Comments
Photo 1. Stable snow beneath a pair of knife-strength melt-freeze crusts capped with today's storm snow. Travel on steep slopes was rough where the wind had scoured down to the crust. Photo 2. Still rotten down low. Photo 3. Sugar is bad for you. Photo 4. Persistent slabs and cornice falls onto wind slabs aren't out of the question on steep slopes. Conditions are pretty benign at moderate angles, but low probability, high consequence avalanches definitely aren't out of the question on steep slopes.
