It is possible to trigger small avalanches of wind-drifted snow in exposed upper-elevation outlying terrain.
- Avoid and stay out from under stiffer pockets of recently drifted snow on steep slopes.
- Wind slabs may have formed or been cross-loaded in and around terrain features such as mid-slope roll-overs, gullies, under cliff bands, or sub-ridges.
- Suspect wind slabs are often chalky, rounded, and smooth, and they can sound hollow, like a drum. Shooting cracks and whumpfs or collapsing indicate instability.
Friday, we encountered hard, wind-textured snow in exposed upper-elevation terrain, a sign that pockets of wind-drifted snow may be resting on weaker, faceted snow in lee areas.
