Avalanche Details
Slab broke between the two of us in our party during the 9th and 10th pass of the day on the skin track, likely from a thin spot. Skier #1 stood atop the slab. Skier #2 was able to arrest on the bed surface almost immediately.
We quickly descended to verify that the other three skiers previously in the area (who we began the day with and left the zone before us) had successfully exited.
Our earlier ski partners had seen the crown from near the parking lot. Two returned to the area while the third drove for help if needed.
