The Nazca Lines are a collection of giant geoglyphs—designs or motifs etched into the ground—located in the Peruvian coastal plain about 250 miles south of Lima, Peru. They were created by the ancient Nazca culture in South America. Scratched on the ground, they number in the thousands and depict creatures from both the natural world and the human imagination. They include animals such as the spider, hummingbird, monkey, lizard, pelican and even a killer whale. Also depicted are plants, trees, flowers and oddly shaped fantastic figures. There also are geometric motifs such as wavy lines, triangles, spirals and rectangles. The Nazca Lines are over 2,000 years old. They can only be fully appreciated when viewed from the air given their massive size. Despite being studied for over 80 years, the geoglyphs are still a mystery to researchers.
