Salt River and Wyoming Ranges

You may encounter unstable snow in isolated terrain features and where snow has remained on the ground since October. Cracking and collapsing are clear indicators of instability. Avoid terrain where the wind has built stiffer slabs, and reduce your risk further by continuing to move one at a time in avalanche terrain. 

Backcountry users in the Tetons and Togwotee have already reported natural avalanches in steep, alpine terrain or significant signals like collapsing that indicate avalanches could occur. Regardless of what you’re doing in the mountains, whether it’s going hunting, snowshoeing, getting some early-season turns, or breaking out the snowmobile, be prepared for avalanches. The bottom line is simple: If there’s enough snow to ride, there’s enough snow to slide. 

Because information is limited this time of year, we have not issued ratings for the Greys River yet. We will start issuing ratings as soon as we have gathered more snowpack data. In the meantime, be suspicious of steep slopes any time you find continuous snow that hides vegetation and rocks. As snow cover increases, so could the likelihood and size of avalanches. You’re most likely to encounter unstable snow:

• on steep wind-loaded slopes
• in higher elevation terrain where the snowpack may be much deeper

When in doubt, stick to lower-angled or less consequential terrain.
