1983 Map of Prairie Du Chien

About this map

The Mississippi River valley serves as a dramatic borderland between Iowa and Wisconsin, dominated by the urban center of Prairie Du Chien on the eastern bank. This riverine landscape is defined by a complex network of channels and islands, including the Upper Mississippi River Wild Life and Fish Refuge and islands such as Scrogum Island and Roseau Island. The map shows the convergence of the Wisconsin River from the southeast and the Yellow River from the west, creating a significant waterway junction.
