More detailed information about the snowpack: 

15 to 20" of new snow with the storm from the last two day that was mostly supportable on skis.  In most areas the new snow fell on bare ground.  Above 10,000' on Northerly and shady aspects this new snow fell on 5 to 15cm of 1 to 3mm facets.  Where the new snow fell on the existing snow from 3 weeks ago we were getting whumphing and collapsing with shooting cracks. Visibility was limited so we weren't able to see any wind transport at ridgetops.   

Photo 1: Snowpit at about 12,000' on a North Aspect.  

Photo 2: Snowpit at 10,800' on a WNW Aspect.  This slope had a enough shade to preserve the snow that fell on October 28th

Photo 3:  Shooting cracks from a collapse we caused while traveling on a North Aspect around 11,500'
