- Floods of lava (Columbia River Basalts) and Ice Age Floods of water (Lake Missoula floods and the Bonneville Flood) are world-famous topics among geologists. To have both sets of floods in the same area means the geology of the Inland Northwest is truly Disneyland for Geologists!
Tom Foster (HUGEfloods.com) and Nick Zentner (Central Washington University) have been hiking together in eastern Washington for years. The result? A series of short videos that showcase geological wonders in the Pacific Northwest.
This 16-minute video - Huge Floods in the Pacific Northwest - offers an introductory overview of spectacular geologic events that impacted much of Washington, Oregon, and Idaho.
The program begins in Lewiston, Idaho where the floods of lava and water are beautifully on display near the mouth of Hells Canyon. Early on, the Columbia River Basalts - eruptions of fluid lava from deep fissures - are featured. The Missoula Floods from Montana and the Bonneville Flood from Utah - the Ice Age Floods - are surveyed at an introductory level. And finally, the interaction between bedrock and fluid dynamics of the floodwater are highlighted through discussion of Ice Age erosional and depositional landforms. Key locations in the Pacific Northwest are featured, including the Snake River Canyon, Grand Coulee, Dry Falls, the Drumheller Channels, Wallula Gap, and the Columbia River Gorge.
More than a dozen ‘2 Minute Geology’ episodes are now available online.
Nick Zentner is easily the best and most captivating teacher of hard sciences that I've ever seen.
If anyone had told me, two years ago, that I would get hooked on videos of some guy standing in front of a chalk board, talking about rocks, I'd have told you that you had rocks in your head. Now I am considering going back to school to study geology.
Thank you, Nick.
All my Geology Profs were good at Portland State. Rice University had good folks too! Nick seems great too.
@@richardmarty9939 I don't know what it is about geology. It just attracts passionate people. Or at least passionate teachers.
In tiny Singapore, where I live, the tallest point is just 163 meters high. It is a granite outcrop said to be about 400 million years old. The fascinating thing is that it sits on top of another layer called norite which is 200 million years younger. If not for this channel I never would have taken an interest in the geology of my own country.
Thank you Professor Zentner.
My house is about 300 yards from the impressive deposit in Lewiston from both floods. See it everyday. There was a certain bottle neck at this spot from bonniville. A gravel pit is at this location. And a gap like at wallulla.
These videos are so awe inspiring! Thank-you for doing this! And, I'd like a ride in that ultralight...!
Thank you, Deborah! Nice to hear that these videos are working for you.
Fascinating
Why are the basalt floods not called the Colombian (Columbian?) Traps?
Only yesterday, I discovered these videos, and I am SO IMPRESSED!! Surely I have never seen information and teaching like these on any Nat Geo or BBC programs. Being a trucker, I have passed through many of these areas a dozen times, and yet not knowing how all of this was formed and by what means, until now!!
I am a new subscriber gaining more and more knowledge following each and every video. Thank You Nick!👍
Nick is a Pacific Northwest treasure. National treasure in my mind. To find a professor who is willing to share his knowledge with anyone who is interested and have such passion in his heart to do so is a blessing from a higher power.
Although i am coming to the party very late, I am blown away by the information and knowledge that I have learned from Nick. I didn't discover him until two months ago - It has changed the way i look at the world - and i am better because of it. I look forward to learning more about the planet we inhabit. Thank you
Professor Zentner is a fantastic geology professor! I already knew a portion of this, but not nearly as much as after watching this video. I'm once again all fired up on physical, and even historical geology :) Can't wait to start watching more of Professor Zentner's videos again.
I'd like to hear Nick's thoughts on the "energy paradox". No thermal heating has been explained that would have been sufficient enough to melt the entire icecap in the time it was melted. With current heating simulations we still should have an ice cap. If this is not explained all the theories of ice dams go right out the window.
Nick you have an incredible mind, most see it as just beautiful earth features, but you bring it to life. At first I saw just mounds of dirt, hills on valley floors, boulders jutting out the landscape in miscellaneous locations, then you come along and give explanations that make so much sense that it is hard to believe these are not obvious to normal eyes. I can't look at these things now and unsee it the way I did before. You are incredible. I want to take you on vacation all over this country just to hear you explain what I am seeing. Your voice, your delivery, your stories of what was happening years ago forms vivid images as you speak of them, my mind can just picture what was happening. I am so glad I found your videos, I think I have seen them all, can't wait for some new ones. Thanks a million, you are a true gem, your students are very lucky.
Thanks for the enthusiastic comments. Very nice to hear that our videos are working for you.
Check out alternative views. They might be enlightening
Hey nick. I think mongo s got a little crush on you. I hope for your sake your secret admirer is a girl. But not jessica walter from. Play misty for me
I use to take my my kids on trips and talk to them about the history of the area we were passing thru.
I got teased about it pretty good by the time they were !0 or twelve; You have to be open to information and want to learn. Or they might call you Mr. Wizard
Thank you so much for taking the time to make these videos and for explaining these incredible features.
Thanks for watching, Kevin. Nice to hear.
What was/is unique about Wallula gap that was able to stop a flood of a magnitude that could carve hundred-foot deep coulees out of basalt?
This video is causing me to miss summertime road trips in the Jeep with the top off. Next time I'm in the over there I will have a better idea what I am looking at. We live in such a dynamic area.
Road trips are the best!
I look forward to each and every video👍🏼👏🏼👏🏼♥️thank you professor Nick 👍🏼♥️
I stumbled on your RUclips channel a couple of weeks ago. I love watching your videos and want to learn a lot more about geology. Please come to Capitol Reef NP and make a video. ;)
You should have 30 million subscribers! Awesome.
Dr. Zentner, you're my favorite geologist. I enjoy your lectures tremendously. I wonder if you have looked at the geology of the northern half of Africa. It has a very similar appearance to the Pacific Northwest Missoula flood scars. It's very interesting. The Ricat Structure, which appears to me to be a volcanic feature, may hold clues to what was going on. It seems to me, some incredible pressures from below the surface may have caused water to rise through the strata and flood the whole land. Since I am given to understand there were no glaciers there, and since it is now desert, I keep thinking of a line from ancient scripture. "The fountains of the deep broke open..."
This is so amazing, thank you!
Thanks for watching, Billy!
I like to play devil's advocate most of the time but I have no ammunition! This was a wonderful video and the topic was something I was really really interested in. Thank you for the presentation and the information sir
When you launch that augmented reality app for our phones and tablets, please let us know here. Can't wait to see animations of the floods in an overlay on the present day image as seen through our ipads. No pressure or anything ;-)
Cool idea!
Me, too!! I have wished to see a film of computer graphics creation of the Bonneville flood as lifelong Idaho resident! I wonder how it sounded! I have asked a Native friend if she knows of any Native story about the Bonneville Flood but she has not gotten back to me on it.
whoa ! whoa ! whoa ! WHOA "!!!!"
Thanx Nick ...("WHOA" !!!!!!!***)
👍 👍 👍 👍 👍 👍 👍 👍 👌
I'm amazed every time I watch this.
Imagine Nick as a grandfather teling his cuties these stories at bedtime. Reminds me of PRINCESS BRIDE, a stretch I know, but his stories are just as exciting.
Didn't know you have this channel, Nick. Will be checking it all out!
We need your twin in Arizona.
I concur wholeheartedly!!!!
I would like to hear your expert analysis of the Missoula Floods' influence upon forming the very fertile Willamette Valley.
Additionally - Due to geological considerations (partially) scuttling the Yucca Mountain Nuclear Waste Repository, I would like to hear your opinion as to a geologically ideal site for such a facility. Hanford is clearly less than ideal.
Damn that Canadian ice invasion, someone should have built a wall!
As I watch these type videos I imagine the roar and rumble of the floods. I've seen some small scale floods (my hometown creek during the spring thaw, no more than twenty feet wide and twelve feet deep) and they can make some noise! Imagine being a large bird gliding over these areas amidst any one of these dynamic floods events. That would be cool!
Really interesting!
👍 This is very interesting and informative!
More knowledge here than any news or history channel by FAR! Great work💪
Thank you. This Appalachia girl, amateur geologist whose teeth were cut on the New and Gully Rivers, is obsessively enamored with the Ice Age Floods here in the Pacific Northwest. You have added appreciably to my understanding to that which I love.
I love this, I eat it up like candy.
Wow, strap yourselves in, you're going for a doozy of a ride. This should be most interesting.
.
Floodwater in the Willamette Valley moved much slower than the water flowing past Portland, and the water stayed in the Willamette Valley until the water passed Portland. This caused sediment to drop to the valley floor, making the valley higher. Cities in the Willamette Valley were buried rather than destroyed. Cities far older than 11 thousand years have been found all over the world, and there is no reason to assume that there are not buried ancient cities in the Willamette Valley. There is no reason to assume that people have not made tunnels down to ancient cities. Since there were many floods, there is no reason to assume that there are not cities stacked on top of each other.
I can only re-iterate what others have said below, but Nick, look after those knees and hips. Walk softly my friend. Pete from the Isle of Wight.
Thanks Pete. Got both knees replaced in 2017. Hello from America.
Is the fertile Willamette Valley due to flood deposits?
Great explanations for the landscapes around us.
+dadatschool
Yes, a big reason. Thanks.
These are really interesting videos. I learn something new every time I watch one. Thanks. I always thought Washington State was boring...but wait! I can't wait to learn more.
Lol we have rainforests, grasslands, mountains, beaches, deserts, etc in Washington
Great video! I assume the earth has the same amount of water today as it did back then since we don’t loose materials to space. Where is all that water (ice) now?
i learned an amazing amount from this
and... I saw some breathtaking (and having seen the explanations) fascinating landscapes
I swear.....if Nick had been my teacher/teachers in High School, learning would have been such a pleasure!! I feel cheated. Bravo, Nick!! Keep up the good teaching!! 💕💕
AGREE !! If Geology was a HS Course it would have changed my
Career ...and Life !! !! ✅
Have you ever heard of noah and the flood it was a catastrophic event about 4000 plus years ago
On the Tammany bar part of your video bout midway through you forgot to mention that the Missoula floods didn't just take one route to get down the Columbia river system. In fact some of it came down the Clark Fork, some down the Spokane River and across what is now the Rathdrum Prairie with the aquifer beneath it, and some came down the Palouse river and helped to form Palouse falls, that part of the floods hit a bluff across the Snake river from the mouth of the Palouse and backed up into Lewiston Idaho over 600 feet in depth. that is what caused the deposits you see presently in the Tammany bar. Plus I live less than a mile or two north of said Tammany bar. I learned this stuff in school. So please update.
I want to meet this dude. He is awesome. lol
Come visit.
I rewatch your videos on this subject repeatedly. It is so interesting to me.
How does the ice keep growing and lake missoula is filling up at the same time
Well presented interesting and informative. AND YOU HAVE A LOYAL AND APPRECIATIVE AND WELL DESERVED FANBASE i m sure if more yankee kids and young adults had you for a teacher or professor they wouldn t seem so arrogant and ignorant to thr rest of the world. Keep them out of the army as long as you can
I've a piece well several pieces of petrified coral, I think anyway
Beautiful country .I hope to visit it one day.
Make sure that you drop in for a visit in Ellensburg!
Are the videos about the animal species that used to live in these glacial lakes?
HELP. Can anyone help me locate the particularly specular canyon in the photo at 15:17 on the video. It blew my mind. Any help would be appreciated...PeaceOrElse
@@bradthompson5383 thank you. I will be respectful.
Great videos! Very informative.
Where in Lewiston can you see the layers of basalt, Bonneville, and Lewiston? I want to see IRL!
Thank you for teaching freely. I find all of this so fascinating!
im really sad that this channel hasn't had an upload in 7 years :(
you’re doing a great thing here! Quality education
Thanks a nice comment. Thank you!
Thanks so much. I visited Dry Falls and Grand Coulee this weekend, having never previously known of these floods. Fascinating stuff!
Thanks Matt. Pretty wild stuff, right?
Re-watching, and in wonderment anew. We are so lucky to have these. 💗
What! No red bow tie? The maps and scenery help me grasp the full story of the ice age forces that created such beautiful landscapes. The info on the Bonneville flood is fascinating as well. I assume the causes of hot spots are not fully known? Is the hot spot moving under the plate or is the plate moving over the hot spot?
I thank you for such a well made and informative lectures.
Thanks for the comments, Mike. Hot spots still a hot topic in geology. Ha, ha. Causes of hot spots still being debated...and some now saying they're not a fixed as previously believed. That's why we were kinda vague in the video.
imagine the sound that ice dam breaking and flooding would have sounded like
Thank you, Nick for this very informative video. I grew up in The Dalles Oregon and now have a new appreciation for the terrain of eastern Oregon and Washington. (I don't live there now)
Great work!!! Keep it up.
Thanks Mark!!!
Why are the sedimentary layers of the Missoula floods so uniform in width?
Good question. In general, they get thinner as you go up....but still....there is still mystery about what the layers mean.
I love these so so much !!!
Thank you
Cool Beans
Loved it, thank you ......... 16 minutes well spent.
Nice to hear. Thanks.
Lifetime PNW resident and since I've learned about them a few years ago I've claimed. "If I had a 1 trip time machine I want to go see a Missoula flood." Watching the huge ice dam break and release a torrent. Then going down to see so much water rip through the Columbia River gorge while standing on the top of those cliffs/plateaus would be so amazing. I didn't know of the Bonneville flood until this video just now and that sounds wild too. RIP to the native peoples and animals that were caught unawares by them though. Must have been catastrophic.
I harbor the exact same desire. Man, would that be something to see!! I live in Oregon and marvel at the Columbia River gorge every time I'm there.
The volume of water is too big for an ice dam 2 miles across 2 miles deep 550bar pressure at the bottom. The water would find a way through far before it built up to that pressure ask dam experts.
Under that pressure even a tiny cracks would quickly be eroded into a natural spillway is very questionable. And the dam couldn't have been smaller because of the height the glacial erratics on the valley edges but I guess the dates of the sediment will reveal the truth...
Dam "experts"???. You wouldn't happen to be pushing that 'global flood' nonsense are you?? Just curious.
@@bradthompson5383 I think he has been listening to Randall Carlson and is just repeating what he says.
Randall doesn't seem to understand glaciers are like bulldozers pushing masses of rock and earth and they don't just form in place.
Shared this with family in an email. Got a response from at least one family member who specifically mentioned 'thanks' for sharing this video. This is a well-made video. Could tell it was well thought-out and planned!
Several years ago I was fortunate to view a Patrick Stewart narrated doc about the scrublands that you just featured, described on the Science, Discovery, or Nat Geo channel. Would like to view it again. Years ago when I crossed the Missouri River @ Mobridge, SD, facing West, I had something of an existential experience. Thank you for yours, also.
As a fan of the Lewis and Clark saga, I love to see so many places that are familiar to me. Imagine being the first Americans to see this landscape..!
Fabulous presentation! As a Pennsylvania boy, I sure wish I had a deeper understanding of all that I was seeing while camping out that way many years ago.
Excellent short video.
So much that my geology professor at University didn't tell me back in 1966. I was always fascinated by all things ancient, but I ended up being a classically trained musician. Go with your strengths, but never lose interest in your passions! It will make life forever new and fascinating, even when you're old and worn down.
I Give my gratitude to this geologist for making this video.
pov youre in 7th grade

Oh, so jealous that Washington has you...sigh. You bring geology to life. --- A fan from SE Oregon.
I LOVE THIS VIDEO👍👍👍👍
Thanks for a great vid!! Wonder what sort of trigger was the cause for the floods in the highlands of Peru and Egypt. Please, do you have any theories about those?
Such an interesting topic! Why isnt this information mainstream?
Good question!
Yes. Thank you. They are wonderful. So much to learn!
J harlen bretz and j t pardee would be proud to have you as a colleague
Oh, in one vlog a display of the basalt floods, and the cracks they emanated from, with different estimates how long each flood may have lasted, how long to cover the area it did, how long to cover the "300 miles to the ocean"...estimates ranged from seven days to many years...seven days!...9/18/21, I'm watching the Iceland lava flows with this mystery "how does it stay molten" in mind!...oh, another thing, the glacial dam of Lake Missoula, breaching and growing back "maybe hundreds of times"...I dunno...can't imagine it!😃oh...this helps:9/19/2005 David Alt NOVA Inside Giant Glacial Lake Missoula😃
Even after 9 years, this is still really good stuff. I have seen a lot of Nick's more detailed class videos on aspects of the geology of the Pacific Northwest, but these 2 minute geology pieces are still some of the best entry level videos out there.
Thanks, Nick et al, for producing high quality long lasting material.
Awesome 👏 Love it
Well played sir, thank you from Vancity 🇨🇦!
Great videos, I have always been fascinated in Earth Sciences and kinda see it as a detective crime scene investigation, in meticulously putting the pieces of events in time together to show the current picture of the landscape.
Doug K Thanks Doug. Yes, we are detectives. We need patience as the clues are gathered over the years. Not an instant gratification game!
***** Such is the nature of science. Building new hypotheses on current knowledge, self correcting and never ending.
Thank you 🙏
After watching several of the video's, I see many of the same types of features at other sites in the West. How can I get you to look at other areas to confirm my observations???
Thank you!
Really well done. Informative and well-organized.
Very informative for this geology buff newly arrived in Hayden, ID from San Diego. Had I seen a video like this when I was in high school (in the 1960s) or early college I would have continued as a geology major. Instead I became a math major with grad school in computer science and worked on military aircraft systems. But on my daily walks I see the basalts, the Belt group limestones, and I'm always on the look out for erratics. Thanks for making the effort to do these videos.
Welcome to the Northwest. Thanks for watching these.
You are so lucky to have escaped S.D. for such greener pastures. My guess is you don't miss the 5 & 805 merge, The lovely congestion during your commute on either the 52, 15, 56 0r 78.....If only I could be so lucky.
Having grown up on the Columbia River and seeing a program about Mr. Bretz, I've been fascinated by the geology of this amazing landscape. Thank you for adding to this knowledge in a most interesting way. You clearly love what you do.
Thanks Carol. Yes, it is interesting material for many of us.
I've always wondered if the weight of the continental glaciers would have had any effect on deforming the crust and maybe any relationship to the vast amount of volcanic activity ?
Definitely an issue with crust loading. This was a major theme with an Ice Age Floods field trip led by Vic Baker recently. Work yet to be done factoring in the amount of isostatic rebound. Good question. No known effect on volcanism.
*****
Thanks for the reply. I was just reading about subduction zones and the Cascades, very cool stuff.
We get tremors in southern Ontario because the bedrock is still rebounding from the weight of the glaciers.
You do such a good way of describing this complicated history. Thank you. I admire all the people who have studied and recorded this .
We need one of these guys for every geologic province in America 😆
Great video presentation.
Thanks Donald!
Oh my!
Wow.
Mr. Zentner, this was, and is, an excellent video. A very great job indeed.
Sir, thank you very much, for your hard work in the production of this great presentation.
Thanks Oscar. Tom Foster at hugefloods.com deserves all of the credit for these programs.
