Lo esencial

Most of the new snow fell to the north and east of the region. Investigate how the unconsolidated snowpack reacts to this new load before you commit to your ski line or ice climb.

Problemas de aludes

  • Loose Dry

    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Very Likely
    Tamaño
    1–2

    A handful of loose dry avalanches have occurred recently with one scrubbing to ground. They are currently limited to specific terrain such as very steep alpine rocky terrain yet enough of a concern if a person is standing below it or gets swept away. This currently is our most active problem.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2.5

    You must keep this basal layer on your radar as triggering is possible in isolated features, such as steep rocky terrain where you find yourself standing on the surface and not wallowing in facets, that's the problem slab.

Moderate

Avalanche Summary

Loose dry avalanches up to size 2 in very steep rocky alpine terrain were noted over the past few days. Some are scrubbing to ground. They do not appear to be initiating any deeper weakness' in the snowpack.

Snowpack Summary

About 10cm of snow fell in the north and east section of the park with about 3cm around the Parker Ridge area. Tree line snowpack depth is an average of 45-75cm. The snowpack is weak and largely unsupportive after this cold weather.
