Quick report

We stepped into the cloud today in the WMR sidecountry. Freezing fog was widespread, and a subtle, mostly unnoticeable rime crust that formed through midday thickened and hardened as the day went on—unfortunately capping plenty of great powder underneath. We picked up 3–5 inches of new snow Tuesday into Wednesday. Stability was good and the fledgling snowpack appeared strong. Even when we prodded the snow on steep slopes and along the uptrack, it showed no signs of instability, and we saw no evidence of wind transport before the crust locked up the surface.

Our primary concern was the thin snow cover, even up high. Many obstacles are still exposed—or worse, lurking just below the surface. While the morning turns were generally good, we still bumped into plenty of shallowly buried hazards.

Very limited visibility with freezing fog all day, especially pronounced above 6000 feet. Graupel/rimed precipitation particles began falling in the mid-afternoon, which transitioned to snow as we descended towards the base of the mountain at 15:30. Winds were calm.

Snowpack

Ski penetration was through the new snow, approximately 12 cm. A surface rime crust was thin and barely noticeable at the beginning of the day, but thickened to 1 cm and became more stout and cohesive as the day progressed, as the freezing fog accreted onto the snow surface. We dug two snow pits above 6500 feet on east-northeast and northeast aspects. Pit structure was nearly identical, and we found 80-90 cm of total snow. The upper 50 cm or so of the snowpack all fell since last Monday, November 24th. 

The snowpack is generally right-side-up and resting on a stout refrozen base in the bottom 34 cm. Snowpack tests were unremarkable.
