The Allegheny River and Clarion River converge in this landscape, shaping the rugged boundaries between Butler, Clarion, and Armstrong counties. The city of Parker sits at this historic river junction, flanked by Columbia Hill and the waters of Thoms Run. The region is defined by a dense network of small communities and crossroads, including Petrolia, Bruin, and Karns City to the southwest, and West Monterey tucked into a sharp bend of the Allegheny.
