The Allegheny River and Clarion River define this corner of Pennsylvania during the early 1920s, a period when the timber and industrial heritage of the region was transitioning into conserved lands like the Allegheny National Forest. The landscape is densely marked with the remnants of late-19th-century rural life, specifically through an exceptional density of country schools such as Oldtown School, Smoky Hill School, and the Highland Township High School.
