Geologic map of the Salmon National Forest and vicinity, east-central Idaho

The geology of the Salmon National Forest, Idaho, was compiled from
published and unpublished sources and new field mapping by Evans, Lund,
Tysdal, and Winkler between 1997 and 2001. The geology was compiled
onto 1:100,000-scale topographic base maps for input into a geographic
information system (GIS). The digital geologic map database can be
queried in many ways to produce a variety of geologic maps.
