Abstract:
This data is a digital representation of the 1:500,000 scale map, "General Surficial Geology of Montana," by Ross, Andres, and Witkind published by the U.S. Geological Survey in 1955. It consists of a polygon feature class depicting geologic formations and a line feature class depicting faults, dikes, and the extent of the continental ice sheet during the Ice Age.

The digitizing work is described in USGS Open File Report 95-691, available from the USGS or at https://ftpgeoinfo.msl.mt.gov/Documents/Metadata/Mt1955Geology.pdf.
