The boundary between St. Clair Co and Monroe Co bisects this Illinois landscape, where small rural settlements like Paderborn and Smithton anchor the local geography. The area is defined by a dense network of winding waterways, most notably Prairie du Long Creek and its various tributaries including Rockhouse Creek and Toole Branch. These creeks carve through the terrain, separating upland fields from wooded drainage basins.
