As a Brit I'm constantly amazed how many Americans simply don't appreciate
what a magnificent variety of landscapes they live among ! From the Great Lakes to the Rockies , the deserts of South West and swamps in Florida etc.
America is an amazing place !! Don't listen to the whining critics !! 👍🇬🇧 !
I think most Americans living here don’t appreciate it as they have never seen what’s out there… if you see the Grand Canyon up close it’s far different than a picture. I think geographically the US has some of the best landscapes in the world… but Europe hands down beats us in architecture.
Ignorance is bliss. As they say 😮 :-/
Thank you for recognizing the beauty and diversity of America. Many of us do know how lucky we are to live in this amazing place.
As an Ohio native who grew up hearing the Michigan-bashing tales, I never had the chance to visit until I was an adult. Michigan blew me away! From crossing the Mighty Mac to learning what a Yooper was and trying my first pastie. Camped on the shores of Lake Superior near the pictured rocks during the summer solstice. Skipped out on Florida this year and plan on returning, hopefully this time I can find an Agate!
For the rest of us not anywhere near the Great Lakes, what *is* a Yooper?
@@worldadventuretravel as someone from Michigan's lower peninsula a Yooper is someone from the Upper peninsula. A U.P.-er
Aww, being a Michigan girl who's family has been here since well before it was a state, this makes me smile.
Just avoid all of our cities. Demmy's have done a master class on how to ruin thriving industry in 7 once beautiful cities
Try Chicago Lake Michigan.
You'll be amazed. Spring is nice.
Northern suburbs are best.
Crazy to think this episode is almost 15 years old, it really does bring back a lot of memories of watching childhood science documentaries. The music, the narrator, the effects, everything. Glad to have found this channel!
The synthesyzer haha
And I run away. That stupid over the top narrator, I can't stand him. Man, relax! Tell your boss they are crazy! They are! Yuck! Talk like you talk at home! Jesus!
And still, these American narratars, I can't stand it. Over the top. Exagerated.
I have to agree with you on this I didn’t know how to pay attention in 7th grade .
It’s great to see these documentaries today
this is definitely older. youtube is 15. videos cant be dated to before youtubes invention
It's no mystery. The Great Lakes are *entirely Canada's fault.* For thousands of years after Zambonis resurfaced ice rinks, the shaved ice was dumped outside, eh?
No, we put it in our beer coolers
Sorry
Take Off, Hoser
Huh???!!!
Blame Canada
I lived the first 18 years of my life up between the Copper Harbor area and the Soo. Now I live right on Lake Michigan. I cant imagine being away from these Insanely beautiful lakes.
I live close to the Huron coast in Ontario. Lake Huron is my favorite
@gryph01 - Once you connect..really connect with these Lakes, you know that's where you must stay. I wish I could explain it, but I can't. When I lived in the UP, it sounds crazy but the big storms-the downright vicious ones would rear the lake up on her hind legs, you're memorized. You can't help but feel them in your soul. And you really realize how small and insignificant you, your trouble and worries are..
Sault Canada here...I've circumnavigated Superior by Land. our north shore exhibits the glacial deposits mentioned...lots of smooth stone. Great smooth cliffs that plunge to the water. ✌️🇨🇦👍
@@BrianPeloso-ln4ry Nice
@@BrianPeloso-ln4ry:I would love to drive the Lake Superior shoreline on the Canadian side.
MN born and raised and my fav city is Duluth, and I am in awe of lake Superior and how destructive and powerful it can be!
the lake it is said, never gives up her dead when the skies of November turn gloomy...
I'm from London Ontario, but I've driven past Lake Superior many times driving to Calgary and it is my favorite for sure. It is like Ocean water in a lake surrounded by beauty (at least in Northern Ontario)
Go to canal park brewery, best food and beer in Duluth.

You can take the man out of Michigan, but you can never take Michigan out of the man.
Born and raised here, and I’ll be buried here a true gem to the continental United States. No other state in the lower 48 can really compare and I’ve been to most . Colorado and it’s pure beauty would be a close second in my book..
No truer words spoken. Love this land.
Nope, AZ’s my close second. The distances twixt towns always reminds me of the UP. I was raised in Northern Wisconsin and thoroughly explored the UP but still only feel like I’ve barely scratched the surface - so much to see. But for all my screwin’ around, somehow I always seem to go back to the Sturgeon River. The river’s gorge, Canyon Falls, Tibbet’s Falls…she just makes my heart ache. I swear to God, before I pass I’m going to explore it upstream to where it starts.
Kayaking, rock climbing, skiing - the Upper Peninsula just has so much. Laf, except an easy living.
@@ronjon7942 I bought my first Estwing pickaxe in Copper Harbor.

Hell yeah Detroit. I from here and we out here doiiiin it.
Failed to mention Nestle and their giant siphon…
"too obvious it hurts YT brains" LOL

Yet Californians wonder why they have droughts 🤣🤦
Nestle uses way less water than your local craft breweries and wineries and bread yeast makers, like less than 1%. You just like to be angry.
@@JohnRHeil1 apparently you no not of what you speak grasshopper.
Try Googling "Nestle buying water rights to California aquifer".
California sold their (& 2 other states) largest water reserve to a private company.
Michigan is hands down the most BEAUTIFUL state in the summer, combined beautiful Forrest, farm lands and sand dunes and Beaches Michigan truly is a unique state and #1. I love winter so makes it even better when you get dumped on by lake effect snow.
Upper Peninsula is beautiful. Grew up on a farm in Southwestern Ontario (on the shores of Erie and visited your state often growing up).
Yeeeaaahhhhh this my state arf arf. This is my state I think.
Embrace it. As long as you can remove the snow and the gov does not infringe, MI is the best state there is.
@@terrybennetts7898much have the snow than the government any day lol
After watching documentaries abut the Fitz and all the other shipping disasters on the Great Lakes, it's the only think I can think about now when that region comes to mind. That and the "November witch."
And at one time the ice sheets thickness was supposedly at 7 miles thick, a lot thicker than 2 miles. The sheer weight of the sheet was so heavy it pushed the land around the great lakes down. The land to this day is still rising upwards from the weight being gone.
Yes. It’s measurable from satellites..
The Ice sheet depth over the Ottawa Valley 10km thick so the depts they propose in this doc is way way off. Now if we factor in the sun's pulse every 12K years. Pulse Water comes into play as all this ice melted very very quickly
Imagine the waterfalls back in that time. 5 to 6 miles high.
@@user-hw2uq1wc1dwith that height you’d think by the time it came down, it’d prob just be heavy rain/mist? Idk 🤷♂️
I'm in West Michigan, about 25 miles from the eastern coast of Lake Michigan... One of the craziest things about the Great Lakes for those of us living downwind, is the affect they have on weather. Even today, for instance, the sun is out now - in 5 minutes, it may be snowing so hard that you can't see 100 yards, and then sunny-ish again 5-10 min later. This will continue most of the day. There is no weather system in the area... but there are 30+ mph, 10 degree winds going over 40 degree water - so we get bands of heavy snow only a couple miles wide, over and over.
Even when there's not enough instability to make snow, there WILL be clouds. From Nov-April, Western Michigan is the cloudiest place in America and one of the cloudiest on the entire planet. It's pretty depressing, almost never seeing the sun for months, but it's not all bad - the water staying relatively warm like that means that when it's 20 below zero right on the other side of the lake in Wisonsin, it's still 10 above here. And in the summer heat, storms that drop tornadoes in IL & WI get out over the 70 degree water and frequently lose the punch they had, saving us from a lot of the worst damage. And, of course, there is having beautiful beaches at a freshwater sea to enjoy all summer.
You could be talking about Seattle or Juneau Alaska.
Yes Cherry 🍒🍒🍒 picking season in a few months 😋
@akeleven - Except for not being on an ocean, and the freshwater sea to enjoy, and storms that had been severe for hours in Iowa, Illinois & Wisconsin weakening as they leave land, go over the cooler water, and back over land in Michigan... but yeah, kind of.
Everybody knows oceans affect everything about the weather - part of my point was that a lot of people don't realize how big The Great Lakes are, and that they also have a pretty big affect.
@indianastan - Fresh-picked cherries are so good!!!
@@SamM-gl9zcIts the same downwind of Erie and Ontario. We get some of the worst snow, because both lakes often line up with prevailing winds. The fetch across a few hundred miles of open water and you might as well be shoveling the lake onto land.
Then there is the seich causing flooding. They behave like giant bathtubs. Because the lakes line up with the wind, surface water is blown to the east end of the lake and when the wind stops it sloshes back to the west side. Just like pushing water in a tub with your arm. Compounding the problem on Erie is the fact that the west end is much shallower than the east end so it doesn't handle the return slosh very well.
Some of us living in the Great lakes Region are so lucky to enjoy these Beautiful lakes & some have Gorgeous State Parks such as Pictured Rocks National Lake Shore Off Lake Superior!!! States like California, Nevada & Arizona are facing A water 💦 crisis 💯🤓!!!!
The SW water crisis is actually man made. It’s a water mis-management problem, created by minds and decisions of man,aka politicians.
I grew up in Michigan and brought up my family here. I will forever fight any idea/plan of a water pipeline to the west.
@@joyreno1034 I've lived in West Coast states my whole life (60+ years) and I support and agree with you. I wouldn't feel at all right about your water being stolen to be used here.
I live a mile south of the Great Lake Ontario! Proud to be a Great Laker!
Me too !
I’m 10 miles away.
Growing up on lakes Michigan and Superior and being interested in geology, I am convinced that the state of Lower Michigan is a giant impact crater from something that hit our planet and punched a giant hole into the edge of the land mass that would become Canada. After that sea water poured in and created the salt layer that underlies the state. I even approached a professor from the University of Chicago about my theory... he actually said it was his theory too and could be entirely possible. If you look ate the rock formation layers it looks just like an impact crater. Other academics say I'm wrong, but then go on to say that no one really knows the processes that created these unique features... but I'm wrong.
They think a comet that caused the younger dryas die off just when the glaciers started to melt and massive chunks of ice were stuck there and formed lakes. The impact signs are called Carolina bay’s. Very interesting
The Saginaw Bay is a recent meteor or comet strike.
Goog: "saginaw bay impact crater"
The deep underground salt under in the Michigan Basin is from way way back before Pangea. More like Gondwana age.
Is it tho?@judd0112
We know how they were formed. No impact involved. If the oceans were forced into these areas there would be proof of it.
I agree there has probably been at least one and probably more extraterrestrial impacts that have contributed to the formation of the great lakes. The lakes are very deep in places and glaciers alone can't account for such deep basins.
I’ve lived in the Chicago area all of my life and I took Lake Michigan for granted until I started to visit other states and see how differently water is treated elsewhere.
Why is it treated better or worse in other places? Chicago has had its share of bad water issues in the past and I think one that wasn’t too long ago. They started taking their water from the lake like 10 miles offshore and I think their raw sewage discharge was flowing into the water intake. I can’t remember exactly. But maybe you know.
@@judd0112Chicago reversed the river flow.
@@judd0112 Water is more carefully used in other states that I've visited, they don't have the supply we do. There hasn't been any problems with our water supply, when we get a lot of rain there is sewage that gets released into the lake which spikes bacteria. It's no problem for the water treatment plants.
What you never knew the lake closest to you ? You had to notice it well on vacation away from your area ?
@@johnsalomone5101; He’s just stating that he’s Appreciating it more than he initially did . I feel the same way living in Wisconsin & having some beautiful Parks to enjoy right off Lake Michigan Shore & Really nice beaches too. Visited Flagstaff; Arizona last year & property there has skyrocketed & also water distribution 💦 is A huge problem if you buy rural land & want to build property out there !!! In all the Mid-West States we don’t have that problem. Nevada, Arizona, & California are all facing A H20 crisis that we in the Midwest will never have ; at least not anytime soon !!!
Too many name and place bloopers, but this vid was better than most UA-cam presentation on the Lakes.
Right away called United States a continent.... 🙄
I'm not usually into these kind of documentaries but they kept it interesting.

Nice
my cottage is directly across from you on the canadian side
better be careful on what you think you learned and please do some proper research on this subject and re-educate yourself on some of the false information throughout this particular documentary. noticed many false statements.
The tinfoil example annoys me because he's not even trying to hide the fact that he is just barely setting the 'clean' ice on the foil while he is actively pushing the 'dirty' ice down to cause as much damage as possible. XD
I saw that too, but he needed another prop and the cameraman was already there
Why did it annoy you ? What he stated was a fact which he did his best to illustrate while being in the Middle of nowhere ! If it had been Graham Hancock you would have
called him a genius ??
@@2msvalkyrie529 LMAO nah, hanckock is a complete quack. It annoys me because the example would have worked fine without him very obviously pushing on it, by doing so it makes it seem like he doesn't trust his own example.
what they dont go into is the area was under a massive inland sea during the cretaceous period , the Niagara Escarpment is an ancient coral reef cutting north from Niagara through Southern Ontario to beyond Georgian Bay.... at places its a few hundred feet above the current level of Lake Huron .....
It forms a crescent and extends down the western edge of Lake Michigan.
The Niagara Escarpment is composed of dolostone, not coral. Although one is uncertain whether or not that section of Pangaea had the tropical climate necessary for coral to propagate.
its Impressive in its own right :)@@ronaldviens7862
its impressive in its own right :) its full of fossils @@ronaldviens7862
Yeah, and down to the Milwaukee area. We’ve done some fun climbing on it in Appleton (High Cliff), Hustisford (Ledge Park), and, laf, Niagara too! - although Niagara, Wisconsin, isn’t park of the Niagara Escarpment.
I was born and raised near Detroit but my parents were from upper Michigan so I've been going there since I was born twice a year once in the summer and once during deer hunting. What amazes me is the place never changed, I'm 76 years old.
I was a child when my family visited Niagara Falls in 1969, when the falls were shutoff. It was a sight that told the story.
Actually, they were diverted because they needed to produce the necessary power.
@@spuds6423no, they were diverted to try and reinforce the face of the rock to slow erosion caused by the caprock calving off. Due to the Niagara Commission treaty between US & Canada, the amount of water diverted for night time hydro drives pumps which fill two massive holding ponds. However, I think 70% of the summer flow has to go over the falls all the time. In the daytime tourist season hours that is increased to 85% of the flow.
At a state park downriver (north) of Lewiston you see about a foot of temporary river height in the morning when both more water is going over the falls and the storage is being released through both the Canadian and US hydro plants.
There’s always something surreal about seeing a place on a documentary, tv show, or movie that one has personally visited.
The Wild Rice evidence is interesting, but the premise doesn't doesn't "hold water" (pun intended) for me. I'm a Landscape Architect with most of my experience in natural restoration and I have some familiarity with Wild Rice. I've planted it on my farm in a shallow and very calm pond less than an acre in size, and it did just fine. Wild rice was and is to this day, cultivated by Native people here in Ontario in muddy shallow lakes, that is actually where it tends to thrive. It likes nutrient rich, muddy bottomed fairly calm water at depths ranging from consistently saturated mud, to about 60cm or 2 feet of depth, it can grow in greater depth or less moisture, but a heavily wave battered shoreline is certainly not what it likes.
Yes, wild rice is cultivated in shallow muddy wetlands in Michigan also.
You are correct native Americans/first nations of that region did cultivate wild rice. That doesn't mean it wasn't brought here originally by the geologic forces discussed in the video. Once brought into the area the wild rice thrived due to favorable environment and conditions.

They should have added St Davids creek that was where Lake Iroquois "Ontario" flowed into Lake Erie prior to Niagara falls existence. Niagara falls was formed around 4500-6000 years ago with the aid of Glacial lake Tonawanda.
Check out the "Great Flood of New York" by the Woods Hole Institute...very interesting
@spuds6423 Look into the history of glacial lake Tonawanda. I'm very familiar with the subject.
@@swampman5014 Cool!! Thanks for the information....Ice Ages are Climate Change!!😂
I live on the south Shore of Lake Erie & I'm 48. I can stand witness to this fact!! Don't have some of our fishing spots anymore & the residents on the shore have been dumping broken up concrete from old buildings that get torn down to try to slow down the erosion for decades!!! GREAT VIDEO!!! ❤ (and I also hear that residents along the shore in Cuyahoga County have to deal with rats)😝 I'm trying to move Southeast about an hour!! The city areas really have too many people in them!!
The early lakes were salt water. We mine salt below the lakes and rock layer covering it.
Nestle - that"s where the water is going.
Glacial grooves don"t exist only on Kelley's Island. Middle Bass Island has them. They aren't as grand as on Kelley's but they are there. You just have to know where to look. I worked for a bit on a college practicum in the very late 1980s on Middle Bass. Lonz Winery was still operating.
Love those glacial grooves. I found a nice hand specimen of a glacial groove near Cleveland. Honestly one of my favorite rocks I have
As a Wisconsinite I feel so lucky to live near the driftless region and the Great Lakes.
EXCELLENT - really informative. Thank you, Spark
Thank you for this. I grew up near Lake Erie in Lorain County Ohio. As a child I saw the lake heavily polluted because of industry,Now thanks to changes in industry and the Zebra mussel she is a beautiful clear blue. Still not pristine. My father who was born in either Fairport Harbor or Lorain in 1895 and loved the lake told stories of fishing for yellow perch and the now extinct Blue Pike; and saw Sturgeon piled up along the shore because it was considered a trash fish good only for fertilizer. For reference I was born in 1946, a post war baby boomer to my mother born in 1908 . my father fought at Chateau Thierry Sept 14 to 18 , 1918.
thank you ...i live in michigan and you just explained everything we never learned in school...keep up the great work very interesting and knoledgable
Breh
When I went to Illinois to see my son graduate from Navy boot camp, we stopped on the shore of Lake Michigan in Chicago. I was simply floored. I stressed to my sister, "This is FRESH WATER! No lake should be so big that you can't see the other side!" We saw ocean-going vessels off in the distance. I mean, these Lakes are seriously humongous. I live in Ohio now, bordering Lake Erie and I'm sad to say I haven't actually seen it yet, but I'm hoping to some day.
I sailed Lake Michigan for a good chunk of my life. It's amazing how beautiful it is when you're out in the middle, no land in sight. Especially at nighttime. Just an incredible experience each time I crossed.
I am from Michigan and have not seen any major changes in the Great Lakes water level in the past 30 years. Some years the level is up and some it’s down.
They are climate shills.
Ahhh, Niagara Falls is between Lakes Erie and Michigan?? Really. Better check their maps. Last time I saw one, they're between Lakes Erie and ONTARIO. Good editing work there!
I live on the island in the middle of those two lakes. Erie and Ontario that is! One foot in each!
@@christinewittmann1806🎉.
Real nice.
To be on an island.
@@christinewittmann1806there is no island you can do that on. Lake Erie and Ontario are separated by the Niagara river. Grand Island is in the river and because of the falls no one would consider it part of Lake Ontario. If you're trying to claim the south western end of the Niagara Peninsula is an island just because some humans dug a ditch across it a couple hundred years ago, then the Erie canal has you beat by at least 50 years.
@@RowanHawkins I misspoke, a foot in each culturally. Yes, Grand Island is in the Niagara River which is miles long and connects the two lakes. Living in this region is interesting because you can very literally spend part of your day on Lake Erie and drive less than an hour to Lake Ontario.. I am sorry if I misrepresented my home geographically.
This documentary reminds me of falling asleep on a desk in highschool

We really don't know the cause of such geological features but it's fun to listen to people who claim do
Absolutely Fascinating. Living in Michigan , not far from Lake Mich , I Loved this from Start to Finish.
Should have mentioned the Alpena-Amberly Ridge which cut Lake Huron in half

Lifelong MI resident. I'll guard these Lakes with my life if it ever comes down to it. If you plan on visiting, I sincerely hope you treat them with the same reverence. Lake Michigan beaches get decimated by tourists. Their kids dredge channels from our streams to the lake and decimate the local habitat. Our lakes are a more sensitive ecosystem than an ocean or sea, even if you can't see across them.
That's absolutely amazing ❗❗
I tip my hat to those incredible scientists, well done....a bunch of huge lakes now have a complete story, timeline and a future.... cheers to you 🤟🎶
My Grandpappy had a cabin on Kelleys Island back in the 60s. These grooves were ALWAYS known as The Glacial Grooves. When we were kids, only about a hundred feet of these were uncovered, but since have have been excavated more for research.
I know approximately where the glacier stopped on the west US coast. I lived in Seattle and bought a new house. Just to dig a hole to plant a bush took an hour! The ground around Kirkland (across Lake Washington) is practically solid round rocks. I moved to Oregon a not a rock was to be found! I was so happy.
Lol same thing in Massachusetts.
Ya . . . around Enumclaw they called it hard pan I think it was. Hitting it with a pick was like hitting concrete, and it was just dirt and smaller sized pebbles and rock.
That could have been from the Tsunamis that have in undated the northwest coast repeatedly for thousands of years. And they are due for another one anytime. Not a question of if ,it’s when it pushed ocean rocks etc miles inland. Also the Montana ice age flood that glacial lake in Montana that was let loose and it flooded the entire western Washington carving the in not from the area but it looks like the Grand Canyon kinda. Massive water erosion. Went all the way to the pacific. And the academics didn’t think it was possible that if could have been eroded it such a massive single event rather than over thousands of years they claimed. Not new information has demonstrated that it was a huge event and it was not thousands of years was relatively quick on earth time scale.
I live on a glacier moraine with hardpan a foot down. The glacier is still only 30 miles away.
Answers many questions. Thank you for putting this on UA-cam.

I camp on manitolin Island regularly, and yes, the big water can be crazy scary sometimes
we needed this because no one ever talks about these lakes
at 7:50 'leaves behind glacial melt water' forming kettle lakes. This misses something key. As glacier melt/recede they leave behind erratics, rocks and boulders that have been transported. In this rubble are also large chunks of ice left behind like boulders. But unlike boulders this ice melts leaving a void a depression that fills with water as a lake. At the bottom of some of these lakes buried in the rubble and silt are bits of ice left over from the last ice age. The rubble and silt insulate.
Something else that is missing. By far the most powerful tool of ice and glaciers is the freezing thawing cycle that occurs along the margins. If you've ever climb or hiked along an arete, usually called sawtooth, jagged, or in Japan Dikiretto, you'll notice that a lot of the of rock is loose. This is because the thawing cycle allows water to fill in any crack and the freezing cycle expands the volume widening the cracks. Quarrying. The aretes are still there because this is what the glaciers on both sides were working at when they began to recede. This is where all the gravel, sand and boulders in glacier ice comes from.
'At the bottom of some of these lakes buried in the rubble and silt are bits of ice left over from the last ice age. The rubble and silt insulate.' Are you really saying there is still glacial ice there today?
Wait, what?? You’re trying to say there exists bits of ice, underground, underwater, from over 10,000 years ago? That there is such a dramatic NEGATIVE geothermal gradient that ice exists underground in the Great Lakes regions? That’s really the story you’re sticking with?
This must be how Alfred Wegener must have been viewed, although in his case he was proven correct.
Love how hard he pushed on the "dirty ice" compared to letting the smooth ice just side, even with that barley tore the tin foil! It took so long into the video to get to glacier when we all knew that already! 🤦
This was rather spell-binding. Just great. Thank you
Love this! I grew up 30 minutes or so away from Lexington harbor. Didn't know this. Fascinating...Very interesting to know the geography & history of the Great lakes!
Glacier's are lakes melting... glaciers carved the bottom of lakes cutting into the rock's learned this in middle school in 1987.
Michigan was under a lot of ice
@@murphyjulian7393heh, yep. Not underwater either, last time I checked.
Not everyone has your genius level
IQ...?
I live at the mouth of the St. Clair river and the water levels did lower by almost a foot almost 10 years ago but have come back up to normal if not a little higher. One big change is the ice, the river used to freeze solid every year without fail. The first year it didn't was winter 91/92 with mostly heavy pack ice flowing by and every since the pack ice has become thinner and more sparse often seeing the water between the ice. This year there was practically no ice, a couple of days of thin ice that formed along Lake Huron shorelines was about it.
Biggest freshwater delta on the planet
Right and the ice cover prevents evaporation or slows it down. I live in Macomb by the way and go fishing on Lake St Clair every summer. This year even the UP didn’t get much snow. My concern is the lake levels may drop as the climate gets warmer.
Global warming just a china hoax. Ask any republican😊
This was quite interesting. Thank you for supplying this video!
The house I grew up in was on an escarpment that formed an ancient shore of Lake Erie. Nowadays Lake Erie is about 5 miles from that location.
Oh wait, we forgot when the Army Core of Engineers decided to dredge it... RIP great lakes
lol
I hate programs that keep repeating a question before going on to address it.
It won't be much of documentary if they cut to the chase..
Made for TV. Question repeats show when commercials were played.
Interesting! I grew up right where the lakes got diverted and became the St Lawrence. (Kingston Ontario)

Lmoaooo this my state. Hooolllyyy. Shiiiitttt. I’m here arf arf doin it now.
The rising of the western lakes, aside from ice compression, could possibly be a result of magmatic activity under yellowstone. Its far away, but all solids are elastic to a degree and the energy driving that rise could strech that far.
Wait until Yellowstone decides to blow its cork again. Last time, probably had 2 miles worth of ice on top of it. Would have made for a nice little flood, eh…
I think you’d see more evidence for uplift between here (Lake MI) and Yellowstone as well for such a direct link. The lake basin uplift is measurable and well supported with consistent theories. Besides, the Yellowstone Caldera is actually sinking, not uplifting.
But…magma plumes simply have to be enormous, so maybe? Maybe there’s some magma plume wacamole goin’ on! :)
That's scary lol.
@@ronjon7942 The Yellowstone Caldera sinking may result in a compensatory rise elsewhere (albeit I would think, somewhat nearby). That certainly seems to be the case with the Hawaiian Islands. The Big Island is sinking under the weight of magma rising up through Kilauea while Haleakala on Maui experiences a compensatory rise.
Such a great documentary!
Fantastic episode!!
Clean salt free refreshing water. When swimming no dry skin, burning eyes, and salty dirty taste like an ocean. Pure michigan.
Yeah, swimming in the ocean sucks when you grew up near one of the great lakes.
"No salt. And shark free!" as the saying goes!
I live on the shores of lake superior and its awesome
Where? We used to sail/scuba in Ontonagon and Munising, so beautiful and the lake is so clear. There is just something so wild , untamed, even prehistoric about her.
Live in niagara region Canada my entire life , niagara gorge is auch a beautiful hike so different than anywhere else ive been in the world
Great stuff - grew up sailing the North Channel of Lake Huron, widely considered one of the most beautiful boating/sailing regions of the world. Killarney is just at the eastern tip, stunning white mountains line the northern side (Lacloche Mountains) - some geological evidence indicating they were higher than Everest millions of years ago.
The drive around the northern shore of Lake Superior is rugged and absolutely stunning.

Get UA-cam Red 😂
Canada’s Niagara Falls does provide us electricity.😂
With the help of Tesla knowledge
Lived near Lake Erie my whole life. I have seen Lakes Ontario, and Huron. I REALLY want to visit Lake Superior, and Michigan someday. Nothing beats camping on the lakes during a nice summer night.
Thank you I agree with your versions of what might have happened
It seems to me we need to radically raise the temperature of the atmosphere to bring the lakes back to the level they were before humans had an impact on North America. It's the equitable thing to do.
Good name bad idea,lol cheers
“Equitable” is sophomoric joke,…and gullible undergrads and equally misguided professors, along with tenured ‘climatologists’ working the grant industrial complex with spurious algorithms serving corporate/gov’t tax incentives keep the folly current.
@@TheErnie1964 Why a bad idea? It is consistent with the current theme of humanity being evil and restoring Mother Earth to a non-human state. Don't you care about climate change? You must be a science denier. Prolly ultra-MAGA too! A Russian spy?
Workin’ on it!!
@@ernie5229 no I'm a Canadian spy,we have just had the warmest winter on record in Canada so ...
9:05 "it drops it's load" 💦
Very well done. I knew about glaciation ‘&rebounded. But learned a great deal. Thank you!
This was very interesting, Thank You!!
So where is the 5500 cubic miles of moraine material the glacier carved out of the bedrock to create the Great Lakes? This idea makes no sense to me.
This is a conspiracy and YOU bmac5576 discovered it. And surely someone must pay.
16:00 ground into fine particles and flushed into the ocean
If you watch nick zenter one of his most recent interviews with ric baker and skye coolie there are some maps showing where different ice sheets advanced and when you consider the thousands of square miles the glacial till was spread over the material not washed into the sea had lots of room to be spread around
Not nearly that much was actually carved out. the crust was was just pressed down from the weight of the ice. look up post glacial rebound. The great lakes are actually getting shallower as the crust slowly rebounds.
@@thekinginyellow1744exactly. There were chunks of glaciel ice that were separated and the sheer weight depressed the northern United States and most of Canada. The ice melted and made lakes where they lay. Now that the water supply is being reduced it’s taking pressure off the continental plate and it’s slowly rising and they think some of the odd earthquakes are it rising up without the water pressure. Very interesting stuff. The Montana lake flood that gave way is a great example also. Carved out the eastern part of Washington state looks like the Grand Canyon and didn’t take 100’s of thousands of years to make. Relatively quick in geologic terms.
..finally a science/nature doc that doesn't mention climate change rubbish...TY !
You okay?
Yeah, well, I live just north of lake Ontario and in my 65 years have never seen a March like this.
But that aside, the show was not about anthropocentric climate change so ergo it wasn't mentioned.🙄
But go ahead, keep sticking your head in the sand while the world burns and keep complaining when it is pointed out, showing us all just how stupid certain humans can be.
That doesn’t mean it’s not real.
It actually did mention it. You must have fallen asleep by then.
Boo!
I'm not usually into these kind of documentaries, but they kept it interesting. 👌 🧐 📚📚📚
Thank You 👍
Crazy. I love Michigan. The lakes are stunning. Although Lake St Clair is very polluted. Huron is as well. Lake michigan is ASTONISHING! Looks like the ocean. Superior is very ridged. It scares me.
It was aliens. It's always Aliens LUL
Until it isn't
Lake Ontario is the closest to me and it’s breathtaking seeing it. Literally like a mini ocean, you cant even see the other side, it’s crazy
There is also a theory that a comet or asteroid strike in that area wiped out the Clovis culture around that time, and that the object hit the thick ice sheet. The crater was mainly in the ice, and subsequent movement of the ice would have erased the effects on the ground. In addition to the expected adverse effects of such an event on humans in the area, diversion of the drainage patterns would have caused even more problems.
Clovis hahaha no comet it's the sun always proof in abundance but you are not looking for it
Excellent!
Fascinating episode!
End marins were a big part of forming kettle lakes. They are chunks of ice & debris left by retreating glaciers.
I love the field stones left too ☺️
I’m with Dr. Allen West!! Impacting was definitely a huge part of it
An interesting similarity to the Great Lake's drowned forests is in Bermuda where the rising Atlantic Ocean covered cedar groves 7,000 years ago. Cedar stumps and roots have been raised from Bermuda's shallow shelf areas.
Not similar other than both are ice age stories. The tilt of the crust and its resulting rebound were due to the weight of the ice above. The ocean's were approx 400ft below what they are today when all that water was stored on top of Canada etc. When the ice melted, slowly or rapidly, the water filled up the oceans to near what they are today. Lots of evidence this happened very fast, but still not generally accepted.
I didn't know I was going to watch this whole thing. But I am glad I did
In Killarney Provincial Park, the bedrock also has deep grooves from glaciers.

In Peggie's Cove NS Canada you can walk among the large bolders left behind by the ice.
Retreating glaciers carved the grooves in the rock, you can see more of that in areas of the Rocky Mts, and in what is called the Canadian Sheild. They used teach us about this in Cdn schools back in the 1960s and 70s. It was part of the coriculum in Jr, High School (Middle School for the Americans)
I could see my house on your map. Nestled nicely between Erie and Ontario on The Niagara River.
Excellent video. Very interesting and informative. Thank you.
Southern NY and Northern PA are full of boulders dropped by glaciers, some are huge and stacked on top of each other in wild positions, used to camp near and climb them every summer.
I grew up in St. Clair. We have the St. Clair River about 1/2 mile from that house. So my dad had a deep pond dredged in that area. About 14 ft. down. It was real soft gray clay also some fine sand like beach sand. And in the clay were pieces of trees and walnuts, and small shells, especially those shaped like a horn, curly and pointed. Also clam shells. The wood was like new then the sun dried it and it split in 2.
