Specimen Creek Ski Trail

Glimpses of mountain views can be seen through the trees along the Divide Ski Trail.

The Specimen Creek Ski Trail is an 8-mile (12.9-km) one-way trail that takes skiers through rolling forests. The trailhead is located 26.5 miles (42.6 km) north of West Yellowstone along US Highway 191. Avalanche Danger: Moderate to severe on the Shelf Lake Trail portion. This popular route follows the north side of Specimen Creek for 2 miles (3.2 km) through rolling forests to the Sportsman Lake Trail junction on the south (right). (Sportsman Lake Trail is not recommended). Follow the trail to the left along the north fork of Specimen Creek, ascending for 4 miles (6.4 km) through forests and meadows to Shelf Lake (the Crescent Lake trail junction). Shelf Lake lies 2 miles (3.2 km) north and Crescent Lake is 2 miles (3.2 km) east. Snow cover ranges from sparse to marginal on the lower reaches. The last mile of each trail is extremely steep; climbing skins are recommended.

Notes: Avalanche Danger is moderate to severe on the Shelf Lake Trail portion. Bison and elk frequent this trail. Federal regulations require you to stay at least 100 yards (91 m) away from bears and wolves, and at least 25 yards (23 m) away from bison and all other wild animals.
