We triggered a wind slab at 9400' on an East-facing slope while skinning up Bunnell's fork. Crown was about 150' wide and 10"-24" thick. The slide went about 100' then stopped on a lower angle slope. Avalanche broke about 20' above skier, who was then carried about 60'. Second skier observed from an adjacent slope and was not carried. No injuries and no burial. We heard and felt a loud whomph about 1 hr before this, so we tried to stay on low angle terrain, but with low visibility ended up on a steep slope anyway. Should've turned around when we heard the whomph.
