Avalanche Safety and Awareness

The video discusses the deadly avalanche season in Colorado, highlighting the sensitivity of the snowpack and the role of weather in triggering avalanches. It explores the use of dendrochronology to study avalanche history and considers the potential impact of climate change. The video also covers methods to reduce avalanche fatalities through active mitigation and provides safety tips for backcountry skiers and snowboarders.

What has contributed to the increased avalanche fatalities in Colorado this season?

• Sensitive and weak snowpack

• Warmer temperatures

• Increased snowfall

• Thicker snowpack

Which type of avalanche is considered the most deadly in North America?

• Loose snow avalanche

• Ice avalanche

• Dry slab avalanche

• Wet slab avalanche

What scientific method is used to study past avalanche events by examining tree rings?

• Meteorology

• Seismology

• Dendrochronology

• Geology

How does climate change potentially impact avalanches?

• By increasing snowfall

• By altering weather patterns

• By reducing snowpack sensitivity

• By decreasing avalanche frequency

What is a common method used in North America to mitigate avalanche risks?

• Building barriers

• Using explosives for controlled avalanches

• Planting trees

• Reducing skiing activities

What is the primary purpose of using explosives in avalanche control?

• To create new ski paths

• To clear snow from roads

• To protect wildlife

• To safely trigger avalanches

Why is it important for backcountry skiers to never be alone?

• To share equipment

• To have someone to take photos

• To reduce the risk of getting lost

• To ensure help is available in case of an avalanche

What is a crucial piece of equipment for avalanche safety?

• Ski poles

• Avalanche rescue transceiver

• Snow boots

• Sunglasses

What should you do if you find yourself caught in an avalanche?

• Remain still and wait for help

• Try to swim to the surface

• Backpedal and keep your head near the surface

• Dig a hole to hide

What is the most common cause of death in avalanches?

• Falling into crevasses

• Asphyxia

• Hypothermia

• Animal attacks
