USGS Topo · Published 2021About this map
The Mississippi River forms a wide, intricate boundary between Illinois and Iowa, shaping the local geography through its many islands and backwaters like Upper Brown Lake and West Hickory Lake. Along the eastern banks in Jo Daviess and Carroll Counties, the landscape rises toward landmarks such as Heer Hill, with the Apple River cutting through the terrain to join the great waterway. Small communities and historical points of interest are scattered throughout this riverine corridor, including Blackhawk, Arnold, and Marcus.
