I am predisposed to like videos about meteorite craters but this was even more interesting than I anticipated.
A nice example of a crater 2-3 km wide is Rotor Kamm in southern Africa. I should mention that we’re easily into city killer impacts here, in case you’re wondering.

From 1980 to the present, a timeline map of every earthquake in the world with a magnitude of 5 or above. You can play around with different parameters and data, so you can see where the different tectonic plates are, just see where the biggest earthquakes occurred, or add in volcanic eruptions. You can also draw a cross section and it will show how deep the quakes occurred along that line.
Artist and illustrator Andrew DeGraff makes maps that show where the characters travel during movies — imagine Billy’s trail maps from Family Circus but for films like Back to the Future, The Breakfast Club, Pulp Fiction, and Mad Max: Fury Road.
DeGraff collected these maps into a book called Cinemaps: An Atlas of 35 Great Movies.
Irving Finkel, a curator at the British Museum and an expert in cuneiform, takes a look at a 2900-year-old Mesopotamian tablet that contains a map of the world as it was known at the time.
The Babylonian map of the world is the oldest map of the world, in the world. Written and inscribed on clay in Mesopotamia around 2,900-years-ago, it is, like so many cuneiform tablets, incomplete. However, Irving Finkel and a particularly gifted student of his — Edith Horsley — managed to locate a missing piece of the map, slot it back into the cuneiform tablet, and from there set us all on journey through the somewhat mythical landscape of Mesopotamia to find the final resting place of the ark. And yes we mean that ark, as in Noah’s ark. Although in the earlier Mesopotamian version of the flood story, the ark is built by Ziusudra.
Finkel could not possibly look more like a British Museum curator than he does.
Btw, I first heard about the earliest Mesopotamian version of the flood story in a mythology class I took in college. I’d spent a lot of my youth going to church but religion didn’t click for me and I was never a believer. Hearing that flood story clinched it for me — the Old Testament of the Christian bible is just as mythological as the Greek or Mesopotamian gods (everything is a remix) — and I’ve been solidly atheist ever since.

This is kind of amazing: Calculating Empires is a project by Kate Crawford and Vladan Joler attempting to map how technology and human social structures have changed and evolved since 1500. This is just a tiny bit of the large genealogical map:
Calculating Empires is a large-scale research visualization exploring how technical and social structures co-evolved over five centuries. The aim is to view the contemporary period in a longer trajectory of ideas, devices, infrastructures, and systems of power. It traces technological patterns of colonialism, militarization, automation, and enclosure since 1500 to show how these forces still subjugate and how they might be unwound. By tracking these imperial pathways, Calculating Empires offers a means of seeing our technological present in a deeper historical context. And by investigating how past empires have calculated, we can see how they created the conditions of empire today.

Using LiDAR data from the US Geological Survey and a site called ReliefViz, a Reddit user created this lovely blue and greyscale shaded relief map of Manhattan (and the surrounding area). It’s worth clicking through to explore the full-size image.

I’ve always been a little fascinated by the list of the largest cities throughout history, so this animated version from Ollie Bye is right up my alley. While watching, it’s interesting to think about what makes cities grow large at specific times: a mixture of economics, demography, social movements, empire/colonialism, technology, and the like.
Always a good day to highlight the creative work of designer/illustrator Christoph Niemann: a collection of map-based work, including a cheeky metaphorical recipe for an omelet. That intersection isn’t actually that outlandish: see A Bonkers Highway Interchange and Crazy Whirlpool Traffic Interchange in Dubai.
When I linked to a recent NY Times article about rewilding golf courses, I pulled out this startling fact: “The United States has more golf courses than McDonald’s locations.” Nathan Yau of FlowingData found that that is indeed true but wondered where all of the golf courses were actually located. (A: typically not in cities where the McDonald’s are concentrated).
This makes more sense now. You can have a golf course in an area where there aren’t that many people, because people will travel to play golf. Few people are going to travel specifically for McDonald’s.
If we compare the two, you see the McDonald’s city concentrations, and golf fills the in-between spaces.
On Beautiful Public Data, Jon Keegan highlights the extremely information-rich flight maps produced by the Federal Aviation Administration that pilots use to find their way around the skies.
Among all of the visual information published by the U.S. government, there may be no product with a higher information density than the Federal Aviation Administration’s (FAA) aviation maps. Intended for pilots, the FAA publishes free detailed maps of the entire U.S. airspace, and detailed maps of airports and their surroundings and updates them frequently. The density of the critical information layered on these maps is staggering, and it is a miracle that pilots can easily decipher these maps’ at a glance.
Oh wow, this takes me back. My dad was a pilot when I was a kid and he had a bunch of FAA maps in the house, in his planes, and even on the walls of his office. I remember finding these maps both oddly beautiful and almost completely inscrutable. What a treat to be able to finally figure out how to read them, at least a little bit. And the waypoint names are fun too:
Orlando, FL has many Disney themed waypoints such as JAFAR, PIGLT, JAZMN, TTIGR, MINEE, HKUNA and MTATA. Flying into Orlando, your plane might use the SNFLD arrival path, taking you past NOOMN, FORYU, SNFLD, JRRYY and GTOUT.
Based on the waypoints near Atlanta’s Hartsfield-Jackson International, this airport must be home to some of the nerdiest air traffic controllers. There’s a crazy number of Lord of the Rings waypoints: HOBTT, SHYRE, FRDDO, BLLBO, BGGNS, NZGUL, RAETH, ORRKK, GOLLM, ROHUN, GONDR, GIMLY, STRDR, SMAWG and GNDLF.
Millions of years ago, the supercontinent of Pangea slowly started to break apart into the continents we all live on today. In this video from the makers of ArcGIS mapping software, you can watch as the reconfiguration of the Earth’s land happens over 200 million years.
Damn, India slammed into Asia like the Kool-aid Man — no wonder the Himalayas are so tall!
Once, the craggy limestone peaks that skim the sky of Everest were on the ocean floor. Scientists believe it all began to change about 200 million years ago — at around the time the Jurassic dinosaurs were beginning to emerge — when the supercontinent of Pangea cracked into pieces. The Indian continent eventually broke free, journeying north across the vast swathe of Tethys Ocean for 150 million years until it smacked into a fellow continent — the one we now know as Asia — around 45 million years ago.
The crushing force of one continent hitting another caused the plate beneath the Tethys Ocean, made of oceanic crust, to slide under the Eurasian plate. This created what is known as a subduction zone. Then the oceanic plate slipped deeper and deeper into the Earth’s mantle, scraping off folds limestone as it did so, until the Indian and Eurasian plates started compressing together. India began sliding under Asia, but because it’s made of tougher stuff than the oceanic plate it didn’t just descend. The surface started to buckle, pushing the crust and crumples of limestone upwards.
And so the Himalayan mountain range began to rise skyward. By around 15-17 million years ago, the summit of Everest had reached about 5,000m (16,404ft) and it continued to grow. The collision between the two continental plates is still happening today. India continues to creep north by 5cm (2in) a year, causing Everest to grow by about 4mm (0.16in) per year (although other parts of the Himalayas are rising at around 10mm per year [0.4in]).

The David Rumsey Map Collection is one of the true gems of the web: a massive trove of maps & related images from over 40 years of collecting.
Rumsey began building a collection of North and South American historical maps and related cartographic materials in 1980. Eventually the collection expanded to include historical maps of the entire world, from the 16th to the 21st centuries. His collection, with more than 200,000 maps, is one of the largest private map collections in the United States.
Italian filmmaker Andrea Gatopoulos has made a documentary film called A Stranger Quest about Rumsey’s passion for maps. Here’s the trailer:
And because I can’t resist, a few maps from the collection:
That last one is a screenshot of the results for “lighthouse” from their new Text-On-Maps search capability.

Growing up in northern Wisconsin, we said “tennis shoes” or “tennies” most of the time (even though very little actual tennis was being played) and “gym shoes” less often. I hadn’t really heard of “sneakers” as a kid and never used it. (Shoes for sneaking? Huh?) My kids were born in NYC and they give me shit every time I tell them to put their tennies on. 🤷♂️
What do you call athletic shoes? Tennies? Sneakers? Kicks? Trainers? Gym shoes? Some other weird thing? (via @dens)
Using survey data, responses from community boards & city council members, and over 37,000 responses from NYC residents, a team at the NY Times has made a detailed map of the 350+ distinct neighborhoods in NYC. From a companion article:
It’s a New York pastime to gripe that neighborhoods are invented and defined by real estate brokers, developers and other city gatekeepers. But the more interesting truth may be that they are also reinvented and reinforced, refracted through race and class, by us: by the air traffic controller who lives in Little Yemen, by the Manhattan community manager who’s sure his constituents live in East Harlem — and not “Upper Carnegie Hill” — and by the Brooklyn residents who decided to name a relatively flat piece of land Boerum Hill.
A name has power. It can foreshadow who will be moving in. By itself, it can conjure so much: gentrification, displacement, inequality, status. When we argue over names, or even invent new ones, we may be trying to exert some of that power — or lamenting that others have more power than we do.
We asked New Yorkers themselves to map their neighborhoods and to tell us what they call them. The result, while imperfect, is probably the most detailed map of the city’s neighborhoods ever compiled.
The article is interesting throughout:
Our map reveals two main kinds of divisions: sharp ones and fuzzy ones.
The fuzzy ones often reflect areas in transition or dispute, where there’s no consensus or where gentrification is rewriting boundaries in real time.
The sharp ones often reflect features of the landscape itself: wide avenues, highways, remnants of canals. When you cross the street, you know you’re in another neighborhood.
Next time I’m in NYC, I’m definitely going to Little Yemen for lunch.
I loved playing around with the National Audubon Society’s Bird Migration Explorer, which is a beautifully designed interactive map of the Western hemisphere that shows the seasonal migration patterns of more than 450 species of birds. What a resource…so much information to explore here. (via marco c. in the comments)
From illustrator Pablo Carlos Budassi, this is a circular map of the universe.
The solar system is located in the center. Towards the edges, the scale is progressively reduced to show in detail the most distant and biggest structures of the observable universe sphere.
There are several other representations of the universe on Budassi’s site, including links to prints, posters, and other products.
From XKCD, a 3D cutaway map of the many layers of the Earth, from the familiar crust around the outside to the more mysterious layers like nougat, vitreous humor, guacamole, and cork.
Well, it is that time of year again when the leaves in the northern hemisphere change colors. As usual, SmokyMountains.com has published their best guess as to when the leaves will be changing in various parts of the country. At the end of September and beginning of October here in Vermont, it’ll start looking like this.
Very Expensive Maps is, well, I can’t say it much plainer than host Evan Applegate: “Very Expensive Maps is a podcast by cartographer Evan Applegate in which he interviews better cartographers.” A podcast about a visual medium like maps is maybe a tiny bit like dancing about architecture, but Applegate makes it work. The archives are a key part of the show…lots of links to the maps discussed during each episode. Here’s a sampling of some of the visuals from recent shows:
This short video from Vox takes a look at the recent Supreme Court decision that struck down a gerrymandered congressional map in Alabama.
In 2013, a divided Supreme Court gutted one of the major pillars of the 1965 Voting Rights Act. In the 10 years since then, the court has moved even farther to the right. So when the Voting Rights Act came before the Supreme Court again in 2022, it didn’t look good for the law. But then something completely unexpected happened: in a 5-4 decision, two of the conservative justices voted with the 3 liberal justices to preserve the Voting Rights Act. And the effects could be huge.
At stake in the case was the way that Alabama divides up its Congressional districts. Alabama has seven districts, one of which is what’s called a “majority-minority district” in which Black Americans are the majority of the population. In 2022, a group of Black voters sued the state, saying that under the law, Alabama should actually have two majority-minority districts. And the Supreme Court agreed.
The decision could affect recently redrawn district maps in other states, which could in turn affect the balance of power in the House of Representatives. You can read more about these gerrymandering cases at the Brennan Center for Justice: Allen v. Milligan: Gerrymandering at the Supreme Court (Formerly Merrill v. Milligan) and Redistricting Litigation Roundup.
In this short video, Norwegian creative director Torger Jansen explains how he designed an unofficial transit map that combines all three of Oslo’s public transportation networks (tram, metro, train) into a single diagram. His four main goals:
1. Showing all the lines on every network, thus making it easier to understand the service patterns.
2. Making it recognisable with the official line colours.
3. Compressing unnaturally long distances between stations.
4. Balancing aesthetics and accessibility. The diagram is clear and easy to read with minimal fuss.
As Jansen notes, this is not how a design process would work in the real world — there’s no user testing or competing stakeholders to please — but from a purely aesthetic and functional standpoint, it’s still an interesting challenge and puzzle to attempt to solve. (thx, david)
For his project Study of Perspective, artist and activist Ai Weiwei took photos of himself flipping off “significant institutions, landmarks and monuments from around the world”, notably Tiananmen Square in 1995. Using this Google Street View-enabled web tool, you can use Ai’s middle finger to flip off anything you’d like, anywhere in the world.
I’ve included a few examples above from the site’s archive. In a brief review of what folks have done with the site recently, I observed several shots of the Kremlin, the Eiffel Tower, churches, and various Trump buildings, but I also saw the Stonewall Inn and other gay landmarks.
The USGS Astrogeology Science Center recently released a series of detailed geological maps of Mars that detail features from the red planet’s past like volcanos and flowing water. If you’re thinking, “hey that looks a lot like a river in that second image”, you’re not far off.
One particularly interesting feature that hints at Mars’ watery past is the sinuous ridge, which is a winding, narrow ridge that looks like an inverted river channel. These ridges are interpreted to be aqueous (formed by water), making them possible clues about the history of water on Mars.
The scale of the maps is useful for identifying geologic changes over time:
The new map of Aeolis Dorsa adds to the hypothesis that Mars was once wet and had abundant active river systems in the past before aqueous activity decreased over time. This change caused the primary depositional methods in the region to shift from rivers (fluvial) to sediment fans with intermittent deposition (alluvial) and eventually to a dry and wind-driven (aeolian) system. This local pattern mimics our current understanding of the global environmental history of Mars.
Lovely aesthetics as well. (via @geoffmanaugh)
After seeing an abstract US map where the borders between the states were preserved but the shapes of the individual states were not, Tom Comerford was inspired to design what he calls The Topologist’s Map of the World.
I describe this a a topologist’s map because topology is a branch of mathematics concerned with the way that space is connected. In topology it’s common to think of stretchy, distortable surfaces that can be moved around without being punctured or torn.
With many connections to other countries and bodies of water, countries like Russia, India, Brazil, and China are prominent on the map while the US, which only borders two other countries, is a tiny box in the corner. (via hacker news)
The first maps of the world were created without satellite imagery but with the compass, mathematics and geometry, reports from explorers, and a healthy dose of imagination & creativity. Jeremy Shuback briskly runs us through a history of early world maps, from perhaps the first map of the world by Anaximander (circa 610-546 BCE) to the Catalan Atlas, created in 1375.
The Catalan Atlas is worth a closer look — here’s a high-res image courtesy of Wikipedia and a 22-minute explainer/appreciation from Flash Point History.
In the early 2000s, Rick Meyerowitz and Maira Kalman made a version of the NYC subway map where names of all the stations and landmarks were replaced with food. Here’s a detailed view of lower Manhattan and part of Brooklyn:

The Tolkien Estate has built a new website dedicated to J.R.R. Tolkien and it includes dozens of hard-drawn maps, illustrations, paintings, and calligraphic works done by the author in the course of writing his books. Tolkien was a talented artist and his maps and visual art were an integral part of his work. From Artnet:
Tolkien’s art and writings went hand and hand, with illustrations serving as an an integral part of his creative process. Sometimes the words would inspire the artwork, and sometimes drawing a scene would move the narrative in new directions.
The author meticulously mapped out the world of Middle Earth to ensure the accurate movements of his large cast of characters.
I was lucky enough to see some of these maps and drawings in person at this 2019 exhibition at the Morgan Library — great stuff. (via @tedgioia)
From CGP Grey, here’s an explanation of the numbering system used by the US Interstate Highway System. Here’s the basic deal, from Wikipedia:
Primary Interstates are assigned one- or two-digit numbers, while shorter routes (such as spurs, loops, and short connecting roads) are assigned three-digit numbers where the last two digits match the parent route (thus, I-294 is a loop that connects at both ends to I-94, while I-787 is a short spur route attached to I-87). In the numbering scheme for the primary routes, east-west highways are assigned even numbers and north-south highways are assigned odd numbers. Odd route numbers increase from west to east, and even-numbered routes increase from south to north (to avoid confusion with the U.S. Highways, which increase from east to west and north to south).
In-car and on-phone GPS systems have made knowing this system largely irrelevant for most drivers. I spent a lot of time in the car as a kid — summer roadtrips around the country and frequent local travel out of our rural area — and loved maps & atlases even at that age, so this was pure nostalgia for me. The video covers some of the numbering exceptions at the end (like the 35E/35W split in the Twin Cities I used to drive on often), but I would easily have sat through 10 more minutes of them.
A Chinese man who was abducted from his family when he was four years old recently found his mother by drawing a map of his village from memory and posting it online. From The Guardian:
Thirty years ago, when Li Jingwei was four years old, a neighbour abducted him from his home village in China’s Yunnan province and sold him to a child trafficking ring.
Now he has been reunited with his mother after drawing a map of his home village from his memories of three decades ago and sharing it on a popular video-sharing app in the hope that someone might be able to identify it.
“I’m a child who’s looking for his home,” Li said in the video. Unable to recall the name of his village or his address, Li’s recollection and reconstruction of the village’s key features - including a school, a bamboo forest and a pond - proved crucial.
“I knew the trees, stones, cows and even which roads turn and where the water flows,” Li said in an interview with the Paper, a Chinese media outlet.
When I first read this story, I was interested in the incredible drawn-from-memory map but now I’m wondering about what kind of relationship Li has with the people who arranged to have him abducted (which the article calls his “adoptive parents”??!?) (via the morning news)
