Avalanche Details

Skier #2 in the couloir trigger a wind slab on second turn. Slab propagated about 50ft across/along side the couloir (see photo). Due to where I was standing, I was not able to see how far it ran down the couloir. Maybe halfway? Skier was able to ski skiers left and allowed debri to run without being involved. Due to terrain, slide could have possibly carried or caused injury to skier. Talked to Skier #1 on the return booter and stated he only initiated small slough.
