Wet slide near Emigrant Peak
Debris field from likely a wet slide on a steeper slope in the back bowl near Emigrant peak. Slide was on an east-south/east facing slope. Not sure the date of slide.

<p><span><span><span><span><span><span>Today’s new snow creates additional avalanche hazard, especially where southwest-west winds drifted the snow into thicker slabs. These slabs will be easy for a person to trigger and potentially large enough to bury someone. Also, a person can trigger larger avalanches that break multiple feet deep and hundreds of feet wide on buried persistent weak layers. These potentially massive avalanches have become less likely over the last couple weeks, but the consequences remain severe, and today the likelihood has increased on wind-loaded slopes. </span></span></span></span></span></span></p>
<p><span><span><span><span><span><span>The most recent avalanche that broke on a deeper weak layer was last Tuesday near Mt. Blackmore, and resulted in a skier being caught and injured requiring a helicopter rescue from GCSAR (</span></span></span></span></span></span><a href="https://www.mtavalanche.com/node/31526"><span><span><span><strong><span… and photos</span></span></u></span></strong></span></span></span></a><span><span><span><span><span><span>). Yesterday near Cooke City skiers triggered a large collapse of the snowpack on a low angle slope (</span></span></span></span></span></span><a href="https://www.mtavalanche.com/node/31570"><span><span><span><strong><span…;). Additional reminders of this hazard include a huge remotely triggered slide in the Absarokas last week (</span></span></span></span></span></span><a href="https://www.mtavalanche.com/node/31460"><span><span><span><strong><span…;), a rider triggered slide in Taylor Fork (</span></span></span></span></span></span><a href="https://www.mtavalanche.com/node/31479"><span><span><span><strong><span… and photo</span></span></u></span></strong></span></span></span></a><span><span><span><span><span><span>), a big slide that broke naturally on the north face of Mt. Blackmore (</span></span></span></span></span></span><a href="https://www.mtavalanche.com/node/31432"><span><span><span><strong><span…;), and this </span></span></span></span></span></span><a href="https://youtu.be/K_t6Fi6wUC4?si=7YL80dNe5pSqJUsL"><span><span><span><st…; from early January showing the very poor foundation of the snowpack supporting all the snow that has since fallen. Assessing the stability of the deeply buried weak layers is difficult. To manage this problem, the best strategy is careful terrain selection and sticking to safe travel practices.</span></span></span></span></span></span></p>
<p><span><span><span><span><span><span>Be extra cautious of steep wind-loaded slopes today. Signs that slopes are wind-loaded include cornices hanging off the ridgeline above, a textured or rounded pillow-like snow surface, or cracks shooting across the surface from your feet or skis.</span></span></span></span></span></span></p>
<p><span><span><span><span><span><span>If you plan to ride steeper slopes, choose smaller and simpler slopes with clean runouts free of trees, cliffs, rocks or confined gullies, and without recent wind-loading. Only expose one person at a time to steep slopes, watch your partners from a safe spot while they’re on those slopes, and make sure everyone carries rescue gear (avalanche beacon, shovel, and probe). Today, on wind-loaded slopes human-triggered avalanches are likely and the avalanche danger is CONSIDERABLE, and on non-wind-loaded slopes the avalanche danger is MODERATE.</span></span></span></span></span></span></p>

From obs. 3/23/24: "Walked out the north gate of bridger to the playground. Just north of Texas meadows observed a slide that ran sometime earlier in the week on a E aspect. Seems to have been triggered naturally by a loose wet coming out of the steep rocky terrain above. Ran about 200 feet was about 50-60 feet wide and crown was roughly 2-3 feet deep. Snow around the slide and on similar aspects was wet in the top 40 cms or so."
