I stumbled upon the remnants of this avalanche on my morning walkabout. It appears to have been skier triggered- likely intentional- as the ridge/cornice looked to have been molested by pole whacks and skier stomping. Lots of cracking around the flanks of the slide. It appeared to run the entire chute, although I couldn't see the bottom. This likely occurred yesterday or possibly early this morning. There were ski tracks on the bed surface and a booter right back up to the ridge. Unknown if someone took a ride (and a skier went down to help after) or if a skier just decided to, post avalanche, ski the faceted bed surface for.... missing gear or a photo op?

FORECASTER COMMENTS: While the actual trigger is unknown, Miss Kendall has good speculation on the trigger being a skier. Furthermore, the fact that you can see "creep" in the crown (2nd photo below where the crown appears to be drooping downhill) indicates that the crown has sat around for a day or so. Lack of fresh snow on top of the bed surface indicates it occurred AFTER it stopped snowing AND the wind stopped transporting snow. This would put the most likely timing sometime on Sunday. Maybe someone will confirm the speculation. -Kobernik

New snow, some wind loading and a faceted bottom just needed a little tickle to get rolling on the 42 degree NE facing slope. 15" crown (all new snow) on top of 4" of facets.

A thin crust (wind?), at the old/new snow interface, provided a good sliding surface in the start zone.
