They are even more famous, however, for an extraordinary but puzzling set of creations known as the Nazca Lines, which are geoglyphs and geometric line clearings in the Atacama desert, in the district of Nazca. On a large, rock-strewn plain, the Nazca made huge drawings by scraping away stones to reveal the lighter soil underneath. The drawings depict various plants and animals, including humans, a monkey, birds, and other creatures, as well as lines and geometric shapes. These drawings are so huge, however, that they can be seen only from the sky. Scientists believe that the Nazca made these drawings for their gods. The area of the Nazca lines is called the Pampa Colorada (red plain).
