Wind affected snow near the ridge


We dug at 2000'. HS: 110, S aspect, 18° slope. The upper layers of snowpack were upside down with 5 cm of heavier snow over a couple of layers (20 cm) of light fluffy snow. Aside from the top 5 cm the new snow was not acting like slab. The 12.1 crust facet sandwich was 80 cm down. One CT 26 on a small layer of faceted melt-forms below the thin upper layer of crust, 4 other CTs had no results and we both had ECTX in our pits. Basal facets were moist and stuck together.

We dug again at 2450'. HS: 140, W aspect, 15° slope. 12.1 crust was 80 cm down and seemed very stuck in the snowpack. CTs were not failing here and we both had ECTX. 30 cm of storm snow was right side up with no slab and no failures in Shovel Tilt tests. Winds picked up while we were digging with the stop skiff of snow starting to stiffen. Basal facets were 1F hard and stuck together.

We skinned to 3200'. As we progressed into more wind affected terrain the surface snow became a bit stiffer with a wind crust/small slab cracking while skinning. The skin track from the group ahead of us was mostly filled back in towards the ridge. Small cornice on the ridge was getting loaded with the winds.
