Snow Characteristics

Snow surface

Generally good skiing away from old ski tracks. Old faceted snow in upper 20cm of snowpack. Sun crusts on south aspect during morning. Upper 10cm of snow became wet by mid afternoon on steeper south aspects in some areas.

Snowpack

Fist hard first 20cm from surface, increasing hardness to 1 finger/pencil in mid pack, and lower 30-40cm of snow pack fist hard facets/depth hoar. Our primary layers of concern were buried surface hoar and basal facets.

Pit 1 @ 2000 ft, west aspect, 25* slope, and height of snow = 80 cm: ECTP 10 on buried surface hoar 30 cm from surface. Basal facets were not reactive in this pit.

Pit 2 @ 3300 ft, NE aspect, 25* slope, and height of snow = 85 cm: No buried surface hoar found. ECTP 22 on basal facets and depth hoar 50 cm from surface
