I saw them in 1976. I assumed either the wind was pushing them on very slick sediment that got wet. Or, they were frozen in shallow water ice floes and floated, pushed by wind. I worked at the Nevada Test Site and the dry lake sediment I had to deal with was slick as snot when wet. And I had seen ice move on the frozen dry lake beds. Never put together the gooey silt PLUS the ice. WAY COOL.

But they explained at the end, it doesn't require a slick base like gooey silt... the wind pushing on that large sheet of ice produces forces stronger than bulldozers that would move the rocks even in a high friction environment.

Millions of people on this planet know things that, to them, are just basic, unremarkable parts of how the world works. "It's not worth telling anyone about. Doesn't every know that?" And at the exact same time, there are people poring over problems, looking for data, trying to find connections in all the wrong places....that would _immediately_ be solved if they knew other folks had seen that problem play out in nature/at their job/in the real world. But that's just not how it works. Too many people. Too much world. People are small and their experiences and connections are limited. The times that such things _do_ happen and people come forward with data or proof that makes a previously unsolvable paradox completely mundane are pretty famous, and for good reason. It just doesn't happen much. Or, well, it didn't use to. Nowadays it happens a lot more often, cause people post questions online and then some dude from the middle of nowhere goes "Huh. I know a place that happens all the time" And research happens.

Living in the land of ice near the northern part of the Great Lakes we witness a number of unique ice events. Including wind driving the spring ice amazing distances with perceptible speed along with great force. Separately a Friend of ours has a rock quarry that upon occasion seems to let some large rocks travel as much as a hundred yards without any apparent provocation. Always in the cold season and a bit slower than walking speed. These rocks, sometimes the size of a VW, are usually relatively flat bottomed and move while the ground is frozen with no visible pitch to the ground. One of these rocks weighed close to 50 tons(we know because we were unable to lift it with a 50-ton crane). lce and gravity, amazing stuff.

[@tswdev]

I remember hearing about rocks being moved by icy winds on salt water dry lakes because the wind would hit one side of the rock, freeze the water on that edge, the ice would expand and lift the rock, then more ice would get under it and eventually it would be enough to lift the rock and move it a tiny tiny bit. Then the ice would melt and the rock would have moved and no one knew why

At 6:13 in the video, several papers are shown. John Reid, the first author of Sliding Rocks of Death Valley: What makes them move? was my advisor at the time (1995); the other authors were fellow students. I was not part of the research team, but as a student at a collaboratively oriented college , I did participate in discussions and making the calculations presented in the manuscript. To my knowledge, it was the first time large scale detailed measurements were made and the required wind shear forces were calculated and resolved with the mechanism of wind shear on a large ice sheets and reduced friction of the rocks on wet mud , and the conclusions were fundamentally correct. Notable in that publication is mapping that demonstrates that rocks moved in groups that would divide into subgroups, an observation that necessitates either ice sheets or divine intervention to accomplish! The contribution of the research by the Richard and James Norris is to irrefutably demonstrate the findings of that research with technology not readily available 25 years ago. It is important to give all credit where credit is due. The contribution of the Norris' work is wonderful, and it satisfying to see the phenomenon that we understood 25 years ago so elegantly proven. I think it would be more accurate although perhaps less sensational to say that they provided the unequivocal proof of research that solved the mystery in 1995. Congratulations to all!

[@DamGreek]

I've made many trips to Death Valley over the years, and my favorite place is definitely the Racetrack Playa. It's fantastic to see the "mystery of the rocks" solved in this video. I always felt that it had something to do with the playa becoming wet and slippery, but "ice" never occurred to me. I will also say, to anyone who'd like to make the trip, yes, it's long way, and lots of driving, but it's well worth the effort and somewhat life changing. There's an energy that stays with you, when you see the rocks with their long tracks and also see the Grandstand in the distance. One tip, which I learned to help prevent getting your tires punctured on the gravel roads in and around the area, is to take out about 15-20% of the air in your tires. This will soften the tires, and will allow them to flex a bit more when driving over jagged rocks. This flexing, will prevent the rock from puncturing the tire tread. And once back to Stove Pipe or Furnace Creek, you can refill the tires with air, or carry cans of air, which are easily bought at a car parts store. Works great, and I have never had a flat!

[@nobodyknows3180]

the presence of water in the soil, the weight of the rock forming a compressive load on the soil, water could be squeezed out and form a thin film. Much like when ball bearings get lubricated with oil - at operating pressure the oil forms a thin film between the bearing and the race - no actual metal-on-metal contact. Or when an ice skater whizzes across the ice, the narrow skate blades concentrating the weight of the skater into a small area, and this amount of compression liquifies the ice, so the skater is literally hydroplaning at all times.

Just before Easter in 1986, I watched a light breeze push the winter ice off Lake Wallenpaupack in Pennsylvania. I walked on to the ice that had reached dry ground and rode it as it slowly pushed ashore, piled up and broke into flimsy shards and ice straws. The ice pushed a huge nearby boulder through the sand and mud, leaving a trench about eight feet wide and three feet deep. I could reach into that rotten ice and crush it so easily in my hand, but the massive force exerted by a light breeze on the surface of a couple of square miles of ice was absolutely unstoppable and awesome to see.

Please - if you want to visit the playa, don't walk on the surface if it's at all soft - your footprints will ruin it for everyone else that comes after you for decades. Kudos to them for solving the mystery, but every time I see something else published about this place, I know it means it will never be the same again...

Honestly, given the place floods and receives precipitation and forms ice sheets, you can't ruin it unless you're actually digging. It's an environment in flux and even some footprint wear will be eradicated and resurfaced relatively quickly. Decades seems like a massive stretch.

[@StephenPruitt]

@@DaveDexterMusic Respectfully, you might want to do some more reading about the site and the process. Any given rock with a trail moves, on average, every seven to ten years. Rock trails often have more than one event, and so likely go back ten, twenty, or more years. The site floods very infrequently, and the surface is so hard, water (it's not much - it's hard to call it flooding) doesn't "resurface" the site - it doesn't erase trails or footprints. A set of footprints, depending on where they are on the playa, could easily be there for thirty or forty years, or longer, only disappearing very slowly. There are signs at the site asking people not to walk on the wet playa for these reasons.

Something similar occurs all over fields in New England. This is the reason for all the low rock walls that litter old farmland there. Farmers had to get them out of the way, off the fields, because otherwise they would move! I read an old pamphlet from the late 1800s where the author calculated there was more stones built into New England walls than in all the Egyptian Pyramids. Not just to mark boundaries, but because otherwise the rocks moved along the fields in winter, especially when temperatures hovered just around the freezing point. The big difference is that no New Englander ever thought to publish such findings in a scientific paper. Seen as a big mystery to be solved by 21st century academics in the California desert, just seemed too ordinary to make a fuss about in ye olde New England.Because otherwise the rocks moved along the fields in winter.

Get well soon Dianna! Can't wait to see you back 👍

Fantastic! But why 8 years later is this just making "the rounds"??? I swear I've seen people more recently claim that this was still an unanswered mystery while standing in the middle of the playa. Did they just walk by the sign and ignore it so they could perpetuate the mystery?

The explanation didn't involve extraterrestrial visitors, so it wouldn't have fit the narrative. :)

Internet hysteresis... I guess the mystery gets more clicks than the answer (would be different if the answer was, say, aliens...)

A few years back there was an article about natural phenomenons, all done in nice photography, and the sailing stones were discussed as being solved with a short explanation about the ice formation. This video finally gives an in-depth explanation.

My family used to vacation in the amazing death valley in the winter...! Saw the amazing "race track" several times in the early 1970's, before the actual reason was found. Awesome place full of cool canyons, Scotties castle, mines, salt flats, craters cool places, great views, awesome military jets blasting through the canyon.

There are also volcanoes, or more specifically monogenic volcanic fields which feature a single eruption from a vent and then never erupt again, often many thousands of years apart. (effectively they are volcanoes that weren't able to establish a stable conduit to the surface Still even if you don't get to see the event there are the left over basaltic lava flows and mar explosion craters

"Dianna! I love your presentation of this extremely interesting event. Your enthusiasm is infectious for people of all ages from children to seniors like myself. I noticed that up close the ground in Death Valley reminds me of the shell of an armadillo. And that map showed the word dessert 😂 instead of desert. I spend a lot of time on my mobile and P.C. because of chronic Vertigo and I had to leave a career in Cardiology because of it. So I spend my time as a Chronic Encourager helping other people find healthy and entertaining subjects to enjoy. It was a pleasure to watch your show, I will be sharing it with others and mentioning the Counseling Service.

Reported this video for plagiarism. Here is a video from 7 years ago explaining the phenomenon kzbin.info/www/bejne/bmqQcnl-nsp3pq8 It's not good to pretend you are the FIRST to discover something. If you want conducts new experiments to re-confirm or disprove a confirmed fact that's fine. But you should make it clear in the beginning of your video you are NOT the first person making the discovery.

@Mortgage Approvals You are such a buzz kill. You enjoyed killing this girls excitement, which you don't find on the site you recommend. She was showing the story from her point of view of the same things. It's like hearing a song more than once or watching the news on different channels. That is until you felt the need to show off that you've seen this before. It was a different point of view with a genuine interest. Climb back in your hole. No one will notice or care. I am certain all the people who watch KZbin only a very few saw the video you are touting. Again, your negativity is not appreciated. If you wanna fight, there are real wars in this world. Go get involved in one and leave innocent people alone. Dianne, thank you for bringing your joy & enthusiasm to this subject & mystery to some. Thank you for seeking out the men who discovered this and telling their story. Without your video, many would not know.

Great vid! I didn't know this was solved! One of my professors at Cal State Fullerton told us about this years ago and it always fascinated me.

I mean.. NO. I don't buy this!!! Water flows in ALL directions.. The rocks would be all over the place. The overview picture proves it's some kind of magnet or force underground!!!! They all move in symmetry. Check it out. This is not solved.. Not in my view. . have they even been digging? tell me that someone! How deep did they dig?

I manage a cemetery in Idaho, during an average winter with average freezing temps and minimal rain fall we often get headstones weighing well over 200lbs that will twist, shift and sometimes entirely fall off of their bases. Mother nature is awesome.

As being a SoCal kid, those bumpy roads are easy..You just get to a certain speed, so you stay on top and it's smooth sailing from there!!! As long as you stay on the road that is hahahaha

[@PrometheanConsulting]

Re: the Spain phenomenon - When I lived in Houston, we'd get flash flooding from storms that drifted in from the gulf. The hard rain would lift petroleum out of the roads and it would be an instant oil slick. And shortly after the rain, due to the heat of the roads, they water would evaporate almost instantly. The ice mechanism might not be the only one but neither might the salinity of the soil be a factor either. And for that matter, fresh water could be freezing (dew, hail) and the salinity might melt the lower layers only for the top layer to refreeze.

[@geometricart7851]

I think you answered your own question as to why the rocks move in spain. "the petroleum"

Hello Physics Girl from Wales. I've just found your channel and about to explore the great subjects that you cover. Many congratulations on some excellent content. On the subject of ice sheets and wind moving things i have actually seen this happening. Please search for Caerphilly Castle and you'll see that it has a moat. The moat freezes with layers of thin ice regularly. Mainly because it is where the coldest air accumulates at the lowest point in a geographical basin and freezing flowing air down from the Welsh valleys etc. When younger it was customary to find shopping trolleys thrown into the moat. Over time the trolleys would migrate across the moat because the mass of the ice could simply drag them. When walking home from school we might see them in a different place each day.

I love your Geology videos. I am a geologic engineer and did undergrad at university nearby. We camped there many times in winter to try to catch the rocks moving on the racetrack. It should be noted that the playa clays are VERY slippery when wet, reducing the coefficient of friction very much when water gets involved. We visited in winter (pre GPS device days) as we favored the ice hypothesis, glad to see more observations to support it. Some of the most windy nights I have experienced were there, the winds are definitely very powerful
