Avalanche Summary

You might be able to trigger an avalanche on steep slopes if you find a cohesive layer of drifted snow that sits over weak snow below. This setup is most likely to be found on steep wind-affected slopes above treeline that face north, northeast, and east. Cracking and collapsing are signs of a slab over a weak layer, and if you observe these signs of instability, move to a lower-angle slope or choose terrain that faces south or west.
