Title: GIS Data for Geologic Map of the Salmon National Forest and Vicinity, East-Central Idaho
Author: John D. Horton
Comments: The data release for the geologic map of the Salmon National Forest and vicinity, east-central Idaho, is a Geologic Map Schema (GeMS)-compliant version that updates the GIS files for the geologic map published in U.S. Geological Survey (USGS) Geologic Investigations Series Map I-2765 (Evans and Green, 2003). The updated digital data present the attribute tables and geospatial features (points, lines and polygons) in the format that meets GeMS requirements. This data release presents the geologic map as shown on the plates and captured in geospatial data for the published map. Minor errors, such as mistakes in line decoration or differences between the digital data and the map image, are corrected in this version. The database represents the geology for the 11,265 square kilometer, geologically complex Salmon National Forest in two plates, at a publication scale of 1:100,000. The map covers primarily Lemhi County, but also includes minor parts of Beaverhead, Custer, Idaho, Ravalli and Valley Counties. New geologic mapping was undertaken between 1990 and 2002 and synthesized with older published maps, providing significant stratigraphic and structural data, age data for intrusive rocks, and interpretations of geologic development. These GIS data supersede those in the interpretive report: Evans, K.V., Green, G.N., 2003, Geologic Map of the Salmon National Forest and Vicinity, East-Central Idaho: U.S. Geological Survey Geologic Investigations Series Map I-2765, scale 1:100,000, https://doi.org/10.3133/i2765.
Subject: Geologic Map Schema (GeMS)-compliant version for the geologic map of the Salmon National Forest and vicinity, west-central Idaho.
