This well-illustrated text provides Nasca Lines enthusiasts, researchers, tourists and coastal residents of Peru and Chile with an exciting new theory for one of the functions of the coastal geoglyphs of Peru and Chile. The author’s research, undertaken over a period of 12 years, also broadened our knowledge of the region’s geology, hydrology and archaeology.
In 1996 while locating groundwater sources near Nasca, Peru, David Johnson realized that aquifers (areas of higher permeability), which were not recorded in modern times, crossed the Atacama Desert. As he documented these aquifers he realized that most of the ancient Nasca Lines (geoglyphs) documented their flow patterns. By studying the correlation between geology, hydrology, archaeology and the geoglyphs, he realized that geoglyphs could be used to locate aquifers. During the initial investigation he collaborated with scientists from the Geosciences and Anthropology Departments of the University of Massachusetts.
Then he applied his theory to other valleys along a thousand miles of Peru and Chile’s coastal desert, discovering dozens of previously unknown geoglyphs. These new geoglyphs are described for the first time in this text. Johnson’s interpretation of the coastal geoglyphs provides a practical function for their construction which is being applied today, as it was in the past, to find the most important component needed to support life in this parched environment, water. The author has successfully discovered new water sources in a number of locations in Peru and Chile using geoglyphs as his guide, providing a practical application of these studies for the contemporary populations of this arid region. This text covers the discovery, research and conclusions based on over a decade of research.
All of the data gathered during this survey has been placed in a “My Places” file which can be brought up in Google Earth. Therefore as one reads the text they can bring up each site in Google Earth and examine the location in detail. However readers without access to Google Earth can still follow the story by examining numerous photographs and maps which accompany the text and gain valuable insights without using this application.
