Upper Ten Mile

A clear calm cold day in the alpine of upper 10 Mile Fiord. New snow amounts ranged from 10 cm at Valley bottom, to 20-30 cm at 550m in upper valley. Deteriorating crusts underneath. Below ridgetop has seen little wind effect, with good overall coverage on all aspects. We were surprised by some recent slab avalanches on the North facing side of the valley, on high Alpine features. Possible cornice triggered. Some wind slab formation on the south facing rim of the valley, but seemed isolated to the windiest of start zones, disappearing quickly with elevation loss. We skied mellow start zones and low angle trees and had no instability issues. South Facing.
