The first skier of our group dropped in and triggered a slab after their first turn. The slope failed roughly 100 meters across and at it's deepest ~80cm. The skier was pulled through some small trees and stopped about 100 meters lower after they got tangled in a tree. The slide continued and petered out in the bottom of the slope as it flattened out. Aside from a bump on the arm and a lost ski pole the skier was okay. We went home after that
