ObservationsTriggered a wind slab in NE bowl of Ball Butte just off the summit on a convex rollover at the steepest part of the bowl, ~6 inch crown propagated for ~25 feet horizontally. Avalanche slid ~100 vertical feet. Insufficient volume of snow to bury a person not laying down in its path.
The face that slid had already had at least 7 skiers go down it that morning.
