Grand Coulee - Ice Age Floods - New Thoughts

[@samhklm]

You know with content like this television is dead. Thank you Nick Zentner.

[@swirvinbirds1971]

Seriously. I don't watch TV anymore except to catch live sports. There is just too much good content available here and elsewhere.

[@judgegixxer]

Agreed, I canceled my cable last year.

[@richinoable]

Summer of '61 and I'd just finished 1st grade at North Hill Elementary in Seattle. Dad was inspired to take the family's yearly vacation at Grand Coulee Dam and Lake Roosevelt. En route in our '56 green-and-white 4-door Ford Faiirlane, I stared in complete awe at the lunar landscape that was the coulee. I've been fascinated with Eastern Washington's geological history ever since that magic summer. Watching Nick as he crunches over the trails and 'round sweetly-scented sage bushes ... it's like watching Dick Proenneke build a cabin in the Alaskan wilderness: you can actually feel your blood pressure go down and your sense of well-being and purpose rise to the surface. Thank you Mr. Zentner ❤️

[@machinestool]

Thanks for sharing these great expeditions for us at home. That's the most fascinating landscape I've seen.

[@phillipdavis3316]

Awesome as always. Thank you Nick

[@phillipgregory9021]

nick....you are an excellent teacher!!!! kudos!!!! thank you pg

[@stevestackpole4042]

Wow! Love this idea! A whole new wrinkle to this big story. Keep going with this. Thanks Nick, your excitement is infectious.

[@FerrickOxhide]

Love it! I camped near "small" Dry Falls. Whole area is fascinating.

[@ChuckHickl]

This popped up in my feed based on my enjoying geography videos and I will tell you it is one of the best videos I have watched regarding such a specific topic like this. Well done and those are some lucky students.

[@marksinger3067]

Nick is still the brick.. The morning java and your video is waking me up..

[@lorenmorelli9249]

Excellent!! You have a true gift and unique ability when it comes to the conveyance of knowledge... Thanks!! 🤠

[@SuperOlds88]

Wish I would have known all this 50 years ago when I hunted and fished all over eastern Washington. I always was impressed with the landscape especially at Banks Lake.

[@raymondkudlak7310]

Hello Nick, just landed on your channel today not having planned to do so! Fascinated with the revelations you are pursuing as I have been slowly consuming presentations on KZbin related to the Younger Dryas event and it’s effect on the North Carolina Basins and speculation as to a major Impact of a presumed Asteroid or Comet. A long time ago while on business trips in Oregon and Washington, I had little knowledge of the Scablands. So, I have now entered a stage in life where my investigative interest is solely for my edification and enjoyment. I will be viewing your several KZbin videos and related videos of others. I am not a true scientific minded person, having only a BS/BA in Marketing and Management earned in1966 at Fenn College which became Cleveland State Univ. In my final year. Your style and ability to link A to B to C to D has kept my attention in a subject not at all familiar. Thank you, looking forward to more knowledge of this subject from your perspective. Ray

[@rwnelson51]

Sitting on a Talus slope in the lower Coulee reading Bretz with the1947 illustrations -- just the best Nick!!! Humble Thanks!!!!!! Mammoth.....

[@williamasher9659]

Nick I want to thank you . I am a 55 year old Bozeman Mt based mule Geologist who has gained greatly from your hot mike self pep talks . I have made self talk a daily routine with great success . Your lessons have deep impact. God Bless you

[@Vickie-Bligh]

I love how science never stops investigating. I love that geologists are pushing the envelope of what we know. Thanks for the education, entertainment, and presentation of our beautiful state. You're the best, Nick.

[@murraystewartj]

Nick, I love your stuff. You are living proof that a true scientist doesn't get excited about what they do know, rather about what they don't. Enjoy your summer of discovery.

[@DonnaCsuti-ji2dd]

So well put.😊

[@Foxxorz]

Your content is endlessly fascinating, and really changes how I see the geology of the area I live in.

[@tgchism]

Refreshing to see someone so excited about work they been in for 30 + years!

[@quantumbitz3473]

Genuine teaching come from a clear focus. Thanks for the continued series; captivated by your good nature and ability. Your lecture class is fortunate. Cheers Nick.

[@DonnaCsuti-ji2dd]

Yes most interesting and thought provoking. Thank you. It makes sense to me that there could have been multiple cycles that are hard to detect but with newer ways to age rocks it may be possible to collect more samples from multiple layers in various locations to test and possibly solve your queries.

[@georgerisberg8830]

Great to observe and think along with you, Nick. Thank you for sharing this while you're still exploring the literature and the land. Correlation to Illinoian Glacial period?

[@denisee9966]

Listening to your videos is MY idea of a good time!

[@goldnlab]

Thank you for actually practicing science professor. I enjoy your content very much.

[@barrydysert2974]

You are giddy with excitement Nick! It is wonderful to gain a fresh perspective on a well worn topic. You have the eyes of a child seeing the world for the first time... again! Congratulations! It brings great joy to me to see You absolutely beaming with happiness. i love You 💜 and God bless 🙏 !:-)

[@Bassbari7889]

Thank you for you skill at bringing your knowledge to the masses.

[@patriciasmith7604]

I'm 82 and remember learning about gondwana land as a possibility when I was in grammar school. I was hooked! Your students are lucky to have such an enthusiastic and curious professor and I''ll be watching you in future.

[@dogcarman]

Since ME/CFS took over my life my days going walkabout were over. But through these videos you walk for me, Nick. Thank you. ❤

[@gagarinone]

Thanks for taking your time to record and share your knowledge. Greetings from Sweden.

[@percybyssheshelley8573]

The geology of the great state of Washington is absolutely fascinating. The strikingly dramatic structure of the coulee area and the mind-boggling timeline of the events contributing to its creation holds such fascination it's little wonder Prof. Zentner can't leave it alone.

[@derekcook3095]

Exciting stuff Nick! Looking forward to hearing more on this topic.

[@ImSarcasticOK]

im 22years old from norway. not really the guy in class who manages to learn quickly, you explain things very good and i learn from you. listening to a guy who actually has a passion for this is soo much fun. thank you for making these videos.

[@warpeace8891]

I am subscribed to about 90 youtube channels and my 12yr old son asked me.... 'if I could choose only one youtube channel which one would it be?' The first one that popped into my head was Nick Zentner. This video is another reason why.... an honestly, genuinely passionate look at one's surrounding. Just like humans have been doing from the first humans. Without agenda or bias you follow the evidence wherever it leads and give respectful credit to all involved. Thank you Nick for doing what you do and sharing it with us all.

[@MrJeffTrader]

Nick - your videos are incredible. Thank you for sharing your knowledge with us.

[@yukigatlin9358]

Oh WOW!😄 Nick, I'm very excited to keep track on your new developing thoughts on older maybe more significant Ice Age Floods from Spokane glaciations hundreds thousands years ago!!💫💗

[@dr.billschlosser7983]

Brilliant, Nick! Keep weaving this tapestry into a magnificent rug. It is now in your hands. We are all with you and waiting for the next chapter, or page :)

[@rayschoch5882]

I like the point Mark Earnest makes - this looks like another chapter in a developing story. I've been in this area so often via KZbin it's beginning to feel like home. If I lived in the Pacific Northwest I'd be out driving / stomping around looking at all the landforms, contours, rock types, etc. - the names of which I have not memorized, and can usually just barely pronounce. Fascinating stuff, and my thanks to Professors Bretz and Zentner. Keep it up!

[@Anne5440_]

Ray, I first moved to Washington in 1962 at age 13. Much of these decades I lived in Eastern Washington. From 92 to 2008 I had a side track to Kansas and Colorado. I moved back to the soap lake area in summer of 08. I decided one day to drive up the lower grand Coulee. When I got to Lenore lake I parked in the parking lot showing in this video. As I turned off the car it suddenly hit me and I said out loud "I'm home! ". I've always loved the dry falls area. I've been many times but never have had enough time there. So you are not alone in felling like it is home. BTW, the Coulee looks large in the video. But it is much larger than the video makes it seem. To stand in the bottom and try to imagine the water of even the Missoula floods above you is truly incomprehensible. I hope some day you can come see this state. It is amazing what is here.

[@Siletzia]

How exciting, another chapter to the developing story of ice age flooding in the PNW. These episodes continue to amaze. Thank you, Prof Nick, again.

[@russellbarndt6579]

Oh my, I so appreciate how humble you are and so willing to accept and learn new information. Really got my respect Mr.

[@lb8848]

Great story. Keep it going. We're with you, Nick.

[@richanway5204]

For us arm-chair Geologists who are always looking for new and exciting content, I say to you Mr. Nick that was 28 minutes of the best "on the edge of your seat" commentary you could have ever asked for. I salute you sir, and Thank You Dearly.

[@rogerwalker2242]

Dear Nick, I started watching you about 3 to 4 yrs ago. I didn't like school and could have cared less about geology. I'm now 60yrs old and absolutely love and am fascinated about this subject. Where were you back in the late 70s? You have a way of making learning fun!

[@DonnaCsuti-ji2dd]

Think of all the minds now stimulated and thinking about the questions together coming to various conclusions and through investigation and discussions helping others to come to some new and different conclusions . Really so exciting.

[@petrichor649]

Thanks Nick, I have developed an interest in these ancient floods and know more about this part of America's geology than my native Thames Valley.

[@louiscervantez1639]

You are never boring! This is exciting! Thanks to Sharon.

[@anniegooden5084]

I am traveling to Ellensburg to hunt for agates before heading to MT, ID, and OR to check out the local geology along my route and do some gem mining for my birthday month! Hopefully someday I will get to see one of your public events there in Ellensburg. I am an alumni from MSU Bozeman ('99) and you have revived my love of geology now that I am living in WA. I'm a huge fan!! 🤩

[@BirchOutdoors]

I was born and raised in Washington. Always had a proclivity for rocks, mountains, and geology in general. I've been to most of the places you make videos about and I love sharing what I learn with my family during those long eastern Washington drives. Appreciate all the thought and effort you put into illuminating us about the amazing geologic utopia that is Washington. Many thanks!

[@ionizer24]

Really enjoying your revelations. I always thought it was too simplistic to put all the erosion down to one glaciation event. Keep it up. You definitely are not boring!

[@efhalter]

Mind blown Nick and thanks so much. I'm about to spend 4 weeks in this area in June and July and have a Masters in Glacial Geology (not used much during my work life but now that I'm retired I'm getting back to it). I'm fascinated by this entire region after passing through it last summer and I so appreciate the work you're doing and service you're providing to put out these constantly evolving ideas. Keep the great work doing coming and maybe we'll run into each other :). The thought of another waterfall complex larger than Dry Falls boggles my mind!

[@RICDirector]

I love watching your brain fizz...and it is contagious. Thank you!

[@pauldickman4379]

Thank you Sharon, wherever and whoever you are, for finding that paper! Sent us all in an exciting direction.

[@richinoable]

The energy comes thru the KZbin somehow. It's like spooky action, at a distance, bringing excitement to those of us who remain entangled. Im glad the energy focuses on the geology, which my dad turned me on to. ( He was into Wyoming) Thanks!

[@guiart4728]

Good stuff and again, the difficulty of grasping the enormous passage of time in a geologic sense requires constant recalibration of our sense of the process. Thanks for recalibrating my brain this morning!!!❤

[@fredmunson8952]

Thank you Nick for the updates. I love this.

[@johnslater1460]

As a rather long in the tooth retired maths teacher in the UK, I love your posts. I used to grapple (physically!) with the geology of the Cuillins on the Isle of Skye and the Torridon mountains further north in Scotland and marvelled at what had happened there in the past.

[@davidcoleman757]

Greetings from the UK. These videos were so fascinating that I arm-twisted my brother into a road trip to the Scablands a week back. I didn't have much time in the States, but boy was it worth the drive. I've never seen a landscape like it, and your posts really helped bring the scene to life. The Dry Falls took my breath away. Oh, and those map illustrations in this video are fabulous. Thank you. I look forward to your future musings on how this marvelous landscape evolved.

[@RobertJohnsonmusic]

Prof. Z, your summation of the earlier, Spokane glaciation--described by J. Harlen Bretz ninety-nine years ago--is absolutely intriguing. Although I sat in virtually in your Geology 351 classes years ago, I now envy the current crop of students who are completing a term with concentration on your ice-ages flood stories. Thank you!

[@RobertJohnsonmusic]

Thank you kindly, Sir!

[@kc7brj]

Fantastic lesson! And it all fits...shaping our minds to fit the terrain.

[@ThisIsMe3699]

Nick. Thank you for your videos. I live in the east where red clay is everywhere. I see my home sitting on dry flood slurry. My home was built in the 70's and no grading was done. Just digging a little shows a lot of activity. So much small quartz everywhere.

[@Cherijo78]

Those caves are a great hike with kids! My kiddo loved exploring there! Those are neat revivals of literature! There is so much written down in old obscure books that gets lost. I ran across an out of print book about the old coal mining towns around the Carbon River near Mt Tahoma several years ago that had fascinating history. It was one of those 80s compilations with the crappy, black and white printed photos and everything that someone had taken the time to write down and put together, and while the small time publisher could still do another print run, there's a minimum amount and it's way beyond my personal ability to get a new copy. In the meantime, the old copies are wearing out in the libraries and getting lost. It just goes to show you that there's a lot of history and thought decaying in old out of print books on people's shelves and in libraries that needs preserving and to be more easily accessible in the modern information age! Thank you for those wonderful thoughts!

[@gregwarner3753]

Thank you for these presentations. My lady (deceased two years ago) and I became fascinated by these geological events. We did manage to visit Missoula, MT about five years ago. Unfortunately we did not continue West to the Scablands. Your videos help me realize what we missed. I do not have the energy for another PNW trip this Summer. I do, providing the doctors can figure out my anemia, plan on traveling to Nova Scotia and Newfoundland to observe the landscapes and geology of those places. Not to mention the food, music, whiskey, and women. That will be an interesting trip. Again, thank you for your work. GregW

[@kayafternoon9045]

Beautiful soft colors today

[@dharmadove]

Fantastic Professor ! Wish had you for my Geology studies when I went to UNCC in '77. Got a dual BS in Geology/Meteorology. We didn't study much west of th Mississippi, my teachers focused on the Appalachian geomorphological stratus. Being a spelunker I did my Senior Thesis on the Flint Ridge cave formation. That was before the Mammoth Cave extension. I am a big fan of JH Bretz. Had a original cooy of "Caves of Missouri", unfortunately gone now. I started reading it a a kid, my budding days of Cave explorations. '68, I was 12... Great stuff... Your videos have really taught me so much about PNW Geology. Maybe I should follow up and get my MS degree with your guidance. Keep it up this summer, lots for me to learn. 👍

[@greghelms4458]

Great content. Love your work and Myron Cooks work. Both of the areas you guys predominantly work in are extremely interesting to me.

You have inspired me to drag my disabled ass across this territory as a part of my bucket list and am completely fascinated by your studies.

[@tinkmarshino]

The most interesting thought is that I saw this coming for a long time.. you would talk (however shortly) on the floods that happened over a million years ago... even ask questions.. but always said that is for the field guys to figure out... all the time I saw you add a little more and a little more often.. and now here we are.. what fun! I am ready, willing and mostly able.. Carry on my friend.. I am rooting from the side lines..

Be careful to explain the word and that it has no possible cultural ramifications in todays world.

[@toughenupfluffy7294]

@@mpetersen6 The two words are spelled differently. The one that's an ethnic slang originated from the Hindi word kuli, which simply meant 'day laborer.' 'Coulee' comes from Old French. It meant 'to flow.'

I can no longer climb and kneel among the rocks and rivers and your explorations help me enjoy a quality of life a lot of my peers in their dotage often can't fathom!

Love your clear explanations and visual evidence of ice. I've noticed on some petroglyphs, that they were carved before the glacial striations and it was puzzling me. This puts the events in order. Thank You.

[@geenogee]

The Priest Rapids basalt layer lies on top of Dry Falls. This layer extends north to Banks Lake and east of Dry Falls across the coulee. This is the uppermost basalt layer. It seems a little unusual that this top layer was not eroded away in this location.

[@Utahdropout]

Nick. Wow...!! Very interesting. This whole period of geologic activity is just fascinating to me. I grew up in the Salt Lake Valley looking at the marks of the shorelines left by Lake Bonneville and wondering about the events that caused them. The way that and all the other ice age events in the western states would have been amazing to witness. I share your love of the search to uncover the sequence of events. Thanks for sharing.

[@genebohannon8820]

Thank you for loving the sharing of knowledge. I have few people who ever want to get into titillating conversations that aren't about sports or the feeble President.

Saw this as replay. Excellent--and most excellent sound image clarity on your new rig! Second listen to 25 May GSA Reno podcast. I went too. Offer a nudge: I've been to Penrose conf. Just like Amer Med Assn w/docs + their research. In hallways, all convivial and collab. Once in presentation hall, crickets and clams. For Aug Penrose, "obligation" is to be the moderator. Gentle but urgent insistence. Voice, knack for creating intelligent, accessible comfort bubbles for scientists to talk. Use the gift so many listeners here recognize. Besides, you have lots of history behind you.

Stoked on these new thoughts and theories from looking at old bibliography and research. It in parts reinforces Bretz's research, but also brings to light how the area might've looked like millions to even thousands of years ago. Cheers from Omak!

Thank you Nick for sharing and looking forward to your explorations in geology this summer. Cheers from Stanwood 🍻! Alex

[@boba9253]

It does not surprise me that Bretz realized the pre-wisconsin glacier(s) were more instrumental in the carving of the scablands. Being a midwesterner, Bretz was aware that the same phenomenon shaped the great plains and eastern landscapes, and very obviously in his home state of Illinois. I have long wondered where all of the outwash basalt was deposited, which should be enormous, if this happened during the last glacial cycle. Very good to hear, looking forward to more!

[@mpetersen6]

Of course depending on just much ice is built up into a glacial advance the more potential erosive power that melt water will have when the glacial advance ends and the interglacial begins. But that erosive power will depend on just how much water is impounded in glacial lakes that is then released in outburst floods. If the melt water is released in one continuous gradual glow I would expect the total erosion to be less. On another note. Just how much does sub glacial flow have to do either fast continental glaciers disappear. Do they erode as much as they melt?

[@daveisnothere]

I have wondered the same all while I was researching the Missoula and Bonneville Floods. The sheer volume of rock and dirt should be evident somewhere, but where? Some say it is off in the ocean, but looking at satellite views I'd expect to see a bulge of debris, but dont, so unless I missed it somewhere. I also wondered where the moraine went that would have formed where the ice stopped in the Clark River Valley. There are some hills there but no other evidence of a moraine. A moraine would have stopped a lot of the water from going under the ice, no one ever has mentioned it..... ever.

[@davidcooke8005]

There is a huge section just south of the coulee that fans out like a river delta for miles. Somewhere on KZbin is a video about it. I've driven through it, The whole area north of Ephrata and south of Soap Lake is one giant boulder field.

[@Anne5440_]

Thanks for starting with the hanging valleys. I've always wondered about those when I'm there. To me the lower Grand Coulee is the heart of this amazing state. I've always been uncomfortable about the Missoula floods being the whole story. As I've been with you on this floods story I've had a growing feeling that there is more and older story than Missoula. It began to start growing with Joel's first Waterville plateau channels video. The mild curiosity turned to how do I learn more when Skye Cooley talked about the deposit at the George gravel pit. His saying that deposit is from about 100k old lit the light bulb. So I for one am delighted that you are looking for more knowledge! This is making the story much more interesting. I am one who doesn't accept simple solutions. Yes it is a glaciation story but more than one glaciation has to be involved.
