The Largest Ancient Man Made Canal System on Earth

From my Free Web Book 'AncientCanalBuilders.com'

The largest wide-array man made (or at least non natural) structure in the world is in fact an ancient terra formed systems of agricultural-aquaculture canals in Northwestern Botswana and Northeastern Namibia, north of the Kalahari Desert in Southern Africa. Obviously quite ancient, the canal systems no longer provide free flowing water throughout its 105,000 mile array, but many sections show obvious intention to provide cross sectional irrigation.

These canals are too evenly spaced over too large an area to be any kind of natural formation. Based on entry and exit points, it is readily apparent this system is a very large, controlled agronomy array and/or aquaculture system. Its age is defined by the overgrown nature of the canals, as well as some areas that are covered over with drift and sand erosion.

The entire complex covers an area about equal in size to the State of Arizona in the USA. The canals are an integrated system of apparent irrigation and agricultural (and probably aquaculture) design. The system is about 350 miles in width and about 300 miles in depth. (For the remnants still visible.) This system represents roughly 67 MILLION acres of sustainable agriculture. Given the sophistication of design, it is entirely plausible to assume an above average yield, i.e. feeding well over 90 persons per acre on an annual basis. The system may or may not have provided a sustainable aquaculture (marine farming) environment. I have no reason to suspect that it did not.

Given the size and scope of this complex, (canals are about 1 mile apart on average) and collectively are roughly 350 X 300 miles in a rough rectangular format. (At least the observable parts) There could be, and probably is, much more to this complex than what is visible to the naked eye. Right now, we can identify ancient cultivation of roughly 105,000 square miles.

One square mile = 27,878,400 square feet, or 640 acres, so the entire complex had a sustained producing land mass of (640 acres x 105,000 square miles) or > 67,200,000 acres. (That is 67 MILLION acres)

One linear mile of canal had (750' width x + >12' depth x 5,280') = 47,520,000 cubic ft of water per linear mile.

Entire canal length (105,000 miles x 47.5 million cubic ft per mile) = 5,000,000,000,000 (That's 5 TRILLION) cubic feet of water in the canals. It would be an incredible waste of time and effort to irrigate >105,000 square miles of sustainable agriculture land, and not use the 5 trillion cubic feet of water circulating in the canals for aquaculture farming. I don't think the builders were that stupid.

Different estimates of the numbers of people this sustainable system would supply varies widely, though it is generally accepted that a system like this, if properly managed would provide a complete annual diet for somewhere between 60 to 120 people per acre. Which means this system was in fact providing food for an average of about 5 Billion people.

This array is in fact the largest non natural artifact on the Planet. It can be clearly viewed unaided from the International Space Station at roughly 230 miles up, which cannot be said for any other non natural feature on Earth.

I would suggest that depth of canal(s) must have been significant to compensate for general slight variations in elevation. There seems to be an average elevation variation of about 60', sometime more, and sometimes less.

First brought to my attention by Gary Schoening Here is his original Vimeo post: http://vimeo.com/64351951

[Photo wide area of "petroglyphs", etc.]

And Pisco Valley, Peru. More "natural erosion". Length: approximately 1,450m; Width: approximately 20m; Number of holes estimate: 6,900

IMO, too many anomalies are written off as "natural" and I think part of it is due to people advancing theories that have gained even slight acceptance. They in turn become solidified as Holy Writ and all efforts are directed to defending that theory, to the point of ruining peoples' careers. Then the major protagonist dies and those who no longer have to fear of being ostracized as heretics, come up with an alternative, and usually a better interpretation.

Some wag, familiar with that dark side of science, opined that science progresses from funeral to funeral.

I think he's on to something.

...any hint of when they think the system was either created or last in use???

The blogger mentions a book, maybe he provides more information, I do not know. It all seems to be a rather recent Google Earth find, like Vernuekpan.

Earth May Have Created Its On Water Deep Within and There's Still Enough There To Fill the Pacific

It doesn’t appear that the “researcher” has ever been to the site. It looks like the entirety of his research was done on google earth. I see he complains about geologists so he apparently asked one but didn’t like the answers he got.

I would want many dozens if not hundreds of core samples from the tops of the ridges to the bottoms of the valleys all across the region.

The guy makes global warming science look downright professional.

[Fred Nerks]

What I do not understand is the pressing need for an explanation, the ‘thing’ is there and nothing changes the object regardless how mundane or fantastic the theory. We are looking at the results of some so far inexplicable phenomena which have been there for possibly thousands of years. If they remain a mystery for another century, so what?

Google Earth is showing us how much we have not been able to see before.

Lots of terraces, very few are salt:

I had heard that one of the problems with irrigation canals is that salt can accumulate over time, so I thought maybe the same problem could occur with terraces. If that were the case then maybe that would explain the huge numbers of terraces all over the place in south America - they were forced to abandoned ones that had become unusable and build new ones.

[Yardstick]

Pretty wild. I’m surprised this formation isn’t more well known.

After further research I am wondering if those lines are this

http://en.m.wikipedia.org/wiki/Lake_Makgadikgadi

I get mad at my brother who buys into ancient aliens and similar crap. They put together this seemingly cogent line of thinking with seemingly infallible facts. The problem is they often either outright lie or stress the facts. Lime Pumapunku. They state its 12000 years old and could only be carved with a laser. Its actually 1200 years old and made out of red limestone, which doesnt even need metal to carve.

‘The guy’ is showing you what he sees on Google Earth, just as someone else showed what he saw in the Vernuekpan dry lake; he makes some assumptions which you can ignore, just like you can ignore the supposed purpose of the numerous canal systems throughout South America and Mexico. However, who created them and for what purpose remains open...

[cripplecreek]

Puma Punku is a pretty astounding site. I’d love to know how the locals did it but they’re gone now.

[TigersEye]

From that view it would appear that the Okavango Delta is the drainage point from the suspected canal system. Just spitballing but perhaps the system collapsed when the lower end, the Okavango, catastrophically gave way and drained the “farm.”

[Fred Nerks]

... I’m surprised this formation isn’t more well known.

Have you heard of Vernuekpan before? It's far more complex and was only discovered recently.

no sign of salt anywhere...

[rdl6989]

Just glancing at the title I guessed the Hohokam indians of Arizona, but I guessed wrong.

[smokingfrog]

The Makgadikgadi Pan, a salt pan situated in the middle of the dry savanna of north-eastern Botswana, is one of the largest salt flats in the world. The pan is all that remains of the formerly enormous Lake Makgadikgadi, which once covered an area larger than Switzerland, but dried up several thousand years ago.

... entirely possible!

I love it, if it was you are right... the rest of the evidence would be there. The parked equipment used to do the trenching, the maintenance equipment, the sheds, the pumps/valves control systems, the source of the water, the harvesting / processing/storing facilities. The residences, the social infrastructure..... government structures, libraries, museums,..... streets/ streetlights....etc etc.

All those things would be visible.

In the absence, it’s all horseshit.
