The borough of Corsica sits at the heart of this landscape, positioned along the border where Clarion Co meets Jefferson County. By the late 1960s, the region's economy was clearly defined by a mix of heavy extractive industry and traditional rural settlements. Extensive strip mining operations are visible across the terrain, notably south of Roseville and near the Airway Beacon, leaving a distinct mark on the topography.
