From abstract: Between mid-May and late June 1976, 3409 water and water-transported sediment samples were collected from 1781 locations spread over an approximate 17 000 kilometer area of northwestern Montana. All of the samples were analyzed for total uranium at the LASL, using standardized procedures and rigorous quality controls--the waters by fluorometry and the sediment (and those waters with >10 parts per billion uranium) by delayed-neutron counting methods.

"This report presents engineering details, statistics, individual borehole histories, and geophysical logs of the four holes drilled in the Lemhi Pass, Montana/Idaho area." (from Introduction)

Report documenting the results of chemical analysis for 1370 water and 1951 sediment samples in the Butte quadrangle, Montana. It includes an overview of the area, methods, data analysis, and evaluation.

From Introduction: "The Sandpoint Quadrangle (Fig. 1) was evaluated to define areas with geologic environments favorable for uranium deposits. Environments were evaluated on the basis of surface investigations because few subsurface data were available."

Appendices containing data on uranium availability and sample analyses to accompany a report on U.S. uranium resources in the Sandpoint Quadrangle, Washington, Idaho, and Montana.

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.

"The purpose of this report is to present the results of a condition survey performed at Glasgow Air Force Base (GAFB), Montana, during 17-20 April 1972. The three major areas of interest considered in this condition survey were the structural condition of the primary airfield pavements, the condition of pavement repairs and the types of maintenance materials that have been used at this airfield, and any detrimental effects of frost to the pavement facilities" (p. 1).

Letter from Congressman Denny Rehberg to Commissioners of the Defense Base Closure and Realignment Commission (BRAC) extending an invitation to visit the Montana Air National Guard station and Malmstrom Air Force Base in Great Falls, Montana.

This volume contains information and survey results pertaining specifically to the Cut Bank NTMS 1:250,000-scale Quadrangle, Montana, one of a group of 12 such quadrangles in Arizona, Idaho, Montana, New Mexico, South Dakota, and Washington included in an aerial radiometric and magnetic reconnaissance survey. Information concerning the instrumentation and methods used in data acquisition, processing, and interpretation is presented in Volume 1 of this final report.

Appendix containing tables to accompany a report on aerial radiometric and magnetic reconnaissance survey of the Cut Bank Quadrangle.

This report contains aerial gamma-ray and magnetic survey maps of the Choteau Quadrangle.
