Title:		Spatial geologic data model for the Gunnison, Grand Mesa, Uncompahgre National Forests Mineral Resource Assessment Area, southwestern Colorado and digital data for the Leadville, Montrose, Durango, and the Colorado parts of the Grand Junction, Moab, and Cortez 1 degree x 2 degree geologic maps
Author:		Day, W.C., Green, G.N., Knepper, D.H., and Phillips, R.C.
Original NGMDB identifier: 23482


Purpose: This file set is intended to make outdated Arc/INFO e00 files available as open-format shapefiles. No modification to files has been made. Projection was not changed. 

Process: e00 files were imported to coverage, then converted to shapefile using the ArcMap commands “Import from e00 (conversion)” and “Feature Class to Shapefile” respectively. Related tables were preserved by opening in ArcMap and exporting to txt.
