The Allegheny River carves a deep horseshoe bend in the northeast corner of this landscape, framing the wooded highlands of Rockland. The 1963 data reveals a region defined by its extractable resources and crossroads settlements, where the terrain is marked by numerous Strip Mines and extensive Oil Fields. Communities like Eau Claire and Clintonville serve as local hubs, while smaller family-named junctions such as Riddle Crossroads and Smith Corners dot the interior.
