Snow showers (S-1 to S1) most of the day. No wind. Clouds in drainages.

Snowpack

4-10" of recent, low-density snow at surface all aspects at low and mid elevations. Stayed dry on all aspects thanks to cloud cover and cool temps. Lots of SAWS - snow available for wet slides. And lots of potential triggers, because most trees still holding snow in branches. Snowpack < 5000 feet ~ 1 m and unconsolidated. Would be easy for wet loose slides to gouge into this snow once it gets saturated. 

New snow sitting on harder, dry snow on shady aspects, and a 1-2 cm thick sun crust on steep, open sunny slopes. This crust was more widespread on slopes with a westerly tilt. It didn't affect skiing much.

Probing w pole at mid elevations indicated mid-January ice down ~100 cm.

Avalanche

Surface snow moved with turns on slopes > 35* but never got going far or fast, and stayed on surface.
