Snowpack Summary
Wind affect in alpine areas can be seen. In some areas it is more extensive than others with dense windslabs up to 20cm thick. These slabs are in crossloaded features and along ridgelines. At treeline the slabs are much less prominent. Be careful in steep unsupported features where a smaller windslab may be reactive to a skier. Thinner areas are starting to facet out and loose strength but overall the snowpack is handling the cooler temperatures well and remains mostly supportive. Steep north facing terrain is producing loose dry sluffing in the upper snowpack as it weakens. Â
Terrain and Travel
- Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
- Avoid slopes that sound hollow or drum-like.
