The Allegheny Mountains define the character of this 1983 survey, where heavy industry and vast public lands converge in north-central Pennsylvania. Extensive tracts of the Allegheny National Forest, Elk State Forest, and Moshannon State Forest dominate the landscape, interrupted by the deep valleys of the West Branch Susquehanna River and the Clarion River. This era shows the region as a critical energy and transit corridor, featuring active resource extraction at Dagus Mines and Coal Hollow.
