Observation: Turnagain

Location: Eddies

Route & General Observations

Toured to the base of Eddies headwall and stopped to dig a pit at 2000′ on a NW aspect.

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

Surprisingly few clouds until later in the afternoon when a high cloud layer moved in. Calm winds with temps staying below freezing.

Snow surface

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).
