  This layer continues to settle and is becoming less of a concern. Steep cross loaded or lee slopes are likely trigger zones. Alpine snowpack depth remains highly variable. At treeline and below, travel is good and the snowpack is supportive.

  These slabs are sitting over a weak basal facet layer. Most large avalanches that have been observed recently have been on this layer. It can be most easily triggered from shallow areas on the edge of fatter slopes.
