About this map

The Mississippi River dominates this landscape, serving as a dynamic border between Muscatine County, Iowa, and Rock Island County, Illinois. Along its northern banks, the terrain is defined by a series of backwater channels and protected habitats, including the Mississippi River Islands State Wildlife Management Area, which encompasses large landmasses like Geneva Island and Hershey Island. This fluvial system of sloughs, such as Wyoming Slough and Andalusia Slough, illustrates the complex wetlands that have shaped the region's ecology and local commerce for generations.

On the bluffs above the river, the settlement pattern is marked by traditional rural centers and conservation sites. Illinois City sits on the southern prairie while Wildcat Den State Park and the Fairport State Fish Hatchery occupy the northern shore near the community of Fairport. Genealogy and local history are preserved in the numerous country churches and cemeteries scattered through the hills, including Sweetland Church and the Harker Cemetery, documenting the families who farmed the Buffalo Prairie and the township of Sweetland.
