- <p>Facets under CERC. 3-10cm thick 50-65 cm down (depending on pit) grauple layer showing varied results. </p>
NOTE Ryder and Sam (pit 1): 2 THERMOMETERS WERE USED THAT SHOWED SAME SURFACE TEMP BUT AFTER PROFILE CLEARLY DEPICT THEY WERE OUT OF CALIBRATION NULL TEMP PROFILE.
NOTE: KAITLIN AND JILL (pit 2) : OBSERVERS RECORDED TEMPURATURE -7C (150CM), -4C (110CM), -3C (90CM) BUT THEY DIDN'T ANOTATE IT IN SNOWPILOT BECAUSE THE TEMPS WERE THE SAME AS THE PREVIOUS ABOVE 10CM TEMP RECORDING. OOPS ALWAYS LEARNING
pit 1 (ryder) CTM at a grauple layer 65-75 cm down from snow surface. We were alarmed.
pit 1 (sam) CTN failed on shovel shear at same grauple layer depth. We were baffeled (Spatial Variability!)
Both observers and instructor were surprised and hopeful for an ECT with propagation but to no avail.
ECTX
Note: ECT full column also sheared clean with shovel shear after 30 taps
Pit 2 (Kaitlin and Jill) CTN, ECTX (sheared off after 30 taps at facets under CERC)

- <p>Poor snow structure continues at faceted snow layer under the Christmass Eve Rain Crust. Observers like keeping danger level moderate on northerly upper eleveation due to poor snowstructure and buried reactive grauple layer found.</p> <p>Watch for thinner snow pack on northerlies. We were curious about possibly triggering a slide on the burried grauple layer in isolated areas. </p>
Snowpit 1 with scoured wind texture on snow surface. Pit 1 location was located west of pit 2 and more northerly. Pit 2 observed surface snow better perserved on NW aspect.
