 About a mile up Stampede Pass road the non-motorized (skiers, sled dogs) trail follows Forest Road 420 on the left and motorized (snowmobile) traffic stays right.These x-country ski trails are groomed by a grooming machine named Hippo owned by the Mountaineers and operated by their volunteers.This area is also where the Northwest Sled Dog Association holds their annual Crystal Dog Challenge on the groomed trails that pass through the area.
