Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Overcast, clearing to the South at end of day. Calm, Temps dropped considerable w/ the clearing.

Snow surface

20-25cm new snow and early facets over MF crust from Dec. 1 to about 2450' where the crust became thin enough to be unnoticeable.


At 2350' on a E aspect, I did a quick pit to check bonding to the Dec. 1 MF crust. The crust was degrading and friable with a thin layer of facets above it. The 25cm of snow above the weak layer/ crust combination consisted of about 10 cm new snow from the past few days along with early facets and was not cohesive enough to propagate a fracture in tests. CTN and ECTX

At 2690' on an E aspect, we found a fairly homogenous 90cm snowpack. We got no results on CTN, ECTX, and Deep tap tests. The Dec. 1 crust was less than a cm thick and barely noticeable at 65cm. There was a BSH layer at 35cm that we were only able pull out by pounding on a burp the baby test. The basal facets at 15cm were moist throughout the pit and did not fail in our stability tests.
