    Also IIRC a lot of the pacific coast mountains around the world are from the same volcanic activities caused by the Ring of Fire

    The most amazing part of this is that Florida is shown to be a part of the Appalachian Mountains. Meanwhile, its highest point is only 345 feet (105 meters), which is the lowest state high point of all 50 states.

    Way back when in the brontosauria two very fat brontosauree started fighting each other. They went up the mountain for privacy and one was on top of the other and then thr other way around. What a fight! What passion. They broke back the mountain. That's why real brontosaurus are found in water. LOL I know their name isn't brontosaurus! One was Uuuhoohuuumpfffshhhthuuuu. The other went by George, but we can't corrpbolate that encabrulator.

    I knew about the Appalachian and Scottish highland connection, but I did not realize the chain extends all the way into Greenland and Scandinavia! Per my quick Google search, it says there are remnants of the same mountain chain in 9 countries!

    I knew the Appalachians were so old they'd worn down to unremarkable peaks, but I still hadn't considered they were tectonically old.

    The Appalachians have had 3 orogenic (mountain building) periods followed by significant erosion. What you see currently is the result of the last erosional period. Imagine something much closer to the Himalayas (similar continental convergence process) at their highest. Appalachian geology is rather complex compared to other mountain ranges. The Rockies aren't quite comparable since they formed due to eastward migration of a shallow angle subducting plate. Trust me, I'm a geologist.

    Still pretty remarkable, just that they were so much bigger before. The wild thing is learning that most of the land east of them to the coast is sediment from their erosion. It makes sense once you think about it, but imagine the amount of time to do that.

    This is really interesting. The Ouachita Mts are also listed in the article and they are a really pretty part of the world to stop in if you are in southeastern Oklahoma
