I triggered this sizable wind slab avalanche while stomping along Cornice Ridge. Unintentional in that it was quite a bit larger and the slope much more sensitive than I expected...
The avalanche was 1 to 2 feet deep and around 300 feet wide. The slab failed on a nice layer of faceted snow under the dusty layer from Friday night's wind. Most of the slab built with high winds on Sunday 11-22-09 and overnight.
Darren McAvoy took this shot of me examining the scene.
This is looking down the the chunk-filled path of the avalanche. The avalanche ran about 600 vertical feet down the the bench below the bowl.
