12 mile

Initiated at ridge top, but multiple crowns visible lower in the track as well. Wind loaded start zone, probably cornice failure trigger. Also heard a much larger avalanche in really big terrain across the valley on a wind loaded E/NE aspect. Visibility too poor to see start zone/crown, but could see a good pile of debris in the run out and most of the track scrubbed out. Good sz 2.5 at least, pretty far away to get more specific
