Climb the narrow cornered ice gully. Protection is limited usually because the ice although firmly there is not thick enough, high up on the climb for ice screws. The crux is getting around the bend in the narrow ice runnel at the large rock outcrop. Then the top is direct and easier.
This flow is towards the right side of Triple corners and almost to the Waimea wall, in the gully between the rock route Left el Diego and the buttress of Murk Trench. Walk up trail from Black Jack Boulders towards Starship Crag then to the toe of Triple Corners. Continue up to the right almost up to Waimea until you reach it.
Ice screws and bring small ones for the narrows.
