Noted a soft slab in Depth Hoar bowl that appeared to start as maybe 6" wind slab. As it ran, it appeared to entrain a good amount of snow, leaving a decent debris pile above the small trees towards the bottom of the slope. We couldn't see if it stepped down or not but the size of debris relative to the initial avalanche suggests this could have happened. The small wind slab was also quite wide and extended quite a way along the ridge line. Cornices were quite large in this area so the avalanche could have been triggered by falling cornice or just wind overloading the new snow. I'd estimate it as SS-N-D2-R2. I wasn't able to get a good photo of this particular avalanche but photos in the Yellowjack observation are representative.
