Storm slabs have stabilized, mid-pack persistant weak layers unreactive to my tests but monsters in the basement still present
Overcast but warm, periods of very light snowfall but no accumulation. Crust on solar slopes from Sunday.
At mid to low elevs S -> W we have the usual soft slab with facets underneath, HS 60-80cm, ski pen depending on amount of wind press either 10cm or down to sage. No crusts in snowpack, sun crust on surface on exposed solars.
High elevs obviously wind affected from several directions, difficult to find a representative spot.
9700' NW HS 100cm
Basal facets/DH bottom 10cm, F hard, look well developed size >3mm and a very subtle crust/higher density and smaller facets on top. PST45/100 end on this layer.
Various windslabs in different degrees of faceting up to 70cm, 4f-K hardness, but no results in the interfaces between.
At 70cm 3cm FC (12/31?) under yet another 1F windslab some 5cm thick, no results on tests.
Above 70cm various generations of windslabs, RG F - 1F. ECTN at 80cm ininterface between wind slabs.
Wind has probably done too much work here to extrapolate much useful about mid pack PWL:s, but result on basal facets despite lack of crust is notable.
Layer Depth/Date: 11/26, 12/7, 12/31, 30-90cm
Basal facets was main concern where I was yesterday, but previous obs point to a variety of other layers, most notably 12/31 on more solar aspects at mid-high elevs. In general problem is confined to where wind has formed slabs, which is most upper elevs and a large part of exposed or sparsely treed mid elevs.
We avoided avalanche terrain wherever there was a chance the wind had got to the snow.Close
