Story about the Normandy landing. About 3 months before the landing, volunteers were taken to rowing distance from the beach by a submarine. The men were given black uniforms and had their faces blackened. Each was provided with an inflatable raft (black, of course) and a number of glass jars with lids and a black grease pencil. Each jar had a blank label attached. The volunteers' assignment was to row ashore, and collect samples of the sand on the beach, marking each with its location, then return to the submarine with the samples. The volunteers thought that the assignment was nuts, but they did as they were told. The carefully marked samples were later used to determine which locations would support the various vehicles to be landed without bogging them down.

I'm Canadian. Snow drifts are similar. So its interesting how similar it is despite being from different climates entirely. Even in cold icy wind the snow feels what i assume is similar to a sand storm when it stings you.
I've never realised how greatly these videos are made - its so cohesive, educational, understandable and informational while being very enjoyable and interesting!
I lived in Florence Oregon in the mid 80s and lived my teens in the dunes just outside my yard. Never knew Frank Herbert based the story Dune because of the dunes of coastal Oregon.
This is super interesting... ⚠️ I wouldn't have guessed they had them in Oregon but yet it makes sense... kind of. 🤔 When our boys where little & ambiguous we would take them outdoors away from the tv & we found a place just like this... only smaller... in Wyoming! Outside of Rock Springs. They LOVED IT! 😄👍🆓️
I used to live in WA, and the Oregon coast is the most magical place. The first time I saw it was actually at night, and after climbing over these huge dunes, I finally saw the ocean. The way it was so unobstructed east to west, coupled with the moonlight made it look like you could see the curvature of the earth. Definitely something everyone should experience!
Remember that sand moving creates a static charge that can last similar to a battery for weeks or sometime months. Like those "Sand Worms" with lightning around them. Pretty cool "Dune" included that fact.
@@sergiocoronel5402 Not really into the whole Angel numerology thing bubba or even "divine/supreme mathematics" theories but it is indeed interesting stuff I have to admit.
The real question is, after sand gets blown in a particular direction more than other directions, where does more sand come from? Or does dunes/ sandy deserts move overtime to other locations?
@@superpixelated7354 Sand is the final product of mining. They crush rock down to nothing the extract eevry ounce of the metals within it and the dump the sand into waste piles,
One of the cool things about Great Sand Dunes National Park is how the dunes are constrained to that area. There are two small creeks that run from the mountains to the north and east of the park, down around the sides of the dunes and peter out in a generally SW direction. The prevailing SW winds push the dunes in a NE direction until they encounter those creeks and then the sand is carried back down by the water around the sides to the SW and deposited there as the water disappears into the sand. Rinse.. repeat.
For those of us who live where it snows for 6 months every year, dunes are not that exciting, as we get snow drifts (small versions of sand dunes) every year. Some snow drifts even sing, maybe not as strongly as the dunes, but you can still hear it. 😀
@@AndrewBrownK Yes when conditions are just right. Also sometimes "rollers" form at the crest of drifts and descend the other side as hollow tubes about a foot or so in diameter. Google and you can see pics.
The Golden Gate Bridge also sings and the bridge in Oregon got into a frequency and bounced around until it was destroyed. I just saw a program where they think of making electricity from the vibrations in the wind and not just from turning a shaft. On two bit davinci.
@@timsteinkamp2245 The Tacoma Narrows bridge incident wasn't frequency like you're maybe thinking. It wasn't an audible noise like dunes or drifts make, it was just vibration, specifically at 0.2Hz. For reference, a super deep subwoofer bass is often strongest around 60Hz, and 20Hz is about the lowest humans can hear (although at that point it's more like feeling it than hearing it).
I think you can also see them in shallow waters below the surface in places where the currents are right too it doesn't need to be tidal per say even tsunami's can make such patterns with the right conditions.
13:32 "In that story the complex interplay of life and sand on the desert world Arrakis is threatened with collapse at the hand of humans." That's a rather interesting take on the theme of Dune. There is certainly a will from the Fremens to terraform Arrakis into a more hospitable place to live, a goal that is eventually reached after a few centuries, but it's never described as a "threat", and you make it sound like a side-effect of something else, like pollution, while it is a deliberate goal. The spice-farming itself has absolutely no impact in the ecological system of Dune. In the end Frank Herbert was tasked to find a way to "tame" dunes and deserts and his book is about that, not "respecting nature". It should also be noted that Arrakis wasn't originally a desert world, it was in fact a verdant planet like Earth and if there's a lifeform responsible for transforming it into a desert where almost nothing can survive it's the sandworms.
Just saw this video now and came to the comments right as he talked about the "theme" of Dune. I don't think he read it or maybe he didn't care and just wanted a way to put it in the script and thought he had to tie it to environmental justice lmao Unfortunately, Dune does not deal with much justice
“And to that I say: Knowing stuff is awesome”. Didn’t spect myself with sudden tears filling my eyes, thinking about my father and his endless journey for making me love science. Being here, learning about sand dunes, feeling kinda stupid, missing the now “old days” I suppose. Realizing that these videos, countless of the books in the shelf next to me, and what I call “useless wisdom”, has always been a hug, warm, naive and happy, like when I was in a museum with my dad. Its a cliche that I’m beginning to understand, everyday farther away from my childhood, makes sense what they say about science, “like a child again”. Grate video tho’. Thanks.
It’s incredible how you can find these beautiful patterns within nature, from the ripples caused by the oceans waves, to massive hills laid out in similar, yet vastly larger ripples. All you have to do is to look into the math of it all and you’ll gain a greater appreciation of the beauty of seemingly “simple” things like the dunes for example. I think one of the coolest examples of math in nature explaining a “system” that to us is supposedly chaotic or random, is the equation to calculate the “roughness” of costal lines. I can recall exactly what it was called, but it was found by the man who discovered the Mandelbrot set. This was at a time when we believed it to be possible to “create” a geometric shape not found to be already “created” within nature, there is a beautiful TedTalk by Benoit Mandelbrot on fractals and the art of roughness where he talks about all of this with more wisdom than I would be able to convey in this comment alone, so I suggest anyone interested in this topic, and with a bit of patience to really understand something somewhat complex, to check it out.
The final touch with William Blake's lines, beautiful! Yes, the sand dunes inspire you to think about something way bigger & larger, and they're very beautiful for that reason.
Another great video! Please make a video discussing how sand moves along the beach. Many beaches get wider and narrower seasonally. It’s intuitive that waves would wash sand away from the beach, but other times sand is being deposited by the waves. I can’t find anything about why some waves would deposit sand as the tide goes in and out.
There’s a dune where I live, in the coast of Spain (Duna de Bolonia), that’s swallowing a whole forest and killing it 😢. It’s a pretty popular tourist attraction though. People climb the dune, get back down and take all the sand off their bodies by bathing in the ocean in the beautiful beach of Bolonia.

The Silver Lake Sand Dunes in western lower Michigan are never mentioned in Dune stories. This is where I grew up. It was wonderful tumbling down the dunes & walking them for a day. The views of a blue Lake Michigan, blue sky, yellow sand and another but much smaller lake were magnificent even to a child. Sadly, now in my senior years many of the houses, trees, etc that were visible then, are covered over now. Even Silver Lake seems smaller. Yet the dunes still have their same shapes. Thank you for explaining why. Meanwhile the western winds keep coming across Lake Michigan.
great sand dunes is one of the most magical and amazing places ive ever been. its hard to understand how large a 700+ foot dune is until you're try to hike it
You just described Titan. The gravity is low but its atmospheric density at ground level is about four times that of Earth. (Atmospheric pressure at ground level is only 1.4 times that of Earth because of the low gravity.) So it would be interesting to know if the particles in Titan's dunes are larger than the ones on Earth.
There was a place in Northern California where I spent my teenage years called Ten Mile Beach. Sand dunes for miles. There were a few houses along the road that were in danger of being "eaten" with dunes towering 60-70 feet above them. There was an old skateboard with a pair of size 16 tennis shoes nailed to it. We'd go out there to party, and that board would always be there. it was great. You could go down a 100 foot sand slope at top speed wasted and if you wiped out not get hurt.
Love this! I had already planned to send this video to my son, because he loves to quote that line of Anakin's about hating sand because it's "coarse and rough and irritating and it gets everywhere", and then you mention Star Wars in the video! Bonus points! Maybe he'll see this comment too - Hi Mike! :)
This whole time I was thinking about the Space Balls scene where they’re on a desert planet. “Just a few more dunes to go” “You said that three dunes ago!” “Comb the desert!”
4:45 sections of our local beach can look like this at low tide, which reveals the interaction between sand and water. It's the same as the boundary between two liquids of signigicantly different densities, between air and water, water and sand, air and sand. As you said earlier, sand behaves as a liquid, although fluid would be a better term. Sand, air and water can all exhibit fluid dynamics.
i love your videos during the day and night. you are so interesting but i listen to your videos at night because of how calm your voice is😭 i literally fall asleep whilst your videos play in the background. sounds weird? probably but i don’t mean it like that nor in a bad way. love the videos!
I just camped on the Great Sand Dunes earlier this month! You can get a back country permit online. It was an incredible experience! The stars were amazing. It wasn't too cold. Sunrise was breathtaking. Do it if you have the chance!
The similarity between sand dunes and snowdrifts [and when snow was listed as sometimes being sand, too, that explained it!] has always fascinated me. Such beauty from chaos, just like was said in the video, is ... awesome to me. In the real sense of the word. I'm awed by the beauty _and_ the mathematics involved. But, on top of the sheer coolness involved, those humorous lines tossed in, like: "Call me Mr. Sandman." "...where he was played by Voldemort." and the like, PLUS the beautiful quote from _Auguries of Innocence,_ by William Blake, were like... the spices added to a beautiful and tasty dish, making it just - perfection! Thank you so much for this one! It was especially great, between the information and the excellent writing! More, more! _Author! Author! Author!_ _~standing ovation~_
Love this one! The Blake quote was just perfect at the end. For a bit there I thought you were at Monahans Sand Hills - obviously not a place quite as impressive in scale but pretty darn neat and a place I've actually been. I remember learning a tiny bit about the kinds of dunes there and the wind patterns. (also I remember rolling down several hills and having sand in my - um - everything) A fascinating particulate matter :D Also, good to know how to properly pronounce desertification, I've been saying it quite incorrectly and making the world turn into landscapes of sweets apparently.
0:13 No. actually... Why would that be confusing? i swear the things kids understanding at 8 years old, aren't even being taught until these kids are 17 now days.. the comprehension levels have diminished exponentially..
My brother and just went there for the first time last Saturday! Such a wild coincidence. I've been following you for a few years now, and this was just so cool!
Hey, about that, it'd be great if you could take a look at these two other questions: why these same ripple patterns that appear in the dunes can form at the bottom of the clouds? And, why, since erosion ends up taking huge amounts of clay, silt and sand into the oceans, the waters of the seas are not turbid? Oh, and, thanks for your videos. They're always awesome!
Well for one large bodies of water are very murky if you actually look at them. But also the clay and silts are heavier than water so it would eventually sink. So when it gets to the end of the estuary or reach the sea it's lost a lot of the kinetic energy and just gets pushed along the bottom without causing a disturbance higher in the water.
See Galveston water. It's not quite pollution (though that doesn't help), it's all the sediment from the Mississippi river that makes it all murky. If you drive a ship through there you can see all the sediment being kicked up in the water. As someone else mentioned, that sediment eventually gets moved to where it can settle and sink. There are sand banks that also get formed by delta deposition.
If I'm not wrong, that picture shows fractal defrosting patterns on Mars. Those "trees" are actually sublimation spots (small spots where the frost/ice has sublimated away, exposing the darker ground). We also see small fans, which form when jets of gaseous carbon dioxide erupt through a weak spot in the surface ice, ejecting dark surface material that then gets smeared across the surface by the wind.
They kinda do look like trees but they follow the topography of the dunes and sharply stop at their origin on the dune crest indicating avalached material. Perhaps concentrated hematite or damp soil from sublimation as suggested by Orbis Pictus
i'll make it easy , they are not going up , they are horizontal , that's just diferent color stuff "melting" away from dunes, like avalanches as we see them from above they look vertical , but they are actually like rivers flowing down
I grew up next to the St. Anthony Sand Dunes in Idaho. My tiny small home town was known for these dunes. They were great to sled on during the winter and bonfire on in the summer. The sand is SO soft and very light in color. I was always told that it formed due to something in relation to the continental divide? 🤔

The take home for me was when you talked about how large rocks erode, dust is lifted into the air, and sand is whats different in between. It should have been common sense physics and now it is. Great video.
Smart of you to upload a dunes video on the eve os the Dune movie US premiere. And thumbs up to the homage made. Walk without rythm, the spice must flow.
You missed one of the coolest things about wripple and dune movement, migration is not always in the direction of the wind. Dune and wripples can march both up and down wind depending on wind speed and angle of impact. Wripple marching upwind is so counter-intuitive but looks so cool!
Very enjoyable and informative video both in presentation and content. As someone who's lived primarily in a coastal area, I'd love to see a comparison how how the wind-driven sand compares to water-driven sand. Similar ripples are formed beneath the surface of moving water of coasts and rivers/streams. I find it very interesting. On desertification: I've always believed (possibly a naive belief) that desertification of the upper continent of Africa is what spawns the tropical storm and hurricanes that affect North America. Could we delve into how to "un-desertify" an area like the Sahara by the intentional planting of drought resistant grasses into those areas that may lead to stable areas for planting more permanent foliage to retain moisture and reverse the desertification process? Many coastal areas have taken such a position to reduce/eliminate wind erosion of shore lines by planting suitable grasses here in the U.S. Or do we just buy an electric car that charges from magical unicorn fairy dust (totally no carbon footprint in the production of electricity or batteries/storage) to solve the "man-made" climate crisis? Yes, yes, I'm one of "those guys" who asks pesky "why" questions and doesn't hesitate to point out inconvenient truths. Electricity requires a huge hydrocarbon input.... unless we're willing to re-approach nuclear power production conversations... you're still using fossil fuels in your electric car, possibly more than for an internal combustion engine running on dinosaur juice. I'm a blast at parties, or so I tell myself.
Amazing! I know that I have also seen sand ripples from underwater in the sea, and on beaches where the tides do their work. Water is also a fluid that which can move sand. It brings me to the following question: do underwater dunes exist on Earth? Maybe an interesting subject for a next video?
Idk why I always expect Joe to post every 4-5 days knowing that he has got a lot of things to do other than making videos. Maybe because I ran out of IOTBS videos.
I would love to see a video about why liquid flows down the side of a glass - I appreciate the brief mention here but it's still a mystery to me WHY that happens?!? Why doesn't gravity just take it straight down?
I'm willing to bet it has something to do with surface tension, the same reason a drop of water can stick to the bottom of a horizontal surface as long as it's small enough
hey just wanted to say that a volcano in "La Palma", an island on "Las Islas Canarias", an Spanish archipelago, is currently erupting. so if you're interested in that stuff you should give it a look
Followed Hawaii, Iceland and now La Palma in the Canarie Islands for years of amazing viewing. The comment sections on those natural events is both comedy and tragedy. Enjoy our planet, its cool but warming.
Have you noticed that stratos clouds behave the same way? I'd love to hear you talk about it, I suspect the mechanism is analog but more complex considering the material (ice cristals) are suspended in mid air. And always walk without rhythm 😁
We sand buggy riders can park in a line on the steep side of a tall dune then - on count - together coast and brake quickly... this can get a big slab of sand to start down hill singing... or we call it making thunder. Really a deep roar. I've only been able to do it on the Saint Anthony Dunes in Idaho. I've the wind blows well enough over night, we can do it again the next day.
With all the hype around the movie there’s no doubt this video will get more traction than average, u sir are a smart man and I’m sure whenever someone searches up dune they’ll see this video and might check it out
I'm from P.E.I. in Canada and here the Dunes ares federally protected and closely monitored. You absolutely cannot walk on them or touch the vegetation, some beaches where an endangered bird species lay eggs on the sand, you can't walk on or access either. Seeing you climb dunes instinctually makes me cringe. We have delicate ecosystems mixed with rare and endangered species of wildlife dependent on the dunes and cliffs. Climate change is having huge impacts on the Island, cliff dune erosion is a serious problem. It has even spurred new academic programs at local universities, focused entirely on climate change, and environmental protection.
I am a Geologist who loves physics and maths. I can hear you talk about sand, wind and everything in between for hours 😅😂❤ it's like a melody, a symphony soothing my heart lusty for rocks 😂 I'm Amazed and happy 😊❤ Dune movie reference was on point. I didn't knew that's how the book was written.
I live in the Palouse region of Washington and our rolling hills covered by grass were created the same way as sand dunes but are now one of the richest farming regions in the US.
Hi Joe. I read some time back about a 'soliton' dune where one sand dune in the Sahara appeared to blown through a ridge of dunes over the course of several months. It only got a short mention as the artical was about waves, a soliton being a larger than normal wave the persist for sometime. In the quantum world a soliton looks like a subatomic particle. This quantum concept is facinating but I've always wanted to know more about the soliton sand dune. Even after seeing the photos I find it hard to believe.
I think reading Dune at a formative age is why I don’t panic much in stressful situations. If I get really scared, my brain starts repeating “fear is the mind killer.” Stop, think, get control of yourself or end up dead. Thanks Frank!

The way it was so unobstructed east to west, coupled with the moonlight made it look like you could see the curvature of the earth. Definitely something everyone should experience!
@@elisabethandersen1102 you wouldn’t be able to see that because it’s flat but our eyes are interesting
Remember that sand moving creates a static charge that can last similar to a battery for weeks or sometime months. Like those "Sand Worms" with lightning around them. Pretty cool "Dune" included that fact.

Not like here, here everything is soft and smooth.
The real question is, after sand gets blown in a particular direction more than other directions, where does more sand come from? Or does dunes/ sandy deserts move overtime to other locations?
Dunes do migrate downwind, but new sand is also always being formed as rocks break down.
The wind that moves the sand also brings more sand and other materials
I feel like deserts are like landfills for sand which I don't know what factors attributed.
@@superpixelated7354 Sand is the final product of mining. They crush rock down to nothing the extract eevry ounce of the metals within it and the dump the sand into waste piles,
One of the cool things about Great Sand Dunes National Park is how the dunes are constrained to that area. There are two small creeks that run from the mountains to the north and east of the park, down around the sides of the dunes and peter out in a generally SW direction. The prevailing SW winds push the dunes in a NE direction until they encounter those creeks and then the sand is carried back down by the water around the sides to the SW and deposited there as the water disappears into the sand. Rinse.. repeat.
For those of us who live where it snows for 6 months every year, dunes are not that exciting, as we get snow drifts (small versions of sand dunes) every year. Some snow drifts even sing, maybe not as strongly as the dunes, but you can still hear it. 😀
I came here looking for the snow drifts comment. It still blows my mind how quickly they form.
Snow drifts sing?
@@AndrewBrownK Yes when conditions are just right. Also sometimes "rollers" form at the crest of drifts and descend the other side as hollow tubes about a foot or so in diameter. Google and you can see pics.
The Golden Gate Bridge also sings and the bridge in Oregon got into a frequency and bounced around until it was destroyed. I just saw a program where they think of making electricity from the vibrations in the wind and not just from turning a shaft. On two bit davinci.
@@timsteinkamp2245 The Tacoma Narrows bridge incident wasn't frequency like you're maybe thinking.
It wasn't an audible noise like dunes or drifts make, it was just vibration, specifically at 0.2Hz. For reference, a super deep subwoofer bass is often strongest around 60Hz, and 20Hz is about the lowest humans can hear (although at that point it's more like feeling it than hearing it).
Bc air is technically fluid. You’d see the same sand pattern near estuaries during low tides
I think you can also see them in shallow waters below the surface in places where the currents are right too it doesn't need to be tidal per say even tsunami's can make such patterns with the right conditions.
and in ABL clouds
Yep
Don't say technically

13:32 "In that story the complex interplay of life and sand on the desert world Arrakis is threatened with collapse at the hand of humans."
That's a rather interesting take on the theme of Dune. There is certainly a will from the Fremens to terraform Arrakis into a more hospitable place to live, a goal that is eventually reached after a few centuries, but it's never described as a "threat", and you make it sound like a side-effect of something else, like pollution, while it is a deliberate goal. The spice-farming itself has absolutely no impact in the ecological system of Dune.
In the end Frank Herbert was tasked to find a way to "tame" dunes and deserts and his book is about that, not "respecting nature".
It should also be noted that Arrakis wasn't originally a desert world, it was in fact a verdant planet like Earth and if there's a lifeform responsible for transforming it into a desert where almost nothing can survive it's the sandworms.
Just saw this video now and came to the comments right as he talked about the "theme" of Dune. I don't think he read it or maybe he didn't care and just wanted a way to put it in the script and thought he had to tie it to environmental justice lmao
Unfortunately, Dune does not deal with much justice
“And to that I say: Knowing stuff is awesome”. Didn’t spect myself with sudden tears filling my eyes, thinking about my father and his endless journey for making me love science. Being here, learning about sand dunes, feeling kinda stupid, missing the now “old days” I suppose. Realizing that these videos, countless of the books in the shelf next to me, and what I call “useless wisdom”, has always been a hug, warm, naive and happy, like when I was in a museum with my dad. Its a cliche that I’m beginning to understand, everyday farther away from my childhood, makes sense what they say about science, “like a child again”.
Grate video tho’. Thanks.
It’s incredible how you can find these beautiful patterns within nature, from the ripples caused by the oceans waves, to massive hills laid out in similar, yet vastly larger ripples. All you have to do is to look into the math of it all and you’ll gain a greater appreciation of the beauty of seemingly “simple” things like the dunes for example. I think one of the coolest examples of math in nature explaining a “system” that to us is supposedly chaotic or random, is the equation to calculate the “roughness” of costal lines. I can recall exactly what it was called, but it was found by the man who discovered the Mandelbrot set. This was at a time when we believed it to be possible to “create” a geometric shape not found to be already “created” within nature, there is a beautiful TedTalk by Benoit Mandelbrot on fractals and the art of roughness where he talks about all of this with more wisdom than I would be able to convey in this comment alone, so I suggest anyone interested in this topic, and with a bit of patience to really understand something somewhat complex, to check it out.
The final touch with William Blake's lines, beautiful! Yes, the sand dunes inspire you to think about something way bigger & larger, and they're very beautiful for that reason.
Absolutely true! Plus, I've always loved that Blake poem, anyway!

Another great video! Please make a video discussing how sand moves along the beach. Many beaches get wider and narrower seasonally. It’s intuitive that waves would wash sand away from the beach, but other times sand is being deposited by the waves. I can’t find anything about why some waves would deposit sand as the tide goes in and out.
There’s a dune where I live, in the coast of Spain (Duna de Bolonia), that’s swallowing a whole forest and killing it 😢. It’s a pretty popular tourist attraction though. People climb the dune, get back down and take all the sand off their bodies by bathing in the ocean in the beautiful beach of Bolonia.
Just visited great sand dunes National Park this year. If you're in Colorado it's a must see. Absolutely stunning
Why is everything "great" ?

@@calebm.mclaren8465 actually Mosca!
I think that's where he's at.
Is that the same mechanism for sand ripples in the sea bed, substituting water currents for atmospheric wind?
I would assume that the processes are the same... With the caveat that gasses flowing may not behave exactly like liquid . . .
and in huge sections of the american south west from the runoff of the great flood.
Basically yes. Waves move back and forth, whereas wind keeps going. So the patterns are a little different.

The Silver Lake Sand Dunes in western lower Michigan are never mentioned in Dune stories. This is where I grew up. It was wonderful tumbling down the dunes & walking them for a day. The views of a blue Lake Michigan, blue sky, yellow sand and another but much smaller lake were magnificent even to a child. Sadly, now in my senior years many of the houses, trees, etc that were visible then, are covered over now. Even Silver Lake seems smaller. Yet the dunes still have their same shapes. Thank you for explaining why. Meanwhile the western winds keep coming across Lake Michigan.
How far are these dunes from Kalamazoo?
@@dr.OgataSerizawa I'd say 2.5, maybe 3 hours north of Kzoo
great sand dunes is one of the most magical and amazing places ive ever been. its hard to understand how large a 700+ foot dune is until you're try to hike it
theoretically, on a planet with really low gravity, but really strong wind, could sand dunes be formed from pieces much bigger than sand?
You just described Titan. The gravity is low but its atmospheric density at ground level is about four times that of Earth. (Atmospheric pressure at ground level is only 1.4 times that of Earth because of the low gravity.) So it would be interesting to know if the particles in Titan's dunes are larger than the ones on Earth.
@@rais1953 cool! thanks for the thorough reply! :)))
There was a place in Northern California where I spent my teenage years called Ten Mile Beach. Sand dunes for miles. There were a few houses along the road that were in danger of being "eaten" with dunes towering 60-70 feet above them.
There was an old skateboard with a pair of size 16 tennis shoes nailed to it. We'd go out there to party, and that board would always be there. it was great. You could go down a 100 foot sand slope at top speed wasted and if you wiped out not get hurt.

This whole time I was thinking about the Space Balls scene where they’re on a desert planet. “Just a few more dunes to go” “You said that three dunes ago!” “Comb the desert!”
4:45 sections of our local beach can look like this at low tide, which reveals the interaction between sand and water. It's the same as the boundary between two liquids of signigicantly different densities, between air and water, water and sand, air and sand. As you said earlier, sand behaves as a liquid, although fluid would be a better term. Sand, air and water can all exhibit fluid dynamics.

"I don't like sand. It's coarse, and rough, and irritating, and it gets everywhere." Darth Vader
Bonus Greek God fact! In music, “Aeolian” is also the term for the minor scale
The similarity between sand dunes and snowdrifts [and when snow was listed as sometimes being sand, too, that explained it!] has always fascinated me. Such beauty from chaos, just like was said in the video, is ... awesome to me. In the real sense of the word. I'm awed by the beauty _and_ the mathematics involved.
But, on top of the sheer coolness involved, those humorous lines tossed in, like:
"Call me Mr. Sandman."
"...where he was played by Voldemort."

Here in Michigan, we've got tons of sand dunes. In the city of Hart, they're actually swallowing homes.
Love this one! The Blake quote was just perfect at the end.
For a bit there I thought you were at Monahans Sand Hills - obviously not a place quite as impressive in scale but pretty darn neat and a place I've actually been. I remember learning a tiny bit about the kinds of dunes there and the wind patterns. (also I remember rolling down several hills and having sand in my - um - everything)
A fascinating particulate matter :D

The sand looks so comfortable, uncomfortable, hot and cold all at the same time
My brother and just went there for the first time last Saturday! Such a wild coincidence. I've been following you for a few years now, and this was just so cool!
Hey, about that, it'd be great if you could take a look at these two other questions: why these same ripple patterns that appear in the dunes can form at the bottom of the clouds? And, why, since erosion ends up taking huge amounts of clay, silt and sand into the oceans, the waters of the seas are not turbid?
Oh, and, thanks for your videos. They're always awesome!
Well for one large bodies of water are very murky if you actually look at them. But also the clay and silts are heavier than water so it would eventually sink. So when it gets to the end of the estuary or reach the sea it's lost a lot of the kinetic energy and just gets pushed along the bottom without causing a disturbance higher in the water.
See Galveston water. It's not quite pollution (though that doesn't help), it's all the sediment from the Mississippi river that makes it all murky. If you drive a ship through there you can see all the sediment being kicked up in the water. As someone else mentioned, that sediment eventually gets moved to where it can settle and sink. There are sand banks that also get formed by delta deposition.
On this long awaited day of Dune's debut a vid about sand is what I want.
14:07 It looks like there are trees on Mars.
If I'm not wrong, that picture shows fractal defrosting patterns on Mars. Those "trees" are actually sublimation spots (small spots where the frost/ice has sublimated away, exposing the darker ground). We also see small fans, which form when jets of gaseous carbon dioxide erupt through a weak spot in the surface ice, ejecting dark surface material that then gets smeared across the surface by the wind.
They kinda do look like trees but they follow the topography of the dunes and sharply stop at their origin on the dune crest indicating avalached material. Perhaps concentrated hematite or damp soil from sublimation as suggested by Orbis Pictus
@@orbispictus6127 sounds good to me, I agree that they do kinda of look like trees though
@@orbispictus6127
I disagree.
i'll make it easy , they are not going up , they are horizontal , that's just diferent color stuff "melting" away from dunes, like avalanches as we see them from above they look vertical , but they are actually like rivers flowing down
I grew up next to the St. Anthony Sand Dunes in Idaho. My tiny small home town was known for these dunes. They were great to sled on during the winter and bonfire on in the summer. The sand is SO soft and very light in color. I was always told that it formed due to something in relation to the continental divide? 🤔

The take home for me was when you talked about how large rocks erode, dust is lifted into the air, and sand is whats different in between. It should have been common sense physics and now it is. Great video.
Smart of you to upload a dunes video on the eve os the Dune movie US premiere. And thumbs up to the homage made.
Walk without rythm, the spice must flow.
wow. what an interesting video. nice to stumble upon while reading the book!
You missed one of the coolest things about wripple and dune movement, migration is not always in the direction of the wind.
Dune and wripples can march both up and down wind depending on wind speed and angle of impact. Wripple marching upwind is so counter-intuitive but looks so cool!
Very enjoyable and informative video both in presentation and content.
As someone who's lived primarily in a coastal area, I'd love to see a comparison how how the wind-driven sand compares to water-driven sand. Similar ripples are formed beneath the surface of moving water of coasts and rivers/streams. I find it very interesting.
On desertification: I've always believed (possibly a naive belief) that desertification of the upper continent of Africa is what spawns the tropical storm and hurricanes that affect North America. Could we delve into how to "un-desertify" an area like the Sahara by the intentional planting of drought resistant grasses into those areas that may lead to stable areas for planting more permanent foliage to retain moisture and reverse the desertification process? Many coastal areas have taken such a position to reduce/eliminate wind erosion of shore lines by planting suitable grasses here in the U.S.
Or do we just buy an electric car that charges from magical unicorn fairy dust (totally no carbon footprint in the production of electricity or batteries/storage) to solve the "man-made" climate crisis?
Yes, yes, I'm one of "those guys" who asks pesky "why" questions and doesn't hesitate to point out inconvenient truths. Electricity requires a huge hydrocarbon input.... unless we're willing to re-approach nuclear power production conversations... you're still using fossil fuels in your electric car, possibly more than for an internal combustion engine running on dinosaur juice.
I'm a blast at parties, or so I tell myself.
Amazing! I know that I have also seen sand ripples from underwater in the sea, and on beaches where the tides do their work. Water is also a fluid that which can move sand.
It brings me to the following question: do underwater dunes exist on Earth? Maybe an interesting subject for a next video?
Not just in air, also those ripples with sand under water too.
Idk why I always expect Joe to post every 4-5 days knowing that he has got a lot of things to do other than making videos. Maybe because I ran out of IOTBS videos.
I would love to see a video about why liquid flows down the side of a glass - I appreciate the brief mention here but it's still a mystery to me WHY that happens?!? Why doesn't gravity just take it straight down?
I'm willing to bet it has something to do with surface tension, the same reason a drop of water can stick to the bottom of a horizontal surface as long as it's small enough

Great video for the first 12 minutes. Didn't care about the profound impact, just wanted to learn more about dunes.
We sand buggy riders can park in a line on the steep side of a tall dune then - on count - together coast and brake quickly... this can get a big slab of sand to start down hill singing... or we call it making thunder. Really a deep roar. I've only been able to do it on the Saint Anthony Dunes in Idaho. I've the wind blows well enough over night, we can do it again the next day.

I'm from P.E.I. in Canada and here the Dunes ares federally protected and closely monitored. You absolutely cannot walk on them or touch the vegetation, some beaches where an endangered bird species lay eggs on the sand, you can't walk on or access either. Seeing you climb dunes instinctually makes me cringe.
We have delicate ecosystems mixed with rare and endangered species of wildlife dependent on the dunes and cliffs. Climate change is having huge impacts on the Island, cliff dune erosion is a serious problem. It has even spurred new academic programs at local universities, focused entirely on climate change, and environmental protection.

Hi Joe. I read some time back about a 'soliton' dune where one sand dune in the Sahara appeared to blown through a ridge of dunes over the course of several months. It only got a short mention as the artical was about waves, a soliton being a larger than normal wave the persist for sometime. In the quantum world a soliton looks like a subatomic particle. This quantum concept is facinating but I've always wanted to know more about the soliton sand dune. Even after seeing the photos I find it hard to believe.
I'm so glad that I kept watching, I'm listening to the audiobook version of Dune right now!
