Skier triggered wind slab avalanche on Andesite Peak.

My partner and I saw the signs of this avalanche from the ski track. It happened sometime between noon and 1 pm. This was a soft wind slab with some loose dry characteristics. Some soft slab debris were visible. Skier entered the steepest most wind loaded portion of this slope and triggered the avalanche on the second turn. Tracks indicated that the skier had and skied out of it. Four previous tracks had been made in the lower angle portion of the slope to skier's right prior to the avalanche occurrence.
