Some starting zones on north and northeast slopes still have a buried weak layer near the base of the snowpack. Recent observations indicate that the presence of this weak layer, found deep below the snowpack at ground level, is diminishing. However, the distribution of this problem may vary significantly, even in adjacent locations. While triggering a slide of this type will be unlikely, the consequences will be severe. The only way to determine the presence of this problem is to examine the snowpack, and in many loaded areas this could create a dangerous situation.
