Spoiled for Oregon content recently! Possible anyone knows of other channels that focus more on the Oregon area to know about? Akin to what Nick does for Washington?
I very much like the longer format. In the future, if you have a topic that warrants a longer treatment like this, I'm all for it. That NW-younging volcanic trend really isn't well understood as far as I can tell. There doesn't seem to be a simple explanation, like changing slab geometry. ... I wonder if it isn't some interaction between clockwise rotation in the PNW and the YHS.
Given its position in eastern Oregon I can't help but wonder if it has something to do with the ridge like upper mantle low sheer velocity zone seen in seismic tomography imaging of the western US which goes under North America as a continuous structure joining the Juan de Fuca Ridge to the East pacific Rise which it also underlies. A similar structure of higher temperature upwelling has been observed for other major ocean ridge systems such as the Mid Atlantic Ridge but no other ridge on Earth can match the rate of sea floor spreading of the East Pacific Rise. This thermal anomaly beneath North America is also such a close fit for the regions of unusual "inter-plate" active volcanism within the Basin and Range and Colorado plateau. The only exceptions are the volcanism to the east of the Sierras and to the west of the Colorado plateau which happen to be along the edge of very distinct region of crust which is rotating like a rigid body rather than deforming differentially like the rest of the western US. The clockwise rotation of the pacific Northwest and Basin and Range is almost certainly related since all the rotated regions are either along the Cascadia subduction zone or lies to the west of the thermal discontinuity boundary which is otherwise a perfect fit to the East Pacific Rise and Juan de Fuca plate. And if you account for the compression ongoing within the cascades the rotation also maps to the relative motion between the Pacific and North American plates. This to me suggests that the real plate boundary, following the newer emerging deeper plate tectonic paradigm suggested in some of the papers linked to Nick Zentner's crazy Eocene & Baja BC A to Z series is actually along the snake river plain and eastern edge of the Colorado plateau and the part of the North American continental crust raft which has crossed this divide is now being torn in the opposing direction by the underlying opposing mantle flow. I don't really get why this update to plate tectonics is so controversial the evidence is remarkably strong with volcanic and igneous dating and petrology, paleomagnetic data and seismic tomography analyses all pointing independently to the same picture tracing North America's journey west accreting and then overriding mature volcanic archipelagos and then encountering the East Pacific Rise starting soon after around 50 Ma via a very jagged zig zagging juncture which has laterally locked the two regions via the continental root of North America to the north and east of the boundary. The only real problem it has is the lack of a well defined fault of translation but given that the modern Basin and Range isn't deforming along a single fault why should we assume such a well defined fault exists? Whoops this got a bit longer than I intended.
@@ThatOpalGuy I live in The UK but I still find this very interesting. I cannot see myself travelling this far, but the diagrams and photographs of similar eruptions help me to see the area at that time. What does the area look like now?
It's been a while since I last visited Central Oregon (I live in Portland which has an extinct volcano - Mt. Tabor - within the city limits), but my recollection is MILES of rough black rocks, many with patches of grey lichen, and occasional small clusters of trees.
This well deserved a longer report. Thanks for that. I had no idea this much volcanic activity has taken place in that area in addition to the actual Cascades.
This series of Oregon Volcanic geography is the Best. I driven eastern Oregon and Washington alot and always love the landscape. I had a geology Professor in College, he did his masters on the Basalt fields in Washington got my interests in geology.
always interesting, and the time just flies by ;-) Oregon has one of the most diverse landscapes and geology in the continental USA, deset to ocean, and everything in between...
I love your videos. You have plenty of science but we don't need a PHD to understand it. I love learning. I'm 65, grew up with NASA in it's infancy & got to take my mom's small portable TV to school whenever there was a launch so my classmates & i didn't miss the launch ! And geology is also a passion of mine. There's a professor, Nick Zentner, from Washington State who puts out videos that i watch time & time again. It's because like you, he talks WITH us & not DOWN TO us. Thank-you for the excellent work you do. 🫡 🇺🇸
Thanks! I really like the description of Diamond Crater's eruptive activity; it was very versatile! The caldera formation at the end is fascinating. It probably looked like the caldera collapse at Kilauea a few years ago.
Oregon= geologists’ paradise. I was astonished at the volcanic features here when I first arrived back in the early 90s. We spend time in SE Oregon every year and been lucky to have visited Diamond Craters several times. It’s an exceptionally impressive site in a landscape of astonishing geological transparency. Here’s hoping the trend continues and we get a Steens Mountain episode! A great chance to talk flood basalts.
As a resident of the PNW it's always great to get a bit more info about our various but not as 'famous' volcanic features. And I love the extended videos, too! Always nice to have a bit more depth and I really enjoy listening to your narration. You have a very soothing voice!
Another rare little eruptive series in Diamond. If I've learned anything with this channel it's that while there are have been a ton of one time or repeat volcanic eruptions of various types along the Cascadia Arc throughout history, chances of being alive to see any one in particular are extremely remote. That Mt St Helens took place in my lifetime was a rare fluke. And here I was hoping I might see nearby to me Mt. Baker or Garibaldi pop a little in my lifetime but good luck on that.
I do enjoy the extended length of video! Diamond Craters is an interesting area to visit as is the Steens Mt and Alvord. desert near by. Thankyou GH!!!
This one was amazing. Looking on Google Earth, I always wondered why there were lavas all around east of the Cascades in Oregon. Please continue talking about the lavas and volcanoes on the region.
I lived in Central Oregon, Bend, as a child and my mother often droves around to these places. I've been thinking of asking for just this video. I guess I'm too late now. thank you.
Hi Geology Hub! New eruption just started just north of grindavik, it was very close to the town. Update: the eruptive activity dropped by 90% in only few hours after the eruption started. So it follows the December 18 pattern
I have been to Diamond Craters. It seems much younger than geology claims due to the dry High Desert environment. Low precipitation and sparse vegetation breaking things down.
Cool I didn't know about this eruption and appreciate the longer video to give us the information! In terms of the reason given what I've learned from Nick Zentner's channel it sounds like its probably related the Seismic tomography identified upper mantle upwelling feature consistent with the Juan de Fuca ridge and East Pacific Rise cutting through southeastern Oregon. It kid of looks like the shallower Cascade subduction zone is somewhat getting dragged with North America while the rest of the ridge system due to it being anchored deep in the mantle is staying within the Pacific/Yellowstone hotspot frame(As Yellowstone appears to have been a ridge line hotspot much like Iceland which is chemically discernable from its past eruptive products signature and the current mantle geometry observed in Seismic tomography. It even looks like all those subducted slabs are getting dragged up into the path of the plume but unable to pass or something equally complicated.
Was there about 8 years ago, one of the nicest parts of the area is it is well off the tourist routes so you can wander and explore the area in piece - unlike much of the Cascades.
Wow! I feel like Diamond Craters volcano is exciting and interesting compared to most but it might also just be the videos either way great job! Love all the info and keep up the good work! Any thoughts about videos on volcanoes on other planets or is that too speculative?
Yes appreciate the longer vid. Give me/us allllllll the info. Love it! Question had there ever been volcanism in Eastern US? Like even millions of years ago? Any evidence one can go see?
Excellent. I figured you would get to those other volcanoes in East Oregon eventually. I only noticed them on Google Earth because they look similar to the East Idaho fissure shield volcanoes from above, just not as large. lol (ツ) ☕☕(ツ)
I actually like the extended video...sometimes there is more in-depth information that ( from a viewer's P.O.V. ) would be good to cover but set time constraints will end up limiting such more involved information/detail.
I was expecting some diamonds in the conversation, but that's OK. Just a name? No diamonds? I kind of figured if there were diamonds there would be signs of vigorous mining. No diamonds. Sigh. I was just about ready to jump in the car and drive across the country to find me some. Great report.
Check out the "Crater of Diamonds State Park" in Pike County, Arkansas, if you would like the chance to do some digging for diamonds. If I recall correctly, there are also gem-quality topaz which can also be found there - whoops, no, I just checked. No topaz there, but you might also find some amethyst.
Right now in Oregon, we are freezing, coldest weather in 30 years 🥶. Snow, freezing rain, fierce winds and temperatures are 17 (with windchill 1 to -7). This is Portland, our mountains are so much worse. I know it’s no big deal to several states, where this is just another winter day, we’re just not use to it. My husband just laughs, he’s from Wisconsin and then moved to Chicago, before Oregon 😂
I’m from northern midwest so the cold doesn’t bother me as much as it does people who grew up in the south. Explorer Peary brought some people from the arctic to America and they couldn’t stand how hot it was. I think they died from heat exhaustion.
@@edwardlulofs444 It is clearly documented in Peary's papers that the ones who didn't make it home died of European-origin illnesses. The heat wasn't comfortable for the people of the North, but it could be fatal for the sled dogs. A periodically rotating display of extracts from his papers are available for public viewing at the Admiral's summer home at Eagle Island in Maine. (Alas, the house itself is apparently temporarily closed for repairs by Friends of Peary's Eagle Island and the State of Maine.)
Same here, but in Choctaw, Oklahoma. Will be hovering between 10 and -2 degrees until Tuesday. For us, this started in February 2021, with the cold temps that brought Texas to its knees. Each winter since, we see cold not seen for generations. Trying to bring in stray cats yet again. Nearly impossible for us here to believe in a rise in mean annual temperatures, when the winters have become so brutal. And I fully realize areas in the north experience much colder temperatures. But our infrastructure wasn't built for this, and our wildlife is struggling, and has been diminished.
Since contained water becomes supercritical at 373 degrees Celsius, water causing volcanoes to explode would be too. It's a nifty scientific phenomenon if you wanted to cover it. Water at 600C suddenly released explodes with the same power and speed of black powder! Talk about lava bombs.
Often strange numbers appear when converting a round number in one system to another system. If usgs used 4 miles deep, that’s about 6.2 km. Or there might be an important geologic structure that such as the Great Unconformity. Or a weak layer of shale between hard layers of limestone.
No diamonds those require volcanic pipe eruptions which are believed to be rapid geological chemical reactions where under the right circumstances carbonates in the mantle can geochemically interact with continental silicates to trigger something sort of analogous to a bottle rocket as the bulk carbonates decompose back into carbon dioxide. Depending on the composition of the overlying continental plate they can take the form of Lamproite pipes (generally from "younger" Proterozoic to present aged crust) or Kimberlite pipes (continental crust generally from the Archean aged cratons). Both can excavate any diamonds that were in their path as they curst up from the upper mantle to the surface in a matter of hours to days but Lamproites rarely excavate diamonds compared to Kimberlites possibly related to geological evolution of these continental systems over time. For context most diamonds formed billions of years ago and were deep within or below the cratons only to geologically recently become ejected at a rate too quick for them to revert into their chemically stable low pressure form of graphite. Oregon crust wise is much too young compared to the billions of year old continental crust that yields diamonds.
Definitely. I just commented about this to someone else. The "Crater of Diamonds State Park" in Pike County in Arkansas. You actually CAN find diamonds there.
Evidence? Assuming you have got some (presumably from at least one published paper in the scientific literature), this is something that GH and other channel members with a serious interest in the area ought to know about.
I love the info but sure wish you would just speak with your normal voice instead of the RUclips documentary diction. I actually stop watching as soon as I hear it, anymore. I'm really sorry and not trying to be mean.
I also enjoyed the longer format. Your videos are always good, but this one is exceptionally good - one of the best you have ever done.
I'm always amazed at how many diverse volcanic features are in the Pacific Northwest that are so poorly-known. Really appreciate the videos.
I say that, I greatly enjoyed the longer format here, feel free to sprinkle such longer content through the standard format as you see fit.
As an Oregon resident, I really appreciate your videos on the area, as most are about things I didn't even know existed.
Spoiled for Oregon content recently!

This would be so wild to see in person
Remember, you can visit (in the U.S. BLM area)!
After Hawaii, Oregon has the highest percentage (@86%) of volcanically formed terrain in the US.
Always enjoy learning about my states geologic history
Super awesome cool and rad all in one video
Fascinating. Wonderful detail that helps me to understand volcanoes better. I didn’t even notice that it was longer until you mentioned.

Were diamonds ever found at Diamond Crater?
👍

I wonder if there's a well documented eruption that coincides with local native mythology?

So can people go hunt diamonds there or is it only a name...ya know like in Arkansas
It’s named after the nearby town.

New eruption in Iceland 2024
Your geologic settings diagram has been proven to be wrong with the new mantle scans they have been able to make.

@davidcranstone9044 well I used to but I can honestly say when I check my links there 404ed in the website so 🤷 I guess not anymore......
The sound of a boring professor
Will a volcanic eruption ever cause the earth to split in half. Then fly off into space and got out of its orbit around the sun? If not why not?
"If not why not?" - gravity.
I love the info but sure wish you would just speak with your normal voice instead of the RUclips documentary diction. I actually stop watching as soon as I hear it, anymore. I'm really sorry and not trying to be mean.
