And so he had a great admiration for these people. And he wanted to try to find a big, big civilization, something with enough people that could rival Europe. And where he went missing was in the Mato Grosso region of Brazil. And and the last place that they know that he was at was on May 29th, 1925. And he wrote a letter to his wife from Dead Horse Camp.

And he was like, it may be a while before you hear from me. It could be up to a year or two before you hear from me. I'm about to head into a very dense area. And my trail runners who would go back and forth with his notes, they weren't going to follow him out there because it's too dangerous. And that was the last letter that he had written.

And he was going – he was heading off into what's called the Zingu region, which is like the Zingu River. And it's one of the most hostile regions in the Amazon. Maybe even today. Teddy Roosevelt had trouble when he went there. But the Zingu region is – is where all of the major LIDAR came out within the last 10 years. They found all the ruins of these giant cities.

And there's a city called Kiriguyu, I think. And it had an estimated population of about a million people, which is the size of Rome. And, you know, when you look at the LIDAR images, you can't get a perspective of how big they are. I have access to a LIDAR database of the entire United States, and I've mapped all kinds of huge uncharted mound sites in Florida, all of the southeast.

I have hundreds of sites marked. And when you first look at them on a map, you're like, oh, okay, maybe that looks like it's 50 feet long or something. No, they'll be like 300 yards long, like these giant raised platforms in the middle of the forest here in the US.

And if I had access to LIDAR data like that, where I could measure it down on the Amazon, some of these things are miles long, like raised platforms are a mile long, and they have highways. Maybe we should pull up just an image of a LIDAR scan from the Amazon. But you'll see this central city area. You'll see step pyramids and raised platforms.

Maybe this is where people lived or maybe this is where the market was. And there will be a road that cuts straight through it. And you can see the road just goes off in the distance for miles and miles and miles. And so what they would do. Here we go. Yeah, this is so this is one of these sites in this one of these sites. I believe this is in Brazil or maybe it's in northeast Bolivia.

And is all that area covered completely with jungle right now? Completely covered in jungle. Yeah. So if you went out there- You wouldn't see any of this. You may not realize that you were standing on a mound. You really got to train your eyes.
