The combination of early winter cold, followed by milder temperatures and strong winds has put Lake Superior's ice on the move.

John Lenters of Lentic Environmental says the ice was going up and down on three foot to six foot swells. Due to 40 to 45 mph winds breaking up the ice, the ice was moving quickly and heading toward Harvey and Au Train.
