Almost 50 million years ago, the biggest landslide in Earth's history occurred in Wyoming. An entire mountain slid 45 kilometers at one-third the speed of sound. But how could this happen when the slope was only 2 degrees?

Who ever is doing the thumbnail loves their job
I just assume everyone at SciShow loves their job.
Anyone know how to view the thumbnail after you've already started playing the video?
@DemPilafian click back. The video will mimimize and you'll see the RUclips thumbnail screen.
@@WeAllLaughDownHere-ne2ou Sadly, that does not seem to work on Macs. I tried both Safari and Firefox.
@@DemPilafian in chromium: ctrl+u, in the new source tab ctrl+f and search "lurl" (the last characters from thumnailUrl), you will see a link to the thumbnail next to it
If there was a vote for best mountain this one would win by a landslide.
*cups hands* booooooooooooo
omg 😂

Well played.
clicked on the video bc the thumbnail made me chuckle and then was blown away by geology. rocks are WILD
Missed the opportunity to say “rocks rock!”
@@dagenpracchia6683 From the pebbles on the beach to the cobbles in the street
Every stone that you can see will teach you rocks rock!
Want to move a mountain? Start a rumor that there's lots of gold in it. :>)
I love the idea of a levitating mountain. What an awesome world.
David Copperfield could do it.

I both work at Mt St Helens (largest *recorded* landslide in history) and have a love for geology, the weather, and physics. This is a topic I absolutely LOVE.
Out of any weather related event, landslide is the one that’s affected me most in my life living in SW Washington. Heavy rains often lead to landslides around here and shut down roads, school, and trains, even taking lives. Smaller ones have damaged vehicles (as opposed to just wiping them out)
Also, the Johnston Ridge Observatory is going to be closed for several years now because of a large landslide that came down along the highway. 300,000 cubic tons worth of ash and rock deposited by the landslide and subsequent eruption in 1980. I’d be curious if there was a layer of pumice embedded in the stratified deposits that got waterlogged during our record warm stretch of weather in May when this occurred.
I live pretty close to Heart Mountain. Didn't think I would see a SciShow video on something in my backyard
Well, I guess saying 'you can say to this mountain, "Move from here to there,' and it will move" has a new whole meaning
Just today I watched Myron Cooks Video on this Event. He explained it in a lot more detail and visited the key outcrops that helped geologists come up with this insane landslide theory. Big suggestion if you want to learn more about this event and also the landscape of Wyoming is quite beautiful.
It's called "Learn how supervolcanoes caused the world's largest landslide in Wyoming". It's indeed absolutely worthwhile watching!
I was just going to comment this, but I thought I'd look through the comments to see if someone already had. I'm so giddy that you've seen it. Myron Cook is a fantastic geologist and RUclipsr!!!! Definitely go watch all his videos!
do they just give the video title and maybe some stills to someone and go “make a thumbnail” bc it’s working
Forever known as that time a mountain said "screw you guys, I'm going home."
Aw, no curly hair today? The classic Hank is comfortable in its familiarity, but the curly hair makes me smile. It's a battle scar won from fighting one of humanity's greatest foes.
But you do you. You're lookin good, friend. :)
I'm thinking the video was recorded a long while ago (when the hair was just coming back) and only released now. He's got the curls in the ad read at the end!
@@EcceJack Very possible!
I think it's hilarious that I called this out the day before they released a video explaining why his hair is curly now.
2:35 , so the world's largest air hockey game?
You pick it up and then place it down.
Ahh ah ah! Not so fast, you have to take a few steps in between!
@@AnimeSunglasses Okay so.. Pick it up, take a few steps (about a few kilometers) and then, only then can I put it down?
@@neilangelomolleda7283 NOW you're talkin'!
I have been waiting for a video on Heart Mountain for years!!! This is a dream come true!!!
Myron Cook did one on it: "Learn how supervolcanoes caused the world's largest landslide in Wyoming".
The Noodle works in mysterious ways. Power of the Pasta.

Heart Mountian Slide sounds like a country song lol
I just watched the Myron Cook video about this.
The detail and complexity of the Heart Mountain Slide is astonishing. It's fascinating how many elements can work together in such an event. Really puts our Earth's enormous power and intricacy in perspective.
So you're telling me rocks made the first successful hoverboard millions of years ago? Raddddd 🤙🏼
Crazy I did independent study on this in college with my structural geology professor! Endlessly preparing thin sections of limestone and discussing what a deer might think as the mountain rolled across the landscape at incredible speeds
Genius thumbnail
"The biggest landslide ever discovered on land" 🙏
Landslides also happen in the ocean and cause tsunamis.
@@lenabreijer1311ah fair enough
Maybe it's actually the biggest landslide ever discovered in the sky. If a mountain is entirely surrounded by gas, contiguous with sky air, isn't it in the sky? The floating mountain of Wyoming.
The largest landslide documented so far is the underwater Agulhas slide which occurred off the coast of South Africa 2M years ago. The estimated moved volume was in the range of 20 thousands cubic kilometers. For comparison, the volume of Everest is circa 90 cubic kilometers. So, if the Heart mountain slide was about moving one mountain, the Agulhas slide was about moving hundreds of them.
Other massive slides happened in oceans. There is archeological evidence that massive landslides of the coast of Norway (estimated volumes 3500 km3) destroyed all humans settlements off the northern coasts of Europe 8000 years ago.
The thumbnail caught my attention! Plus, the video content is explained in such an accessible way, really easy to follow!
Oso landslide, Washington state, 2014.
Similar mechanism: thin layer of wet mud between rock layers acted like grease, allowing rapid slip.
Crazy thing is, people are starting to rebuild in the same spot.
Fascinating Hank. Geology Professor Myron Cook does an extended dive into Heart Mountian
big shoutout to the thumbnailer for giving me a chuckle on a dreary day
having already seen myron cooks videos on this has me very prepared
Same 😊 I was looking for someone else who saw it too
This video rocks
I love you thumbnail maker. You deserve a steak dinner and a good handshake
I first heard of this on geology hub and Myron cook's channels, it's incredible how such a slight slope could result in such a massive slide
Badgermoles what did it, I tell you
LEVITATING. MOUNTAIN.
Brilliant is brilliant
Now I'm gonna have that song stuck in my head...& randomly think about Hank's hair.
If you look north from Sheridan Avenue, Cody, WY you can see it very well. (There is Google street view all along it)
I remember thinking it looked really out of place compared to the horizon around it when I was young.
Shoutout Myron Cook.
"Shoutout Myron Cook." - one of his videos is linked in the description.
@@TheDanEdwards lmao you're right!
I literally just watched that specific video yesterday. 😂
Very cool.
Awesome. ❤
Thanks hank.
Liquified layer of clay can do this, especially with the help of a volcanic eruption. After a short while, it'll be carried by rubble and moraine.
I wonder if something similar was the case with the great non conformity at Red Rocks, Colorado?
If you haven’t done a video of the mystery of the different aged rocks at the amphitheater already it’d be awesome to see an explanation!
You’re telling me an entire _mountain_ isn’t rooted to the ground and is just a massive boulder sitting there? Wild
It's not quite a mountain, and not volcanic, but within my lifetime a huge part of Mam Tor - Derbyshire Peak District in the UK - sloughed off in a massive landslide. It is caused by unstable shale, the equivalent of the moving unstable particles in one of the explanations here.
Just a mustard seed's worth of faith can move a mountain.
The thumbnail caught my attention 🤗, it’s so cute☺️
"The man who moved a mountain...
... began by carrying away a small stone"
the florida peninsula was formed by the bottom bit of the Appalachia-Caledonia range falling into the sea. but geologists say that was a slow, erosion/deposition process, so i guess it's not super comparable
Hank 1 cancer 0 gotta love that
So in theory the mountain became the first ever hover craft in history. You got love nature when it throws a curve ball like this one.😹😹😹
So, somehow the friction got reduced. But what accelerated it to 1/3 of the speed of sound? It feels like a 2 degree slope would need extremely long to do that purely based on gravity.
From Myron Cook's video on the subject a number of the blocks from the heart mountain slide are emplaced on top of a pyroclastic layer with a number of line of evidence indicating a large voluminous explosive volcanic event happened either contemporaneously or in close succession with the landslide. If I had to guess these blocks were probably part of the uplift crypto dome of the large caldera complex before it ultimately gave way fairly similarly to Mt. St. Helens 1980 eruption only scaled up by over 3 orders of magnitudes.
If you have the time as they are a series of hour long 26 episodes in Nick Zentners A to Z Crazy Eocene livestream series from several years ago should provide some needed context as this occurred as part of the first phase of one of North Americas most dramatic tectonic and volcanic episodes the Tertiary Ignimbrite Flare up and the dramatic uplift rotation and extension which includes ripping chunks of the North American Craton off of the continent.
The exact cause of this is not understood but it's timing coincides with the collision between North America and Siletzia with what is now British Colombia and Northern Washington (but would have at the start of the even have been parts of rock strata in Washington Oregon and Idaho getting thrust hundreds of Kilometers north allowing a big portion of the huge active volcanic plateau/Large igneous Province that was Siletzia and Yakutat to get slotted in place. There ere a number of these large rotational translations as well as huge siliceous volcanic episodes which coincide in time with the uplift of large metamorphic core complexes by tens of kilometers vertically all happening within the span of a few million years starting with what are today parts spread out through British Colombia Washington Oregon Idaho and Wyoming though it progressed south over time eventually making up much of what is today crust spread out over Nevada Utah New Mexico Colorado. Incidentally the slide mentioned in Utah was likely also a part of this geologic interval as that matches with the timing of the exposure of relevant metamorphic core complexes and ignimbrite flare up episodes in the region.
My personal suspicion give the Crazy Eocene and subsequent Baja BC controversy series is that this episode likely was due to North America colliding with the East Pacific Rise and the major Large Igneous Province which had formed along it a contemporaneous sibling in the Pacific to Iceland linked to the Yellowstone hotspot. In this picture much of the movement would have been the unzipping of the Sevier/Laramide Orogenies which had formed as a consequence of North America colliding with a large mature microcontinental volcanic archipelago much like is in the early stages of ongoing between modern Indonesia + New Guinea and Australia.
In this view you would have had the Rocky Mountains form as a Himalayan style mountain range which subsequently got unzipped as the compression which had built it up was reversed into extension. Again most of what we know about such old events is limited to the rocks that survive so the mechanisms are unknown but whatever happened it was huge and tectonically driven
I grew up in the shadow of heart mountain
Will Scishow do news again? I miss that.
With your strongest most badass Kamehameha
Can we, people outside the US, know the area in units, please? Most of us do not have any idea how large Rhode Island is. 1:23.
Just googled Rhode Island and learned that there is a Rhode Island State and there is also a Rhode Island Island so I'm even more confused now.
-A long time fan.
Myron Cook has a comprehensive video which covers the heart mountain slide which looks at the rocks allowing you to get a real sense of scale.
This video misses out on the bigger picture. That chunk of rock is just one bit of a much, MUCH bigger landslide tens of miles away. Imagine rocks like Heart mountain sliding miles along with bigger chunks of rock. This video needs a video about the landslide :)
Reminds me of a song 'I can move Mountains'
Go Go Sci Show!
man thas craazy
Move thyn mountain, Hank!
wow the universe is so bizarre
came from tt, loved the meme
The USGS channel has a talk about this
Why do we think that the landslide went about a third of sound, also is this the speed of sound of air or the speed of sound in these rocks?
The speed of sound in a solid is extremely high, based on the estimate of traveling 48km in minutes they're talking about speed of sound in air. By contrast, traveling at 1/3 the speed of sound in *rock* for just two minutes would put you about 2/3rds of the way to the moon.
I was born in Powell in the shadow of heart mountain!!!!!
Imagine the fracking blowout from a decade? ago where that wall of sand came down the mountain & killed those two guys. Pressure sudden release.
I gotta wonder how it would feel to be on top of a mountain as it suddenly slides off itself
You would probably be dead in this case as from Myron Cooks video on the topic some of the other large mountain sized blocks which slid in the event(this was just one of the largest and furthest flung crustal blocks) preserve a layer of what appears to be pyroclastic material likely linked to an associated voluminous explosive eruption within the Tertiary Ignimbrite Flare up episode. It is speculation based on limited evidence but given the volcanics associated it was probably at or near a VEI 8 eruption perhaps something similar to Mt. St. Helens 1980 eruption only scaled up by over a 1000 times in terms of the amount of material involved.
Sadly much of the evidence on the extact specifics might be lost forever as the most recent super eruption of Yellowstone 640,000 years ago likely would have erupted through the material from the 50 million year older supervolcano that was responsible for the Heart mountain slide, as the epicenter where this crustal block came from is also within Yellowstone national park.
The same way Johnny Cash got his car.
Hail, Geology
I'm just imagining a skyscraper heading down the interstate.
Hi Hank!
The ad-read sounds a bit echoey.
Seem odd that the term “liquefaction” didn’t come up since that’s more-or-less what we are talking about here.
I remember a chinese story where an entire bloodline moving a mountain together, then blessed by the god
With faith.
Wondering at what speed you can change snow into steam for air hockey.
Weird ass thumbnail, cryptic ass title, oh yea this is gonna be a good one.
Ah, the pioneers used to ride these babies for miles
POPPA TOLD MOMMA, AND MOMMA TOLD NICK
YOU CAN MOVE A MOUNTAIN, IF YOU DO IT BRICK BY BRICKKKKKK
according to the Chinese, all it takes is a fool, determination, and generations inspired by the fool (愚公移山)
Almost like the 'punctuated equilibrium' theorized in biological evolution only with geology. Near stasis for centuries or longer, then all heck breaks loose.
Beed to bring them down, let clouds to the interior
never say "ever", its the biggest known so far! you are a scientist.
Maybe an angel turned it upside down.
If you have faith the size of a mustard seed
Darn, here I thought the answer was "teamwork"
how to move a mountain: you need a "сговорна дружина"
am i the only one thinking "what the heck... where are the curls?"
The video was just recorded a while ago I would assume
How to move a mountain? Slowly. Very slowly. Usually.
New "how they built the pyramids theory" still think it's aliens though.
Grind the stone, blend with ashes from burning rushes, and a little water.
The alkaline ashes dissolve the limestone, forming a paste.
This paste will firm up and become solid as it absorbs CO2 from the air.
Pack molds with the paste; this forms the blocks with the air-tight seams.
The blocks were cast in place, much like concrete.
2/3 of the workforce were growing rushes, burning them and gathering the ashes.
BTW, there's a Parrot in South America that rubs leaves onto stone cliffs.
The juices from the leave dissolve the stone, Parrot picks it out to make a nest.
Aliens aint got sh*t on Earth!
Look what a little faith can do.😂
"It's CO2"
Superman has left the chat.
Where did it come from?
Do a video on scientist making Quantum vortex in a jar first steps in a warp space highways
mountains are moving all the time. If they weren’t they’d appear to fly off into space.
Still trying to figure out where you're talking about. Montana?
It is in Wyoming though not that far away from Montana as the epicenter of what was the heart mountain slide and the ancient super volcano which caused it (See Myron Cook's video on this) was in Yellowstone national Park. I suspect the existing weak point in the ground is probably why the much younger Yellowstone hotspot fed supervolcano erupted where it did 640,000 years ago.
Cool. The next time I have to get yo momma out of the house, I'll know what to do.
hovercraft mountain
Paint it pink and set up a SEP field
Toph?!??
