North Icefield Couloir

May be climbed in an icy winter via the narrow, tall (190m) and steep
(45º–80º) couloir leading directly to the summit rocks from the head of
the northern snow/icefield. The crux is met approximately 70m below the
summit, where the ice/snow clings to an almost vertical rock-band and a
cornice may exist across its head. Descend via the North Ridge.
