A pickup truck broke through the ice on Fish Lake on Sunday morning, near a pressure ridge that the Minnesota Department of Natural Resources last week warned anglers and snowmobilers about.
The truck had ventured about 100 feet off the plowed ice road on Fish Lake north of Duluth in the vicinity of the pressure ridge near Birch Island, said Tim Wagner of Hi Banks Resort.
He cautioned anglers and others traveling the lake to stay on the ice road and not get near the pressure ridge. Wagner said the truck appeared to be slowly sinking through the ice in about 13 feet of water.
The pressure ridge originally formed Jan. 19 and became more pronounced last week, a DNR conservation officer said.
