Comments

Ski pen roughly 10cm; boot pen 60+ cm....demonstrating how the wet snow has yet to lock up; the new snow only insulated the rain saturated upper levels of the snowpack.  

Photos:

Class 2 cornice fall likely pulling out early this morning - 4' chunks of hard cornice...perhaps 100' wide.

Cornice laden ridgeline

The drive down Fairview canyon

Seems mostly stable with an eye toward cornice fall and wet activity -
