Sentry Hut, lower shield pillows

Skier triggered wind slab on that failed on 6mm surface hoar 50cm down. Very planar 1F bed surface, wind affected zone. Slab was fist plus. Several skiers hit pillows, snow was too deep to traverse over to "diving board' pillow, so the feature was accessed from directly above on a 35* slope. Debris slowed on the island of safety and skier slowed enough to grab tree. Debris moved faster on either side of the terrain feature and could have had more consequence on a larger slope or with terrain traps present.
