Snow Characteristics Comments
HS 80cm / HST 28cm / HN24 15cm based on best guess from change in density and crystal type. Bottom 25 cm starting to see rounding and building some strength, 25 to 35 cm much weaker facet layer, 2-4mm with some larger chains. Consolidated old snow above this, providing a reasonable slab for propagation, with ECTP6 failing on the facet layer 25mm off the ground/55cm down from the top. Collapsing/long running rolling thunder walking around the meadow adjacent to pit.

Red Flags Comments
While near surface facets are beginning to heal/round and bond into a stronger layer, another, weaker layer of faceted snow just above that continues to provide a significant weak layer. A 40cm slab of consolidated old snow between the facet layer and new snow above allowed for lots of rolling thunder and propagation in pit tests.

Comments
Had an excellent day skiing FM100 easy listening powder on low angle mini golf slopes adjacent to the yurt. Snow surface generally supportable, keeping us off the deadfall lurking just below the shallow snowpack. Southerly slopes exhibiting slight zipper crust by the end of the day, after getting cooked throughout the afternoon. Hard to find a balance and the ideal line between wanting to stay off due north, and shallow south facing snow, but it's out there.
