Warm, sunny day but felt like wet snow problems would have been fairly isolated. Despite (seemingly) good melt-freeze cycles, conditions on solar aspects have yet to fully transition to corn.

Snowpack Observations
Snowpack obs are from 1200-1430. All sun-exposed aspects we encountered were transitional and surfaces had not yet become fully corn-like. Conditions remained fairly ski supportable (i.e. not punching through into mush below) but were still marginal skiing. Felt like you would have to go looking for a wet snow problem - like pushing on a steep, rocky, solar slope late in the afternoon.
@9300', SW, ~25*, 13:45 (see photo): HS averaged 125cm. Surface was wet but still ski supportable. Evidence of water percolation in the top 30-40cm of the snowpack. Entire snowpack was moist but low water content except for surface layer. Depth to 1/27 was 60cm, to 12/11 was 100cm. ECTX even with hard loading. Prying the column off failed at 12/11 - no other shears occurred. 12/11 was moist and becoming discontinuous - some portions of the layer are still quite weak, while other "clumps" had bonded together.
