An avalanche may occur on a snow-covered slope when the strength of the snowpack cannot support the extra weight from a snowmobile, skier, rain, or heavy snowfall.

  • Learn to recognize and avoid avalanche terrain such as:
    • Areas where a slope is steeper than 30 degrees
    • Overhanging masses of snow or ice, often found on a ridge
    • Choosing a route that is close to dense timber, if possible
  • Observe good safety procedures, especially relating to avalanches.
    • Travel with a partner or in a group. Make sure each person has appropriate rescue gear, including a shovel and a transceiver or beeper.
    • Before crossing an unstable slope, look for possible escape routes should an avalanche occur.
