Snowpack and Avalanche Discussion
<p>Strong cross-slope winds last week, and strong downslope winds prior to yesterday, drifted snow into slabs in unusual locations in the Bridger Range. Wind slabs one to two feet deep are located below ridgelines and across mid-elevation terrain. Carefully assess terrain for the presence of hard, thick drifts of snow, and avoid these features today. Less wind and limited snow transport yesterday allowed these slabs to gain strength, and they will be difficult to trigger today, but remain possible. Today, avalanche danger is <strong>MODERATE</strong> on wind loaded slopes and <strong>LOW </strong>on all other slopes.</p>
<p><a>A generally stable snowpack exists, and avalanches are unlikely without recent loading from snow and wind. I found these stable conditions in Beehive on Friday (</a><a href="https://www.youtube.com/watch?v=Yyk_tDXoH0w"><strong>video</strong></a&…;), and Doug and Eric had similar findings in Hyalite on Thursday (<a href="https://www.youtube.com/watch?v=RqIx4CG5zrM"><strong>video</strong></a&…;). Watch for isolated wind slabs, and assess terrain for the consequences of being caught in even a small slide.</p>
<p>Small wet loose avalanches were observed during the heat of the day on Friday (<a href="https://www.mtavalanche.com/images/17/small-wet-loose-slides-beehive"><…;, <a href="https://www.mtavalanche.com/images/17/wet-loose-cooke-city"><strong>pho…;), and are possible today. Sunny slopes will have a firm crust on the surface this morning, which will inhibit wet avalanche activity. If this crust softens, be cautious of small wet loose slides on sunny slopes this afternoon.</p>
<p>Conditions are generally stable, but it is important to continue safe travel habits. Expose no more than one person at a time to avalanche terrain. Practice clear communication and identifying safe zones. Take time to practice with your rescue gear.</p>
<p>Today, a generally stable snowpack without recent snow or wind-loading makes avalanche danger <strong>LOW</strong>.</p>
