Preliminary geologic map of the White Sulphur Springs 30' x 60' Quadrangle, Montana
The geologic map of the White Sulphur Springs quadrangle, scale 1:100,000, was made as part of the Montana Investigations Project to provide new information on the stratigraphy, structure, and geologic history of the geologically complex area in west-central Montana. The quadrangle encompasses about 4,235 km2 (1,635 mi2), across part of the Smith River basin, the west end of the Little Belt Mount

Preliminary geologic map of the Townsend 30' x 60' quadrangle, Montana
The geologic map of the Townsend quadrangle, scale 1:100,000, was made as part of the Montana Investigations Project to provide new information on the stratigraphy, structure, and geologic history of this geologically complex area in west-central Montana. The quadrangle encompasses about 4,200 square km (1,640 square mi).

Hydrology of the Helena area bedrock, west-central Montana, 1993-98
The Generalized Bedrock Geologic Map of the Helena Area, West-Central Montana (plate 1 in the report) provides an intermediate-scale overview of bedrock in the Helena area. The geologic map has been compiled at a scale of 1:100,000 from the most widely available sources of geologic map information (see index to geologic mapping on pl. 1). That information has been updated by M.W. Reynolds for this

Toward digital geologic map standards: a progress report
Establishing modern scientific and technical standards for geologic maps and their derivative map products is vital to both producers and users of such maps as we move into an age of digital cartography. Application of earth-science data in complex geographic information systems, acceleration of geologic map production, and reduction of population costs require that national standards be developed

Preliminary geology of the Blacktail Mountain drilling site, Flathead County, Montana
Five argillitic green beds that alternate with six argillitic purple beds in the upper part of the Spokane Formation of the Belt Supergroup of Proterozoic Y age were sampled by 22 shallow core holes. The holes were drilled on a hexagonal pattern over an area about 50 m wide and 150 m long to obtain detailed information on environment of deposition and distribution of anomalous amounts of copper su

Geologic map of the Strawberry Butte 7.5' 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 Sp
Geologic map of the Strawberry Butte 7.5’ quadrangle, Meagher County, Montana
The 7.5′ Strawberry Butte quadrangle in Meagher County, Montana near the southwest margin of the Little Belt Mountains, encompasses two sharply different geologic terranes. The northern three-quarters of the quadrangle are underlain mainly by Paleoproterozoic granite gneiss, across which Middle Cambrian sedimentary rocks rest unconformably. An ancestral valley of probable late Eocene age, eroded

Geologic map of the Nelson quadrangle, Lewis and Clark County, Montana
The geologic map of the Nelson quadrangle, scale 1:24,000, was prepared as part of the Montana Investigations Project to provide new information on the stratigraphy, structure, and geologic history of an area in the geologically complex southern part of the Montana disturbed belt. In the Nelson area, rocks ranging in age from Middle Proterozoic through Cretaceous are exposed on three major thrust
Geologic map of the Hogback Mountain quadrangle, Lewis and Clark and Meagher Counties, Montana
