Ice volcanoes commonly occur during the winter months along the north shore of Lake Superior.
Cones begin to form at the leading edge of the ice shelf as it builds out into the lake.
Here a video from an ice volcano video on Lake Erie in 2016
When the waves, driven by strong onshore winds, feel bottom they build and break onto the ice shelf.
After the ice shelf has built out, waves continue to travel underneath the ice and are forced up through cracks and previously formed cones. More on Strange Sounds and Steve Quayle.[Twitter, Michigan Tech]
