Highland and the settlement of Centerville anchor the southeastern portion of this Iowa County landscape, where the topography is defined by a series of prominent ridges and drainage basins. Bohemian Ridge and Farmers Ridge stand as high ground above the many winding tributaries, including the Blue River, Sixmile Branch, and Big Spring Branch. The road network follows the ancient contours of the land, with routes like Snowbottom Rd and Dry Bone Rd connecting valley floors to the higher elevations.
