Persistent weak layers buried 1.5' deep and 3+' deep are still a concern. Strong NW winds were moving snow at many elevations but especially up high.
Wind direction/speed above was based on watching snow move at ridge level. S-1 most of the time we were out, with a few periods of S1 before noon.

Visibility was generally poor
Low elevations to the low/mid-transition: Easy to punch sled track through slab into 12/11 facets below. Depth to 12/11 was around 60-80cm.
Mid elevations were more supportable riding and it was harder to punch track into deeper facets.
8600', W: HS 150cm. ~12cm HN24. 1/27 was 45cm down and presented as thin layer of FCsf with small shards of SH. Pit wall presented a fairly distinct stripe. ECTP21. 12/11 was 105cm down and was 4F FC. ECTX. 12/11 layer strengthening slightly but still presenting poor structure.
Layer Depth/Date: 45cm, 80-105cm
Weak Layer(s): Jan 27, 2021 (FCsf) Dec 11, 2020 (FCsf)
Comments: Rose painted according to observed terrain. ECTP on 1/27. 12/11 could be considered a deep slab, especially at mid-elevations and above.
We avoided avalanche terrain
