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."

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.

This report is the second 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. This volume includes the flight line magnetic field, temperature, pressure, altitude data plus magnetic field data as measured at a base station.

The following report is a collection of maps documenting the findings from the airborne gamma-ray spectrometer and magnetometer survey in the Du Bois Quadrangle.

This report documents the airborne gamma-ray spectrometer and magnetometer survey over the Du Bois quadrangle in Idaho, Montana, the study takes place between August 29 and September 21, 1978.

This report contains data from a survey taken between August 11 and August 27, 1978 on the high sensitivity airborne gamma-ray spectrometer and magnetometer over the Ashton quadrangle in Idaho, Montana, and Wyoming.

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."

From Abstract: "The Ashton Quadrangle, Idaho, Montana, and Wyoming, was evaluated to identify and delineate areas containing environments favorable for uranium deposits, using criteria developed for the National Uranium Resource Evaluation program. Aerial radiometric data were evaluated, and anomalies were examined in the field. Fourteen uranium occurrences were noted in the study area."
