Preliminary geologic map of the White Sulphur Springs 30' x 60' Quadrangle, Montana 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...

Geologic map of the Strawberry Butte 7.5' quadrangle, Meagher County, Montana 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...
Geologic map of the Strawberry Butte 7.5’ quadrangle, Meagher County, Montana 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...
Geologic map of the Nelson quadrangle, Lewis and Clark County, Montana 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...
