Video of huge balls of ice washing up on a portion of the shore of Lake Michigan.
In the video, filmed at the pier of St Joseph Lighthouse on December 29, the particularly large ice balls are seen being tossed around by the waves in the lake.
The filmer writes: "Unique ice balls forming along the shore of Lake Michigan. The balls form when chunks break off massive ice sheets on the lake in winter. They gain their shape as waves in the lake ceaselessly toss them about, slowly rolling them into spheres. These ice balls are larger than they normally get."
Some parts of the US state have experienced record low temperatures over the Christmas period, according to local reports.
