CWU's Nick Zentner presents 'Wenatchee Ice Age Floods' - the 10th talk in his ongoing Downtown Geology Lecture Series. Recorded at Hal Holmes Center on June 5, 2013 in Ellensburg, Washington, USA. www.nickzentner.com
I didn’t even know I liked geology until I stumbled across one of Nick’s videos. Now I am addicted. Captivating speaker and makes the amazing geology of Washington come alive.
Similar story for me, except i have always wanted to study geology, but was put off due to much of it having a huge snooze factor. I think i must somehow be part raven: ya gotta show me something shiny to help hold my attention or, next thing you know, i’m flapping off in search of shinier objects. Nick Zentner has HANDFULS of the shiny stuff and, lo and behold: i am a good student! Thanks, Nick!
An excellent presentation. Your organizational and presentation skills make your lecture fascinating. I believe if I had been fortunate enough to take a geology class from you (impossible since I am 76) I would have elected a degree in geology, not the path I finally chose which was a degree in mathematics. I watch every one of your presentations I can find. Thank you for sharing your knowledge with us and inspiring an old guy to continue his studies. It is wonderful to be able to awake each day and look forward to learning something new, to gain insight to something one has wondered about. This is the most exciting time in my life. Thank you Dr. Zentnerr.
I am an electrical engineer; however, I love history in multiple fashions, and I can not help but watch your lectures. I found the Basalt lava flows and the Cascadia fault slips very interesting. That is one of the few areas of the lower 48 that I have not yet experienced. I wish my instructors had the passion and due diligence that you have for your lectures.
I've been out Tacome 4 times. My daughter lives there. The view of rainier is breath taking. Get out there, it is a sght to see. And the lectures are very informative.
I have always been fascinated with the floods that shaped eastern Washington since a trip through the area when I was a kid. Found one of Nick Zentner's lectures on the subject a few days ago and now I cannot stop until I have seen them all. Great presentation. Nick's students are so lucky to have him as an educator.
The complexities of this planet are fascinating. The most active force seems to be water, in its various forms. Enjoying these lectures. Carry on. Peace, love, and aloha y'all.
Holy crap on a cannoli Doc! WOW! You've shown/explained/ defined the area practically perfect! This expands Lake Missoula Floods so much! And I absolutely LOVE your K.I.S.S. talks. Keep up the great work! I'm going to recommend these talks to University of Idaho Geography and Geology Departments
What blows my mind is my experience with flooded streams in my youth. All the same features seen then, ripples, flood bars, ice deposited debris along stream edges, etc. , but seen here on an unfathomable scale.
I recently stumbled onto your lectures. I am thoroughly enjoying them and I have learned so much by watching. I have been to Fort Lewis once and my wife and I have returned to see more of this beautiful state. Thank you for making these and allowing my wife and I to watch them.
Fascinating talk! But also a blast from my wild young days at CWU. My ex was friends with Bill Pratter and also Barry Prather. He also knew Bill Long, who he convinced to guide a field trip up one of the glacial morraines at the edge of Leavenworth. That trip was an amazing and magical day for me. I so enjoy your videos. I'm part way through the Geo 101 series, which I intend to finish. Currently I am at week f of your eocene series. I am pushing to try to catch up but busy trying to read all those papers. I have traveled around Washington and the west since moving here in 1962 from VA. My mother was curious about the geology here but info was hard to get then. I flunked Geo 101 at central in '68. I went on to take a lot of Geography at CWU. My major was Cultural Anthropology and duel with Education. I live in E Wenatchee at the bottom of all that flood water. You are filling my cancer treatment months with answers about places I have known just a little bit about for many years. Thank you for getting me more excited about rocks.
The world needs Nick to be the first CRISPR clone! I grew up in North Alabama, Georgia, and Eastern Tennessee. I'd watch Hillbilly Nick. I live in SoCal now so I'd watch Nick Dude too. I never imagined I'd watch hours of educational info about Washington state. I've been as close as Spokane in my late teens. I didn't think much of it then. Now, after watching a bunch of this stuff, in my mid 30's, I must have been blind :-)
Another awesome lecture Nick. As a California geologist I am well versed in the geology of the Cascade volcanoes and vaguely the Columbia Flood basalts. Now you’ve got me hooked on exploring the Ice Age floods.
Google his name. He is very active on his own personal channel now. still works for them, but during the pandemic he's been taking the time to do his own personal content basically daily.
I poled my way up the Wenatchee River on an iceberg --- I used a really long pole. Yes, I remember it as if it were a mere15,000 years ago. I wanna tell ya, I was cold by the time I got where I was going!
I have a question for Nick. He talks about these blue agates from Ellensburg, but one time while walking a Logging Road I found a fist-sized rock ( I have a large fist) with approximately a quarter of It calved Away by a Caterpillar Track. I picked the rock up amazed that the caterpillar was able to break it in such a manner, and then was distracted by events of the moment. I pocketed The Rock fragment and discovered it in my jacket at laundry day that week. By that time much of the dirt head rubbed away from the stone and it became evident that it was a translucent blue! I washed the stone out of further curiosity, and sure enough it was a bluish green agate. The fragment also has a vein running through it of a brilliant red color like Ruby! On close observation you can see that the vein is not entirely solid but is still actually a tiny venule. I only wish I could grab the rest of the Stone from the Logging Road. The exceptionally curious part is that this Stone was found nearly to the Olympics in Central Western Washington? While I realize loggers bring in gravel for their roads, I also realize it would be terribly costly and inefficient to truck it all the way to this point from Ellensburg...? This leads me back to the initial question. How would this Ellensburg blue Agate have made it onto a Logging Road nearly to the Olympic mountain range, with only the Hood Canal remaining in between? Is it possible that the phenomenon that creates these agates was not exclusive to the West Ellensburg area?? If my ex has not lost the stone it would be something I would like you to see! I could then give you further information about the location where I found it.
I'm living in Oregon (from Bloomington) for the next several months. I would love to attend one of your lectures.. you're a good 4 hour drive from Mt Hood area here.
There are numerous stuffed suit college professors that have lectures online that are completely unwatchable.. Not this guy. Great lecturer.. His use of old school chalk board is good too.
Movement of Ice Age flood water up the Columbia River from the confluence of the Spokane River? Or was Lake Columbia water so deep the flood water had little effect? And, where is the edge of the Columbia Basalt in this area? and what effect did the faulted basalt have on the flood water flow? Nick, your lectures are fabulous!
+Alison Addicks Thanks for watching, Alison. I'm just starting to think seriously about Glacial Lake Columbia. See my recent Bing Crosby & the Sunset Highway lecture. The edge of the basalts is in that area also. Faults not significant for IAF, but the ridges made by the faults controlled some flood paths.
I live north of Wenatchee, up the Entiat River Valley. Very interested in your series. My youngest son graduated w/ a degree in geology from CWU.. I've asked him on my fb page if he knows you and if he knows where the gneiss is from.
If the flood flow equaled the combined sum of all the worlds rivers when Lake Missoula emptied - What was the potential rise in the Pacific ocean? Or was it insignificant given the sheer volume of the Pacific at that time? It would seem that such a figure could be quantified with the modeling software available to hydrologists who have worked on this. (Just wondering)
The math is pretty easy: the entire lake Missoula is reckoned to be in the range of 2100 to 2500 cubic kilometers. The volume of the current world oceans is about 360 million square kilometers. If we divide 2500 cubic km by 360,000,000 sq km, we get about 7 millimeters of sea level rise. The Pacific is about half of that area (181 million sq km), so its level would've risen 14 mm ... half an inch ... before the excess redistributed itself around the planet. Messing up the "easy" math is that the oceans were about 130 meters lower during the ice age, since they contributed most of the water that went into the ice sheets. Balancing against that "makes it bigger" effect is that the entire lake didn't drain during each of the floods... so the 14mm is probably a great over-estimate.
Thank you for your reply. About the Lake Missoula Where do you get the information that alludes to the entire lake not draining? Given the height of the lake and the force of the flow once it began, it would appear that it would come very close to emptying if not completely. If not there would be some kind of lake in that basin now. From what I can tell there is only the Great Salt Lake which is a rem anent of Lake Bonneville.
I should have written "the entire lake *probably* didn't drain"..., since i have no idea if it did or didn't (that would depend upon the depth of the (also scoured) floor under the "dam" and whatever ridges and valleys existed enroute compared to the depths of the areas covered by the lake). My calculation was purely aimed at estimating sea-level rise, and therefore used the "complete lake drainage" volume estimate. Reality and back-of-envelope calculations frequently differ.
At the 39 minute mark, those lines are cooked red brick lines. Tartarians used red brick, mortar and much concrete in their arc-hi-tec-ture. The Tartarian Empire was a free energy society and of course, even had plumbing for water. Red bricks store energy, so, in order to have free energy everywhere, red brick buildings had to be in all construction.
Still being studied. The causes of Ice Ages are still a bit of a mystery. Most attention has been focused on Earth-Sun relations....and old positions of continents and ocean basins.
I think it's likely that there isn't one particular reason, but various mechanisms. A study was just published that gives compelling evidence that the onset of the Younger Dryas was due to impact/impacts or airbursts from a large comet or pieces of it after it broke apart. I'm leaning toward Schoch's theory that a CME brought the planet OUT of the Younger Dryas. The evidence is accumulating that we have rendezvous with cosmic objects much more frequently than was previously understood, and if confirmed, provides an energy source more than capable of sending the earth into ice ages.
When people (so-called professors) try to tell me what happened BILLIONS of years ago with such audacity, I think to myself .... I'll take the Wood-Working class.
What do the native Americans say of the Ice Age Floods in their oral traditions? They would have found 1000 ft high flood waters moving at 60 mph a very dangerous and terrifying event and would have attributed it to something.
There was 1,000 feet of water for hundreds of miles in Northern United States at one point. ONLY a comet, impact, or multiple comet impacts, could melt that much water and create that many floods on that scale. There isn't just flood scarring on a massive never before seen scale in only a few areas, you can literally see the water erosion on a MASSIVE scale all the way from Northern USA down to the Grand Canyon and West Coast, down to the Gulf of Mexico, and even into the East Coast. And we are talking about the floods from 14,000 years ago, there are 2 HUGE flood spikes which perfectly match 2 animal extinction spikes. If you placed the Great Pyramids of Giza in the path of one of these floods, it would turn into a pile of rounded out boulders with the exception of the few MASSIVE granite pieces on the inside. That is how powerful a flood is, when it is from a 2-3 mile thick ice sheet being impacted by just one comet, this was multiple comets/meteors. (the Great Pyramids were built long before the Egyptians arrived there, not by the Egyptians, proven by the reshaping of the Sphinx's head alone.) Noah's Flood, The Great Flood, etc etc etc all peoples and cultures have their own version of the flood based on where their ancestors were and where they came from and where they were.
But what caused the Ice Age flood? That question was avoided in this lecture for good reason. While I respect Nick immensely, he doesn't want to rock the geological studies boat by suggesting that something massive hit Northern Canada to cause the immense flooding that he describes here.
Great info, I'd like to add this however. . 12 to 40 or so whatever tainted inaccurate radio carbon datimed... years ago, is more like 6 to 7 thousand years ago. Jesus Christ is king. 👍🐑
Ohh don't forget, conventional oil is renewable from decomposing matter in and on the earth. You were taught it's from dead dinosaurs🐑🤦. Yes it's all Rockefeller propaganda science.
Chalk boards add charm + Nick does a better job explaining things using chalk boards than other presenters do with more modern gizmos. Keep up your awesome work Nick!
This fellow who is using peer review science, completely contradicts Randall Carlson's hypothesis that 1 giant comet caused the flood that carved the scablands. Notice Carlson never mentions the huge number of rythamites found in these areas where the flood waters backed up. Why? Because if you have solid evidence for a crap load of smaller catastrophic floods (each rythamite is evidence of a giant flood and they are carbon dated) rather than just one massive one, then Carlson's hypothesis kind of falls apart.
@@Quixote1818 I feel you should look at Carlson again...he does not contradict anything Zetner teaches except how ice dams may or may not be able to hold back such huge quantities of water, and he has an excellent lecture on that. Has anyone out there found someone who has proven absolutely that ice dams could hold back the glacial lake in Montana? And we will find the evidence for a scattering of the comet event that caused the YD event...I agree with the theory of the suddenness of it but it seems that looking for a single crater won't explain the whole thing; that the earth was hit with several atmospheric 'bombs' over the continents.
@@Quixote1818 27:03 - Missoula Flood layers. [ Nick Zentner ]. 39:50s - more than 90 separate Ice Age flood events. [ Nick Zentner ]. Both sites, both sets of layering, from exactly the same sequence of 91, or 93, Missoula Floods. What accounts for such a reoccurring sequence ? An ice dam would build up then break, time and again.
