Snowpit Observations
More detailed information about the snowpack: 

Toured from end of Old Mammoth Rd up to Lake Mary, along x-country tracks to Lake George, Up to Red Cone Bowl, and back.

-Enough coverage on rd to ski/skin whole way (a couple avoideable bare spots).  ~8"+/- of supportable snow at Lake George level.  Up to 1.5ft of snow depending on wind deposition at higher elevations.  Plenty of subsurface rocks and obstacles to hit from Lake George to top of Redcone bowl, scraped 20+ rocks on way down (snow quality for skiing though quite good).  In Redcone Bowl proper coverage is fairly good, and many people have been skiing this ...  caution still advised.  

-No evidence of recent avalanche activity, plenty of evidence of strong winds.  Upper portion of West facing slope stripped to ice.  Pit "sawed" on this slope (couldn't even probe past a few cm down) revealed 30cm of alternating layers of K+ to P+ hardness ice to the ground.  See attached photo with knife.  North facing slope much better conditions, varying from powder to firm windboard.  See attached pit profile for pit dug ~100ft below ridgeline.  Of note is that the presence of the concerning 10cm deep Fist hard facet layer below the 50cm of new snow deposiiton from the latest storm varied greatly even within the meter wide pit I dug.  CT tests failed with moderate force and rough shear quality, ECT test failed with hard force and barely propogated past a shovel width, with very rough shear quality.  Below the new snow was alternating layers of ice layers and facet layers.  Not too concerning now at present, but will be monitoring closely how these layers evolve and metamorphize, especially after addition of future snow loads.  

Greatest concern at moment is low-tide early season obstacles!  In steeper higher elevation terrain, slide for life conditions could exist in areas that have been windswept.
