And in fact, when I was there, literally like two weeks ago –

We made some observations that I hadn't made there, but I'd spent a bunch of time at Tiwanaku over the years.

But we figured out that those big pillars of that callus acai, we thought they were andesite, they're granite.

The ones on one side, they're actually granite and they're very heavily eroded.

Again, you have that big scoop out of it.

You can see the bottom where they were buried.

But there's this huge amount of erosion, and granite erodes way more slowly than things like limestone.

So I think the erosional data there needs to be studied, because I don't know how long it would take, even in that environment, which gets more rainfall than places like... It can rain quite a bit, you get these storms.

But I think it takes a long time to erode granite that far.

And...

Um, the stuff that's been exposed and above, you know, the, the mud.

And when there was, it was clearly some sort of big mud flood that came in that, that knocked this stuff down.

Uh, the stuff that was been faced down or buried in the mud has been quite well preserved and protected, but.

There's like one minute of underwater footage.

That's Inca.

Whatever that is, it looks Inca.

Yeah, gold Incan figurine.

Well, the Inca were definitely there at the lake.

There's the island of the sun, island of the moon.

That's Inca.
