Estimating size at D1.5 or D2 - debris was blown in. Estimated depth, but I could see it from over a mile away in mediocre light. High probability it was a natural slide, but I can't say for sure that no one was out near there today. It could have been triggered by a sluff coming off the rocks, or a piece of cornice falling onto the slope? Crown indicated a very soft slab, either wind slab or storm slab. I chose storm slab, but this slope was probably wind affected (based on the obvious plumes still coming over the ridge in the photo).
