Lo esencial

If you're getting out there in the cold, keep in mind that being involved in an avalanche in extreme cold temperatures makes for higher consequences.

North winds will deposit any loose snow into new wind slabs through reverse-loading.

Look for higher quality riding in sheltered terrain features well below ridge line.

    A good amount of north wind is forecast for the coming days, especially at higher elevations. Pay attention to the snow beneath you and watch for signs of instability including shooting cracks and stiffer, drum-like snow. This will most likely be found directly below ridge lines and on the side walls of steep gullies. Find better quality riding in sheltered terrain features down low.

Avalanche Summary

Our field team reported one size 2 natural wind slab avalanche on a southeast facing alpine feature at 1900m 48-72hrs old.

Thank you for the MIN reports. They are extremely helpful to us! If you head into the backcountry please submit a MIN report!

Snowpack Summary

In general, the snowpack is highly wind affected resulting in a wide variation in snowpack depths. Depths at treeline range from 50 to 125cm. Riding quality is best in sheltered terrain.

The snowpack is somewhat shallow but for the most part settled and well consolidated with no layers of concern being reported.

Terrain and Travel Advice

  • Watch for areas of hard wind slab on alpine features.
  • Use ridges or ribs to avoid areas of wind loaded snow.
