Ice volcanoes are a rare phenomenon that occurs along some of the shorelines of the Great Lakes. Ice volcanoes often range in size from around 3 feet to roughly the size of a house or sometimes even bigger. Ice volcanoes are a hollow cone of ice and snow that can appear to “erupt” with a mix of ice, water, and sleet as the water pressure from the lake waves builds up beneath it and the waves crash against the shore.
Ice volcanoes require a unique set of conditions including ground-level temperatures being slightly below freezing along with large lake waves measuring several feet high.
