Lo esencial

Triggering large, destructive avalanches is unlikely, but not impossible. You can avoid steep, rocky terrain where the wind has drifted or stiffened the snow surface to reduce your chances of finding trouble. Small, loose snow avalanches are possible on very steep, rocky slopes facing the sun.

    Your odds of triggering a dense, 2-5 foot thick slab avalanche are low but not zero. You may still find this problem in isolated areas on slopes facing the northern half of the compass, where the wind frequently blows and the snowpack depth is variable. Avalanches are easier to trigger in thin spots at the edges of slabs. Here are some visual clues to identify suspect slopes:

    • Wind-pillows, and textured surfaces where the wind has moved snow  
    • Rocks sticking out of the snow and wind-scouring along mid-slope gullies

    Remotely triggering an avalanche from flat terrain near steep slopes remains a possibility. If you do trigger an avalanche, you probably won't observe obvious signs of instability like snowpack collapsing or cracking beforehand. 

    Additional Discussion: Loose snow avalanches are possible on very steep slopes facing the sun. These often initiate near exposed rocks. Most will be small, but some may grow large enough to bury you beneath large slopes and in funneled terrain. You can reduce your risk by limiting your time spent beneath sun-drenched slopes that look like this, especially during the heat of the afternoon.  

    (1/11/2025) We observed this recent wind slab avalanche above Dollarhide Summit in an obviously cross-loaded gully. We estimate that it failed on January 8/9 during peak winds. There may also be evidence of a refilled, deeper persistent slab avalanche along the ridgeline. Photo: Sawtooth Avalanche Center

Avalanche Discussion

Our odds of triggering a large avalanche are low, but professionals continue to cautiously choose slopes with uniform, planar entrances and short sections of lower-angle avalanche terrain (low 30-degree slopes).

Continue to practice safe travel protocols. Travel with a skilled partner and keep each other in sight. If you choose to enter avalanche terrain, do so one at a time and stack the odds in your favor by avoiding slopes that end in terrain traps like thick trees, cliffs, and creek bottoms.
