Terrain and Travel Advice
- Fresh snow rests on a problematic persistent slab, don't let good riding lure you into complacency.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
Problems
Persistent Slabs
Several crusts are now being buried in our snowpack. The most concerning is the Feb 03 crust which has a sensitive layer of facets above it in many places. We suspect this layer will become more sensitive with the additional load.
Aspects: North, North East, East, North West.
Elevations: All elevations.
