Yeah, I have a Tiwanaku directory there, Jamie.

And it's quite well preserved because it was buried in mud.

It's slowly been excavated.

And there is a lot of evidence that suggests this place is at least 10,000 to 12,000 years old, again, using...

The H blocks are famous at this place, but they just have these endless little insets and stuff like this.

This is one of my favorite blocks to show people.

You're looking down on top, so the ground's down.

So I'm looking down this thin channel that's been cut into this block, and it has all of these little drill holes in it.
