A few photos and some field observations from Rohr Ridge. Thanks to Jay Audenart for the information.

We were up there on March 8th in the afternoon, skinning up the ridge there is a point where you can first look into a NW facing chute and into "Stellar Bowl". Seeing a large amount of debris I originally thought the stellar bowl had ripped out as I have seen before (2009?). But upon getting in to ridge top found the stellar bowl line was intact (lots of wind loading and big terrain-trap wind lips - did not ski),  skirted around it to the small lake mid way in the bowl. Skied to the slide where crown was from 50 to 180 cm. Bullet hard bed surface underneath. Mid Feb layer? I suspect (and I think you can tell from the photos) it was a cornice failure that caused the slide. It was warm the previous days and have since read on the CAA  south coast bulletin of reported cornice failures from that period. I think the slide emphasized to me a pretty good "tipping point" example!
