This natural avalanche was estimated to have released late Tuesday night. An increase in wind along with plenty of low density snow formed numerous fresh drifts and wind slabs. A chunk of cornice falling onto the slope was the most likely trigger. With the debris being very crisp and visible, this tells us that the avalanche released late in the wind event just as the wind was about to slow down. This is the largest avalanche that I've seen from the recent couple of storms.
