A popular ice route up the Enclosure with less rockfall danger than the Black Ice, the Enclosure Couloir meets up with the Northwest Ridge, from where one can continue to the summit of the Enclosure.

Routefinding is easy: follow the 50-degree couloir to the notch in the Northwest Ridge. Then continue up the ridge or rappel the other side to return to the Valhalla Traverse and Lower Saddle.


Follow the Valhalla traverse around the back of the Enclosure. The first couloir on the right is the Enclosure Ice Couloir. Continuing the traverse up and left reaches the Black Ice Couloir.


Light rock rack with a minimum of screws in early season to 6-8 screws for late season ice
