In February 2012, pro skier Elyse Saugstad was carving through the slopes of the Cascade Mountains when a crack formed in the snowpack above her.
2
Before she was fully engulfed by a 5,000-ton wall of snow, Elyse heard “AVALANCHE!” just in time to react with a lifesaving maneuver.
3
So, how could she survive this crushing snow surge?
4
Avalanches are the rapid descension of snow, ice, rock, or a combination of these down a slope.
5
They can be destructive natural disasters and personal tragedies: in the United States alone, avalanches kill an average of 27 people annually.
6
These alpine nightmares don’t just awaken out of nowhere; they need three specific conditions.
7
First, the mountain needs to have the right slope, typically between 30 and 45 degrees.
8
This is shallow enough to allow snow to build up on the slope, yet steep enough to provide enough potential energy for movement.
9
Second, they typically need a layer of sturdy snow deposited over a weak or unstable layer, or what’s sometimes called “something over nothing.” Take the Cascade Mountain avalanche, where recent heavy storms deposited a nearly 1-meter-deep slab of fresh snow.
10
Below this sat a thin layer of surface hoar.
11
These are delicate, feathery ice crystals that form when water vapor in the air rapidly freezes on the surface of snow, almost like dew in the wintertime.
12
Finally, avalanches need a trigger, something to collapse the weak layer and put the snow in motion.
13
A trigger can be natural, such as heavy snowfall, strong winds, rainfall, or even other avalanches.
14
Or they can be human-caused, like the surface impact of skiers or snowmobilers.
15
Since fractures can propagate quickly through the snowpack, triggers can originate hundreds of meters away— upstream, downstream, or even adjacent to the avalanche’s path.
16
Once in motion, how quickly an avalanche moves depends on the slope’s steepness, its exposure or vegetation cover, terrain roughness, and the type and amount of snow involved.
17
For example, dry, light, and loosely bonded snow tends to travel fast, forming a powder cloud as it moves.
18
In contrast, wet snow avalanches, caused by water moving through the snowpack, travel more slowly but are much denser and can be particularly destructive.
19
Larger avalanches can travel more than 160 kilometers per hour, breaking trees, destroying buildings, and burying roadways.
20
In 1970, one particularly massive avalanche consisting of 50 to 100 million cubic meters of glacial ice, snow, mud, and rock reached speeds of over 300 kilometers per hour.
21
This avalanche proved to be the deadliest in history, engulfing an entire Peruvian town and killing 18,000 people.
22
Avalanches aren't always this large, but even smaller ones can be dangerous for anyone caught in their path.
23
As snow rushes downhill, it can behave like both a solid and a liquid, making its movement difficult to predict.
24
At the fastest-moving front, surface snow moves faster than the snow beneath, pulling victims deep into the snowpack and scattering them across wide areas, making rescue difficult.
25
Once an avalanche slows, the snow loses its fluid-like properties and compacts, leaving victims immobilized and unable to escape on their own.
26
For these reasons, the best way to survive an avalanche is to avoid one altogether.
27
Thankfully, at most ski resorts, parks, and even highways, avalanche workers mitigate risk by continuously monitoring the weather, stability of the snowpack, and human activity.
28
If a threat is detected, they'll close terrain and may even intentionally trigger a controlled avalanche with explosives or artillery.
29
However, there are regions where avalanche risk is not actively mitigated, known as the backcountry.
30
Here, you are responsible for managing your own risk.
31
Local avalanche centers provide avalanche forecasts, and anyone entering the backcountry should understand them, be properly trained, and carry essential rescue gear.
32
And ultimately, in high-hazard terrain, there's no way to completely eliminate risk.
33
The group at the Cascade Mountains consisted of highly experienced skiers.
34
Yet the area was very exposed, and following a large storm, the avalanche danger forecast was elevated.
35
In the end, three skiers lost their lives.
36
But not Elyse, as she was able to deploy an inflatable airbag.
37
These devices are imperfect and a last line of defense, yet can keep a victim closer to the surface, improving their chance of rescue should disaster strike.

About This Lesson

In this lesson, learners will practice their English listening and speaking skills through the compelling topic of avalanches and survival techniques. By engaging with this video featuring pro skier Elyse Saugstad, you will not only expand your vocabulary but also improve your comprehension of natural disasters and their repercussions. This lesson is particularly useful for those preparing for the IELTS, as it covers various relevant themes and vocabulary. By shadowing the speaker, you can effectively enhance your English pronunciation and speaking confidence.

Key Vocabulary & Phrases

  • Avalanche: A rapid descent of snow, ice, or rock down a slope.
  • Snowpack: A layer of snow accumulated on the ground or existing snow.
  • Trigger: An event that causes an avalanche, such as heavy snowfall or human activity.
  • Surface hoar: Delicate ice crystals that form on the surface of snow.
  • Mitigate: To make something less severe or serious, often through preventative measures.
  • Backcountry: Remote and undeveloped areas that are often not monitored for avalanche risk.
  • Airbag: A safety device that can be deployed to help keep a victim closer to the snow surface.
  • Fluid-like properties: Characteristics of snow that allow it to behave as both a solid and a liquid during an avalanche.

Practice Tips

To maximize your learning experience from this video and improve your English pronunciation, consider the following shadowing tips:

  • Listen Actively: Focus on the speaker’s tone and emotion as they discuss the dangers of avalanches. This can help you grasp the intensity of the topic.
  • Use Slow Playback: Start by playing the video at a slower speed. This will allow you to clearly hear each word and mimic the pronunciation more easily.
  • Repeat in Real-Time: While watching, pause the video at key phrases, and repeat them immediately. This technique will help you practice speaking fluently and naturally.
  • Record Yourself: After shadowing, record your voice and compare it to the video. This will help you identify areas for improvement for the IELTS speaking practice and improve your overall pronunciation.
  • Focus on Vocabulary: Pay special attention to the keywords listed above and practice using them in different sentences related to your own experiences or knowledge about avalanches.

Shadowing such engaging content not only entertains but also enhances your learning, making it an effective way to learn English with YouTube and develop your language skills.

What is the Shadowing Technique?

Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
