In steep terrain at the mid and upper elevations skiers and riders could trigger slab avalanches on buried persistent weak layers. These slab avalanches could be one to three feet deep. At the lower elevations recent new snow lies upon well developed faceted snow. In these areas small pockets of surface slab up to 18 inches in deep could be human triggered on isolated terrain features.
