	Description:
		Abstract:
			This ArcView shapefile contains a representation of the
			lateral extent of the Ferris 31 study area in the Ferris
			coalfield, Hanna Basin, Wyoming. This theme
			was created specifically for the National Coal Resource
			Assessment in the Northern Rocky Mountains and Great
			Plains Region.
		Purpose:
			The Nation's coal resources are being assessed by the
			USGS.  This assessment identifies and characterizes
			the coal beds and coal zones that will provide the
			bulk of the Nation's coal-derived energy during the
			next few decades.  This assessment is different from
			previous USGS assessments because digital files
			and databases are being collected and stored in
			standardized formats, and being analyzed using a
			Geographic Information System (GIS).

				This source contributed linwork defining the outer edge
				of the Seminoe Reservoir, which was used todefine the
				northwestern portion of the Ferris 31 study limit.
		Process_Step:
			Process_Description:
				Each source map was scanned and  digitized. The
				digital line graph (DLG) information was imported into
				ARC/INFO. Desired lines from the dlg coverage were
				extracted. Portions of the boundary that were not
				defined by the maps available were generalized using
				a buffer 3 miles from the available data points.  All of the
				lines were joined to create one polygon coverage
				defining the Ferris 31 study limit.  The coverage was
				projected to geographic coordinates and converted to a
				shapefile in ArcView.
