Snowpack Summary
Wind slabs are found on the surface in wind-prone alpine terrain, and below the surface in lee and cross-loaded terrain features. A few slab avalanches (both human and naturally triggered) in steeper terrain have been noted in recent days. The basal layers of the snowpack are typical of the eastern Rockies for this time of year, and consist almost entirely of facets. Unfortunately this condition is not going anywhere fast, and may be with us for the season.
