22-23

<p><span><span><span><span><span><span>There is weak snow buried 2-3 ft deep that could avalanche under the weight of a skier or rider today (</span></span></span></span></span></span><a href="https://www.youtube.com/watch?v=O2iI_MqPIqE"><span><span><span><strong>… Fork video</span></span></u></span></strong></span></span></span></a><span><span><span><span><span><span>). Several natural slides broke on these layers during the loading event early in the week and on Tuesday a rider triggered a large slide near Daisy Pass (</span></span></span></span></span></span><a href="https://www.youtube.com/watch?v=N8CtHy3efxs"><span><span><span><strong>… Pass video</span></span></u></span></strong></span></span></span></a><span><span><span><span><span><span>, </span></span></span></span></span></span><a href="https://www.mtavalanche.com/node/27117"><span><span><span><strong><span… Fork details</span></span></u></span></strong></span></span></span></a><span><span><span><strong><span><span>, </span></span></strong></span></span></span><a href="https://www.mtavalanche.com/node/27113"><span><span><span><strong><span… photo and details</span></span></u></span></strong></span></span></span></a><span><span><span><span><span><span>). The snowpack has now had a few days to accommodate the stress of new and wind drifted snow. Natural avalanches have become unlikely, but human triggered slides remain possible. Dig to search for and test these weak layers in the middle of the snowpack before riding steep slopes. Be doubly skeptical of the weak layers if they are sitting beneath hard slabs of wind drifted snow. Also watch for thin fresh drifts forming today as new snow accumulates.&nbsp;</span></span></span></span></span></span></p>

<p><span><span><span><span><span><span>The avalanche danger is MODERATE.</span></span></span></span></span></span></p>

<p><span><span><span><span><span><span>In the mountains around Bozeman and Big Sky, the primary avalanche concern is slides breaking in drifts of wind-blown snow.&nbsp;</span></span></span></span></span></span></p>

<p><span><span><span><span><span><span>Yesterday, the Yellowstone Club Ski Patrol saw two small avalanches on wind drifted slopes on Cedar Mountain that broke naturally sometime in the last few days (</span></span></span></span></span></span><a href="https://www.mtavalanche.com/node/27134"><span><span><span><strong><span… and photos</span></span></u></span></strong></span></span></span></a><span><span><span><span><span><span>). On Monday, two skiers were carried 600 ft by an avalanche that initially broke only 6 inches deep as they ascended a couloir on Ross Peak (</span></span></span></span></span></span><a href="https://www.mtavalanche.com/node/27091"><span><span><span><strong><span… and photos</span></span></u></span></strong></span></span></span></a><span><span><span><span><span><span>). They ended up partially buried with snow packed into the mouth of one skier. This is a good reminder of the power of even a shallow slab.&nbsp;</span></span></span></span></span></span></p>

<p><span><span><span><span><span><span>Watch out for and avoid these wind drifts, or carefully check to see how they’ve bonded before riding steep slopes. We also can’t yet rule out the possibility that there are weak layers on some slopes. Dig and look for weak layers hiding 1-2 ft deep. If you find them, retreat to lower angled terrain and </span></span></span></span></span></span><a href="https://www.mtavalanche.com/node/add/snow_obs"><span><span><span><span>… in an observation</span></span></u></span></span></span></span></span></a><span><span><span><span><span><span> to let us know where you found them.&nbsp;</span></span></span></span></span></span></p>

<p><span><span><span><span><span><span>Human-triggered avalanches are possible and the danger is rated MODERATE today</span></span></span></span></span></span></p>

<p><span><span><span><span><span><span>4-8” of new snow are possible in the Island Park area during the day today. There is weak snow buried 2-3 ft deep in the Lionhead area (and it likely exists in the Island Park area as well) that could avalanche under the weight of a skier or rider today. Dig to search for and test these weak layers in the middle of the snowpack before riding steep slopes. Also watch for fresh drifts forming today as new snow accumulates, if it’s drifted more than a few inches deep you could trigger a dangerous slide.</span></span></span></span></span></span></p>
