Avalanche Details

The sight of the day was a very large avalanche that had been triggered by a cornice fall sometime after Sunday's storm—or toward the tail end of it. We estimate the debris pile to be in the D3 range. As you can see from the photo, the avalanche took the entire snowpack with it. Of note, I observed a much smaller cornice-triggered wind slab on the same aspect in PMS bowl on Saturday which also ran to the ground.

Besides the big one, we saw mid storm crowns on almost every aspect—all were mid slope. We did not see anything that screamed buried surface hoar as the culprit. There were also quite a few sizeable dry loose slides on every aspect. Also, a very large windslab crown on the southern slope down to Bench Creek.
