Primary Problem: Wind-Drifted Snow
Bottom Line: New snow and wind-loading are the main avalanche concerns today. They are creating instability in the upper 1+ foot of the snowpack, and the weaker, faceted snow near the ground is more difficult to trigger, but not impossible. Rocks sticking out in starting zones indicate shallow areas where a person could trigger a large and deadly slide. Today is a day of active loading and the snowpack will be most sensitive to triggering, both naturally and by people. Dangerous avalanche conditions are back. Be careful getting near avalanche terrain and be especially mindful of terrain traps.
