GIS Data for Geologic Map of the Challis 1 x 2 Degrees Quadrangle, Idaho
Description
This U.S. Geological Survey (USGS) data release provides an updated digital geospatial database for the geologic map of the Challis 1 degree x 2 degrees quadrangle, Idaho (Fisher and others, 2000). Attribute tables and geospatial features (points, lines and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the geologic map as published in USGS Miscellaneous Investigations Series Map I-1819 (Fisher and others, 1992). 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 4.4 million acre, geologically complex Challis 1 x 2 degrees quadrangle, at a publication scale of 1:250,000. The map covers primarily Boise, Custer, Lemhi and Valley Counties, but also includes minor parts of Elmore County. These GIS data supersede those in the interpretive report (Fisher and others, 2000).
