I once read a theory that said that the Richat actually used to be the city of Atlantis, because it has about the same dimensions as how Plato described it, and if you use the maps of Herodotus and Eratosthenes, the location as Plato described it makes sense as well. According to those two maps, there used to be a sea where the Sahara is now. But then again, earth pimple makes sense too. It's just less fun.

what is the lethal dose of scishow?

Mauritania's Eye of the Sahara is so beautiful, i saw a 3D documentary about places and they included it and it was amazing, in the future i will visit it, hopefully

So you're saying... it's an earth pimple.

This is Atlantis

Geolocation: 21°07'22.5"N 11°24'01.5"W So you can set your GPS and go there! :D

I'am mauritanian, and i really feel ashamed because i didn't visit this amazing structure

I really enjoy when you do episodes revolving around geology. It would be awesome to see more of them! Maybe something on gemstone formation, or how geological features can alter regional climate, or cool geological features that result from tectonic movement or concepts like what goes into mountain building or the mechanisms behind plate tectonics, etc.

no educated person would leave out the uncanny resemblance to Atlantis particularly since its measurements are almost identical to Plato's description including freshwater in the center (a well was dug to check and there was fresh water), mountains to the north, rivers in the mountains, etc

This is more the stuff I like to see on sci-show. A lot of the stuff lately has been less interesting.

I have been to Guelb Richat and it is a huge structure and the small plants are totally different to the region. It was an amazing visit!!

*Bright Insight and Mysterious Middle East, bought me back here.

we need more geologic subjects! this is great

This is Atlantis. Bright Insight

You haven't done one of these videos in a long time. Glad to see this one come up.

I love that I actually know what he's talking about- we've recently learned about things such as the "asthenosphere" or more in depth about M, I, and S rocks.

This is VERY cool! I wish you would make a much longer video just about this.

next episode of weird places you should try to decode walmart.

We love scishow Hank! And it seems you all love doing it! Thanks scishow team!

How the hell have I NEVER heard of that before?!

The details of this structure fit Plato's description of Atlantis very very well. I'm not saying it is, but there are quite a few similarities if one looks into into it.

How come the episodes have gotten so small? I miss 5-10min episodes

Crazy what nature can do. Beautiful.

I really love the weird places episodes! Do more!

that was so cool. how did i not know about this?!

more weird places vids please :)

Thanks for the speculation!

"Keep a big ol' eye out for it." Best. Pun. Ever.

It's the lost City of Atlantis. The same size, the same shape, the same description of the mountain in the north. The ancient map of Herodotus also confirms it.

Its atlantis

Weird Places is my favorite series on this channel.

I learnt something new today, thanks Hank.

Hank, how did you resist comparing the geologic dome to a pimple?

i missed this series

I was literally just trying to understand this half an hour ago, my textbook was confusing me - so thank you so much!

Love your videos!

I bet you there's some sort of alien conspiracy about this.

Discuss The Loudness War, please!

That so beautiful!

We have very similar structures in the WA state Lake Missoula flood plain. They are carved into the basalt flows. They were created by giant whirlpools. In a world flood scenario, whirlpools this large would not be terribly far-fetched.

You cant hide it anymore, we all know its Atlantis.

Here's a question. Why does weather affect mood?

you should do weird places videos more often

Long day Hank? Could we see some more of these? I always love hearing about weird/crazy stuff on Earth; people talking about mountains and valleys and exciting driving roads is so mundane.

That's where the Forerunners burried the artifact that opens a slipspace portal to the Ark! (Halo fans will get it)

You almost discovered Atlantis 😂😂

That was wicked cool!

This is really easy to find with Google maps or google earth. When I first came across it I was sure it was a crater, but the anticline explanation explains more things.

My statement may seem absurd to some, but I think this really is the location of Atlantis. Using Plato's description of Atlantis in his book "Critias" - Critias states that Atlantis sank underwater after a massive earthquake and flood 9,000 years prior to him. Doubt it's an exact figure, but - This seems to reference the Biblical "Great Flood" (melting of the ice glaciers) that occured about 12,000 years ago. Northern Africa must have looked very different about 12,500 thousands of years ago or before the glaciers melted. Given the many dried out channels found all around the Eye of Sahara region, chances are the rivers flowed through the city. and maybe the city even had access to the Atlantic ocean. This would explain all the sand. The thousands of miles stretches of sand can only be created by the flow of ocean water. However, after the flood - Northern Africa sank below the ocean. When it came back up from the ocean, all that was left was an empty, desolate desert with a weird circle that scientists today claim is a collapsed dome created by volcanic activity which I just don't buy and which they're not even really sure about. I've never in my life seen a circle in nature that perfectly matches Plato's description of Atlantis. I've never even seen a so called "collapsed dome" in nature. Not one picture that I can find online so I say BS. I'm sticking to my story this is probably Atlantis. I can't prove it, but the evidence is stacked. The location, surrounding geography, the shape, approximate size. And their story of a flood some 12,000 years ago matches scientific consensus that a massive flood occurred around then following the glacial meltdown. It's either Atlantis or the landing site for a 40km wide flying saucer. There's no other possible explanation. Okay maybe there is, but I like to fantasize.

Due to it's size and uncanny symmetry it was hard to fault scientists for thinking it was a crater, formed from some massive impact. But actually it was aliens.

yes more of these

More of the Weird Places Series!

100 million years! That's a long time-just saying

Nice shirt/background combo

i like these segments

I love you’re voices and videos

Really interesting. Never even heard about it, but it looks awesome. One question though: What's at the center of it? A city? A monument of some sort like a sign that says, "center of the eye," or just an empty expanse?

Anyone come here after randomly discovering this on google maps?

Hello SciShow. My name is Miguel. Your show is fun and educational which usually isn't something one can get on the inter-web computer at the same time. I would love to see an episode on stellar mega structure. like the Dyson's sphere, Alderson's disk and the like. Practical applications estimated cost and just fun science speculation.

Low orbit is one thing, but seeing it personally on the hand... that would be more interesting and awesome.

Actually it formed from the alien spaceship that dropped off the primordial goo that we evolved when it took off.

It's Atlantis!!!!!!!!!

A cartoon of how such a thing forms would help. But thanks 🙏 for pointing this thang out! 👍

That is toats fascinating!

There's nothing volcanic about that formation. That's Atlantis.

This looks like an ancient eroded mining site similar in size shape etc to those working mines today.

Imagine seeing that in person!

love knowing this stuff, always interesting to learn. and yet while i'll remember this for years, i wont be able to remember shit for my exams in a few weeks.... greeeat

Its a sign from Helix!

I've never noticed that before!

So cool. I'd like to visit that.

SciShow should do an episode about Trompes and isothermal compression.

So basically an anticline is an earth pimple

Am I the only one who initially read "Marijuhana's Eye of the Sharia" ?

PSyCHoHaMSTeRza was the first to come to the theory of it being Atlantis and that was 4 years ago. All others followed him. He deserves all the credit.

More Weird Places Please!!!!

What I love is all these scientists tell us exactly what it is yet none of them have ever set foot there or studied it. Lol they are all full of s#%*. They are all just talking out of their asses. Perfect circles, ESPECIALLY concentric ones, do not happen in nature other than in liquids. The other thing this host didn’t talk about is that the TOPS of the rings are all perfectly flat and level, as those the tops were cut off and perfectly leveled flat. It is very odd since all of the other hills outside of the richat are uneven and rounded.

How do tattoos work?

Looks like an imprint from a really large space craft, the geographic location would be an ideal place for a terraforming project..

Please do more weird places episodes!!!

actually is aliens

OR, or....hear me out..................ATLANTIS

Nice and beautiful

That's so freaking cool..

Wait.... 6 views and 7 likes.... WHAT

Yay! Anticlines! Geology is one of the least popular sciences, so I'm always happy when it's talked about and taught.

What a visually visually stunning future! Good thing we got to spend most of the video staring at the hyperactive host instead.

Who would've thought atlantis was in the world's last country to abolish Slavery?

You guys should do a video on the alien city located in Hale Crater on Mars. The ESA website has some great images of this area. Check out you-tube for some interesting videos on this subject. I would love see you guys try and explain this.

This isn't a serious answer but aliens, its always aliens.

I am really digging your new hairstyle!!! Like because of new hair ;)

very neat and if you look at it on google maps and go up and to the left you can see something that looks just as amaing

I have a question, how come certain people can't wear watches without them running out within a week? I did not believe this until my mom showed it to me (she got a new watch and it ran out within a week). When I googled around I found that this is not rare and a lot of people have this happen, I just can't find a good explanation that does not disagree with something another site said; one site said something about psychic vampires O_O... so I can't find a *credible* source.

Wow those teachers really got in your head 😂 this is Atlantis man 🤦🏻‍♂️

It's been awhile since you guys did a "Weird Places" on SciShow.

I have been there! It doesn't look as spectacular when you are down there because it's so huge.

morytania :o jk

I found it on Google Earth :D

By its position and size and shape make it a really compelly place for Alantice. Even acording to horoditus...

There needs to be a video done on the possibility of this being Atlantis
