Geography
The Hennepin Canal follows a natural low area between Hennepin and Rock Island. This is actually the ancient channel of the Mississippi River, which at one time flowed from Rock Island to Hennepin, and then south through what is now the Illinois River channel. The Illinoian Stage, about 300,000 to 132,000 years before present, blocked the Mississippi River near Rock Island, diverting the Mississippi into its modern channel.
