Sketchy video out of Washington State where a snowmobiler out for day of riding at White Pass in the Cascade Range triggered an avalanche the moment he turned around after a hill climb through fresh snow. The rider deployed his avalanche airbag backpack and managed to not get fully buried while his riding partner outran the slide.
While the walkie talkie conversation after the slide seemed jovial, avalanche safety is no laughing matter and this incident could have easily ended in tragedy. Learn more about avalanche safety below.
International Snowmobile Manufacturers Association (ISMA) Avalanche Safety:
Mountain riding is a fast growing activity for North American snowmobilers. With spectacular mountain terrains comes the added safety concern of avalanches. You can minimize your risk by taking an avalanche awareness course and carrying the proper equipment. If you don’t live in the mountains, but plan to ride there occasionally, you should prepare yourself before leaving. Here is some general advice and mountain riding pointers:
- Temperature inversions, rain and sun exposure can rapidly change conditions and trigger avalanches—snow loses strength as it warms.
- Avalanche bulletins cover large regions and describe the general conditions. Local variation is common and snowmobilers must remain vigilant in their analysis of the immediate conditions while riding.
- Always check the avalanche bulletin for your region before you go riding.
- Most avalanches occur in steep slopes of 30-60 degrees. Don’t park at the bottom of these slopes.
- If high-marking, go one at a time, with everyone else watching from a safe spot away from the potential avalanche run-out area.
- If someone gets stuck on a steep slope, give them time to free their sled. Adding another snowmobile to the slope could start an avalanche.
- Always wear an avalanche transceiver—and practice using it. Carry a shovel and probe in a small backpack. Your best chance of a successful rescue is if it’s done within your own party. There’s no time to seek outside help.
- “Fixation” on specific routes can lead to trouble—be open minded, well researched with options, and willing to retreat to try again another day.
- Please respect other park users in popular locations.
- Have fun and enjoy the beautiful mountain scenery!
- Take an avalanche class. These are available online and through various books and videos. But, it’s best to take a multi-day course on the snow.
