The purpose of the data release is to produce a Geologic Map Schema(GeMS)-compliant version for the geologic and structure maps of the Wallace 1 x 2 degrees quadrangle, Montana and Idaho, that updates the geospatial data published as part of the U.S. Geological Survey Miscellaneous Investigations Series Map I-1509-A (Harrison and others, 2000). Conversion and publication of the geologic map in modern GIS format (e.g. ArcInfo coverages converted to ArcGIS geodatabases) is considered to be foundational and high-priority by the Mineral Resources Program to facilitate ongoing research and other activities by USGS Mineral Resources Program pertaining to critical mineral deposits as well as to other geologic mapping, petrologic studies, and mineral resource assessments. The data reside in the National Geologic Map Database (NGMDB) distributed archive of standardized geoscience information for the nation.
