Snow Profile

General Comments

Experienced numerous localized collapsing while ascending, mostly just around my skis but a couple collapsed to about a 25 foot diameter. Quick hand pits revealed very wet grains under the new snow which was what was collapsing. The avalanche released from 100 to 200 feet away. The slab itself was dry however the weakness was no doubt wet grains about 4" below the new snow/old snow interface.
