Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Avoid freshly wind-loaded features, especially near ridge crests, rollovers, and in steep terrain.
  • Use ridges or ribs to avoid areas of wind-loaded snow.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
