This Open-File report is a digital geologic map database. This digital map database is compiled from previously published sources combined with some new mapping and modifications in nomenclature. The geologic map database delineates map units that are identified by general age and lithology following the stratigraphic nomenclature of the U. S. Geological Survey. For detailed descriptions of the units, their stratigraphic relations and sources of geologic mapping consult Yerkes and Campbell (1993).

This dataset is a polygon coverage of the thickness of the overburden of the Pocahontas No. 3 coal bed, in feet. It was produced by importing 1:100,000 (30-minute) and 1:24,000 scale (7.5-minute) digital elevation models (DEM) into ARC, and merging the lattices into one. The structure elevation grid for the Pocahontas No. 3 coal bed was subtracted from the surface elevation grid, creating overburden thickness. This grid was contoured within the known extent of the Pocahontas No. 3 coal bed into 200, 500, 1000, 2000, and 3000 foot lines. This vector file was imported to ARC. Polygon attributes include a code for the USGS overburden category (Coal Resource Classification of the U.S. Geological Survey, USGS, Circular...
