Travel and Terrain Advice

  • Be alert to conditions that change with elevation.
  • Wind slabs may be poorly bonded to the underlying crust.
  • Keep in mind the crust offers an excellent bed surface for avalanches.
  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
