Comments
Three separate slides in near proximity to one and other. Not sure the trigger, though possible they were remotely triggered from the ridge or some released in sympathy to an initial slide.
Forecaster note: UAC staff were on the ridge several days later and saw tracks that appeared to have triggered this slide remotely. What's interesting is the lower slide that appears to have occured sympathetically. Second photo was taken by us at the ridgetop where it was likely remotely triggered.
Also: In the foreground of the first picture, you can see a faint avalanche crown/flank from this slide on December 19.
