What years did the Mississippi River freeze?
The river froze over at St. Louis at least 10 times from 1831 to 1938, when completion of the Alton Lock and Dam corralled much of the ice from the upper Mississippi and Illinois rivers. Better weather often brought peril on the revived river. Disintegrating jams destroyed riverboats and freed surges of water.
