This is a coverage of the Colorado Plateau coal assessment study area. The study area outline was drawn on the county lines that most closely outline the coal-bearing rocks in the Colorado Plateau Region. The county outlines originate from a national coverage for which lines were extracted from U.S. Census 1990 TIGER/line files using an AML program written by Nebert, D., and Negri, M., USGS-Water Resources Division (WRD), running on two Data General 6220 servers.

(topography, roadways, towns, andhydrography) are not included: they may be obtained from avariety of commercial and government sources. Geologic mapgraphics and plot files that are provided in the Open-FileReport are representations of the digital database and are notdesigned to be...
