Comments:

SVHS Run called "Wapiti", which is a well defined and large avalanche path, but a somewhat stubborn slope angle. Start zone was heavily wind loaded, which is why the crown was nearly 2 meters deep. Generally a soft slab, but some hard slab blocks scoured the bed surface down to the ground in places.
