From abstract: The objective of the work was to define areas showing surface indications of a generally higher uranium content where detailed exploration for uranium would most likely be successful.

From abstract: All geologic conditions in the Dillon Quadrangle (Montana and Idaho) have been thoroughly examined, and, using National Uranium Resource Evaluation criteria, environments are favorable for uranium deposits along fractured zones of Precambrian Y metasediments, in the McGowan Creek Formation, and in some Tertiary sedimentary basins.

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 Introduction: "The Spokane Quadrangle, located in parts of Washington, Idaho, and Montana between lat 47º and 48º N. and long 116º and 118º W. (Fig. 1), was evaluated to identify and delineate areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits."

From Introduction: "The Challis Quadrangle, in central Idaho between lat 44º and 45º N. and long 114º and 116º W. (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits."

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 Pocatello 1º x 2º Quadrangle, Idaho (Fig. 1), was evaluated to identify geologic environments and to delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. Geologic environments were evaluated primarily on the basis of surface investigations, because only limited subsurface data were available."

From Purpose and Scope: "The Wells 2º Quadrangle, Nevada, Utah, and Idaho (Fig. 1), was evaluated to identify and delineate areas and geologic environments that exhibit characteristics favorable for the occurrence of uranium deposits. All geologic environments in the quadrangle were evaluated to a depth of 1500 m (5,000 ft) using all available surface and subsurface data."

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."

From Introduction: "The Baker Quadrangle, in east-central Oregon and west-central Idaho (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits."

From Introduction: "The Jordan Valley Quadrangle (Fig. 1), southeastern Oregon and southwestern Idaho, was evaluated to define areas that have geologic environments favorable for uranium deposits."

From Purpose and Scope: "The Dubois Quadrangle, Idaho and Montana (Fig. 1), was studied to identify geologic environments and delineate areas favorable for uranium deposits. These reports summarized field observations and contained preliminary evaluations of geologic environments for uranium deposition. The identification of environments favorable for uranium deposition involved collection and interpretation of radiometric, geochemical, and geologic data."
