The Allegheny River carves a deep valley through Forest County, anchoring a landscape defined by the Pennsylvania oil industry and heavy timber. This mid-1960s survey reveals the dense distribution of oil wells and an active oil field concentrated west of the river on Preacher Hill and around Stewart Run. The river is punctuated by large landforms like King Island and Baker Island, while the surrounding uplands include the Cornplanter State Forest and the Allegheny National Forest.
