Possible tracks in snow near Gwinn

Account

The witness and his wife were driving in their truck on a DNR access road toward a lake in fresh snow. The wife noticed a single file of large bipedal-looking tracks crossing the area near a toilet building. The husband got out, examined them in deep snow, and noted a long clean stride with no drag marks before the trail continued into pines. The pair reported seeing almost no deer sign in the area.
