WATCH: DNR shares video of "ice volcano" that formed along the shore of Green Bay

GREEN BAY (WITI) – When you think of a volcano, you typically think “hot” molten lava and ash, not ice!

the Wisconsin Department of Natural Resources has posted a video of a different kind of “volcano" -- this one made of ice, along the shore of Green Bay.

As the DNR explains, the “ice volcano” is formed when waves hit a shell of ice. At a weak spot in the ice, a hole forms, and water gushes through. The water splashes up and creates a mound with a hole in the middle, just like a volcano.

The DNR says the volcano has disappeared naturally since the video was shot.
