The data release for the geology of Payette National Forest and vicinity, west-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) Professional Paper 1666 (Lund, 2004). 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 published Professional Paper 1666. 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 2.3 million-acre, geologically complex Payette National Forest in two plates, at a publication scale of 1:100,000. The map covers primarily Adams, Idaho, Valley, and Washington Counties, but also includes minor parts of Gem, Custer, and Lemhi Counties. New geologic mapping was undertaken between 1991 and 2003 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: Lund, K., 2004, Geology of the Payette National Forest and vicinity, west-central Idaho: U.S. Geological Survey Professional Paper 1666, 89 p., 2 plates, scale 1:100,000, https://doi.org/10.3133/pp1666.
