new to me, and very interesting.. did a quick search on this and did not find a whole lot tbh..
however i did come across this article about ancient irrigation canals in the Zana Valley
A team of researchers working in the Andean foothills of Peru has unearthed solid evidence of canals confirmed to be at least 5,400 years old. The
find is the oldest of its kind anywhere in South America.
Led by anthropologist Tom Dillehay of Vanderbilt University, the scientists' work in Peru's northern Zana Valley exposed four canals almost certainly
used for irrigation agriculture. While their location was originally discovered by Dillehay and his team in 1989, only in the most recent field season
did the importance of the canals become apparent.
The canals range in size from 0.6-2.5 miles (1-4 kilometers) in length and were designed to slope downwards, relying on gravity to send water from an
upper stream to the crop fields below. The layout essentially created artificial garden plots with fertile earth suitable for intensive
It is this more concentrated form of cultivation that allowed societies to flourish, according to Dillehay.
"The construction and maintenance of the canals on an annual basis, along with the planting, weeding and harvesting [by] groups, all required a steady
communal or corporate effort," Dillehay told LiveScience. "These sorts of activities can be carried out by consensus among households, all of which is
clearly there was sufficient population and organisation in the area to construct and maintain the geoglyph, and one could speculate that along side
the canals (the most ancient in the americas) it was an to ensure the success of their crops.
This geoglyph is from the 1st millennium bce according to the book featured in the above link..... cant run google earth on my abacus so not sure how
close the canals are to the geoglyph or if the folk responsible are from the same culture... the canals would possibly no longer be in use by the time
the glyph was laid out though from a scan of the pages around the link above the place was fairly active population wise and
culturally/technologically at this time. most interesting
