Abpve 8000 feet, large slab avalanches could be triggered on buried persistent weak snow layers with depths of one to three feet. At the lower elevations recently fallen snow lies upon a snowpack that was mostly faceted last week. Slabs to a foot in depth could be triggered in steep isolated terrain features.
