This is one of the last remnants of the glaciers which carved the mountains and valleys of the park. During summer it becomes crevassed and is sometimes cut off. Beware of avalanche risk in winter. Sidle upwards to the bottom of the couloir from Cupola Basin Hut. The couloir is initially wide but narrows and steepens towards the top where a rope may be needed, and ends at the col in route 5.20. Alternatively, from a bivvy rock or campsites above the forest in the northern head of Cupola Creek climb bluffs to the bottom of the couloir. In winter, there is a technical frozen waterfall ice route (two pitches) on these bluffs.
