Comments: 

Based on tracks it looks like this was a remotely triggered slide from a snowmobile just off the lower portion of the right flank of the slide. Near the Sled track the slab was much thinner than above, perhaps 18". The crown depth looks like it is 1'-6' deep. I'm sure this even got someones attention! It looks like the event is at least a couple days old.
