Mississippi River Frozen Solid, February 1905

A woman standing on the Mississippi River beneath the Eads Bridge at St. Louis, Missouri in 1905. Dozens of people can be seen standing behind her, walking across the frozen river.

When the Mississippi River freezes over, it’s called an “ice gorge.” The river froze completely in St. Louis at least 10 times between 1831 and 1938, before the completion of the Alton Lock and Dam.
