Points saillants

Don't let the recent snow draw you into big terrain, as triggering large avalanches remains possible in steep, rocky areas.

    1.5–2.5

    A layer of weak facets near the ground may be triggerable by riders. Especially in shallow, rocky alpine terrain where it is not covered by a thick crust.

Moderate

Avalanche Summary

No recent avalanches have been reported.

If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

Recent snow continues to accumulate atop a shallow, generally weak and unconsolidated snowpack.

The mid and lower snowpack contains a variety of layers including unconsolidated facets, crusts, and old wind-affected snow.

Weak basal facets characterize the lower snowpack, especially in alpine terrain.

Snowpack depths at treeline average 50 to 130 cm.

Weather Summary

Terrain and Travel Advice

  • Use caution on large alpine slopes, especially around thin areas that may propagate to deeper instabilities.
  • Avoid areas where the snow feels stiff and/or slabby.
  • Be especially cautious near rock outcroppings, on steep convexities and anywhere the snowpack feels thinner than average.
