Nasca Holes - The Ancient Spiralling Holes

The ancient strange spiralling holes, known as puquios, are an old system of subterranean aqueducts scattered across the arid valleys of Nasca region of southern Peru which is famous for the vast geoglyphs on featureless landscapes, known as Nasca Lines.

Researchers describes the puquios were a sophisticated hydraulic system constructed to retrieve water from underground aquifers but how they worked has been poorly understood. Using satellite imaging, Rosa Lasaponara and her team from Italian Institute of Methodologies for Environmental Analysis were able to better understand how the puquios were distributed across the Nasca region. Out of 36 Puquios, most are still functioning.

According to Lasaponara research, puquio system must have been much more developed than it appears today. A series of canals brought the water, trapped underground, to the areas where it was needed. Chimneys were excavated above the canals in the shape of corkscrewing funnels. Influx of air through these funnels kept the water moving along the canals, forcing it out into the network of channels in areas where it was needed.

Yet the origin of puquios has puzzled generation of archeologists because it was not possible to use traditional carbon dating techniques. Nor did the Nasca culture, who had no writing system, leave any clues as to their origin.
