Nick NEVER disappoints! These lectures, in my opinion, are pure gold. I can't praise his ability to educate us all enough. As I have said before, this man is a force of nature in and of himself.
The quality of your lectures, compared to the first lectures to now, Nick are just fantastic. It's so much easier to see the blackboards, audio is much better, overall just outstanding. The content of your lectures is always fascinating. I'm studying B.Geoscience in Australia, I hope to come to Washington one day. Keep up the fantastic work Nick.
How surprising was that link between Oz and the US in that other lecture. Tickled my geology fancy that eh. Have been fascinated by some of the geology in the Helidon Hills just west of Brisbane so was quite intrigued at this link between our two continents. Would love to find out more.
I was so very impressed with the story of Professor Beck and his contributions to the science of Geology. That he was also a Professor of Music at the same time makes him a true renaissance man. BTW: NickZ rocks too!
Ray Norman I concur. I'm a bit unsure of why that beautiful mural is hanging there in a spot where it could be spoiled if people rest their heads again it.
I'm retired at 61 and Prof. Nick's lectures have been a great use of my time while staying isolated. I just wish there was someone doing something similar on the east coast since I live in PA but we don't have nearly as interesting "active" geology over here.
@@scottyV1000The geologist Myron Cook has a very interesting YT video about the creation of the Appalachian Mountain Chain. Each state's department of natural resources should have a website showing what's on and below the surface with links to the USGS, universities and mining organizations that can provide more detailed information.
Amazing! everytime I listen to you I am just enthralled.. If I had had you as a teacher when I was a lad I probably would have ended up a geologist.. I live in vancouver washington and hope that soon I can make a trip back to your area and at least catch one of your lectures.. I am not is such good shape these days but I might even try to go to some of these wonderful spots you have mentioned just to see the geology of it all.. To look again at the surrounding land and to know it's history, to envision what it must have been like.. How thrilling it seems to me.. even now I remember so many of the places I have ventured to, here in the pacific northwest.. and with the eye of understanding (which you have brought to volition in me) I see it all anew.. It is a good thing, when at older age you find new things.. The world kind of becomes old and familiar the older you get.. not as in the days of youth when all things are new and out there to be discovered..Thanks Nick you have a talent that is amazing and I am glad to see you using it to benefit so many others.. May God bless you in ways that thrill you!
I am sure that George Beck would be pleased with his grand son passing the journals on where they can be preserved and appreciated. Thanks for telling the story and Thanks to George Mitchell for not trying to monetize his inheritance.
As a child growing up in the PNW this info would have been so precious. It makes me happy future generations have equal access as the rich folks who can take courses and such. I hope this remains free.
Nick, the word WIZARD comes to mind as I finish your second lecture of this series. I am ready to move to Washington for my rock hound fix, and I am a Wisconsin lifer at 70 yo. You enliven me in so many ways as you dance across the stage full of information, geology at its BEST. Thank you ever so for being yourself in public.You Brave Wizard You
I know where you can get those huge palm fronds, like the ones hanging in the museum today. I ran across a couple dozen of them deep in the woods, along with hundreds of fossils around the 1s.f. size. They are "near" the 2009 land slide at race horse creek, but they are not from that slide event.
Hey, Teach: Muffler Boy can’t hold a candle to…BOW TIE MAN! Only took me maybe 6 complete viewings to coin that bit of silliness. Love ya, and thanks a million for all of the knowledge from all of talks and classes you have so generously shared with all of us in TH-cam Land. Ciao, bella!
marbleman52 that’s what I’m saying!!! Being born and raised in the NW spending much of my time outdoors I’ve learned so much from Nick through all these series videos. Would love to see one in person!!
If I were a geologist or biologist, this would be most certainly a lecture I would not want to miss. If I were a theist I would be most certainly disturbed by many of facts learned here. As I am none of these I can just lay back (while knitting a sweater) and marvel at the unimaginably long string of violent as well as microscopic events that took place on our living and kicking planet. If any of them had not happened or happened differently most certainly we would not be here to be fascinated by this. This lecture is a jewel.
I got head to toe goose bumps when he visited the grandson of George Beck. I think I would have passed out seeing all those journals. What a find. Thank you Nick for your research skills and perseverance to find what you share with us.
I dont live in the Northwest or even America or the Northern Hemisphere for that matter but have watched probably 50 of these lectures and am familiar enough with the material to follow and sometimes predict what the next reveal might be. Watching these has now made me watch a number of Documentaries on the geology and ancient history of my own corner of the globe Eastern Australia. I have never been interested in Geology or related fields beyond the excitement of Volcanoes and now I am. My point is it takes a special ingredient to state someone not interested in a subject and get them to be so and that special ingredient is a rare thing, A good teacher! Well done Nick
Over the years, I have visited many of these fascinating places. I really want to revisit them now with "new eyes" thanks to these lecture series over these past years.
Thanks for posting this. When a graduate student studying Anaplasmosis with the Agricultural Research Service I was tending rodent traps out in the Owyhee Mountains looking for baby ticks on the rodents, actually, when trying not to fall down on the uncertain footing found a leaf fossil sticking out of the ground. Looking around more I found two others which I collected and heretofore was unable to place in geologic time. Thank you!
I salute you Nick for your fantastic lecturers!!! A+ 👍🏻😊👊🏻 I’ve been watching from Guadalajara Mexico the past few years where I have lived in my 50s (first comment) when I’m bored and have time...definitely some of the most interesting viewing on utube imo being from Washington and living between Seattle, Kennewick and Spokane due to parents divorce while graduating from UW in business 30 years ago. Sadly never visited the Burke Museum as a student in early 90s but our entire state has fascinating geology and you sir are a great lecturer! Great content and thanks to CWU too! I’m a huge fan of you and your work, as well as those that help you provide us viewers interesting lectures! Gracias John:)
Love the content. University in my phone. I’m an engineer but this content really broadens my knowledge. Thanks so much for ur dedication to sharing your life’s work
This is a great series of lectures from which I am learning many new things. I was aware of the "56 High" and thought that was the thing that made palm trees thrive that far north, but did not know when it happened or how long it took to build up, or that it is called PETM Now I have an improved understanding of some of the forces involved. It is great to live in a time and place where almost everyone, regardless of class or social distinction, can have access to such educational material.
Sure am glad I found this channel. I went to college just for the very in depth geology that you can't find in a public library. Don't need to join college now!!!
Great job Nick. I'm slowly getting through all of your video's. I would love to see any info you have about the shifting around of the African plates and the tearing away of the northeast area. Thank you brother. Always a fantastic job you and your whole crew do.
These lectures are thoroughly fascinating! They really make me want to go to Washington and explore it! Heck, I might need to move there long enough to take his entire class.
Nick, your lectures are awesome, i love them so much and I'm from Montreal, Qc, with no geologic background whatsoever, to give you context, nothing could be further from my everyday life than this, but you make it very interesting and always enjoy them, i know more about the pacific northwest geology than most Washingtonians do i bet :) ...anyhow, got into this over interest in the last ice age effects on our planet, and being that here in Qc, we have the oldest bedrock, our vallee was a flood plain from those days, it is evident on google maps, so all of this actually does have meaning to us in this part of the continent, with all that ice on it scraping away past geologies, glad i got into your series, watched every single one (lost hammer in the cracks was a highlight :)) you and Randall Carlson have a lot in common on this subject, maybe a little meet-up would be appropriate (if you don't know him already) anyhow take care buddy, and know you are a great teacher, wish i had geology with you when i was young ;)
The thing of it is I see mostly all people in there , but my goodness this is interesting . We need to learn about the past so we can better understand the future .
Excellent lecture, comprehensive and interesting as always! Apologies this comments is a few years late, but is there a link anywhere online to that amazing animation starting at 40:18 showing continental drift throughout the Epochs? Noting that there is a CWU logo in the lower right corner, so presumably it was developed in-house? Here's an idea if you haven't thought of it already: Develop a 'sequel episode' overlaying ice sheet advances and retreats along with rising and falling sea levels, in particular showing how little land area is left un-submerged during the PETM, i.e. when both polar ice caps were melted, with perhaps a sidebar graphic showing estimated atmospheric CO2 concentration. Now that would be BOTH a real mind-boggler AND a valuable climate-policy public service!
Variety is important--vary media, vary focus on people and types of stuff, vary between hard and ready, vary between serious and funny--but keep your focus by including language that provides explicit transitions, connections, and time relationships.
There are no logs in the vantage sediment because they float! The pumice, too. So after each lahar a graded sediment layer falls to the bottom of the lake but the logs remain on the top. Your petrified logs are therefore, probably, from all the lahars....maybe mostly the later ones if the earlier ones rotted away.
Another great lecture Dr. Nick! One thing I had heard at John Day Fossil Beds in reference to those warmer times (not just the PETM) during the Paleocene/Eocene was due to a warm ocean current running up the eastern Pacific from the south (like the Gulf Stream brings warmth to the east coast and the UK). That current eventually petered out or moved, where now a cold current runs down from Alaska to Washington and Oregon. That change in climate is reflected in the fossils as they transition from semi-tropical to cooler climates from 51Ma to about 5Ma. But is that the new thinking about the transition from warm to cool?
Love this stuff, I know exactly where you are talking about. I have lived in WA all of my life and very much love the geological history of this state. Very busy.
Holy crap. I have noticed several things like you have mentioned about the fissure. You have answered my questions. I grew up in the Columbia gorge and have always imagined the forces that caused these geological forms.
As a kid, living in Selah in the '60s, I was in the Boy Scouts. I don't recall exactly where we were, but my Troop was camping in the mountains west of my area. I was always interested in geology and had an extensive rock collection, and always had my eye out for new specimens. I picked up a strange rounded rock about two inches in diameter from some gravel near the small river at the site, but had no idea what it was. Back home, I took it to a teacher, who could also not identify it, who then sent it to a friend of his in the profession. It was determined to be petrified camel dung. I donated it to that teacher. Now, I live in south central Idaho. Four years back I found petrified cactus of the genus Cereus. I presented that to my father as a gift. He lives in Moses Lake and had someone at WSU examine it for confirmation. They were amazed, as was I. Thank you very much for your informative teachings. I am a fan.
OH yah; good to see Hank showing up here. I recognized the voice before the face LOL. Nick's gotta know him; Hank teaches at U of MOntana in Missoula IIRC.
There is a massive plant fossil deposit not far from me in Clinton BC Located right on the side of the road. The fossils are encased in a very white brittle stone.. Love to hear Nick's take on it...
Dear Nick, yet another fine presentation, thoroughly enjoyable. Somewhere about 2/3rds through you were using an animation that had the history of the continents on a time-line which you can slide to show the state of the globe at any time in history. Is that animation in the public domain? I would love to add it to my collection of interesting files. Cheers.
As the PETM was quite short the expansion of palms to extreme lattitudes was very rapid, sea currents and colonizing costal margins I can understand but was the expansion overland as well a I cannot easily see a mechanism for dispersing nuts at the required speed? eg Even a 1000 km advance of the forest margin in 100k years is 10m per year , and if a tree take 10 years to mature the the steps are less frequent but need to be greater ie 100m per generation. Nuts in my mind are not associated with wind dispersal . I remain curious. Great lecture thanks.
All those exotic terranes were part of those earlier Central and South American islands that were in those equatorial locations, and fossilized down there, and moved northward in later times.
If a lahar brought the logs to Lake Vantage, would the volcanic particles settle out of the water before the logs became so waterlogged to sink? Would this explain the graded bed in the Vantage sediments and the logs above?
As always, I'm impressed with the amount of detail and evidence presented by Professor Nick Zentner! Thank you for yet another brilliant and informative video! Unfortunately, I can't find many plant fossils around south-central Wisconsin. But on April 20th 2019, I did find my 3rd and largest "Honeycomb Coral" fossil fragment, weighing 120.1 grams! Contact me, and I'll send you photos of this specimen, and some details to where and how it was found. Thanks again, and be safe! I'm looking forward to your next video/s!
I'm curious, if some lava flows have pillow lavas and some don't has anyone done any temperature testing to see if temperature is the cause of the difference? I can't see any other cause for the difference.
For those of us who have never taken a geology course…. This is like opening a Pandora’s box of unfamiliar, strange and wonderful information. I think we all suspected that someone, somewhere had been studying such things…. And now, here it is. And even within this tsunami of information… the fact remains that this is all just the last 100 million years of a 4 billion year old planet!
Question: Given that: 1. The wood was found IN the pillow layer, 2. The pillow layer was HOT enough to burn the wood, 3. The wood did NOT burn up, 4. There are LOTS of types of wood in the pillow layer, 5. The wood must have been water-logged, COULD IT BE that the wood did NOT come from the lahar that immediately preceded the pillow layer (part of the same flow), but rather, a previous flooding event (perhaps a mud slide) that soaked those logs, THEN the pillow lava came in froze the wood in time? ... please correct me if my reasoning is wrong, or if I got information scrambled.
Yeah, that is definetely a possibility. If that was the case, I think there was likely a short amount of time in between when the first flooding event (mud slide) swepped the trees into or near the lake and when the lava came and ultimately buried them. That's because if they were originally swept onto land by the lake, they would degrade over a hundred years or so exposed to the air, and if they were swept into water and a bunch of time passed, they would be buried by other types of lake sediment, and the lava would have flowed on top of logs+sediment as a seperate layer. That is, of course, if the lava flow didn't rip the logs out of the sediment, which might be a possibility too.
just one question, how do they know the logs were not already petrified and they were not moved in a petrified state along with the lava to end up there?
Just curious.... have you ( Nick) heard of the expanding earth hypothesis? Wind could have blown Australia, china and Siberian sand into west coast. I know its hard to explain where the extra volume is coming from..... besides that. Can u make an un biased video on the pros and cons of the theory? It is important to hear opposing theories as well as the accepted theories. Btw. Love your enthusiasm and geological expertise. I listen to your lectures all day while i work!!!! Thanks and keep em coming!!!
@@annaakesson2413 Aah here in India..people are just buzy with their jobs..posting such lectures is nearly impossible for us here..but whenever i find such i will link here.
Professor, I believe the trees were drowned by prehistoric lakes and water logged which would keep them preserved and on the bottom, the the ginkgo flow would've flowed towards the water cooling as it flowed into/on to the lake cooling on top of those logs!
Nick NEVER disappoints! These lectures, in my opinion, are pure gold. I can't praise his ability to educate us all enough. As I have said before, this man is a force of nature in and of himself.
Wonderful lecture. Unbelievable find of the Beck journals and ledgers. What a gift to knowledge of Washington State.
Nick deserves an award for procuring those journals. That is outstanding! George deserves to have something named for him as well for donating those.
The quality of your lectures, compared to the first lectures to now, Nick are just fantastic. It's so much easier to see the blackboards, audio is much better, overall just outstanding.
The content of your lectures is always fascinating. I'm studying B.Geoscience in Australia, I hope to come to Washington one day. Keep up the fantastic work Nick.
How surprising was that link between Oz and the US in that other lecture. Tickled my geology fancy that eh. Have been fascinated by some of the geology in the Helidon Hills just west of Brisbane so was quite intrigued at this link between our two continents. Would love to find out more.
The Pacific Northwest of the USA is very young and dynamic compared to much of Australia, eh?
One amazing video after another. These really help me keep my brain ignore the pain. Thank you.
The same for me!,
Priscilla Ross-Fox same here!
Agreed !!!!!!
He's a great teacher. I have trouble paying attention and he keeps me engaged all the time!
I was so very impressed with the story of Professor Beck and his contributions to the science of Geology. That he was also a Professor of Music at the same time makes him a true renaissance man.
BTW: NickZ rocks too!
Ray Norman I concur. I'm a bit unsure of why that beautiful mural is hanging there in a spot where it could be spoiled if people rest their heads again it.
I like it because it expands my knowledge from the Gulf Coast strata to the west coast and Pacific North West development. I'm 72 and still learning.
It's critical to keep learning. When we stop learning our brains rust.
I'm retired at 61 and Prof. Nick's lectures have been a great use of my time while staying isolated. I just wish there was someone doing something similar on the east coast since I live in PA but we don't have nearly as interesting "active" geology over here.

Second time through for me....lol
OMG OMG OMG!! Its here!! ..2nd Lecture!
I am sure that George Beck would be pleased with his grand son passing the journals on where they can be preserved and appreciated. Thanks for telling the story and Thanks to George Mitchell for not trying to monetize his inheritance.
I can listen to you talk all day. Learning so much from your lectures
Yay!!!! New Nick video!!!! Life is good. Thank you sir!
This series is reason enough to watch youtube incessantly. Late comer to geology here in Prescott but this guy is great.I may becoming obsessed!:-)
Harry Haff I’m addicted. I can’t stop watching them.
Prescott like in BISCUT? Go north to Johnson canyon between Williams and Ash Fork, on west side.

If you enjoy Nick's lectures, I hope you have followed his "Nick At Home" and "Nick on the Fly" and "Exotic Terranes" series this year.
Amazing stuff. The hero is Nick Zentner for persisting in his pursuit of George Beck's journals and memorabilia.
Nick Zentner could just as well teach the art of public lecturing... which for the most part is a lost art. Bravo.
Over the years, I have visited many of these fascinating places. I really want to revisit them now with "new eyes" thanks to these lecture series over these past years.
Truly value your talks, Nick. Well done!
Seen the stuff he's been doing since COVID? Awesome!
For me, Nick Zentner is right up there with public educators like Carl Sagan and Neil Degrass Tyson. An educated public is our future. Wonderful!
Neil D Tyson? A corporate/Government shill. A liar.
Another excellent presentation. Thanks from Australia 😀
I found a crinoid fossil by cracking open a slab of sandstone, here in Pennsylvania 👍🏼Rocks are awesome ♥️♥️so are you Prof. Nick 👏🏼👍🏼👍🏼♥️
I found some fantastic complete vertical tree trunk fossils in the bottom of a coal mine in Ashland, PA along with an autograph of Scott Carpenter.

Back home, I took it to a teacher, who could also not identify it, who then sent it to a friend of his in the profession. It was determined to be petrified camel dung. I donated it to that teacher. Now, I live in south central Idaho. Four years back I found petrified cactus of the genus Cereus. I presented that to my father as a gift. He lives in Moses Lake and had someone at WSU examine it for confirmation. They were amazed, as was I. Thank you very much for your informative teachings. I am a fan.
Nailed t dead on!! Amazing,. Thank you from Oregon.
What a great lecturer on an interesting subject!
Yay Mr Nick is back!!!
OMG I'm geeking out! You got Hank Green in your video! That's huge!
OH yah; good to see Hank showing up here. I recognized the voice before the face LOL. Nick's gotta know him; Hank teaches at U of MOntana in Missoula IIRC.
There is a massive plant fossil deposit not far from me in Clinton BC Located right on the side of the road. The fossils are encased in a very white brittle stone.. Love to hear Nick's take on it...

Pumice maybe?
Dear Nick, yet another fine presentation, thoroughly enjoyable. Somewhere about 2/3rds through you were using an animation that had the history of the continents on a time-line which you can slide to show the state of the globe at any time in history. Is that animation in the public domain? I would love to add it to my collection of interesting files. Cheers.
As the PETM was quite short the expansion of palms to extreme lattitudes was very rapid, sea currents and colonizing costal margins I can understand but was the expansion overland as well a I cannot easily see a mechanism for dispersing nuts at the required speed?
eg Even a 1000 km advance of the forest margin in 100k years is 10m per year , and if a tree take 10 years to mature the the steps are less frequent but need to be greater ie 100m per generation. Nuts in my mind are not associated with wind dispersal . I remain curious.
Great lecture thanks.
Animal dispersion?
Another great video. Thanks for posting.
Good job Nick. I put it out on my FB.
Inspiring, thank you Nick!
All those exotic terranes were part of those earlier Central and South American islands that were in those equatorial locations, and fossilized down there, and moved northward in later times.
If a lahar brought the logs to Lake Vantage, would the volcanic particles settle out of the water before the logs became so waterlogged to sink? Would this explain the graded bed in the Vantage sediments and the logs above?
As always, I'm impressed with the amount of detail and evidence presented by Professor Nick Zentner! Thank you for yet another brilliant and informative video! Unfortunately, I can't find many plant fossils around south-central Wisconsin. But on April 20th 2019, I did find my 3rd and largest "Honeycomb Coral" fossil fragment, weighing 120.1 grams! Contact me, and I'll send you photos of this specimen, and some details to where and how it was found. Thanks again, and be safe! I'm looking forward to your next video/s!
Doesn't the genko tree feature make sense if there at the bottom of a lake when the flow covered them?
I'm curious, if some lava flows have pillow lavas and some don't has anyone done any temperature testing to see if temperature is the cause of the difference? I can't see any other cause for the difference.
Great lecture, thanks!
This guy is a gifted communicator.
The neat flat ends of the logs are curious. They look as though they were chainsawed off. What process achieved that?
...the process is commonly known as 'using a chainsaw'... ;-)
Nick is GREAT!
YES, another video
Do you sell tickets sheesh
For those of us who have never taken a geology course…. This is like opening a Pandora’s box of unfamiliar, strange and wonderful information. I think we all suspected that someone, somewhere had been studying such things…. And now, here it is.
And even within this tsunami of information… the fact remains that this is all just the last 100 million years of a 4 billion year old planet!
Question:
Given that:
1. The wood was found IN the pillow layer,
2. The pillow layer was HOT enough to burn the wood,
3. The wood did NOT burn up,
4. There are LOTS of types of wood in the pillow layer,
5. The wood must have been water-logged,
COULD IT BE that the wood did NOT come from the lahar that immediately preceded the pillow layer (part of the same flow), but rather, a previous flooding event (perhaps a mud slide) that soaked those logs, THEN the pillow lava came in froze the wood in time?
... please correct me if my reasoning is wrong, or if I got information scrambled.
Yeah, that is definetely a possibility. If that was the case, I think there was likely a short amount of time in between when the first flooding event (mud slide) swepped the trees into or near the lake and when the lava came and ultimately buried them. That's because if they were originally swept onto land by the lake, they would degrade over a hundred years or so exposed to the air, and if they were swept into water and a bunch of time passed, they would be buried by other types of lake sediment, and the lava would have flowed on top of logs+sediment as a seperate layer. That is, of course, if the lava flow didn't rip the logs out of the sediment, which might be a possibility too.
just one question, how do they know the logs were not already petrified and they were not moved in a petrified state along with the lava to end up there?
Good question. I would think that petrified wood would show the effects of that kind of extreme heat...? It should....
Stoked!
Shouldn't that be... Stoned! ;)
Always great to catch your lectures ... Do you have ice core sea sediment lecture ?
The warming of the polar region would go along with the pole flip/crustal displacement/axial shift theories that are becoming more common.
Nick should do a crossover episode/lecture with Hank Green in Montana. I think that's out where Hank lives.
Brilliant teaching Nick Z
Just curious.... have you ( Nick) heard of the expanding earth hypothesis? Wind could have blown Australia, china and Siberian sand into west coast. I know its hard to explain where the extra volume is coming from..... besides that. Can u make an un biased video on the pros and cons of the theory? It is important to hear opposing theories as well as the accepted theories.
Btw. Love your enthusiasm and geological expertise. I listen to your lectures all day while i work!!!! Thanks and keep em coming!!!
This was beautiful. For someone who loves studying the PETM in WA. I forgot my profile picture is of me by Canada studying the Palms at Chuckanut.
This was outstanding...
Gonna apply same to Deccan Traps here in India..really was quite a information..
Is there anyone lecturing about them/it aswell? If so please leave a link. This is so interesting.🙂
@@annaakesson2413 Aah here in India..people are just buzy with their jobs..posting such lectures is nearly impossible for us here..but whenever i find such i will link here.
Professor, I believe the trees were drowned by prehistoric lakes and water logged which would keep them preserved and on the bottom, the the ginkgo flow would've flowed towards the water cooling as it flowed into/on to the lake cooling on top of those logs!
