Snowpack Summary
Up to 30 cm of wind affected snow is topped by a variably breakable crust caused by recent strong winds and above freezing temperatures. Moist snow lays beneath this. The trace new snow on Sunday was showing a good bond to this surface.
The mid and lower snowpack contains various old crusts and is generally well-settled and stable.

Terrain and Travel Advice
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
- A crust on the surface will help bind the snow together, but may make for tough travel conditions.
