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."

Supplementary documentation about geological and resource surveys of the Sandpoint quadrangle in the northwest United States.

Geophysical drilling logs produced by the Bendix Field Engineering Corporation for uranium drilling explorations in the Missoula and Bitterroot Valleys. "Most of the drill holes were geophysically logged from total depth to surface by Goodwell, Inc., logging units. The logs obtained included the following: Gamma-ray, spontaneous potential (SP), resistivity, neutron, caliper, and density. In-house BFEC units also logged several holes, obtaining potassium/uranium/thorium (KUT) logs from MB-2, MB-6, MB-8 and MB-12." from page 7 of report

Handwritten logs compiled by the Bendix Field Engineering Corporation containing lithologic descriptions of cuttings made for uranium drilling explorations in the Missoula and Bitterroot Valleys. The logs are organized by the type of sedimentary rock and depth of the sample.
