Bottom Line: The mountains throughout our advisory area have a layered snowpack, and avalanches can be triggered on steep slopes. Strong winds drifted last night’s snow into slabs which will continue to grow with strong west-southwest wind today and tomorrow. Identify and avoid fresh drifts on steep slopes. Expect to find these drifts along ridgelines. Look for signs such as round pillows of snow and feel for relatively hard or hollow slabs. Stay diligent with snowpack stability assessment and safe travel protocols through the weekend.

  • 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.
