Overcast, snowing lightly by end of day

Snow surface

Hand shears easy at 1400' Found BSH imbedded in NSF 20cm down and just above the Jan 23rd MF crust. Ski pen to this crust at low elevations.
Found BSH again about 30 cm down about 1500'. Didn't find BSH above that.
Lost MF crust by 1700'. Hit wind affect in some locations at about 1700'.
Good skiing alternated with pockets of dust (5-10cm) new snow/facets over hard windslab

Snowpack

Snowpit at 2700'
HS over 300 cm Loaded spot,

5 cm New snow-facets over
15 cm pencil hard windslab over
4 finger facets
EXTP 17 under the windslab
Got no results from several older windslabs deeper in the pack
Filling in pit I was able to produce multiple 3-4' shooting cracks on this layer (once it had the supportive strength cut out of the bottom)
Slab felt stubborn but potentially reactive in the right place.
