And this is, you know, thousands of years old, but...

It's a remarkable site full of these sort of examples, and it's attributed in general to a culture that lived there around 1100 AD.

They're still digging stuff out of the ground.

It was destroyed in a cataclysm or just some sort of massive mud flood, I think, was the end of this civilization.

However – that's me and Graham –

And this is at 12,000 feet?

12 and a half, yeah.

It gets strange because there's – so the modern – first, the modern dating for it –

It comes from a handful of carbon dates, right?

They found some carbon dates and they go, okay, 1100 AD.

But they've also found carbon dates that go back to 1500 BC and they just dismiss them as being unreliable.

I literally think these carbon dates could literally be the last person someone lit a campfire there or was buried there.

There's a guy named Arthur Posnanski.

He was a Polish professor that lived.

He spent 50 years on this site, died in La Paz, published his works, 1945.

I have a copy of his books, The Cradle of American Man, it's called.

He spent 50 years investigating this site.

He dated it at 15,000 B.C.

based on a whole range of other geological data, astroarchaeological dating, which it has these alignment properties we can talk about.

He found the skull of a toxodon there, which toxodon is an extinct Pleistocene-era mammal that went out in the Younger Dryas, 13,000 B.C.
