"The River that Flows Uphill: Geologic Evolution of the Lower Wisconsin River Valley, Stream Piracy, & Reorganization of North American Mid-Continent Drainage Systems." Eric Carson, geologist, Wisconsin Geological & Natural History Survey. Today’s lower Wisconsin River flows west across southwestern Wisconsin. Yet geologic evidence indicates that the lower Wisconsin River valley was carved by an eastward-flowing river. Glaciations rerouted rivers to create the Mississippi River system.
