The Nazca Lines are located in southwest Peru near the modern-day city of Nazca.
They were created by the Nazca culture, who flourished there between 200 B.C.E. and 600 C.E. During those 800 years, the Nazca created a complex of lines and geometric, animal, plant and human shapes on the Pampa Colorada (“Coloured Plain,” or “Red Plain”). The lines and shapes extend over an area of nearly 190 square miles / 500 square kilometers.
Up to now, no one has been able to discern with certainty the cultural purpose and use of the shapes.
But, after flying over them, I think I’ve got it figured out.
