Please look into Mudfossils university here on KZbin. I work with a plethora of different chemicals for work in a machine shop and must know which can’t be mixed or in series. Geology is biology. Leviathans are real. Oil is blood water is digestion waste and those sinkholes/mudpots with rotten eggs smell is solid waste. Digestive enzymes(or mucus) and bacteria are found in all and they fix the matter to be better at chemically settling. Thanks for your time.

Grrrrrrr. The Crater Theory, due to climate changed was debunked the same day it was discovered. these are called Thermokarst's and they show up in permafrost everywhere. No explosions, no Methane just plain old frost heave and subsidence over a period of time with the the spring thaw and winter freeze. In warmer climates we call them pot holes. A large portion of Canada's northern lakes are in-fact Thermokarst's that have flooded.

Shortly after visiting the Mima Mounds, I was operating a heavy piece of machinery with a thick steel plate drilling deck. This deck was covered with a about an half inch layer of dust. When the down hole bit contacted an irregularity, there was about 3 or 4 very strong vibrations in less than 2 seconds. These vibrations piled up the dust in neat little mounds that had the same pattern as the ones I saw. Earthquake?

[@johngalt97]

Some researcher figured this out decades ago after seeing sawdust mound up around a jigsaw.

[@haroldwilkes6608]

Exactly. Washington state is ripe with volcanic activity. Now I just want to know if the other places that have these mounds are also volcanic?

[@MsSwitchblade13]

That's a really neat observation and comparison. I was actually picturing it as you were explaining it and it made sense in my head. Thanks Sir Bambeur for teaching me one more thing today even if it's was just about dust and it's formation under vibrations. :)

[@craigparse1439]

Firstly, I'm not a geologist. I live close to the Mima mounds area and I know that that area of the state has lots of glacial drift from the forward edge of ice age glacial sheets. We are also not a stranger to earthquakes. The working theories of fluid dynamics or tectonic activity seem likely. We also have LOTS of gophers although the one that was pictured is a protected species at this time.

[@Mostly_Harmless99]

Suggestion for another episode on geology weirdness: 1) There is the Baja-BC controversy which posits that much of Western WA and Vancouver Island started out 200Mya in Baja California and through the miracle of plate tectonics and rifting of Rodinia that shuffled the current continents’ locations. 2) The ‘slow slip’ phenomena around the Cascadia Subduction Zone in which most of Oregon, Washington and N Cal is rotating around Pendleton OR at 4mm/year, except every 15 months when it reverses.

I have recently just finished taking a geography course at my university and the mima mounds (5) are similar to the patterns we studied. Patterns like COULD be caused by freezing and thawing events, as when freezing happens it expands the material and then settles when it thaws. Moving the material, not sure why the patterns occur but it could provide an explanation other than burrowing animals.

I grew up near the Mima Mounds. In fact, some of the mounds were on my fathers farm at there northern end. The area is the southern most extreme of the Olympic Peninsula. It is glacial till up to forty feet deep sitting on a plate of basalt. There is a mirror prairie, on the other side of the valley, 10 miles to the east just north of the town of Tenino WA where the mounds are also evident. The best explanation that I have ever seen for these mounds was when a geologist laid a sheet of plywood on a pair of sawhorses and covered it with sand. He proceeded to smack the plywood with a hammer. the sand sorted itself out into mounds on the plywood. These are called resonant nodes and anyone can do this do this simple experiment. In the case of the geology of the area, the basalt plate is like the plywood and the glacial till is like the sand. The hammer is the subduction earthquakes that the area is subject to every 3 to 6 hundred years which liquefies the till.

One frustrating aspect about these mounds is that many of the theories would have the same end effects. It's entirely possible (actually probable) that the features we label as Mima Mounds actually represent several different geological types of terrain, but they all look almost identical. So what formed THE Mima Mounds outside of Olympia WA may not be the same thing that formed all of them around the planet.

[@NouriaDiallo]

@@zacharymoran7596 yes, for example, similarly shaped (but smaller) mounds can be found in French Guyana.

Until I realized it’s sheer size, I thought that picture of the Nastapoka Arc was the result of one of those mesmerizing ice disks that sometimes form along slow moving rivers. Basically a sheet of ice above a bend in the river will break off and float on the surface, but the surrounding ice and currents don’t allow it to drift away. So what can sometimes happen instead is that it will begin moving back and forth from the force of the water moving past it, gradually grinding and refreezing until it finds the path of least resistance and turns into a perfectly round disk of ice that rotates with the current. The whole thing looks like someone took a saw and cut it out of the ice around it.

I think numbers 5 and 6 could be related. like if you had sand on a hard surface above a speaker and played noises to make shapes. im sure magnetic field has something to do with it too

5. with the Mounds. Large trees that were felled naturally will do that to the land. In NE they have those kind of mounds in the forests. Ancient old trees covered up with sediment and other leaves that over time continue to slowly, slowly, slowly rot away. once they do, all that weight on top pushes down and displaces underweight. Im talking Big trees.

[@kiddlorenz7582]

It literally reminds me of The Chocolate Hills in the Philippines but much bigger

[@phishENchimps]

@@kiddlorenz7582 friends sent me pics when they traveled there. so freaking beautiful. he had a drone as well. the video was amazing. It's the grass that holds the mounds, hills together. roots of grass go straight down. trees spread out and rip up and out. Grass can actually be better to maintain a hillside than any amount of trees. simply because of the root structure and the ability to hold the soil in place. probably why the chocolate hills stay the way they are, that and a Hurricane every few years that would destroy any tree growth that high in elevation..... But the grass holds the hill and won't get blow away.

I live very close to the Mima Mounds, in Washington State, USA. I can confirm that big trees are common in Washington. I have a table one meter in diameter I made by cutting a single disk off a 1 meter diameter log -- and this is quite small by historic standards. A hundred an fifty years ago before industrial logging, 2 m diameter trees would not have been uncommon. But, while large trees once covered almost all of the western half of the state, the Mima Mounds are limited to a very small area. If it was tree related, I would expect the mounds to be more wide spread.

[@phishENchimps]

@@andrewsnow7386 really might depends on soil quality. where Ive live, in places where it's happened naturally (woods) and seen a place where it happened because of man. a golf course. when they built the golf course, they cut down trees. instead of clearing the trees, the builders simply built over where they fell. they placed yards of soil on top. course was set and decades latter they noticed slumping in the turf. every year it seemed to get worse. The slumps and ruts came from the rotting trees underneath giving weight to the soil above. there are many other natural causes that could lead to this that are all interwoven. like.. once a small mound has begun, grasses will take root. seeds, acorns, seed nuts, fallen fruit will tend to travel downhill. especially if there is water present. washed away. only thing left is grass. Nature is dynamic. I can at least tell you that the mounds in the NE forests are at least caused by Trees that have fallen. and the things that happen after. the trees falling are just one part. soil, water, elevation. With Natural effects, everything is interwoven, unlike the dimorphism of human sexuality.

This is one of my favorite episodes, very cool

3:36, I was just looking at Ile René-Lavasseur a couple days ago because I thought it looked weird and was also trying to find different layered island formations. Really cool area with many peat-colored lakes and rivers around it.

[@christopheb9221]

how big are these impossible rocks? like the island is made of it or just a bunch of rocks on the surface?

I'm surprised the "underground mountains" weren't mentioned. Some scientists were doing scans of seismic graphs n found sort of upside down mountain ranges beneath the Earth's crust. They called it the transition zone I believe

[@KOKOBC]

Sounds pretty far fetched but it does kind of make more sense the more I think about it.

[@Zappygunshot]

It's not too difficult to imagine how that would form. As plates smash into each other and fold and bunch up, you get areas where the plates are thicker than in other places. Much like how a taller boat has a deeper keel, you'd see a vaguely symmetrical mountain range form on the underside of a plate as on top

[@tempestive1]

I learned about this in ecology a few years back, except I was presented with an explanation described as more definitive :o Basically what was mentioned, OM from turf accumulated over centuries, and how there are identified massive pockets of methane which would release into the atmosphere if this permafrost melts, further contributing to global warming. Guess its time to refresh on that haha

[@johannessordfarne4553]

Very good presentation - as always. Complicated topics made clear and managebel even for us without higher education in sciency-chemistry-physicsy-math-ish things. Thank You.

Those mounds being everywhere other than Antarctica just made me think they were man made lol.

[@sophierobinson2738]

Antarctica is covered with snow and ice. Can we be sure there aren't little mounds hiding underneath?🤔

[@vdbcorten8697]

That's what I was thinking, in archaeology these sort of formations are usually found as a form of burial (although usually more spread out and less consistent) . It might be interesting to see the results of an archaeological research

[@zbatchDOC]

The amount of time I’ve spent on KZbin and I still find channels with millions of subs that I’ve never seen… this astonishes me.

I believe the Mima mounds mystery is solved. There are new ones forming now in siberia, and its happening quickly. Permafrost is melting, and previously flat areas now look just like Mima mounds.

[@zzzubmno2755]

I enjoyed this vid. thanks for making it. i do think a lot of mysteries will be solved soon enough, but not as soon as the curious would like it. there is no money to solve these mysteries and it cost lots of money to study them with very little return. Hudson bay has always interest me. i am one who believes it is an impact creator, but one of the oldest in the world and possibly an event that was so destructive that it cause a supercontinent of the time to break up. Hudson bay and the Hudson bay lowlands is something i wish was studied a lot more. those holes in russia, meh, not too hard to explain if you ask me. i think it has to do with the stratum of the area forcing pockets of gas to build up in areas, almost like the formation of pingos, but instead of water, it is natural gases, perhaps a combo of the two forming at once, but instead of a mound, it explodes with pressure. those gopher hole things, that's interesting, but again, also easy to solve with cores. at first glance, they look like moraine deposits. areas that experienced fast retrieving glaciers deposit mounds that look like a fleet of dump trumps that dumped a bunch of mounds of debris. I would need to look at soil and core samples of the area. there are several things that could be causing those mounds. the Madagascar quarts things is interesting, but not to hard to explain. could be as simple of volcanic fishers that formed under a massive sand bar and the heat met morphed the above strata into quarts. deep core samples of a large area would help. as for areas that are low in gravity, there is many and explainable reasons for that. people need to learn, this planet was not made in a few days with one day of rest. it is billions of years old and has experienced many epochs and eons of change. from poll to poll, this planet has been covered with miles of ice. snow ball earth isn't a myth, it happened and more than once in our planet's history. glaciation has changed this planet in many many ways, and many times in its history. glaciation does explain a lot the events in this vid, Hudson bay is a prime example. you only need to visit Sudbury Ontario to see movement of of multiple continental glaciers that spread throughout the North American continent from the Hudson bay area. Hudson bay was scoured many times throughout this planets history. The creator that was, was made greater not just by glaciation, but also from tectonic movements. any whoo, im rambling. thanks for the vid, it was interesting and gave my brain a treat.
