The mystereous Nazca Lines were most. probably created during the days of the Nazca culture, from 500 BC to 500 AD.

The mystery is not so much how the lines were made, but what was the purpose. Theories aplenty, but the fact is nobody knows, and that  makes these lines so mystereous.

Most of the lines are just that, but there are also intricate figures of animals, humans and trees. And the figures are large, some measure up to a few hundred meters across. 

 

The Nazca desert is extremely dry so everybody was afraid for major damage when rare flashfloods and mudslides occured in 2007. It turned out that there was more damage to the modern roads than to the ancent lines. But recently Greenpeace and the Dakar Rally did manage to cause some damage.

 

In September 2007.we flew over the Nazca lines.
