Red Flags Comment
<p>Recent storm bonded very well and skied stable.</p>

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.

Instability Comment
<p>Nuking snow and wind from 8000' upward.</p> <p>The November facets are still there on NW/N/NE, although under six to seven feet of snow in depositional areas.</p>

What the wind hadn't jacked was in good shape and filling in all AM. What the wind had jacked was stripped to the ground in places or forming nice sastrugi and waves.
