Avalanche: Turnagain
Location: Seattle Ridge
Motorized side, was sticking in the flats and well out of big slopes and run outs and off any avalanche terrain to fit my objective for the day. General obs included more precip then predicted ended up being 3″-5″ overnight. Bounced around from 1k-1.5k Did not go on the uptrack and over.
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.
