Snowpack and Avalanche Discussion
<p><span><span><span><span><span><span>In popular areas, few slopes have been untouched by tracks and it’s been about a week since significant snowfall. </span></span></span></span></span></span></p>
<p><span><span><span><strong><span><span>Persistent slab avalanches</span></span></strong></span></span></span><span><span><span><span><span><span> remain the primary problem, but the odds of triggering one on most slopes is low; however, there are likely a few slopes lurking out there where you could trigger one of these slides 2-3 feet deep. Be most suspicious of slopes at mid elevations, in the trees.

This weak layer seems more pronounced in the southern Madison and Gallatin ranges and the Lionhead area.</span></span></span></span></span></span></p>
<p><span><span><span><span><span><span>At this point, this avalanche problem is isolated, and most slopes have generally safe avalanche conditions making the avalanche danger LOW. This doesn’t mean no danger. Isolated slopes can still produce avalanches, and I’d avoid steep terrain that runs into a terrain trap like trees, rocks, or a gully.</span></span></span></span></span></span></p>
<p><span><span><span><span><span><span>Shallow wind slabs - Increased winds from the west (especially in Hyalite Canyon) at upper elevations have formed wind slabs maybe 6-8 inches deep just under ridgelines. The threat of this problem will be determined by the terrain you choose today. These wind slabs will be most dangerous in extreme terrain where simply falling downhill can have severe consequences. With no new snow yesterday near Island Park, this problem is almost non-existent. </span></span></span></span></span></span></p>
<p><span><span><span><span><span><span>Today, avalanches are unlikely on the vast majority of terrain and the avalanche danger is LOW. Watch out for and avoid pockets harboring shallow wind slabs especially in more extreme terrain.</span></span></span></span></span></span></p>
