In Mille Lacs Lake in Minnesota, an ice tsunami started moving toward land at a rapid pace, destroying all property in its path. 40 mile per hour winds pushed ice off the lake onto 60 to 80 feet of land. The ice now covers about 2.5 miles of shoreline and some mounds grew as high as 30 feet! A conservation officer of the Minnesota Department of Natural Resources, Christopher Tetrault, explained that when the strong gusts of wind blew big chunks of ice, the chunks "heave up bits of lighter, melting ice closer to shore up on the land." More wind means more ice on the land.
Darla Johnson captured some of the event on video where you can see the ice engulfing bushes and gutters as it creeps toward houses on the shore. You can see the ice progress closer and closer to one house in particular until it breaks through the back door.
