Moss only grows on the north side of trees. Do survival texts still tell us to look for moss if we want to know which way is north?

It used to be standard rhetoric for Boy Scouts (and presumably any Girl Guide who chose to wander into the woods on her own, unaccompanied by an aforementioned Boy Scout).

Another good story debunked by Mother Nature. This grove of aspens is facing south; each tree sports a dark green collar of moss around its base.

Northside-only moss is on par with leaving a trail of breadcrumbs — best for fairy tales. A compass or GPS makes for a safer travelling companion. 🙂
