The Allegheny River valley carves through the borderlands of McKean County, Pennsylvania, and New York, anchoring a landscape defined by deep-set hollows and tight-knit settlements. In this 2016 record, the borough of Eldred serves as a focal point near the river, while Duke Center and Prentisvale sit tucked into the drainage of Knapp Creek. The terrain is remarkably intricate, with numerous family-named valleys such as Berger Hollow, Beers Hollow, and Drake Hollow indicating generations of local land use and residency.
