- CWU's Nick Zentner presents 'Plant Fossils in the Pacific Northwest' - the 25th talk in his ongoing Downtown Geology Lecture Series. Recorded at Morgan Auditorium on April 10, 2019 in Ellensburg, Washington, USA. www.nickzentner.com
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.
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?
Nick deserves an award for procuring those journals. That is outstanding! George deserves to have something named for him as well for donating those.
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 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.
@@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.
@@billwilson-es5yn Thank you
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.
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 love all these videos. Literally geek out on them every night. I’ve watch all the videos in the whole playlist now. Can’t wait to see what is next!
Second time through for me....lol
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.
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.
OMG OMG OMG!! Its here!! ..2nd Lecture!
I can listen to you talk all day. Learning so much from your lectures
Absolutely fascinating. I learn so much from each lecture...Wow..!!
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!!
Yay!!!! New Nick video!!!! Life is good. Thank you sir!
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 can’t get enough of your lectures. You are such an incredible teacher. Greetings from Belgium 💕
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.
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.
I was out gold hunting in Lancaster county and a man I ran into told me he’d found 2 ounces of gold in peters creek, conowingo cliffs area
I cannot get enough of these lectures!
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.
With all the knowledge from this video. This summer is going to be epic. Thank you sir.
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 UA-cam Land. Ciao, bella!
The brilliant Professor Zentner strikes again!
I come not only to learn about geology, but to learn how to lecture.
No kidding...i study Astrophysics and lol...our lectures aren't as " active " most of the time.
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.
@@crusindc5282 and have an awesome voice. 👍🏼
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.
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.
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.
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:)
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
Yep, he's something very, very special.
Amazing stuff. The hero is Nick Zentner for persisting in his pursuit of George Beck's journals and memorabilia.
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!
Another excellent presentation. Thanks from Australia 😀
Nick Zentner could just as well teach the art of public lecturing... which for the most part is a lost art. Bravo.
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.
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
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 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?
I came across these lectures quite by accident. Extremely interesting, even for a person in British Columbia. Looking forward to more.
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.
I've got to get out of Apache Junction and get back to Ellensburg _...I've _*_GOT_*_ to !!!_
AJ sucks, traffic to Renisaunce festival, Superstition treasure hunters, Gold Canyon old farts, where poppies once grew. Sad.
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.
Great to have your lectures back Nick!!
"..a bunch more moisture.." - Nick certainly has a way with words
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.
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.
Truly value your talks, Nick. Well done!
Seen the stuff he's been doing since COVID? Awesome!
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!
The moment I heard Hank Green's voice in the video from PBS Eons, it made my day. UA-cam is an amazing educational tool. DFTBA.
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.
I just love these! Thank you so much for sharing, I've been learning so much.
A great lecture. Thank you.
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!!!
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 .
Thank you for this engaging lecture!
I love watching these videos please keep them coming!!
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 ;)
Amazing, this turned out to be something other than I expected. I really enjoyed this lecture. Thank you.
ANYTHING from Nick, regardless of subject, is well worth watching!
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 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!
These lectures are fantastic!
*lets out a fangirl squeal because a new Geology video is up with my favorite Geologist*
I really REALLY wish my body would let me hike all over hell and breakfast... because I would NOT be doing the major I am doing now if I could. I've crawled all over much of the state of Idaho, and then my back said no more. :( I still try tho! I was given my Grandma's old walking stick so her strength and love of the outdoors will be with me. :)
Thank you for sharing. You bring the past to the present.
Wonderful!! Thank you so much- love your lectures!
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.
Keep them coming. You help me plan my off time and weekend trips.
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!
What a "ROCK SLUTH". This is a great story and a Geo Mystery. Great Job and another great production. Working your way up to Nat Geo,
Nick should do a crossover episode/lecture with Hank Green in Montana. I think that's out where Hank lives.
always interesting from Nick; looking forward to a global climate lecture
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.
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...
51* 04'51"N 121*37'45"W
Pumice maybe?
What a great lecturer on an interesting subject!
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.
The confusion people have between dinosaurs and the mammoth makes me think of the irritation experienced by archaeologists when people assume they are dinosaur hunters.
I have an archaeologist friend who has a Tee shirt emblazoned with large letters that say,
" I'm An Archaeologist.
NO! I don't do dinosaurs."
LOL The dumbing down of America.
@@mariashelly6392 There has been a sort of malignant dumbing down in America, but my archaeologist friend with the Tee shirt is English, as are the people it is intended for.
There was a flat earth conference here in Canada and one in the UK.
Being a member of an intelligent species does not necessarily indicate intelligence in the individual member of that species.
Stoked!
Shouldn't that be... Stoned! ;)
Good job Nick. I put it out on my FB.
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!
Inspiring, thank you Nick!
Great lecture, thanks!
Yay Mr Nick is back!!!
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!!!
Another great video. Thanks for posting.
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.
I put a nice layer of grass under the T.Rex fossil 3d print on the diorama landscape... then found out grass evolved later! DOH!!!!!
As a botanist I can tell you that this is not true, just leave the grass under your T. rex. Look at the "Poaceae" page of Wikipedia for some information.
@@eudyptes5046 thanks I will do more research on that Poaceae. For an amautur fan of geology and paleontology just knowing the word for the 'thing' is sometimes a research project in itself.
There's a spot right inside the town of Republic where you can dig for plant fossils.
What a happy ending. I wonder what wonderful insights have been lost when someone just threw away those old journals of some long gone geologist?
ARGJ! Dont even THINK that!
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.
The warming of the polar region would go along with the pole flip/crustal displacement/axial shift theories that are becoming more common.
This was outstanding...
PLEASE do a global climate lecture!!!!
It would be wonderful if you uploaded those records on UA-cam...sounds intensely interesting
This guy is a gifted communicator.
I wonder if the PETM rise 56ma was a mass methane release. I’m thinking of the things that can cause global or even regional climate change and methane is the first thing that comes to mind.
A volcanIc eruption? Plasma event?
Actually folks do think it was a methane release, it is the leading hypothesis! Methane gets trapped in the deep ocean and builds up over time. The methane comes from little micro organisms that eat way at organic matter on the ocean floor. They release methane, but methane does not like water (it's hydrophobic), so it just gets trapped down there. But if there is some kind of initial warming, the oceans warm, and gas moves through the water much easier. So the methane escapes in huge quantities. That's why they think the warming was so sudden and drastic. But even before and after the PETM happened, climates were still really warm compared to today. They cooled somewhat gradually from then until now. And that is a whole other story that is heavily debated, and might have something to do with generally less volcanic eruptuions
I noticed something in the black palm (your office area) has blunt tips - I suspect chewed off as it is the softest part. Not by a Dino, but by a muncher with a long nose to breath while it ate under and in swamps. Martin ps The magnetic north pole wondered all over the 'pacific' before returning to the north. It depends on the ice load and land load and distribution on the globe of the land masses. The Earth is a magnetic 3-D bar magnet something shaped like a pumpkin with ribs and dives into the poles (the magnetic lines). BUT the great ocean into the Montana from Texas might be effective. I have to look up some of my notes (50+ years to college days) and find those dates. You know, Reef structures (coral) at the top of the mountains in Colorado.....
Nick is GREAT!
I thought some of those circles in the Basalt were found to be fossilized plankton? My Professor at Southeast Missouri State University doesn't know what she's teaching about. I wish I had you as my teacher, I learn more from watching these online lectures than I learn in class. She actually told our class to watch your online lectures and your weekend online blogs.
Wise lady.
YES, another video
Always great to catch your lectures ... Do you have ice core sea sediment lecture ?
