The document discusses the Nazca Lines, which were discovered in 1930 in Peru. The lines cover over 500 square kilometers and include over 50 geoglyphs, with more than 1,300 straight lines and 300 geometric shapes. The lines were created by removing black rock and topsoil to reveal lighter soil beneath and range in width from 6 inches to hundreds of yards. Some of the geoglyphs include animals and plants.
