Small wind slabs may be found in lee terrain features from recent snow and strong southwest wind. Assess for slab properties before committing to steep terrain.

A few small (size 1.5) avalanches were triggered by riders and naturally in lee terrain features on Tuesday.
Please consider posting your observations to the Mountain Information Network to supplement our data stream and help fellow recreationists.
Around 10 cm of snow fell on Tuesday with associated strong southwest wind. New wind slabs may have formed in lee terrain features up high. The snow sits on 10 to 20 cm of consolidated snow over a hard melt-freeze. At lower elevations below treeline, the snowpack is moist and consolidated. Remember that cornices are large and looming at this time of year.
The remainder of the snowpack is strong, consisting of hard snow and various melt-freeze crusts.
