This collection provides online access to a set of twelve maps of the Mississippi River including maps of the river streams and channels from Cairo, Illinois to Baton Rouge, Louisiana. The maps were prepared by the U.S. Army War College in 1941 through the Office of the Mississippi River Commission.
The twelve maps linked together form the whole of the river. Users can view the changes in the course of the river over time. The river course changes are color coded based on the date of the survey: Some of the maps include surveys from 1765, 1820-1830, 1881-1893; all of the maps include surveys from 1930-1932.
