USGS Topo · Published 2022About this map
The Mississippi River creates a dynamic border between Iowa and Wisconsin on this sheet, carving a complex landscape of islands and sloughs along the Upper Mississippi River National Wildlife and Fish Refuge. On the western bluffs, the protected grounds of Effigy Mounds National Monument stand near Pikes Peak, marking a terrain of deep significance. The river valley is punctuated by several large landforms including Island 178 and Island Number One Hundred Seventy-seven, which are separated by narrow channels like Wyalusing Slough and Johnsons Slough.
