Observer Comments

We had cracking in small fresh windslabs that formed last night. No avalanching today, but we did see wet loose avalanches on steep aspects on Sunnyside, probably from the past couple days.

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

Clear changing to thin high cloud during the day. 20's into the mid 30's by afternoon. Light S wind.

Snow surface

Old powder with surface hoar to 3 mm on aspects with shade or less direct sun. More sunny aspects had a thin surface crust that became wet during the day. Near and above treeline the wind created small windslabs and scoured other areas.

Snowpack

We dug a pit on a NW aspect below 1000 feet in the forest. The snow height was 135cm. We had no propagation in ECT tests. There was a surface hoar layer up 60cm, a freezing rain crust up 70cm, and a surface hoar layer down 5cm, under the surface crust. See photo of pit wall.

We also dug at about 2000 feet on a north aspect. The snow height was 220cm. We found ECTN 21 (fracture initiation but no propagation) down 15cm on a 1cm surface hoar layer. This same surface hoar layer had shovel tilt hard results.
