    Description:
      Abstract:
        The geology of the Hebgen Lake Quadrangle was mapped as part of an 
        Ongoing research effort by the USGS to understand the geologic framework 
        of the area in and around Yellowstone National Park.  Prior to 1965 the 
        regional geology was known only from reconnaissance surveys.  Two 
        important components of this effort are an evaluation of (1) the seismic 
        risk hazard and (2) the mineral resource potential.
      Purpose:
        This ARC/INFO dataset was developed to provide a geologic map GIS 
        database of the Hebgen Lake quadrangle for use in spatial analysis by a 
        variety of users.

      Process_Step:
        Process_Description:
          Mike O'Neill, USGS Denver, and Bob Christiansen, USGS Menlo Park, 
          mapped and compiled the Hebgen Lake geology.  Mike Duncan, USGS 
          Denver, digitized previous published paper maps.  Paul Thale and Ken 
          Sandau, Montana Bureau of Mines and Geology, digitized the northwest 
          quarter of the Hebgen Lake quadrangle.  The pieces were combined by 
          MBMG and released as O'Neill and Christiansen (2002) and as an 
          Arc/Info database.  Greg Green, USGS Denver, checked the the line work 
          and polygons against the original maps.  The ARC/INFO database was 
          further edited by Green to correct deviations from published sources.  
          The digital database was quality checked by Alex Donatich, USGS 
          Denver.  The layout of the finished paper map was prepared by Alex 
          Donatich and checked by Mike O'Neill.
