At the higher elevations weak faceted snow persist near the base of the snowpack. Slab avalanches up to four feet in depth could be triggered on this weak layer in steep bowls, gullies and basins. Larger triggers such as high making snowmobiles or multiple sleds on the same slope are most likely to trigger one of these slab avalanches.
