The confluence of the Mississippi River and the Ohio River dominates this landscape, where the borders of Illinois, Missouri, and Kentucky meet at a complex hydrological junction. At the heart of this river system lies Cairo, positioned near Cairo Point, while across the water in Missouri, the terrain is defined by a network of drainage systems like Bayou Ditch, Brewer Lake Ditch, and Fish Lake Ditch that manage the low-lying alluvial plains. This environment is characterized by distinct landforms such as Angelo Towhead in the river channel and Rushs Ridge further inland.
