This report presents the results of a uranium hydrogeochemical and stream sediment study made in the fall of 1976 of Boulder Batholith, Montana.

"This report describes work done in the Bozeman, Montana National Topographic Map Series (NTMS) quadrangle (1:250,000 scale) by the Hydrogeochemical and stream Sediment Reconnaissance (HSSR). The HSSR...is designed to identify areas having higher than normal concentrations of uranium in ground waters, surface waters, and water-transported sediments" (p. 1). In this project, 1251 water and 1536 sediment samples were collected from 1586 locations to test for uranium levels.

From introduction: This report presents data gathered in a Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) conducted by the Los Alamos Scientific Laboratory (LASL) in southwestern Montana. The HSSR was initiated by the US Department of Energy (DOE) to outline areas favorable for uranium exploration by examining uranium concentrations in natural waters and stream sediments.

From abstract: "This report is a compilation and evaluation of water-quality measurements that have been made by the U.S. Geological Survey at two stations on the North Fork Flathead River." It contains a map, graphs, and tables.
