Clear skies slowly shifted to scattered in the afternoon. Calm aside from the very top of the high point at 5000ft. Temp at high point was 34F, 2000' was 41F. Crust on surface everywhere where we traveled, no snow available for transport.
Saw distant D2 avalanches (wet loose?) running on aprons below cliff bands on large peaks. One was near us, at just below our high point, E, 4850'. See photos.
Snowline began around 1500ft. It mainly consisted of moist melt forms. A soft crust was present on the surface- we had good edging and the snow was supportable on skis. There were many patches of open and flowing water up to about 3200'. Boot penetration averaged 20cm. Above 4000ft where dry snow was present before the atmospheric river, the snow was melt forms, although it was sticky, and not well transformed yet.
In pits we dug on north and south aspects at 4900ft we found a moist snowpack down to the Xmas crust, about a meter down. The snow just above the crust was just barely moist. We didn't find any layers that were particularly concerning at this time in the pits.
It's surprising how much snow has melted in the last few days. It's still possible to travel in moderately thick trees above 3000', but more ground vegetation and downed trees are getting exposed.
