AVALANCHE SAFETY AND AWARENESS

COMMON PITFALLS OR ‘HEURISTIC TRAPS’

We’re all liable to fall into lazy, false or habitual ways of thinking, perhaps especially at moments of extreme fatigue or stress. As a climber, it is precisely at those moments that you’re at your most vulnerable.

The most common ‘heuristic traps’ can be categorised under the acronym FACETS (Familiarity, Acceptance, Consistency, Expert halo, Tracks, Social):

Familiarity

– if we are familiar with a particular area or route, and have not previously encountered any problems with it, we are likely to assume that it is safe, even when it is not.

Acceptance

– we all have a tendency to engage in activities that we think will get us noticed or accepted by people we like or respect. It’s natural to want to impress others in the group, and this may cause us to overlook warning signs.

Commitment

– we’ve come a long way, we often feel compelled to remain consistent and continue with the route, regardless of any warning signs we may encounter.

Expert halo

– we often place our trust in a group leader, and allow them to make critical decisions for the group, even if those decisions do not seem to us the most sensible.

Tracks

– “This pristine snow looks so good, there are no tracks on it.  I just have to ski, walk, climb it, and be the first one” This is about how we sometimes overvalue things that may be scarce.

Social

– sometimes in a group we feel social pressure not to be the one ‘making a fuss’, expressing our concern about the conditions or route choices that have been adopted by the group.

When you go out in the mountains, it’s important to be aware that we are all vulnerable to these ways of thinking. Always do your own preparation: research your route, and take note of the weather forecast. Trust in your own observations, and don’t be swayed by others who may seem more knowledgeable than you (it could just be bravado). Remember that you are never committed to a reckless course of action, no matter how far you’ve come.  You’re always free to change your route, or turn back. The mountain will be there tomorrow – make sure you are.

B.A.D. APPROACH

What can we do to minimise our vulnerability in an avalanche zone?

Take the B.A.D. approach (Before, Approach, During).

Before

– before we set off on our journey, we should review the weather forecast.  Check the snow/avalanche forecast.  Look at other people’s blogs (they may give details about conditions out on the mountains).  And study a map of the area, including any route(s) we intend to follow or avoid.

Approach

– on our approach we should observe the weather conditions – do they match the forecast, or are conditions proving unpredictable? We should look for signs of any recent avalanche activity, or instability. If possible, we should check the descent route too.

During

– we should constantly reassess the weather conditions for any change, and, as we travel through the snow.  We should be aware of any signs of instability. If there is any cause for concern, we should remember to be flexible and consider alternative routes.

OTHER CONSIDERATIONS:

Consider the history of the snowpack – look at the previous 7 days of weather and avalanche forecast before going out on a trip.  Sometimes, 7 days is not enough, you may have to look at the history of the snowpack from the beginning of the winter.  This depends on where you are in the world, and the weather conditions.

Approach conditions – as climbers we are very likely to approach a climb on a slope which is the perfect angle for avalanches.  So consider the avalanche conditions, and make sure you have alternatives to the route choice.

Snow conditions above the route – keep in mind that your route choice may be under an area that may be at risk of an avalanche, or you may be crossing the path of potential avalanche looming.  Avalanches are very often triggered by parties above.

Please consider all of the above topics when you go out in winter conditions, where avalanche safety and awareness are a must, whether going skiing, ski-touring, winter walking, mountaineering or climbing.

WINTER COURSES

The Scottish Avalanche Information Service (SAIS), have some great information available.  Regarding the decision-making process and the fundamental considerations of assessing avalanche hazards in the winter mountains. With the advice on their pages, together with the corresponding resources, you should be able to make better judgements on where and when to go.
