Mountains 101 is a broad and integrated overview of the mountain world. This 12-lesson course covers an interdisciplinary field of study focusing on the physical, biological, and human dimensions of mountain places in Alberta, Canada, and around the world. Specifically, we'll study the geological origins of mountains, how they’re built-up and worn-down over time; we’ll learn about their importance for biodiversity and water cycles, globally and locally; we’ll explore their cultural significance to societies around the globe, and how that relationship has evolved over time; and we’ll learn how mountains are used, how they’re protected, and how today they’re experiencing rapid change in a warming climate. At the end of each lesson, Mountains 101 will also provide learners with some smart tricks -- Tech Tips -- to safely enjoy time in the high alpine environment: from how to pick the best footwear for hiking to making smart decisions in avalanche terrain. We’ll be delivering your online lessons from valley bottoms to mountaintops, from museums and labs, to alpine huts and other spectacular alpine sites, and we’ll do so with the help of a whole host of experts. We invite you to join us for this online adventure! The mountains are calling...

Lesson 8: Hazards

Mountain hazards are the focus of Lesson 8, specifically snow avalanches, landslides, and volcanoes. We will examine the physical processes that lead to instability in mountain landscapes and consider how risks associated with hazards can be managed.

Last time, we started the conversation about winter hazard and

this tech tip will expand on this topic.

Avalanches are the biggest hazards associated with winter mountain travels.

Through this lesson, you've learned the anatomy of avalanches,

now I'd like to tell you how to best avoid them.

There are five key things to remember,

to stack the odds in your favor, if you're in avalanche terrain.

Get the gear, get the training, get the forecast,

get the picture and get out of harm’s way.

Let's break each of these concepts down.

Get the gear. Everyone heading into

avalanche terrain needs to carry a full complement of rescue gear.

This includes, an avalanche transceiver, a probe and a shovel as an absolute minimum.

In the event of a burial, the transceiver gets you close to the victim,

the probe finds them and the shovel is what gets them out.

There's now strong evidence to support the value of avalanche airbag backpacks in

reducing the chance of burial.

And wearing a helmet will protect your head from trauma if you're caught.

Get the training.

Carrying rescue gear lacks effectiveness if you don't know how to use it.

Taking an avalanche skills training course will not only give you the basic skills to

use the gear properly, but

you'll also learn about what terrain to seek out and what to avoid.

Take a course and then practice what you've learned.

Get the forecast. Many of the popular areas for

winter recreation have an avalanche forecast for the region.

Public avalanche forecasters are the pros, they do their utmost to provide you

with the best possible info about what you may encounter on your adventure.

Get the picture. Be aware, eyes open,

ears perked trying to see, hear and feel what the mountains are telling us.

Look for recent avalanches, listen for

cracking or woomphing that's taking place around you.

These signs indicate of the failure of weak layers in the snowpack.

Be aware of recent storm snow, wind loading, or signs of rapid thawing.

The mountains often give us clues that foreshadow the potential

hazards we may be exposed to, so make sure you're open to the information.

At the most basic level, be aware of terrain steepness.

Remember that avalanches predominately occur on slopes over 30 degrees.

Get out of harm's way.

Make sound travel decisions while you're out in avalanche terrain.

It's best to avoid suspect slopes and terrain to begin with.

Don't regroup in avalanche paths or run out zones.

The less time you spend exposed, the better.

Avalanche safety can seem overwhelming to new winter travelers, but

by breaking things down into more manageable components,

it's easier to wrap your head around.

With some training and practice,

winter can be a spectacular time to explore the mountains.
