Lake Chelan Geology

CWU's Nick Zentner presents 'Lake Chelan Geology' - the 18th talk in his ongoing Downtown Geology Lecture Series. Recorded at Hal Holmes Center on February 8, 2017 in Ellensburg, Washington, USA. www.nickzentner.com

I really like the "localisation" of these lectures. I'm a Brit, I've never visited the USA, but I kind of feel like I know this area now, if you see what I mean. I'm really enjoying watching all these.

Great. Thanks much. Come visit!

I live in Texas and have made only one short trip up to the Seattle area (although, I was able to drive around that week and visited from Olympia to Enumclaw. I HATE geology (hate might be too strong - but it does bore me). I even have a friend who is a geologist and who has tried (in vain) on several occasions to get me interested. Nick is such a good teacher that I could literally watch these lectures back to back (and I have, several times). I've even watched some episodes over and over again... they're that good. I never imagined that (at age 56) someone would be able to entice me into learning about geology for an area of the country that I don't even live in. Of all the things I've ever seen on KZbin, these are the best things I've stumbled onto. CWU is very fortunate to have such an amazing educator as Nick Zentner.

[@rachelfeuerbach7187]

He's way better than virtually all of my geology professors were!

[@cammontreuil7509]

Seattle is the worst place in the whole state to go to.

[@loge10]

​@@cammontreuil7509It wasn't always that way. I spent my twenties in Seattle - from 1976 to 1985 - and it was a great place to be. Back then it had even been voted the most livable city in the US. It deeply pains me for what it has become.

[@befuddled2010]

Having watched many of Nick Zentner's lectures, I appreciate how he admits over and over again how the information he's discussing was new to him in the recent past. It just illustrates how engaged he is in his field and how hungry he is to understand as much as he can. He never stops learning and this is what makes him such an immense asset to his students (and to us). If only more college lecturers conducted themselves and performed likewise. I honestly hope there are legions of instructors at every level of education like Nick that we never hear about because they don't have KZbin channels.

[@harrietharlow9929]

I like that, too. So many instructors don't want to admit that something is new to them. I love when people want to learn new things, so I really appreciate Nick and the information he gives us. He is a PNW treasure!

[@mikel9567]

I'm not even a geologist but I find his lectures fascinating. Living in WA my whole life it's interesting to learn how this area was formed.

[@farmergiles1065]

Really impressive to hear how deep Lake Chelan is. Its bottom is 104 feet below the floor of Death Valley. And yet it was carved in the midst of mountains! The power of ice is mind boggling.

[@tomwestbrook]

I think you can gauge how much fun he’s having by how much chalk he’s covered with at the end.

[@dennislloyd44]

Nick; 70 years old and still learning, you are a master teacher. I love your lectures ! 73 - KV4WM - A US Navy Nuclear Submarine Veteran and Licensed Ham Radio Operator.

[@johnflavin4193]

The ability to energize a willing mind is rare. Getting people excited about geology is often like leading a horse to water, yet field work is what made me become a geologist. Well done!

[@helenaj9436]

Mixing it within history got me interested. General geology can bore me. Lol. Looking at them together has me addicted to these video's.

[@markfox1545]

'Getting people excited about geology is often like leading a horse to water'? What a fucking stupid and bizarre thing to say.

[@russellmooneyham3334]

I'm SO EXCITED!!! Just found this video. Thought I had seen all of them! Great way to start 2021!! Thank you professor Nick!!!!

[@saltyc]

Having had a fascination with geology since I was a child, I just love these lectures! I grew up in Utah, which has its own fair share of interesting geology. But I've learned so much about my new home in Washington/Oregon thanks to these!

[@thetawaves48]

If I had Nick in college, I would have changed my major.

[@helenaj9436]

Same

[@aspencrest]

I was wondering the same thing. Scary to think that a professor, simply by his enthusiasm and charisma, could send you down some potentially wrong path. (or right path)

[@drhyshek]

We would ALL be geologists .

[@longcastle4863]

Learn more about geology from Nick than any documentary on the subject. He is a gifted teacher.

[@paulebberson4884]

Another fantastic lecture from Nick where he roams far and wide and from detail to big picture in the world of geology & geophysics with a twist of Tourism thrown in.. Lots of new stuff in this one presented in an unbiassed way. I liove how he leads up to the big questions and then stops short especially about what is going on between the Crust and Mantle, plumes etc. Keep up the great work Nick and I hope you get properly recognised in Washington and the US for being a great ambassador for both.

[@loge10]

I think I just found my new KZbin addiction... I lived in Seattle during my twenties, long before the tech companies ruling the area. I have traveled many of the places that Nick presents. It is so wonderful to get this much understanding of geology the areas I used to explore and love (and still love). Nick is amazing.

[@teacherdustinpnw]

I watch his videos more than anything else, but I also grew up on lake Chelan and love the geology. It overwhelms the perspective!!!

[@joelspaulding5964]

What an incredibly engaging lecture. My 11 year old has geology interests. This is perfect for her to see a big picture of the subject. Personally, cannot stop watching. Great stuff.

[@johnfalconer3672]

Just returned from four days in Chelan and was poking around the internet for information on the geology there. Great video! Thank you, Professor Zentner!

[@groglong]

Thank you so much. Born and raised in the Chelan Valley and never learned so much about my home in such a short time. An hour well spent.

[@Ellensburg44]

Terrific to hear, Rick. Thanks.

[@markp.9707]

Agree! Born and raised in Wenatchee and have driven by Ribbon Cliff hundreds of times on our way to Chelan. Very informative and excellent delivery of vast amount of information.

[@flyingfishwausa6391]

Nick, you're a 'Rock Star'!! I have been captivated by the geology of North Central Washington for many years and you have made it so much more clear. I took a geology class many years ago from Warren Scott at Wenatchee Valley College. I loved his enthusiasm for his field, just like yours. I used to have a courier route from Wenatchee up to Okanogan, Omak and back down the Methow Valley. I always had so many questions about what I was seeing. You answered many today. Thank You!!!!

[@Ellensburg44]

Thanks. I need to learn more about areas north of Chelan....I'm sure you know more than I!

[@danothemano4129]

Same! I’m in northern Kentucky! We have our lovely rounded hills from glacial ice sheet here also.

[@lucygardner5666]

Me too 😊

[@michaelhusar3668]

I found a few channels that cover Ohio geology. I found them interesting. I live in Indiana, home of the least interesting geology in the country. That's why I enjoy Nick's channels. Washington probably has the most interesting geology in the lower 48.

[@who9387]

I am loving all these lectures, Nick. Soooooo interesting, I live in UK and have never even been to the US.

[@HJWhitehall]

If you ever come to Washington State, make sure you give yourself plenty of time to enjoy the geology. There is so much to see. Grab a copy of Roadside Geology of Washington. It's a tool to see all the good spots and points to interest. Or, I could show you myself. I know Washington State very well and all the geology of Eastern WA. I am making my way to London in March. I can't wait to see England as this is where my family started before coming to Washington State. Cheers.

[@rationalcapitalist]

If you ever come to the US, you should visit Washington. It's one of the most beautiful states.

[@jeremyowen1]

I love this mans energy. If I had professors like this I probably would of been more interested.

[@kenbrown9164]

This guy reminds me of Dr. Dave Rahm a professor that taught at Washington State University in the 1960's. His lectures were very popular and similar to Nick Zentner's. It was very difficult to get into one of his classes. He lectured about the geology of Washington state also. Many students that had no previous interest in geology took his courses just because he was a passionate and entertaining teacher. He was also an aerobatic pilot, and sadly he was killed doing an aerobatic flight performance for the King of Jordan in that country.

[@TrainLordJC]

Another one of your excellent lectures put to video for people all over the world to appreciate. I live in Adelaide, South Australia but travelled through Oregon and Washington on my way to Alaska driving my VW campervan in 1988-89, but unfortunately geology was dormant at the time. However, as a result of my many travels I have come to really appreciate the magnificent geology of the planet and I must say it would be an absolute privilege to have you as a geology teacher. Your teaching is remarkable in detail of that wonderful area of the US. You and your students are very lucky to be living there. I have watched all your videos. Please keep them coming. Thank you for sharing. Cheers from Australia.

[@Ellensburg44]

Hello from the US! Really appreciate you taking the time to write. Nice to hear these lectures are being enjoyed so far away!

[@wesmahan4757]

And Australia has some of the oldest exposed geology on the planet. Really ancient rocks (and stromatolite fossils) that exist in very few other places on earth.

Thank you so much Dr. Zentner! You're energizing new generations of geologists with your accessible and fascinating lectures!

[@brianvittachi6869]

Thanks to you, Professor, I now look at mountains and the surrounding terrain with new eyes. They tell a story that I am only just beginning to understand. I have more questions than answers, off course, but my journeys are so much more interesting now.

[@craighoover1495]

Living at Mtn. Home AFB Idaho Dad took the family to Lake Chelan and a boat ride up to a faith based village so it was interesting to hear you talk about the geology of the area. Also living a year in Yakima and working for the State Dept of Ag I spent a lot a lot a lot of time on the road in the areas orchards, vineyards, pea and lentil, and wheat growing areas. So drove thru a lot of the cuts shown.

[@IanTruthSeeker]

I wish there was someone like Nick teaching about the great lakes and Niagara escarpment

[@jamessuhr9667]

Greetings, from the foot of the Taranaki Volcano. Well said sir.

[@HJWhitehall]

My father grew up 4 miles north of Waterville, WA and speaks often of the earthquakes in the area Chelan area. My family goes back several generations of farming and living near Chelan, Waterville, Wenatchee, and Entiat. I am very familiar with Pine Canyon on Highway 2 from Orondo, WA, just across the Columbia River from Orondo, as Nick explained. I have always heard about small quakes, big quakes, and the quake that caused my uncle to fly out of the outhouse with his pants down on my grandfather's farm. It's a great family laugh. I am so enlightened to put the December 14th, 1872 earthquake to rest. My family has debated the location of this quake for generations and thanks to geologists and the technology of LIDAR, we have found the source. Thank you, Nick, for posting your video lectures. I can't wait to share this with my father. P.S. My husband, Jason Thompson, was a student of yours at CWU. He says, hello!

[@garyechols9458]

Sir, you have a gift, thank you for sharing it with us.

It was a basalt fissure crack shooting out very interesting formations

[@lauriebolles3149]

This Conneticut Yankee lived on two pieces of land that both had Glacial Erradics. The first one in Weston had two huge boulders pushed up against each other. My brother, sister and I had great fun climbing all over them. Then we moved to a property in downtown Westport and had a large boulder that had a bronze plaque on it of two native women holding grain sheathes. The Erradic was called "The Threshing Rock", again a great thing to play on. I wish I had known then that these Erradics were transported from way up north by the Glaciers.

Another great one. Even though I live in Minnesota my father and his brother had an orchard above Manson which was one of the highest elevations of any orchard there. Picked apples there quite a few times. It was great to look out out across the lake and mountains. My uncle had a good understanding of geomorphology and explained quite a bit about the area--especially the "glaciers" from both directions. This was back in the 1970s. He was also the one that first introduced me to the Missoula floods, the dry falls and the basalt erratics out in that area. I will contact you via CWSU website

[@waynep343]

be sure to review the Nova on mount st helens awakes. and look carefully at the percentage of water area in the magma . as there are some spires pushed up out the south west face called the black buttes that might be similar to the pushed up towers in st helens. but i was also noticing that sherman creator might be a lateral eruption so very little water will collect and percolate down to become steam causing additional volcanic activity. the long phase and short phase harmonics also need to be included.. i would think that the odd feature viewed in google maps satellite view about 200 miles west of Sitka Alaska might be an interesting lecture or field of study also. somebody did take some core samples a few years ago on an east west path across it but i don't know who did it or if they have examined them yet for fractured quartz. its a depression with a raised center like an asteroid impact hit the surface of the ocean sending a shock wave column of ocean straight at the bottom where it would spread out like a microburst digging out the depression and leaving the high spot in the middle. the feature is about 18 miles across so its easy to see. imagine the speed of the ejected seawater as the astroid hit.. followed by surface waves. then the tsunamis running along the ocean bottom from the massive column of water hammered toward the bottom of the ocean and spread out. i would love to contact researchers extracting siberian mammoths to see if any ice samples were viewed to check for signs of ocean life.. the salt would have fallen out when it froze.
