The Mysteries Of North America's Great Lakes | Naked Science | Spark

The Great Lakes are an incredible natural resource. 1/5th of the world's drinking water are stored in them and they hold enough water to flood continental America 9 feet deep. How did such vast bodies form on Earth? And how are rising water levels affecting these Great Lakes?

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! *edit I returned to Lake Superior for camping and finally found an Agate. The video is on my channel if you’re interested in watching.

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.

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.

[@akeleven]

You could be talking about Seattle or Juneau Alaska.

[@indianastan]

Yes Cherry 🍒🍒🍒 picking season in a few months 😋

[@SamM-gl9zc]

@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.

[@SamM-gl9zc]

@indianastan - Fresh-picked cherries are so good!!!

[@RowanHawkins]

​@@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.

[@peterpiper4619]

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.

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.

[@judd0112]

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

We know how they were formed. No impact involved. If the oceans were forced into these areas there would be proof of it.

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.

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.

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.

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.

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.

[@qman8816]

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.

@richardbonner2354 You heard correctly. There is a locally famous boulder in Central Pak that shows the grooves. I saw it on a ' Hidden places/secrets of NYC/Manhatten' program. I don't recall them being as pronounced as the ones on Kelley's Island. They are more like the ones on nearby Middle Bass Island. We have an erratic sitting near our local reservoir. I believe geologists 'tracked' it from somewhere in central Quebec? The Army Corps of Engineers has an information marker adjacent to it. Also, if interested, another plaque shows how the ice sheets changed the courses of rivers or filled in their valleys. Pittsburgh wouldn't have three rivers if not for the glaciers. The Ohio River (would be another name) would have flowed west and empty into the Mississippi River just north of St. Louis. The dry valley can be traced backed east into Ohio.

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.

[@spuds6423]

Actually, they were diverted because they needed to produce the necessary power.

[@RowanHawkins]

​@@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.

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.

[@Roylamx]

[@PhilipCockram]

The presence of continuous and well-defined northeast-trending lineations that cut across both the Charity Shoal Crater and adjacent bedrock indicates that this landform has been significantly eroded by glacial processes and predates the last glacial advance of the Laurentide Ice Sheet. As the existing research indicates that the rim of this crater is draped by layers of Middle Ordovician limestone, the Charity Shoal Crater must be at least as old as the Middle Ordovician.

Glacier dragging along boulders had to be the culprit. Told my geography teacher, who checked it out himself and agreed with my conclusion. Tonnes of glacial ice sculpted many of the strange formations we find in Ontario. A friend and I found a perfectly round hole about 10 feet deep with a smooth boulder at the bottom. Glaciation again, but too young to have a camera with us to record our find. Amazing ancient formations found by hiking teens in the Boreal Forest! 🇨🇦🖖🏻🇨🇦

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.
