Lo esencial

The cooler weather has helped to stabilize the snowpack, however we continue to be wary of deeply buried weak layers.

Problemas de aludes

  • Wind Slabs

    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    1–1.5

    Wind slabs are becoming stubborn but may be triggered by riders in steep lee terrain features.

  • Deep Persistent Slabs

    Multiple weak layers in the snowpack remain a concern. Most specifically facets on crust near the base of the snowpack. Be especially cautious in areas where the recently formed crusts near the surface are not supportive.

Moderate

Avalanche Summary

No new natural avalanche activity. Explosives control work in the north of the region produced a size 1.5 soft slab 10 cm deep in steep alpine/treeline terrain.

Snowpack Summary

Roughly 10 cm of accumulated new snow over a crust that tapers in thickness at higher elevations.

Below the fresh snow and mentioned crust, there is around 50 cm of moist snow that is drying out and strengthening with cool temperatures. Multiple crust and facet layers exist beneath and the base contains weak faceted grains and depth hoar, which will continue to be monitored for reactivity.

Terrain and Travel Advice

  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
