Reconnaissance geologic map of the Selway-Bitterroot Wilderness, Idaho County, Idaho, and Missoula and Ravalli counties, Montana
Margo I. Toth
1983, Miscellaneous Field Studies Map 1495-B
The Selway-Bitterroot Wilderness covers about 1.25 million acres in east-central Idaho and western Montana (fig. 1). The wilderness lies across the Bitterroot Range, which forms the boundary between Idaho and Montana, and includes large portions of the drainages of the Selway, Lochsa, and Bitterroot Rivers. Elevations range from 1,800 ft...
Map showing distribution of small-scale deformation structures in a part of the upper coastal plain of South Carolina and adjacent Georgia
R. C. McDowell, B. B. Houser
1983, Miscellaneous Field Studies Map 1538
As a contribution to the assessment of neotectonics in the area of the Upper Coastal Plain of South Carolina, field traverses were made between Columbia, S.C., and Augusta, Ga., in 1975 and early 1976 in order to locate and describe small-scale deformation structures within exposed Coastal Plain rocks. The study...

1983, Miscellaneous Field Studies Map 1474-C
This report is part of a series that assesses the mineral potential of the Gee Creek Wilderness (fig. 1). Other reports in the series describe the geology (Epstein, 1983a), geochemistry (Epstein, 1983b), and a summary interpretive report (Epstein, Gazdik, and Behum, 1983).  During the recent U.S. Bureau of Mines field investigation,...
