More detailed information about the snowpack: 

Skiing was still pleasant in northerly trees, but quite wet and sticky in lower elevations. The snowpack is settling and adjusting rapidly from the warm spell we have had the past week, and especially since the major warm up of the past 3 days. The whole pack is gliding down slope and tree wells are opening up on the downhill side of large trees. I wanted to check on the status of our persistent slab conditions and if there was any residual surface hoar still to be found mid-pack. I did not find any surface hoar, and found the base of the snowpack to be rounding, and picking up strength under the compression of the overlying fat slab. The previous rounding facets at the base were significantly more rounded and bonded. The basal layer was 1 Finger to Pencil in hardness rather than the 4-Finger to Fist hardness we had been finding previously last week.

Although the lull in snow storms and warm weather hasn't been advantageous for short term skiing conditions, it is doing a good job on helping to strengthen and solidify our base snowpack. Its great  to have such good coverage and a sturdy snowpack built up during the cold part of  winter to hopefully withstand more big sierra dumps!

Another warm day with 100% overcast skies in the morning. There was heavier cloud banks over the Minarets and Silver Divide, but it did not appear to be precipitating out there. It was dead calm where I was travelling, and a little wet and dank feeling.
