More detailed information about the snowpack: 

HST - 10" or so, snowing at 1-2" per hour while I was there.  There is a density inversion with the upper dense layer of HST overlaying yesterdays less dense snow.  Some cracking (1st photo) none of it shooting or propagating.  Most columns failed on or before isolation in depths ranging from 4-12”, very variable (2nd photo).  Of note they failed with a bit of a “pop”. The ones on flat terrain which I was able to isolate broke with a shear with an easy push or tap.  Inversion made travel a bit difficult.

Any other comments about the observation or links to outside pages that have more info on the observation: 

I was surprised by the lack of in your face signs of instability but I stayed in the trees and avoided any exposed areas.  I would not have felt comfortable skiing any open meadow with slopes approaching 35 degrees or so. 

I did cut one of the north facing road cuts on my exit.  The first cut resulted in sluffing of the upper 4-5”.  The 2nd cut resulted in a  8-10” thick, soft slab that did not propagate wider than my turn, once again, I expected more.

Without many obvious signs of instability, the hazard is a hard call, I would say considerable in this sheltered area.  I would expect High in wind affected/loaded areas.  I would also expect a good natural cycle in places due to the new load and wind.  The hazard will rise with the expected increase in temps.

Thanks to the folks who broke trail!
