Poor Snowpack Structure

Even with winds did not observe any wind transport, seems as though we need higher winds to move around the heavy cold snow on norths. Still have poor structure. Dug two pits today. 9,400 N HS 110cm CTE7 SP down 20cm ECTN, CTM13 SC down 85cm on 20201211 FC/ECTX, FC near bottom of pack in this location were moist, gaining strength and rounded. Different story at 9,700' NW HS 115 ECTP24 down 85cm on 20201211 FC (large grained dry FC/DH 3-4mm), I was surprised to see propagation here due to the substantial amount of 1F-P hard slab protecting the weak layer. It seems as though in some places the depth of the PWL and the density of the slab may be bridging/protecting the weak layer from producing results from tapping (will be doing more PST's going forward). I did not observe results on the recently discussed upper pack PWL's that formed leading into the last two storms.
