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

Obscured Skies until the afternoon, then some partial clearing and a little bit of sun. Light variable winds with a few gusts along the ridge from the east to around 10mph. Temperatures were in the mid 20s F.

Snow surface

3-4” new snow from today.
Below this, around 5-10” of soft settled powder over firm snow (old wind affected surface).


Snow pit at 3,000’ on W aspect.
Snow depth 3 meters. Wind loaded location.

CTX - no weakness found in top 120 cm. The stellar interface responsible for the warm-up bowl avalanche was 80cm (32”) below the surface and was bonded. As were any new wind slabs above that. Photo of pit shows 3-4” new snow from today with over a meter of pencil hard snow below.
