I guess he found the lost city of Y and didn’t ever get to Z.
Actually, I read that book Lost city of Z, was really really interesting.
They were going to make it into a movie, with Brad Pitt, I think was going to play Fawcett, but it got shelved.
Seems it’s coming back. Hopefully, but without the Pitt.
