West Nile avalanche

Group skinned up low angle terrain and waited beneath rocks on climber's right. First skier crossed a supportive compression which had already cracked on approach but not slid due to the low angle and supportive shape. Skier came back to wait in rocky terrain higher on climber's right where rocks seemed to break up the terrain too much for a continuous bed surface. Second skier followed and regrouped with first. Third skier followed which triggered a steeper pocket higher up. Crown extended JUST far enough right to pull down the other three skiers in the broken terrain on the right. All skiers rode down slowly on the surface until the snow stopped. Debris was 50-100 cm deep on top of the existing snowpack.
