Rules of 3 for Caving
By Val Hildreth-Werker

I've used this with lots of scouts:

  • Always cave in groups of at least three people.
  • Always tell three people where you're going and when you'll be out of the cave.
  • Always have three light sources
  • Use three points of contact on climbs
  • The international emergency signal is what? Three of just about anything. Three toots on a whistle. Three honks on a vehicle horn. Three giant x's made of rocks or snow.
