Comments
Small slope triggered when approaching - this is one of the usual slopes skiers use to enter the canyon when exiting Bow Hut. Small (10cm) surface slab from overnight winds, stepped down to Dec 18 facet layer, then stepped down to Nov 12 crust. Debris pile minimal in canyon, however, had potential to use an individual into open water, of which there are many spots in canyon.
