Keystone Couloir Map

This is an awesome backcountry couloir that can be accessed by hiking the North and South Bowl bootpack and ducking under the boundary line on hikers' right. You must hike all the way to the summit of Wapiti Peak and then descend down the skiers' right summit ridge to the first notable line that you come across. There are two entrances into the couloir that are separated by a cliff. The skiers' left entrance is much more wide open and has a smaller cornice, but has more rocks to navigate. The skiers' right entrance is much steeper, much more narrow, and and has a bigger cornice drop-in. After the entrances, the couloir mellows out a bit and filters into the Wapiti Couloir's lower section. This is another standout line in this zone and is definitely worth doing on a tour of the area!



Steep skiing at 38-45 degrees. This requires very good technique and the risk of falling has serious consequences.
