All thanks to you...again...as we enjoy your wonderful videos. ❤️
The earth opened up, and she belched out lava for hundreds of miles, hundreds of feet thick. Mind blown!
Nice tree stump.
The columns are the way thick layers of basalt lava cool. They are like the columns on Devils Tower. It's called columnar basalt, and absolutely breathtaking in person. To imagine the layers of lava flowing though the land is amazing.
Beautiful lesson on these structures. And we talk about global warming, it must have been pretty darn hot around WA then!
Thanks again to you guys, Pete form the Isle of Wight.
Ah, it's this kind of stuff that makes me wonder if I've chosen the right career sometimes (biology) but then again, there's just so much wonderful stuff to learn everywhere! A dozen lifetimes is not enough, and we're naught but mayflies with our one day. Ah well, learn what you can and enjoy your moment. There are wonders everywhere.
55 years of driving along I-84 and not appreciating what I was seeing. I wish I had known half of what I know now.
Brand new to me! Thanks.
Yeah, I'd really like to learn more about the chemistry and physics of those other sites as well. I simply cannot imagine the amount of heat that was released by those events. And creationists all think it happened during the Noachian Flood. Un-effing believable.
Excellent piece of work. I would've liked to see more data on the physics and chemistry of the flows and how they impacted the environment, but I'm still very impressed. Can you recommend some more reading and resources?
Have you heard of the lovejoy basalts of northern California? I read a paper that said they were related to the Columbia river basalts.
Very cool. I wondered how the rock around the waterfalls in the gorge got those strange columnar patterns
It's a natural hexagonal pattern that forms in flood basalts as they cool. They only form if conditions are right though and often times these columns are much less uniform in shape, size, and texture.

Here's a great example of three very differently formed basalt layers that are stacked on top of eachother.
Another hypothesis that has been put forth regarding the formation of the Columbia Gorge and the Columnar Basalt groups is via electrical discharge on a scale unseen today. The Grand Canyon also has been hypothesized to have been created this way in a very short period of time. There is evidence to support these hypotheses.
except for for all the melted silica that would be present from the electrical event, this even and grand canyon have already been explained with evidence.
It's an interesting hypothesis but from what I've researched has very little evidence to support it.
I have some trouble looking at these images and separating what are different flows stacked upon one another from horizontal fracture lines in the same flow. Or is it that these horizontal factures are all occurring between flows. See (0:42), (1:12), (4:07), etc. And if younger flows are stacked on top of older ones, why is there not a filling in of the gaps below. It is somehow hard to picture, but I get a sense of years of erosion, burial, lava flows, upheaval, erosion, burial, lava flows, upheaval...along with the flooding, columnar falling away, undercutting of the Entablature, Entablature falling away, rinse&repeat... idk it would be nice to see a diagram/animation showing how we get to the top of a mountain stacking multiple flows over time resulting in this terraced appearance with a large old base and smaller remnants of younger flows on top (4:07). It just seems counterintuitive that the older flows should stick around longer. And I've got questions about the Entablatures...is there aways an entablature... so where we see the tops of the columnar... the Entablature has all eroded away. Do we have flow ontop of flow were there is Entablature/Columnar/Entablature/Columnar... is that what we are seeing at (7:20). At one point, the Entablature is mentioned as a protective cap, but it is weaker than the Columnar isn't it (Dense in the number of cracks). In the Drumheller Channels mesa (7:26) I would think that the polygonal edges in the Columnar well rounded, or would the floodwaters just have pulled down columns until it subsided leaving whatever was left standing behind still well shaped. Note the line of weaker looking rock midway up the mesa (7:26)... is that a water line? Or something more like what we see in (8:55) that looks like compression & twisting of the rock... as it formed & cooled? So many thoughts and questions this brings to mind. My apologies for being so long in the post.
I feel cheated. No Nick!
EL ANO PASADO FUI DE VACACIONES A TRI CITIES, Y RECORRI EL CAMINO HACIA PORLAND Y OBSERVE CASI NOMAS ESTE PAISAJE DE LAS ROCAS BASALTICAS SOBRE EL RIO COLUMBIA, UN PAISAJE PARA MI DIFERENTE EN EL CUAL CONSERVO VARIOS FOTOGRAFIAS QUE TOME EL ANO PASADO
Это впечатляет, конечно! Ах если бы еще был перевод на наш язык...
So all these events are part of the hot spot travelling up to and beyond the Snake River and into the current Yellowstone supervolcano magma spot. This is what all the upwelling lava basalt came from in times past?
John Lord That is one of the 5 current competing claims of magma- origins as a "volcano".
Not an expert on this particular point, but it could be the remnants of the subducted Farallon Plate being brought back to the surface by vulcanism.
@@NorthForkFisherman There are comments that this is a sub-sliding (not subduction) Resurrection Plate or Kula Plate, all before Farallon-Juan de Fuca plate was in the area. And as plate tectonics, it busted up against the deeper and stronger North American craton, ... along with a seafloor spreading ridge that can still be seen under the Pacific Northwest, ... these events caused "interesting times" in the Eocene to Miocene period.
@@johnlord8337 I certainly know about that here in Kansas. Ashfall Fossil Beds is not that far away. A rather grim reminder of what "interesting" means in geological terms.
@@NorthForkFisherman do you have any gingko fossils there? Dawn Redwoods? and how close to the Grenville formation ? Part of the AUS-US connection during Rodinia and Pangaea and giving us gingko trees 200 - ~150 MYA. Grenville formation provides the best Rodinia and Pangae model and how we formed up and then broke up.
So you're thinking that there might also be a chain of batholiths running under continental crusts arising from hot spots as well. That's interesting. You know, that might also indicate good places to mine for rare earths - alongside these upwillings? And the zircons could also show if there were changes in speed or direction of drift. Hmmmm. Interesting ideas.That's what I love abbout YT sometimes - you run into people who make you think.
Funny watching this felt like singing the karaoke..
Actually that's not quite so - the earth was never reduced back to prokaryotes and wouldn't be unless we had an event similar to the Late Heavy Bombardment. We did lose about 95% of known multicellular species and so what remained had to expand into those newly opened niches. And being a rock and volcano guy is a very good thing - that's were current studies show life most likely arose first - hot springs fed by geothermal energy and chemistry.
Yes I've often heard it said that biology and geology are simply subbranches of chemistry, which in turn is a subbranch of physics, which is finally a derivation of mathematics. Whew - Everything is interrelated. And yes, given what's known about carbon chemistry, you're probably right - if life exists elsewhere (90+% IMHO) it will be prokaryotes tied to a chemical/thermal source. Just the nature of life - manipulating whatever free energy is available in the system.
Thank god we r idiot keep up the good work
All of the people who think Devils tower is a tree stump need to watch this video.

Logically my mind finds this science hard to see ..
So much to figure how pyramids blocks was made ,cut and carry? And of course will need alot less humans and alot less cutting and if constructed using the same formation maybee thats why no one ever see where all those rocks come from cut like that. Probably the formation was exactly there ,this things are huge octagons some huge squares, some are round.I problably will be the first and only one who think or guess about this idea (lol) , i see one of the Pyramids that it's falling appart and looks just like in this video.
Except that we know where the blocks of limestone and granite used for the pyramids were quarried. Neither of which form these hexagonal columns by the way; so you're wrong on both accounts.
Only if there are enough resilient generalist organism populations around to repopulate and speciate out. And I think you're talking about telomerase? We can manipulate DNA to create pretty much any pattern we want - the big thing is knowing how to switch on and off the genes and promoters in the right pattern to create the outcome we want. With the human genome project we were able to transcribe every base pair found - too bad the book it provides is written in a language we cant read yet.
Lava.....bullshit
@@johnbiggins4864 (slow clap)
Over seven years later. And the utter brilliance of the two words..../s
I'm calling bull shit on this one.
its obviously biologie ..
Not lava! hahaha!!!

Lava flows ? Hundred years to set then another hundred years to cool makes no sense.
it pours out for a long time and is so thick it take years for it to solidify into Columbs.
None of these basalts look like tree stumps. How did anyone come up with the idea that flood basalts were tree stumps?
Look at a plant under a microscope and u will see hexagonal tubular shapes just like the basalt tubes.
@@lifeisa.smalllesson4607 Hexagonal shapes occurr all over the planet. These are flood basalts, dear. They're formed by lava.
@@fructosecornsyrup5759 I was explaining where the theory came from....which is what u asked, dear. Not stating my beliefs
very good video but what amazes me is that there will always be a few thumbs down---i think its computer generated. also i would like more information on the fissures locations--i have always read they cannot even be guessed at.
