Points saillants

A very shallow snowpack exists with numerous hazards present either at or just below the snow surface.

Remember, if the snow is deep enough to ride, it is deep enough to trigger an avalanche.

    Deep pockets of wind-loaded snow may sit atop a weak, facetted lower snowpack.

Avalanche Summary

No recent avalanches have been reported. Information from the field is sparse this time of year. Consider submitting a MIN report if you are recreating in the mountains.

Snowpack Summary

The snowpack is generally very shallow and contains many potential hazards just beneath the snow surface. At treeline, the height of snow ranges from approximately 50 to 100 cm. As you descend to lower elevations, snow depths decrease significantly. In the alpine, the snowpack remains relatively shallow and shows signs of heavy wind scouring.

In areas with deeper snow accumulations, wind-loaded snow may sit atop a weak basal snowpack.

The bottom of the snowpack consists of a combination of weak facetted crystals and multiple melt-freeze crusts.

Terrain and Travel Advice

  • Expect shallow snow cover that barely covers ground roughness.
  • Winter conditions may exist in gullies, alpine bowls, and around ridgelines.
  • If it's deep enough to ride, it's deep enough to slide (avalanche).
