Lo esencial

Buried weak layers are an unusual feature of the snowpack in this region.

Choose conservative terrain and avoid steep or large open slopes.

Problemas de aludes

  • Wind Slabs

    Probabilidad
    Possible - Likely
    Tamaño
    1–2

    Watch for fresh wind slabs at higher elevations where dry snow can be found. Wind slabs likely sit over a crust, increasing reactivity.

  • Persistent Slabs

    While avalanche activity on this layer has decreased, persistent slab avalanches remain possible and are most likely to be triggered by large loads such as cornice falls.

Moderate

Avalanche Summary

No new avalanches were reported.

Avalanche activity on the November crust layer has decreased, persistent slabs remain possible and are most likely to be triggered by large loads.

Snowpack Summary

Roughly 10 cm of new snow redistributed by strong southwest wind may be found at at upper elevations.

A mid November melt–freeze crust with surface hoar and/or faceted grains lies 40–80 cm below the snow surface. Another crust and facet combination from late October can be found at the base of the snowpack.

Terrain and Travel Advice

  • Be aware of the potential for large avalanches due to buried weak layers.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
