Observation: Turnagain

Skier triggered avalanche. Observed first skier ride out cleanly on my approach
to the summit. When I topped out I observed this crown. I assumed the second
skier dropping in triggered this. One of my ski partners said the debris ran to
the valley floor with two sets of ski tracks coming out. Myself and 5 others
skied down near the up-track, then onto the same south facing aspect without
incident.
