- If you take a look at a map of Scotland, you'll notice an eerily straight line running through the highlands, this is the Great Glen Fault the product of half a billion years of time and geology.

Greetings from the US. I'm a New Englander and it's definitely my sister's fault.
This shows that Scottish independence is inevitable in the next 66 million years
😂😂😂
Sooner if I can help and it could be my fault again!
Only for the northern Highlands
@Bamsebrakar2011 it's fine we'll apply gorilla glue to the fault between lowlands and the highland so it can come with
😂😂
Have a look at the Highland Boundary Fault further south, which separates the Highlands from the Lowlands. The small town of Comrie in Perthshire is known as "shaky toun" as it's right on the fault and gets dozens of small tremors a year. It even has the world's first seismology station, built in 1840. It's a lovely area to visit with fantastic scenery.
Haha that’s where I live!
I live just above the Highland Boundary Fault, on the Loch Long Fault. I remember experiencing an earthquake here in 1985. It was quite a loud bang followed by a violent shoogle. I thought there had been an explosion nearby and that our house had slipped down the hill. Of course it hadn’t but an earthquake isn’t the first thing that comes to mind when you experience something like that in Scotland.
@@kirsteneasdale5707 so you guys are directly on a fault and you have tremors but no big earthquakes?
@@jal-kx6tmprecisely. I'm certainly not a geologist but I guess the strength of the quakes depend on how "active" a fault line is. The ones in Scotland don't move that much these days, hence the quakes are small.
That's my understanding, at least 😂
It did this to make a perfectly straight line for Nessie to swim through when she wants to leave Loch Ness.
Nessie has evaded capture for decades without even having the ability to turn. Magnificent creature
@@MikeSugarbaker Magnificent creature....or log.
I thought it was to stop wild haggis roaming to the South
@@Davey-Boyd Wild haggis never leave the mountain they are born on. Interesting fact - they also never move up or down a mountain, they remain at the same elevevation they were at birth because females have longer legs on their left side, males on their right, so females can only walk around the mountain slope clockwise and males anti-clockwise.
Originally, Nessie swam along the Laurentia coast and then almost got trapped in Loch Ness when the continents collided, luckily as you state she can leave along the straight line whenever scientists come to find her :)
Slightly further south is the Iapetus Suture, which is what separates the Laurentian plate from the Avalonian plate. It runs close to the Scottish border, down through the Isle of Man where you can actually see the bare rocks, and through Ireland down to the Shannon Estuary. It's had a huge effect on history.
Cool! Thank you!!!!
Noice!
All I saw was plates, now I'm hungry
Y
Such knowledge . Dope
hello a scotsman here from glasgow, another thing also is we built the caledonian canal along this fault, so we connected all the lochs and waterways along the full length of scotland, so you can get a boat from the atlantic ocean on the left to the north sea on the right, you can hire boats and do it if you wish.
This government project started in 1803 to allow warships to move readily and safely from the North Sea to the Atlantic. It was completed in 1822 - just as the introduction of iron steamships re-wrote the rule-book leaving it effectively obsolete. It has been used for small freight vessels and, increasingly, pleasure craft.
It's all Feng Shui.
Since dragons can only run in straight lines, this feature makes Nessie feel at home.
That might be so. I'm Danish so it's definitely not my fault.
Ohh I like that answer.
Nah it’s caused by Excalibur,
It was the final battle
When you travel from one side of the fault line to the other, due to the plates being made of different types of rock the scenery changes completely. From a brownish, rounded-off quality to the hills and mountains in the east, to pure grey granite with very little coverage of moss and plants in the west. It's like suddenly stepping into Austria 🙂
Not dissimilar to the change in the Peak District at the great ridge between Edale and Hope Valley. To the north is sandstone (millstone grit), forming the domed mountains and moors of the Dark Peak; to the south is carboniferous limestone, forming the dales (plateaus and valleys) of the White Peak. The change and contrast is sudden and dramatic.
I can confirm this, I live in the thing, on one out of my bedroom door I see Austria, from my conservatory I see the alps
@@chiefsdad its nothing like the peak district, that doesnt even belong in this conversation
@@IndigoBikeTouring who made you the arbitrator?
Fascinating observation! I must go and see

The whole scotland mission I was thinking of this specific line
My first thought hahaha~
Always amazes me as you drive north across it. The total and pretty abrupt change in the scenery. It's a very special place.
Cross that line on the right train route up from London is the MOST amazing experience.
*You have arrived in Scotland!*
Wrong line - *I was thinking of the one far closer to the national border, and it is not as spectacular as the Great Glen.* It's beautiful on it's own though.
It's as you go up the A9 north of Stirling it kicks in
It's stunningly beautiful.
@@MP-fw4ubthat road 😬
Some arial view pics of what it looks like from above would have been a nice compliment to this interesting topic.
Yeah, weird - I have more questions than before I watched this video. Bit rubbish really.
A lot of my PhD was on this. I studied how magnetic fields interact with the carbon in the Iapetus Suture and Variscan orogenic faults and this enabled me to find where the former ancient ocean bed residue was, and allowed me to make 3D models of the Earth's crust in Ireland.
Now that is cool.
That's amazing 👏 I'd love to see it. Is it available online?
Interesting
Now that’s the coolest thing I’ve heard in a while!
Yes! We’d love to see your work!
I live in that valley. The Great Glen. Very scenic.
Can boats go through the valley? Or is it not actually covered in water?
Wow I visited Scotland would love to live in those hills
Tj4234 can you travel from one side of Scotland to the other solely by traveling the Great Glenn fault line valley?
@@ImTHECarlos98 yes they can. There's a canal that runs through it. Only small boats though, it's not a wide canal. The Isle of Skye is the large inner island that looks a bit like a wing. It has some high mountains on it. That's roughly a viewing distance of about 200 miles.
@@Daniel_leading_the_13_Plateans if you stand at the tip of the Great Glenn on its north eastern side, you can actually see the Isle of Skye in the distance (because the Great Glenn is below sea level like the video says).
My fault too. Those of us educated locally who took Geography to Higher are pretty familiar with all the details. That straight line extends way beyond the sea shore at Caol or Inverness and can be seen extending at least to Mull and perhaps Islay and Jura in the South and to Tarbat Ness and maybe even Wick in the North. As major faults go, it's pretty quiet. Earthquakes in the UK are almost all less than 4.5 and activity here is usually a lot less than that. Only one event directly on the fault in the last 60 days (BGS) and it was 0.8.
The glaciation has carved out a trench that reaches down to around 300m to 400m below sea level and at four places along this trench it is filled with glacio-fluvial deposits to above sea level. These allow Fort William, Laggan, Fort Augustus and Inverness to provide home for around 70,000 people and prevents there being two separate islands. Loch Ness is the largest and best known of the lochs that fill the gaps between these plugs of sand and gravel. It has a muddy flat-bottom due to deposition from huge catchment area and is a maximum of 223m deep (surface elevation 16m).
I always get a laugh when construction projects run by people from elsewhere start drilling in central Inverness trying to find bedrock without understanding that it is several hundred metres down. The BGS database clearly shows results from a 19th century drill exploration to nearly 100m and all it shows is sand and gravel with occasional minor clay deposits. The buildings all seem to stay up!
Its a Problem we know from Fault Lines where stress builds up only very slowly (if at all): We don´t know what they are capable for. Strong Quakes on such Faults are rather 1 in a 1000 or 10 000 Years events. The Fault line (or fault system) is certainly still active. I could imagine a new Episode of Activity started after the End of the last Ice Age when the Retreating Ice Cover let the ground bounce back which induced pressure onto the Faults.
Quakes which could be attributed to the Great Glenn or nearby Faults are a 4.3 (USGS) in 1974 and a 4.2 (USGS) in 1986. Noteworthy also a 4.6 (+/- 0.3) near Inverness in 1816 with Intensity 7-8 (via Archive of European Earthquake Data). A 1 in 1000(0) Years Quake could easily be a M6 one.
I can tell it ain't my fault. I'm from Denmark. But nice and interesting fault.
It's so we can have lochs deep enough to hold monsters in.
The most logical explanation 👍😀 Love it!
And hence the lochness monster
Nah its the Monloch sterness
🤣
So we’ve found where Godzilla & Mothra have come from?
I can tell you that here in Connecticut, on the East side of the river, is definitely proof that Scotland and America did indeed collide. The soil and rocks are the same as they are in Scotland. On the western side of the Connecticut River, the soil and rocks are completely different and have almost none of the same qualities. I’ve lived here for over 50 years and I also enjoy Geology. Specimens are VERY different! 🇺🇸🕊
Namibia also shares geology with areas in Latin America.
@Karen S Hi! You wouldn’t happen to be talking about Devils Hopyard, would you? Lots of crazy noises there! 🕊
I heard something similar from coal miners.

Have you ever done an episode that talks about the Appalachian Mountains and the Scottish Highlands being a part of the same mountain range?
Not just those two, big parts of the norwegian mountains are also part of the same orogeny.
Atlas mountains too or evidence suggests they are
Fun fact! Nearly every Loch in the Great Glen has its own Loch Monster.
"Nessie" in Loch Ness
"Wee Oichy" in Loch Oich
"Lizzie" in Loch Lochy
And even some rare sightings of one in Loch Linnhe
Many of the surrounding Lochs also have their own sightings in Loch Garry, Loch Quoich, Loch Arkaig, Loch Morar, and Loch Sheil.
Personally I think they're all the same species migrating across the highlands through the river systems that connect the lakes together.
The line is a result of things formed during Caledonian Orogeny... So Scotland is an...Orogenous Zone?
Found Eccentrica Gallumbit's YT account.
I know it's a joke, but also, yes, that's the term for a region characterized by mountain-building 😂 geologists have a lot of fun
@@davidnewtown8774 That's awfully gneiss of you not to go after the low-hanging fruit.
@@zadtheinhaler schist, that's the pun I was going to use
The great glen hasn't been an orogenous zone for a very long time - its very old and inactive.
Was hoping you'd mention the Scottish Highlands were once connected to America's Appalachia
Indeed ithey were. Some of the most ancient mountainous areas in Scotland were once part ofthe Central Pangean Mountains, which include the Appalachians, the Little Atlas of Morrocco and much of the Scottish Highlands. Here's a bit on the Great Glen Fault, which actually continues on the other side of the Atlantic:
en.wikipedia.org/wiki/Great_Glen_Fault
The Highlands are still connected to Appalachia, in the hearts of thousands of Scottish descendants!
@@rogermac358 funny, when I read the ops comment that's what I thought of.
Yea. Too bad they didn’t
My Scottish ancestors (really only a few generations ago) from the Highlands settled along the Appalachians here in New England. Makes sense they felt at home here! I long to visit the Highlands someday and our ancestral castle. Long live Scotland!
I just walked Great Glen Way by Loch Ness from Fort Williams all the way to Inverness there, was quite amazing.
I'm hoping to do it soon. I've done the west highland way the proper way and I've been up the Highlands every year since. Glen Coe is my favourite place, it's majestic
@@1nikg Its epic
Fort William
I learned about this some long time ago. But just as I reread a good novel I love to be reminded about stuff. Often there is new bit of infirmation as a bonus. Thanks.
About 300 million years ago, there was quite a massive mountain range called the Central Pangean Mountains. The Scottish Highlands are part of the remnants of those ancient mountains that were once as high as the Himalayas. The Appalachians in the US were also part of that range.
@Ricky Barber balls
I'll quip: I don't think it was called anything 300 millons years ago. 😏😊(😄)
@Ricky Barber No, you're wrong. We know how old something is based on a combination of stratigraphy and actual radiometric dating techniques. It's possible to date some rocks very precisely based on the decay of certain isotope (here's an example: en.wikipedia.org/wiki/Rubidium%E2%80%93strontium_dating). Other times, we can see what order rocks appear and compare this with the local and greater area. If you have any specific questions, feel free to ask.
@@leticiaromano6054 I wouldn't bother. Ricky Barber is obviously willfully ignorant. He doesn't want to learn. He only wants his worldview upheld. His ignorance is his bliss...
You can tell yourself anything, just as someone else can say anything. No one is right
Scishow: It happened recently
Me: oh cool when?
Scishow: 66 million years ago
Me: huh. For some reason I was expecting it to be like more recent than that

I was expecting 60 years ago, not 60 MILLION years ago XD

@@NarwahlGaming Trip is in July 2024. We are preplanning to get the most out of our 7 day visit.
So interesting that the Scottish Highlands and the Appalachians once connected. There is also another weird absolutely straight line valley in Tennessee called the Sequatchie Valley, where I grew up. It’s clearly visible on Google Earth.
Add to that the St. Lawrence Seaway, which is Lake Erie, Lake Ontario and the St. Lawrence River, which form an almost straight line along the northern edge of the Appalachians and the two lakes are part of the border between Canada & U.S..
Maybe that’s why so many Scottish people settled in the Appalachian Mountains
@@thomasshepard6030no, that's where the English on the shephelah forced us to live. They wanted us as a shield against the Native Americans, and had no intention of letting us live with them. Yes Walden Ridge runs from TN to Europe it plays out in Germany.

@@ericvanzytveld9034 he explained how this happened, but not why we don't see more of it.
@@joshuadempsey5281: it's also a 2-min video. I'd expect he'd say more if he made a 5-min video. It's also possible it's that rare, that just the right set of circumstances worked. Other locations have different sets and different results.
@@joshuadempsey5281
Partly because its not always straight. The San Andreas Fault in California is the same type of strike-slip fault between two plates but its bent due to the Sierra Nevadas. Southern California is where it bends. In many places where two plates are against each other the plates are moving towards each other. Such as India into Asia or Africa into Eurasia.
Freaks of nature? There's a straight mountain valley in the Canadian Rockies that is 600 miles long. Those are rugged upthrust mountains and geologists have no idea how the crust managed to break in a straight line for that far.
This is really interesting and informative. Thanks for the video.

Oh bonny Scotland
Caldonia you calling me!
There's a similar fault on the southeast/eastern shore of the Great Slave Lake in Canada. The Great Slave Lake Shear zone runs through there, and can be seen from space, despite it not being active in well over a billion years. It is from the Taltson- Thelon Orogeny, and is related to the Trans-Hudson Orogeny, which formed the geologic core of Laurentia 2 billion years ago.
Good sense of humor!
Nice bit of info there ❤

What is also interesting is that the brown rocky formations around the GGL are molecularly exactly the same rock that New England “Brown Stones” are made from.
I´d guess it´s really the same rock. The oldest central parts of the Appalachians are also Caledonian Orogenesis, and the North Atlantic opened much later and tore Laurasia apart, so parts of the same old Brown Stones are now on both sides of the pond.
Excellent, never knew that. Thank you 👍
Awesome facts
I always wondered too tbh, I am into war map games and seeing the valley line on Scotland made me curious.
I've been wondering why there is a line in Scotland for a while but never had the balls to figure out. God bless you for making this
