| Digital Geologic Quadrangle Maps - paper copies are print-on-demand products and size will vary from map to map.
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.
The primary purpose of these geologic maps is to show the geologic formations present at the surface at a 1:24,000 scale. The contacts were drawn on a 7.5 minute quadrangle base and then digitized by a cartographer in ArcGIS ArcView 9.0. Interpretations were made where outcrops were covered by unconsolidated sediment or vegetation. The cross-section was drawn using surficial data that was projected into the subsurface. Photographic or digital enlargement of these maps to scales greater than that at which they were originally mapped can cause misinterpretation of the data.
