GNFAC Avalanche Forecast for Fri Jan 14, 2022

Snowpack and Avalanche Discussion

<p>It remains possible to trigger an avalanche in the mountains around West Yellowstone and Cooke City. It’s been 6 days since the end of the last storm and while each day without snowfall does help the snowpack settle and stabilize, we still don’t completely trust the snowpack (<a href="https://youtu.be/1z0BBwxFFQE"><strong><u>Lionhead video</u></strong></a>). Skiers in the southern Madison Range yesterday saw several natural avalanches on Red Mountain (<a href="https://www.mtavalanche.com/images/22/avalanches-red-mountain"><strong>…;). These slides (along with a large slide on Sage Peak - <a href="https://mtavalanche.com/node/25494"><strong><u>photo</u></strong></a&gt;) likely broke last weekend, but provide examples of the sort of large avalanches that could still be triggered today. Digging to test the snowpack is your best bet to identify slopes where the weak layers at the ground remain unstable. The avalanche danger is MODERATE.</p>

<p>Avalanches are unlikely in the mountains around Big Sky and Bozeman. On Buck Ridge yesterday, I found the lower snowpack has been gaining strength and stabilizing (<a href="https://www.youtube.com/watch?v=nOQF5jw9ojY"><strong><u>video</u></stro…;). In general, the snowpack is now mostly stable. This does not mean it is impossible to trigger a slide. Yesterday, skiers in the northern Bridger Range saw a natural avalanche that likely failed several days ago (<a href="https://www.mtavalanche.com/images/22/natural-avalanche-near-fairy-lake…;) and got propagation under a wind slab in their Extended Column Tests. These signs of instability led them to choose to ski a mellower line than they had initially intended. This is the right mindset for today - be on the hunt for areas of isolated instability and look for reasons to back off your objectives. The avalanche danger is LOW near Big Sky and Bozeman.</p>
