The ice on the Monongahela River above Pittsburgh breaks suddenly, causing heavy damage

The ice on the Monongahela River gave way suddenly in the morning just about Pittsburgh, Pennsylvania. The newly freed river carried massive sections of ice with some violence down through the docks, bridges, and moorings of the city and scores of vessels, including fully loaded barges and the ferry Black Hawk, were carried away.  Commercial damage on the busy river was considerable.  (By John Osborne)
