Having spent over 35 years walking those rivers and trails I can’t believe all the rock exposed. I absolutely love these videos as an amateur geologist, thank you for these. I found you right after the hurricane when you posted your first video, really great work.
@@TheGeoModels There is a boat upside down in the Cullasaja River near the Macon County middle school. I can't drive the mountain roads much any more, so I appreciate you doing all the work!!
@@TheGeoModels I haven't been climbing or kayaking out there since I was a kid growing up in NC. I've been working with Indigenous women of the Southwest and Mexico since 1992, and watching this unfold for friends and family in NC is really clarifying both the humbleness, and the wisdom, of the various Nations who have been displaced by US expansion. Especially when you got to the point of the house swept off it's foundation "in the valley" The Tsalagi of NC taught me to never set up camp in the valleys of NC mountains.... and in the Southwest, we're taught the same: Never camp or build a home in the valley. Hurricane Helene has taught us why, and reminded me to ignore the original people and the stories that begin "since time immemorial" at our own peril. As horrible as the loss of life was, looking at the satellite imagery....it could have been so much worse.....
Your videos are very, very informative. Question: I see only young trees...10, 20, some 30 years old, but few. When was this logged out? Would more old growth have helped to prevent this?
The massive flood has revealed and created a rugged beauty in the landscape. You can literally see layers of time. Thank you so very, very much for your quality work. It is much appreciated by many people.
OMG! You actually zoomed over my sister's house on Oletta! She lives where the small stream meets the Tumblebug! I was up there two days later to help her save what we could from her house. She had a foot of flooding in the house and at least two feet of sand and mud in the yard. I'll be happy to send you some pictures. The creek completely changed course in places, as did the Tumblebug.
I live off the Big Hungry Road. I've been walking my dog upstream of the dam for years. Its was her favorite spot pre-Helene because the river was usually 3-6in deep and sand! Easy on her paws and amazing tennis ball fetching. I took some pictures of the dam during the event on both Thursday and Friday. I had to army crawl to the top of the dam where you were filming on that Friday. We've been down there since the storm and it is amazing how different it feels. Thank you for posting this video. I am passionate about this place and appreciate the knowledge.
@@TheGeoModelsseems most of the reporting, at least by Mainstream Media was in and around Ashville, as it was much easier access. For that reason most of the World will never know the effects of the storm all over the Souther Appalachians. That why your Videos, are so important, and much Appreciated !
That stuff is on point. I got to do a thing on rock movement in Chimney Rock/Rocky Broad with it. They just flew us new lidar out in Big Hungry/Green/Rocky Broad, so keen to see what that looks like. You can see one rapid on Rocky Broad that had a HUGE boulder get flushed out of it. Imagery will keep me busy til folks such as yourself start posting up the best LP shots next spring
I enjoy the views and the analysis. If I was back in college, I would have been exhilarated to be with you. Alas, I’m 75 and college is long gone. Fascinating!
@@TheGeoModels i’m only 82 and I’ve seen this video of Phil walking across the log while holding a GoPro . I can only say that in my prime, I could’ve taken him to places where he’d be trembling, like a dog shitting razors.😝😝 But thanks buddy I love your videos !
Wow the scale of this flood is mind blowing! Thank you bring us this up close look at the flood of Helene! I am sure the people living in NC never imagined this could happen .
I got excited when i saw this video get posted while watching another one of your videos! Another level of education getting to see the human scale and perspective of a cataclysmic event.
All of these rivers post Helene look super clean as if they were sandblasted by the bed load and the suspended load of the rivers. Truly a massive cleaning out and I am seeing lots of channel migration and relocation. Keep up the good work with your videos. Great information for so many.
Little over a hundred years ago, my step family came to the Ozark foothills of Missouri. They knew back then not to build near water unless you had a very high bank with a low bank across from it with room for the water to spread out. I am amazed by the people who built in some of these places rather than higher ground. When you have this set up you farm/garden the creek banks but never put a home there. Maybe an animal shed but you expect to lose it every so often so real basic. My grandfather said that if it was bound on both sides go at least twice as high as the highest historic level by the memory of oldest folks around. He built his homestead on a high bank that was forty feet above the creek with hundreds of acres across from it to flood. Of course he had nearly a thousand acres to choose from. Last time I was down that way the homestead house was still there. And yet in the mountains a landslide can get you even if you are on high ground. Roll of the dice I guess.
A lot of people were well out of the 1000 year flood plain and still had their homes destroyed. Forty feet above the creek like your grandfather built wouldn't have necessarily saved his home in an event like this. It's been frustrating to hear people not from here saying folks shouldn't have built in the flood plain... they didn't and their homes were still destroyed by flooding or debris flows.
This is my absolute favorite YT channel. Having my husband watch geology videos w me used to be the equivalent of him dragging me along to Guitar Center...but your channel is so interesting that he's now a subscriber, too. So thank you, genuinely, for the hard work and time it takes you to make these videos.
@TheGeoModels I spent the day at wilson creek today. I live between wilson creek and Linville and there are definitely changes to both. I want to check out Harper's Creek too. At the confluence of Harper's and wilson, a bridge was damaged, so I image the flow was significant
I couldn’t even recognize where you were. Unbelievable. Great video again and I really you hope you continue to do these “from the field” style videos even after your coverage of Helene aftermath ends!
there are so many of these places I’ve spent so much time and I’m a little scared to go back. Thanks again for the videos man, it’s really been a good way for me and I would imagine a lot of other people to process what happened a little better. Cheers!
This is the video talk I've been waiting to see. I've been so curious what the scoured steamed beds and gorges look like post flooding. Amazing power of water! I'm impressed with the way you rock hop and scamper over cliff faces. I'm happy now to take the vicarious hike with you behind the camera and commenting as you go along. The maps were great too to visualize the pre and post views. Very interesting!
I heard my Mom and Dad and cousins talk about these places such as Pensacola but until I watched your videos I did not realize just how close some of these places were to the ones I knew (born in NC and went back to familiar stomping grounds at least yearly), but seeing your videos and maps made me realize some of them were just over the mountain from those I was familiar with. Thanks much for the Lidar and the hiked videos. I think I will wait a bit before attempting an in-person visit 😢; meanwhile prayers and as much support as possible for my Carolina cousins. Thank you for your excellent and informative videos without which I might have been hesitant to venture back later into those little hollers where my ancestors rest, truly some places I wondered how they ever found.
Exceptional. This landscape architect can't get enough! Sorry for the loss of so many family homes, businesses and lives Thank you for these valuable lessons, as they must be recored, remembered, and applied.
How that water cut through that bedrock is incredible. I heard one community member state “it sounded like a freight train”…it must of been terrifying. No wonder people are missing..I pray for them and their families ✝️
well it cut the bedrock over a great period of time, but it certainly knocked a few chunks out this time around. desk sized boulders would have been tumbling down that little gorge. I bet you could feel it rumbling if you were close
14:53 I most certainly saw a major change in river color and density during the big surge arrival in the Green River Cove by the Upper Bridge across the Green. The odder even changed and trees got pushed over quickly and the "liquid landslide" scoured the lower cove. That sediment may not have been water but that mud still have volume and it definitely added to the surge displacing more water. It also increased the density and impact. I watched this unfold with my own eyes from the porch of the Green River Ranch across from my property just below that bridge I mentioned. Thank you some much for sharing this video and your insight Philip Prince. I owe ya a few beers when I ma back in the area,
Most of my work is focused on western NC, and comprehending Helene's short- and long-term impacts requires folks such as you. Thank you for sharing your insightful and compassionate dedication to your craft with all of us.
Yes, it will contribute to geologic understanding, particularly in terms of landscape history in the Appalachians. Many deposits of stored sediment have been laid bare, so folks can see how old they are now and figure out how long the landscape has looked like it does, etc. etc.
These are such great videos to educate what happened in all of these different places during Helene. So many trickles became big streams and streams became raging rivers and rivers well there isn't a description of what they became. As I said before, our stream or creek was about 15 ft across. Had flooded many times. That day it was about 100 ft across. I've never seen anything like it and hope not to again. I still stress when it rains and we were one of the lucky ones. Even our creek, which is an extension of the elk river, has stones and boulders everywhere and trees laid down all along it. Please continue educating us on this. It's horrifying and yet interesting and informative at the same time!! I'm also tickled Brad Panovich discovered you!! He is the reason I was so prepared in Avery County the day of the storm. He kept saying I'm really worried about our friends in the mountains. I thought ok let's prepare!!
I live just a few miles from here and it’s really incredible to see how clean the river is no dirt no moss or anything. I’ve never seen anything like it!
I just wanted to thank you for all the informative videos, you have definitely helped me to understand what exactly happened in that area. My heart breaks for everyone affected by Helene!
Your records are a treasure for so very many vocations forever! Kudos for your efforts - wish we could nominate all of you reporting this history for a significant award!
We have property on Citico Creek in TN and it floods about once a year. It doesn't get too far out of the creekbed but the size of the rocks and small boulders moved by the force of the water is mindblowing. And frightening to think about the consequences had Helene's course been slightly different.
I am used to hopping rocks in the Appalachians, so I know what ya mean lol Really enjoying these videos on the geomorphic impacts of Helene. Hope you feel better soon!
Yeah I'm squared away---thanks! it's funny to move through there with such ease. The friction on the rocks is great. It reminds me of some gorges in Jamaica that get floods like this annually.
Fascinating video. We live in that subdivision where the bridge got washed away. Thanks for sharing the story of what happened down here on the Big Hungry River. Our house has gullies on either side of it, both with seasonal streams. But they both turned into torrents during the storm, with 14 debris flows that broke loose. We kept hearing trees fall followed by what sounded like a large truck driving on a gravel road. The flows took out a large chunk of road and our neighbors' septic field and pond, but the houses were spared. The video shows a house that was hit by a landslide. There was another place just to the west of it, essentially a fifth wheel camper set up like a home. The frame of it is now in the river about half a mile downstream. There was another couple that live just upstream from the landslide-hit house. They sheltered in their attic, and could reach down and touch the water going by. Thankfully their place stood. If you do come back to shoot more video of the river, I would be happy to show you some of the areas in the subdivision that might be hard to access without an escort.
I'd take you up on that. Interesting to hear some of the folks' stories. I wanted to be sure I did this video because of the scale of the impacts in there and the fact I didn't ever hear about it anywhere. The area was absolutely flooded as intensely as anywhere else. It's hard for me to visualize what it would have looked there where Tumblebug comes in. There's an email at the link below--drop me a line! princegeology.com/about-philip-prince/
Gracious me! Fear is definitely not created equal. Being able to feel the creek water flow just by reaching my hands down while I'm sitting inside my attic has got to be fear on the edge of insanity. Merely trying to comprehend such an acute upside downing of everything around is what nightmares of the worst kind are made of. Much love and warmth to you and those you love!
Excellent presentation. Thank you. Looking forward to the boulder movement video. I have often wondered how they got where they were and their subsequent movements. What a great opportunity to study that.
This channel has helped me make sense of what happened all across the area. I live in Avery County N.C. on Birchfield Creek which runs into the North Toe River right below the Minneapolis community. We have never seen so much exposed bedrock and river beds. Area's that use to be acres and acres of beautiful river side properties area just GONE!! It's unbelievable how much dirty was moved.
There was a geologist working in the 40's - 60's named Luna Leopold who showed, for the fist time I think, that contrary to popular opinion, streams and rivers do little or no erosion to their beds day and day out. It's only in those brief times when a large flood comes through where the entire bed of the stream system gets lifted and churned into the flow, and large cobbles and boulders begin moving and bouncing down stream that the channel gets eroded. It has probably been thousands or even tens of thousands of years since those Appalachian streams have experienced flows on that scale.
Probably true. Flood energy is not a linear thing, in the sense that a flood "twice as big" would have many more times more energy associated with it. Things definitely got a good shake this time around. It would be interesting to know how floods looked during the Pleistocene. They might have regularly been even bigger!
the notion that low flow streams carved out bedrock is just pure nonsense; The New River was considerably higher in the past; as a contractor/landscaper/equipment operator, I've dug around all over the place around the river, and in many places I've dug into smooth river stones and boulders layered 6-10ft thick in veins (some the size of cars), 150-200ft above the current river levels. And this is in Ashe Co., near the head of the river. These mountains and valleys weren't carved out by a little water over a long period of time, they were carved out by a lot of water over a relatively short amount of time
Looks like the Andes too! I plan to visit Cove Creek and Little Cove Creek when I return stateside. Thank you for sharing this. I witnessed the flood downstream in the Green River Cove.
Thank you for recording this information and these places for their historic value as well as scientific value! I am sure others viewing this will see more information in them than you imagined! Great work!
After the Ivan flood, the national park service had the opportunity to mark the high water point on the trees around their parking lot at Linville Falls. Those cars would’ve been about 8 to 10 feet underwater. This flood drives that flood out of memory But it would’ve been nice if those who visit the area Goode at least had an idea of what that river could do !! Another hundred years and we will forget that there was ever a flood in Asheville or Black Mountain or chimney rock…. Unless people preserve the record.
This is so interesting. I noticed on some of your other videos that the rocks walls looked like a thrust had happened long long ago. As tragic as this event was there has been so much info in your field. Thanks for all of the information. I'm learning a lot.
Thanks for showing the befores and afters of the devastation from Helene. I appreciate your work and your videos also provide a distraction from the other news of the day.
Wow, just finished watching, thanks for the field trip, and the wrapup with the great overview. I'm looking forward to your investigation of how far those huge boulders moved during the flooding. The power of water is amazing, your videos are helping me visualize geologic timescales of mountain removal! I hope you are feeling better, btw.
One of the small creeks in Boone, NC had a distinct blue/green tint to it after the initial sediment settled out. Much like glacier fed creeks I have seen elsewhere. My guess is that the grinding action of the rocks created a larger of dissolved minerals than usual. Very interesting.
I'm addicted to your videos. Love the Appalachians, and amazed by what happened up there. Your videos have explained it in ways that make sense (well, sort of...) and spark intrigue. On a side note, I found some really good imagery with soar.earth as well. Really high resolution, and... Layers 😁
Wonderful video!! From what I've read on the great Connecticut floods of 1955, it was also the very small (many of them usually dry) tributaries that did the bulk of the damage there, too. This resulted in the entire state being declared a major disaster area.
Thank you for sharing your experience. As a biologist and a native to the mountains, my heart is crushed by the destruction of habitat-for plant, animals and people😢
Remembering the geological history of the Scour Lands up in the NW area of the USA, and the Mt. St. Helen debris flows = your videos show a much smaller scale of what Hurricane Helene did to this particular Appalachian river system. Just think! To us mere mortals, your videos are amazing to see the scale of human beings to this! Folks, this is the power of geological forces on our planet, impacted by weather and climate change events! Thank you, Philip, for sharing your knowledge and study area with us!
I live in a very tiny, remote community way back in the Appalachians. My creek is usually 6 inches deep and maybe 3ft wide. That creek swelled into 100ft wide and ranging from 2ft to 10ft deep. Never in my life have I seen that. The entire streambed is changed. It doesn't flow the same.
From what I have seen and heard, that was sort of what this storm did where it hit hard. the funny thing is that if you go west of the hard-hit area, things taper off quick and it's business as usual. if you got under one of the intense bands on Friday morning, though, different story...
Thank you so much. Is there anything remaining of the other dam on the river? I don't know if it was removed before the storm, I only remember it being debated years ago. I hiked in this area in the mid-80's and the river was practically dry, you could easily hop from one side to the other. 11:14 A friend, Wile E. Coyote, advised you not to remove that small quartz rock.
I thoroughly enjoyed this video as I have been for a month or so now watching previous videos here. Please continue! In fact, more frequent videos would be great with me. Thanks for your work!
Guddness alot of changes to the landscape! We had simlar destruction here in upstate of sc though ours was mostly high wind damages. i Recently walked a few of are creeks and rivers bottoms, we have major trees down all thur out our drainage area, very concerning next time we have a flooding rain!
21:45, the river bank washed out to the foundation of that house, parts of it fell off, and the park just up stream of it was wiped out. The next house up steam the first floor was flattened. Duke power used helecopters to fly in power poles to get electricity back in to the community.
Interesting. I was blown away by the level of damage in there. Did everyone make it out alright? For some reason I had literally never been down in there before heading down for road evals after the storm, so I didn't have a sense of what it used to look like.
thanks for being all over this and your xplanations n footage is remarkable st.helen eruption n helene flood are my two geo fantastics hope the yellowstone happens in my time also,keep us posted
THAT is just crazy! The enormous wide spread devastation! Those huge boulders that DID move! This helps me to better comprehend the small creeks that turned into torrents!
I’ve never been there to see what it looked like before and it looks amazing now. You have a very informative video. I wonder how many times over the millions of years the rivers in this area have gone through this process. Probably hundreds or more. We’re just a blink in the time span. So sad for the loss of life in the hurricane.
I own an old grist mill in loafers glory NC. The building is still standing but boulders the size of trucks got moved around, and a chunk of the dam is now pinned by a huge boulder. Crazy change and craziest is that the septic field/streambank/house was unaffected by all this. Come by and check it out
Awesome video and findings by time lapsed comparison of geological layout and manmade structures locations. Enjoy the narrators natture and simplistic approach to detailed coverage.
its so shocking to see it!! can you imagine what it must have sounded like and looked like coming down those mtns??!!! its almost unbelievable so destructive and awful thank you for doing these videos i appreciate you
I really enjoy your videos..they are very well put together. You make sense out of what has happened to such a beautiful part of this country.Keep up the great work! God bless
I'm a pretty analog guy myself...but I do love some satellite imagery and lidar! Glad you enjoyed the video. I'm trying to keep folks thinking about what happened in this neck of the woods!
Hi Phillip. Such interinsting videos you present, thank you. It’s beautiful rock, landscape and water. Have been watching treckers in Napal you’re area is just as pretty in a different way. Where did all the excess earth end up? So much land was taken away were new mounds formed? Could you superimpose the wind-rain currents of the storm over the areas you’re showing us. Thanks.
Thank you for this video. The scale of destruction and land alterarion is mind boggling. Looking forwaed to your Henderson County overview. The craggy rocks remind me of Carter County in Eastern KY. My grandpa's farm was nestled below huge rock outcrops! I can imagine the tiny stream next to the yard doing something similar to what happened in Henderson County NC. It would have flowed into the river that was in front of the house, that had already been somewhat controlled by concrete banks. Probably hundreds of years ago! Hope you feel better soon, and tgis doesn't develop into long covid. 😊
I sure would like to buy you a cup of coffee! You have really made amazing use of the NOAA data. Thank you for educating me and many, many other people!
Brave man, standing under that featured rock that could go at anytime.... Thanks for your geological explorations of this flood. As disastrous and terrible as it has been, it's fascinating to watch what you're seeing. You are right about the sand in that area. I noticed that in videos even to the north and east of this where I'd expect to see red clay, there are enormous deposits of sand.
I’m a civil engineer who did flood studies and designed facilities based on those studies for many years. The “can’t happen here” mentality has to change. I’ve witnessed flooding and the aftermath similar scenes as these but the scale of this over such a huge area is mind-boggling. Stating the obvious, even small streams can become deadly destructive torrents under the right circumstances. I feel really bad for these poor folks. Thanks for your videos!
What struck me the most when I started seeing videos post-Helene is how similar the rivers looked to rivers I've fished in Washington State on the Olympic Peninsula, the Queets River in particular. I spent a lot of time looking at USGS river flow data to gauge when to go fishing and the Queets has some amazing flows. Tonight it is around 8000 cfs, but there were some events in the 90's that saw it up to133000 cfs. Thoughly scoured everything and some of the old fellas I fished with said you could feel the boulders bouncing down the channel. And that sediment you're seeing washing down? There has always been enough of it to fill up that dam (or any other dam we've built). Thanks for your account!
The denuded stream banks give a fascinating looks at the local geology, something we rarely see with all of the vegetation that is normally present. The country rock has a very "Gneiss" look to it.
the way the fluidized soil acts is strange. it moves like water but is more dense, so it can nearly, but not quite, float boulders. they do move more easily. people that clean up after one always talk about the boulders still “floating” in mud
This was a fairly historic event and you did a thorough job with your analysis. It would probably be helpful with videos like this to include exact coordinates for some of the most distinct features. That way if there is a future landslide or other event that changes the landscape again there is a detailed record of it. A copy of this at a couple of nearby colleges especially, if they have a geology course and/or collection of local rocks would be nice. My favorite parts of those courses was always field work and that way they could make a field trip to keep an eye on future changes to keep an ongoing record. Given the pace of said changes over time I think younger people might have to take over the observations in the distant future :)
Thanks for your videos, really interesting, I just discovered them and subbed. What you showed about the soil being scoured away here hit a chord because of a book I just listened to about soil loss called A World Without Soil, apparently soil loss is a huge problem worldwide. Much more is being washed away in the last hundred years than is being generated, mostly because of plowing, but also from roads and mines and other human impacts, and then big weather events added on top. Despite the depressing title the book was actually pretty interesting about 'dirt'! I had never thought of soils as ancient and mysterious - scientists still only know a fraction about the microorganisms that inhabit and create the different types. Geology nerd here, never took dirt very seriously before!
I saw his first video the other day and was extremely impressed, he's a great presenter and educator. Holy moly, what a catastrophic event!. If you worried about our US politics, worry more about Mother nature.
My grandkids play in the Big Hungry. There used to be a large shallow pool of water that they'd swim in and shallow dive/ jump off the surrounding rocks. They always took a lunch and drinks and swam with all the other kids that showed up
So we could say the dam was more-so acting as a rather inefficient basic weir? Very cool video. The geology is fascinating. Most of the soil landscape in the far north east Canada where I am from is overlaying late Devonian bedrock with no sandstone on top; so while on the surface it can often look similar the bedrock is truly a whole different beast.
yes, a really badly built weir. there’s still a surprising amount of it there. it would be fascinating to have watched that dark gray reduced environment sediment enter the flow. the channel didn’t appear migrate much through the stored sediment. I figured it would get rid of most of it.
@@TheGeoModels In your shots immediately upstream of the dam you can quite clearly see multiple broken off layers of sediments that have slightly shifted but remained in place. Some broken off pieces even display multiple layers of more modern sedimentation. An amazing display of sedimentation. It also really completes the picture with the story of how the reservoir filled with sediment over time.
@@taninogi it's really cool to see. I need to go take some more shots of it. It probably indicates a high rate of sedimentation from the upstream area, as the reservoir filled in a short period of time. There are leaf layers buried between the sand/mud layers, and local foreset structures from where the whole package prograded out. It's remarkable to see.
Having walked hundreds of these Appalachian streams before Helene, this is absolutely insane. So much exposed bedrock.
it is. glad someone backing me up on it! it genuinely makes the land look different.
i third this

Although we can't see what's in your mind of before and after the rain, it's fun to read pre flood memories of those landscapes. Thanks!
@@rt3box6tx74 They were generally darker, more vegetation sheltered, and "slicker" in the sense that rocks had various biology and botany on them...

Easy on her paws and amazing tennis ball fetching. I took some pictures of the dam during the event on both Thursday and Friday.

I got excited when i saw this video get posted while watching another one of your videos! Another level of education getting to see the human scale and perspective of a cataclysmic event.
thanks!
All of these rivers post Helene look super clean as if they were sandblasted by the bed load and the suspended load of the rivers.
Truly a massive cleaning out and I am seeing lots of channel migration and relocation.
Keep up the good work with your videos. Great information for so many.
yep, interesting relocations above here. some of the attempted relocations out in the flats of clear creek and cane creek are also quite interesting
Little over a hundred years ago, my step family came to the Ozark foothills of Missouri. They knew back then not to build near water unless you had a very high bank with a low bank across from it with room for the water to spread out. I am amazed by the people who built in some of these places rather than higher ground. When you have this set up you farm/garden the creek banks but never put a home there. Maybe an animal shed but you expect to lose it every so often so real basic. My grandfather said that if it was bound on both sides go at least twice as high as the highest historic level by the memory of oldest folks around. He built his homestead on a high bank that was forty feet above the creek with hundreds of acres across from it to flood. Of course he had nearly a thousand acres to choose from. Last time I was down that way the homestead house was still there. And yet in the mountains a landslide can get you even if you are on high ground. Roll of the dice I guess.
You can read the topography and avoid the debris flows, at least in most cases. Trouble starts when they are bigger and go farther than expected!
A lot of people were well out of the 1000 year flood plain and still had their homes destroyed. Forty feet above the creek like your grandfather built wouldn't have necessarily saved his home in an event like this. It's been frustrating to hear people not from here saying folks shouldn't have built in the flood plain... they didn't and their homes were still destroyed by flooding or debris flows.
So you don't know what you're talking about in terms of our mountains.
Most folks weren't even near the river or creeks
This is my absolute favorite YT channel. Having my husband watch geology videos w me used to be the equivalent of him dragging me along to Guitar Center...but your channel is so interesting that he's now a subscriber, too. So thank you, genuinely, for the hard work and time it takes you to make these videos.
well I am glad yall got some programming you find interesting! Pleased to hear you find the vids useful!
Been waiting on this!!! Much love from rural Burke Co. Thanks for educating us for free!
haha no prob. the green will get attention too. big hungry was rowdy though. the concept of Oleta road flooding as it did remains very bizarre to me.
@TheGeoModels I spent the day at wilson creek today. I live between wilson creek and Linville and there are definitely changes to both. I want to check out Harper's Creek too. At the confluence of Harper's and wilson, a bridge was damaged, so I image the flow was significant
Hello from 181 in Oak Hill 👌
I couldn’t even recognize where you were. Unbelievable. Great video again and I really you hope you continue to do these “from the field” style videos even after your coverage of Helene aftermath ends!
It's a crazy place in there. Had no idea it got hit so hard til I dropped down Deep Gap
there are so many of these places I’ve spent so much time and I’m a little scared to go back. Thanks again for the videos man, it’s really been a good way for me and I would imagine a lot of other people to process what happened a little better. Cheers!
This is the video talk I've been waiting to see. I've been so curious what the scoured steamed beds and gorges look like post flooding. Amazing power of water! I'm impressed with the way you rock hop and scamper over cliff faces. I'm happy now to take the vicarious hike with you behind the camera and commenting as you go along. The maps were great too to visualize the pre and post views. Very interesting!
I heard my Mom and Dad and cousins talk about these places such as Pensacola but until I watched your videos I did not realize just how close some of these places were to the ones I knew (born in NC and went back to familiar stomping grounds at least yearly), but seeing your videos and maps made me realize some of them were just over the mountain from those I was familiar with. Thanks much for the Lidar and the hiked videos. I think I will wait a bit before attempting an in-person visit 😢; meanwhile prayers and as much support as possible for my Carolina cousins. Thank you for your excellent and informative videos without which I might have been hesitant to venture back later into those little hollers where my ancestors rest, truly some places I wondered how they ever found.
Exceptional. This landscape architect can't get enough! Sorry for the loss of so many family homes, businesses and lives Thank you for these valuable lessons, as they must be recored, remembered, and applied.
thanks
How that water cut through that bedrock is incredible. I heard one community member state “it sounded like a freight train”…it must of been terrifying. No wonder people are missing..I pray for them and their families ✝️
well it cut the bedrock over a great period of time, but it certainly knocked a few chunks out this time around. desk sized boulders would have been tumbling down that little gorge. I bet you could feel it rumbling if you were close
14:53 I most certainly saw a major change in river color and density during the big surge arrival in the Green River Cove by the Upper Bridge across the Green. The odder even changed and trees got pushed over quickly and the "liquid landslide" scoured the lower cove. That sediment may not have been water but that mud still have volume and it definitely added to the surge displacing more water. It also increased the density and impact. I watched this unfold with my own eyes from the porch of the Green River Ranch across from my property just below that bridge I mentioned. Thank you some much for sharing this video and your insight Philip Prince. I owe ya a few beers when I ma back in the area,
Most of my work is focused on western NC, and comprehending Helene's short- and long-term impacts requires folks such as you. Thank you for sharing your insightful and compassionate dedication to your craft with all of us.
‘Been binge watching your great videos lately. Fascinating stuff. I bet geologists and archaeologists are eager to explore this unprecedented event.
Yes, it will contribute to geologic understanding, particularly in terms of landscape history in the Appalachians. Many deposits of stored sediment have been laid bare, so folks can see how old they are now and figure out how long the landscape has looked like it does, etc. etc.
@ Calling Graham Hancock.
I am fascinated in how water changes landscapes. Your vids are wonderful.
Thank you
Love me a Phillip video! Hello from Michigan -Connie
Thanks Connie!
These are such great videos to educate what happened in all of these different places during Helene. So many trickles became big streams and streams became raging rivers and rivers well there isn't a description of what they became. As I said before, our stream or creek was about 15 ft across. Had flooded many times. That day it was about 100 ft across. I've never seen anything like it and hope not to again. I still stress when it rains and we were one of the lucky ones. Even our creek, which is an extension of the elk river, has stones and boulders everywhere and trees laid down all along it. Please continue educating us on this. It's horrifying and yet interesting and informative at the same time!! I'm also tickled Brad Panovich discovered you!! He is the reason I was so prepared in Avery County the day of the storm. He kept saying I'm really worried about our friends in the mountains. I thought ok let's prepare!!
Yes I saw he posted that debris flow video up. Glad he found it worthy!
Thank you. What a flood on my birthday. Blessings to all of the people that had to endure that event.
I live just a few miles from here and it’s really incredible to see how clean the river is no dirt no moss or anything. I’ve never seen anything like it!
Thank you for publishing these videos, it is extremely helpful in understanding the scale of this event. I look forward to the next ones.
Thanks for watching. Trying to tell the tale from the earth process side of things, as well as how people have had to interact with it.
I just wanted to thank you for all the informative videos, you have definitely helped me to understand what exactly happened in that area. My heart breaks for everyone affected by Helene!
It was a big one. Here's hoping we don't see another!
your content is top notch my guy. thanks for the free lessons on the beautiful world around us and how powerful the landscape and water can be
Glad to provide it. Hope it keeps folks thinking!
Philip thank you a million times! You're so informative and so fascinating. Thank you so much for all that you do! You're our favorite geologist
Another field trip!! Epic stuff man
Watching your channel makes me wish I had become a geologist instead of going into the tech industry. Very interesting stuff man!
There's cool things to consider, for sure. Imagery technology has totally change the way geology is practiced in recent years, for sure!
Your records are a treasure for so very many vocations forever! Kudos for your efforts - wish we could nominate all of you reporting this history for a significant award!
well the comments are pretty good too. Thanks for watching
We have property on Citico Creek in TN and it floods about once a year. It doesn't get too far out of the creekbed but the size of the rocks and small boulders moved by the force of the water is mindblowing. And frightening to think about the consequences had Helene's course been slightly different.
I am used to hopping rocks in the Appalachians, so I know what ya mean lol Really enjoying these videos on the geomorphic impacts of Helene. Hope you feel better soon!
Yeah I'm squared away---thanks! it's funny to move through there with such ease. The friction on the rocks is great. It reminds me of some gorges in Jamaica that get floods like this annually.
These on location videos are superb, glad Chris pointed you to the NOAA imagery
Fascinating video. We live in that subdivision where the bridge got washed away. Thanks for sharing the story of what happened down here on the Big Hungry River.
Our house has gullies on either side of it, both with seasonal streams. But they both turned into torrents during the storm, with 14 debris flows that broke loose. We kept hearing trees fall followed by what sounded like a large truck driving on a gravel road. The flows took out a large chunk of road and our neighbors' septic field and pond, but the houses were spared.
The video shows a house that was hit by a landslide. There was another place just to the west of it, essentially a fifth wheel camper set up like a home. The frame of it is now in the river about half a mile downstream.
There was another couple that live just upstream from the landslide-hit house. They sheltered in their attic, and could reach down and touch the water going by. Thankfully their place stood.
If you do come back to shoot more video of the river, I would be happy to show you some of the areas in the subdivision that might be hard to access without an escort.
I'd take you up on that. Interesting to hear some of the folks' stories. I wanted to be sure I did this video because of the scale of the impacts in there and the fact I didn't ever hear about it anywhere. The area was absolutely flooded as intensely as anywhere else. It's hard for me to visualize what it would have looked there where Tumblebug comes in. There's an email at the link below--drop me a line!
princegeology.com/about-philip-prince/
Gracious me!
Fear is definitely not created equal.
Being able to feel the creek water flow just by reaching my hands down while I'm sitting inside my attic has got to be fear on the edge of insanity. Merely trying to comprehend such an acute upside downing of everything around is what nightmares of the worst kind are made of.
Much love and warmth to you and those you love!
Ive personally been in flood zones of this magnitude fresh after. It changed my life forever to feel that.
Thanks for the information. I can’t believe how the small rivers re-routed and I appreciate your explanations.
Excellent presentation. Thank you. Looking forward to the boulder movement video. I have often wondered how they got where they were and their subsequent movements. What a great opportunity to study that.
This channel has helped me make sense of what happened all across the area.
I live in Avery County N.C. on Birchfield Creek which runs into the North Toe River right below the Minneapolis community. We have never seen so much exposed bedrock and river beds. Area's that use to be acres and acres of beautiful river side properties area just GONE!! It's unbelievable how much dirty was moved.
Thank you for sharing your knowledge . And the film and photos . It’s very interesting . ❤ to all the people affected . From North Wales 🏴
There was a geologist working in the 40's - 60's named Luna Leopold who showed, for the fist time I think, that contrary to popular opinion, streams and rivers do little or no erosion to their beds day and day out. It's only in those brief times when a large flood comes through where the entire bed of the stream system gets lifted and churned into the flow, and large cobbles and boulders begin moving and bouncing down stream that the channel gets eroded. It has probably been thousands or even tens of thousands of years since those Appalachian streams have experienced flows on that scale.
Probably true. Flood energy is not a linear thing, in the sense that a flood "twice as big" would have many more times more energy associated with it. Things definitely got a good shake this time around. It would be interesting to know how floods looked during the Pleistocene. They might have regularly been even bigger!
We had similar flows in 1918 and probably several more times in the thousand years before that.
the notion that low flow streams carved out bedrock is just pure nonsense; The New River was considerably higher in the past; as a contractor/landscaper/equipment operator, I've dug around all over the place around the river, and in many places I've dug into smooth river stones and boulders layered 6-10ft thick in veins (some the size of cars), 150-200ft above the current river levels. And this is in Ashe Co., near the head of the river.
These mountains and valleys weren't carved out by a little water over a long period of time, they were carved out by a lot of water over a relatively short amount of time
@@wildbill6976The same New River that runs through WV?
What ?

Covid
Thank you. You really explain this event well and it’s hard to imagine how severe
It's something to see. Doing my best!
Keep 'em coming, your work is riveting!
Looks like the Andes too! I plan to visit Cove Creek and Little Cove Creek when I return stateside. Thank you for sharing this. I witnessed the flood downstream in the Green River Cove.
Thank you for recording this information and these places for their historic value as well as scientific value! I am sure others viewing this will see more information in them than you imagined! Great work!
These are amazing videos. Thank you for recording what happened. Important for recording the history of this flood.
After the Ivan flood, the national park service had the opportunity to mark the high water point on the trees around their parking lot at Linville Falls. Those cars would’ve been about 8 to 10 feet underwater.
This flood drives that flood out of memory But it would’ve been nice if those who visit the area Goode at least had an idea of what that river could do !!
Another hundred years and we will forget that there was ever a flood in Asheville or Black Mountain or chimney rock…. Unless people preserve the record.
This is so interesting. I noticed on some of your other videos that the rocks walls looked like a thrust had happened long long ago. As tragic as this event was there has been so much info in your field. Thanks for all of the information. I'm learning a lot.
Thanks for showing the befores and afters of the devastation from Helene. I appreciate your work and your videos also provide a distraction from the other news of the day.
Thank you. Trying to get the stories out there.
Wow, just finished watching, thanks for the field trip, and the wrapup with the great overview. I'm looking forward to your investigation of how far those huge boulders moved during the flooding. The power of water is amazing, your videos are helping me visualize geologic timescales of mountain removal! I hope you are feeling better, btw.
I am good, thanks! the biggest ones didn’t go far, but they did move for sure. I admit I have yet to be satisfied with my reconstruction of that spot!
One of the small creeks in Boone, NC had a distinct blue/green tint to it after the initial sediment settled out. Much like glacier fed creeks I have seen elsewhere. My guess is that the grinding action of the rocks created a larger of dissolved minerals than usual. Very interesting.
I'm addicted to your videos. Love the Appalachians, and amazed by what happened up there. Your videos have explained it in ways that make sense (well, sort of...) and spark intrigue.
On a side note, I found some really good imagery with soar.earth as well. Really high resolution, and... Layers 😁
comment a link with that imagery if you can
Wonderful video!! From what I've read on the great Connecticut floods of 1955, it was also the very small (many of them usually dry) tributaries that did the bulk of the damage there, too. This resulted in the entire state being declared a major disaster area.
Thank you for sharing your experience. As a biologist and a native to the mountains, my heart is crushed by the destruction of habitat-for plant, animals and people😢
Your videos and this disaster is turning me into a new lover of geology ❤
Remembering the geological history of the Scour Lands up in the NW area of the USA, and the Mt. St. Helen debris flows = your videos show a much smaller scale of what Hurricane Helene did to this particular Appalachian river system.
Just think! To us mere mortals, your videos are amazing to see the scale of human beings to this!
Folks, this is the power of geological forces on our planet, impacted by weather and climate change events!
Thank you, Philip, for sharing your knowledge and study area with us!
I live in a very tiny, remote community way back in the Appalachians. My creek is usually 6 inches deep and maybe 3ft wide.
That creek swelled into 100ft wide and ranging from 2ft to 10ft deep. Never in my life have I seen that. The entire streambed is changed. It doesn't flow the same.
From what I have seen and heard, that was sort of what this storm did where it hit hard. the funny thing is that if you go west of the hard-hit area, things taper off quick and it's business as usual. if you got under one of the intense bands on Friday morning, though, different story...
Thankyou. What a crazy event. We need to make sure all areas like this get looked at. It is still just unbelievable.
Thank you so much. Is there anything remaining of the other dam on the river? I don't know if it was removed before the storm, I only remember it being debated years ago. I hiked in this area in the mid-80's and the river was practically dry, you could easily hop from one side to the other.
11:14 A friend, Wile E. Coyote, advised you not to remove that small quartz rock.
I thoroughly enjoyed this video as I have been for a month or so now watching previous videos here. Please continue! In fact, more frequent videos would be great with me. Thanks for your work!
will try to keep it going
Wow, that sense of scale really made it clear! Watching Letsdig18 digging out mountains of flood mud also shows where it ended up.
quite a bit moved for sure!
Thank you! As a Hendo county native it’s crazy to see how those areas were impacted by Helene. Love the content informative as always!
Laurel Park area was nuts too
@ I know! I have some close friends up on Echo Cir next to the Echo Mountain Inn…I saw a lot of crazy pics from them once they got cell service back.
Guddness alot of changes to the landscape! We had simlar destruction here in upstate of sc though ours was mostly high wind damages. i Recently walked a few of are creeks and rivers bottoms, we have major trees down all thur out our drainage area, very concerning next time we have a flooding rain!
21:45, the river bank washed out to the foundation of that house, parts of it fell off, and the park just up stream of it was wiped out. The next house up steam the first floor was flattened. Duke power used helecopters to fly in power poles to get electricity back in to the community.
Interesting. I was blown away by the level of damage in there. Did everyone make it out alright? For some reason I had literally never been down in there before heading down for road evals after the storm, so I didn't have a sense of what it used to look like.
thanks for being all over this and your xplanations n footage is remarkable st.helen eruption n helene flood are my two geo fantastics hope the yellowstone happens in my time also,keep us posted
THAT is just crazy! The enormous wide spread devastation! Those huge boulders that DID move! This helps me to better comprehend the small creeks that turned into torrents!
I’ve never been there to see what it looked like before and it looks amazing now. You have a very informative video. I wonder how many times over the millions of years the rivers in this area have gone through this process. Probably hundreds or more. We’re just a blink in the time span. So sad for the loss of life in the hurricane.
An excellent reconnaissance. Good detailed observations. And great use of remote sensing. I look forward to your next video.
thank you
I own an old grist mill in loafers glory NC. The building is still standing but boulders the size of trucks got moved around, and a chunk of the dam is now pinned by a huge boulder. Crazy change and craziest is that the septic field/streambank/house was unaffected by all this. Come by and check it out
Awesome video and findings by time lapsed comparison of geological layout and manmade structures locations.
Enjoy the narrators natture and simplistic approach to detailed coverage.
its so shocking to see it!! can you imagine what it must have sounded like and looked like coming down those mtns??!!! its almost unbelievable so destructive and awful thank you for doing these videos i appreciate you
thank you
I really enjoy your videos..they are very well put together. You make sense out of what has happened to such a beautiful part of this country.Keep up the great work! God bless
thank you
Another great video! Can you do a video on impact to canton and what happened to the paper mill area and down stream.
Thanks for Taking US out into the Field with You! Grad with BS Geology 1980..stoneage Technolgoy Thanks for all the MultiMedia information
I'm a pretty analog guy myself...but I do love some satellite imagery and lidar! Glad you enjoyed the video. I'm trying to keep folks thinking about what happened in this neck of the woods!
Hi Phillip. Such interinsting videos you present, thank you. It’s beautiful rock, landscape and water. Have been watching treckers in Napal you’re area is just as pretty in a different way. Where did all the excess earth end up? So much land was taken away were new mounds formed? Could you superimpose the wind-rain currents of the storm over the areas you’re showing us. Thanks.
Thanks for taking the time to teach everyone! Looking forward the next video.
Are you going to be doing a Q and A?
As you were stepping into the water, my inner self screamed Watch out for the slime! 9:41
I love your channel. I loved my geography class in college❤
Very interesting. Appreciate all the work and time to explain how this event happened in the mtns.
Amazing. Thanks for giving us an 'on the ground' perspective.
Thank you for this video. The scale of destruction and land alterarion is mind boggling. Looking forwaed to your Henderson County overview.
The craggy rocks remind me of Carter County in Eastern KY. My grandpa's farm was nestled below huge rock outcrops! I can imagine the tiny stream next to the yard doing something similar to what happened in Henderson County NC. It would have flowed into the river that was in front of the house, that had already been somewhat controlled by concrete banks. Probably hundreds of years ago!
Hope you feel better soon, and tgis doesn't develop into long covid. 😊
Thank you for your fantastic videos!
I sure would like to buy you a cup of coffee! You have really made amazing use of the NOAA data. Thank you for educating me and many, many other people!
Hard to turn a cup of coffee down! I'll do some more with the NOAA imagery. It's quite good.
Brave man, standing under that featured rock that could go at anytime.... Thanks for your geological explorations of this flood. As disastrous and terrible as it has been, it's fascinating to watch what you're seeing. You are right about the sand in that area. I noticed that in videos even to the north and east of this where I'd expect to see red clay, there are enormous deposits of sand.
I’m a civil engineer who did flood studies and designed facilities based on those studies for many years. The “can’t happen here” mentality has to change. I’ve witnessed flooding and the aftermath similar scenes as these but the scale of this over such a huge area is mind-boggling. Stating the obvious, even small streams can become deadly destructive torrents under the right circumstances. I feel really bad for these poor folks. Thanks for your videos!
What struck me the most when I started seeing videos post-Helene is how similar the rivers looked to rivers I've fished in Washington State on the Olympic Peninsula, the Queets River in particular. I spent a lot of time looking at USGS river flow data to gauge when to go fishing and the Queets has some amazing flows. Tonight it is around 8000 cfs, but there were some events in the 90's that saw it up to133000 cfs. Thoughly scoured everything and some of the old fellas I fished with said you could feel the boulders bouncing down the channel. And that sediment you're seeing washing down? There has always been enough of it to fill up that dam (or any other dam we've built). Thanks for your account!
Fantastic video, covering the extremes of fluvial processes.
The denuded stream banks give a fascinating looks at the local geology, something we rarely see with all of the vegetation that is normally present. The country rock has a very "Gneiss" look to it.
The force of pressure of all those trees piled up can probably move some big boulders too. Great video, thank you.
the way the fluidized soil acts is strange. it moves like water but is more dense, so it can nearly, but not quite, float boulders. they do move more easily. people that clean up after one always talk about the boulders still “floating” in mud
This was a fairly historic event and you did a thorough job with your analysis. It would probably be helpful with videos like this to include exact coordinates for some of the most distinct features. That way if there is a future landslide or other event that changes the landscape again there is a detailed record of it. A copy of this at a couple of nearby colleges especially, if they have a geology course and/or collection of local rocks would be nice. My favorite parts of those courses was always field work and that way they could make a field trip to keep an eye on future changes to keep an ongoing record. Given the pace of said changes over time I think younger people might have to take over the observations in the distant future :)
Thank you for your teaching, Philip, I enjoy it! 👏👏
Great coverage very insightful
Thanks for your videos, really interesting, I just discovered them and subbed. What you showed about the soil being scoured away here hit a chord because of a book I just listened to about soil loss called A World Without Soil, apparently soil loss is a huge problem worldwide. Much more is being washed away in the last hundred years than is being generated, mostly because of plowing, but also from roads and mines and other human impacts, and then big weather events added on top. Despite the depressing title the book was actually pretty interesting about 'dirt'! I had never thought of soils as ancient and mysterious - scientists still only know a fraction about the microorganisms that inhabit and create the different types. Geology nerd here, never took dirt very seriously before!
the carbon flux from soil stuff with this event would be something to tabulate!
I saw his first video the other day and was extremely impressed, he's a great presenter and educator. Holy moly, what a catastrophic event!. If you worried about our US politics, worry more about Mother nature.
Curious to see what you find regarding the where the landscape materials settled downstream. Even Lake Lure had to overflow, to some where.
Crazy how such a little stream could turn into such a catastrophic event. Thats alot of rain!
My grandkids play in the Big Hungry.
There used to be a large shallow pool of water that they'd swim in and shallow dive/ jump off the surrounding rocks.
They always took a lunch and drinks and swam with all the other kids that showed up
So we could say the dam was more-so acting as a rather inefficient basic weir?
Very cool video. The geology is fascinating. Most of the soil landscape in the far north east Canada where I am from is overlaying late Devonian bedrock with no sandstone on top; so while on the surface it can often look similar the bedrock is truly a whole different beast.
yes, a really badly built weir. there’s still a surprising amount of it there. it would be fascinating to have watched that dark gray reduced environment sediment enter the flow. the channel didn’t appear migrate much through the stored sediment. I figured it would get rid of most of it.
@@TheGeoModels In your shots immediately upstream of the dam you can quite clearly see multiple broken off layers of sediments that have slightly shifted but remained in place. Some broken off pieces even display multiple layers of more modern sedimentation. An amazing display of sedimentation. It also really completes the picture with the story of how the reservoir filled with sediment over time.
@@taninogi it's really cool to see. I need to go take some more shots of it. It probably indicates a high rate of sedimentation from the upstream area, as the reservoir filled in a short period of time. There are leaf layers buried between the sand/mud layers, and local foreset structures from where the whole package prograded out. It's remarkable to see.
I absolutely love this channel!
