Goodness gracious, great balls of fire ice!
As the so-called “polar vortex” slowly releases its frigid grip on the Midwest, it’s leaving an odd site in its wake: gigantic, spherical ice balls that have taken over Lake Michigan. A YouTube user uploaded video of the phenomenon in Glen Arbor, Mich., yesterday. The clip shows thousands of rounded, boulder-sized ice balls bobbing up and down in the water.
The balls form when chunks break off the massive ice sheets that coat parts of the lake in the winter, Annie Lipscomb, a park ranger at the Sleeping Bear Dunes National Lakeshore, explained to MLive. They gain their shape as waves in the lake ceaselessly toss them about, slowly rolling them into spheres.
