Snowpit Observations
More detailed information about the snowpack: 

It looks like the last storm missed the Mosquito flat area, but past Ruby lake there were increasing amount of fresh snow.  Above Mills lake was sinking in about 10" with snowshows, and above 12K feet the fresh snow was deeper than ice ax depth (not sure how much of that was wind transport).  Some signs of wind transport, and the snow was hard at the top of the col. Down the south side of the col the snow was wetter (soft, but not powder). Overall, the snow was stable along the route. Some recent signs of wet slides, and older crowns. Heard a cornice break off at some point, but could not identify where.
