I think the reason they thought California was an island initially was bc of they saw the Peninsula of Southern California and guessed the rest of California looked the same way.

[@franzo.one.franzo]

this is the actual reason

[@General.Knowledge]

I agree!

[@kugsyy]

The peninsula is called baja I think

[@GumSkyloard]

That makes all sense!

[@baraxor]

It seems that the earliest maps of the area, from the latter half of the sixteen century and apparently based on Spanish reports, did correctly show Baja California as a peninsula of the North American continent. However, when relations with Spain deteriorated through the reign of Felipe II and sources dried up (what little navigation in the Pacific being limited to the annual Manila Galleon, and the Spanish Royal Government wanting to keep potential rivals out of its "Lake"), mapmakers in France began to show California as an island, and mapmakers elsewhere followed suit, so that maps from France and the Netherlands throughout the seventeenth century depicted the "Island of California" without any foundation. Terra Australis was invented because geographers could not believe that the land masses north of the equator were not matched by a vast continent south of it.

[@samuele7098]

European maps had been impressively accurate long before the advent of satellites. Obviously they weren't as correct about the lands they were exploring at the moment of drawing a map, but starting from the late 15th century they did an impressive job considering their very limited tools, and by the 18th century their renditions of Europe, norhern Africa and the middle east were almost perfect.

A popular one was also the north american inland sea. People believed you could take a boat upriver on the east coast, and you'd end up at this inland sea, which could also connect to the pacific. It's also how New York came to be. The Dutch were looking for a specific river that supposedly connected to this inland sea. Hudson found this river and followed it till it became too shallow. The entire area was then claimed by the Dutch, which leed to the founding of new -Amsterdam, later New York.

I mean, they were right to believe in a great inland sea connecting to the Ocean. The Great Lakes connect to the Atlantic via the St. Lawrence river - You can literally sail to Minnesota. The only part they got wrong was thinking there was a pacific connection.

Hi! I think I read somewhere that the reason they thought there was a Terra Australis was because they felt that there had to be a similar amount of landmass in the southern hemisphere to "balance" the landmass they knew was in the northern hemisphere! Also, please can I recommend that you read a book called "The Phantom Atlas" by Edward Brooke-Hitching - fascinating read, beautifully illustrated and expands upon this fascinating subject :-)

[@paintingdreams290]

yes that is true, however, when first discovered Australia was presumed to be a island for some reason the British claimed it as a continent.

[@gerardbryant4840]

The idea of an inland sea in Australia came about because early European explorers discovered several rivers running roughly to the Northwest, on the western side of the Great Dividing Range. These all run into the Darling River, which runs Southwest, and joins the Murray river. Lake Eyre is a large inland body of water, but is isn't permanent.

[@albertbatfinder5240]

Nope, there’s not enough precipitation, even allowing for the fact that an inland sea with attendant vegetation might create more precipitation. The “problem” is that there’s no mountain range like the Rockies or the Andes. A high mountain range to the west might lift moist prevailing winds up high and generate a suitable climate. As it is, all the rivers of Australia combined don’t discharge as much water in a year as a river like the Amazon, the Congo or the Mississippi discharge in a week.

Talking about scale, one French king remarked that he'd lost more land because of his cartographers than he'd ever lost through war. I've read that Chinese compasses pointed south, not north, so maybe their maps were orientated to have south at the top? I've no idea what their compass needles pointed to, unless they just followed the south end of a needle that was actually pointing north.

[@General.Knowledge]

The first part sounds really interesting, I wonder what other consequences there were because of faulty maps

[@natanfevrier2367]

Our geographical south is the magnetic north. The needle of a compass turns towards the southpole and we put the north on the opposite side to know the geographic north. Antarctica probably contains the "magnetic rock" that is talked about. Or so I have been told in school...

[@Compucles]

@@natanfevrier2367 No, compass needles do in fact point north for the most part. It's just that the "magnetic rock" is actually a group of mountains containing a lot of iron ore in Northern Canada.

[@xenotypos]

@@General.Knowledge Actually, that king made that remark after he saw what was the first totally accurate map of France (and probably of Europe to this degree), so it's the previous maps that were wrong. The name of that map is the Cassini map, some youtuber did a video about it if I'm not wrong. When cartographers have to use their "imagination", they tend to give more room to the place they live than there is really. So when an objective precise map is created, that place is general smaller than in the fantasy maps that preceded.

The story of the Island of California is a bit more complex than that. When the Spanish first discovered Baja California, they did indeed think it was an island. But with in a few years, it was quickly determined that it wasn't (you know, by not being able to sail north without hitting land). So, for years, it was, correctly, depicted as a peninsula on maps. Then an explorer at the northern end of the Gulf of California saw some lagoons where the Colorado River flows into the head of the bay, and started spreading rumors that he thought they might be actually the start of a full-fledged straight (presumably to get himself more exploration commissions). So - despite the fact that people had been recorded *walking* to Baja California around the northern edge of the Gulf of California, cartographers suddenly took this one explorer at his word and started portraying California as an island again. This took about a century to fix, when the King of Spain literally sent more people to walk on dry land to California to prove to everyone that it was attached to the mainland.

[@jemleye]

If you ever do a part two, Scandinavian region is a very interesting example of this: 1. Older maps had Greenland as another extended peninsula of Northern Europe connecting to northern Norway. 2. The mythical island of Thule kept being mapped and referenced quite often in medieval and renaissance maps in the Norwegian Sea: upload.wikimedia.org/wikipedia/commons/b/bf/M%C3%BCnsters_skandinaviakart_%2824957076285%29.jpg 3. The number of peninsulas in the Scandinavian region took a lot of time to settle into what it actually is, going from one peninsula of Norway and Sweden with modern Finland on a vague eastern continental side, to having up to three: Scandinavian peninsula, Finland and the mythical land bridge to Greenland. 4. A bit more niche, but Europe's largest lakes of Ladoga, Onega and the White sea were placed initially a bit all over the place, within the Finnish peninsula mostly, and with the White Sea often represented as a lake.

I know in early maps of Tasmania that Macquarie Harbour was often vastly overscale compared to the rest of the island and this appeared in a few maps of the time. The west coast of Tassie was inhospitable and wild for most of colonial history and repelled many surveyors from discovering what lied within. Lake Pedder was also one of these features that saw some repeated errors, namely that the rivers that flowed in and out (before it was impounded in a modern reservoir) were often shown to flow backwards, draining into the Huon. I generally assume that this was because it seemed that the mountains formed a wall to the west that was clearly the source, when in reality, the Serpentine River actually punched through the mountains via a gorge and drained west to the Gordon. Also on Tasmanian west coast cartography issues, the southernmost extent of Macquarie Harbour, a little arm known as 'Birchs Inlet' seems to have not been accurately mapped until modern aviation in the 40's. In reality, it's shape is long and heads in a straight line south, but early surveys of Macquarie Harbour that only peered through it's mouth, misread it as having a swollen, curved shape. This weird error went on unnoticed for a century or so to the point that the latest I've found a map to still show it like this was the 1950's. At that point, aerial surveys were widely referenced and the old misunderstanding was erased for good.

[@breysendettwiller5690]

I have heard a statement (I think by Map Men?) that may explain the weird island in Mexico. A lot of cartographers used to add some small false pieces of information as a sort of watermark to indicate that someone else stole their work if it was put into another map. It could be that someone did this and maps just kept using that same piece of information for years. It could be something else as well though.

A good comparison for these mistakes is how we are currently mapping out the universe and the errors and issues we come across as we do. Most pictures of planets that we see are simply art and imagination, and only until recently did we have a picture of a blackhole. Other aspects of these maps purposes, only hinted on in this video, is propaganda. California was an island full of only women, a laughable notion today, but something that may have gotten a few more sailors on to boats, or at least accept their fate. I suspect the river and sea in Australia was a similar attempt, as no colonizer is going to sail that far to live on a huge desert. Rich fertile land was the goal back then, and they only needed you to believe it long enough until the boat set sail.

I've read the passage about the California island. It was vaguely described with no hard location or size given. So my theory is that it was describing one of the Channel Islands off the coast of Los Angeles. But the explorers, going by the description, would have mistaken the Baja Peninsula for an island if they passed the San Francisco Bay without going in. "This must be that island those guys were talking about... Either that or it was one of those ones that we passed a few days ago... We'll have to leave it to next year's expedition. We have to get back around The Horn before the weather turns too bad." Being the first European Explorers in the area, they may not have had a deadline, but they were expected to return as quickly as possible. So they didn't have time to dawdle and make things perfect. The next round of explorers, having a good starting point, would clarify things. Combine this with the behavior and competitiveness of Cartography at the time, and you have a mishmash of maps of varying degrees of accuracy. Believe it or not, after the next two or three missions, the California Island maps became less and less common because of the clarification of the later exploratory missions. In fact, those maps were already uncommon by the time Ferdinand the VI made his declaration, and most sailors knew the truth; considering the island maps inaccurate before the declaration was made.

[@VanillaMacaron551]

Maybe not inland seas, but at least two massive inland irrigation schemes with huge dams have been developed in northern Australia - one around the Burdekin River in north Queensland, and the other is the Ord River Scheme in the north of Western Australia. However a much better known map mistake was that Tasmania was joined to the mainland - many maps were produced showing this. The fact that it is an island was only confirmed by Europeans in the very late 1700s when Matthew Flinders circumnavigated Australia. Also, just noting your graphic had a pic of Arizona-style cactuses to represent Australia's desert regions. We don't have those!

Oddly enough the idea of California being disconnected from the mainland is something I went with in a sci-fi story, set in the far future that I'm slowly writing. After a 6 miles wide asteroid impacted in 2535, N.America was cracked in half and a massive new fault line appeared. Starting in Washington and cutting across the Yellowstone caldera turning down into Kansas and down through Texas. Resulting in high sheer cliffs as the eastern half dropped and the western half rose. This created cliffs from 300 to 1000 feet in height. Another change was that the San Andreas finally did split and the Pacific waters flowed into the gap. This separated the western half of California into a chain of islands I called Pacifica. I even created a map of N.America to show how it may have looked after meager remnants of humanity re-emerged from underground shelters sand caves after about 230 years and began to rebuild.

So flooding that with sea water would kill most of the wildlife there and not make much of a difference to the climate. So probably not a good idea. Flooding the Qattara depression in the Sahara looks more promising, and has indeed been proposed several times (including using nuclear bombs to dig the canal). Still wouldn't make much difference for the Sahara as a whole but might add some habitable land to Egypt (or maybe not). Digging a hole big enough for a whole artificial sea in the middle of a desert is of course completely beyond our current technical abilities.

@@peterholzer4481 the ancient civilations would be able to, but not us.. look at mines.. we can but if no ressources to keep money income. I bring those who certainly are just our ancestors here because look at angkor vat, I mean just look at everything else like the pyramids or machu pichu they must have way more strenght and dedication, and of course much more logic, intelligence, like something that were way above our understanding of matter, physics and all this, like they could control matter, like shaping matter something that primitive people like us would call magic.. yes we are the primitive..

@@jeanbarque9918 I think you vastly underestimate how much easier modern technology makes large scale projects. The Hoover dam has about the same mass as the great pyramid of Giza and is a much more complex construction, but it was completed in just 5 years with a few thousand workers. And that was 90 years ago ... We could easily build a Machu Picchu or Ankor Vat today. There just isn't much incentive to do it. I don't know if the ancient Egyptians would have been able to dig a canal to Qattara at all - it might have filled up faster than they were able to dig it. Today we could certainly do it - the question is whether it would be profitable and politically feasible.

“Another mistake was ‘Bermeja’. Located in South America…” The irony here is General Knowledge VO guy made the mistake of identifying Mexico as being located in South America and not in North America. One would think the channel would do its due diligence in doing proper research. Then again the channel is known as “General” Knowledge and not “Accurate” Knowledge, so that tells you something….

He also shows a map of the USA when he talks about California being off the coast of North America, instead of a map of New Spain or North America. Then he asks "if California were an island would it STILL be part of the USA?" As if he's unaware that the peninsula is the original California.

Literally no one lives in the parts of Australia shown to be the inland sea, they should create it in real life to drastically expand the habitable land

If viable, it would be very cool yeah!

can't blame em for making mistakes

[@caos1925]

one reason they thoguht there must be a massive southern continent, was to 'balance' the world, thinking the south and north hemispheres must have about the same amount of land or the earth would be unbalanced. Astronomy wasn't too good yet either...

3:18 given that the coastline is relatively accurate, wouldn't the fact that there is no giant delta where it says it should be be an evident proof that that wishful thinking was misguided from the start? 7:33 because they thought that without a big southern landmass the Earth would tilt.

i’m even suprised that they managed to do anything good by hands….

Bermeja was not located in South America but in the Gulf of Mexico, which is North America

[@Lim0n41k]

It's not "for whatever reason" it's about Earth axis being a certain degree. It's been figured out that in order for it to be that exact degree there *must* be another landmass in the south so that's why people was looking for it
