I saw a PBS show on the Ice Age floods a while ago. In 2013 my wife and I took two months vacation to explore the floods from Missoula to Astoria. I also met David Alt who's book I used for a guide. I'm glad that they are finding out more about the timeline. This was well presented.
Well done video and Nick Zentner has a natural talent for engaging the audience and conveying complex concepts in bite sized easily consumed scientific information. His skills with the chalkboard are also amazing. Great work Nick and a shout out to the supporting team as well.
This was really good. But I would also like to see some stuff on the Ice Age Floods near the Great Lakes, like the Kankakee Torrent. The Pacific Northwest events get all the love.
I've always wondered how dating worked during the ice age. I didn't know we knew enough about the subject for 90 minutes, but hey, I'm down to learn how to pick up some Pleistocene babes.
Could the thickness of the slack water sediment layers get thinner as they are laid down because of the water course running in the same pathways and having less loose soil to pick up and move downstream? If you hose a concrete driveway off that is covered in dirt and gravel, the first time you clean it you get the most debris. Subsequent washings will result in less debris each time you clean.
Thank you Nick! you're a geology rockstar. Most shy away from topics that are yet to be fully explained.. you show us the newest evidence and highlight the areas we are not positive about. I loved your segments on drumlins. There is a huge story here that is only beginning to unfold. It is an exciting time to be interested in such things.
That flood sequencing makes more sense. I've been watching lava and that's how it flows, er, floods. 😉 As always very interesting and enjoyable presentation. 👍
If they also tested the age of the quartz from inside the same boulders, and the inner quartz returned an age of zero, that would be far more convincing. Instead we are left wondering if there were any “daughter” elements in the quartz when it was formed.
Well.. PBS ran a special on earliest footprints discovered in New Mexico at the White Sand National Monument a few weeks ago. They were dated between 21 and 23 thousand years ago. If the bearing straight migration theory is valid you can be certain people lived in Washington state before they got to New Mexico. Even if you believe the people came form South America I think it's pretty safe to assume they would make it from New Mexico to Washington State in 6 to 8 thousand years to witness the floods.
Well... civilization didn't just spring up overnight. It took tens of thousands of years of developing the skills necessary to achieve it. Passing information from one generation to the next is chief among them. Almost every culture on the planet has ancient tales of giant floods.
@@rabidbigdog While the chances of actually finding a wooden structure from 10,000 years ago is virtually nil, it is not unreasonable to assume that such a thing was constructed in some form. In fact, it would be quite reasonable to assume that more than one was built, successfully or otherwise. After all, the Bible is not the only source of a story like Noah's. It is one of several.
Interesting lectures, I've enjoyed listening to them and learning something about how this planet has evolved.... Now, can they be retold at the "Creationist" point of history???
Thank You Nick. I wonder if the floods coming out of the Okanogan lobe were giant glacial outburst floods. Moses Coulee looks like it is situated near the terminus of the ice sheet. Any evidence to support this claim?
I have always liked geology at a ground level education. but being in NW Ohio and finding a fist sized lava bomb. only adds to the questions what Volcano blew chunks that ended in Ohio?
I would prefer have a date with a nice person or even one of my kids or siblings. Dad was a great date for supper. Mother was a great date for a good movie or church. We were never late. But dating ice in any age sounds like a boring date choice.
You're just being sexist! If the Floods were younger than Nick, you wouldn't be saying that... You'd be saying, "Holy shit...Nick looks good for being more than 15,000 years old!"
@@badgerpa9 A. Funny or not, it was a joke, not a comment intended for dissection or serious discussion. B. If people think it's OK for a older *man* to date a younger *woman*...but not for an older woman to be with a younger man. The discrimination there is over the sex of the older person vs the younger one...not the relative ages of either.
@@badgerpa9 Wasn't mad, just didn't know if you had suddenly gone all serious and literal. Since I was playing off the way society still treats the sexes differently, I still don't see this as ageism, but I understand why you do.
Haha!! When I first glanced at RU-vid I thought…What?? Dating an Ice Age? How does that work?? Obviously you don’t take an ice age on a date to a hot spa day😅😅😅 Maybe an ice skating date? Well Nick this would be an interesting class….. just saying….
The rhythmites can be explained. We know that the Wallula Gap was the bottleneck. We know that large ice masses escaped through Wallula Gap carrying huge erratics. But they didn't pass through the Gap simultaneously. From time to time the Gap was largely plugged, which slowed the velocity of Lake Lewis drainage and allowed Slackwater sediment deposition. When the ice plugs shifted, the drainage increased, which allowed other ice masses to fill the holes again. And again. And again. Each time the Wallula Gap ice plug re-established itself, a new rhythmite was laid down. It was not a "new" flood emanating from the glacial lakes; instead it was the Wallula Gap ice dam reorganizing itself as it tried to pass through the bottleneck.
I'm just here to say that I thought this video was gonna be about dating (as in, "going out with") literal floods. Just goes to show how ridiculous RU-vid titles have gotten, that I expect someone just dating water for content
In the beginning was the Word, and the Word was with God, and the Word was God. 2He was with God in the beginning. 3Through him all things were made; without him nothing was made that has been made. (John 1:1-3)
The one thing they never talk about is when the Ice Age actually started ? They all try to predict when it ended. The sun is on a 12,068 yr NOVA cycle and the Pole shifts on an cycle also, but when they both happen at the same time then that is when everything changes due to Gamma Rays, Cosmic and Ultra Violet Radiation, including Evolution, on planet earth.
What came first the continental glaciers with lower sea levels or the cataclysmic East to West tidal waves that get pulled around the planet every 40 years at the conjunction of the plants for the 1,000 years it takes our solar system to eclipse our galaxies double torus electromagnetic gravitational plane?
I see no way a dam made of ice could hold back that much water. I believe Randall Carlson's study that the ice dam is an impossibility with that much water behind it.
Think of it more like a frozen permafrost bank of the lake missoula that gave way under the pressure due to possibly an earthquake or an uptick in solar activity
@@poorpauly1308 A constructed concrete dam couldn't hold back that much water. Ice did? I laugh. Peer reviewed? By the same fools who believe in the ice dam fairy tale?? LMAO.
@@jimmysliver2581 You really should get an education, because you are 100% wrong. Too bad for you the evidence for that very fact exists and is not disputed by real science. Now, try using some real science and stop following quacks who do not do any science.
@@TheDanEdwards you do know that since 2014 the golf of Mexico has cooled almost 5 degrees at 60 feet and so has the north Atlantic! The oceans heat the atmosphere!
@Seth Stein ok doesn't the golf stream heat the Mediterranean Sea, the British islands, the Nordic countries, Iceland, green land and the Atlantic provinces? And aren't they all cooling because the Golf stream is slowing? Dose not the pineapple express heat, Washington, BC, Alaska, and the Russian coast? And aren't they all cooling because it is slowing? ,d we do know that the warn Editorial oceans are what drives all of the Ocean currents?
@Seth Stein sum bright sunny day put a bell jar full of air on a glass plate 4 feet off of the ground for a few hours and see how much cooler the air in the jar is then the air outside it! No the sun heats objects not the air! And fill the jar with Co2 and see how much cooler the ground in its shade is in a few hours! Grade 9 physics 1970!
Not mysterious Nick....called the Genesis Flood....Of course Montana and the Clark Fork had to be the water source? Not a chance, you guys bought into Bretz theory of the water source and haven't turned over a rock since. You guys bought into no chance of a bigger event. Bonneville, Grand Canyon, Missoula, etc etc around the world were one event. If it happened thousands and thousands of years ago the ripples at Crescent Bar and Camas Prairie would be long gone from erosion. Genesis Flood.
_"and haven't turned over a rock since"_ Why don't you look into the papers that have been published about the Missoula flood? They are based on a lot of turning over rocks and collecting data. The only ones who are not collecting data are the clowns from Answers in Genesis or the Dishonesty Institute. They stand in front of cameras and fundamentalist crowds, telling neat fairy tales in which evidence is replaced by handwaving. Unfortunately they have no model, they have no calculations, they have no peer-reviewed papers, they have nothing. They only have the paychecks of people who are believing in a book from the late bronze age and who therefore are handing out money for being told what they want to hear.
WE HAVE THE GENEOLOGY FROM THE VERY FIRST MAN AND WOMAN BUILT, ALL OF THE WAY UP TIL 2000 YEARS AGO - AND THUS WE HAVE THE GENEOLOGY GOING ALL OF THE WAY BACK TO THE POLE REVERSAL EVENTS CAUSED BY ATLANTIS, AND THEN BABEL , ( WHEN THE EARTH REPOPULATED FROM THE FLOOD THAT SUNK ATLANTIS).. The pole reversal/magnetic fields and pressure reset event that babel caused, caused the mud floods, sea level rise, continent split, and the big ice age . About 4000 years ago.
