In sintesi

Triggering an avalanche on steep wind-affected slopes at upper elevations is possible today. Riders could also trigger a large avalanche that fails on weak snow buried near the ground.  The danger is highest in steep, rocky, and exposed terrain. Evaluate this terrain carefully, watch for cracking in recent snow, and steer clear of terrain traps.

    Wind slabs exist in exposed terrain at upper elevations. Expect to find this problem on multiple aspects due to shifting winds over the last several days combined with several inches of recent snow. These slabs could be up to 18 inches deep. Watch for pillows and stiff drifts below ridges and in cross-loaded terrain. Avoid steep terrain with signs of instability including cracking at your ski tips.

    The persistent slab problem exists at all elevations and on all aspects on Togwotee pass. Weak, sugary snow is buried 2-4 feet below hard slabs. Digging and probing will show you exactly where the problem is. Steep, rocky, and wind-affected slopes on west through north through east aspects should be evaluated carefully.  The underlying weak layers are more easily impacted on slopes with thin areas of snowpack.

    Keep an eye out for cornices above you. Cornices can break unexpectedly and act as very large triggers, impacting deep weak layers and causing large avalanches.

Avalanche Discussion

A return to winter temperatures today has decreased the avalanche danger. Wet avalanche activity is unlikely as colder temperatures, increasing clouds and a chance of snow dominate the short-term forecast. 

If you were at the hill climb championships at Snow King this weekend, you might be extra motivated to go out today in search of the combination that dreams are made of: high-octane pumping through a wide-open throttle charging up steep powdery slopes. I'll be wearing my Pit Vipers and might even start my playlist with some Eye of the Tiger. After all, training for next year's competition starts today. However, as you ride, continue to identify terrain that warrants concern including steep wind-affected slopes and thin areas of the snowpack on northerly aspects where your chances of triggering an avalanche are elevated. If you find yourself in avalanche terrain where concerning slopes are in play, consider the consequence of getting caught and carried. Watch out for terrain traps.
