Avalanche! Lessons From a Deadly 2011-2012 Winter Season

Last winter was the deadliest avalanche season in over a decade, with avalanches claiming the lives of 20 skiers and snowboarders across the United States.

It even outpaced the 2007-08 winter season, when 14 skiers and borders were swept up in avalanches and died.

A new report from Backcountry, called the Avy Bulletin, shed some light on the reasons for the uptick in avalanches and avalanche-related deaths.

According to the report, the 2011-2012 winter season was unusual in many of the states commonly thought of as winter-recreation states, like Colorado and Utah.

“States like Colorado and Utah had close to record-low snow years, leading to unstable, unusual and unpredictable snow packs,” according to the Avy Bulletin: Part 1, written by James Dillon. These precarious snow packs directly resulted in more avalanches.

In the bulletin, Dillon included his Q&A with Bruce Temper, director of the Utah Avalanche Center. Their discussion provides a lot of interesting information on last year’s avalanche conditions, media coverage of avalanche-related deaths, and plans for backcountry education. Temper talks about how they use YouTube and Vimeo for avalanche safety education. He also said they use Twitter for rapid-fire updates to alert skiers and boarders when conditions change or become hazardous. If you’re thinking about doing some backcountry recreation this winter, the Avy Bulletin is definitely worth the read. This is just the first of a three-part series published in Backcountry.

That said, here are some tips for how to maximize your safety while getting fresh tracks in the backcountry during the 2012-2013 winter season:

Take Avalanche Gear 

The Avalanche Danger Scale is a standard scale for measuring avalanche danger. It’s put out by the Colorado Avalanche Information Center. It goes as follows:
  • Green – safe avalanche conditions
  • Yellow – heightened avalanche conditions on specific terrain; evaluate snow and terrain carefully; human-triggered avalanches are possible
  • Orange – dangerous avalanche conditions; evaluate snowpack very carefully; human-triggered avalanches are likely to happen, and natural avalanches are possible.
  • Red – very dangerous avalanche conditions; travel in these areas is not recommended; all types of avalanches are likely; large and very large avalanches are likely.
  • Black – extreme avalanche danger; avoid all terrain; natural and human-triggered slides are certain; large to very large avalanches in many areas.
Know the Basics for Avalanche Survival
If you find yourself in a position where there may be avalanche danger, you should cross the area, or slope, one person at a time. Make sure that your clothing is tightly secured, but that your pack is loose (you will want to shuck it if tumbling in an avalanche, along with ski poles). Make sure your beacon is set to “transmit,” not receive.
If you are caught in an avalanche, yell as loud as possible, drop your poles and your pack to make yourself as light as possible. Use swimming motions in the snow, thrusting yourself upward toward the surface. If you are near the surface and the snow is packed too tightly for you to dig out, try to stick a limb through to the surface, so rescuers can find it.
If you are totally submerged in snow, the thing to focus on is creating an air pocket, since most avalanche deaths are caused by suffocation. This must be done immediately as the snow tends to pack and harden the longer you wait. Dig out a pocket around your face and head and begin punching through the snow. Keep your breathing steady, as you will need to preserve what air is available. For the same reason, you should avoid screaming until you can hear the rescuers.
