Snowpit Observations
More detailed information about the snowpack: 

At noon today, I got my snowmobile hopelessly stuck, so whether I planned to or not I dug a pit.  On East face at about 9800 ft. Air temp 0C.   SH 90 cm with bushes underneath.  Foot penetration was about 70cm and felt hollow underneath.  I felt pack settling and saw some shooting cracks.  What was most alarming was the "sugar", 1-4mm facets  at ground level amongst the bushes.  Very Strong over Weak in this zone!!!  The top layer was about 20cm of very dense wind packed snow.  ECTN3 at 20cm.  The next layer was a bit less dense but more concerning as our result was ECTP11 at about 65cm.  All aspects, at all elevations, were extrememly wind affected, with some open areas and ridges completely stripped, especially south and west facing.  Overall, the large overnight temperature shift, the extreme winds, wind slabs, the hollow feel, and difficult travel ended our day prematurely.  Too many red flags for me.
