People could trigger slab avalanches of wind drifted snow if they venture onto exposed upper elevation slopes. It is always wise to avoid travel on steep slopes with obvious deposits of wind drifted snow.
- Wind drifts are often smooth and rounded looking, like lenses.
- Drifted snow is stiffer and more compacted than non-drifted snow, and hard drifts often produce hollow drum-like sounds when you walk on them.
- Freshly formed wind slabs can be quite sensitive and are often remotely triggered. Older, harder wind slabs can be very stubborn and may not release until you get well out on them, suddenly failing like a big mouse trap.
- Shooting cracks in drifted snow are a sure sign of instability.
- The snow is still so shallow in avalanche run-out zones that people could sustain serious injuries if they are caught and carried over rocks in even a small avalanche.
