Snowpit Observations
More detailed information about the snowpack: 

Took advantage of the chair lifts today to access some undisturbed high elevation snow to assess possible wind slab instabilities and get a profile done before more snow and skiers and boarders shrawlp every square inch of the high Mtn.  One clear indication of stability was that yesterday the entire top of the Mtn was shot and hand charged with very minimal results.  We poked around along ridges and found some isolated thin subtle wind slabs up high, and some thin more pronounced ones mid slope on north facing terrain which were 1-2" thick at the most, ~4F+ hardness, plating out 5ft wide at the most.     

We dug a couple of pits just below the ridgeline in an undisturbed pocket below some rocks and found a mostly right-side-up consolidating snowpack, showing very little stability concern.  See attached profile.    

Based on our limited observations toay, we discussed our greatest potential concern in the backcountry right now to be small thin isolated wind slabs in consequential terain in the alpine, where a fall could have consequence.
