Great video. When I was younger, I use to hunt in those mountains in mid-state Pennsylvania. You can feel that the place is ancient. One memory I have that stands out to me is that it can be so quiet there you can hear the snow fall.

You deserve more views and subscribers.

The Apps fascinate me, considering their great age. I grew up in NH with the White Mountains, a part of the Appalachians. I'm in my early 60s and living in Missouri, so I doubt I'll ever hike the Appalachian Trail but I'd sure love to!

the surface of the planet started making more sense... when i began to view the whole thing like a brain... thus caves are access points into the different homunculi of an over-mind... in which that region/area correlates to the higher function of planetary and cosmological consciousness...

Glad you posted this. How do you age the different mountain building events?

I can’t “like” this video as much as I want to. I live in and am amazed by the Appalachians. Everytime I see twisted and layered rock formations, my mind is blown by how it got that way. Thank you for your in depth and illustrated explanation.

Thank you for the presentation. When I originally took a geology course back in 1962, none of this was known. I was taught the major movement was up and down not lateral. As I continues on for my graduate studies in the university of Alaska, I was dealing with professors who could not conceive of the history of Alaska. As I mapped the basalts of central Alaska they looked more and more like oceanic basalts. My professors were in another world, it was now the 1966-8 period when the revolution really started to hit the world of geology. They would not allow me to put into my thesis the reality of what I saw. So my thesis on the basalts of central Alaska had nothing of the reality we now know is true, Alaska is made up of many portions of the island arches that collided with the Rocky Mountains (known as the Brooks Range). How far we have come. The rocks always tell the truth, never ignore what they are telling you! For my Ph.D I did high pressure temperature research for one reason, I could not stand the political environment of the geology profession at that time!

Please clear ur throat and figure out how ur maps are working then film.

Learning that the Appalachian Mountains aren't done cooking yet has just set my hyperfixation into overdrive lol.

Very nice job. Thanks 😊

Hello, it's so good to see another person making fossil videos. I would like to share my series of videos with you. They are old and grainy from before the time of HD videos. Years ago I collected 100 trilobites a 3-minute drive from NKU. Each trilobite took on average 45 minutes to find. They were found in a field across from the cable radio station on Johns Hilltop Rd. Sadly they have dumped topsoil and grass seed on the rocky field to try to sell the land. Its no longer good to collect there it covered in soil/ grass now. It was called the Coryville formation known for trilobites. You can see my trilobites in this video series of 24. The playlist is on the right . My fossil club the Dry Dredgers has monthly lectures avaible in person and zoom. They also have monthly field trips. My name is Greg Courtney, it's nice to meet you . Come join us for a fossil hunt ? th-cam.com/video/j_sdu17a1go/w-d-xo.html

Will the Appalachians mountains get any taller in the future

Ive become obsessed with PA geography (I'm from SW Ohio) and what is driving me crazy is that the Alleghenies are part of the Appalachian Plateau but then other stuff lists them as part of the Ridge and Valley province

I live in Allegheny county Pennsylvania and the hill I live on is topped with Monongahela formation Pittsburgh Coal bed and at the base of the hills is Glenshaw formation Pittsburgh RedBed with Ames limestone lining the valley til I go a mile east the the Casselman tops the hills with Glenshaw halfway down 😮 the geological survey the museum did when I found Batrachichnus foot prints in Duquesne sandstone or the very top of the Grafton sandstone. What was confusing is there’s a red bed and freshwater black shale the splits the Duquesne from other Birmingham shale. However there’s also red bed mixed on top of the Ames Limestone mixed throughout the Grafton sandstone with some fresh water limestone in the Grafton horizon. The museum people did say geography is extremely complex and even within a horizon there will be a ton of different environments within. Keep in mind that you can go a mile from a location to another outcrop of the same horizon but it could be a completely different environment that’s the same age 😮

Very interesting video, thanks for sharing.

Great video!

The way subduction zones arise at the margin of a continent is not so because the oceanic crust is old dense and sink. It is denser than continental crust and the oceanic crust is literally thrusted under the continent margin by Earth thermal motor that create giant convection cells. The oceanic slab (3.0 g/c3) do not fall into the mantle (3,6 g/c3) because it is less dense than the mantle. It is thrusted forcefully into the mantle by the convection of the underneath mantle.

3:15 Norway is a basin? What?

If you have any further info on the piedmont, point me in that direction

I live in Feasterville Trevose Pennsylvania where the Atlantic coastal plain meets the Piedmont . These ancient rolling foothills are very much part of me .

I grew up in the Blue Ridge and have lived in the Allegheny. As a kid I loved finding sea shells and fossils in shale outcrops and creaks. And one winter we had two to three feet of snow in the upper mountains. And then one day had temperatures in the 70's. When the floods resided we had several feet of rocks in a small mountain river with some large boulders. And it was easy to sea how mountains that were once as great as the Himalayans have eroded to what we see today.

Thanks. And then there is the supposedly debunked 'Electric Universe' model which I subscribe to. Really! What's the results of the near catastrophe collisions of planet Earth and planet Mars? Massive geological changes to both in short order. View the Southwest USA and Grand Canyon on Google Earth from about 40 and more miles altitude. Striking features.

Odd how you didnt mention how the appalacians were basically knocked on their side showing vertcal layers, whick can be seen openly at seneca.

I went to elope in Asheville, told my husband about how the Appalachians were formed. HAD to find a video on it, started this one and said “oh hey, that’s Julie Reizner!” I took your class around 2014/2015 at NKU. You are a great educator!

It's awesome seeing how this planet works.

Thank you for the excellent explanation about the Appalachian Mountains. I especially liked the very informative graphics. As a result of your video, I finally have an understanding of the Grenville Orogeny and its significance. All of us have grown up in a seemingly static world, but this video very neatly demonstrates the changes over time. The asides to Brandy, the dog, however, were major distractions that interrupted the continuity of the flow of information and disrupted learning. I like dogs and am sure that Brandy is a fine dog, but including Brandy was totally unnecessary.

BS

Could you have not written down and rehearsed this entire talk in advance? Too painful to finish.

I really enjoyed this lecture. Geology is so interesting and the Appalachians in particular. Thank you.

A very disorganized presentation. "All over the map," as the saying goes.

Humans not long on earth..geology not studied not very long..

I live in Southern west Virginia in the Allegheny mountains which are part of the appalachian mountains

Thank you, very interesting. Could the sea level drop correspond to a cooling climate and increased polar Ice caps?

Very interesting and in formative. Thank You

Smith Rock in Oregon is tuff from a very old Yellowstone eruption.... it's rotated and translated north and east. Many geologists believe that the Large Igneous Province that became the oceanic plateau/island Siletzia, which collided with North America about 53 million years ago, and then translated north to become the coastal mtns. from Olympic Peninsula down to about Coos Bay, was formed over the Yellowstone Hot Spot when it was under the Farallon Plate.

It's crazy that mfs think the earth is only a couple thousand years old.

Thanks for this fine video. Lots of good information. For future reference: Is there a way to present the slides so the text is not cut off by the small window of the lecturer? Anyway, excellent video and I hope to see more.

Pronounce it apple-atcha or I’ll throw an apple atcha! ;-)

Folds of skin/flesh are gills. gotcha.

Good review of concepts with which I’ve grown up through shelves of books, specimens and some field work in the neotropics . My middle name is Darwin and my childhood heroes Humboldt, Wallace, Bates, and Wm. Beebe as well. Education in the history of science and those doing the fieldwork key to understanding concepts. Nice to find your straightforward lectures. Keep going.

I’m definitely not in your class, but I really enjoy the way you present the material and touch on things connected to the subject matter… I started with a video about the Appalachian mountains while driving through them, curious when or more importantly HOW they formed, and found your content… I’m a huge fan now! I bet I’ve watched 10 different videos completely in only a few days. Informative, educational, I assume they’re for studying geologists, but I’m hooked. Thanks 🙏🏻🙏🏻🙏🏻

Another question, Before life contributed to the ocean floor, then were volcanoes granitic volcanos different due to less calcium and carbon?

So if the outer core is liquid, then why is the mantle thicker and more viscose?

Ok so the magma starts out basalt, but it gains silica as it makes it's way upward. ?

Thank you very much for this lecture. Reminds me of my college days (I miss college).: So we have continental collision, subduction, subduction, and again continental collision. Are there other ranges with this much complexity?

This is fantastic. I watched this for fun

which "story of the earth" book are you referring too? I would be interested in reading it, but have found multiple with the same title. Thanks!

Pronouncing Appalachian wrong lol

Hello, great presentation. How do you account for Planetary Collision Dynamics from subsequent impacts by XL-Asteroids and Active/Impact-phase Comets? Comets atomize H/O/C/N/elementals/rock/etc. then may smash into Earth at Mach >30. Newton's, Gay-Lussac & Thermodynamic Laws will apply. 🤔🖖🏽♻

Quetzalcoatl is the Appalacians
