The largest geoglyph is a 935ft-long pelican. Most of the lines are formed by a shallow trench with a depth of between four inches (10cm) and six inches (15cm), made by removing the iron oxide-coated pebbles that cover the surface of the Nazca desert to expose the light-coloured earth beneath
The Nazca Lines, Peru - Created thousands of years ago, the “Nazca lines” are a series of gigantic figures sketched across the desert sands in Peru. They were made by scraping red pebbles against the ground, revealing a lighter-colored sand beneath. Other than the method of their creation, however, no-one knows the figures’ meaning. In fact, they were not discovered until the 1930s, when pilots and passengers noticed them.
Nazca Lines in Peru were created by the Nazca culture between 400 and 650 AD. The hundreds of individual figures range in complexity from simple lines to stylized hummingbirds, spiders, monkeys, fish, sharks, orcas, and lizards.
