Calm and very warm in the late morning as the sun came out. Many rollerballs started coming down. Started seeing loose wet slides on solar aspects. Wind started to pick up around 2 pm. Snow transport visible at 9800 ft in Hemlocks. Rolling saltation mostly but some turbulent suspension as well. This wind started cooling the air temp and snow surface. 

Noticed 45 cm of new snow in Hemlocks in the center part of it. Hand shear easy at 45 cm. The bottom of the block and the underlying layer were covered with Graupel. Aspect N,9922 ft. A 3cm soft wind slab fell off the top of the hand shear block as it fell over.

Hand shear easy at 10'000. NW aspect, wind affected. 6 cm soft wind slab broke on in storm layer. Saw perfect Stellar crystals on layer underneath the soft wind slab. 

Skied Hemlocks on our first lap. Triggered loose dry slides at every turn. More snow became entrained and chased me as I skied ahead of it. D1, soft
