Travel and Terrain Advice

Approach lee and cross-loaded slopes with caution.

Avoid shallow, rocky areas where the snowpack transitions from thick to thin.

If you are increasing your exposure to avalanche terrain, do it gradually as you gather information.

Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
