This SS-N-R2,D2-S looks to have been triggered by a WL slide from close to the ridgeline. You can see that the WL found a couple small pockets of new windslabs on its way to the apron before triggering the larger slide below the cliffs. Based on the location its possible that pooling graupel was the weak layer.
A closer look at the slab below the cliffs.
A look at one of the many WL slides that occurred on E-S aspects today with the first of the morning sun. This is on a SE aspect at 9800' in Roberts Horn. Not really that big, but when running through complex terrain, can add up to big debris piles.
