Points saillants

The snowpack is weak and faceted. Backcountry travelers have the potential to trigger persistent slabs on a variety of aspects and elevations. Isolated pockets of newly formed soft slab could also be triggered in steep, wind-loaded terrain to depths of six inches. Careful snowpack and terrain evaluation followed by thoughtful decision making will be necessary for safe travel in avalanche terrain today.

    Persistent weak layers exist in the snowpack. These layers formed during cold, dry periods and were buried on December 8th and January 5th. The weight of a single person could cause failure of these weak layers creating a slab avalanche with depths of one to four feet. Larger loads, such as groups of people or snowmachines, are more likely to trigger one of these events.
