North Buttress

A climb recommended for experienced climbers only. Follow Summit Creek route to scree 200m above the toe of the buttress to a narrow couloir rising steeply from scree to crags above. A four metre step near the bottom requires friction holds. Above a ledge the couloir is walled by loose rock. Once on the buttress follow the jagged ridge around the upper basin rim to the summit. Note: Grade is unconfirmed.
