Signs of Unstable Snow

None reported

Observations

Snowpack was dust over extremely stout crust with larger facets underneath under treeline, and deeper powder near/above treeline. Snowshoes got purchase, but didn't sink in, whereas booting resulted in a few inch posthole.
Our party didn't see wet loose issues, but we didn't seek out affected slopes. We also avoided going up wind affected slopes, but we also traveled on fairly aggressive slopes..
The wind effect was variable, but the cornice overhangs were over the north side of. the summit ridge.
Crampons were a must for the descent down the hill. An ice axe was extremely helpful.

Media

Demo of snowshoe penetration along west summit ridge (~5.7k').
Example cornice with Old Baldy (note cornice along the north side or the east ridge) in the background.
Smallish cornices on north side of ridge; some appeared to have failed in the distant past.
Example wind drift around trees on south side of west summit ridge (~5.5k', IIRC).
