SAUGATUCK, Mich. — "Ice volcanoes" sound like something you'd see in a movie, but they've popped up amid the frigid temperatures in Michigan.
The "volcanoes" look to be erupting on a beach in Saugatuck along the Lake Michigan shoreline.
The National Weather Service says the volcanoes form at the edge of ice shelves, as waves battle the shore, and force water up through cones of ice.
"You'll never know what you'll find at the lake until you go out there," NWS Grand Rapids tweeted. "Today, it was volcanoes."
