Snowpit Observations
More detailed information about the snowpack: 

Today as we left the Lake Mary TH at 1035, we were able to use a test slope to get a newly formed wind slab to react very easily with the weight of a skier (see pic and video).  HS near this location was 75cm's, pen boot was 20cm's and pen ski was 10cm's.  At 1204 on a NW aspect at 9,270' above the Lake George Cabins, the HS was 140cm's, HSN was 38cm's, pen ski was 40cm's, pen boot was 68cm's and the Tsurf was -4.5C.  Surface snow was made up of 1-2mm graupel and .5mm stellars.  The skiing on a NW aspect in the Lake George Trees was very enjoyable.  I might even venture to say the best I've experienced in 2020!  We found no wind slab on the slope that we skied, but did encounter very small loose dry sloughs in small steep terrain features.

It's skiing great out there.  The trick is to keep out of harms way.  ESAC can help.

More detailed information about the weather: 

Today was a chilly and blustery day in the hills for the most part.  When we got to the TH at 1035, winds were strong out of the SW, with extreme gust and this would remain the case all day except in the most sheltered locations.  The sky started out broken in the AM, but became obscured in the PM as the snow intensity also picked up.  The intensity of snowfall was S-1 for most of our tour, but became S2 as we were finishing our tour around 1430.  The warmest air temp I recorded was -2C at 1119, and the coldest was -4C at 1204.
