At the mid and upper elevations cohesive slabs sit upon a buried weak layer of faceted snow that lies atop a hard crust. This problem layer and bed surface can produce human triggered avalanches two to four feet deep on a variety of aspects, but has been most active on north through east to southeast aspects. Avalanches are unlikely below an elevation of 7,500 feet.
