    The bottom of the snow pack is inherently weak with well developed Facets and Depth Hoar. Avalanches initiating in the upper snowpack are likely to step down to this layer and gain significant mass.

Terrain and Travel Advice

  • Make conservative terrain choices and avoid overhead hazard.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
