Ice shelf warning along Lake Michigan from Ind. officials

February 10, 2014 (MICHIGAN CITY, Ind.)

Officials said in a statement they had received numerous calls about people walking on the ice shelves at Washington Park and taking children on sleds out on them.

Michigan City police issued a statement, "Shelf ice can be beautiful to look at but very deadly to walk on! Due to the recent frigid and then warming temperatures the expanses of ice at Washington Park and the entire Lakeshore could collapse extremely quick breaking off without warning possibly causing injury or death.

Shelf ice can form when blocks of ice get blown against the shoreline and freeze together in clumps. Even though shelf ice may look solid, it's not, officials said.
