When David Grann first stumbled onto the story of Percy Fawcett, he wasn't exactly the "Indiana Jones" type. He was a staff writer at The New Yorker with a thinning hairline and a degenerative eye condition called keratoconus. Basically, he was the last guy you’d expect to go hacking through the Amazon. But that’s the thing about David Grann and The Lost City of Z—it’s a story that eats people. It ate Fawcett in 1925, and it nearly ate Grann eighty years later.
Honestly, the whole thing sounds like a fever dream. You’ve got this stiff-lipped British colonel, Percy Fawcett, who disappears into the "Green Hell" with his son Jack and a family friend. They were looking for "Z," a mythical ancient civilization that everyone else said was a total fantasy. Scientists back then were convinced the Amazon was a "counterfeit paradise." They thought the soil was too crappy to support anyone but small, nomadic tribes.
Then Grann comes along. He finds a secret chest of Fawcett’s diaries in a basement in Cardiff and decides to follow the trail.
Why the obsession with Z is so contagious
Fawcett wasn't just some random guy with a map. He was a beast of a man. He could reportedly outlast guys half his age, survived diseases that killed dozens of his porters, and once claimed to have shot a 62-foot anaconda. Whether that last part is true or just "explorer talk" is up for debate, but the man was legendary.
The real hook of the book isn't just the mystery of "where did they go?" It’s the "Fawcett Freaks." That’s what they call the hundreds of people who, over the last century, went into the jungle to find Fawcett and never came back. We're talking about roughly 100 people who simply vanished or died trying to solve the riddle. It’s a literal death trap of a mystery.

Grann’s writing works because he doesn't pretend to be a hero. He’s just a guy from Brooklyn who’s terrified of the bugs. The Amazon he describes isn't a postcard. It’s a place where "even flowers want you dead."
The science that changed everything
For a long time, the "Lost City of Z" was treated like El Dorado—a golden myth for crazy people. But here’s where it gets wild. Toward the end of the book, Grann meets an archaeologist named Michael Heckenberger.
Heckenberger didn't find a city of gold. He found something better: evidence.
In the Xingu region of Brazil, he uncovered "Kuhikugu." This wasn't just a village. It was a massive network of:

- Engineered "garden cities."
- Complex causeways and moats.
- Evidence of "Terra Preta" (black earth), which proves ancient people were actually "farming" the jungle soil to make it fertile.
It turns out Fawcett was right about the civilization, even if he was looking for the wrong kind of "glitter." He wasn't looking for gold; he was looking for a society that had already been wiped out by European diseases before he even got there.
Separating the book from the movie
If you've only seen the 2017 movie starring Charlie Hunnam, you're getting a slightly different flavor. The film is beautiful—shot on 35mm film, very moody—but it simplifies things.
In real life, Fawcett went on eight expeditions. The movie mashes them down into three. Also, the movie's portrayal of Fawcett’s wife, Nina, is a bit more "modernized" than the reality of a Victorian-era marriage. In the book, you get the sense of just how much of a "deadly obsession" this truly was. It wasn't just a hobby; it was a slow-motion car crash that ruined his family's finances and eventually took his son's life.
There’s also the "Dead Horse Camp" mystery. This was the last place Fawcett sent a letter from. He gave two different sets of coordinates for it. Some think it was a typo. Others think he was trying to lead people away from his actual trail so no one would steal his glory.

The Kalapalo oral history
When Grann finally reaches the Kalapalo tribe, he hears their side of the story. They remember the "white man" and his two companions. They say they warned him not to go east toward the "fierce Indians."
The Kalapalo watched the smoke from Fawcett's campfires for five days. On the sixth day, the smoke stopped. They’re pretty convinced he was killed by a neighboring tribe. It’s a blunt, unromantic ending to a very romantic quest.
Actionable insights for your own "research"
If this story has its hooks in you now, don't go booking a flight to Mato Grosso just yet. Here is how you can actually engage with the history without getting eaten by a caiman:
- Read the source material: Beyond Grann's book, check out Exploration Fawcett. It’s a collection of the Colonel’s own diaries edited by his surviving son, Brian. It's biased as hell, but it's a trip.
- Look into LiDAR technology: If you want to see how "Z" is being found today, search for "Amazon LiDAR discoveries." In the last few years, lasers have found thousands of structures under the canopy that Fawcett could only dream of seeing.
- Explore the "1491" perspective: Read Charles C. Mann’s 1491. It provides the scientific backbone for why the Amazon wasn't a "virgin" wilderness, but a managed landscape.
The biggest takeaway from David Grann and The Lost City of Z is that the "blank spaces" on the map aren't empty. They’re just waiting for us to stop being so arrogant about what we think we know. Fawcett was a man of his time—arrogant, tough, and half-blinded by his own ego—but he saw a truth that took the rest of the world a century to catch up to.
To dive deeper into this specific type of historical detective work, your best bet is to compare the archaeological findings of Michael Heckenberger with the descriptions in Manuscript 512, the 18th-century Portuguese document that originally sparked Fawcett's hunt.
