Comments
Speculating a small cornice fell last night and triggered a D1 pocket on the silver fork headwall. Didn't propagate much wider than the little path noted in red in the photo, just gouged into DDL facets. Hummocky snow surface in the flats to lookers left might've been a previous, wider slide off the headwall but was difficult to determine due to poor lighting. Otherwise, I experienced two small collapses on a pre-established skinner out of West Bowl.
