Observer Comments

Skier triggered avalanche on the Kitchen Wall at top of Common Bowl. Skiers had been making runs down the shallower aspects to the left and right earlier with no problem. Appears slope went due to moving to the steeper aspect and possibly things warming up as the day went on. Looks like the slide was the new snow that went on a bed surface of windslab/sun crust.
Skier was caught but managed to get to the edge of the slide and barely buried.
