Late Season Ice-Shove Event
Ice-shove is a relatively uncommon (but not rare) phenomena on big lakes like Lake Champlain (VT), Lake Winnebago (WI) and Utah Lake (UT). They are also called ice-push although that generally refers to the slow, rachetting, thermal pushing of ice into shore or objects in the lake . The ice is shoved by strong winds and/or collisions of wind blown or current driven ice sheets. Ice shoves often result in ice piles The pile formation process is quick (on the order of 15 minutes for a big pile) so it rarely witnessed. We had a particularly spectacular ice-shove event on April 7 when forty+ mph winds drove a large plate of well thawed ice back into Maquam Bay. The following are a couple of pictures and a map. More will be posted in the next few days.
More on this ice shove a week later
