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 summary: This report contains data collected during a geochemical survey for uranium in the Ashton National Topographic Map Series (NTMS) quadrangle of eastern Idaho, southwestern Montana, and northwestern Wyoming (Fig. 1) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide lydrogeochemical and Stream Sediment Reconnaissance (HSSR).

Report documenting the results of an aerial radiometric and magnetic reconnaissance survey of the Pocatello quadrangle in Idaho.

From introduction: This volume contains information and survey results pertaining specifically to the Twin Falls NTMS 1:250,000 scale Quadrangle, Idaho, one of a group of 12 such quadrangles in Arizona, Idaho, Montana, New Mexico, South Dakota, and Washington included in an aerial radiometric and magnetic reconnaissance survey. General information concerning the instrumentation and methods used in data acquisition, processing, and interpretation is presented in Volume 1 of this final report.

Appendix containing tables to accompany a report on aerial radiometric and magnetic reconnaissance survey of the Twin Fallas Quadrangle.

Appendix containing single-record and averaged-record data listings to accompany a report on aerial radiometric and magnetic reconnaissance of the Ritzville Quadrangle.

From summary: The purpose of this study was to delineate favorable areas for uranium resources in northeastern Washington and northern Idaho by identifying granitic rocks with relatively large amounts of uranium and (or) thorium. Results are based on analyses of 344 rock samples; 230 were collected during this study, and data for the rest were taken from previous publications.

From objectives: The principal objective of this work is to determine those areas that are favorable for concealed uranium deposits beneath the Challis Volcanic rocks in the area north of the Stanley Basin and south of the West Fork of Yankee Fork.

Report describing the results of geochemical and stream sediment reconnaissance sampling in the Sandpoint Quadrangle, to look for uranium and trace elements, and to take other measurements.

From introduction: The data presented here are reconnaissance data intended for use in identifying broad areas for further study. While care has been taken to provide reliable sampling and analyses, verification of individual analyses is beyond the scope of this report. The data should be viewed statistically because "one-point anomalies" may be misleading. Regional trends, however, should be reliable. This report is one of a series presenting data obtained by SRL reconnaissance.

Abstract: Field and laboratory data are presented for 410 water samples and 702 sediment samples from the Preston Quadrangle, Wyoming; Idaho. Uranium values have been reported by Los Alamos National Laboratory in Report GJBX-70(78). The samples were collected by Los Alamos National Laboratory; laboratory analysis and data reporting were performed by the Uranium Resource Evaluation Project at Oak Ridge, Tennessee.
