It's crazy.

But they tell you it's a port, and it was a port on Lake Titicaca, which today is about 10 miles away.

The shoreline is about 10 miles away.

H.S.

Bellamy in the 1800s discovered a strand line that runs basically through where Tiwanaku was.

So strand line is like, you know, basically the shoreline of an ancient water, body of water.

And it can be formed through just gentle wave action over a long period of time.

It can be formed from like a high intensity period of waves, you know, something hammering a shoreline.

But he measured this, he found this shoreline that runs about 400 miles.

So it's like across the Altiplano from Sulastani in the north, way down south towards La Paz.

But he documented this strandline.

What's really weird, and at that strandline, Tiwanaku would have been at the shores of Lake Titicai.

It would have been a small island or a peninsula.

The lake level would have been right there.

And that fits it being a port.

However, the strandline is today, it's tilted.

The strand line's tilted.

So obviously water, when it makes, you know, a body of water, when it makes a strand line, it's flat.

Like it finds its level.

But only geological processes, and I assume over a fair amount of time, can give it this tilt of a couple degrees, which is what they've measured.
