This shapefile contains land status and Federal mineral ownership of the Green River Basin. The polygon shapefile contains two attributes of ownership information for each polygon. One attribute indicates where the surface is State owned, privately owned, or, if Federally owned, which Federal agency manages the land surface. The other attribute indicates which minerals, if any, are owned by the Federal govenment. This coverage is based on land status and Federal mineral ownership data compiled by the U.S. Geological Survey (USGS) and the Wyoming State Bureau of Land Management (BLM) at a scale of 1:24,000. These data were compiled primarily to serve the USGS National Coal Resource Assessment Projects in the Northern Rocky Mountains/Great Plains Region. The land and mineral ownership can be shown in relation to other relevant themes of this area.
