The Illinois River corridor defines the landscape of this region, separating the floodplains of Pike Co from the eastern bluffs of Greene Co. A string of river islands, including Buckhorn Island, Weson Island, and Bridge Island, follows the channel southward toward the junction with Calhoun Co. The settlement of Pearl sits on the western bank, while Hillview and Grand Pass occupy the flatlands to the east, illustrating the historical reliance on the river for transport and commerce.
