    Description:
      Abstract:
        Spatial Geologic Data Model for the Gunnison, Grand Mesa, Uncompahgre National 
        Forests Mineral Resource Assessment Area, Southwestern Colorado
        and Arc/Info versions of the Leadville, Durangeo and Montrose 2 degree
        quadrangles as well as the Colorado half of the Grand Junction, Moab and
        Cortez 2 degree quadrangles.
      Purpose:
        This dataset was developed to provide a geologic map GIS database of Leadville,
        Durangeo, and Montrose quadrangles as well as the eastern half of the Grand
        Junction, Moab and Cortez 2 degree quadrangles Colorado for use in spatial
        analysis for the Gunnison, Grand Mesa, Uncompahgre National Forests Mineral 
        Resource Assessment Area, Southwestern Colorado.

        Process_Description:
          Paper maps were digitized under contract for the Colorado Geological Survey and
          the USGS.  These digital files were attributed with formation name.  Additional
          attributes were added and the map was quality checked against original material
          at the USGS.
