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

Overcast and flat light in the morning. Mostly sunny in the afternoon. Temperatures starting in the 20s rising to high 30s in the afternoon. Light SSE wind. No Precip.

Snow surface

2-5cm of new snow in the past 48hrs on top of a 3-4cm thick knife hard crust. Surface snow started warming up in early afternoon. Ski and skinning conditions were dust-on-crust which made keeping an edge a challenge while touring up. No wind transport or other wind effects noticed except on highest ridge line.


We did not dig a snow pit or conduct formalized stability tests. Overall snowpack seemed locked in under the crust.
