Supplementary maps documenting data from the Bozeman Quadrangle. From text: "The Bozeman Quadrangle is south-central Montana was evaluated for geologic environments capable of containing uranium deposits to a depth of 1500 m (5,000 ft.). Most rock types and geographic areas were investigated by surface traverse, and hydrgeochemical data were collected from available well sites."

From Purpose: "The White Sulphur Springs Quadrangle, in west-central Montana between latitude 46º and 47ºN. and longitude 110º and 112ºW. (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits. Favorable environments, as determined by surface and subsurface investigations, are those that could contain uranium deposits of at least 100 tons U3O8 at an average not less than 100 ppm U3O8."

"This report presents engineering details, statistics, individual borehole histories and geophysical logs of the seven holes drilled in the Missoula/Bitterroot Drilling Program." (from Introduction)

A report discussing a drilling project with the objective of obtaining information to assess the favorability of the Tertiary sedimentary units in the Missoula and Bitterroot Valleys for uranium potential.

Results of reconnaissance surveys of the Lewistown quadrangle to determine the likelihood of uranium deposits of the area, and additional information about the location and classification of any deposits.

Final report regarding the National Logging Program for the National Uranium Resource Evaluation
