Travel and Terrain Advice
Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
Wind slabs may be poorly bonded to the underlying crust.
A crust on the surface will help bind the snow together, but may make for tough travel conditions.
When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
