    You must keep this basal layer on your radar as triggering is possible in some features, like approaching or moving between pitches on ice climbs. Be cautious in steep terrain if you find yourself standing on the surface and not wallowing in facets, that's the problem slab.

Terrain and Travel Advice

  • Use caution when approaching steep and rocky terrian.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
