While traveling, pay attention to newly formed wind slabs that may be reactive to rider traffic in some areas.
New wind slabs formed on Monday and Tuesday below ridgelines and convexities. They may still be reactive to skier traffic. Their estimated thickness ranges between 10 and 30 cm.
Several avalanches that occurred on Sunday and Monday were reported on the Mountain Information Network (MIN). These skier-triggered avalanches took place in alpine terrain and at treeline on north through southeast aspects.
If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).
In some areas, up to 40 cm of new snow fell during the last storm, Sunday. This snow rests on a variety of surfaces: wind-affected snow, powder snow, or sun crust.
A widespread melt-freeze crust about 2 cm thick is present at depths of 40 to 70 cm. A weak layer of faceted grains has developed on this crust on north to east aspects and is reactive in tests at treeline and in alpine terrain.
At mid-elevation, the average snowpack depth is around 140 cm.
