Points saillants

If the snow is supportive then dig down and check the strength of the base of the snowpack. Previous wind stiffened snow over a weak base in shallow rocky terrain is the most likely scenario for skier or climber triggered avalanches at this time.

    Especially watch for previously wind effected snow over a weak faceted snowpack. A shallow snowpack and cold overnight temperatures will continue to weaken the existing strength of the snowpack.

Terrain and Travel Advice

  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
