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.

Im just an old grandma that has always loved geology. Thank you for making this information available to everyone.

Damn it, came here to fall asleep, but after a few nights I ended up learning all about the geography and geology of the Pacific Northwest.

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.

Prof “What evidence can we find for a landslide? We look for a pile of rocks! This isn’t rocket science” No, it’s geology...rock science

Nick and Randal Carlson have changed my life and helped me through drug addiction learning about this true history.

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!

I don't know exactly why UKposts has been sending me here all day but God damn this guy can hold my attention.

I cannot believe Nick’s undergrads aren’t excited about this guy! He’s a UKposts phenomenon!

I’m not even into geology, but I watched the whole playlist. Stunning lecturer!

Another great video that makes this ole retired Geologist happy. Thanks for posting.

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.

His chalkboards are time machines!

I loved the lecture. I'm sorta binge-watching your classes. You're a great teacher. Thanks

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 .

I would move to Ellensburg just to have the opportunity to attend some of his lectures.

I wish I could find someone who does talks like this on our Tennessee/ Mississippi River/ Smokey mountain geology. I’ve watched a few of these, and I really enjoy them.

Gotta like a guy who uses a conventional chalk board!

Another one? What a week to be alive. Currently ignoring my history homework to watch this.

An hour with Nick Zentner makes most Nova episodes look shallow. Thank you. If only there were somebody doing the same for Michigan geology (where I live).

This is a truly wonderful presentation! Conducted very professionally, unbelievably thorough for the amount of time used and explained in a manner that someone like me can comprehend!

This is really good series. I've driven through the area for years and have always wondered about it's geologic history.

This guy is a great teacher. I've never been interested in geology,but he really makes it interesting. 😻🌋

I lived in Seattle for 11 years then moving to Yakima for 5 years. Your lecture really opened up my understanding about what I was seeing all those years ago. Thanks

Prof. Zentner: Your passion for geology and your skill as a presenter have infected this Canadian computer guy. My life has been considerably enriched. Thank you.

I'm an older guy who never studied or read much about geology. I find these lecture fascinating. I want to keep learning more. Thanks so very much.

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 :)

Nick Zentner is without a doubt a Living National Treasure.

I just found these lectures and am fascinated. What an excellent teacher.

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.

I really enjoy Nick Zentner's talk's.... Very intelligent and personable speaker!! .... Thank-you to everyone who helps put these video's out here!!

These lectures are so interesting. Reminds me of Penn State geology Professor Lattman in the 60's; his lectures were so good that hundreds of students "audited" them every day.

Nick, I really hope you continue to post these lectures on here. I have learned a lot from you, and greatly appreciate your efforts.

Honestly; recently everything has felt so meaningless in life, but these lectures help me keep the absurd nausea at bay. So thank you :)

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.

So glad my son attended CWU. He now is teaching high school history classes and also enjoys your presentations. Your style of presenting information is very enjoyable and entertaining. You are so good I don't even realize that I'm learning! Keep up the great work!

Natural speaker and probably an amazing teacher...I'm a right-ponder, had barely even heard of this river, and was immediately hooked, and stayed...which makes him just a tiny bit special...

This is just great. Nick is teaching me to like geology. Oh nooooo! Thank you Central Washington U!

So wonderful to learn from a lecturer who's so animated and passionate about his topic and so knowledgeable! Fascinating information! Thank you for sharing this on UKposts!

Nick, thank you sir, these are great videos. I now find myself slowing down a little more as I drive up 410 and other areas to notice exactly what you are speaking about.

Brilliant. Especially as I've been there from the UK. I remember dry falls lake, there is a distinctive knotch in the cliff where the flood happened. I also went to East Washington desert, saw the petrified trees and the Colombia River which is huge. Love geography.

Oh wow. These are awesome. Please don't stop making these, Nick! I can't stop watching your lectures. (And I've never known that I'm into geology.)

This is one of several videos by Mr. Zentner that I've watched. I am not from the Pacific North West but these are fascinating lectures and extremely well presented. Thank sir.

I opened this video and a minute in I opened Google Earth once Prof Nick mentioned the location of the bridge and as I zoomed out to see the general lay of the land I saw the cliffs of Greenleaf Peak and Aldrich Butte and I literally went "Holy sh*t that is a frickin huge landslide." 😮

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.

Nick is a great story teller... and teacher... all based on the fascinating science of Geology... I thoroughly enjoy his videos... thanks Nick!!!

I love the way he draws your attention, then rewards it : never boring , never patronizing.🦉☺️. The more you see, the more you want to learn! The best kind of teaching ! Look how many older folk are there : it's never too late to be inspired ! I'm best part of 75 , and these lectures are a revelation, a lovely development at a ripe age ! ☺️. I had a chuckle when a cliff had unusual strata / dark stripes : I muttered," They're Basalt Feeder Dykes". Then, " Oh, hark at me !!"😊 Greatly looking forward to learning much more. I love the field trips : it feels as if you're really there : you get the parelax, as the little video camera moves along, with the amiable Professor's narration.🦉⛏️🌿 Many, many thanks from England.☺️🌿⛏️🦉☺️ 🇬🇧💕🇺🇲🦉⛏️🌿😊🇬🇧

Hi Nick Beeing from the "old"" land I am impressied by your commitment on bringing these stores to all of Us. Great work and Realy interesting for a Northen European guy to see such detailed "lokal" knwalge of the US of A to us, thank you Very much.

I could listen to Nick Zentner all day long.

Driven those roads without giving the geology much thought. Now in my 60’s I’m fascinated by all this. Can’t wait for my next road trip to look at things with a different perspective.

Two lectures in one night! woohoo!

We are so lucky to be educated by such a wonderful enthusiastic professor. I feel spoiled. Thank you for taking the time to share with those of us way beyond our college years.

Omg I’ve driven through this area so many times and never realized this was a landslide area. So cool. As a newbie rockhound I’ve been trying to learn about the geology of the area to know where to look. I came across your ancient rivers lecture and got hooked. I love learning from people that are excited and passionate about the subject they are teaching. I live near Mt Hood but if I lived in WA I would totally go to all of your in person lectures.

Came for Stevie Nicks at a live music fest, stayed for the actual rocks that rolled.

Im 61, and I want to thank you for this series. Im on the East Coast and have wondered about the geological history of many places. From past events like Cumbre Vieja like events, like off the coast of Morocco, to the effects of the Puerto Rico trench, from earthquakes to landslides. Im getting a lot of education from you and trying to envision both past and future events. Thank you for this entire experience.

As always, thank you for all that you do. Looking forward to the next series

You might want to take a look at the timelines on the 1959 Hebgen quake un Montana. 7.5, and a mountainside slip that blocked the mouth of the Madison Canyon. They decided to bring in the army corps of engineers to cut a channel through the slide, and by the time they got there, the river had already started to cut through the top of the slide. There's lots of documentation, photo and text, and might have some info that corresponds here.

I'm so grateful to learn from these presentations. I live right near the bridge and have been fascinated since 1988 with its geological history. THANK YOU GUYS!

Thanks Nick, crew and CWU for these lectures. Very interesting to me as in early August 1959 I camped in the campground that was wiped out by the Quake Lake Slide that was caused by the Hebgen Lake earthquake. In a few months I will be going through Ellensburg, might stop in for a lecture if there is one at that time. Your lectures and Iron Horse Brewery are high on my list to visit there. Be well friend.

I lived in Washington in the late sixties and have watched all of your series it is so nice to see the areas that I used to travel through and now I understand the geology much better thank you Nick keep it up

Nick, after coming up here since I was a kid to see my uncle in Seattle, I was 6 at the World Fair in 1962, it's been my pleasure now to live up here since '06. You have a wonderful set of teachings here on UKposts that are such a great source of college level knowledge! Thanks so much for making it all available!

Between 2011 and 2017 I transported a number of travel trailers through Oregon and Washington state. I was astonished when I realized I was seeing all that old lava layers and miles and miles of lava flow sheets. Well I in the last month after I found your lectures on UKposts I am beginning to understand what I saw with my own eyes. Thanks for your lectures and the hard work, I would love to attend you classes some day. It is a long way from Indiana.

Great video. I'm not even from WA., but can't stop watching these. If today's teachers had just half of your ability to teach a subject, we'd be a lot better off. Thanks for putting these out there!

Nick's enthusiasm for geology is infectious..

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.

Excellent lecture, I'm from another world on the east coast. Been watching your lectures on you tube for a few years. I always have google maps open in another tab since your speaking to locals that know your area. We have nothing that compares to the geology of the Pacific North West. I've never been to your area of the country other than you tube videos & content of your geology lectures. If I wasn't so old I'd want to be a young man in this region, maybe sit in on one of these lectures. I'd be a rock hound for sure. what we missed by not having you tube in the early years of ones life. Stay safe Nick.

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

Great lecture what Nick does is greatly appreciated!

OK i am not a student anymore - at least not formally, I am 66. I do love to learn things, however, and this is the third lecture by Nick Zentner that I have "attended". He makes learning fun. His teaching is interesting, you follow the discovery, the additional digging for information needed to explain the discovery, the inclusion of scientists of various disciplines and the very open conclusion showing the current understanding of what happened. I have never thought of geology as being a fun and exciting subject - but I think I see why it is to a geologist, and why I am starting to feel that way too. This is information that seeks to understand the world as it is - and to understand what made it like that. Sometimes that begs the scientist to consider the future - something most don't like to do as its very hard to pin the future down. But there is definitely information here that allows you to consider the fact that the planet is still moving, still building, still taking things apart, still changing, and we are just along for the ride. Now that, professor, is fascinating stuff! Thanks for letting the rest of us attend class with you today!

Absolutely fabulous Sir. Thank you. You love this subject. Its contagious! You make it dimensional!

Thoroughly enjoying all these outreach lectures. You are an amazing communicator and the lecture was pitched perfectly to the audience. I came to you via Shawn Willsey and now spend a huge amount of my free time learning about the PNW … an area I only knew of from tv and books. I live in the uk and the geology of the PNW is amazingly complicated and diverse, absolutely fascinating. Thank you Nick…. Next it’s the A-Z of the Ice Age Floods…

Some very beautiful country out there that I didn't even know existed in this country . Loved the lecture , Pat was very entertaining . He would keep you awake and focused..

Thank you. You have made geology understanble to me. Whish you had been around 40 years before you were. May have wound up being geologists in stead if just a rock hound. God bless you.

I always learn something from these video lectures! The power of nature is amazing!

The tragedy in this wonderful thorough piece is that Nick Zentner isn’t a more knowledgeable enthusiast entertaining gifted presenter.

Enjoyed my geology afternoon with Nick. Thanks

I have thoroughly enjoyed watching Nick's series. Excellent, informative and never boring.

I ordered Roadside Geology of Washington and Oregon yesterday from Amazon, both arrived today. I am SO excited. I haven't seen one of these since around 2000. Thanks for the recommendation. They look excellent.

I'm an old grandpa who once took my kids on a flight to Mexico; the landscape of SE California is great for the geologic view just north of the Gulf of California/Sea of Cortes. From that altitude a basalt flow can show the same curves as a drip of candle wax, and the darkfissures and flows contrast well with the blond dry grass.

Makes so much sense! Thanks for the great information as always. Enjoy your work. I can’t wait to visit Washington.

I love the chalk boards! I'm from the age of chalk boards. So it doesn't make me feel too terribly ancient.

Really entertaining ,but what's more important, really educational, really, really, REALLY GREAT CONTENT..

I've flown my airplane up the gorge so many times. This all makes sense.

If only all of my college professors were like you. I really enjoyed this lecture, and enjoyed learning the history of where my family originated. Thank you for the way you teach!

I lived in and around Roseburg Oregon for 25 years. At the south edge of the I-5, the Pacific, Klamath and Cascade plates meet. About 15 miles east of Roseburg the only place in the world two rivers smash head on. Called Colliding Rivers. It causes a bubble with air where it appears a person has drowned. A gag on tourists. 70 miles east of Roseburg is Crater Lake. 2nd deepest in the world. I retired to Panama in 2013. Lived in Nicaragua , Ecuador as well and for the last 4 years Costa Rica. Living retirement as it should be. Enjoying travel, archeology, geology, volcanology, history, mountain biking in the Andes at altitudes as high as 21,000 feet. I will be 75 next month, take no medications, BP 104/55, resting pulse 56. I bench press 242 pounds in spite of having had 11 bone surgeries, 3 bone grafts and titanium enhancements on my left arm. And this year making up for my usual 3 months of International travels per years flubbed up from the Pandemic. I will likely be traveling 9 months this year, already at nearly 7. May be going to Munich Germany for Oktoberfest later this month. Earthquakes? I went through a 7.4 Magnitude one in Managua Nicaragua October 13, 2014. It was actually fun. The cement walls looked like flowing liquid cement. Especially the west wall. Only thing of concern was the air conditioner unit on the roof. No way was I going to go outside in the dark where there were electric wires and trees to worry about. A 6.3 quake had destroyed two thirds of Managua in 1973, forcing Howard Hughes out of the International Hotel there. About 3 kilometers north of where I was staying on the InterContinental Highway Route 1.

Goldfinger was my teacher at Oregon State! Never will forget his name, knows his stuff too.

I absolutely love these lectures, although , almost literally or figuratively I live in Nick’s or CWU’s back yard . Native of western Wa transplanted in 1990’s to Yakima’s Lower Valley , now nearing my aperture of 60 yr I would never in a billion yrs ( geology speaking ) have guessed that I would be so struck by rocks and Nick’s video lecture series played huge part . I like to describe Nick as the Bob Ross of Geology 101 Great Work to all of CWU and contributors to the exploration and recognition world wide ( web anyway) of new information right under our feet or mine at least .. and this year I will get there for some long overdue seat time!

I drove right passed this just a year ago coming home from the Grand Canyon with my daughter and 4 grandchildren

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

Nick. Your A Geological Ninja. Thank you for helping me learn about the great Pacific Northwest. Always have been interested in the geology of our area.

the first time I heard about the Ice Age Floods in the Pacific Northwest was reading about the geologic detective work that went into analysis of the English Channel and it was formed when Doggerland was submerged by the big tsunami caused by the subsurface Norweigan slide - the geologists were familiar with the geologic features the Ice Age Floods caused by breaching the glacier/ice dam of Lake Missoula and how they found similar features in the bottom of the Channel - as well as matching up the sediments along the English and French coastlines - I guess once you begin you just can't stop learning about geology and history!

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.

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.

I really appreciate the great, informative content you provide. Thank you.

Amazing lectures. it is like reading geology detective book. Also Nick's sense of humor makes these stories addictive!

Columbia River Gorge where the wind blows only twice a year. 6 months from the East and 6 months from the West. Railroaded on the Oregon side think it was 95 or do floods and landslides railroad tracks both sides of river hanging in mid air from wash outs. Landslide washed out a couple of miles of track. Was a foreman and had to shut down the line. A lot of what we called close calls and a bit dangerous at times railroading. Ice storms in the Gorge were magical.

Bravo! Science for the People, not just Academic Elites.

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

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.

I know you primarily do Washington, but would you ever be interested in doing a lecture or even a 15 minute video about Oregon's John Day and Painted Hills area? Your explanations of geology are both fascinating and very informing.
