Weak and thin snowpack observed on low and middle elevation terrain on the shady half of the compass in this zone. Not much of a slab currently, but this snowpack would not hold up well to significant, rapid loading.
Calm day with a few passing clouds. Considerably cooler than previous day.
Thin and weak snowpack on the north half of the compass here. Went looking to see if warm ambient air temperatures had significantly changed the upper snowpack in these areas. Found that the upper 20cm of the snowpack had gained a bit of strength (4F) but not nearly enough to consistently keep you out of the facets below, even with fatter skis. Despite lack of a significant slab, weak snow near the ground is still producing repeatable, unstable snowpack test scores. Given lack of a significant overlying slab I was expecting to see ECTNs or ECTXs. However, 2 out of 3 of my ECTs propagated with light to moderate force on a well defined layer of weak snow near the ground. CPSTs and PSTs propagated to end in the upper teens to mid 20sBased on observations in this drainage in December and January and the presence of large, easily identifiable SH at this interface (10cm off the ground) I suspect this layer was buried 12/7.
Layer Depth/Date: 12/7, down 60-70cm
Did not shade upper as I did not directly observe SH there, but suspect it exists on many upper elevation slopes. Even without SH, I'd imagine this interface could produce real-world results when loaded.
