SteadyBottom Line
A conservative mindset is still recommended while the persistent layer of buried surface remains. It is now loaded with 45 cm of snow was consistently producing results during our snowpack tests. There is still plenty of enjoyable skiing on mellow, low angle terrain.

Weather Summary
Cloud Cover:
Mostly SunnyTemperature:
-5 CWind:
Light , SWWe did not observe any new precipitation and temperatures ranged from 0 degrees Celsius to -5. Our winds were light to moderate out of the SW. There is roughly 15 cm of snow available for transport, but we did not observe as much blowing snow as yesterday.
Snowpack Observations
Snow height ranged from 170 to 220 cm depending on aspect between elevations 6000 and 6300 ft. Cracking and collapsing was observed but not widespread within the terrain. We saw an ECTP 21 down 45 cm on buried surface hoar that consisted of 2-3 cm grains. We also saw an ECTN 22 on that same layer and an RB4.
