This 206-page PDF is a regionally consistent and integrated geologic spatial database for the Northern Rocky Mountains of Montana, Idaho, and eastern Washington. It brings forty-three 1:100,000- to 1:250,000-scale digital geologic maps into a common database format. The regional geologic database features ArcInfo coverage (NR_GEO) that contains spatial data for both lines (contacts, faults, fold axes, dikes, sills, veins, garnet isograd, boundaries) and polygons (geologic units). The database represents the original content of the published maps and provides easily used and consistent content.
