This geologic map was prepared as part of a study of digital methods and techniques as applied to complex geologic maps.
WSGS update in 2014. Gregory N. Green, and Patricia H. Drouillard digitized the Geologic Map of Wyoming in 1994. Pat Stamile of the USGS and Chris Arneson and Laisan Serebryakov of the University of Wyoming Water Resources Center provided digital review. Original Geologic Map of Wyoming, Love and Christiansen, 1985.

The geologic map was digitized from scribe sheets used to prepare the published Geologic Map of Wyoming (Love and Christiansen, 1985), consequently at a 1:500,000 scale. Stable base contact prints of the scribe sheets were scannned on a Tektronix 4991 digital scanner. The scanner automatically converts the scanned image to an ASCII vector format. These vectors were transferred to a VAX minicomputer, where they were loaded into Arc/Info. The dataset includes both linear and polygon features, with attributes derived from the original 1985 map.
