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

Temps in teens, steady winds 5-10mph, gusts to 15mph. Snowing lightly all day. Not enough wind to fill in tracks midday but winds increased after our last run.

Snow surface

About 8-10” new low density snow on top of tincan common bowl.

Snowpack

Informal stability tests including hand shears / quick pits produced showed good stability and bonding. Lots of slope traversing and jumping produced no collapses. Only thing we got to go was a small soft slab in dog bowl. However - kept angles moderate and didn’t go out on anything steeper than 30.
