Causes of Avalanches

Avalanches occur when a layer of snow on a slope breaks loose and slides down. The most common causes of avalanches are:

• Heavy snowfall: Significant snowfall can add weight to the snowpack, making it more likely to slide.
• Steep slopes: Slopes with an inclination of 30 degrees or more are more prone to avalanches.
• Wind: Strong winds can transport and accumulate snow, creating unstable conditions.
• Warm temperatures: Rising temperatures can melt the snowpack, weakening its structure.
• Human activity: Activities such as skiing or snowmobiling can trigger avalanches by disturbing the snowpack.

Avalanche Risk Assessment

Assessing avalanche risk is essential for safe travel in avalanche terrain. Several factors to consider include:

• Snowpack stability: This refers to the strength and cohesion of the snow layers.
• Weather conditions: The current and forecast weather conditions can influence snowpack stability.
• Slope angle: The steeper the slope, the higher the avalanche risk.
• Exposure to avalanches: Determine if your route exposes you to potential avalanche paths.

Avalanche Safety Equipment

When venturing into avalanche terrain, it is crucial to carry essential avalanche safety equipment, including:

• Avalanche beacon: A device that emits radio signals to locate you in case of an avalanche.
• Avalanche shovel: For digging out buried victims.
• Avalanche probe: A collapsible pole to search for buried victims.
• Personal flotation device: To keep you afloat in loose snow and prevent suffocation.

Avalanche Rescue

If you witness an avalanche, call for help immediately and provide the following information:

• Location of the avalanche
• Number of people involved
• Condition of the victims

Rescue efforts should be coordinated by trained professionals. Do not attempt to rescue victims on your own.

Avalanche Avoidance Techniques

To avoid avalanches, always:

• Plan your route carefully.
• Check the avalanche forecast.
• Carry avalanche safety equipment.
• Stay on marked trails.
• Be aware of potential avalanche terrain.
• Travel with a companion.
