Thanks for the kind words! It's disheartening, especially on top of other waves of tree death like some oaks. All we can do is work on management on our own scaled. Thanks again for watching.

Honestly it's not clearly known and you can find differing opinions. Subduction not really, at least not in the sense of something like Cascadia. More likely some combination of hotspot and rifting, but the exact explanation, to the extent that there is any agreement, is beyond our pay grade. Great question and thanks for the tip!

Thanks for the feedback! Make sure to check out the rest of the series (look for playlist) and other content.

We're grateful for your generosity!

There's so much neat geology everywhere! If you're intrigued by our neck of the woods, you might consider finding the Geology of the Ozarks playlist and start from the beginning to get the proper context.

You're welcome! We appreciate your support.

Glad you're enjoying it!

Lot of good places for that!

We're plenty familiar with the Ouchitas, but their geologic history is distinct from that of the Ozarks so they're not a direct focus for us in this channel. That being said, they will appear from time to time!

Seriously? Noah's flood??? I hope you're being sarcastic ....

@@wesmahan4757 Nope.

Why do religious people always have to inject your "God" into every conversation involving REAL science? (BTW, I was an evangelical missionary in Europe for a decade, but now an unbeliever.)

Obrigado!

You're welcome! Such a great corridor.

Nah just geologic timescales at work.

Thanks so much! We're working through geologic history, so we'll be reaching the sedimentary portion of the Ozarks sometime in early 2025. We have one more pre-sedimentary video to go, and then we need to schedule a major filming trip to move on. In the meantime, you might go back and watch the first few videos of the Geology of the Ozarks series, which do give an overview of geologic time as it relates to the region. There are also a variety of site-specific videos early in the channel that talk about various sedimentary contexts in a local way, at places like Ha Ha Tonka State Park and elsewhere. Apologies for the slow pace of the channel, it just takes time to do these right and we juggle a lot of commitments. Hope you'll stick with us and that your son keeps enjoying learning about geology!

@@ozarkoutsider looking forward to them all. Good stuff, my friend!

Us, too! We're going to be working on a series of FAQ videos as well tackling simpler concepts, so hopefully that's useful as well. Love to hear about kids getting interested in the natural world.

I checked that out on GeoSTRAT, which definitely has an igneous knob mapped just below the dam, poking out through the surrounding sandstone. It would be very cool to see your exposure! Unfortunately we have no near-term plans to be back in that area, as we've done all our filming for the final video before we start covering the broader sedimentary Ozarks. And we're super busy this fall with a lot of commitments. We'll definitely file your offer away for future use, and thanks so much for bringing it up!

I second the NRS boots. I use them all the time all year long in these same rivers.

Thank you for your generous support! Very meaningful.

Thanks for your generosity!

Camping, and fires, are prohibited on Hughes Mt because it's a designated natural area that hosts rare geologic and ecologic features. Unfortunately, we always find evidence of campsites, fires, and worse up there. The lure is understandable but we beg people to respect the site so that everyone can enjoy it unspoiled. The Ozarks are blessed with an abundance of public land where camping IS allowed; there's no excuse for despoiling Hughes.

Music to our ears! This whole channel is about helping all of us appreciate the Ozarks.

I feel really Blessed, I explored many of the same places many years ago and now I get a real geology class on the formations.

Recently I've been searching for plat maps in the Ozarks and I happened upon soil maps for Alabama so if you search you may find the information is put out there by someone so enthusiastic even if they aren't speaking on the subject

LOL, great comment. We visited your area years ago and it was fantastic. I'd love another lifetime so we could do that area justice. The irony of starting this channel is that we've locked ourselves into a lot more Ozark travel but less time to do trips elsewhere!

@@ozarkoutsider What fascinates me about where I live here in Lauderdale County Alabama, which I live right on the Tennessee river. But looking at where the Grenville front was located back when the north American continent was forming. There was a moment where the mid continent rift tried to split. And if I'm not mistaken, flood basalt had been said to have been as far south as to my east. Plus, my area has been under shallow seas several times, also was part of the ancient Ouachita range. It amazes me how there has been so many orogenies that have formed, then eroded, formed again, which were eroded again. And you could go look at where highways have cut through layers of limestone and what I think is called pre granite types of rock. And it seems like rain and time doesn't do a thing to cause erosion. That is when you realize just how miniscule of a moment in time that we are here. It's humbling, fascinating, and extremely mind blowing all in one breath. People that don't understand deep time and how it is reality, and that these processes just cannot form in thousands of years. It takes 100 of millions of years. You know, enough time for us to make a sandwich for a picnic lol! I really appreciate the replies! Yall take care and I'll continue watching.

If you're fascinated by deep time you're going to love the next video in the series, which directly tackles the ~900 million year gap between the volcanics and the sediments in this part of the Ozarks. You might also enjoy the earlier video "Ozarks by era" that summarizes 1.5 billion years of history in 6 minutes! Keep on enjoying your corner of the world, too, it's a neat place I wish we could spend more time exploring.

This is loosely correct; an ancient mountain range, itself deeply eroded from an original thick sequence of volcanic/igneous rock, then buried in sediments that were subsequently re-eroded to form the modern landscape.

Great question; without context, that would be an easy suggestion for why you have igneous rocks poking through sedimentary ones. But there are multiple lines of evidence making it extremely clear that's not the case. (1) The basement igneous rocks date back to 1.3-1.5 billion years ago, whereas the oldest sedimentary rocks are more like 550 million. There are minor examples of later intrusive dikes but these don't affect the broader pattern. (2) Even without dates, the contact between igneous and sedimentary is very clearly depositional everywhere you look; for example, the presence of igneous cobbles in the overlying sediments, clearly derived from the underlying bedrock. And there's no sign of intrusion-related thermal alteration in the sediments (3) Many/most of the igneous rocks in this region are clearly volcanic, e.g. they show signs of having erupted onto the surface rather than intruding underground, so there's no way you could get rocks like that beneath pre-existing sedimentary layers. If you haven't seen the previous video in the series, on the volcanic history of the St. Francois Mts, I strongly suggest you do: it'll clear up a lot of this.

Cool! We like using sites that people can connect to.

Such a great story!

As do your comments!

Thank you so much!

LoL

@@xploration1437 there is proof to the moon there was a great flood. Religious or not.... It is a fact. It happened. So lol... all ya want. Your science has already backed it up

@@xploration1437 historically accurate... Science has proven a great flood.... Lol all ya want bub.

​@@TheLibbyjo but there are great floods all the time. Also a flooding of the known world to the "documenters" as I'm sure you'd consider them, would not neccesarily need to be worldwide to be of that scale to them. I'm not here to argue there haven't been floods, just that a hyperbolic documentation and actuality don't exactly line up.

@@goosenotmaverick1156 there is proof of a global all at once everywhere flood. Long since been proven. Every culture has their own myth story about it. From Mayan's to China. But go ahead with your stab at Christians beliefs. I am talking hard and proven evidence of a global flood.... Long since been confirmed by modern science practices.

Same here (on the second part)!

I too grew up in the current river valley!! Rocks and minerals have been a fascinating thing to me also my whole life!

Dolomites?

Mostly dolomite in the Current River valley but there are isolated sanstones, and of course pockets of igneous rock as we showed here.

@ozarkoutsider those granites are the closest Precambrian rocks to Lawrence Kansas. Ig-Met Pet field trip!

Buford is sneakingly tiring, but well worth it! We've always wanted to camp up there overnight to get that amazing view combined with stargazing, but haven't made it happen. Glad this video helped you appreciate the bedrock.

@@ozarkoutsidersame! Overnight on the summit is still on my to do list!

Happy to help maintain the connection! Hope you can keep making it back now and then.

It's a really neat resource!

You sound like you'd do great in either of the Missouri settings! Jeff City is a great base for exploring the entire 240 mile Katy Trail, but in the Springfield area you should also check out the Frisco Highline Trail, a 35 mile rail trail that runs north from the city. ozarkgreenways.org/explore/greenway-trails/frisco-highline-trail/
