Provide digital maps and databases that, because of their common structure and format, allow creation of regional maps that depict age and lithology of map units.

Map unit designations follow original compilation faithfully. Additional information about age and lithology was obtained from the paper map legend and geologic literature.
The geologic map was digitized from compilations ranging in scale from 1:100,000 to 1:1,000,000, and is an accurate representation of the source maps. It is intended to be used at scales equal to or smaller than 1:500,000. Display at significantly larger scales may produce error in location of contacts or faults relative to features contained in other data sets. The state boundary arcs are based on the 1:100,000 scale USGS topographic map series digital line graphs.
The dataset contains all the map units and faults that were portrayed on the original printed map. Bodies of water are classified as water, and geologic units underlying them are not portrayed.
All internal polygons were checked for closure. Overshoots and undershoots have been deleted or corrected as appropriate.
