If someone told me in college that in the future I'd be watching 1 hour geology lectures for fun, I wouldve laughed in their face. But here I am!

Everyone should have an enthusiastic teacher like you, Sir. You definitely further stimulate my interest in geology. Thank you.

I retire from the Army this year and was unsure of what I wanted to do. I knew I wanted to go back to school but didn't know what I wanted to study... until now. Because of you Sir, I want to study Geology. You are excellent at presenting the information that keeps people interested. Thank you!

I can't get over thinking Nick as Al Bundy with a geology degree. Peg! There was a mudflow right here 10 million years ago, about the last time you cooked a good meal!

Great documentary, excellent teacher. He used many techniques, video, story, humour, other speakers and honouring others in the field. Hard not to like him.

I never knew that geology could be so intriguing.. Your enthusiasm is really contagious and I've learned a lot from watching these lectures!

I want to thank you so much for having all of your lectures here on You Tube. I have been very interested in geology since the age of twelve (Jules Verne got me hooked with Journey to the Centre of the Earth and his vivid description of the eruption of the Mysterious Island's volcano). You have provided me a way to learn more of the fascinating rocks of our planet.

I'm from the UK and just love these lectures, with every one I learn something new. Wish I'd had a teacher like you when I was at school as I now find myself fascinated by Geology. Please keep the videos coming.

That gentleman can really give a lecture. Never seen him interviewed or talked about....very knowledgeable. His lectures are always very interesting. Wished I had teachers like him back in high school.

I will probably end up watching all of Nick's stuff on UKposts, many times. Fantastic stuff ! I should have studied geology.

My wife and I flew over Mt St. Helens in September 1980, 4 months after the eruption. Every stick of lumber was laid over like a million toothpicks, away from the blast wave, for miles around, and Spirit Lake was a log filled muddy patch.

I got here after watching a short video on Arizona volcanoes, I will be bookmarking this, very exciting and easy to understand.

I've learned so much from these! I don't even know where I found them first but I listen to them right before bed and it's awesome. Thanks for making these!

It is just absolutely incredible to have anything flowing 600 ft deep flowing from a volcanic mudflow! Albeit, it isn't not too terribly difficult to understand why it was that deep, but that doesn't make it any less incredible! Also, thanks for all the lectures you do, I will go back and re-watch these because there's so much to learn and I guess you know the content is good when you want to go back and watch it multiple times- whether it be two consecutive days or every few months, etc. I definitely hope you guys can you doing these and read new episodes when new research comes out like you have done and so on. This is one of my favorite series on UKposts 😊

I lived in Sumner, WA for four years in the mid-1980's. Sumner is built on a mud flow. I managed an apartment complex while there. I could see Mt Rainier out my front window. When a bus went past, my whole building shook noticeably because we were on wet mud. Crazy place to build.

Perfect tone,diction and sound level. I could listen to any subject he is talking about.

I love this guy, wish all my teachers over the years were half as enthusiastic!

I grew up on Bainbridge island. I grew up as a commercial salmon fisherman. My dad taught me how to run a boat and make money catching fish. I am now working building solar panels, currently in north Carolina. These videos make me feel at home. As a Washington fisherman, I learned to respect the land. Being away from home.... I can say I like experiencing new beauty, but there is nothing quite like Washington beauty. And because of these videos I can actually understand why.

I really enjoy watching your presentations. I hope the people of the Pacific Northwest know how lucky they are to have a man like you (and all the others Rocky to you) watching over their geologic happenings, for lack of a better word. I see and feel your passion and at 61 it's renewed my passion to learn how our environment past present and future was, is and will be (kinda). Keep up the good work you're a fantastic teacher

Thank you Nick Zentner, you are really helping me teach my third graders about our Amazing Region!!!! The LOVED the video of Dry Falls!!!!! Especially your little RV!!!!

Prof. Zentner is the kind of professor that might very well get me majoring something I never intended to major in. Very good stuff.

We need a teacher like you in every college and university. Keep it up Sir.

Please explain to me how I am able view these world class lectures, for free. These are the greatest. Love them!

Great lecture Nick, you really are a brilliant communicator!

I have always had an interest in Geology and thought about being a Geologist at one time. I was always looking for rocks for my collection, so I always walked around looking down. Then I found out that Geologist don't hunt for rocks per say, so I pursued a different career path, but Geology still fascinates me. Very interesting history of volcanic activity in the Northwest.

Love this video. I rewatch this every once in awhile as I learn more from Professor Nick through his abundant videos. Thank you, Nick!

4 years ago. love your lectures. wish i was there.

We need more Nick TV... I'd love to see new content, even if its about the same subjects or overlapping. Great work!

The time frame of the mountains is very interesting. I thought I was feeling old. I was in the geology club 40 years ago in Illinois. What a great time watching this class! Thank you.

Thank you for an excellent presentation of the mud flows into the area from Mt. Rainier. I remember 25 yrs ago reading about the ancient logs found in the Orting and Puyallup valleys. I did not realize the immensity of these flows. Again, thanks for another excellent presentation.

All I have been doing lately is learning about Mt. Rainier’s activity, history, and geology. I’m regretting not getting my bachelors in the sciences again. Thanks for making science accessible and engaging!

these lectures make me really want to study Geology now.

Yet another fabulous lecture!!! In my wildest imagination, I can't fathom that ANYONE would get - as you put it - "impatient" with the pace of your presentations. Not possible!! I used to live in Wenatchee, so each one of your videos is like 'going home' and appreciated more than I can say. Can't wait to watch them all. Thank You!!!! Love the PNW!!!!!

Love this guy and his lectures - bringing enthusiasm and passion back into geology and science. I don't even live in Washington, just tuning in for my own curiosity and quest for knowledge.

I feel like the st Helens eruption was a blip on the radar. in hindsight, it is more of a treat than anything that it happened in our lifetime. We may never see another eruption like that again in the cascades for a while. Also not only are they so beautiful, provide habitats and places for snowboarding, it gives you granite when its all said and done

Im from Enumclaw also. You have a gift at speaking and teaching about our beautiful state. Thanks for all the knowledge !

I think I'm on my 6th Nick at night binge watch. Neat AND on the rocks :-) Thanks! -Jake

You rock Nick, no pun intended! I have watched many of your lectures and like most viewers, I find your teaching style and information to be so freaking interesting and entertaining . I hope CSU values you as much as your audience does. I admire and respect your contribution to both teaching and geology! Rock on my friend! 😎

I love this guy. I wish I'd gone to his school! I love animated educators whose passion is contagious.

I am captivated by natural beauty of Washington. I'm from NC and I've visited twice! Wish I could live near all the amazing geology! Thanks for the lectures!

washington is an awesome state for a geologist!!!

Great stuff Nick! I'm a native Washingtonian, 73, I'm hooked!

All teachers should have your passion and enthusiasm.

Love your channel and your explanations about our coastal geology. Please keep making these videos. Thank you. God blessed

What an excellent teacher in the way he gives the presentation . Love the way he delivers the information.

Gosh I'm loving these lectures! Nick, you're a fantastic lecturer! Makes me want to learn more! Also wish we had more interesting geology in Australia... I know we've got very old rocks and stromatolites but nothing as exciting as active volcanoes, glacial lake dam breaks, fault lines and such. Please keep sharing these with us Nick!

Beautiful pics of Rainier National Park. Wish the weather had been better the week I was out there. And Nick is a great teacher. What an education in geology and volcanology. This is the reason video and the internet were invented.

What a sight it will be when another giant eruption comea to WA. Each time I think I feel the ground shake in Seattle I think about first the fault offshore, the to Ranier. The area thinks it is prepared, but like St Helens in the early 80s,it will give the State and the country a black eye. Could you imagine a lateral blast toward Tacoma?

The White River canyon that forms the Pierce/King county line today that starts at Buckley and ends at the Game farm park in Auburn has several visible Osceola deposits. I grew up in Bonney Lake right by the canyon.

"You can never truly appreciate a volcano until you have climbed it" ~ Steve Spear PhD

All of your lectures are mesmerizing. This is one of my favorites. It would be great to catch one of your presentations someday when I can schedule vacation time. You may well be the John Madden of Geologic Science.

I am fascinated by these lectures. Pat Abbott was my professor of Geology at SDSU. Similar approach. Dynamic and keeping it real. Thank you.

I've been reading about geology and the pacific northwest for about 20 years, and it makes so much more sense now, finally. Of course, now that it makes so much more sense, it also makes me realize just how dangerous it all is. And that it WILL happen ...

We need this Man to teach Calculus!

Nick my husband's name is Jerry. I lived in Enumclaw in the Osceola area from 1955 until 1967 when he was transferred to Kent when Boeing built a plant in the valley. Until you talked about our mountain,s last blow. I didn't know about this until your lecture.

I'm ancient by most people counting 67 years and I'm still watching his videos because he's an excellent speaker and educationally enriching

Outstanding Lecture by most outstanding Lecturer. Value ++. No filers, straight to the information with many easily followed connections. Yes with some comedic bonding, loved it.

He’s a great teacher ❗️❗️ I have enjoyed every presentation of his that I have seen. Thank You ‼️‼️‼️‼️

It's always enjoyable to come back to the video that got me hooked on Nick Zentner and the geology of the Pacific Northwest.

One day we will loose this great man. I hope not in the near future. He loved his career and his students and the world loves his lectures. Thank you for still showing them on the internet. I can never get enough of him talking about our earth. Yes I was a rock picker. Only if I knew he was teaching this in my younger days I would have moved to attend his classes. I did end up working in the worlds largest lead smelter. But my heart was with my hands in the dirt picking but had no clue what all I held in my hands. Yap I found diamonds.

I have watched your videos for about a year. I'm a geology buff. Somehow I've never seen this particular video about the the mud flows coming off of Ranier. Really well explained and visualized.

Love these videos; very informative. 76 years old? I would have thought no more that 56 years old? Great genetics?! Please continue to make these videos❤️

Another one of your excellent videos describing the amazing geology landscape in your area and even though I live in Australia I enjoy so much to watch your very informative lectures. I would be amazed if anybody fell asleep in your lecture hall during your discussions. You are an excellent teacher and lecturer. Thank you again.

I never realized how dangerous Mount Rainer really is. Great video. Learned alot. Im a lil nervous after that giant mud flow that happened August 5th.

Such an enjoyable relief to get a solid and steady presentation like this, instead of the usual overly-dramatic disaster tripe that the networks push out as "educational material". You should think about doing some documentaries.

Sir, you are a teacher's teacher. How I wished you had been my Geology teacher. Your style, passion, enthusiasm and knowledge is impressive ......i will watch this lecture several more times.....I look forward to your other videos.

I second other opinions here. The man knows what he’s talking about and can make it interesting and entertaining. Wish I had had instructors like him in school. Can you imagine how much more interesting high school and college would have been and how much more we might have learned if more teachers were like him???

Someone else, that was killed when Mount St. Helen erupted, was Harry Truman. He lived on the side of the Mtn. and was interviewed before the eruption and was told to evacuate, he refused to leave and he didn't make it. I've often wondered if he was related to Pres. Harry Truman. But I felt sad when I heard he didn't make it. I remember when it erupted, thinking about him still being there. He was an old man, I'm sure he felt he ha lived long enough, but still.

56:54 wow, that was a lot of mud and pyroclastic material dumped into Puget sound, and Tacoma sits right on it, a potential target for another Oseola slide

I find this and all of your lectures I’ve viewed so far incredibly fascinating! I swear I got into the wrong field! Thank you for sharing your knowledge and your magnetic personality with us.

Mount st Helens blew on my nephews 1st birthday just 9 months after moving out of Seattle to Utah

I like this guy. Informative and entertaining.

Great video. Wish I had an instructor like you in school. I miss the Northwest.

Great videos Nick, keep up the awesome work! By the way: I am a Floridian and can confidently say that Osceola is said with a leading "ah" sound, the sound that the Seminole tribe uses. It is technically pronounced Asi-yahola in Creek, but everyone seems to say Ah-sceola when referring in English to the historic Seminole chief whom the lahar is named after. en.wikipedia.org/wiki/Osceola

I'm in western Wisconsin but have been to Seattle a few times and I never get over Mt Ranier's incredible beauty. This coming from someone in awe of the Driftless region that surrounds me. See more on UKposts @ Mysteries of the Driftless.

Just fascinating!! I never knew volcanoes could make mudflows like that!

Nick your presentations are WORLD CLASS. The way you create interest in every sentence is priceless. Great job. I look forward to recording you in a future presentation. I will be in touch. Thank You!

Really interesting! A great job. Thank you for making it YT available.

well a. he is a very good teacher .. when I was doing computational math/computing .. the lecturer actually started as a high school math teacher .. but he ended up having an equation in the subject named after him .. and yes Dr Noye was brilliant

This professor is amazing i think i could actually stay awake during his lectures which is amazing for me. He makes me want to go to college

I'm 100% sure that teaching a class as though you're refuting some folk magic is part and parcel of teaching classes at a university in the middle of Washington state on the road to Spokane. 10/10.

You, my good sir, likely deserve a raise.

Nick thanx again from Idaho...ive been teaching myself geology of my area...and your Lectures have been an intregal part of understanding Idaho by its relation to Wa. I was pleasantly suprised to see and Now "this week" able to watch all your recent uploads...Much Appreciation! For doing such a great job in Assembling and communicating the Info!

Absolutely fascinating! Thank you so much

Thanks for another great lecture Nick. I watched the Tsunami vid a few weeks ago and thoroughly enjoyed it also. CWU students are lucky to have such a great teacher. Keep up the fine work.

Just moved to Bonney Lake Washington. Great view of the mudflow.

I really enjoy your lectures. Thank you. I remember Mt St. Helens when I was 13. CDA, Idaho got around 3”-6” (If I remember correctly), Ritzville got around 2’. Messed with vehicles and was difficult to breathe without a mask. Masks became quickly clogged with the tiny glass particles. If you didn’t carry a spare you had to pull your T-shirt up over your face. Was still pretty cool going through the whole ordeal.

When I was going through college, I was taught that for Mt. Rainier you didn't necessarily need to have an eruption in order to generate a lahar, you could get a lahar if you had magma move close enough to the surface that the glaciers melt and the meltwater mix with old deposits.

Awesome lecture and teacher! I'm very interested in geology and your videos gives easy to understand knowledge on this field. Many thanks from Brazil! 😃

Great presentation Nick. Well done.

When I was at school I did only one semester of geology but the lecturer was boring so didn't continue, I wish I had a lecturer like this guy.

If I had you as a Professor in college I would have turned out to be a Geologist. I live in the Tri-Cities, my Grandfather taught me about the ice age floods when I was young and I have always had a thirst for geology. I stumbled upon your UKposts lectures and have watched every single one I could find. I turned my Dad onto your videos as well and about half the time I see him on his laptop he is watching your videos. Your work is much appreciated Sir! Very enriching information and a very captivating delivery. Thank you Mr. Zentner.

This was an amazing lecture! Thank you very much! I love Cascade peaks. One of the most beautiful volcanoes in the world. I did not had a chance to see any of these magnificent peaks. I hope i will one day. My country is far from any tectonic activity. And last ice age glassiers made sure that the horizon here would be almost as flat as a table. Although, I had some luck to see some of the Mexico's volcanic peaks. Such as Pico the orizaba, Popocatepetl, Iztaccihuatl, many small cones and Nevado de Toluca, which I climbed. It seems that it might have experienced an event, similar to Mount St. Helen's. It had lost it's peak and have a big caldera-like crater with lava dome in the middle and two lakes. I also noticed huge ash and what it seems a lahar deposits in the surrounding areas. Countryside roads are cut deep in these deposits exposing some layers of past eruptions. I wonder how it have looked before it lost it's peak.

Thank you, I thoroughly enjoyed this presentation. You are truly amazing

He is a fun guy to listen to and to watch his ways with the chalkboard. Priceless in a educator.

We need some geologist jokes: Geo1: "This is a glacial deposit" Geo2: "That's a lahar" Geo1: "I'm telling you the truth".

I don't recall you saying "mega" once during this presentation. Kudos for that.

What an awesome presentation.

God, Nick does a great job. Geology is fascinating even if it's no more than text on a page, but the Professor here kicks it up to riveting.

More videos by Professor Nick ,please. I just moved to Pa., found out there are earthquakes here too. Not often, but it happens.
