( CNN ) -- The ice moves inexorably ashore , crackling as it goes like thousands of windows breaking . In minutes , it 's moved from the shoreline of a Minnesota lake to the walls of homes along the lake . `` It was just pushing and breaking and pushing and breaking , '' Darla Johnson , who made a video of Saturday 's `` ice tsunami '' on Mille Lacs Lake , told CNN affiliate WCCO-TV in Minneapolis . Johnson 's video had more than 275,000 views on YouTube by Monday morning . And once you watch it , you ca n't stop . It 's like a sci-fi movie , and there 's certainly science involved . Christopher Tetrault , a conservation officer for the area with the Minnesota Department of Natural Resources , said the weather event works like this : Strong winds blow heavy chunks of ice out in the lake toward the shore . Those chunks heave up bits of lighter , melting ice closer to shore up on the land . The more the wind blows , the more ice comes onto land . `` It basically has the same mechanism of an iceberg , '' said Todd Borek , a CNN meteorologist . `` Winds , but more so ocean currents , allow icebergs to drift . Same premise : A chunk of ice ( relatively shallow ) was pushed by a strong , sustained wind . The momentum of the ice sheet overcame the friction of the land . '' Tetrault said the ice came about 60 feet to 80 feet inland Saturday , getting as high as 30 feet in some places . The ice mass covered up about 2.5 miles of shoreline , he said . At least one home had 2 to 3 feet of ice spill through its patio glass doors , and some boathouses along the lake were destroyed , he said . It was something Tetrault , who 's only been stationed on Mille Lacs Lake for a few months , had n't seen before . But longtime locals told him they could n't remember anything similar since the 1950s . The same phenomenon was seen Friday on Dauphin Lake in Manitoba , about 75 miles northwest of Winnipeg , where a wall of ice up to 30 feet high destroyed six homes and damaged 14 others , according to a report from the Canadian Broadcasting Corp. `` This is worse than a flood , because with a flood , the water just goes through and it 's finished . With this , there 's still so much ice out on the lake that if the wind picks up again , it could start all over , '' homeowner Elaine Davis told the CBC . `` You know you 've got cement , concrete blocks and steel , and the ice goes through it like it 's just a toothpick , '' Dennis Stykalo , who also lost a home to the ice , told the CBC . `` It just shows the power . There is nothing you can do ; you just get out of the way and just watch . '' In Minnesota on Monday , people were watching the ice there melt , a steady rain helping the process , Tetrault said . Temperatures on Tuesday expected to be in the 80s or higher were also expected to help , both with the ice onshore and the larger sheet now 200 to 300 yards out into the lake , he said . Still , that ice mass was about 16 inches thick Monday , and the weather can change quickly in Minnesota . `` It 's not as significant as it was , '' Tetrault said , `` but you never know with what Mother Nature does .
