Comments
Small size one triggered by snowmobile on a slope test. Very short runout. Triggered near the ridge line when the storm snow was thinner, several small trees and rocks at the crown. Considerable wind effect was noted during the day. We rode conservatively in tight trees and lower angle slopes.
