More detailed information about the snowpack: 

Toured up the sherwins to the ridgetop today to check on new snow stability and wind effects.  ~5" of light new snow at all elevations from this last minor storm that started mid-day yesterday.  No signs of wind anywhere except at the very ridgetop proper where there was some surface wind effects.  No denser snow deposits anywhere along the exposed westerly ridgeline on the ascent.  Wind was calm today everywhere except for the very ridgetop where it was light from the north.  No signs of instability except for minor sloughing in the steepest of terrain (see attached video).  Chilly, with air temp of -6.5°C at 10,000' at noon.  Snowfall was S1, a centimeter an hour at most during the late morning before it became even lighter after noon.   I would presume that southerly aspects in the alpine could be getting loaded just below ridgetops by the light northerly winds.

It's still a minefield up there with all the barely covered rocks and other obstacles.  Hit many.  Important to take it very slow.
