Incident

We triggered a size 1 slab avalanche yesterday on approach to Orion Falls, see pictures. We were traversing right beneath the climb when the first skier triggered the slope in a shallow thick to thin snowpack area, after cutting a small convex roll. The fracture propagated up and left from him, then left across the base of the climb and about 70m above us. 50m wide crown, 0-30cm, soft-medium slab. The 2 remaining skiers were caught by the slide and went for a short ride, 10-15m. Partial burials, one knee deep, second one to waist, both still standing upright when things stopped. That same slope had been skied the day before. Area around us was wind affected with numerous wind slabs.
