In sintesi

The snowpack in the park changes dramatically as you leave the area immediately around Cameron Lake. Take the time to evaluate conditions locally if you move east of the Divide.

Problemi valanghivi

    Windslabs could respond to human traffic in steep unsupported features, or thin areas where they sit on basal facets.

    We are reluctant to put much trust in deeper weak layers. The December 9 Crust/facet combo can be found down 30-80cm, and may respond to large triggers such as smaller avalanches or cornice failures. Basal facets are also on our radar in thin areas.

Weather Forecast

Wednesday through Friday will bring relatively similar conditions: Mainly cloudy with isolated flurries bringing up to 10cm of snow spread over the three days, moderate to strong SW ridgetop winds, and alpine highs of -7.

Snowpack Summary

Snow depth is highly variable, and alpine and front range areas are very wind affected. The Cameron Lake area has seen much less wind treeline and below. The December 9 crust facet combo is down 30-80cm, still giving hard sudden results in test profiles. A sandwich of crusts and facets form the base of the snowpack.

Avalanche Summary

No recent avalanches observed

Confidence

The weather pattern is stable
