Lo esencial

Triggering avalanches 1-3 deep is possible in steep terrain in the upper elevations today. Consequences of triggering avalanches at this depth are high and warrant conservative terrain choices. Isolated pockets of recently formed wind slab up to 1 foot thick could also be triggered in steep terrain above 9,000 feet.

    Weak snow that formed in early December sits 1-3 feet below the surface and remains a lingering threat today. Triggering an avalanche at this depth carries severe consequences. While it is becoming more difficult to trigger these deeper layers, it cannot be ruled out. Thin spots in the slab are the most likely spots to impact these layers. Large triggers in the form of groups, snowmobiles and falling cornices will increase the odds of impacting these layers. Use safe travel practices in order to minimize your exposure to this problem. Travel one at a time across steep terrain, use islands of safety when stopped and communicate plans with your group members throughout the day.

    Fresh wind slabs up to a foot in depth have formed over the last 36 hours. These slabs will be most sensitive in the upper elevations, where winds have deposited snow on the leeward sides of ridges and slopes. Expect these slabs to be isolated to the highest elevations that have received the higher end of snow amounts and wind. Be on the lookout for shooting cracks and stiff, rounded or pillowed snow. When encountering these signs move to less steep terrain.

Avalanche Discussion

The snowpack on Togwotee is generally shallow and weak. The early season brought minimal amounts of snow and generally cold temperatures. This helped to form weak layers of snow close to the ground. Beginning in mid December, storms deposited snow and created slabs on top of this weak snow. Average slab depths now range between 1-3 feet. Obvious signs such as recent avalanches, shooting cracks, or collapsing may not present themselves prior to triggering. An avalanche was triggered just over a week ago resulting in a fatality. This is a sobering reminder of the serious nature of triggering and involvement in avalanches at these depths. With the passage of time it becomes more difficult to trigger these deeper layers. Despite this improving trend, it is important to keep this problem on the radar. Patience is key when dealing with a persistent slab problem and today’s approach should be no different than yesterday.

If you see avalanche activity today, please consider submitting an observation HERE. Observations allow everyone to gain a better and more complete understanding of conditions. Thanks!
