Avalanche Safety Rundown
December 5, 2020
Avalanche danger is overlooked by many people in the backcountry, and for most of them, it’s not something that crosses their mind until it’s too late. I’m guilty as charged. I didn’t take a class until after a few close encounters with avalanches. It was something that I also overlooked for a long time. Finally, I decided it’s better to have the knowledge and not use it than to need knowledge and not have it.
There are a few factors that lead to higher avalanche danger, weather is a major one. Certain weather patterns will create a weak layer in the snowpack. For instance, warm weather precipitation followed by freezing temperatures with more precipitation is one occurrence to look out for. This will create a crystal-like layer of snow called facets that can collapse when more snow is layered on top.
Wind slabs are another factor to watch out for. With heavy winds, snow will build up on steep slopes creating various sized slabs that will slide under pressure or even slide with big enough sound waves. This is also how wind cornices form, a large amount of snow that overhangs on the crest of a slope. These can be just as dangerous if unstable.
Just being aware of the area you’re riding is one of the most important ways to stay safe in the mountains. If you’re riding near a big gully that slides often, it’s probably best to stay clear of it and avoid the runout zone. You always want to be looking for cracks or the crowns of old avalanches. Determine the slope of the area you want to ride in. As the slope angle decreases, there is a lesser chance an avalanche will occur.
It’s always good to refresh your knowledge before the season starts. Checking your gear, making sure your beacon works, that your airbag Cartridge has pressure, or your batteries are charged. Taking a class is always helpful, and being out in the field with someone who knows a lot, can also be useful in the long run. There’s not much more I can give you through an article, it’s up to you to take the next steps. Hopefully, it’s a killer snow season.
