Chequamegon National Forest trail. This is a stacked loop system with loop lengths of 3.2 km and 8.6 km. What to Expect: In spite of being located in rugged terrain, the trail is suitable for skiers of moderate ability. Only the 8.6 km loop has climbs and downhills that demand intermediate skiing ability. The trail is groomed and tracked for classic technique skiing. Because of the lake-effect snow, this trail has some of the earliest skiing on the Great Divide Ranger District.
