Cathedral Mountain is a big and popular ski ascent in the Rockies that presents some alternative descents, if conditions are prime. This is a complex tour, as it involves bootpacking and high exposure, so it should only be attempted during stable snow conditions. Bringing along your ski crampons is recommended as the summit ridge can often present some very hard packed snow.
Approach: Park at the Lake O’Hara parking lot and follow the road for about 3km. Veer right and cross the creek, after which you’ll be presented with some steep trees. Eventually the trees will open to a large basin. Continue heading into the basin until you see the south couloir.
Descent: Descend the same way, or, if conditions permit, the North Couloir is an alternative, descent.
