Geologic map datasets of the Custer and Gallatin National Forestsof South-central Montana, in ARC/INFO format: Absaroka-Beartooth study area

The digital ARC/INFO databases included in this directory provide a geologic map GIS database of the Absaroka-Beartooth study area (ABSA), a tract of approximately 1.4 million acres of National Forest land in southwestern Montana. 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.
