This natural avalanche occurred overnight 11-13-2011/11-14-20.... The area is heavily loaded by strong westerly winds like those from over the weekend...

By the looks of it, the 2 foot deep by around 100' wide avalanche ran on faceted snow just above the solid early October snow. I observed and red flagged the layer late last week.... Here's a link
