reconnaissance data intended for use in identifying broad areas for further study. While care has been taken to provide reliable sampling and analyses, verification of individual analyses is beyond the scope of this report. The data should be viewed statistically because "one-point anomalies" may be misleading. Regional trends, however, should be reliable. This report is one of a series presenting data obtained by SRL reconnaissance.

Supplementary analytical data containing elemental concentration data in surface sediment samples and ground water samples, in addition to areal distribution maps, histograms, and cumulative frequency plots. Also included is site location data for surface and ground water samples, and a user's guide. This data accompanies a report on hydrogeochemical and stream sediment reconnaissance of the Baker 1° x 2° NTMS Area, Oregon and Idaho.
