Avalanche - Castle Lake - Right Peak
Winds were blowing very strongly out of the south. The group was gathered on the top of Right Peak above Castle Lake. One skier decided to duck under a cornice out of the wind. As he dropped below the cornice, he triggered a small avalanche in which he was carried for about 5 feet before coming to rest in a small clump of trees where the slope angle was not as steep. The wind slab slid on the old snow surface. About 4 inches of snow had fallen but loaded on the westerly aspect to twice that amount, approx 8-10 inches.
Very windy, heavy snow, poor visibility. Winds were out of the west at 0900 and then switched to southwest/south at about 10 to 1030 hrs. Active wind loading and cross loading of slopes.
