The Mississippi River defines the western reaches of this Alexander County landscape, carving a wide path through the borderlands between Illinois and Missouri. The river's historical shifts are evident in the complex system of chutes and islands, including Devils Island and Picayune Island, which are separated from the mainland by Picayune Chute. To the east, the terrain transitions into the wooded ridges of the Shawnee National Forest, where steep drainages like Dongola Hollow and Blue Hollow cut through the upland topography.
