I'd love to know exactly how deep.

Does it say how deep it was?

Because, I mean, that's a significant change in the level of the lake.

So, yeah, Lake Titicaca is 12,464 feet above sea level.

We went and stayed out on an island on the lake with no electricity.

The sky at night was absolutely phenomenal.

If you were a gambler, how old do you think that is?

Yeah, I would put it at least – I'd say at least in that 12,000 to 15,000 years, if not significantly older.

I think – I don't know that there were periods of time in that lake where that level was that low.

What's crazy is that there's been a variance.

There's structures beneath the current lake level.

So the water was lower.

And then we know from the strand line that the water was, God, what is it?

I think 40 meters almost higher than what it is now when it would have been at the shores of Tiwanaku.

Yes.

And the tilted strand line.

So if you were talking about Tiwanaku, if I was a gambler, I would put it at tens of thousands of years.

I don't think – I don't even – and this is speculation.

I don't think it fits even within the 10,000 to 12,000-year cycle.

I think it's got to be tens, like multiple tens of thousands of years for that to be where it is.
