Nazca lines may point to desert water

This is to an article about the ideas of David Johnson, about, quoting the article

The Nasca Lines, ... have been the focus of debate for over 70 years, [and] consist of giant geometric forms (triangles, trapezoids, parallel lines) as well as biomorphs (birds, plants, and mammals) etched into the surface of the desert of southern Peru, especially in the drainage of the Rio Grande de Nasca.

Johnson has been researching these ground drawings since the 1990s, publishing some books about his theory. Some of them are: "The Relationship Between the Lines of Nasca and Water Resources," 1997. "The water lines of Nasca," 1998, "The Correlation Between the Lines of Nasca and Subterranean Water Resources," 1999.

In 2002, together with Donald Proulx and Stephen Mabee, he wrote "The Correlation Between Geoglyphs and Subterranean Water Resources in the Río Grande de Nazca Drainage."

Johnson says that the Nazca lines were a code to tell the inhabitants where the water resources, in an arid region, were. Interesting, and why, is this being written up now, since he has publicized his ideas starting over ten years ago.
