More detailed information about the avalanche: 

I had checked out the rightmost Thompson couloir and, not liking the large cornice on top, skinned over to and partway up the leftmost Thompson couloir instead.  Tired of slogging up the steep, heavy powder, I transitioned an headed over to Ski Mountaineers Peak.  Another skier, who had apparently climbed the right couloir earlier, skied down the middle one and apparently triggered a decent-sized slide that buried my skin track.  The skier apparently waited for the slide to stop, then skied down through the debris and back to the trailhead.
