First time I have seen this:
Nazca plotted over the globe
Ankor maps celestially to Draco .. Dragon lines? The original straight tracks?
Anyone doing this was flying Vimanna, or better.
This was farther back in the way back machine, its way, way back . . But a culture doing this, would have no issue with aggregate, . . .
Let me suggest the HHO torch for the vitrified places . . It is possibly driven by water + catalyst in those days . . It may be the item carried by the statues near the Gate of the Sun, and one of these was found underground in a deep gold mine, in the area of Africa where Tellinger notes there are very deep mines . . . It was reported as terrifying (embedded fear em?), and was sufficientto keep them from exploring a tremendous find. ...
The Igigi miners? (If you allow Sitchin.)
At any rate, this allows your knowledgw to have a world wide perview, without even worrying about navigation by boat.
Mind is the rider.
