Mississippi River bottomlands and the rugged bluffs of Calhoun County define this landscape, where the river divides Illinois from Missouri. The settlement of Hamburg sits at the river's edge, while Hardin occupies the southeastern reach near the Lincoln Valley. This area is characterized by a complex network of side channels and wetlands, including Westport Chute, Kickapoo Chute, and numerous named islands like Schwanigan Island and Eagle Island.
