	Description:
		Abstract:
			This ArcView shapefile contains the major Hydrology  for
			the area in and around the Powder River Basin, located
			within the Northern Rocky Mountain and Great Plains Coal
			Assessment Area. This area can be viewed in relation to
			rivers, geology, and other relevant themes.
		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, stored and analyzed in
			formats using a Geographic Information System
			(GIS).
		Supplemental_Information:
			This data was specifically created for The Northern Rocky
			Mountains and Great Plains Region ArcView Project.  Its
			sole purpose is for graphical representation, and should not
			be used for analysis.  Any concerns question, or comments
			regarding this data should be direct to The USGS Earth
			Resources Observation Systems (EROS) Data Center.

				The following 100k dlg quadrangles were used for the
				Powder River Basin. Burgess Junction, Sheridan, Recluse,
				Devils Tower, Buffalo, Gillette, Sundance, Kaycee, Reno
				Junction, Newcasle, Midwest, Bill, and Lance Creek.
		Process_Step:
			Process_Description:
				The nessessary dlg files (in Spatial Data Transfer Standard
				(SDTS) format) were downloaded, unzipped and untared.
				They were then imported into ARC/INFO using the
				SDTSIMPORT command.  The coverages were then
				appended to create a single coverage. The coverage was
				then projected to a geographic coordinate system and
				converted to a shape file in ArcView.
