Points saillants

There is a persistent weak layer in the snow pack.

Seek out smaller terrain with no overhead hazard to enjoy the good riding conditions at higher elevations.

Problèmes avalancheux

  • Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1.5–3

    At 60 to 100 cm deep, it can be most likely triggered on steep roll-overs in wind-sheltered terrain around treeline.

Confidence

Moderate

  • Uncertainty is due to the fact that persistent slabs are particularly difficult to forecast.

Avalanche Summary

Observations have been limited but reports of large (size 2) natural avalanches that happened during the weekends storm have been reported.

Small (size 1) human triggered avalanches have been reported in the region as well.

If you are getting out in the backcountry, consider sharing your observations on the Mountain Information Network (MIN)!

Snowpack Summary

25 cm of recent snow has fallen over a crust that is present up to 1400 m.

In sheltered areas, a layer of weak, feathery surface hoar crystals is buried about 75 cm deep.

At 1100 m and below a prominent crust is just below a skiff of fresh snow and makes for challenging travel.

The snowpack is around 150 cm deep at treeline, tapering quickly with elevation.

Terrain and Travel Advice

  • Surface hoar distribution is highly variable. Avoid generalizing your observations.
  • Be aware of the potential for large avalanches due to buried surface hoar.
