Observations

We observed wind scoured South/West ridge lines, and very large cornices off the ridges towards the North/Northeast. We skied multiple laps on 25-30 degree East aspects and the skiing was excellent. We knew the persistent layer existed before entering the terrain and decided to ski conservatively away from cornices, potential wind slabs, and steeper slopes.
