Remote triggered a wind slab avalanche on the southwest aspect of Observation Sub Peak from above and one “gully” to skiers left. Propagated thin to thick and into immediate lee of wind lip that existed along the ridge, followed the wind lip down the ridge, and initiated a wind slab avalanche taking out most of the face sliding on facets to ground. Our party was investigating the face for wind slab and had one member probing for slabs while the other two members remained on rock in a safe zone. Luckily no one was caught and it did not propagate into our position. We took the ridge back down on foot, and skied the glades/trees back to the road.
