Snowpack Observations


With the recent snow total of 30 inches and blue skies we were interested in seeing how much snow was available mid-mountain. Knowing that the best turns were a few days ago, we ventured up the mountain to Lake Helen to see what was left. With minimal to zero wind we enjoyed a nice tour up Avy gulch. Our skin track had 6inches of penetration with a 1-2 inch crust layer. There was a lot of rock exposure due to the wind events high on the mountain which was noticeable on Green Butte ridge and Cassaval. The descent down was challenging due to the snow setting up due to the warming and sun crust layer. It seemed like a warm up for early spring conditions.
