From abstract: Between mid-May and late June 1976, 3409 water and water-transported sediment samples were collected from 1781 locations spread over an approximate 17 000 kilometer area of northwestern Montana. All of the samples were analyzed for total uranium at the LASL, using standardized procedures and rigorous quality controls--the waters by fluorometry and the sediment (and those waters with >10 parts per billion uranium) by delayed-neutron counting methods.

"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.

"This report contains data collected during a geochemical survey for uranium in the Lewistown National Topographic Map Series (NTMS) quadrangle of Montana (Fig. 1) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR). [...] The HSSR program is part of the United States Department of Energy's (DOE) National Uranium Resource Evaluation (NURE), which is designed to provide an improved estimate of the availability and economics of nuclear fuel resources and to make available to industry information for use in the development and production of uranium resources" (p. 1).

Report of elemental date from a Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) of the Hamilton National Topographic Map Series (NTMS) quadrangle in Montana/Idaho: "The HSSR is part of the United States Department of Energy's National Uranium Resource Evaluation (NURE), which is designed to provide improved estimates of the availability and economics of nuclear fuel resources and make available to industry information for use in the development and production of uranium resources" (p. 1).

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 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).

From summary: This report contains data collected during a geochemical survey for uranium in the Billings National Topographic Map Series (NTMS) quadrangle of south-central Montana (Fig. 1) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

This report provides uranium and other elemental data resulting from the Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) of the Dillon quadrangle, Montana/Idaho.
