Persistent weak layers in the top 2 feet of the snowpack are showing signs of having healed. The December facets near the base of the snowpack (4' deep in this area) are showing some signs of improvement, but you can't rule out trigger a deep slab avalanche on very steep, rocky, wind affected slopes. 3" of new snow and light to moderate winds did not produce a significant wind slab problem in this area. If you limited your travel to sheltered mid-elevation slopes, triggering an avalanche seems very unlikely.
Several periods of sputtery S-1 during the day, but very little accumulation. Winds were light along the somewhat sheltered ridge crest we topped out on, but we did not see much evidence of wind up higher.
@8000', flat: HS 140cm, 12/11 could be probed about 90-100cm down.
@8500', NE: HS 190cm. 1/27 barely discernible and produced no significant results in ECT, even with very hard hitting. 12/11 down 130-135cm, PST 55/135end.
@9000, SE: HS 155. Only looked at the top 80cm of the snowpack, targeting 1/27. 1/27 was visible in this pit as a strengthened FCsf layer. ECTX.

Comments: PST 55/135end. Rose indicates observed terrain.
We did not observe a wind slab problem. Shallower persistent weak layers (i.e. 1/27) showed no signs of still being an issue.
We traveled on small slopes approaching the mid-30s, and traveled quickly through runout zones.
