More information or comments about the avalanche:
Could not see the crown on this one, just the debris, which was buried by a fair amount of snow. My guess is it ran either early on 11/19 or late on 11/17 loading events. It's timing was earlier than the other two crowns, which clearly ran at the tail of the 11/19 event.
