The Nazca Lines are a series of ancient designs etched into a plateau in the Nazca Desert of Peru. The etchings extend about 50 miles, with some individual drawings measuring more than 600 feet across. Some of the drawings are of animals, birds and human beings, while others are simple lines and geometric shapes.
