Surprisingly few clouds until later in the afternoon when a high cloud layer moved in. Calm winds with temps staying below freezing.
Toured to the base of Eddies headwall and stopped to dig a pit at 2000′ on a NW aspect.

Large surface hoar at lower elevations, especially in the trees up to about 2000'. Mostly 6" of new snow on the surface with a 0.5-1" wind crust on more prominent features.
We dug one pit at 2000' on a NW aspect. The two layers that seemed most concerning are the 2/15 buried surface hoar, which was about 10" deep (25 cm), and the 2/5 facets, which were about 18" (45 cm) deep. The 2/15 BSH layer did not have propagation in our extended column test (ECT N 22). The 2/5 facets did have propagation in our extended column test, which is a sign that it could produce an avalanche and that is could be triggerable by a person (ECT P 28).
