Points saillants

Triggering a large avalanche 2-3 feet deep is possible today on very steep slopes. The danger is greatest in shady terrain above 8000 feet where weak snow remains preserved and buried.  Small avalanches on steep, upper elevation terrain exposed to the wind are also possible. Evaluate steep slopes carefully and use caution around wind-affected terrain. Identify terrain traps where even small avalanches could bury you.

    Weak snow formed in January is buried 2 to 3 feet deep below a hard slab. It is becoming less likely that you will impact these weak layers, but it is still possible on very steep northerly slopes. Pockets of buried surface hoar near the top of the drought facet layer are most concerning. The distribution of this buried surface hoar is spotty, but mostly between 8,000 and 9,500 feet on very steep (35°+), shady, and sheltered terrain. Identify terrain with these characteristics and evaluate carefully. Keep an eye out for very steep terrain traps around creek gullies that often harbor surface hoar.

    This avalanche was triggered yesterday on a sheltered slope which had a skin and ski tracks on it.  

Avalanche Discussion

The Salt River and Wyoming Ranges have received less snow than other zones to the north. It is unlikely that you will encounter any reactive wind slabs, but with strong winds over the last 48 hours, keep them on your radar. There could be pockets of shallow wind slabs at upper elevations. Don't let this catch you off guard, and if you are travelling along ridgelines or around rocky outcrops, keep an eye out for drifts and shooting cracks.

The freezing level was around 8000 feet overnight. We have not had much new snow below this elevation to cause major concern for wet-snow avalanche problems. Crusts at middle elevations will break down as temperatures climb today. If you travel in steep terrain below 8,500 feet and find wet surface conditions or see rollerballs coming from your skis, move to lower-angle terrain. 

Thanks for submitting your observations. Snap a few photos while you’re out and send them in; it’s a huge help!
