The Colca Canyon: Peru's Natural Wonder
The Colca Canyon, twice as deep as the Grand Canyon and rivaled only by nearby Cotahuasi for the title of deepest in Peru, takes its name from the ancient qullqa storehouses of the Collagua and Cabana peoples, whose stone-walled agricultural terraces still feed the valley today and whose thermal-riding Andean condors have made this one of the best places on Earth to watch the world's largest flying bird.
