A canyon was a geological formation, a deep and narrow valley between high cliffs.
History and specifics[edit | edit source]
In the year 2266 on the planet Neesan, James T. Kirk and Montgomery Scott ran from members of the Kovar people into a nearby canyon. Kirk then used his phaser to start a rockslide which blocked the canyon's entrance, cutting off their pursuers. (TOS comic: "The Cosmic Cavemen")
