The ABSA is adjacent to the northern part of Yellowstone National Park, and includes southeastern parts of Gallatin National Forest and western parts of the Custer National Forest. The geologic map was originally prepared to accompany a U.S. Geological Survey evaluation of the mineral resource potential within the ABSA. The results of this mineral resource assessment were published as U.S. Geological Survey Open-File Report 93-207 and the geologic map was plate 1 of this report. The enclosed ARC/INFO database was created directly from the base materials used to create the geologic map (plate 1) in the ABSA report. Purpose: This dataset was developed to provide a geologic map GIS database of the Custer and Gallatin National Forests in the Absaroka-Beartooth study area for use in spatial analysis by a variety of users.

Mr. Silkwood then attributed the digital linework and polygons in ARC/INFO. The lines and polygons attributes were checked against the orginal and corrected to to match the published paper map as neccessary. Shadeset and lineset attributes were added in ARC. This ARC database was further edited by Gregory Green to correct further minor deviations from the published map. The digital database was quality checked against original materials by Bradley Van Gosen.
