The Illinois River creates a dynamic western boundary for this region, winding past a series of large riverine landforms including Twelvemile Island and Helmbold Island. This 2024 survey captures the intricate wetland ecosystem of the Two Rivers National Wildlife Refuge, where a complex network of backwaters like Upper Stump Lake, Flat Lake, and The Glades dominate the low-lying bottomlands.
