Observations

Made a valiant effort to find some skiable snow today on North facing terrain without much success...

Weather was clear, calm-ish, and well above freezing with temps soaring into the upper 40s.

Evidence of the 12/2 wind event is everywhere with duff/ tree debris strewn about below treeline and wind-stiffened snow on open slopes on all aspects at and above treeline.

I observed wet snow and rollerballing on East facing slopes at treeline in the morning that appeared to have little-to-no overnight freeze. I did not travel on South or West facing slopes but I imagine they got baked today.

I dug a study pit at 5800 where HS was 115-135. Saw some small facets above and below the crust from 11/17 rain, which is now ~10cm thick (photo). The top layer still appears well bonded to the crust and an ECT failed to produce any results.

Watch out for creeks and vegetation starting to bare out in drainages (see photo)
