Corsica and Roseville anchor this survey of the upland drainage between the Clarion Co and Jefferson Co border. The landscape is defined by the deep dissection of the plateau by Redbank Creek and its many tributaries, including Little Piney Creek and Mill Creek. This topography influenced the placement of early settlements and roads, which largely follow the higher ridges or trace the winding valley floors.
