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

Precipitation: Light snow with clearing early afternoon. So stoked not to have a single drop of rain!
Wind: Calm to light depending on locations.
Temperature: Hovering around freezing.

Snow surface

New storm snow accumulation 10-15cm. Quite moist & cohesive storm layer, simple snowball toss tests developed some rollerballs, but no wet slab or wet loose activity observed.
Boot penetration was ~70cm due to the wet surface snow.
Two groups found melt freeze crust in lower elevations.

Snowpack

Snowpack was "boring" in the top 100cm. Generally right side up, moist and isothermal.
Snow stability tests below treeline had no significant results (several CTN & ECTX on SE & W aspects).
HS:285cm
