Points saillants

Avoid steep terrain where a stiffer slab overlies a weak facetted base (wind loaded features are prime suspects).

Triggering a Deep Persistent Slab avalanche remains our main concern.

    A variety of crusts with facets above and below exist at the bottom of the snowpack. These layers are going to be with us for a long time and pose a low probability, high consequence situation if triggered.
