Bridge of the Gods Landslide

CWU's Nick Zentner presents 'Bridge of the Gods Landslide' - the 23rd talk in his ongoing Downtown Geology Lecture Series. Recorded at Hall Holmes Center on March 14, 2018 in Ellensburg, Washington, USA. www.nickzentner.com

[@mikelewellen4195]

So awhile back i wanted to learn to flint knap, which lead to learning about clovis people, which lead to videos about their possible origins, which lead to videos about the ice free corridor, which lead to videos about ice age floods and now I'm on lecture number two of yours, it's the deepest youtube wormhole I've fallen into to date, I'm glad I'm here. Thanks for all the history.

[@Ellensburg44]

Memorable comment, Mike. Great!

[@valoriel4464]

Mike, sounds like a wonderful journey. Inspirational

[@TheHelghast1138]

These are the best kind of wormholes

[@unibomberbear6708]

It lead me all the way to "Symbols of an Alien Sky" Documentary, and the realization that there was no Clovis people , and History ain't what we thought , at all. then to Immanuel Velikovsky , and then off Planet to the very formation of the solar system , or the car wreck of a solar system we inhabit. And that's where I am now after three yrs.

[@staceyhart9746]

Got any boring lectures to recommend? 😉

[@warriorbridetv7496]

I did the same thing!

[@paulrandig]

I am watching your lectures in Austria. Our Geology is so different from that of the Pacific Northwest. But after your lectures various things happened: I start feeling connected to a part of the world I have never been to. I start seeing our own Geology in a different way (and the Alps have some pretty awesome geology). I start asking myself questions in a scientific way when I am dealing with the unknown: What do I know? What do others know? Where is the evidence? What is theory, what are the facts? I try to see the story that connects all those dots of knowledge.

[@letsgoblue9596]

And I was Born in Ireland, but grew up in North Germany, Ireland had mountains and cliffs to spare, some of which I still go and glide of off. North Germany is kinda flat, with some hills, lots of swamps, and rivers.

That's a meaningful comment, Kenneth, since that's exactly what I'm trying to do with these lectures. Thank you.

Kenneth- you could always contact the universities up that way- I would be very interested in that area, as it seems to be the focal point for the Younger Dryas Impact Hypothesis

[@waynerainey2606]

I don't know if Nick reads this or not but I would like to thank him for his wonderful videos as the information and the way he provides it is a boon to the student and teacher alike. My students love the content and the way you present it. Most all of my students want to know what and when I will be screening the next video by you and which one. Now get this.... they always watch your video a couple of times before I show it in class so they can ask questions. I've never had students pushing the boundaries of their own curriculum before your videos. I've also started doing my own version of roadside Geology in the form of weekend field trips, their parents love it too !!!. Because they are High school students these field studies have to take place on weekends and with their parent(s) present. As I said the parents love it and so do my students. I have also received letters from 3 of the parents saying how participating in their children's educations has resulted in them becoming more involved in their child's lives once more and let's face it Geology is just cool. Please keep the awesome content coming, you make my job easier and help me define my curriculum each quarter ..... cheers!

[@Ellensburg44]

Memorable email, Wayne. Thank you! Nice to hear that our programs are helping. Great to hear that you are teaching geology so effectively. Congrats.

[@beenaplumber8379]

I've just discovered this series, and as a teacher myself, I am really impressed, though not surprised, to hear of this response in your students, and I appreciate what a remarkable phenomenon that is! How wonderful to find a tool that provokes so much self-driven learning and enthusiasm, even if the "tool" is the recorded work of someone else. (But isn't that really what a textbook is?) I'm an (early) retired neuroscientist, I have taught at the university level and now part-time at a middle school, and I confess, I watch Nick's videos more out of interest in becoming a better teacher. The geology is fascinating, but his technique is unmatched, and I'm taking notes! But now I am certainly engaged in many of the mysteries he presents. Correlation is not causation, but the Bridge of the Gods landslide and the 1456 quake as a putative cause seems to be a fantastic (if not blatantly obvious) hypothesis, at least worthy of a hypothesis paper (including, I'd hope, the "amateur" with the email that got it all rolling as a co-author).

[@TheHelghast1138]

As a student, I love to hear about wonderful teachers like yourself, stay awesome 😎

[@graham2631]

Thats great to hear as im over 50 l didn't have that luxury in school. It's now that im taking advantage of the amazing amount of information at ones finger tips. Its good to hear kids are using this important resource.

[@djloften]

I think it's great that your education of your students is so through, as a senior now I wish my teachers had taught the way you Gentlemen do, I had to slug it out until I got to University, to cross paths with such a prof. he was the one that posed the question can you see yourself in a classroom for another 6 years, I was going for a History Ph.D. I decided to take a high paying but a mindless job, as a shipyard labourer it paid well and I did retire at 50, know I dig for any information to expand my knowledge

[@josephpettus5068]

We should give Nick the graduatud and appreciation he deserves. There are very few people with the passion for teaching that he has. He has made the most complicated subjects understandable while keeping your attention and not just quoting what is written in a book but combining that with factual info that paints the picture that creates in our minds. That picture is differant for every one and if everyone were to put that picture on canvas and from one to another you would see the same thing and thats hard to accomplish.. The world needs more teachers with his passion .

[@Ellensburg44]

Thanks Joseph. I appreciate you taking the time to write. There a many, many good teachers out there, but most don't record themselves and post online.

[@cuscof2]

A note about salmon being able to ascend the rapids or not; it's a myth that salmon always go back to the river where they were hatched. They will **TRY** to do so, but if they can't make it they'll lay their eggs wherever they find an appropriate stream bed. Also, a certain percentage of salmon will always get lost, which is how new rivers get populated. If salmon couldn't get into the upper Colombia for a few years or a few centuries it's not an issue. As soon as the waterway was navigable to them they would have repopulated the river again.

[@r0cketplumber]

Yes, there's a reason instinct and genetics are a bit sloppy, to deal with natural variation. Salmon fisheries have been established in rivers in Chile and Argentina where they never were before, by bringing in smolts from the Columbia River. They have spread on their own to other rivers than the original release points. This new fishery can exploit the vast krill population of the SE Pacific Ocean, largely untapped since whaling wiped out most of the baleen whales in the 19th century.

[@ruthannadamsky9728]

I absolutely love the idea of geologists eagerly emailing back and forth, with facts and theories, cross checking information and building up scenarios for geologic events.

[@animistchannel2983]

Thank you so much for a wonderful lecture series. I particularly like how you show the transparency of the scientific process as it evolves, comparing sources and possibilities at various levels of confidence. Your spontaneity/humor while addressing what could be "dry" topics is also much appreciated! I'm also interested in the effects of the drainage changes of Lake Agassiz (relating to Younger Dryas and extinction/climate events) and how this affected various regions and the whole world. Sources suggest that sometimes it switched to drain through the Columbia River Valley. While the final, most catastrophic drainage was into Hudson Bay, I would also love to hear your take on how earlier episodes affected your region and others. It's a good example of the distant yet deep interconnections of our world. May your good work continue, and the Norns smile upon your endeavors :)

I have been enjoying these lectures from my place in SE Australis, on what passes for 'geologiclly active' down here. It was once of course and you can walk along the beach and find 'frozen' pools of boiling lave, and the hills about were all active volcanoes between 130 and 18 mill. years ago. Mr Zentner is quite rivetting in his presentations and has sent me off on another course entirely in my 77th year. Thank you very much Jeff Cole.

[@JB-gw8ee]

This guy is great. I've watched several hours of his lectures. I'm from Oregon and studied a fair amount of PNW geology years ago. So I'm pretty familiar with most of these places and topics and really enjoy hearing these great stories. And some I didn't really know and love to learn about. Now I live in the Sierra Nevadas and the rocks and geology are all pretty different. No volcanoes or exotic terranes around here. Figure I am sitting on a giant granite batholith. And I'm actually surprised how many earthquakes we get.

What a WONDERFUL presentation. I became interested in the Bridge of the Gods back in 1971 after reading the book "The High Adventure of Eric Ryback". He detailed (as best a 18 year old can) the geology leading to and from the "current bridge" on his trek of the Pacific Crest Trail. That got the attention of this "then young" California backpacker. I had always wondered how the trail could be so steep on one side of the bridge, but much gentler on the other, and why the geology appeared to be so different. Thank you for making this video available. I am only sorry that it took me so long to find it.

The island in the river below the Mosier Rest Stop has a tall marker on it. That is Balch's grave and memorial. He asked to be buried amongst his friends, the Native Tribes of the Columbia. That island was much longer before Bonneville was built. It was the major burial site of the Native Americans in the area. Most of those bodies were removed and buried in a mass grave. The mass grave is on the Washington side across from The Dalles. Driving toward The Dalles, the grave is on your left as you head toward the bridge to cross the Columbia. Thank you for such fantastic information about my favorite places on earth!!

These are just so great. I was surprised that the lake could have filled in so short a time! I thought for sure it would be a couple of years. I'm also amused by the dude filming him in the front row there, waving back and forth. XD

Well, just killed another hour. Very interesting, I’d heard to the landslide before but this is a comprehensive video. Thanks again!

Nice comment. Thanks!

I was born in the early '50s, and for 20 years lived downstream about a hundred miles from this location, and traveled there a few times to see Bonneville Dam and the locks. It seems laughable today that back then there was some people who still believed in the Stone Arch Story. I, as well as everyone, had no clue this stuff had occurred, but not as much time and money was spent on studying it then and so everything was just a theory without enough evidence to prove. This sort of "education" on YT is pretty cool. He's a true scientist bc he's willing to thoughtfully consider the possibility a theory he doesn't like could be real. He doesn't rely on preconceived notions or "feelings"; only evidence.

Fascinating! I have spent many weeks in this area for work and never fully understood the story. Thank you for sharing.

Another fascinating and informative lecture/video. Thank you so much Nick for making these available. Such a gift!!!!!!!!!

If I had a teacher like him I would be a geologist today. What a great resource for people to have. I am in Kansas and started looking for the same type of things about my area and what I find is (be nice) not the same caliber. Anyway thanks Nick and you may see me in your class in the winter of 21-22.

Dear Nick, thoroughly enjoy your lectures. I am an Australian but spent a little time in Washington State and have some feel for the area. Had I seen your lectures at the time, I would have paid more attention when driving around. I work in China now and pay a lot of attention to the local geology but have no explanations equivalent to your lectures here. Many thanks.

At 33:50, the hazy sky of the 1882 photo can be explained by the blue (and UV) weighted response of photographic emulsions of the time, they barely picked up reddish light at all (thus red safety lights in darkrooms). It wasn't until the early 20th century that dyes were added to the film to enhance red sensitivity, and Ansel Adams was able to use blue-blocking filters to achieve his dramatic dark skies.

Just ran into this, great presentation. I'm sure? you've heard about Quake Lake, in Montana. The dead trees in LOTG reminded of the trees still standing in Quake Lake.

Just found this,01-02-23 Have seen others of your presentations. I Love them. VERY interesting. I used to live (45 years) blocks away from Lake Michigan, south of Milwaukee. Now I live at the base of the Sacramento Mtns in Alamogordo, NM. Just as fascinating here but warmer.
