Geochemical reanalysis of rock and sediment samples from the Lower Middle Fork of the Salmon River collected as part of the Idaho Primitive Area Studies in the 1960’s through 1980’s

This is a geochemical data set from the reanalysis of 44 rock samples collected between 1966 and 1970, and 107 sediment samples collected in 1966 and 1967. These samples were collected by the U.S. Geological Survey for a study investigating the mineral resources of the Idaho Primitive Area (Cater et al., 1973). The samples are from the Lower Middle Fork of the Salmon River, including the tributaries of Big Creek, Camas Creek, Brush Creek, Wilson Creek, Waterfall Creek, Ship Island Creek, Reese Creek, Stoddard Creek, and Papoose Creek. The overall objective of this study is to characterize the regional impact of legacy mining for the Frank Church River of No Return Wilderness Area. Mary P. Rossillon (1981) explored...

Geologic map of the Strawberry Butte quadrangle, Meagher County, Montana

The Strawberry Butte quadrangle, scale 1:24,000, is a legacy map of the U.S. Geological Survey, made as part of the Montana Investigations Project to provide information on the stratigraphy, structure, and geologic history of the area. The quadrangle encompasses an area of about 132 km2 (51 mi2) in the southwest part of the Little Belt Mountains and is about 26 km (17 mi) north of White Sulphur Springs, county seat of Meagher County, Montana. Two contrasting geologic terranes form the area. The northern two-thirds of the quadrangle are underlain by Paleoproterozoic metagranite that contains some inclusions of metadiorite and biotite gneiss. A veneer of Middle Cambrian sedimentary rocks, including the Flathead Sandstone...
