Wind slabs

Wind slabs are best managed by recognizing and avoiding areas where wind slabs have formed, until they have stabilized.

• Vary in size from small to medium.
• Occur on steeper lee and cross-loaded portions of slopes (typically 35+ degrees).
• Are often limited to specific terrain features such as lee ridge-tops.
• Can often be recognized by the appearance of the snow surface, changes in surface snow hardness, hollow, drum-like sounds and/or shooting cracks.
• Winds that vary in strength and direction can produce complex and unexpected wind slab patterns.
• Stabilize fairly soon, usually in a few days to a week.
