Avalanche Details

Skier 1 and Skier 2 transition at 2300. At around 2200, a steeper rollover was analyzed for potential release and planned accordingly.
Skier 1 went slightly left and went to a safe spot. Skier 2 got into the rollover with some speed and on the 2nd turn noticed a shooting crack and continued to skiers left to a high bench. The slope behind propagated towards the N of the ridge, releasing the N / NW aspect of the newer snow.
