Ice Wedging

[image]

Definition
An ice wedge is a crack in the ground formed by a narrow or thin piece of ice that measures anywhere from 3 to 4 meters wide and extends downwards into the ground up to 10 inches. During the winter months, the water in the ground freezes and expands. Once temperatures reach -17 degrees Celsius or colder, the ice that has already formed acts like a solid and contracts to form cracks in the surface known as ice wedges. As this process continues over many years, ice wedges can grow up to the size of a swimming pool.[
