Snowpit Observations
More detailed information about the snowpack: 

Shallow snow cover mid to lower elevations (12-20"). As you move into more exposed terrrain, snow depth is variable because of wind transport. Snow surface - .5 cm new, wind board, patches of faceted snow. Plenty of evidence of wind effect from New Years Day, elevated tracks in places. Foot penetration - 50cm. Wind westerly, blowing snow SW-W. Surface temp -12.2 C, Aspect N, Angle 27 degrees, Elevation 10320'. Lite Melt/Freeze Crust on Solar Aspects.

Stability Tests - CTM 2 X2 @ 143cm, CTE0 @ 143 (failed on isloation), CTM19, CTH20, CTM15, CTM 11 all at 20 cm facet layer. Deep persistent layer not currently active but may become overstressed by avalanche activity in the upper snowpack or with rapid loading resulting in failures stepping down deep into the snowpack. Will need to monitor with approaching system.
