Digital Geologic Map File Footprints
The Digital Geologic Quadrangle Maps (DGM) series is a collection of geologic maps produced at a 1:24,000 scale. Most of these maps were produced in cooperation with the USGS through Cooperative Geologic Mapping Programs. Each map contains geologic formation contacts, fault, structure, and attitude of bedding (strike and dip) data at a 1:24,000 scale. Also included on most of the maps are a cross-section, correlation and description of map units, references, and a stratigraphic column for the quadrangle.
