Avalanche Details

Large slab avalanche was spotted this morning on motorized side on Southeast aspect of Seattle Ridge. My guess is New/Old Snow Interface going down on the most recent BSH. Without getting a ton of information from it my guess is SS-N-R2-D2.5-I

I am sure this slide was spotted by many today, thought CNFAIC could use some closer photos.
