Report regarding the ongoing research and development related to the Army Gas-Cooled Reactor Systems Program. Includes status and progress of the program's projects, experiments, and data evaluations.

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.

Supplementary data containing elemental concentration data in rock samples in addition to sample location maps to accompany a report on U.S. uranium resources in Northeastern Washington and Northern Idaho.

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.

Appendices containing analyses of water, stream, and sediment samples to accompany a report on hydrogeochemical and stream sediment reconnaissance in Washington, Idaho, and Montana.

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.

Supplementary analytical data containing elemental concentration data in surface sediment samples and ground water samples, in addition to areal distribution maps, histograms, and cumulative frequency plots. Also included is site location data for surface and ground water samples, and a user's guide. This data accompanies a report on hydrogeochemical and stream sediment reconnaissance of the Baker 1° x 2° NTMS Area, Oregon and Idaho.
