Upper Freeport Coal Bed Resource Areas in
Pennsylvania, Ohio, West Virginia, and Maryland
Description
This dataset is the digital compilation of geologic and resource maps provided
mostly by State geologic surveys and depicts the projected area of
occurrence of the Upper Freeport coal bed. The Upper Freeport coal bed is in
Ohio, West Virginia, western Pennsylvania, and western Maryland. The coal bed
may extend into eastern Kentucky, but correlations are highly uncertain and do
not warrant extrapolation south of the areas shown on this map at this time.
This dataset represents the extent of the Upper Freeport coal bed used in
the Apalachian coal region assessment. The file has been generalized from
detailed geologic coverages found elsewhere in Professional Paper 1625-C.
