Multiple persistent weak layers exist in the snowpack. These weak layers are comprised of faceted snow and are potential bed surfaces for avalanche activity. Soft slabs up to 18 inches in depth could be human triggered on recently buried surface hoar. Older hard slabs with depths to five feet could be human triggered with severe consequences on deeper buried layers of faceted snow.
