The Illinois River serves as the central artery for this mid-century landscape, dividing Fulton and Mason Counties. In the north, the Chautauqua National Migratory Waterfowl Refuge dominates the eastern bank, centered on the expansive Lake Chautauqua. Opposite the wildlife refuge, the western hills reveal a deep archaeological history with Dickson Mounds State Park and Ogden Mounds located near the small settlement of Sepo.
