The Ancient Aqueducts of Nazca Desert

Dotting the landscape across the dry out valleys of southern Republic of Peru , nigh the metropolis of Nazca , an expanse famous for the mysterious Nazca lines , are large spiraling , rock-lined holes that Pb to an hole-and-corner network of ancient aqueducts. These aqueducts form role of a sophisticated hydraulic organisation containing trenches , tunnels together with wells —known collectively every bit puquios— that convey H2O from hole-and-corner aquifers upwards to the surface for domestic together with agricultural use. Although their historic menstruum is nonetheless debated , the puquios are idea to choose been constructed past times the same people who created the Nazca geoglyphs. Many of these are nonetheless used past times the inhabitants of the valley.

The most visible role of the organisation are the spiraling , funnel-shaped holes called ojos. On the surface of the Earth , the opening of the conical ojos tin last every bit broad every bit xv meters. At the bottom they are nigh a meter or 2 across. Aside from providing access to the H2O inwards the tunnels , they every bit good served every bit entrances to the tunnels for cleaning together with maintenance , a chore that continues upwards to the acquaint day. The wells every bit good allow air current into the canals together with forcefulness the H2O through the system.

The lower terminate of the puquio organisation consists of opened upwards trenches which emerge from the tunnels allowing populace access to the H2O for drinking , bathing , together with washing clothe every bit good every bit a way to channel it for agricultural purposes. These trenches or aqueducts are V-shaped , together with ofttimes lined amongst pebbles to forestall the soil from collapsing. Some of these trenches are every bit broad every bit 10 meters at the go past times , together with every bit long every bit ane kilometer inwards length. Many of the opened upwards trenches empty into small-scale reservoirs which serve every bit wells together with every bit distribution points.

The beingness together with role of these aqueducts choose been known to archeologists for a long fourth dimension , merely their historic menstruum has been a mystery. Because these wells were made from the same materials every bit the surrounding terrain , it is impossible to carbon appointment them.

Puquios get-go appeared inwards historical texts inwards 1605 inwards the writings of a Castilian Catholic priest , which some believe is an indication that these aqueducts together with wells were built past times the Spanish. But at that spot is no testify from Castilian texts to back upwards that. Some archaeologists believe that the aqueducts were built past times Pre-Columbian people to a greater extent than or less 540 CE inwards reply to 2 prolonged droughts during that time. But at that spot is no historical testify to back upwards that either. There is no elevate inwards history nigh either their structure or presence both afterward together with prior to the Castilian conquer of the territory. The aqueducts perhaps every bit one-time every bit iii ,000 years or every bit recent every bit 1 ,250 years.
