Dude... CWU, whatever you paid this guy, it wasn't enough. What an amazing, engaging presentation on a topic that could have very easily been boring.
He did many videos from home during the lockdown, go look at his channel, Nick Zentner
We love him here
Honestly, if this guy can make an in-depth, hour long lecture about rocks not only interesting, but entertaining at the same time, practically ad-lib, I'd pay the guy my year's salary to read from phone book.
@@wtglb Nick is awesome!!! Wish I had teachers like this, growing up.
@@azeers1975 I agree! I did have a few good teachers, but the majority were just going through the motions 🤷🏻♀️
4:26 in and talking Ghost Volcanoes… the geologist that spent 40 summers mapping out a single area that most overlooked is truly remarkable. 👏 Standing Ovation 👏
We have blast columns here in Ireland too. Called the giants causeway
Stumbled across these lectures about a month ago and cannot stop watching! Mr. Zentner is such an entertaining and gifted teacher. I'm quickly becoming quite knowledgeable on the geology and geological history of the Pacific Northwest and I live in Alabama! Bravo! Hope to visit my cousin in Spokane soon.
Nice comments. Thanks! Come visit.
I couldn't agree with you more.
Mr. Zentner, you have set the standard of teaching that I wish all other teachers would emulate. If I had you when I was going to school, I would be looking forward to going to school, not dreading it. Keep up the great work!
yeah I've been bingewatching prof zenter over the last 10 days. I'm a sucker for plate tectonics, end morraines, and especially maps. I wish his 6 part series had maps in it, but it was still very good.
Am hooked too :D Kinda binge watching haha
I would seriously attend lectures like this for fun (in a world where we can gather again). It's kinda nice to learn without having to take notes or an exam. I especially would love to hear geology lectures on where I live, in Utah. We've some strange geology down here, and a decent fault line too.
You should learning is continuous check your local college 👌
We can have that normalcy again IF enough people would stand up & refuse these BS mandates. I've been fighting then from day one, literally!!
@@burlfaulkii6496agreed, don't people understand that they can't throw us all in jail?
@@burlfaulkii6496 Constitution day is coming up (sept 17 oops) I always refer to that when people trying to give me their latest essay paper to read 📃 🙃
Qqqq away away
Nick is probably the most inspired and passionate Rock guy. Spent several years with my cousin here in Texas, and she is still an Environmental Geologist. She moved to Portland, Ore., earlier this year which was something she's been wanting to do since forever. Cascades are like a Geological Wonderland there She's in Rock Heaven up there

Can't imagine who disliked this video!!! Nick Zentner is such a wonderful educator, he's the teacher you loved and remember all your life. If I ever win the lottery and don't have to worry about supporting myself, I'll move from Canada to beautiful Washington state, throw a sh*t load of money at CWU and enroll in his class at the ripe age of 62. Thanks Nick, your passion is inspiring and you make we want to learn which is no mean feat... I really hated school (LOL) but love your lectures on UA-cam.
Memorable comments, Pearl. Thanks! Come visit.
@Cerberus ... what makes you think that a bible thumper would ever visit a site that has anything to do with actual education
Flat earthers and religious zealots. Look at any Hitchen vidyos. Same there.
Maybe disgruntled students who didn’t have the chops to pass the class!
@Cerberus I am a born again Christian and have been watching Zentner for about 3 years now. Don't be so ignorant about Christian's and God you'll one day meet. I LOVE learning about Gods creation!
Love that he is using a chalkboard
You have to love geologists. Several million tons of boiling rock and mud careening down a mountain at over a hundred miles per hour is "just a hazard".

I live in the UK. I now know more about the geology of Washington State than anywhere else on Earth. I'm really enjoying this lecture series.
Hello from America! Nice to hear. Thanks.
Keep them coming!
@@Ellensburg44 I'm also from the UK, although I did vist Mt Rainier 2 years ago. You inspired me to look at a geological map of where live, Edinburgh, and discovered my walk this afternon was on a hill made of andesite with views of a sill, columnar gabro, a volcanic vent and a neatly sectioned 350 million year old volcano. Thank you
I watch Time Team and know more about the UK's history than I do about the mountain I live on in NW Washington state!! 😁
This is the beauty of UA-cam and what we're capable of learning thanks to a platform like this haha
56:50 the columns look like the ones at Giant's Causeway in Derry, N. Ireland. Fascinating lectures!!! Go raibh maith agat!
I’ve lived almost 20 years in Washington (from France originally) and it’s only now through these lectures that I begin to understand our surroundings. Thanks to you professor Zentner! May you live a long life so we, the general public, get to enjoy your work and get a little smarter, a little more informed with each passing lecture.
Very nice comments. Thanks!
R G iiii
I'm only watching this because of all the wonderful comments of this lecture and it's teacher, professor . Lol
I've been watching these videos for a couple of months and have learned SOOO much! Fascinating! And YOU, Nick, make it so easy to comprehend and fun too...Thank-you so much... to you and all involved in making these videos and presenting them to us just for the sake of loving to teach those who love to learn...Bravo : )
Thank you so much for these videoed lectures- I love them so much. I share my interest in volcanoes earthquakes etc with my mother. Unfortunately, she had a massive stroke last year that has left her paralysed an unable to speak, though her intellect has been unaffected. I've been telling her about these lectures- I'm hoping I'll be able to take my lap top into the care home where she lives now, and play them for her. I knowshe'll enjoy them as much as I do!
Thank you, Carolyn. Best wishes to mother!
Go for it daughter! Love and prayers for you and your Mama!
My hope is that your students realize just how fortunate they are to have a Professor of your magnitude.. Ae 9+
I love Geological History. I understand everything this Man is talking about. And he is reminding me about certain details that I have forgotten about. I honestly feel* like I'm in high school again paying attention to what he is saying.
If Nick was a lecturer at my college, I’d be glued to my seat. Nick is the epitome of Teaching 👨🎓
You can sit in on his classes for free! They must be packed!
I would refuse to go home....more, more...
Watching these lectures makes me want to visit Washington. Thank you for posting this!
I lived in Southern California when Mt. St. Helens exploded. Even that far away, we got ash... not any measurable amount, more the consistency of a bad case of dandruff. But I remember that, and being kind of amazed at how far the ash had traveled. Love the lectures. 😊
We got ash in Calgary, Alberta, Canada. I was lucky in a way to have that experience.
Had ash on my car for days near Chicago. Incredible sunsets.
I. Lived in Monterey central ca. When st. Helen's blew we had crazy sunsets and enough dust you Easley right your name on are cars or any flat surface.
There where people arriving in there area trying to sell glass viles of ash.
@@jerryrichards8172 We lived in South King County and I knew instantly when that thing went off; not only bcuz we were expecting a major eruption at any time, but it woke us out of a dead sleep. But my dad was a dispatcher for a trucking 🚚company, and he had a re-route many of his drivers. The driver northbound I-5 out of Vancouver, Washington, thankfully stopped to scoop up some small spice jars with ash. I still have one
My family was camping on Mt Hood the day St Helen erupted. There was a hard shaking and what sounded like sonic booms and then it was as if it was night. 10 am could have been 10 pm by the amount of ash that fell over us. Needless to say we packed up and went home within the hour.
I was at Mt.St.Helens on May 18,1980.I was at the Cle Elm ranger station when the call came in.I heard the call and the young man died.We worked our way clearing the park.When the main blast hit,we were 75 miles away.The only thing between death was the driver side window and door.I have never seen anything like that.
I was on my way home to Longview with my parents following me..we pulled over to watch the blast! My boyfriend and I left for friend home in Boise, Idaho 9 days..no work for either of us! I Remember watching all the debris floating down the Toutle river...exciting times!
You actually heard the call David Johnston made?
“Vancouver. Vancouver this is it.”
If so wow. I was living in Spokane - I was only 4 but I remember the cloud and the blackout skies and all of the gray “snow” (I was 4!) that I wanted to play in. My dad said it took 3 weeks to clean just the roof. I still have ash my family saved and I’ve always been obsessed with St Helen’s and the history of the eruption.
If the extinct volcanoes are 'Ghost Volcanoes', then are the long quiescent volcanoes that may or may not be dead 'Zombie Volcanoes'?
Ha! Very nice!
That would work but they lable them as dormant and when found active active again.
These are the questions that keep me up at night
It seems to me, that the only truly 'extinct' volcano is a ghost volcano. All others merely await the right conditions to become active again. Like Mt. St. Helen's, and Fuego down in So. America, and I think Japan has a couple that just woke up again.l, and let's not leave out Mayotte, which birthed a new volcano underwater that sent a signature around the world in 2019. Volcanology...fascinating.
OK people, this is a date sensitive joke, it was 2018 and the big trend in the entertainment media was still zombies... just... dont take it seriously... you will hurt your brain trying to find something rational in things that are utterly lacking in any rationality.
Am I really being blessed with another awesome teaching video when Im still so thankful for yesterdays :), How fun Im so excited to start watching
Nice report. Thanks!
me too
Thank you for these, I really enjoy your insights. Plus I was a teacher for 30- years and I enjoy your personality as a lecturer.
Due to the lectures I know more about Washington geology than about my own living area in The Netherlands. Thank you Nick.
Hi Dick!
Basically it was underwater, now it's not...
@@bradbuster4102 Has anyone wondered what brought the US up from the sea lvl? Its more than just ocean lvl rise and fall, theirs another reason, Farallon plate went under and mantle with the plumes, super volcanoes and flood basalts had their part in it as well, back when and currently.
Dutch geology must be fascinating, though! A country that was largely reclaimed from the sea! Really astonishing.
Washington state geology is probably some of the most diverse and interesting one will find in close proximity, though. I love it!
I just moved to Washington, watched the Zentner series and now I know more about Washington than most of the natives.
17:47 "No way to rebuild itself, the putty is gone..."
No putty loves me.
Oh, here's a postulation, for why aren't there Old Lahars? Perhaps, because it's just mud, and that erodes easy?
MajorEVEfan 🤣
Lol
Ran across this by accident n. So glad I did.i have always been interested in geology and volcanoes n earthquakes. Especially the dormant ones that I discovered by accident about 7 years ago.i never realized the USA has so many😁
Great teacher👏👏👏
I remember when St. Helens blew. I lived in Seattle and in the shadow of Rainier for half my life. The thought of the lahars begat from Rainier blowing its top is rather terrifying.
Extremely
Stumbled across this lecture series while watching Geographics... I love these! So interesting, I think after I retire I'll go back to school to study geology!
These lectures don't concern my geographic location, yet; I still watch them.
I wish you were a Professor in my state ! That way I could find out how a giant sandbar got deposited on an ancient coral reef, Florida !
@@jimlangley840 I'm also watching from FL and have thought the same thing!
I would love to see you do learn more about, and do lectures on the south Cascades region between St. Helens and Adams, and talk about all the cinder cones, spatter cones, and shield volcanoes in the area. I am especially interested in the small cones and vents in the Indian Heaven volcanic field and the Mt Adams flank vents.
And how about central Oregon?
I hope, at my advanced age, if I get the chance to return to college, I can find instructors with the abilities this gentleman has.
This fellow is terrific, he has several videos on UA-cam.

He did live “Nick From Home” videos since the lockdown, they are great, go to Nick Zentner Channel
I am feeling extremely overwhelmed. I want to spend a month talking to this professor. I somehow had his lecture just auto start and I actually watched the whole thing. Wow am I a rock nerd. I am a Michigander and have an obsession with Michigan rocks and minerals. I am no geologist, only a true rock hound who loves the why to every rock I see. Early this month we traveled to the very small mountain range in the Upper Peninsula of Michigan. Some of the rocks that are regular in this region, looked very similar to the rocks that he had shown. I have so many questions!? How could this be so. I have always been curious to how some of our rocks being very porous and we have a black rock that is full of so many fossilized organisms ( like plants and shells) it looked like one he held up during one picture. I only have small pieces and they are rolled smooth by the lakes, unless you like to look elsewhere. We also have granite, basalt, diorite, quartz, shale, sandstone, mudstone, and so many more!! I guess I should just find a Michigan Professor that has the same passion for local geology as this guy does for Washington geology. 😄
I like the chalk-boards instead of the dry-erase boards. You can see them better. Why did people stop using chalk-boards?
because you have to wash them afterwards, otherwise the whole thing is vaguely cloudy white and the writing becomes unclear. When I was in college, there were some chalkboards where erasing just made it worse
Dust. Bad for computers. Nevertheless, I agree with you -- I HATE WHITEBOARDS. Chalkboards are far better.
Because they're huffing the marker solvents
Chalkboards threaten to deplete the world's supply of slate.
We were deep in a cave in the Marble Mountains and heard a hum
You'd think they'd move the Fred Meyer in Yakima, what with how many times it gets covered in andesite from goat rocks
A shout out to the incredible work by Portland State University geologists. Dr. Paul Hammond is the Volcanologist’s volcanologist. Tirelessly and relentlessly collecting data and putting out research like lava from a shield cone volcano. Bravo to Dr. Hammond and to PSU for being the hardest working department in the NW…at least when measured based on funding dollars.
I'm actually willing to do the school game again if THIS guy is my professor. My last 3 days have been brain packing unlike i have ever seen, and I haven't once lost the slightest interest. This man is gifted... I swear I am going to look into the university this next year of he is still there and I can get his class
I believe his Univ. lectures are open the public.
Accept Jesus Christ as your Lord and Savior and you will be saved. John 3:16 (share the good news of the gospel around the world!) Have a wonderful day/night, may the LORD bless you all, and farewell!,.,,,,,,.,,.,.
You're a mensch, Prof. Zentner (should that be "Dr?").... and you're *still* putting these talks on video, for which I'm eternally grateful. :-)
My little brother is the geologist (has been for almost 40 years), but we're both born scientists and I'm no more immune to geology than I am to astrophysics. :-)
May you continue with this stuff for as long as suits you best... and if my saying "Cheers, mate!" is any encouragement at all, maybe you'll continue for as long as you're teaching. :-)
Cheers, mate! :-)
Thanks for the encouragement, Michael. I enjoy putting these together. That people like you enjoy them is just frosting on the cake.
Thanks for watching, Michael. It's fun to put these together. Glad that you are enjoying them.

@@Ellensburg44 Sharing these with some of the locals living at the foot of Mt baker, to give them something to think about instead of COVID. Your lectures are some of the best i've seen (had to sit through a lot on different subjects).
I love this guy! Fantastic Professor! I have learned more about volcanoes in the past few hours than in 43 years of life. I would go back to school if he were my teacher!
If my image processing lecturer had had 20% of zentner's passion, skill and empathy as a teacher, I'd probably have gone into the field, let alone got a passing grade on that course :)
Thank you Professor Zentner, your style of teaching takes me back to my Jr. High and High School days. I had a couple of teachers that had a similar energy and style to yours, and for me those are the teachers who made the greatest impacts on my education. I consider you a Rock Star!!!
I have watched most of your lectures and find you most informative and entertaining - you are the best Nick please keep it up !! - I live here in Melbourne Victoria Australia and go hiking in the state we also have dormant volcanoes here but only on a small scale - you should try and get over here one day !! - PS I notice most of your audience are " mature ".
Most of today's youth are taking "Social" classes instead of "Science" classes. I went to college in the 60's and 70's. By the time I had to leave (military requirements) I had the classes to receive one B.S. but only the hard science for the 2nd B.S. I was so looking forward for that double major, but I lacked the elective "Social" classes for that 2nd B.S. Maybe that is why I'm not up to speed in the social life of today.
I really enjoy these lectures. Very interesting, informative, and presented very well by a dynamic and engaging speaker. I live in the Pacific Northwest and hike in the Cascades all the time, and will certainly look at them with a better understanding of their formation and evolution. Keep these films coming as they are great!
Appreciate the comments, Steven!
Absolutely fantastic lecture, Even though you think you know everything there is always something new to learn! It is practically endless which is why Paul has been at it for 50 years and is still making new maps, overall there is so much more of the story yet to be discovered like the recent proposed discovery that the lava chambers of Rainer, Hood and St Helens are all linked underground. If you live in Seattle like I do, get out there an explore. It is also good to note for people watching that while the subduction zone volcanos in central and southern California are long gone other volcanic systems remain very active such as the massive Long Valley volcanic field / Supervolcano, Mammoth Mountain which has actively gassing vents as well as the very very active Salton Buttes with its amazing mud volcanos and off gassing spatter cones, the western USA has volcanic activity everywhere you look. I think it is by pure chance that we are in such a quiet time in the history of the west so get out there and enjoy it as it is today.
33:18 hmmmm something sounds familiar (looking at u st helens)
Where is all the removed material from the ghost volcanos. The columns only seem to have a small falling away at the base of the cliffs. So many questions. Where are the source craters? I only saw ridges. The only tie appeared to be the rock type.
@Nick Zentner Thanks so much for this wonderfully fascinating presentation. I feel like I've learned something significant this afternoon.
I'd like recommend the software program RX8 by iZotope. its an audio restoration program for movies, dialogue, and music. you can clean up dialogue by taking backround noises out, and electrical hums and such.
Thank you, Mike. The student crew in charge of audio/video that year was not impressive.
Love to hear a lecture on Hawaii's current predicament and where all the lava is coming from considering its a hotspot sitting in one place with plate moving over it ! Why is it still active after all this time I mean to say why hasn't it cooled and run out of lava or moved on ) ! Regarding Ghost Rock lava flowing 50 miles instead of just a few could it have been due to ice !
Will add to my list. Thanks.
This guy, let’s call him Nick for now, has the unique talent of taking a mundane, dare I say..boring subject, an eye lid dropper at best, into a informative, engaging and entertaining lecture! The kind where 11:23 you walk away with a smile, a lot more knowledge than u had b4 and a warm fuzzy feeling in your stomach ( or that’s lunch kickin in, idk) a hallmark of a Great teacher who obviously cares about his subject and audience. Good job Nick, if indeed that is your real name! Ty
I can see the "ELK", at 32.08, on MT RAINIER right in the top middle of the picture! Can you see it? I can see the mountain from Auburn where I live. She last "blew" up about 5600 years ago creating the Osceola area in Enumclaw, WA according to what I learned from Nick Zentner. I now live in Auburn and can see Rainier from here. She has always been a part of my life! All 55 years of it!
In the Peruvian Andes, there's the Cordillera Blanca, no longer active volcanically like Cotopaxi, but nonetheless.very spectacular white granite spires with, yes, some glaciers and lakes, and condors high above for a special treat. Both southwards and northwards there are big volcanoes that aren't ghostly, like Aconcagua.
Nick Sentner always delivers the clearest info and with an interesting personality! He is smart and funny and leaves me with further resources to pursue! I I love his science based stories and the great visual evidence he is sharing with us. I am a blackboard kind of student, and appreciate his visual hand built pictures.
Dang it! Learning about the batholiths in the Cascades just makes me more curious about the older ones in the Rocky’s like the Bitterroot Range in the Idaho Batholith. I even thought I’d try to learn about the geology of Butte Montana because of all of the mining, and while I’m happy to say I understood more of what the one Geology video I could find on the region was telling me because of watching Nick’s videos, it’s sad that they weren’t as entertaining as Nick’s videos are. Can we clone him because he makes Geology fun and interesting.
Very interesting presentation! After watching this, my next step will be to view the west coast of the Americas from Google Earth.
Watching your lecture was fantastic. If I had instructors like you I would have finished my degree or two.
This video is always in my recommendations, glad I watched it, I'm from Yakama or Central Washington
THANK YOU so much for making these presentations available!!!
Why do the volcanoes stop when the pacific rise goes under NA? You would think they would be hot spots under the continent like Yellowstone. Is that spreading center plugged by the mass of the continent? Is North America riding over the Pacific Plate or are they going along at about the same rate? By they way thank you so much for your videos. I live in Oregon, first in Hood River and now you've explained the Columbia River Gorge for me in several of your lectures. I think I'm out of your videos again.
Thanks for watching. Stratavolcanoes like in this lecture are only from subduction of ocean plates. Hot Spots like Yellowstone make a different type of volcano - so not part of this lecture.
To answer your question, yes, there are a number of hotspots / former hotspots under the NA continent, such as the Anaheim volcanic trail in BC and the Raton hotspot/Jemez Lineament in NM, and evidence of other hotspots that are no longer under the continent like the New England hotspot. Also there are a number of other volcanoes that are related to the Mid-Tertiary ignimbrite flare-up.
The subducted active spreading of the East Pacific Rise may be partially responsible for the crust extension in the Basin and Range province. Look up the "slab-gap hypothesis" for more information.
Nice to see some positive WAstate history.
Nice to know MOUNTAINS last longer than rioters!
God did some beautiful work making volcanos, plates. Everything in geology shows the care God has taken to show historic details.
Great to see you adding some new lectures... I have just about worked my way through the older ones now! Like the other poster below, I am a Brit, although I now live in Pennsylvania, but I know more about the geology of Washington now than anywhere else I have ever been! I did spend a few days in Yakima back in 2001 while on a road trip, but I wish I had known this stuff back then!
Thanks Phil. Come back and visit!
Pennsylvania has some strange and fascinating geological and geologically-adjacent (to borrow the parlance of SoCal real-estate agents where many parts of town are "Beverly Hills-adjacent" despite their generous distance from those hills) stories in its own right. From the glacial influence and extended plateaus to ringing rocks and megaliths plopped down right in the middle of the woods to the cautionary tale of Centralia, geological oddities and mysteries figure prominently in that state. Regardless, I second Mr. Buglass' appreciation for the lectures. Truly fascinating stuff coming from a natural-born teacher. As we're apparently "ahead" of the Northwest, geologically speaking, I only wish we had an analogue to Mr. Zenter down here in SoCal.
such a wonderful video! I've watched it three times! But boy, oh boy, UA-cam is a shadow of its former self, as we all cringed with anticipation of January 2020.
It was my good fortune to grow up in a home filled with books on a variety of subjects. I had exposure to many things and from that exposure, I could supplement my learning through books from the library, or documentaries on TV.
I couldn't activate notifications for this channel, hence my complaint to my complaint to wacky YT:
"Why on Earth would you make unavailable to children, participation in a fascinating presentation about Earth science?? I'm sure glad I didn't grow up in an environment that interfered with this sort of wonderful learning. Also, as an adult I resent not being able to activate the subscription notifications."
I can appreciate there may be some videos they want to prevent children from seeing, but to stop them from being able to like, save to a playlist, or activate notifications of educational materials is ludicrous.
Great presentation Mr. Zentner !
It is better than any TV entertainment ! I am a true fan of yours !
Please keep them coming !
Thanks much for the encouragement!
I just listened like a kid around a campfire--I'm a three time hiker to the summit of Whitney and this whole time I had no idea I was on top of a granitic batholith on a GHOST Volcano! How cool was his presentation?!? Kudos just an amazing speaker.
Dittos
Had I met you when i was in college I'd be a Geologist. What a wonderful group of videos and lectures I get to enjoy! Thank you!
This guy is amazing at what he does. Great presentation.
OOPS, I mean all 65 years! I goofed!
You'll find plenty of ghost volcanoes, flows, and calderas here in Idaho...most flows never having developed cones at all. The other end of the Southern "smiley face" valley on a topographical map of Idaho is Yellowstone. The Continental plate travels over the stationary magma chamber, which is currently under Yellowstone, but is what formed our valley that I-84 and I-86 were built on. Craters of the Moon National Monument is a great place to learn about it.
We have one requirement for attendance at this seminar. No exceptions will be made. Your hair color must meet the University's mandatory requirement or you will be exempt from attendance.
Yakimaaaaa more emphasis on the ma.🎉 Brilliant lecture thank you! I'm living in N.E. Oregon right now about 5,000ft at the foot of Wallowa Lake. My yard has sunk and now has a noticeable slopping. I have no idea why? It started sinking last fall. Anyone else notice this happening? One other person noticed her yard developing a slop as well. She's on the other side of town. Very weird. I was eight when Helens blew.
That explains why Wisconsin has alot of granite
and cactii
The town of Portland, Oregon does have most of a Pliocene-Pleistocene volcanic field within its metropolitan boundaries. The Boring Volcanic Field consists of more than 80 cinder cones and small shield volcanoes. The youngest volcano (Beacon Rock) in the Volcanic Field erupted about 57,000 years ago.
Everyone talks about stratovolcanoes being active in the Cascades.
What about the cinder cones, spatter cones, and shield volcanoes in the Cascades between the south Cascades of Washington and all of Oregon? There are tons of these features down here in Oregon.
Are events like that still possible today? Can we still see lava flows, cinder cones, and spatter cones erupting in the Cascades today? What is the likelihood of such an event happening again today?
There are some absolutely massive lava flows in the Cascades, such as the Big Lava Bed in southern Washington, the three major lava flows on Mt Adams (A.G. Aiken, Takh Takh, and Muddy Fork), the many lava flows around the Three Sisters, the Brown Mountain lava flow in southern Oregon, and the Belknap Lava Flow in central Oregon.
Great comment ....I grew up in Bend,Oregon ....Lava Bear alumni.....Im wondering what he would say about "hole in the ground" is there a new or different theory of its formation.... My jr high teacher said Pilot Butte on the edge of Bend would look like Devils tower in Wyoming a million years or two....lol.....but your thoughts have me now wondering about alot of places in Oregon!
In Bend Oregon and Surroundings,Lava Lands Cinder Cone,Pilot Butte Cinder ConeMt.Bachlor, 3 Sister's, etc.What About Them?
one in Vancouver Canada... we call it Queen Elisabeth Park.... in the city
I've got a question that has been bugging me ever since I watched this most excellent lecture. If the Farralon and Pacific plate were moving apart, and the reason the Cascades go quiet in the south is because the North American plate has completely overridden the Farralon plate, what is the relationship of the NA plate to the Pacific plate, in the area where this overtaking has taken place? Has it shifted over (no pun intended) to the strike-slip fault as it is further south with the San Andreas Fault? Just wondering.
If that andite flow made it all the way to the Fred Meyer in Yakima 1.4 million years ago does that mean Fred Meyer has been in business all those years WOW😮😂😂😂😂😂
Fantastic and thanks for intelligent content.
Great geological history lesson, alot of information to obsorb, but a goid beginning, very enjoyable presentation, hopefully someday I'll make up into that area, do a bit of hiking and cramping, thank you
Was a 4.4 in Oregon in the Cascade mountains today but not near any marked fault nor marked volcano. Interesting quake was 14km depth.
Dose anybody know how or if the wallowa mountains in Oregon are somehow geologically connected to the cascades. The wallowa are isolated to the east of the cascades and iv always been curious. There is alot of quartz and granite up there. Maybe it's a batholith. This is so interesting:)
I would've swore he was talking to a room full of college kids until I saw that everyone in the audience has Gray hair🤦♂️🤦♂️🤦♂️🤷♂️🤷♂️😂🤣😂🤣 Same with his last video I watched too on the giant fault line off the coast of Washington line off the coast of Washington
I find his way of explaining geology fascinating. This subject could easily (due to its complexity) be boring.
Hi I am from St. Marys, Ontario, Canada and I am wondering if by chance the Canadian Shield could be a 'Ghost Volcano 🌋"?
PS I absolutely loved your lecture, very interesting and also very informative.
Sierra Nevada Mts are an accretion plate (Laramide Orogeny) so I woulds think the volcanoes preceded the Sierra Nevada.
Also to be a good geologist the USGS must not hide reporting earthquakes (or downgrading the larger magnitude ones) and fissures that occasionally open up, shoot some lava and start forest fires (supposedly started by 'lightening' on clear days with not a cloud in sight)
Thanks for watching. This business about the USGS hiding information is ridiculous.
Nick Zentner not at all
Did you have a geology moshpit???
