Department of Natural Resources officials continue to warn of the dangers of thin ice across the state. The latest warning comes after a Fairmont man fell through the ice on a lake near Trimont Sunday. Southern Minnesota DNR Information Officer Scott Roemhildt says the ice conditions have changed in recent days following rain and near-record high temps. Roemhildt says that the ice should be at least 4 inches thick to walk on, 5 inches thick to drive an ATV or snowmobile on, and 8-12 inches to take a vehicle out on. 68-year-old Richard Wolner of Fairmont was hospitalized after falling through the ice on Cedar Lake just northwest of Trimont Sunday evening. He was in chest deep water when a fisherman heard his cries for help, and he was rescued by the Trimont Fire Department and the South Central Minnesota Dive team.
