Quick Observation
Toured up the north ridge of Snowshed Mountain and dug a pit around 6800' on a southeast aspect today.
Descended the same route after skiing an East aspect at upper elevations.
Weather-
Skies: Mostly Cloudy
Temperature: Below freezing (25*-30*F)
Winds: Variable, 5-7mph
Dug a pit on a 32* aspect; shovel shear confirmed many weak layers, slabs within the upper portion of the snowpack. There was a crust (1cm thick/4F) from the recent rain event (1/18) with approximately 30cm of new snow atop it. This rain crust was supportable and much thicker below 5000'; hardly noticeable above 5000' while skinning or descending.
Conducted both CT's and ECT's, all with moderate results on or near this buried rain crust (30-35cm below surface). None of the ECT failures propagated and shears were inconsistent; the pit location did not harbor any recent windslabs.
I chose to ski sheltered terrain on a modest aspect. Recent windslabs were forming at ridgeline, although relatively unreactive with ski cuts.
