Industrial activity defines this corner of McKean County, where the valley of Tuna Creek meets a dense network of timber and chemical processing sites. In the mid-1920s, the Nusbaum Chemical Plant and Hazelton Mills highlight the region's reliance on local natural resources, while the massive Kinzua Viaduct stands as a landmark of railroad engineering in the south. The settlement of Bradford serves as the primary hub, surrounded by smaller communities such as Derrick City, Lewis Run, and Custer City.
