Huge Lake Michigan Ice Shelf Breaks Off and Floats Away
Captured by the WGN cameras at the top of the former John Hancock Center, this amazing time lapse video shows a giant chunk of ice break loose and float away across Lake Michigan. The lake is know for freezing over during Chicago winters. Depending on the thickness of the ice, it can stay that way well into spring. It's always dangerous to try to walk on the frozen lake, so visitors and Chicagoans alike are advised to stay off the ice. You can see this view and many other dramatic moments from the 94th floor of 875 North Michigan Avenue (formerly the John Hancock Center) at 360 CHICAGO Observation Deck.
