Avalanche Awareness

  • What are avalanches? - Avalanches are rapid flows of snow down a slope.
  • Causes: Snowpack instability, weather conditions, and human activity.
  • Signs of danger: Recent avalanches, cracking sounds, and visible weak layers.
  • Stay safe: Educate yourself, carry essential gear, and travel with a partner.

Multiple Choice

What are some signs of danger when it comes to avalanches?

1

Snowpack instability, weather conditions, and human activity

2

Recent avalanches, cracking sounds, and visible weak layers

3

Educate yourself, carry essential gear, and travel with a partner

4

Rapid flows of snow down a slope

Avalanche Warning Signs

  • Recent avalanches: Indicates unstable snowpack
  • Cracking sounds: Sign of weak layers
  • Visible weak layers: Dangerous snow conditions

5

Avalanche Causes

  • Weather conditions: Heavy snowfall, strong winds, and rapid temperature changes can trigger avalanches.
  • Slope steepness: Steeper slopes are more prone to avalanches.
  • Snowpack instability: Weak layers within the snowpack can collapse, leading to avalanches.
  • Human activity: Skiing, snowboarding, and other activities can trigger avalanches.

Multiple Choice

What are some factors that can trigger avalanches?

1

Heavy snowfall and strong winds

2

Steep slopes and rapid temperature changes

3

Weak layers within the snowpack

4

Skiing and snowboarding

7

Avalanche Triggers

Did you know? Heavy snowfall and strong winds are two major factors that can trigger avalanches. Other factors include steep slopes and rapid temperature changes, as well as weak layers within the snowpack. Skiing and snowboarding, however, do not directly trigger avalanches.

Avalanche Awareness

  • Signs of an Avalanche:
  • Cracking or collapsing snow
  • Recent avalanche activity
  • Unusual snowpack conditions
  • Whumpfing sounds
  • Visible cracks in the snow

9

Multiple Choice

Which of the following is a sign of an avalanche?

1

Cracking or collapsing snow

2

Recent earthquake activity

3

Unusual rain conditions

4

Whistling sounds

10

Sign of an Avalanche

  • Cracking or collapsing snow: This is a clear indication that an avalanche may occur. The weight of the snow causes it to fracture and collapse, leading to a dangerous slide.

11

Avalanche Safety Tips

  • Stay informed: Check avalanche forecasts and weather conditions regularly.
  • Carry essential gear: Always have a beacon, shovel, and probe.
  • Travel with a partner: Never go alone.
  • Know the signs: Watch for cracking snow, recent avalanches, and unstable slopes.
  • Practice rescue techniques: Take an avalanche safety course and practice using your gear.
