1991 Map of Illinois City

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.
