The avalanche forecast has been warning of large and sensitive cornices for several day. This large avalanche was triggered from a cornice naturally shearing off 200'+ above at the top of the cliff band. The bed surface had the small amount of snow from Thursday's storm so this slide most likely occurred on Tuesday or Wednesday (April 11 or 12). The avalanche ran to the flat below and had chest freezer-size debris chunks.
Seeing this slide really drove home being aware of what is above you when you are in big terrain.
