Date of Observation: 02/13/2017
Name: Evan Ross
Aspect: North East
Avalanches: Big roller balls on a few steep ENE slopes. Think these mostly fell out of trees rolling to larger size as the moved down the hill. These didn’t entrain any more snow. New snow to thick?
Debris piles below the east face of Gothic. Couldn’t see any slabs or crowns on the face, though light could have been better.
Weather: Sun poking through the clouds in the early morning, then overcast sky for the rest of the day. S1 snowfall began at about 4pm. Calm winds
Snowpack: Very little signs to instability, traveling across several steep slopes to 40 degrees. Snowpack was pasted in above 10,500ft with an inch or two of fluff form last night. Minimal sluffing in 40 degrees terrain. Above this elevation the 2/10 interface was down 25cm and dry with some graupel in the mix. No CT results on this layer or results while skiing. In the same area on a 35 degree slope, 1/19 SH was down 90cm. CT27 SP on the SH. SH is still 2-3mm tall but looks to be filled with rounded grains between the feathers.
Below 10,500ft the snowpack became very thick. Very northwest feeling shmooo. Bet it was still 0c through the new snow as observed in previous days down below the 1/10 interface that is moist, going on borderline wet for about 5cm. Hand pits produced more non-planner breaks. Ski tests showed no signs to instability.
