The Double Impact Crater in Canada; Clearwater Craters
Вставка
- Опубліковано 12 чер 2024
- One of the most spectacular impact craters on the planet is located within Northern Quebec in Canada. The area contains two immediately adjacent impact craters which are known as double craters. These impact craters each measure more than 20 kilometers or 13 miles wide and occur within a remote section of tundra. Known as the Clearwater Craters, they formed when two separate asteroids slammed into the planet more than 250 million years ago. This video will discuss how these ancient impact craters formed, and how frequently similar impacts occur on the planet. This video was made by a geologist who is based in Arizona.

So, what are your thoughts on this unusual coincidence of impact craters?
An anomaly ! Sort of like the Hawaiian volcanic hole that migrates across the plate.
The Canadian Shield is full of impact craters. It's not much of a coincidence that two large ones happen to be close.
@@TheBrandoncarter its an area which is not volcanic, and not much happens to erase them. That just means alot survive which otherwise would be lost due to erosion. YOU are sat on top of an impact event even if you cannot see it.
@@TheBrandoncarter yep! If you look around, almost everything with a clear resurgent dome in the center of a semi spherical lake is an impact crater
I like the series of impact craters. But let's hope it is not to be continued soon.
P.S.: might be you want to look into mouth clicks? Your audio has some ASMR vibe to it 😢
Cool
It is definitely a fun geologic feature to look at, although largely only noticeable via aircraft or satellite!
Never took you as the kind of person to enjoy geology but you're certainly right, its very very cool :)
"We keep hitting ancient Quebec but it just... won't... separate from Canada."
*Ancient baguette noises intensify.*
It is defacto....😀
@sploofmonkey Yeah, Turdo the father put the army against us and proceeded to more than 500 illegal arrests...
@sploofmonkey Yeah, they fought with dinosaurs
Comment below for specific topic....he didn't ask morons for trash 🗑️
Well, here's an addition to my bucket list.
Now try getting there!
@@vipahman It will be an adventure!
Been here and fished with my father . fantastic pike fishing and the land is beautiful
Nice pun.
U cant go there
This gives me hope I can win the lottery.
Can i buy a ticket with you ?
You won't, I'm sorry.
Nah the chances are even lower lmao
In the span of 480 million years, you might win twice!
u can win in a million years
absolutely loving this series on impact craters. I've always been fascinated by them!
Fascinating from after the fact right hahaha
They just hit different
i really love channels that dont drag out the videos to 10 minutes, good job
And outta nowhere, I found this beauty of a lowkey channel. Fantastic upload!
My favorite crater channel hands down LOL
Speaking of the Shoemaker-Levy 9 Impact, I'd love to see a video about the Nördlinger Ries, which was first proven to be an impact crater by Eugene Shoemaker in 1960.
The Nördlinger Ries is a impact crater in germany that formed at the same time and at the same area when the Steinheimer Becken formed
How does the meteor get through the firmament? It just doesnt make any sense.
It’s also responsible for a fascinating tektite gemstone known as moldavite! :)
As a Canadian, we know these lakes also as ‘ole smiley’ as it looks like a smiley face waving his hand saying hi.
That is just so adorably Canadian.
Enjoy your videos and look forward to them coming out.
Damn, Quebec and central Siberia must have done something to really piss off the Oort Cloud back in the day!
This was amazing, it is possible to do an incredible canoe trip through these lakes to a lake just north of here (Petit Lac de Loups Marins) with the only known population freshwater seals other than lake Baikal leftover from the ice age. From there you can travel down the Nastapoka river to Hudson Bay. This being said, please talk about the Nastapoka arc.
I could not help thinking that if Quebec was further south in a warmer temperate climate or the current interglacial was warmer, the islands in the western caldera would make an easily defensible circle of walled towns connected by sturdy bridges.
Insulae Aquapolis. Rock on Middle Ages!
… And I would not have to shovel meters of snow off my driveway 6 month per year, tabarnac!
This is a brilliant idea for a book
Not a good idea to build a town in a place where meteors are falling
@@hyun1141 we have solid umbrellas. We have no fear.
@@hyun1141 wont hit twice in the same area, oh wait...
Excellent video. Thank you.
is the east side of hudson bay an impact crater, i always thought it looked like one
Great walleye fishing up there.
No reason to make fun of their looks.
I always find it interesting how you are able to determine the size and speed of these objects.
This is so interesting. Love it
Very good content!!!
New Sub, really enjoy your videos, thank you for the information.
I love your channel.
Any chance of covering Woodleigh crater? Love your videos.
This amazing... Imagine two different impacts
Can you do a video about the Bungle Bungles in Western Australia?
It may have been a brutal event, but it left some beautiful lakes.
Fascinating!
Thanks a lot 😊 i live in sherbrooke Quebec ! Very cool description 👌♥️
Have you guys done one on west hawk lake yet in Manitoba? Another meteor impact site
I was like "How in the hell do you know they happened at different times....... oh, okay, there's the answer."
Excellent.
Great vid.
Excellent 👍
Nice video! Could you do Vredefort crater? It has quite the history and is the largest crater of any sort on Earth.
Another idea for a video- how about doing one on Queen Mary's Peak which is a massive shield volcano on the island of Tristan de Cunha which is one of the most remote inhabited islands in the world!
that was interesting! I remember reading about a smaller crater in the prairies, found with radar mapping from the forestry industry or similar technology. cool
There are so many impact sites across Canada
Eugene Shoemaker was a greatly under-appreciated geologist. He did much more than get a comet named after him.
Excellent
Think about it...the endless cycles of glaciation of the last few million years could not erase any of those craters. The Superior Craton is made of hard, igneous and metamorphic rocks.
I was having similar thoughts.
I agree, isn't God awesome? The heaven's reveal his handiwork.
God bless you
Far more likely their age testing Argon method is complete BS and the craters were formed with the ice covering Quebec.
@@w8stral Yeah, because glaciers can turn rock to glass with their immense heat.
@@garmancathotmailcom If 1 = 1 but you say C, these arguments do not equate. Try again.
Wow, what are the odds? I would've thought for sure that they were from the same event.
Whoa dude. That was a cool video
This is crazy. 36 Kilometers across?! How did those asteroids know about the metric system millions of years before it was discovered?
Amazing
An interesting and not generally-known fact of Clearwater Lake, is that there are seals that inhabit this lake. It is only one of two lakes in the world where seals live in freshwater, the other being Lake Baikal in Russia.
at 0:50 you can also see the manicougan impact crater just near the bottom centre of the image! Crazy 3 massive impact crater all so close!
My question is, how did the older crater retain its circular structure despite the supposed larger second impact just a few kilometers away?
The debris from the second, that likely did fill the first, was easily carried away by 130 million years of glaciation. Well that's my theory.
For the same reason bunkers are under ground and trenches are cut into the earth
Interesting timeline of 2 meteors hitting side by side. 250 million + yrs ago. Sudbury too had 2 meteors/objects smash in its area of the Greater city of Sudbury. The basin itself 1.8 BYA and Lake Wanapitei 20 MYA. Both are found in a (two overlapping) geomagnetic anomalies. I vote no coincidence on these two in the video as well. Looking at the big picture.
2 scarab looking lakes in Ontario too
Look at the massive scratch mark of lakes close to Clearwater East and West. Very neat, like a bears claw
Great video. Question ; Just west of these craters is a "half circle" on the Hudson Bay shore line. Is this a HUGE crater too?
Yes! Please discuss this!
It's called the Nastapoka Arc, and there is no evidence of this, although people have tried for decades to find any. The generally accepted theory at the moment is that it formed during a proto-continental collision up to 2 billion years ago as Laurentia was assembling, and the geometry just happened to make it an arc, and not a complete circle. One competing concept is that it represents an old crustal structure that was caused by an impact during the Archean, but the impact structure itself is long gone, leaving only the some kind of zone of weakness that later emerged, but again, no evidence other than the shape.
been watching a lot of your videos about craters lately, and it makes me think. is the Eye of the Sahara maybe a crater?
Have you done Vredefort Crater or Sudbury?
Woah that's wild
Travel there, and back would be quite an undertaking. Gonna want a good pilot for that trip.
0:50 I guess I'm not the only one to think the Eastern coast of Hudson Bay is suspiciously circular. I checked Wikipedia and it's all conventional geology until "a major unconformity separates Upper Devonian strata from glacial deposits of the Pleistocene. Except for poorly known terrestrial Cretaceous fluvial sands and gravels that are preserved as the fills of a ring of sinkholes around the centre of this basin, strata representing this period of time are absent from the Hudson Bay basin and the surrounding Canadian Shield."
I wonder where all that rock went? I wonder how it went?
The semicircle is later discussed; impact is considered unlikely but not ruled out.
To what extent did the second impact fill in the crater of the first impact?
Cool... There's lots if you look. Meteor lake in Manitoba is another one... They're everywhere.
Like you gave angle of impact on first impact but didnt on the second and the direction of the impacts would also be nice to find out
서쪽 운석공의 가운데에 있는 두 번째 고리는 충돌할 때 지구 내부구조의 반향에 의해 생긴 게 아닌가요? 이중운석공은 보통은 그렇게 생기는데....
The odds of that happening must be astronomically small?
The odds of us existing is even more astronomically smaller...
If I’m remembering right there’s a spot on the moon where there’s a crater in a crater in a crater
@@noelvalenzarro you can also see the splash marks of one massive impact and loads of craters next to each other 👍
What are your thoughts on the very circular shape seen in the Hudson Bay, basically westwards of the Clearwater craters? Scientists haven't been able to discover why the shoreline is so circular, and one of the main hypothesis is that it is a ancient maaassive impect crater.
It has the shape of a giant impact crater. But geological evidences are yet to be found. When a big meteorite hits the ground at several miles/second, the resulting high temperature and high pressure of the shockwave leaves many signatures, like fractures in the rock and impact metamorphism. Not found yet on the site.
@@alainrobillard4300 Yeah. Not enought evidences. I wonder why it is so circular
@@augustolobo2280
You're not the only one to wonder why. As a matter of fact, if it's origin was a meteoritic impact, it would be the biggest of them all, and the event would have nearly eradicate life on earth.
@@alainrobillard4300 if they do find evidence of an impact there, it could easily be the cause of an extinction event, like the crater in the gulf of mexico
You should cover the Nastapoka arc. Very strange feature, also in Quebec.
Absolutely. Always doubted the "settled" science about this.
@@bob_frazier I personally wouldn't be surprised if it was related to the Barberton Greenstone Impactor, the crust in this area is pretty damn old, and erosion is pretty good at erasing signs of major events that old.
@@bob_frazier There's still some debate, but even the people still arguing that it's related to impacts have given up on claiming it's a crater itself, only that it represent old crustal weakness formed by an ancient crater that long ago vanished.
Astronomy has been my field since a child. Loving the meteorite series. Could it be possible to examine the minerals of our nearest moons and planets at some point?
Maybe do a video about Nuclear Explosion impact craters (if there are even any) or maybe about what a nuclear explosion would do to the ground/ how much of the crust is affected by the radiation. Something along those lines
Could you do a video about the Michigan Basin?
why would someone unlike this video?
Its a shame this channel only has 42.3K subscribers

Deep bay in Reindeer lake, Saskatchewan is a meteor crater.
I think I need to check that out .
What makes the terrain have this certain appearance? Especially the ring structure, with horizontal stretched islands?
I'm going with heavy glacial grinding and linear deposits. This area would have been among the thickest ice of the Laurentide ice sheet.
It is interesting that mounds form in some craters but not in others.
I get stressed out trying to fathom that amount of time. Even just thinking what the earth will be in a million years makes me feel so small. Very informative vid tho I’m gonna check out more of this channels content.
2 million years from now, everything a million years from now will be seen as prehistoric. Have a meaningful day.
What about the half round craters? Hudson Bay to the left of the craters on the main map do you think that's an impact crater?
Look at Hudson's Bay's shape!!! How did it become circular?? Very suspicious!
@@marktwain368 I think so has anyone looked in to it
Look up "Nastapoka arc". Because of this circular shape it has been speculated that it's an impact crater, but there is no evidence of it. Bolides leave behind noticeable fractures and very specific types of rock due to the force of the impact, but none of these typical markers are found in that area.
@@desmond-hawkins thank you I'll look it up . Maybe it's an old super volcano rim
To the left at the shoreline it looks like a huge one
The formation of castle "rock" in castle rock CO might be an interesting video
I wonder if the east coast was an impact crater. It is so rounded, and if you follow a straight line north west from it, there are a series of craters running into Quebec, like a bunch had rained down at once.
That’s just erosion like everywhere else
It seems impossible that separate impacts would be so close together until I remember how cratered the moon is.. We've obviously been bombarded with impacts but most of the craters are eroded.
There is a possibility that the impact of Clearwater East was far more spectacular. Its location is exactly aligned with four other impacts occurred in the Middle Ordovician dated about the same age. Considering uncertainties about dating of the meteorites of the Ordovician Meteor Event and hypothesizing that all these occurrences were simultaneous, Clearwater East could be just one of a series of impacts spreading from Laurentia (future America) up to Baltica (future Europe) with even larger possible craters as the Ungava Bay and Akpatok lake. May I share your video in my blog to illustrate this theory of mine?
Whoops... it's not Akpatok, it's Akimiski... sorry.
Love impacts.
Could you do "Cerros del Rio Volcanic Field"
its a huge volcanic field and i would love to hear it!
Its the millions of lakes for me, crazy.
The odds aren’t that remote. Observing craters on the moon, you find many craters containing multiple impacts within them.
Ordovician trilobite: Lightning never strikes in the same place twice, so I’m safe from meteors in this crater!
174 million years later:
Second meteor: That’s just a myth!
What and amazing coincidence side by side impact 200 million years apart? You sure about that!
Lol and people say " lightning never strikes twice in the same place"
I'm wondering if the 2nd of the two was metallic and potentially a precious/semi precious metal mine. (yes the lake would be a problem)
No. Meteorites of useful size are mostly vaporized.
Like lighting hitting the same place twice
What was the last asteroid of similar size to hit? Ive tried looking but everything I find on google talks about super old ones. I know there have to be more recent ones that have just been eroded or covered up. Are there any we know of besides Tunguska. Like one that actually hit?
Wasn’t their one in Russia not long ago that caused 2 billion euro in property damage.
@@Akechi_The_Phantom_Detective Not an impact as it blew up in an airburst
@@KaiserStormTracking right fair enough then wouldn’t it be the Whitecourt impact in Canada? Or if we’re going to be honest it’s probably one at the bottom of the ocean.
Following. I'm fascinated by asteroids.
@@Akechi_The_Phantom_Detective Idk
But the latest impact was near Norway's Capital 40 miles to the west
Dam the odd of that happening boggles my mind
Correct me if I'm wrong but don't they use argon dating to determine the age of lava flows, which has proven to be inaccurate?
Argon Dating isn't inaccurate but all dating methods are inaccurate to an extent
What are the odds they would hit that close together
Since we're on this topic you should do one on the Manson Crater, in Manson, IA out in the NW part of the state. It was once thought to have been the asteroid that killed the dinosaurs.
Suggestion: the Siljan ring impact crater i Sweden
So why do some craters do that uplift thing and others dont?
I can't decide if this is the safest place to live or the most dangerous.
So my assumption about them back then was incorrect. Even more interesting.
Wait …. So we can heat up Dwayne Johnson and find out the true age of TheRock using Argon39?
Yes...as long as "The Rock" is cooking!
This is like hitting a bullseye within a bullseye... but for asteroids.
I wonder if a meteorite is still worth collecting after a major impact?
It’s a Two for One … at First Glance but Check the Label ..
