Highlights

Avalanches are unlikely, and most slopes are safe. Watch for small, isolated wind drifts in upper elevation and alpine terrain. In the White Cloud Mountains, triggering a large avalanche on weak snow near the ground remains a possibility on very steep, rocky, wind-affected slopes.

    The weak layers of snow near the ground in this zone haven't gone away, but a lack of recent snowfall has allowed them to go into a state of "dormancy". The snowpack structure hasn't changed significantly but triggering an avalanche on these layers of weak snow is unlikely. The White Cloud Mountains are where this problem remains at its worst, thanks to a larger amount of residual snow from September and October (video at right). Despite the lack of recent loading, trusting this sort of snowpack requires a true leap of faith. If I were going to go out looking for this problem today, I'd head to a very steep, open slope peppered with rocks that create thin spots in the snowpack and allow for easier access to the weak snow underneath.

    ADDITIONAL DISCUSSIONOn Saturday, 1-2" of new snow fell in this zone accompanied by moderate to strong winds blowing out of the SW-NW. Several observers in the Smoky and Boulder Mountains reported finding small, thin, isolated wind slabs that were sensitive to their weight. None of these slabs were large enough to bury a person, but they could knock you off your feet and send you tumbling down the slope. Since you are most likely to come across one of these slabs in steep, rocky, upper elevation terrain such a fall could have high consequences.

Avalanche Discussion

The potential for avalanches only truly goes to zero once the entire snowpack has melted. In light of that, continue to exercise caution when traveling in the backcountry. What does normal caution look like?

  • Make a solid plan before a day in the backcountry. A plan helps you anticipate hazards (of which avalanches are only one), identify options for the day, and ensure everyone is prepared for an emergency.
  • Perform a trailhead gear check. A proper beacon check ensures everyone's transceiver can send and receive a signal. Maybe you could use a brush-up on your beacon skills? Don't forget about the Baker Creek beacon park. Is everyone's radio working and on the right channel? Airbags armed and in working order?
  • Maintain situational awareness. Don't let your guard down even when the snowpack is generally stable. If you see a wind-loaded slope or another indicator of potential instability, don't assume it's safe just because the danger is Low. Identify and avoid other hazards such as large cornices. 
  • Communicate with your partners. As you travel through the mountains talk with your partners. Are you seeing what you were expecting to see when you made your plan in the morning or are conditions different than you thought that they would be? Do you need to adjust your plan accordingly?
  • Continue to use safe travel practices. It's easy to get sloppy with your travel practices during periods of stability. Continue to minimize your group's exposure to potential avalanche hazards, ideally traveling one at a time through steep terrain.
