Previous avalanche on South aspect in the top of the first gully of Tenderfoot. Possible human triggered (Ski tracks near avalanche and covered by avalanche debris as well) Unknown timeframe not previously reported.
Outside observation area on Sunday, Dec 18 at MP35.5 Moose Pass. Large natural avalanche witness by me at 11:19am. This avalanche made it to the valley floor and had a powder cloud associated with that avalanche.
