The Allegheny River defines the geography of this mid-century survey, winding past a series of river islands including Hemlock Island, King Island, and Baker Island. This corridor served as a vital artery for the region's early industry, evidenced by the numerous Oil Fields and individual oil wells scattered across the timbered slopes of the Allegheny National Forest. The map captures the interface between industrial extraction and conservation, with the Cornplanter State Forest protecting the ridges west of the river while the State Fish Hatchery operates near Tionesta in the south.
