Lo esencial

Triggering an avalanche large enough to carry and bury you is possible today. You'll see tracks most everywhere, but don't be fooled into thinking that those tracks mean a slope is safe from avalanches. Assume every slope is suspect and stay off steep slopes, especially those above terrain traps. 

A rider triggered and was partially buried by a small avalanche yesterday. Recent avalanches are the clearest evidence of an avalanche problem.

    Weak layers buried two feet beneath the surface can fail under the weight of a rider. In some areas where wind has deposited snow, these layers could be up to four feet deep. Recent avalanches, like the one triggered yesterday, are one of nature's most obvious warning signs. Reel in your desire to ride on steep slopes. You won't see a lot of avalanches or obvious signs in this zone unless you dig and look for weak layers. So far, avalanche activity on buried persistent grains have been on steep slopes. Keep to terrain below 30 degrees to significantly reduce your risk of being caught in an avalanche today.  

     

     

    A rider triggered this avalanche yesterday, December 31, 2025, somewhere in Togwotee Pass. This is the worst kind of terrain trap where even a very small slide can bury a person. Fortunately, this one had a lucky outcome.

  • Wind Slabs

    Look for signs of wind-loading such as drifts, cornices, scalloped and textured surfaces and areas that have been scoured to the ground. You'll find stubborn, and in most cases hard, wind slabs nearby. These have grown increasingly difficult to trigger but the weight of these slabs will make it more likely to trigger a persistent slab as mentioned above.

Avalanche Discussion

 

If you see anything avalanche related such as recent avalanches, cracking, or collapsing, please consider submitting an observation. Thanks to those who have submitted recently.
