Pressure Ridge
This is a large stress crack on Lake Manitoba. All cracks in ice are caused by stress in the ice which mostly comes from temperature changes in the ice sheet, wind and waves. These cracks can run for miles across a lake and are something fishermen and snowmobilers must be very aware of. In the spring the ice can pile up so high it visually looks like mountains out on the lake
