About this map

The confluence of the Wisconsin River and the Mississippi River dominates this mid-century landscape, highlighting a complex network of waterways including Johnsons Slough and Wyalusing Slough. This stretch of the river valley is anchored by the Upper Mississippi River Wildlife and Fish Refuge, which encompasses several large islands such as Island 176 and Island 178. On the Iowa side, the presence of Effigy Mounds National Monument and Pikes Peak State Park indicates the preservation of significant prehistoric earthworks and river bluffs.
