Where do the Dumont dunes come from? I camp out there every year for Thanksgiving with my family it’s only 6 mi.² I can ride around the entire thing in less than an hour but I can’t really figure out why those dunes are where they are
Are you sure that is a desert? A desert is defined by dryness. I believe there are dunes, even singing ones, but dunes can build itself outside of deserts too.
The only true desert in Canada (excluding the Canadian Arctic) is Okanagan Desert in British Columbia. You’re most likely thinking of a badlands or shrubland. Sand dunes are possible but sand + space ≠ desert. Rather it is defined by how much precipitation an environment gets less then 250mm of rain each year. Hence why Antarctica is a desert as well.
Fascinating episode. To me, the sand dunes have a grace and beauty that is undeniable. Increased areas of desertification, however, are of real concern. Perhaps Arrakis is our future.
I've been hiking Eureka and Kelso Dunes for decades and have noticed this phenomenon. There was an article in Scientific American maybe 25-30 years ago, and I remember writing the author offering to collect sand samples on my next trip. He said yes, please send a cubic yard. Uh, I don't think either of us thought about how much that weighed or how hard it would be to send that, but I did my best.
The recent flash flood we had in the desert not far from Death Valley deposited a sand dune right next to my master bedroom wall, I hope it starts singing LOL😆. It did teach me, that not only wind moves sand Dunes, desert flash flooding moves them very quickly! And although it is beautiful, I'd love to keep it, I'll need to use an excavator to move it. Having it so close to the house means that it likes to migrate its way into the house. 😕
This is so amazing!! I'd love to hear this in person and slide down one of those dunes... even though it looks really dangerous and aren't they gonna get a bunch of sand in all their cracks and crevices scooting around like that?!?!
@@mimischiffman626 Oh awesome! Were you one of the folks in the video? If so, would love to know how long it took to climb those dunes and what the temperature was like!
@@elijahclaude3413 I was! I filmed some of the tight (non drone) shots in the US parts and produced and edited this video! It was hard climbing the dunes! You lose a lot of traction as you climb! Super good workout honestly. The temperature was manageable when we were climbing. We shot early to avoid the heat.
@@mimischiffman626 That's so incredible!! Thanks for this awesome and for taking the time to reply in the comments. Super lucky that you get to do things like this!

There are singing sands on a number of beaches. When you walk on these beaches, the sound reverberates and makes a sound. The beaches are really not so dry...they are beaches, after all.
It's undoubtedly a resonace pheonomenon generated by some tuibulance due to a wind excitation and must be a self-excited sound forming a resonace due to the geometric shape of the sand dune. The point to study is how the sand and air motions act as a positive feedback force to the natural sound instrument.
I live near a beach where the sand squeaks when you walk a certain way....funnily enough it's called Singing Beach. One of only a few beaches in the world with that characteristic. I believe it has to do with the dryness of the sand and what the particles are made of.
I have been to the Eureka Sand Dunes in the northern part of Death Valley National Park in the mid 1990s and heard the singing sand noises VERY clearly and loud. I returned more than 25 later in late April 2021 could just barely create the sounds, he few times I did it only lasted for a second or two. Pretty sure the sand just wasn't dry enough.
Okay... so this seems like it really should have been said explicitly: If you're just standing there at the base of a set of dunes that can sing, and there's nobody ON the dunes moving things around, can they sing? Or do you need people to be on the dunes scooting, moving the sand, for the singing (booming) to happen? Or does either way work, but scooting is the only way for a person to CAUSE it to happen when it isn't naturally happening?
Sand avalanches occur on their own when the conditions are right. The wind will cause them to occur periodically. If they aren't happening naturally and you want to hear the booming while you're at the dunes you can initiate the avalanche. That's what we did with Dr. Hunt and her students!
a diagram/animation/chart or something visual aid regarding the dune structure and what's happening to generate the sound would have made this better. thanks.
Those five people slowly making their way down the dune also changed the shape of the dune. Sand is not a granite mountain. And, as stated, the sand at the top of the dune is the lightest and easiest sand to move. So find the “influential” dunes and manage them.
How wise it it to be out in 118F going up a giant hill? Was that just the hottest time of the day and the people climbed the hill when the temp was better?
Yep sand and wind can make weird things. Question can we do a video on farms and how much water they wast and how much co2 it makes even without animals. Why farms use so many chemicals and fertilizers that co2 just gets dumped out into the atmosphere and the runoff is killing all wild life birds fish soil life and its killing water quality and reducing o2 in water.
Hallo..I'm windi oktavia from shandhika widya cinema the keajaiban dunia program Net TV. Want to ask for this account video and permission to play the net TV kejaiaban dunia program, and then we'll include a source/credit title with this account name, thank you
The complexity theory of consciousness could possibly explain it... in which any system that is sufficiently 'complex' (like lots of sand grains) becomes 'conscious' (even if it's rudimentary like basic harmonic tones.. the tones could be an expression of a primordial basic awareness once the conditions are right)... After all silica is the basis of information processing as we know it in computers. 👾❄️🥳 It would also jive well with the mineral and Crystal 'origin of life' camp... In which life itself came from rocks and crystals...

Please don't play the marimba while asking us to listen to the dunes.
How do you know it wasn't the dunes, eh? Maybe they needed some melody to sing to.
I wish there was a moment of silence so we could hear the singing dunes
Like the one at the very start of the video?
@@AustinSteingrube That marimba sound comes from the dunes? Cool! And 3 seconds doesn’t count
Yes!
background music can be very irritating
That must have been a pain in the ass to scoot down that dune in shorts! Your voice pulls me out of my mind wanderings, thanks Joe
Literally!
Why add background music to something you specifically want us to listen to. Poor editing guys
I was looking for this comment 😂
They stopped the music when playing the sound
@@SureTadpoleYT yes but pretty far into the video
@@JusNoBS420
I’ll agree
Plot twist: the music was actually just the dunes
It's kind of annoying that's you're playing music while trying to show what the dunes sound like. Not really necessary.
Beautiful narration. I’m happy to see the passion and determination these scientists have for all things on Earth.

Fascinating Science investigating the Singing Sands . We have a desert in Quebec where I've heard singing sands a few times

@@brianisme6498 BC would be my last guess for a desert but I love learning stuff lol. Thx for the info
It's course, rough, irritating, and it gets everywhere.
But music from the dunes makes up for it!

That was a really quite remarkable turn when upon sliding down the dune face, a sound started it's boom. Whoa!

It’s pretty forgiving if you fall. And the sand did get everywhere but shook out pretty easily :)

Maybe this can make Anakin Skywalker like sand again
Can we get this again without background music smothering the sound of the dunes maybe please and thank you?
It sounds more like a steel drum rather than a cello to me.
Wow, 8:40 is just beautiful!
*That’s WILD‼️ Love This, Thanks.*

These dunes, they sound like....
BEEEEEEEEEEEEES! BEEEEEEEEEEEEEEEEEESS!!
ARAAAAAUGH! 😱
so much potential for band names. Dune Boom, Marching Dunes, The Singing Sands..
I live near a beach where the sand squeaks when you walk a certain way....funnily enough it's called Singing Beach. One of only a few beaches in the world with that characteristic. I believe it has to do with the dryness of the sand and what the particles are made of.

Having come here straight from It's Okay to Be Smart, this was doubly interesting :D
I watched a video of scientists sliding down dunes to activate the singing...
_"That's not the sound of the drone you're hearing,"_
It's the ornithopter!
Okay... so this seems like it really should have been said explicitly: If you're just standing there at the base of a set of dunes that can sing, and there's nobody ON the dunes moving things around, can they sing?

Honey? Why do you have sands in your underwear?
Eh... Science!
Science? Sure...
This was very interesting.
what a beautiful desert~!
Reminds me of the 'drum sands' in dune
Well, that's ruddy mysterious.
I was trying to listen to the singing dunes but there was MUSIC PLAYING OVER IT. Guys.
I hope we can hear it in dune part 2
That is awesome
a diagram/animation/chart or something visual aid regarding the dune structure and what's happening to generate the sound would have made this better. thanks.
It is not the heat that makes the desert dry. It is the low relative humidity in the air.
Patiently waits for a producer to sample them.
Wow!! The dunes play a marimba too?!!!
Thanks! 🌀❤️🌀
How cool would it sound to Sandboard down it?
Those five people slowly making their way down the dune also changed the shape of the dune. Sand is not a granite mountain. And, as stated, the sand at the top of the dune is the lightest and easiest sand to move. So find the “influential” dunes and manage them.

Maybe just Sand Worm singing 😁
I dont know which Joe is my favorite Joe
Great science
nice video again
I saw on TV,awhile back,that there is a fish that lives in the sand. is that really true? can't remember where it was but it was deep in the sand.
Of course this is coming out with the new movie coming out
I’ve heard the Kelso dunes but not Dumont
If you look closely you can see rich spice beds at the base of these dunes
Now I'm wondering if the same physics explanation would work for the ripples seen on a large lake on a super windy day...?
Wouldn't this also explains shadow deserts? How deserts are always on the other side of large mountain chains.
I think it's because the mountains block the clouds and prevent rain. Without rain, the sand and other debris from the mountain cannot be washed away
Yep sand and wind can make weird things.
Question can we do a video on farms and how much water they wast and how much co2 it makes even without animals.
Why farms use so many chemicals and fertilizers that co2 just gets dumped out into the atmosphere and the runoff is killing all wild life birds fish soil life and its killing water quality and reducing o2 in water.
You are forgetting South Africa and Australia, as well as the desert southwest in the US.
could you add non white references to the videos, like what the people in chile thought about the dunes.
Seems like if you're doing a video about singing sand dunes, you could dispense with the stupid background music, for once.
Does sand eventually become dust? If it was originally pebbles, they would need to be eroded by water.
Y'all really tried to ride the Dune: Part One SEO wave didn't ya?
And then we force out grad students to fill their shorts with sand. For science!
Why you’ll never go hungry in the desert….Because of all the ‘Sand-which-is-there’. 🥯 🥪
So, it works like orbital resonance in Saturn's sandy rings
can glaciers sing like sand dunes? after all, both have avalanches.
I prefer dessertification 🍰 😋 🤤

Can anyone just play the sound without any other noise for a good 10 seconds? I'd love to hear it, but every video is clouded with noise.
if we divert dunes to avoid populations of humans.. wont they likely be diverted into animal habitats? we all connected
what singing dunes? i only hear you talking over it
