Nazca Lines, Peru
The Nazca Lines are a series of ancient geoglyphs located in the Ica Region in southern Peru. Estimated to be created by the Nazca culture between 400 and 650 C.E., the Nazca Lines were made by removing reddish iron-oxide pebbles that cover the surface of the desert. When the gravel is removed, the lines contrast with the light color underneath. In this 2000 Terra image, the straight Nazca Lines differ sharply from the natural, wavy lines formed from water flow in the area. Overall, there are hundreds of individual figures, which range in complexity from simple lines to stylized hummingbirds, spiders, monkeys, fish, sharks, orcas, llamas, and lizards. The Nazca Lines were designated a UNESCO World Heritage Site in 1994.
