Recreational Observation

Skinned up road, skied S. Meadows for a lap and headed up to ridgetop above the NW bowl. Descended to lake and meadows. Avoided avalanche terrain.

Feb. 5, 2017, 6 p.m. PST

Weather: Overcast skies, light snow, calm winds all day. Temps hovered at -5c.

Snowpack: Rightside up above the crust from 1/29, but very weak 4F to F. 1/29 freezing rain crust was down 70-90 cm in pits on N facing slopes at 5,200'. Column tests showed propensity for propagation (ETC P 22 down 70cm on small facets above the crust. PST 50/100 end on the same layer). We felt several whumphs near Skyline Lake.

Area Description: Skyline Ridge

Avalanches: A ski cut on a 40 degree small test slope fractured nearly 3 feet deep and across 50'. On a larger slope this would have easily been a D2 avalanche and would have buried a skier.
