Bottom Line: The main avalanche concern is fresh drifts of snow. Be cautious of slopes where yesterday’s snow was drifted into thick, dense slabs. The best strategy is to avoid steep wind loaded slopes for a day or two, and then carefully assess them after that. Keep in mind, the most dangerous slopes are where these slabs formed over weak, sugary snow. These slabs on top of sugar will be unstable for longer and can be less predictable, large and very dangerous. Avoid steep slopes where you find soft, sugary snow under a cohesive, supportable slab.

  • We found a thick layer of surface hoar (1-2cm) on top of the snowpack at Lionhead Ridge on 11/24/20. Below that layer the snowpack was faceted and weak. This will be an unstable foundation for future storms. Photo: GNFAC

  • The BBWC (Bridger Bowl Wind Cloud) on Tuesday 10/27 accompanied 50-60 mph gusts. This strong wind drifted recent snow into slabs that could avalanche on steep slopes. Early season snow means we need to be thinking about and managing avalanche hazard when we travel in the mountains. Photo: GNFAC

  • Backcountry.com did a social media survey and found that many of us could use an avalanche class. Don't hesitate to sign up for one. Even a one-hour avalanche awareness class is a great place to start. Check out our Education Calendar for an expanding list of classes being offered in southwest Montana. Many are free.

  • By morning of October 11 most mountain ranges were white at the higher elevations. This picture of Saddle Peak was taken from Stone Creek up Bridger Canyon. About .6-.8" of precipitation fell throughout southwest Montana. The Fisher Creek Snotel outside of Cooke City shows 6" of snow fell at 9,100 feet. Only time will tell what melts and what sticks around, but it sure is a good sign! Photo: GNFAC

The Last Word

The Friends of the Avalanche Center are encouraging everyone to take an avalanche class. Look at our Education Page for all the classes being offered in sw Montana. They are working hard to break down Backcountry Barriers and made this awesome 6 min video about it.
