Visitors to the shores of Lake Michigan were greeted by an interesting sight this week, as waves lapped against hundreds of massive ice balls.
The balls, or boulders, as some have called them, are formed when water from the lake begins to freeze and is pushed ashore by wave action, according to AccuWeather.com Meteorologist Jim Andrews.
As the waves lap the shore, the ice is tumbled, smoothed and frozen into a round shape.
"It's possible that the ice is accreting like a snowball or like a hailstone, and that they keep growing," Andrews said.
While the process does require specific conditions, it's definitely not an abnormal event, he said.
