I keep thinking of one of the Jacques Cousteau shows, the one in Lake Titicaca, where they had some old flakey Peruvian bird who claimed that the Inca built tunnels from Tiahuanaco (which is up by the Lake) “all the way to Cuzco” — this was according to the subtitles.
They cut in to Cousteau, with his BS meter going off, staring right into the camera, arms folded. “Cuzco. 500 miles from here.”
Know what, I think it is possible... I wonder if the system they found is level? If it is that may have been how they transported stone. They could have floated it...
Erik von Daniken wrote about those tunnels, “no human technology could...”
Hyperbole Police, but he did print bw pics.
That the lake is 12,500’ is amazing to me. Gonna need to re-jet the Evinrude for sure
