Shawn Willsey is great and Jim O’ Connor was a total trooper in powering thru his head cold to present!! Tremendous show- Huge thanks to Jim, Shawn and Nick. Awesome geology!

Nick, Shawn and Jim = Dream team. Stream it and they will come.

I will be honest, when I saw the length of the video I had thoughts about maybe skipping this one. I am so glad that I didn’t. What a wonderful presentation of information by people who are so passionate about their profession. We are all richer for having the opportunity to learn from them.

What a hero Jim is!!! Thanks to Shawn and Jim!!!

even for the lay person with little training in geology, this subject overpowers the imagination. for anyone who has ever loved the landscapes of the pacific northwest, this series is some kind of hard-to-believe gift

Big fan of Shawn, glad you've connected with him.

What a great show. These just keep getting better & better. Hope Jim gets well soon.

Shawn, I knew today would go wonderfully for you. I'm glad you and your wife overcame all the technology issues. Thank you, Mrs Willsey, for saving the day and for the support you give Shawn'spassions! Jim, thanks for adding to the knowledge for us about the Bonneville Flood. I hope you feel better very soon. Nick, thanks for another wonderful lesson. As always, the teamwork of scientists and all the Zentnerds adds to understanding and chat.

Thank you Shawn, Jim and Nick.❤

Thank You Nick, Shawn, And Jim O'Conner!

I love Nick and Shawn Wilsey

What a treat, my two favorite Geologist channels in the same video! I am a big fan of both. I think about the Bonneville flood all the time but I live in Cache Valley and the ancient bath tub ring (shoreline) of Lake Bonneville is in my face every time I look out my back door.

Thank you especially to Jim who did the absolute most. His passion is awesome.

One of the things that grabbed many people’s attention about a Missoula flood was the computer graphics video created to give us a bit better idea of how the water going over the cliffs was way more than Niagara Falls. And it still did give it the height of about 350 feet the water was above the falls. I have never seen images of rushing water filled with the rocks and gravels like the Bonneville flood obviously had. Not even in scientific recreations on a small scale. Closet thing are landslides. Not the same thing. I think a computer graphics driven video of it would actually extremely mind blowing. Definitely help bring attention.

Wonderful collaboration for this presentation . I've watched Nick 's videos for several years and Shawn's videos for about 6 months. It was a pleasant surprise when I saw them together. I hope they plan more together. it would be icing on the "Red" velvet cake

Shawn Wiley fan checking in! Thanks for including us. So nice to see you guys collaborate.

Wow, I was just blown away by the information, ideas, and the great presentation by Shawn & Jim! Thank you Nick for sharing Shawn and Jim with all of us and thank you Shawn and Jim for sharing your knowledge, insight and passion with us Zentnerds!

Thanks for the great guests! And your sincere enthusiasm. Love the stories and insight you bring to our world. Amazing🎉

Finally made it through, after three sessions. I'm out of superlatives, but once again a wonderful episode. Amazing to hear Bretz's final written words on the topic. Thanks to Shawn and Jim both for going above and beyond. Thank you Nick for the huge amount of work putting all of this together, and for assembling a small group of other geologists willing to regularly help all of us on this journey.

“I don’t know how he manages this high wire act, but I can’t not look to the end!” Both Shawn and Jim were swinging for the fences…and delivered! Thanks Nick.

Tough guy! thank you, Jim O'Connor Guy loves what he does. All of you are passionate about your work, that is contagious. You got to love it. ALL stay safe

Jim is a real trooper to press on with his knowledge and enthusiasm for todays topic . Just started watching Shawn recently. I live in the Great Basin and have family in southern Idaho so visited many of the locations discussed in this presentation. The sessions just keep getting better as we work our way through the calendar. Thanks to Shawn, Jim and of course you Nick!

This is yet another splendid "4 dimensional adventure" in geology! Nick, Shawn and Jim thank you for providing us with your insights and findings from decades of work in the field. You really "make our days bright"!

Nick..🎉 This way of presenting information is extra ordinary. Your guests put the pieces together and the free flow format allows us to think along with you. Most people state facts and expect them to remember the facts. We're actually conceptualizing real time with you. You must have noticed it's become personal with some thousand people plus and today was incredible 1,800 + for 3 hour's???? You Win Nick!! 👏 The whole community from phone Nerds to Learned Men are realizing the greatness of what your doing and this is a blueprint! I was a Nick on rocks guy way back and then you Did Baja BC and I was hooked on the new understanding that these questions weren't finalized? It's news to Most people that everything is really still up in the air and there's exciting things to learn!! Your bringing that and I Salute!!!! Nick Zentner!!!!

Jim O - The "Rock" Star of Geology!

Nick and Shawn.. YT geo Legends! 😎😎

Finally got chance to watch this. So great to see Shawn Willsey on your channel. My fave geologist tubers on one show. The knowledge and passion is so super inspiring. Thanks chaps. 💚

Great to see this happening between two knowledgeable, gentle, yet passionate geoboys!!

Nick, thank you very much. It has been a great time.

Watching in replay and quality is great!

Cool cool cool. Namaste 🙏

Watched this one in replay, and glad I did. Thanks to you, Shawn and Jim! Also, thank you for reading Large's reinterpretation presentation to the group in Spokane. You really have to admire Bretz's dogged, analysis and his willingness to correct some of his prior interpretations of what he had originally seen. Generally, I don't think he tried to twist the field evidence to fit a predetermined point of view, but grew as a scientist and was willing to alter his position when it became necessary. I know others may disagree with that, but it takes a lot of fortitude to swim upstream, regardless. MHO! PEACE!

Thank you all for this wonderful collaboration. It was educational and inspiring. The insight into the history of the thinking and development of the science was fabulous. I’m really looking forward to the next episode. Can’t wait!

I am extatic on a 3 hr video. Thankyou for your time.

Came here from Shawn's channel, will stay for your content. I'm generally not a big fan of super long videos, but this was great. I love it when scientists are not just so obviously passionate about their work, but also willing to share their knowledge for free, in a way that laypeople can understand. Thank you 🙏

Wow! This may be my most favorite episode - but I keep saying that so who knows?!?! I love them all! A special thanks to both Jim and Shawn! Thanks for contributing to our ongoing learning and ever-lasting curiosity! Jim - I hope you feel better rapidly! I SO appreciate you making today work. Shawn - I'm adding several Idaho field trips to my bucket list! My friends who live in Idaho will be super validated - they've been telling me for years!

Thank you and your fellow presenters for this interesting and informative presentation. A week ago, I had never heard of the Missoula floods. Clearly a lot of work and effort has gone into this presentation. Thank you for bringing this light to our knowledge.

Gah! So excited to see my 2 favorite KZfaq teachers!

I NEVER get to do Sunday live, but I'm looking forward to this one. I started watching Shawn Willsey after you mentioned him one time and I enjoy both your style and his. I wouldn't WANT to watch a bunch of channels that all do the same thing the same way. You have your style, Shawn has his, Myron Cook has his style, and GeologyHub is totally different from any of you long-form people. All great to watch for us geology fans. :D

3+ hours doesn't scare me! Love love it!

WOW! Shawn Willsey provided some links I was looking for one the one time Boniville Flood. Thank you Nick, thank you Shawn.

Yes indeed, Thank You!!!!!!!!!!!!!!!!

i watch and love both of you two's podcasts. i never knew geology was so interesting. thank you 2 for exposing me to this fascinating science.

Nick, you knew, you knew all along!! WE all had to get there, least that was your hope!!💞💗💫😄Thank you Shawn for describing Bonneville Flood!! Thank you so much for braving your illness to speak to us in the area showing the differences in the type of floods in hydrology, Jim!! I hope more younger geologists will join you guys!!😊💗💫

Thanks for shedding the light! Another great story for the interested and river runners!

i would love to see more of Shawn and Nick, they are great teachers.

This was a complete and thorough blast! (It took this long for me to carve out time to watch it all, traveling and with family.) Shaking my head: epic collaboration, again, showing the intense commitment of teachers/scientists to discover, compile, share and educate. And you all are such fun, too. Simple thanks don't cover how grateful I feel but will have to do. Thank you, Shawn! Thank you, Jim, and I hope you feel well soon. And thank you, Nick, craftsman, and without whom none of this would be a thing. Geez.

Great job again. It is a privilege to hear from these various geologists.

Hi in replay from Sydney Australia

I knew that Craters of the Moon was going to be shown to be the prime mover in the creation of everything!!!😀

Just wanted to comment on the Jon Shellenberger episode before the Jon Shellenberger episode. Rather than dry statistics and measurements, this one will "humanize" the ice age through the lens of belief systems prevalent at the time. I salute Nick for including this departure and look forward to this installment.

Poor Jim what a trooper. Lovely guy. Enjoyed this immensely! Thank you. ❤

Nice to see such an in-depth discussion of Bonneville. My 1984 MS Thesis at Lewiston included impressive outcrops of Bonneville gravels overlain by slack water rhythmites from Missoula flood waters moving up drainage in the Snake. I always used to try to imagine the Bonneville flood waters screaming down the Snake and hitting the Lewiston fault scarp then continuing down the Snake. Must have been a sight!

Many thanks to Shawn and Jim (and of course Nick). After many years of not knowing how all the pieces fit together, I finally understand what happened with the Bonneville Flood. Years ago I was on the Snake below Hells Canyon and looked up to one of those big gravel bars and thought that was one hell of a flood flow. Now I know why.

I was only able to catch bits of this stream when live but I'm very much enjoying watching this in replay, such a great series. Last July we did a family road trip to Wyoming from western Washington. I was amazed by the different landscapes and indeed visited Shoshone falls park. It's fantastic to learn more about these floods as I only just recently discovered the world of geology and Nick Zenter just in time to catch the beginning of this series. Thank you so much for your work Nick and all those in this community who've contributed to this movement. Sad that the series is near its end but at least they will live on in replay format and on the site. One can hope for bonus episodes but my goodness it's been a great ride.

Thanks Nick, Shawn, Jim & Dog. Good stuff!

WOW, amazing show here!!!

The two of you work really well together. I follow both of you so this was a real treat.

I'm the same way as Jim (?) I admire that he can keep going not sure I could keep talking! Bless you both if I had teachers like you and your guest I may have loved becoming a teacher. My Prayers to all. Barbara Dick ❤

I was helping at the homeless shelter today Just finished at 3:00 Pm central standard time ..Wow over 3 hr I got something else today Yeah the basketball game is over now .

Glad to see more about the Bonneville flood. Two of my favorite geologists here (3rd is Myron Cook). I did not know Jim before. His story about Mr. Malde was inspiring. Thanks to all.

I've lived in the path of the Bonneville flood, or at least the periphery, most of my life. Also lived on the Rathdrum prairie to bring to mind lake Missoula. This topic is fascinating The lava flows near Shelley and IF are worth many a story to new arrivals. If they go to Craters they would have their minds blown. Thanks for what you do.

Fantastic recording! Nick and Shawn, you guys do such a great job of making geology accessible to the general public--can't believe how much time you each spend on doing so! It's also clear you're supported by your wives in your efforts--kudos to your wife, Shawn, for all the help! Jim, wow, what commitment to spend time with public when you're under the weather! I need to make a multi-day geology trip to Washington and Idaho! Do you guys lead Elder Hostels!?

I wish I'd done some Geology 47 years ago. It might have given me a field trip. Can't beat the fresh air.

The Return of The Ring - last 4 hours … This presentation was just as enjoyable … THANKS Jim, THANKS Shawn, THANKS Nick.

Length of show is not important. Actually, I think we are getting more 'meat' from the guests with the longer shows. If needed for the replay, easy to pause and come back in a bit. Thanks for a fantastic show with Shawn and Jim. Both of whom I have started watching all their presentations since you introduced us to them.

Watching in replay... gratitude! Epic series. Also, I am entirely moved and very much looking forward to Thursday with Jon S. Thank you, Professor Ned!🙌🏻

Well done…look forward to the next episode.

Nick, you made the comment about how both of you are generating interest in the area. That’s so true. Living in Senoia. GA even my wife is excited about traveling there to visit many of the spots about which both you and Shawn have educated me. Thanks to both of you for such an interesting topic to spend time during my retirement. I should have majored in geology. Who knew?

Great stuff shawn. Impressive erosion profile estimation at Red Rock Pass. Lahontan; NV Lakes too....

Wow!

So sad I couldn't watch the whole thing live. Finally managed to complete it Tuesday night. It was a fantastic effort on the part of all involved. This is an example of the promise of the Internet being fulfilled.

A scathingly brilliant presentation. As we have lived in Idaho 40+ years, we have woefully missed all this evidence, practically in our “backyard”! First: * living in Logan (USU) had no clue about the historical events, * now living 1 hour from Hell’s Canyon (seems we need to plan a raft trip downstream). *Our son lived in Lewiston (LCSC), must plan a road trip to see Tammany Bar * must revisit Centennial Park, Shoshone Falls, “scablands” East of Twin…. Wow… just WOW! Thanks for all you geologists do to share your stories!

I just managed to catch up on the whole series so far. I’m waiting with bated breath for the next instalment. I’m enjoying the education.

Thank you, Shawn. Thank you, Nick. So much new info for this Georgia girl.

I recall reading about the Bear River diversion on roadside highway signs. Not sure, but I traveled through this area some time back - many times.

Ooftah. Oh yah, let's keep it goin' - you bet ! ❤

Good thing it was a windy rainy somewhat miserable day here in central California, my wife and I not only made it all the way through this presentation but followed up with the "Perils of Noraly"! Those Missoula deposits on top of the Bonneville deposits sort of kills the Blue Mega Flood story, unless the Bonneville ages are way off. Red for the win!

Heading down to Salt Lake City from Boise on our way to Texas to see the 2024 eclipse. Can't wait to regale the wife with my new found knowledge. Thanks guys.

Haha, I just noticed Shawn's shirt, love it!

Shawn you are right you have to get the story onto people’s mental map. I learned this when I was promoting Boone NC as a tourist destination. First I had to help them create a mental map before they could realize where our town was.

So, the Bretz/Large Library now resides in Ellensburg, Wa.? Great work Team Zentner!

My other favorite Geologist ❤

We traveled through Twin Falls and camped at Craters of the Moon when we drove from central Nevada to Montana. So good to re-view that country from a geological perspective.

Deerfield, NH

Nick, thank you again and again. I treat these presentations as my personal mentor sessions about a great part of Washington, USA. With so many unexplored geology phenomenon in Australia, I look forward to some of your Australian colleagues copying your style and range of research.

Get Well, soon, Nick, after Your fall, at 'The Blade'.

I've wondered how to quantify the force of these huge floods. (I've rafted the Snake-class 5) "Huge potholes indicate Class 22 whitewater rapids". Thanks Shawn!

Do all geologists have a great sense of humor or just the the crowd nick runs with?😂

Pops out the chat just like a boss There ain't no ads, there ain't no cost Don't like the loess, then that's your loss A rolling stone gathers no moss Sorry, Patrick, but Nick's the host It's not his style, he'd never boast From the craton down to the coast Geology, he shares the most His fame's worldwide, his fans the best Net detectives, they never rest Until the Zentnerds have met success They measure up, they've stood the test Like Vinman's bread, they're number one Retrieve rock hammers too long gone They unearth letters by the ton Restore old photos most would shun Nick merely asks, they get it done Find Bretz field notes for everyone Generousness flows from the top Let's hope Nick's streams don't ever stop!

Nick I hope your better half enjoyed her day at the Seattle Art museum. I was an inspector on that job. So I know it would be safe in an earthquake.

Really enjoyed this episode. It is proving difficult for me to make these live these days, especially when they run very long, but I enjoy watching the reply in pieces on my own time, nonetheless. I'm sure you've already looked up whether Bretz mentions anything about Tammany Bar in the '69 paper, but in case you haven't yet, check out page 531: "A gravel deposit in the valley of the Snake a few miles south of Lewiston, built across the mouth of Tammany Creek Valley, is certainly a great river bar made under very exceptional conditions. In the light of present data, it may be assigned either to a scabland flood's backwash or to a northbound Bonneville flood emerging from the Snake Canyon south of Lewiston."

❤❤❤❤❤❤❤❤

If from Missoula or not there were multiple post ice age floods in the area of the most recent Missoula flood. The Bonneville would be going through what remained of these floods, and might mix with that which could be similar to the Missoula material, which would make it hard to distinguish the further you got into that stuff. Have they done deep cores to see if there is any evidence of floods in the area from earlier ice ages?

Thanks guys! If anything, Ghostbusters taught me you never cross the beams. Well here we are, beams crossed...

I’ll have what Nick is having!!

I really enjoyed this video, the topic, and the guests! I follow Shawn on KZfaq as well ❤

I didn't realize any of those rivers coming out of Central Idaho made it anywhere but down into the open fissures of the Snake River Plain ?

Tammany Bar is a pretty great out crop. I assume the paleo Salmon River outwash gravels are underneath & older, but not sure of outcrop or how we know that. So if Bonneville is ~17K, ALL the Missoula backwash flow & settling events reaching Lewiston are younger.

Science is most effective through collaboration, not competition. I still think there must have been some gouging of the land prior to late Wisconsin because three major glacial epochs preceded it. I'm wavering on the " Bigger Older, Younger Weaker" concept, though. There was a lot of water saturating North America after the last retreat. The Missoula and Bonneville floods and Lake Agassiz to the east of the Rockies attest.
