The Allegheny River and Sinnemahoning Creek headwaters define this rugged landscape at the border of McKean, Potter, and Cameron counties. This mid-century survey reveals a region deeply tied to its mountain topography, where small settlements like Keating Summit, Austin, and Costello are strung along narrow valley corridors. The Pennsylvania railroad winds through the north, crossing the divide at Keating Summit, a critical point in the local rail network of the era.
