Three Sisters Area / 7250'
Ski or Snowboard
Sky Clear (<1/8)
Height of Snow (HS):
W / Light: 1-16 mph
We were on the look out for wind slabs after recent 8 inches or so of new snow and ice crust layers leftover from last weeks rain, no major red flags and no evidence of avalanche activity on the way up.
Dug a small pit at the top of our run:
Total snow level was 180cm.
Compression test yielded minimal gradual compression of new snow on top but NO buried fracture results all the way to 30 taps! Yay!
20 cm below the surface was a pencil-hard layer, 2 cm thick, and further down were more similarly hard and thin layers.
25cm below the surface was a layer of 1 finger hardness, about 5cm thick, which was solid enough to pick up and hold.
Again, all the varying layers seemed to be quite well bonded but I will be on the look out for spacial variability :)
