This map is one of a series that shows the regional characteristics of the Upper Elkhorn No. 3 coal zone. The maps were prepared as part of the U.S. Geological Survey's National Coal Assessment Program, which compiles regional maps and databases that provide a comprehensive assessment of the most important coal beds in the nation. The Upper Elkhorn No. 3 coal zone has been one of the leading producers in the state of Kentucky and, in some areas, is of very high quality. Bed stratigraphy within the Upper Elkhorn No. 3 zone and coal thickness of the No. 3A coal are described in KGS Map and Chart Series 7 (series 12). The map shows mined-out areas and thickness characteristics of remaining coal. Figure 1 shows point-data locations, and Figure 2 shows tonnage calculations for the Upper Elkhorn No. 3A coal (also known as the Kellioka or "B" seam south of the Pine Mountain Fault).
