Avalanche Details

Triggered very small soft slab/sluff on first steep rollover on eddies, did not run very far or step down to any suspect layers, seemed to be from snow the night/day of March 9/10 running on an apparently almost supportable crust from the March 8/9 storm.

Observer Comments

Many smaller (D1/D2) avalanches observed on sunny side, collapsing in alder/bush fields during the tour up to the base of Eddies, observed no red flags once we got onto the mountain. (other than avalanches on the other side of the valley)

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

Snowing hard, then sucker holes (which we timed just right)

Snow surface

Light Powder 8-10" where exposed to wind, 20+" in the trees

Snowpack

8-10" of power, then a quasi (buried) wind crust in open areas, that got hit by wind in the last storm. Facet layer about 4" thick below 36" from the last storm (pole poking tests). Did not dig a pit, had very little reaction on steep rolls for the first run, decided to ski something steeper on the second run.
