Big ice balls appear on Lake Michigan’s surface every winter. For anyone unfamiliar with this phenomenon, this looks unreal. Is this another mystery, like the moving stones in Death Valley? Is this done by extraterrestrials? Are these special signs given us by the universe? If you’re waiting for a thrilling confirmation of these theories, prepare to be disappointed!
But if you love science, and are equally thrilled by scientific explanations of natural phenomena, you’ll be satisfied. These ice balls are formed under certain specific circumstances. When the water temperature on the Lake Michigan is a little below freezing temperature, small pieces of ice form in the water. With the movement of waves, additional water is added to these pieces of ice, making them bigger and in this way, ice balls are created.
Surprisingly, it is a regular phenomenon during winter in the Great Lakes. Locals call them “ice balls” or “ice boulders” and they can be as large as basketballs. Mother nature never ceases to amaze!
