10cm of snow fell at 5000ft overnight. Snowline was approximately 3500ft. Until noon there was a morning lull with overcast skies, minimal wind and no precipitation. Heavily rimed snow and wind rapidly set in at about 1pm. By 2pm large, fluffy and moist snowflakes were falling at a rate of about S3 at 5000ft, whereas moderate rain fell beneath ~3500ft. It remained gusty through when we left at 3:30.
We saw two small avalanches at a distance. They started as point releases in the new snow. One was on a steep SW slope at 5000ft above the Damfino Trailhead area. Another was on a northerly aspect at 5000ft.
New snow was heavily wind-affected above 5000ft, with some areas stripped back to the old snow (crust) surface. Only a few feet away we found drifts up to 25cm with obvious slab qualities.
The new snow was moist and heavy, especially where it was drifted. There were easy failures within the new snow layer in wind-loaded spots, but in other areas there was no failure plane within the new layer or at the new/old interface.
In several quick pits we found extremely variable old crust layers, and old runnels hidden by the new snow. In one location we found a thick 30cm crust, while in a few others there were thinner layers (5-10cm). The thinner crust layers had large looser and moist melt forms between them, and were 1 finger hardness or harder.
