Mysterious Nazca Structures Explained

Nazca holes or puquios have been analyzed by satellite imagery. Researchers now believe they are part of a hydraulic system to retrieve water from underground aquifers. They funneled wind into canals below to move water. They are close to the city of Nazca. The puquios allowed for intensive agriculture in this very arid part of the world. They channeled wind into the corkscrew holes into underground canals filled with aquifer water. The wind moved the water into channels for irrigation. The puquios would date from 200 BCE-500 CE.

The Daily Mail has its usual excellent photos and a silent video here of these structures;
