  1. Ski only north-facing slopes
  2. Avoid all avalanche terrain ✔
  3. Go in a big group

Why: At Extreme danger, natural and human-triggered avalanches are certain. The only safe plan is to stay out of avalanche terrain and run-out zones.

Huh, didn't know that: At High (level 4), avalanche.org says you don't have to be on a steep slope to be hit by a slide that starts above you.
