Oh, I thought he’s just gotten lost deep in the jungle (presumably looking for the free pizza that was left over from the undergrads’ seminar). But wow, 16’th page of Google, that really is uncharted territory.
Since the 16th page of a google search is usually the end of the third repetition of the first four pages of a google search, he'd probably already missed it three times...

Only slightly less difficult than hunting down an obscure Reddit thread that is improperly red-black balanced 15 nodes in from the root and still 10 nodes away from the leaf.
Based on the images, I think that the largest structure is about here: 18.891548°N, -89.323622°E. But you can't see anything in google earth (otherwise why would he have had to traverse 16 pages of google search results).
The larger of these are definitely not "lost" (as in, local people who are the descendants of their inhabitants have known exactly where they are, continuously since they were abandoned as places to live a millennium ago), though most of them are in the middle of the jungle.
Southern Mexico and Central America are incredibly beautiful though, and ancient ruins there are fascinating places to visit.
Tulum for example was never "lost." It sits directly on the coast and it was "found" by Europeans (from a ship!) in 1518. The local Maya people knew exactly where it was.
Today the Maya still live in the area and they support their families by working in the tourist industry.
Since we're going there...Graham Hancock's a philistine but I'd take his word over somebody like Flint Dibble. Dibble lied and pushed off bad information to win a debate and he did a disservice to himself and his peers. Many of whom work thankless jobs out on remote sites with no health insurance and for pitiful wages. They shouldn't be represented by a smug arrogant conman that passes off irrelevant studies on metallurgy, outright lies about ship wrecks and has to name drop and smear the civilians at any chance (I'd like to see that 15th century drawing of an island orthorectified like it's an image captured from a multispectural sensor Mr. Rogan)
Wow, thanks for this info. It's incredible how much weight podcasts such as these provide to people who are basically either liars or just plain incompetent.
This link: https://i.redd.it/gm8273jvjrk71.jpg is an map (outdated though, it dates to 2019 AFAIK) of how much of the Earth's surface has been mapped by google street view.
Is there a similar map product that shows how much of the Earth's surface has yet to be surveyed with lidar (or a suitable equivalent)? I would assume that areas with zero vegetation can be covered by satellite imagery but it is possible that the resolution is poor (for example, SRTM had a 30m resolution).
That map, while interesting, seems entirely subjective - the whole appearance of the map can be determined by the thickness that you set the street view lines to, no?
I guess you just lose the ability to distinguish between areas past some density, right? What would be a good way to improve it… maybe apply some filter, Lanzcos or whatever?
The technical term is "viewshed analysis", what areas are visible from a given set of points. Any competent GIS system will have ways to do it, but peakfinder.com works pretty well as a more visually interesting demo.
Guess I didn't read the parent closely enough. Thought it was asking what the best way to figure out the actual coverage without arbitrarily increasing line width as you zoom out.
I've been watching the Ancient Apocalypse (S2) on Netflix and I had similar thoughts on discoveries. With drones and lidars we can discover so many of these villages/towns/cities, but the challenge would be to actually send boots on the ground and excavate into getting meaningful data/findings.
At the same time, the baddies (grave robbers, looters, etc.) can use the same tech and beat us to the game.
It won't be visible to the naked eye. Maya ruins like these are covered by centuries of overgrowth. Lidar scans can spot shapes buried under this overgrowth, but from the air it'll at best look like random hills of dirt.
Maybe if there are structures comparable to Calakmul (which is close to Xpujil), you'll see some rocks on a tall hill.
I mean if you have the coordinates? And it’s 15 minutes away, why would you need Lidar or drones? You could probably send in some inquisitive geeky nerds from the local schools to scout it out.
for a $500 plane ticket and a 4 hour drive, seems like someone has surely gone there by now, just to ground-truth this. Otherwise, seems like a fun (with plenty of risks, obvs) way of being "the first" to lay eyes on this.
I'm guessing you've never actually been in "the jungle". It's not hospitable at all.
The other thing is that that area of Mexico is just teeming with this stuff. There's just an untold boatload of "lost cities" in there. They can't dig and map the stuff they are working on, much less any of the numerous finds that have been made in the past 10-20 years.
A good chunk of Central America is like this. One person I know maintaining maps of historic Maya settlements was tracking thousands of known names, most of which were positionally located by rough distance estimates from some other coarsely located feature. Many didn't even have that, just a name in some historic document.
That's kind of like finding ancient stuff in Greece. You dig a hole, and there's some ancient pots and pans in there. It's gotten to the point where people who want to build houses just carry the ancient findings away in the night, because the antiquities service will otherwise deem your plot an archaeological site.
This type of thing happens in most countries. In the USA they actually have to hire bored archeologists to check things out as part of any contract from the federal government (and a lot of state governments) on anything that might have a hint of Native American relics.
It's sad if "lost cities" are becoming so common, that they're losing their romantic-exotic-intrepid charm. If lost cities ain't got it no more, what in this world does?
I love the idea that there might have been fully technological civilizations of humans on earth that have been totally lost to time. I know that the Maya were not that, but go back 10,000 years maybe, who knows?
Dinosaurs lived on Earth for about 100,000,000 years, at least 50 times as long as our species. Perhaps some dinosaurs were the most advanced species our planet has ever seen.
I read a stat (maybe not true?) that we've only found around one dinosaur fossil for each 10,000 years that they existed. Maybe we just haven't found peak dino society yet-
if you broke humanity down into one archaeological find per 10k years you probably wouldn't think we had much of a society either.
Most of the time, dino bones don't fossilize. And we only find some small fraction of the small fraction that do. But with glass and ceramics the situation is different. Those are stable in almost all conditions, running water excepted. A beach will break down a coke bottle in a few years but if it lands just about anywhere else it has a high chance of lasting basically forever.
If dinosaurs ever became like us, there should be a clear layer in the rock where they started throwing their trash on the ground.
If dinosaurs had changed their environment as much as humans, there would probably be more than the occasional fortuitously preserved corpse or footprint to find.
They lived so long ago, my understanding is such artifacts would be extremely unlikely to survive. We also haven't looked in that many places at that depth.
Maybe not full-blown technology, but a lot of New World philosophy, art, and mathematics, and history were destroyed by the Europeans or otherwise lost to time. Maybe even medicines that we don’t know about. They didn’t have electric computers though.
I'm not sure what "fully technological" means, but if they had made anything at scale out of durable materials like stone or ceramic we would most likely have seen some indication.
What we do probably underestimate is how advanced ancient hominids were. They mostly worked with materials that decay like wood, plants, and animal skin. But we're slowly learning that they were more advanced than we used to believe.
Any former civilization that is any sizable fraction of ours with same level of tech would have been spotted long ago. Well unless Atlantis is real somehow sunk 3 miles down
An interesting theory (albeit likely sci-fi) is that on a long enough timescale, any existence of an advanced precursor society will have been lost by tectonic plates sliding down. But that's a timescale of hundreds of millions of years (apparently the earth is ~4.5 billion years old, human life that left traces of intelligence behind is a percentage of a percentage of that)
You mean like the Aztecs (and other civs) before them? Humans gonna human. I think we have to always look at the whole story and not just what’s currently popular to demonize.
Their actions were still unique in many ways. And the Spanish’s action were an order of magnitude more consequential. The Aztecs warred and pillage other groups but were not in the business of wiping centuries of knowledge off the face of the earth nor did they ever manage or desire to kill 90% of all peoples of central Mexico.
Considering that the seas were hundreds of feet lower, and most settlements are built on coasts and waterways for transport and food harvesting purposes, it is very likely that anything left before the last ice age was destroyed by rising seas and any remnants are far offshore.
Yes, it would be a sobering reminder on how essentially powerless we are in the face of global calamity. You see this recognized in religions and in pre-technological societies, but few of us in the modern era do.
That means we squandered almost 10,000 years of human history before humans became an advanced civilization. We could have invented flight, discovered antibiotics, etc five thousand years ago.
Most of the clocks we’re racing against are ones we invented in the last 200 or so years. So the other 9,800 years weren’t really squandered, the clock really wasn’t ticking so much back then.
Squandered implies it was somehow a meaningful loss, at least that’s how I interpreted it.
It was meaningless time. If we’d gotten to our current development level ~5000 years ago, we’d just be writing these same comments next to calendars that had their zero sent to ~7000 years ago.
We still wouldn’t be alive 5000 years ago. That part doesn’t change. I think you’re confusing yourself.
Half of Europeans that died during the great plague would’ve benefited, for example. Most people who were born in the past 150 years would still be alive.
I’m not at all confused. But we’re somehow talking past each other. Which I probably contributed to too, although that wasn’t my intent, so sorry for the mix up. Anyway, it is just silly chitter-chatter so I think it is not worth sorting out where we’ve missed each other.
You’re taking a radically different past, and then somehow arriving at the conclusion that any part of history that we current know would have still happened.
No, I’m assuming we had an advanced civilization 10,000 years ago then assuming continuous progress was made.
I threw out the Great Plague, or something similar, as an example of something that wouldn’t have occurred because science would have addressed these types of diseases. Covid today would be easily treatable in a more advanced society
Clearly history wouldn’t play out the same way. The point is that today’s society would be much more advanced
“I was on something like page 16 of Google search "
whoa, I had no idea there were that many pages in a google search. that's some serious googlefu to get that kind of a result. I guess it definitely says something about the researcher too to continue on that deep.
I'm expecting that comment to have been hyperbolic though
I have friends who work in InsuranceTech and they use satellite images of houses when someone apply for home owners insurance. They've said it flags people with trampolines all the time.
My insurance company asked about that when I got the policy, I said Yes we have one and it was not an issue. Perhaps they are charging me a higher premium, but not enough that I noticed.
Though we no longer have it, so perhaps I should mention that next time I meet with my agent.
How is this by accident? He was specifically looking for datasets for this purpose and found a good one, then loaded it into a program to find man-made structures.
How many cities are lost every year? Can finding those cities help alleviate the housing crisis? Won't the inhabitants of those cities complain about disrupted postal service? I have so many questions!
Can the locals draw a map of these lost cities? Or are they just aware that there are many lost cities, but without knowing exactly where they are?
And for that matter, if the locals did know the specifics but weren't spreading that knowledge, then it still can constitute a discovery.
"Discovery" can mean revealing knowledge that was previously known to insiders, eg. if I say "I discovered an underground smuggling ring and reported it to the police", you probably wouldn't argue that "you didn't discover anything; the smugglers already knew about it".
>"Discovery" can mean revealing knowledge that was previously known to insiders, eg. if I say "I discovered an underground smuggling ring and reported it to the police", you probably wouldn't argue that "you didn't discover anything; the smugglers already knew about it".
Just wanted to say how much I'm enjoying this point.
Newspaper Headline:
Discoverer of Underground Smuggling Ring Proven a Fraud: Ring Leader Says He Discovered It First"
Wow archaeology should be rife for disruption if you can just go around and ask locals. Seems like anyone with gumption could be the next great scientist.
Or maybe one of those locals could be. I wonder what stops them?
> Or maybe one of those locals could be. I wonder what stops them?
They're living their lives, rarely becoming academics in the relevant field, assuming that local rock ruin is known to somebody outside of their community, or if not, then assuming nobody cares anyway.
You can probably find a lot of undocumented ancient stuff by asking shepherds in areas known to be territory of ancient poorly documented civilizations.
What is the proportion of villages where surveying the locals will lead to documenting an abandoned city that is otherwise only known to the locals?
If only 2% of villages have an undiscovered profitable heritage, then 98% of surveys will show no results, which makes it difficult for anthropological surveys to compete with lidar for grant funding, especially when lidar is still new enough to seem "sexy" and "sci-fi".
To put into context how few funding dollars there are in archaeology, the NEH currently has $800k available for archaeological field research proposals. That's the largest "funding agency" pool for generic field research.
This same funding agency that doesn't directly fund computer research also has $2.5M available for proposals specifically targeted to starting collaborations researching AI alignment. They have another $3.5M for the actual collaborations themselves, and an additional $2.2M for AI work that "contributes to scholarly research in the humanities".
How about “discovered it for the world at large” I think there have been many cases where the locals knew about a lost city or even took stones for their farms from it for X purposes. Still it lets the government there know about a new lost city they can properly check out (or leave alone)
"Discovery" probably isn't the right word, but the important part isn't knowing that something is there, the important part is telling the rest of the world about it.

At last count, we had 8 billion people on the planet. I think it’ll be fine if some people do space while others work on oceans.

Throw a stone and you'll find a lost city in Mexico. Lost cities found so far: Acanceh, Aguada Fénix, Aké, Balamku, Balankanche, Becan, Bonampak, Calakmul, Chacchoben, Chactún, Chicanná, Chinkultic, Chichen Itza, Chunchucmil, Chunhuhub, Chunlimón, Coba, Comalcalco, Dzibanche, Dzibilchaltun, Edzna, Ekʼ Balam, Hormiguero, Izama, lIzapa, Jaina, Joljaʼ, Kabah, Kiuic, Kohunlich, Komchen, Labna, La Mar, Mayapan, Maní, Moral Reforma, Muyil, Ocomtún, Oxkintok, Palenque, Plan de Ayutla, Pomona, Punta Sur, Río Bec, San Gervasio, Sayil, Tamchen, Toniná, Tortuguero, Tulum, Uxmal, Uxul, Valeriana, Xcaret, Xelha, Xlapak, Xpuhil, Xtampak, Yaxchilan, Yaxuná, Yula, Yoʼokop.
The larger of these are definitely not "lost" (as in, local people who are the descendants of their inhabitants have known exactly where they are, continuously since they were abandoned as places to live a millennium ago), though most of them are in the middle of the jungle.
Southern Mexico and Central America are incredibly beautiful though, and ancient ruins there are fascinating places to visit.
Tulum for example was never "lost." It sits directly on the coast and it was "found" by Europeans (from a ship!) in 1518. The local Maya people knew exactly where it was.
Today the Maya still live in the area and they support their families by working in the tourist industry.
Calakmul is so cool’s. So is the nearby volcano of the bats.

Lidar has been finding a lot of lost cities.
Not discounting this finding. It's just becoming more common.
I've been watching the Ancient Apocalypse (S2) on Netflix and I had similar thoughts on discoveries. With drones and lidars we can discover so many of these villages/towns/cities, but the challenge would be to actually send boots on the ground and excavate into getting meaningful data/findings.
At the same time, the baddies (grave robbers, looters, etc.) can use the same tech and beat us to the game.
National Geographic even created a TV show 5-years ago specifically on this topic.
"Lost Cities with Albert Lin" (2019)
It's an 11-episode show where they use Lidar in each episode to find lost cities.
https://www.imdb.com/title/tt10366494/
That drivel got a second season?
That you Flint?
Nobody has a more appropriate name than that man.
"It is just 15 minutes hike from a major road near Xpujil where mostly Maya people now live."
And nobody sent a drone yet? The BBC has a jungle drone team.[1]

It won't be visible to the naked eye. Maya ruins like these are covered by centuries of overgrowth. Lidar scans can spot shapes buried under this overgrowth, but from the air it'll at best look like random hills of dirt.
Maybe if there are structures comparable to Calakmul (which is close to Xpujil), you'll see some rocks on a tall hill.
We can look forward to the Instagram video, "With machete and weed-whacker".
I mean if you have the coordinates? And it’s 15 minutes away, why would you need Lidar or drones? You could probably send in some inquisitive geeky nerds from the local schools to scout it out.

https://pbfcomics.com/comics/dinosaur-meteors/
Sadly there's basically zero chance of that. We don't find dinosaur pottery sherds or cola bottles embedded in sedimentary rock anywhere.
I read a stat (maybe not true?) that we've only found around one dinosaur fossil for each 10,000 years that they existed. Maybe we just haven't found peak dino society yet-

Maybe dinosaurs were just more advanced when it came to building a society that coexisted with their environment
Yeah, there should be some sort of world wide epoch shifting environmental change about 65 million years ago to show for it.
I'd be more impressed with a fossilized dinosaur port, motorway or garbage dump than a crater in the Gulf of Mexico tbf...
They didn't make pottery but they had very intellectual conversations and some very good philosophers
They lived so long ago, my understanding is such artifacts would be extremely unlikely to survive. We also haven't looked in that many places at that depth.
I mean it's still quite unlikely though.
If bones survived, some advanced remnants would also survive, I would expect.
Well, survived by turning into rocks: https://ucmp.berkeley.edu/paleo/fossilsarchive/permin.html
Gah, wrong comment responded to.
Maybe not full-blown technology, but a lot of New World philosophy, art, and mathematics, and history were destroyed by the Europeans or otherwise lost to time. Maybe even medicines that we don’t know about. They didn’t have electric computers though.

An interesting theory (albeit likely sci-fi) is that on a long enough timescale, any existence of an advanced precursor society will have been lost by tectonic plates sliding down. But that's a timescale of hundreds of millions of years (apparently the earth is ~4.5 billion years old, human life that left traces of intelligence behind is a percentage of a percentage of that)
Its the ocean plates that slide down when they hit the more buoyant continents. When continents hit they make the Himalayas.
The conquistadors praised Tenochtitlan, viewing it as an advanced city equal to the Spanish cities of the time.
Hey muchachos, I think 5 minutes of praise for Tenochtitlan is in order.
Right, that's that done, now, onto the 3 centuries of murder, rape, pillage, inquisition, and subjugation.
You mean like the Aztecs (and other civs) before them? Humans gonna human. I think we have to always look at the whole story and not just what’s currently popular to demonize.
Their actions were still unique in many ways. And the Spanish’s action were an order of magnitude more consequential. The Aztecs warred and pillage other groups but were not in the business of wiping centuries of knowledge off the face of the earth nor did they ever manage or desire to kill 90% of all peoples of central Mexico.
The floating city would've almost certainly been a marvel in its own right.
Considering that the seas were hundreds of feet lower, and most settlements are built on coasts and waterways for transport and food harvesting purposes, it is very likely that anything left before the last ice age was destroyed by rising seas and any remnants are far offshore.
Is "love" really the right descriptor here? The implications are truly depressing.
No need to get depressed about an idea with zero evidence.
Considering what terrible stewards of the the Earth and of each other we are, depressing is also a wrong descriptor.
Yes, it would be a sobering reminder on how essentially powerless we are in the face of global calamity. You see this recognized in religions and in pre-technological societies, but few of us in the modern era do.
That means we squandered almost 10,000 years of human history before humans became an advanced civilization. We could have invented flight, discovered antibiotics, etc five thousand years ago.
Most of the clocks we’re racing against are ones we invented in the last 200 or so years. So the other 9,800 years weren’t really squandered, the clock really wasn’t ticking so much back then.
That sort of makes absolutely no sense. Just killing time here? No one said anything about racing the clock.
Squandered implies it was somehow a meaningful loss, at least that’s how I interpreted it.
It was meaningless time. If we’d gotten to our current development level ~5000 years ago, we’d just be writing these same comments next to calendars that had their zero sent to ~7000 years ago.

True, we (the ones reading and writing these comments) would likely never exist if the past was that radically different.
The oldest city that we’ve found to date was buried - intentionally - under a mound of earth.
There could be dozens of these sites

Flock will hire him as a consultant when they develop their upcoming "fine people for unpermitted garden sheds" service.
(joking, but sadly not joking)
Cities and counties have been using traditional aerial photography for that for a long time now.
I have friends who work in InsuranceTech and they use satellite images of houses when someone apply for home owners insurance. They've said it flags people with trampolines all the time.
My insurance company asked about that when I got the policy, I said Yes we have one and it was not an issue. Perhaps they are charging me a higher premium, but not enough that I noticed.
Though we no longer have it, so perhaps I should mention that next time I meet with my agent.
I was imagining what Indiana Jones would look like in this day and age.
Juvy record for the train thing, working as a waiter in the city the detention center was in.
It's going to get as common as
> New exoplanet discovered
Very soon.
And therefore unworthy of barely being mentioned.
I was going to say: that's a thesis result sorted - check.
Sighs and resets the 'Days since we discovered a lost city using LiDAR' counter back to zero.
How is this by accident? He was specifically looking for datasets for this purpose and found a good one, then loaded it into a program to find man-made structures.
Page 16 of google.
He might have been the first person to see those datasets except the ones who published them.
Ok, we've taken the accident out of the title above.
How many cities are lost every year? Can finding those cities help alleviate the housing crisis? Won't the inhabitants of those cities complain about disrupted postal service? I have so many questions!
Once again, the sensationalized "discovery" of a "lost" by people that fly over with lidar and never talk to the locals.

I appreciate the link but your comment isn't in keeping with the site guidelines, which include:
"Don't be snarky."
"Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something."
If you wouldn't mind reviewing https://news.ycombinator.com/newsguidelines.html and taking the intended spirit of the site more to heart, we'd be grateful.
Can the locals draw a map of these lost cities? Or are they just aware that there are many lost cities, but without knowing exactly where they are?
And for that matter, if the locals did know the specifics but weren't spreading that knowledge, then it still can constitute a discovery.
"Discovery" can mean revealing knowledge that was previously known to insiders, eg. if I say "I discovered an underground smuggling ring and reported it to the police", you probably wouldn't argue that "you didn't discover anything; the smugglers already knew about it".

Just wanted to say how much I'm enjoying this point.

Wow archaeology should be rife for disruption if you can just go around and ask locals. Seems like anyone with gumption could be the next great scientist.
Or maybe one of those locals could be. I wonder what stops them?
Locals lie.
Like a lot!
They even pretend to be able to read ancient languages/scripts when in reality that are just making stuff up.
This, but unironically.
> Or maybe one of those locals could be. I wonder what stops them?
They're living their lives, rarely becoming academics in the relevant field, assuming that local rock ruin is known to somebody outside of their community, or if not, then assuming nobody cares anyway.
You can probably find a lot of undocumented ancient stuff by asking shepherds in areas known to be territory of ancient poorly documented civilizations.
What is the proportion of villages where surveying the locals will lead to documenting an abandoned city that is otherwise only known to the locals?
If only 2% of villages have an undiscovered profitable heritage, then 98% of surveys will show no results, which makes it difficult for anthropological surveys to compete with lidar for grant funding, especially when lidar is still new enough to seem "sexy" and "sci-fi".
Throw in some AI processing of the LIDAR data, and watch those funding dollars flood in!!
To put into context how few funding dollars there are in archaeology, the NEH currently has $800k available for archaeological field research proposals. That's the largest "funding agency" pool for generic field research.
This same funding agency that doesn't directly fund computer research also has $2.5M available for proposals specifically targeted to starting collaborations researching AI alignment. They have another $3.5M for the actual collaborations themselves, and an additional $2.2M for AI work that "contributes to scholarly research in the humanities".
How about “discovered it for the world at large” I think there have been many cases where the locals knew about a lost city or even took stones for their farms from it for X purposes. Still it lets the government there know about a new lost city they can properly check out (or leave alone)
"Discovery" probably isn't the right word, but the important part isn't knowing that something is there, the important part is telling the rest of the world about it.
