Human-triggered wind slabs are possible.
Monitor for signs of instability, and avoid committing to steep slopes if the snow feels dense.
Wind slabs formed on most aspects at treeline and above continue to remain active. Human-triggered wind slabs remain possible and are more likely in open terrain features.
Several human triggered size 1 to 1.5 wind slabs were reported on Saturday. These avalanches were mostly in open terrain features and steep terrain near ridge lines.
Up to 25 cm of recent snow has been redistributed by variable winds forming isolated wind slabs on most aspects. Below this a wind affected upper snowpack exists.
Roughly 110 to 150 cm of settling snow sits on the mid-December crust.
This forms the basal snowpack to about 2200 m. Above this elevation, a deeper snowpack with a crust and associated facets, formed in mid-November, can be found just off the ground.
