Lo esencial

Look for sheltered terrain for the best skiing and avoid thin to thick areas in the alpine.

    • Alta montaña
    • Límite del bosque

    Wind slabs will need a few days to heal.

    Use caution around thin to thick areas where buried weak layers could be triggered.

Snowpack Summary

45cm of new snow further buries the mid-December persistent layers, (surface hoar and facet combo) down 40-70cm. The mid-pack is supportive where snow is deeper than 60cm. The bottom of the snowpack consists of facets and depth hoar.

Avalanche Summary

During the storm on Jan 3. serval large natural avalanches were observed in the alpine on all aspects. Avalanche control had varied results from no results to several size 3 wind slabs stepping down to deep weakness on all aspects in the alpine.
