A new research has found that Nasca lines which are a series of ancient geoglyphs located in the Nazca Desert of Peru, may be a giant map of the underground water sources traced on the land, says expert.

The Nasca Lines are located in the Peruvian desert, about 200 miles south of Lima.

The assortment of perfectly straight lines lies in an area measuring 37 miles long and 1-mile wide.

American researcher David Johnson started his research in 1995. He became aware of the scarcity of water in the region and the effect that this had on agricultural production and the quality of life.

While looking for sources of water, he noticed that ancient aqueducts, called puquios, seemed to be connected with some of the lines.

The Nasca plain is one of the driest places on Earth, getting less than one inch of rain a year.

The expert said that a high percentage of potable water of the mountain chain moves through underground filtrations and that the pre-Hispanic population knew perfectly the cartography of water.

He said that lines like the ones in Nasca would be "a language to communicate where underground wells and aqueducts are located".

Johnson has given each figure a meaning: the trapezoids always point to a well. The circles to a place where the fountain is located. And the complex figures as well. For example, the hummingbird points to a giant well with its beak.

These findings have been mentioned in "The Correlation Between Geoglyphs and Subterranean Water Resources in the Río Grande de Nazca Drainage."
