<p>Triggering avalanches is likely today on steep slopes in the Bridger Range, Madison Range, southern Gallatin Range and Lionhead area. Numerous natural and human triggered avalanches have been reported over the last few days (see the <a href="https://www.mtavalanche.com/avalanche-activity"><strong><u>avalanche log</u></strong></a> a full list). Some highlights include: natural avalanches on <a href="https://www.mtavalanche.com/node/23556"><u>Saddle Peak</u></a> and <a href="https://www.mtavalanche.com/node/23552"><u>Fan Mountain</u></a>, many natural and snowmobile triggered <a href="https://www.mtavalanche.com/node/23628"><u>slides in the Taylor Fork</u></a>, a <a href="https://www.mtavalanche.com/node/23601"><u>remotely triggered avalanche</u></a> in the northern Madison range, and a skier triggered slide in <a href="https://www.mtavalanche.com/node/23598"><u>Bradley’s Meadow</u></a> near Bridge Bowl. New snow over the last four days clearly pushed the snowpack past its breaking point. Unfortunately, these weak layers do not heal quickly. They are called <strong><em>persistent</em></strong> weak layers for a reason. While the northern areas got a bit more snow yesterday, the weak snow at the ground remains primed to avalanche across the region. Additionally, with the most new snow and strongest winds, newly formed wind drifts will be easily triggered in the Bridger Range.&nbsp;</p>

<p>Avoid travelling on or underneath slopes steeper than 30 degrees today. The avalanche danger is rated CONSIDERABLE.&nbsp;</p>

<p>The northern Gallatin Range has the same unstable combination with just a little bit less recent snowfall to stress the weak layers at the ground. Don’t let your guard down. Stay alert for signs of instability and dig to test the weak layers at the ground before committing to steep terrain. Human triggered avalanches are possible and the avalanche danger is MODERATE.</p>

<p>Over the last three days, skiers triggered an avalanche on Henderson Mountain, got collapses/whumpfs while skinning, and saw several avalanches north of town (<a href="https://www.mtavalanche.com/node/23573"><strong><u>details</u></strong>…;, <a href="https://www.mtavalanche.com/node/23612"><strong><u>photos and details</u></strong></a>). Yesterday, skiers south of town got very unstable test results on a weak layer buried 2 ft deep. While weak layers are not as widespread as in other regions, they are out there and need to be checked for before riding steep slopes. Digging in the snow is your best defense against these sporadically distributed weaknesses. Today, the avalanche danger is rated MODERATE.</p>
