From Purpose and Scope: "The Gillette 1º x 2º Quadrangle, Wyoming, and South Dakota was evaluated to find volumes of rock considered favorable for uranium deposits and which could contain at least at 100 mt tons U3O8 with an average grade of 0.01 percent U3O8 or more. All geologic environments to a depth of 1,500 m (5,000 ft) evaluated through the use of surface investigations and subsurface information."

From Introduction: "The Butte Quadrangle, Montana (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. Each environment was categorized as favorable, unfavorable, or evaluated according to criteria established in Mickle and Mathews (eds., 1978)."

From Introduction: "The Elk City Quadrangle (1º by 2º), Idaho and Montana, was evaluated to identify and delineate geologic environments that exhibit characteristics favorable for the occurrence of uranium deposits."

From Introduction: "The Sheridan NTMS 1º by 2º Quadrangle (Fig. 1) in north-central Wyoming was evaluated to identify geologic environments that have characteristics favorable for uranium deposition. Only environments to a depth of 1500 m have been evaluated for this project."

This report is the first volume of a two-part set documenting the results of the analyses of the airborne gamma radiation and total magnetic field survey that was flown for the Dillon National Topographic Map NL12-7.
