Unstable slabs of wind drifted snow are the primary concern today, particularly on steep, northerly aspects. The danger is greatest above treeline, and steep, wind drifted slopes should be avoided. Even a small avalanche can be devastating in consequential terrain. Look for slopes that have a smooth, rounded, or pillowy appearance.
