Snowpit Observations
More detailed information about the snowpack: 

Skinned up from the end of Old Mammoth Rd.  (Enough coverage to skin up, and ski all the way down, but bottom few hundered feet are very shallow, skiing thru bushes and easy to tag a rock...but better than it has been all year!  Above 9000' coverage was quite decent, and snow quality very good.)

No obvious red flags.  No shooting cracks / whoomphing.  Above 9600' there was a variable patchy thin dense wind crust in slightly more exposed areas up to ~1" thick with 3-4" of soft snow ontop, which failed easily with hand pit tests (failing just under thin wind crust, and ontop of fist hard faceted snow).  Test pit dug ~100' below ridgetop, see attached profile.  Only failure was an ECT test that failed with easy force but did not propogate under a near surface wind crust, but in this location the underlying snow was decomping precip particles.  Strong temperature gradient in upper 50cm of snowpack.  No failures in the lower old snow/facets in this rather deep snow deposit location.   

Calm winds, except for some light southerly gusts over ridgetop.  No visible snow transport today anywhere.  No signs of any recent avalanche activity.  Rather chilly still today, -2.5deg C at 2pm at 9800'.
