    Cold temperatures and additional snowfall the evening will increase the likelihood of dry loose avalanches in extreme terrain. Be aware of your overhead hazard and exposure to consequence.

  • Deep Persistent Slabs

    You must keep this basal layer on your radar as triggering is possible in isolated features, such as steep rocky terrain where you find yourself standing on the surface and not wallowing in facets, that's the problem slab.

  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
  • Be carefull around freshly wind loaded features.
