No, really. Not unusual for Minnesota, but still creepy!

Minnesotans saw scenes reminiscent of a Hollywood sci-fi spectacle this weekend when massive waves of ice surged out of the water and crept onto the shore like some fast-moving glacier.

Powerful gusts of wind drove giant sheets of ice toward townhouses hugging the southern lip of Lake Mille Lacs at the northwest end of the state.

Amateur video footage captured at the scene shows 2-foot blocks of wind-whipped ice jams stubbornly inching across residential patios at a speed of 2-feet-per-minute, according to NBC meteorologist Dylan Dreyer.

In one of the videos uploaded to YouTube, a woman can be heard comparing the sound of the ice blocks charging toward homes to that of a train chugging on tracks. Moments later, the ice sheets collide with homes facing the river, pressing intently on glass windows and doors.
