Twelve people were injured Sunday after a fire broke out at a popular Michigan ski resort. The blaze erupted at the main lodge of Boyne Highlands in Harbor Springs at about 1:30 a.m., authorities said. The lodge said none of the injuries were life-threatening, although one victim was transported to a hospital in Grand Rapids, about 180 miles away. The cause of the fire remains unknown. About 40 percent of the lodge has been damaged.
