Avalanche: Portage / Placer
Location: Comet Peak - Placer Valley (Squirrel Flats) region
An older large natural avalanche was seen on the west face of Comet Peak above Squirrel Flats. This area is on the east side of the Placer Valley. Avalanche is believed to have released sometime during the tail end of the Dec 9-10 storm. It was seen on Wednesday (Dec 15) from the air.

Avalanche Details
Avalanche was roughly 1,200' wide and running 2,000' using google earth estimates. Depth is uncertain (4-6'?), but believed to have run on the early November facets. Trigger was new loading by wind and snow during the Dec 9-10 storm, possibly a cornice fall initiated it.
