Natural Avalanche at Carson Pass

I am assuming this slid naturally on 1/16/19, perhaps when temperatures increased. The weak layer and bed surface appeared to be the facet and crust combo. They were about 70 cms down in this location. The slope with the wide crown is barely 30 degrees if that. I measured 22 at the flank I was working on. The trigger was a cornice fall on a small but much steeper slope above. It appeared the avalanche wrapped around two low angle drainages, but some evidence of the slide has been obscured by more recent snowfall.
