Nazca Lines, Peru
The Nazca Lines are large geoglyphs created by the Nazca culture about 2500 years ago. They are located in what is now southern Peru. Amongst the many glyphs are depictions of mammals, birds, and vegetation in addition to linear features likely used for celestial observation. The glyphs are mostly indecipherable in this image, though many other features created by similar earth-modifying processes are highly contrasted against the desert surface. The area was designated a UNESCO World Heritage Site in 1994.
