Ye Olde Grouch has been called,
and thus it is now time for me to become Ye Old Grouch.
Before one starts babbling about Atlantis, "Pole Shifts", aliens, and a lot of other theosophist bullshit, or "experimenting" with ayahausca "tourism", it would help to do real research work in the real world first.
First buy some reliable academic books by professional archaeologists and read them.
One could then start field work by looking at the robbed stones used in building La Paz, tracking them down, and tracking down the colonial records of their removal from their original sites.
Locate the quarries for the stones, and study them.
Keep an eye out for the remains of quartz tools and other tools.
Locate the ancient peoples's copper/arsenic and nickel sources.
As far as transporting large monoliths goes, there is stone rowing.
Accept the radiocarbon dates, and any astronomical misalignments ascribe to the ordinary tectonic activity of the area. Try to date that activity reliably, please.
I would hope this helps, but since fantastic bullshit is so much more fun, makes some people feel so good about themself's and their importance here on Earth, and sells so well,
I doubt it.
Do all of the work first, and please don't bother me with your bafflement until you have.
Or else Ye Olde Grouch will return.
And please, please don't use these remains to sell any religious beliefs you might have.
Feel free to chew coca and drink coca tea during your high altitude work,
but stay to fuck away from dealing/smuggling coke.
As far as the ayahausca goes, remember those headless bodies first.
By the way, the local traditions regarding Pukara are in "Man and Impact in the Americas", including material on the jaguar cults of South America.
The nickel rich iron meteorites of Campo de Cielo are not covered in this edition.
