What's the 30 - 30 rule?
The "30 - 30 rule" stands for 30 seconds, then 30 minutes.
30 seconds -- Let's say you're outside and you see lightning in some direction, even if there's blue sky above you. Start counting to 30 by saying, "one one-thousand, two one-thousand, three one-thousand," and so on. If you hear thunder before you get to "thirty one-thousand," then that means the storm is too close to you and you should go inside a building. The building could be the Visitor Center, or Lodge...or even one of the bathrooms near a viewpoint. A bus shelter with open sides will protect you from rain, but not from lightning!
If you can't go inside, you should get into a metal car, Park shuttle or school bus. If the lightning hits the vehicle, the metal will conduct the lightning around you, not into you.
Do not stand under a tree! As the picture shows, the tree could act like a lightning rod, bringing the electricity down to you! Many trees in Bryce Canyon National Park have been hit by lightning. In some cases, the tree has survived, but it has a scar. Look for these tree lightning scars as you hike along the trails.
