Weak, faceted snow exists near the base of the snowpack. Backcountry travelers could trigger deep persistent slab avalanches on these problem layers. These dangerous slides are most likely to be triggered by a snowmobiler or a cornice drop during the warmest portion of the day and could occur on slopes that have been previously tracked. A failure there can propagate into deeper snow resulting in a slide that could be 3 to 5 feet deep and cause serious injury or death.
