Comments

Skier remote in Vista Bowl near the climbers right side of the convex feature on SE asp. Triggered while skinning by the arrival of the third skier in the flat area. Size 1. 12m wide, 40m tall. Crown varied 50-25cm. Fracture profile revealed 1-2mm facets on top of 5CM MFC. Slab was 4F wind pack. CTVE SP (failed when column fully isolated). Many whumpfs in same area. Only one slab pulled out though. Northerly slopes skiing just fine.
