You know you're watching a teacher who knows his subject and loves to teach, when he's compelling enough to keep me up at 3am watching geology lectures on KZfaq. Multiple times. Not just a one time KZfaq clickhole. Nope. I think I've watched all of this guys lectures, at this point. Does that count as auditing a class?

This professor is so gifted. I am so hooked on this area of science now. I am 70 years old and learning something new! (retired RN).

I have been listening to these fascinating lectures and have decided to drive out to WA to look at this stuff. Thanks.

Seriously, this guy made geology rock!

I was going to go back and finish my engineering degree, but after getting hooked on Professor Zentner's lectures, I am seriously considering studying geology more formally, instead. Thanks a heap, Nick.

Thanks in part to this lecture series we are planning a vacation to Washington state, eastern Washington. We want to lay eyes on everything he is lecturing about. My wife has started training for the trail miles we will put in.

Thanks very much for making these lectures available to the world.

Give this man a nice, big lecture hall; let any student take his classes; and have graduate students manage his gradebook. He is a superb lecturer.

The irony is that I paused this video at 10:59 to see what was making my chair shake, and it turned out we were having a (quite mild) earthquake.

I watch Nick's videos closely, and not for the geology. I am a teacher, and I'm learning so much from his technique. I've taught anatomy for years. It's boring to most students, who only want a passing grade to get into their professional programs. Nick keeps people engaged by pointing out the boring bits. I want to try some of his techniques next fall :)

I had a teacher like Nick Zentner, Eduardo Msrtinez de Pisón. Seeing this one I´ve remembered his amazing lectures.

I live in Missouri. I lived up in Seattle for some time bout 10 years ago. What a great and fascinating state! I miss it very much! Nick, you are a fantastic teacher and have really piqued my interest in geology again!!

You are a really great teacher.

Great informative presentation! Many of us that wanted to study geology after retirement are thankful for your series.

I have listened to these lectures countless times . I even did a portion of a ice age floods trip in Eastern Washington to Missoula Montana I am such a fan I am fascinated by geology and wish Nick had information about every geographical place in the world ... he’s so good

I feel so bad for "Julie" 😥💜. Could've been me. Hope she passed the exam with flying colours and is having a great life! Big hugs for her 🤗🤗🤗🤗!

I am really enjoying these lectures. I lived in Rainier's shadow for the first 11 years of my life (I am from Tacoma). Interesting to hear about its history, so I am enjoying this one and the one about the Osceola mudflow.

This man can draw Washington state on a chalk board with his eyes closed. Love the old school artistry and presentation. It's a vanishing art among college science teachers.

Love the map showing the pacific rise, and what’s left of it in WA area, now called the ....de Fuca. The puzzle is coming together for me, I absolutely love Nick’s lectures!!

Unfortunately for me i live in San Francisco, however my aunt lives in Ellensburg and if i was there with her i would be taking this professor's class no question about it. It is so interesting to listen to the geology of our states. I wish i was in this course! Thank you for posting these lectures. They so interesting and he makes it so easy to understand, ...even for the non geologist! Bravo!

What an awesome service provided to the public to learn in such an engaging way!

This guy is a rock star. :).. I absolutely love these videos. No idea why. Just fascinated and its probably in the way he teaches. I live in Ohio with really boring geology compared to the pacific northwest. Keep up the great work!!

Serious, I want Prof. Zentner to post an exam we can take after bingeing his videos. I think we have earned at least a credit hour or two in geoscience. This is great stuff!

I actually like to learn geology when I can, your stuff makes me want to learn and expand my mind on this. It sounds minuscule, but it means a lot to me wish I could go to these lectures in person

Another great one! This is so valuable for the folks who are not students of geology per se but are potentially affected by geologic events. Understanding our environment is valuable.

"It's my lecture, damn it..." Just GO with that, Nick (as if you've done otherwise in all these years... LOL). I've prepared and presented college lectures... even as a student decades ago. I wrote and lectured in the mid 1980s on things I "got", for my classmates who didn't, and actually took up *teaching* (ugh) at a college many years later. It's your willingness and apparent talent to engage your audience *personally* in that way. I managed it with a few classes I clicked with... seldom. You seem to do it naturally, and part of my love of your videos is your being mensch enough to DO all this so the rest of us can learn :-) Cheers.

I love your way ! You do entice the mind. I share this with my seven year old granddaughter. She eats it up. Exciting. My daughter is faculty at U. Of A . Geology is one of her loves. Thank you , your planting the seeds of a wonderfilled journey through life.

Gifted lecturer! I guess I'm off down the geology rabbit hole!

I could watch your lectures all day. Fascinating!

My friends from Adak and myself were fortunate (and young/healthy) to summit Ranier in Aug 76. We went Northeast from camp Muir across the Ingram Glacier and across what I now know, as of a few moments ago. Across the top of the huge landslide. Thank you, Professor Zentner. That climb was a life-changing event, and now with continued ongoing knowledge. Here in central North Carolina,, boring by comparison, however, a much older topography.

Fascinating. After seeing Mt St Helens up close, this was an eye opening scenario. Fantastic presentation.

He forgot about the volcano, Mammoth Mountain may still be active in CA. It is on the western end of the Long Valley Caldera and the most southerly of possible active volcanoes on the west coast.. There is still a lot of volcanic phenomena in that area, especially hot springs and even a geyser they turned into a geothermal power plant. This isn't like the Cascade volcanoes, it's leftover from the LV Caldera. Mammoth last erupted with a steam eruption or phreatic eruption about 700 years ago. It's last full eruption was 57,000 years ago so some geologists don't consider it active because it hasn't erupted for 10,000 years, but since 1989 there has been a lot of activity and they are not sure why.

I SOOOOOO wanted to get your bit about "Julie" asking where the Cascades are, and another video where you showed a hippie for scale.... Classic! I've watched this video about Mt Rainier so often, now I'll remember it's the one with the infamous "Julie." I love screen captures!

Wish I had a teacher like Nick. I love this stuff. I'm home taking notes , thanks.very well done,sir.

I like Nick, All scruffy and into it. Very informative and Entertaining

Of the 4 visible buildings, is one of them multicare/TGH? I think it's second from the right. I love this picture. I was born right there. My family has lived there since just after we become a state and lived in Helena, MO for at least 3 generations before that. I love where we live and just wish we never forget the importance of our Salmon, Orcas, and Clams. We don't care for them and our mountain friends are going to hit the reset button much faster, I promise. We are extremely blessed. I'm so humbled by the entire area.

Fantastic presentation!

I just love this guy. Like Elizabeth, I'm hooked!!

I really liked being a tech instructor in the military. I endeavored to make things interesting with the main goal of learning the subject. I wish I could go back in time to use some of Mr. Zentner's techniques and style.

22:52 Poor little Julie, I love her, give her a hug for me

OK, just to answer the questions that some few will have - no - I am not that Julie. I do comment on several posts in here, so i am just putting this up here. Also, FYI, I am 67, with a degree in design so also not a geologist - but he is such an amazing teacher, I can't help but soak it up!!

The Dutch published in 1919 in detail what lahars are and what danger they constitute. Kelud erupted through her deep craterlake killing over 5000 people. The water had combined with ash, rubble and other debris. No one took any notice till the '60's. The Dutch put in a tunnel to lower the waterlevel in the crater.

Great Informative lecture Nick!! Loved it!! ❤

It makes me glad that Wharfedale, Yorkshire, England is geologically a nice quiet backwater. In 53 years I have felt two earthquakes. The last one woke me up about 4am circa 2009. I rolled over in bed, reached down and touched the carpet. The floor was vibrating. My mind went, meh, tiny quake...so what. I promptly turned back over and went back to sleep. I doubt I would be quite so blasé in other parts of the world.

Quite enjoyed this lecture, thank you!

The Geology of Mt. Hood, St. Helens, Ranier are very interesting. This region is also of major importance to an as yet Large Unidentified Bipedal Ape known as Sasquatch.

Very interesting. I don't understand why most people find history boring. I guess those people only live for the moment

Wonderful teacher Video BLAH

So when a continental plate moves over a sea floor spreading rift zone, the volcanism of the rift shuts down right? But why would this be? A hot spot doesn't shut down, it'll burn right through the cont. plate and a rift zone is tearing Africa apart. Why wouldn't the volcanism that causes the rifting continue to function under the cont. plate? Maybe this is why the SW USA has all those super volcanoes in almost clusters, the volcanism hasn't stopped but it can't "rift" apart the cont. plate so the magma builds up until it bursts through in a super volcano. Just an idea and my main question is why the rift zone would shut down when a cont. plate overriding it only affects the very top of the volcanism involved, especially when it seems that doing so would increase the rifting activity as more heat would build up over longer times (the overriding plate acting like a blanket).

if you're a Professor Znetner fan don't miss the film "Seattle Tsunami" with Dennis Quaid as Prof. Nick Zentner ... its earth shaking !

This is great. I just wish someone like him would cover the Great Lakes region, where I live.

Outstanding!

My desire to climb Mt Rainier has just withered and died.

Love this lecture

In describing valcanic mud flows you should use mount St. Hellens and the Toudle river

Why is there lightning when a volcano erupts like Saint Helen’s?

Thank you, sir!!!

Fascinating information.

Thanks for the note, Aroryborealis. Please be careful on your next adventure!

52:21 I think I saw that picture after Mt Pinatubo exploded.

I heard Julie is in Europe taking rock cores of the Andes!

Love it

Congratulations on your lectures! I 'm hooked! I have a question. Was Cocos plate also part of the Farralon plate or are the two plates unrelated? It seems to me as if North America has covered a protrusion of the Pacific plate (beneath California now) and now we see the Juan de Fuca and the Cocos plates as separate, but maybe once the were both part of the Farralon. Thank you in advance!

What I learned: They had sailboats 200 million years ago.

Great video series Nick, excellent presentation. Curious to know, what is likely to happen when the NA plate reaches the EPR? Any examples of such events around the world? Thanks

What is a Hoodoo? and how does it form? This is a question from an older friend.

Can you do a video about Louise H. Kellogg?

Lassen erupted just over 100 years ago. Of course it’s still active!!!!

It's my lecture damnit LOL

Recently found your lectures and am hooked. I should be working on projects around home but, can't stay away. So very interesting, learn so much about Pacific northwest I hadn't imagined. Thank you so very much.

Mr Zentner, I watch these videos and want to come up and take classes from you! Can you tell me if there is any correlation between the springing back of the NA plate with it's 9.0 quakes and the eruptions in the cascades? That is are any simultaneous? Thanks in advance!

I look at Rainier and think of Vesuvius.

Julie needs to reconsider her degree!!😀

I must say the production quality is so much improved in the newer lectures compared to this. But really, even back in 2013, the damn repetitive subtitle was annoying.

Poor Julie...

Is Pendleton, OR (the central focus of the circling NA plate movement), like Beacon Rock pluton, like the Cannon Beach ocean plutons, and this area was a massive single or multiple hotspots (as I was told) that this hotspot moved up the Snake River, and into Yellowstone. So there would be 2 major hotspot trails (WA/OR) and the NV lava beds up to Yellowstone. And that Pendleton area would be the real locations of multiple supervolcano magma chamber like Yellowstone, and this is what caused all the ~300 lava flows, as the Columbia lava basalts are not from the Cascades, let alone from the ancient volcanic sites. If Pendleton was a supermagma chamber and cooled like these other plutons, and far larger and cooled down, as the leftover chamber of the moving to Yellostone hotspot, then this would be a massive pluton that causes the swirling land circling around Pendleton. This pluton would be stable and stay while the upper NA plate swirls around this massive pluton spot.

If the lahars tend to follow river channels, then the additional threats of river divergences are equally life threatening and life changing.

It would be fun, one of these days, to sit down with yourself and Tim, along with a few Master’s Candidates, and discus those “Vectors” and your beliefs concerning the end of the Juan De Fuca Plate. I’m in your corner, by the way, though I’m of the belief that the timeframe may be closer to 7-8 My, with current mathematical models.

Those flows, hot spots, what if panega was moving over hot spots prior to break up?

No matter whether Pacific plate is dragging NW the JDF plate, eventually if the Pacific is moving faster (and JDF also), versus the NA plate going westward, then the Cascades will cool down and erode, as the subduction zone will reverse out and back into the ocean. If the JDF plate (Farallon plate) goes under the NA plate and moves extremely eastward, and subducts, then the Cascades will cool down, and erode. Either way, the Cascades will eventually cool down, then erode, as the original previous ancient (now dead and gone) volcanoes. One wonders whether the West or East WA (and OR lands) will continue to rise, maintain, or decrease and de-elevate with these 2 geological options, and we could get back into a flat land environment as in the most ancient past of lakes, forests, and flatland lava flows.

How do you date events....?

Anyone have an idea of who I'd take what I presume to be coral that is petrified BUT not exactly a fossil. I wish I could drop a picture

Hi Mr. Zentner, a question please; The East Pacific Rise is a spot where magma is welling up to create crustal plate? Is it an active upwelling force? Or is the magma just sitting there minding its own business, and rises/cools by simply getting exposed? I'm basically curious about the "drivers" in the mechanism of spreading centers, and what happens to that deep energy/magma supplier once their surface spreading centers get subducted. After all, the crust is just along for the ride, right? I'm in SoCal, so I'm curious about the the power source that was once driving the old plate, (now gobbled up) which is now presumably underneath us. What's it doing now? TY!

Can I assume that the Sutter Buttes(in the Sacramento valley) are a remnant of subduction caused volcanism and the Smartsville block as a section of the EPR scrapped off by the NA plate? And the hot spot around Mammoth lake? What's with that? So many questions! Sorry.

Interesting note on the Farallon plate and its long reaching effects - some theories point the cause of the New Madrid seismic zone as remnants of the Farallon pulling a weakened section of the North American plate (The Reelfoot rift, The Mississippi Embayment is a good "visual" representation of this failed rift of the NA plate) down with it as it sinks into the mantle. Earthquakes come when the NA plate springs back up. I just thought it was neat the same thing that created the Cascades could also be effecting geology 1000+ miles away.

If there's no plate pushing inward in central in southern california, why are the Sierra Nevada's rising?

I have a question about his time line though ... he says half a million years so roughly does this then the cascade formation is started roughly at the last eruption of yellow stone at 560,000 years ago?

"Ahhh, Geologists. The dirt people." Sheldon Cooper, 2016.

when will mt reiner ever wake up and when dawn

👍👍👍

Is the Farralon plate related to the Farralon islands?

Medicine lake in California is not a cone volcano.

Poor Julie.

Now I know why they turned off my ungulating local seismometer. The bear canyon station was recording long period undulations for months before they turned it off. Same reason gps reversed direction I think.

So what happens when NA plate hits the East Pacific Rise? I assume things will get very spicy?

@22:00 this story is hilarious

This 0ld Lady over Here wants to Iron your Shirt lol , Great Lesson . :) QC

As a science nerd, I love this geology series. But these were uploaded in 2012/13 - almost 7 years ago. You should re-upload these in a much higher resolution! I suggest 720 or even 1080p for those of us watching on 1080p or 4K monitors/TV's! And post higher resolution links in text for this AND the other corresponding videos! (PLEASE!)

Wonder whatever became of Julie?

Who would of thought! The world isn't "really" flat.?
