Ok that's the last in Southern Idaho playlist. I'm really impressed that Southern Idaho has a great diversity of Geology to look at and great stories for you to investigate. This must be newly made, your camera work, story, over all comfortableness in front of the camera really shows that your a veteran now. Very well done! Thank you, Professor for making and sharing these videos!
@@shawnwillsey Thanks Professor! LOL that was an insane amount of Videos! And you were popping them out faster than I could watch them! Really enjoyed all of them. I feel Geologicly enlightened! Thank you very much!
Thank you for another enjoyable and educational video, Shawn! Exploring the Little City of Rocks in Idaho with you and learning new stuff is the best way to start the weekend :)
It looks like about every 2 million years it makes a 50 mile movement (NA plate). YPVF started about 2MYA, so I expect "The Big One" soon. I live in PDX Basin so you see my concern. THX for the field vids.
Some what reminiscent of the Chiricahua National Monument in Cochise County AZ. A similar origins just not the result of a hot spot. Mostly Rhyolite Tuff.
QUESTION: Much is made of this hot spot and how often it has erupted. From what I have learned from Ned Zinger it was passing underneath areas with extensive faults, terraces, and relatively thin crust. As it passes under increasingly thick crust could the eruptive period increase or even cease over time. I recall reading that the New Madrid earthquakes of the early 1800s were felt over a very large area due to the thickness and perhaps also density of the crust in the central part of the North American continent. I am from Michigan by the way and deal with bridges so my professional concern tends to end before our borings hit the first rock layer. Or if we hit it we only continue if the first layer seems to be heavily weathered which is rare and only occurs in a few areas where I have worked.
Pyroclastic flow, vs, fissures of magma flowing up from the faults caused by the massive earthquakes into the land that eventually eroded away leaving these spires of magma which could have happened during a snow storm or a hard rain.
These rocks look similar to rock formations by the Ririe resevoir in east Idaho. As you go down into the canyon towards Blacktail boating area I see many formations like this. Have you studied these to see if they are of the same type?
Love your stuff. How can ash be below its melting point when ejected in a volcanic eruption, then get heated enough to melt after falling on the ground? Where is the extra heat coming from?
GO SHAWN! (And thank you very much, for the information! That is amazing now that I have watched most of this so far! Ancient molten volcano ash, along side nature’s weather! Beautiful!) P.S. I will certainly send money to support your profession/channel/pursuits! Once I get to the point when I can afford to do so. I’m still only 33. But have a whole lot of potential in a couple of trades, at work and home! Which is why I work 80-100+ hours a week! Time will tell. But one thing is for sure. I will be working as hard and smart as possible until I’m literally too old to do so! Have a great weekend Shawn! I will be working basically all weekend like normal! Also, greetings for Indiana! Right across the boarder from Cincinnati, Ohio! ❤️
And there is a minor geothermal water feature, WNW from the main area shown, but it is only lukewarm. It is shown on the Google map if you look closely. Difficult to get to, no trail, not worth it if you want to soak. I took pictures and left. Interesting.
Thanks again for another excellent lesson. So at what rate do you need to cool the deposit for phaneritic crystal growth and does that make sense based on how it was depositied?
@@jackbelk8527 I was wondering if anything could have been preserved below the ash, the "Pompeii effect". It might be interesting, but that flow was pretty hot and could have incinerated everything.
What most geologists won't admit, is that Yellowstone, as well as the Olympic Peninsula and the Columbia River Gorge up to Snake River and Couer dAlene lake, is these were both ancient Central American hot spots, that with detached portions of a once-massively thicker landmass, detached from the western flank of Central America (Mexico to South America shoulder), as the North American craton twisted clockwise, and moved south and west, while the entire Pacific ocean bedrock moved north and east, these 2 different hotspots were moved up into the Pacific Northwest. When these landmasses (Olympic Peninsula "Siletzia") "landed" onto the proto-West Coast of California-Oregon-Washington, these landlocked hotspots then moved under the moving craton eastward into their final locations locked up against the Rocky Mountains and its tremendous resilient granitic structure. As such, the Yellowstone hotspot trail can be traced with hotspot volcanoes have been dated, and proven its curvilinear arcing. In the Siletzia condition, the hotspot of the (later) Olympic Peninsula stepped off into the Washington-Oregon border, move up and "SINTER" the bedrock, upward through the Columbia Gorge, leaving Beacon Rock granitic plugs sticking out of the eroded landscape, SINTERING the anomalous YOUNG southern Cascades (barely 40,000 years old), while the northern Cascades (crystalline structures) remain as the original bedrock and tectonics. This hotspot continues up into the eastern Washington/Oregon scablands, leaving such traces of prior resting spots (confirmed by Shell gas oil drilling operations across Washington) with 1 mile deep volcanic pipes, ... eventually moving up the later Snake river, and boucing up against the Rockies, leaving a hotspot that cooled down into the Couer DAlene lake geology. This is not admitted for either of these 2 hotspots of the Western North America, because it shows that all of the equatorial volcanic actions (multiple volcanoes in each of the Central American nations) did split off, and move like the San Andreas/San Francisco fault zone landmass, and the current split-off landmass of the Grapevine north of Los Angeles to Baja peninsula is the most-recent splits and northward movements. Just like Mount Stevens in central Washington, that zircons have ABSOLUTELY SHOWN to be associated with Central America, that geologists refuse to admit such landmass splits and plate tectonic movements. When geologists finally pull their head out of their (------) and admit that this planet fractures, and sends off portions of landmasses, it will solve so much geology of the past. It is the same in collateral proof that in eastern Washington (Vantage Ginkgo petrified forest) and eastern Oregon (John Day fossils) that they find Coast Cedars and Ginkgos that are ONLY indigenous to southern China and northeast Australia. The only way these trees could have translocated, was when China, Australia, and the proto-West coast of North America were located in the equatorial zone of Central America, before splitting off and moving apart. Further proof is that the (said) Iridum asteroid of ~60 MYA impacting Chicxulub Yucatan, creating a 110 mile x 110 mile impact crater in the Gufl of Mexico waters, sandstone, and limestone, burying a 6 mile diameter asteroid 12 miles deep. This WAS NOT the only asteroid to hit the equator, as the above said Siletzia hotspot, the Yellowstone hotspot, ... and now 2 different Utah Uintah basin impact zones prove that there were further asteroid companions to Chicxulub. The Uintah basin (ahem) 110 mile x 110 mile area is the same size as the Chicxulub. This asteroid did not impact as deep into the depths of the proto-Rocky Mountains area, due to sandstone and harder geology, leaving this suspected same-sized asteroid only buried 3-4-6 miles deep and having geomagnetic anomalies in the region. This is Skinwalker Ranch near Vernon, Utah. A smaller asteroid chunk hit a little nearby and southwest of this previous impact, and its geomagnetic (et al) anomalies are found in the Blind Frog Ranch location. This smaller asteroid fragment is virtually near the surface, ~50+ feet deep, and being discovered by the local property owners there. The Siletzia and Yellowstone impact zones, now obliterated, eroded, and covered over, ... were also asteroid impacts of the same or lesser size than Chicxulub and the Uintah basin. So Siletzia and Yellowstone were another set of these now dinosaur and planet killer asteroids. And a final connection is the 5 (newly discovered) super magma chambers buried under the Siskyou-Klamath mountains in the Oregon-California border. This location is what is holding up the San Andreas/San Francisco landmass from moving northward. If this cracks and opens up, then all of California will become Alaskans, Canadians, and Pacific Northwest Washington and Oregon residents. If the Grapevine of a triangular basalt zone snaps, then Los Angeles to Baja moves north. If this also provokes the Siskiyous to snap, then either the north moves, and then the south moves, or the south moves then the north moves. In effect, the entire West Coast of North America will have travelling papers for the next millions of years into the north Pacific regions. Don't take geological, volcanic hotspots and (super) magma chambers as their explicit volcanic location origins, ... as they originated from even greater astronomical events ... then translocated to other locations in times past !!!
Hmm some interesting information if true do have some sources on the central American position links? That part does fit the picture where North America is getting sheared relative to the East Pacific Rise and its hot spot frame though to my knowledge while large latitude offsets are well established explaining how those offsets happened i.e. what translations they occurred along seems to be the controversial part. Given the current clockwise rotation I have long suspected that differential translation is a possible mechanism whereby many faults and internal rock deformation accommodate the strain of translation. The claim about impacts within the protorocky mountains is potentially plausible since there is evidence that there was a substantial number of impact events during the late Mesozoic into the early Cenozoic of which maybe 4 or 5 could potentially have happened concurrently to Chicxulub, but I've not seen any evidence for this proposed impact site do you have sources here? Proving a structure has an impact origin is difficult without shock cones or shocked minerals typically quartz. As for what is holding back the translation of crust I'm pretty sure the main driver there is the current position of the Subduction zone and the areas where the Gouda ridge a sub system within the East Pacific Rise complex in the mantle appears to pass beneath North America. After all if the underlying mantle beneath the Basin and Range is oceanic as it appears in Seismic tomography with a thin increasingly stretched out thrust sheet of continental crust on top of an asthenospheric weak layer then it is the large translational offset between Yellowstone and where the EPR emerged as the Gouda and or Juan de Fuca ridge. Incidentally an interesting possibility emerges from the finding that Yellowstone Hot spot signature melts started to erupt along a very specific lineament through the Cascades. In particular the East to west line of volcanoes of which Mt. St. Helens is the most famous example has volcanism occurring both closer and further from the trench than is typical of a subduction zone. The Yellowstone met signatures are typically suggested to be remelted crust from Siletzia however seismic tomography shows that the subducting slab is undergoing thinning below this region directly paralleling the Snake river plain almost as if the East Pacific Rise is trying to reestablish a more direct boundary compared to the roughly "v" shaped indent aligned with North America's relative direction of motion. And notably there is no evidence of a subducted slab east of this buoyant upwelling zone that cuts through Northern California and Oregon. Basically it seems possible that the EPR as a deep rooted MOR is on geologic timescales reestablishing its heat flux outlet to more directly underlie the deeper mantle signature of the ridge which if this comes to pass would bring westward dipping subduction into the Pacific plate mantle current block itself. This if it occurs might lead to California and the Basin and Range instead forming an oceanic archipelago built out of former continental crust which could begin to close the Pacific from the East while the Pacific ocean continues to grow/expand east of this arc in essence potentially leading to the gradual orphaning of the Pacific plate from its MOR depending on if the Gouda ridge remains active enough to persist once separated from the primary heat flux and zone of extension. The idea of westward dipping subduction to the west of the East Pacific Rise is such a strange but interesting thought that could lead to some complex tectonic evolution perhaps most similar structurally to New Zealand. For example while we might expect it to at least initially continue to move north within the Pacific frame the development/accumulation of a slab wall in the mantle might eventually anchor into the mantle slowing and or halting its relative northward trajectory rather than ultimately rejoining with Alaska. But how much slab down there would be needed to anchor such an arc. There is also the question if with the additional continental lithosphere one might get the subduction zone expanding south.
@@Dragrath1 Sources to check - - Vantage, WA Ginkgo fossil state park, 40+ different trees species were recorded by a WA geologist, of which Ginkgo and Coast Cedar are Asian/AUS. - John Day, OR fossil beds state park, same trees - Uintah basin, same 110 mile x 110 mile area, same as Chicxulub. Yucatan is buried 12 miles deep and 60 million years hiding underwater and only the discovered shock ring located it. Uintah basin has undergone massive erosion into the basin, as well as Rocky Mountain tectonics uplift, distortion, of a once Western Inner Seaway from Canada to Mexico, 2000 miles wide, 400+ ft deep (shallow sea), eventually run off with tectonic uplifting Midwest sloping down to Gulf of Mexico of the Missouri-Mississippi river watershed basin. Dakotas are 1300+ ft in elevation, as well as the Canadian border. All these movements, uplifts, distortions, erosions have covered over and eroded the shock ring, but geologists admit that it is a basin with erosion infill. - Siskyou-Klamath Oregon-California border forest. Vancouver, WA Mt St Helens volcano observation center, and their recordings of earthquakes found these (and they are migrating !) super magma chambers that rival Yellowstone. This area is the landed area east of the Gordo/Gordo ridge where all of the major EQs are happening - and said to be the lynch pin to causing M9 EQ of the Pacific NW. Hotspot, Pacific plate (Farallon, Juan de Fuca, Gordo plates) all pushing under North American craton. - WA geology of the sintered southern Cascades of WA that no geologist understands how, who, why, when (or how) - but can only come from a transitting hotspot that fried that geology and left it, as the hotspot continued eastward. - Grapevine basalt triangle, recent EQ swarms to the eastern point of the eastward pointing triangle. Look Google maps for aerial view and this became apparent to me, as it is holding back entire LA to Baja landmass - otherwise LA etc would be sailing north with ease. - Known solar and lunar (and solar-lunar) tidal forces at equator raises and drops land 4-6 inches every pass. No wonder lithosphere and volcanic-tectonic plates can fracture the western Central American coast line, then inchworm them up the west coast, until they land, and become each successing proto-coastal geology of the area - Mt Stevens central WA zircons controversy still being debated by the Out of Mexico - and - no they aren't groups - AUS geology vids on YT mention their association with Ginkgos and Coast Cedars when AUS and Asia (China) were conjoined together. Thus, the only way AUS-China could translocate these 2 tree species was an equatorial location at/during/before/after the Chicxulub asteroid impact time, and the shattering of Pangaea, with resultant Pacific midridge rise and expansion of the Pacific Ocean moving AUS-China away from the Americas. - Growing up in Portland/Vancouver, always wondered about the "Z" formation of the Columbia River, ... and it became apparent in recent discoveries and years, that this width of the WA/OR coastline, associated with the geologist mentioning Siletzia as an island that then became locked onto the coastline. As such, that hotspot when the Columbia River was straight out to the modern locations of Astoria OR/Ilwaco WA, has now moved (in that clockwise rotation - known by WA and OR geologists circling around the eastern Oregon batholiths, that the hotspot detached and started moving up the Columbia, while the landmass of the ancient territories eventually (at present) is up near Seattle and Vancouver BC. The hotspot curvilinear arc, is the same as the Yellowstone trail. The Siskiyou magma chambers were also translocated, and for other reasons, like the Gorda and Pacific plate, at that location keeping them stationary. This locked down the Olympic peninsula to OR/N CA into place, and the Siskiyou magma chambers remain intact and stationary holding back all of California from sliding north. - Review Wiki volcanoes of Central American nations, and it becomes obvious with solar and lunar tidal forces why equatorial regions, especially on the Pacific Ring of Fire (versus other locations elsewhere at the equator) why volcanoes, zircons, and fractured and separated landmasses were calved off a once-vastly huge width of Central America, that is now a bare resemblance of itself. - and there is so much more to link.

But how much slab down there would be needed to anchor such an arc. There is also the question if with the additional continental lithosphere one might get the subduction zone expanding south.

All these movements, uplifts, distortions, erosions have covered over and eroded the shock ring, but geologists admit that it is a basin with erosion infill.
- Siskyou-Klamath Oregon-California border forest. Vancouver, WA Mt St Helens volcano observation center, and their recordings of earthquakes found these (and they are migrating !) super magma chambers that rival Yellowstone. This area is the landed area east of the Gordo/Gordo ridge where all of the major EQs are happening - and said to be the lynch pin to causing M9 EQ of the Pacific NW. Hotspot, Pacific plate (Farallon, Juan de Fuca, Gordo plates) all pushing under North American craton.
- WA geology of the sintered southern Cascades of WA that no geologist understands how, who, why, when (or how) - but can only come from a transitting hotspot that fried that geology and left it, as the hotspot continued eastward.
- Grapevine basalt triangle, recent EQ swarms to the eastern point of the eastward pointing triangle. Look Google maps for aerial view and this became apparent to me, as it is holding back entire LA to Baja landmass - otherwise LA etc would be sailing north with ease.
- Known solar and lunar (and solar-lunar) tidal forces at equator raises and drops land 4-6 inches every pass. No wonder lithosphere and volcanic-tectonic plates can fracture the western Central American coast line, then inchworm them up the west coast, until they land, and become each successing proto-coastal geology of the area
- Mt Stevens central WA zircons controversy still being debated by the Out of Mexico - and - no they aren't groups
- AUS geology vids on YT mention their association with Ginkgos and Coast Cedars when AUS and Asia (China) were conjoined together. Thus, the only way AUS-China could translocate these 2 tree species was an equatorial location at/during/before/after the Chicxulub asteroid impact time, and the shattering of Pangaea, with resultant Pacific midridge rise and expansion of the Pacific Ocean moving AUS-China away from the Americas.
- Growing up in Portland/Vancouver, always wondered about the "Z" formation of the Columbia River, ... and it became apparent in recent discoveries and years, that this width of the WA/OR coastline, associated with the geologist mentioning Siletzia as an island that then became locked onto the coastline. As such, that hotspot when the Columbia River was straight out to the modern locations of Astoria OR/Ilwaco WA, has now moved (in that clockwise rotation - known by WA and OR geologists circling around the eastern Oregon batholiths, that the hotspot detached and started moving up the Columbia, while the landmass of the ancient territories eventually (at present) is up near Seattle and Vancouver BC. The hotspot curvilinear arc, is the same as the Yellowstone trail. The Siskiyou magma chambers were also translocated, and for other reasons, like the Gorda and Pacific plate, at that location keeping them stationary. This locked down the Olympic peninsula to OR/N CA into place, and the Siskiyou magma chambers remain intact and stationary holding back all of California from sliding north.
- Review Wiki volcanoes of Central American nations, and it becomes obvious with solar and lunar tidal forces why equatorial regions, especially on the Pacific Ring of Fire (versus other locations elsewhere at the equator) why volcanoes, zircons, and fractured and separated landmasses were calved off a once-vastly huge width of Central America, that is now a bare resemblance of itself.
- and there is so much more to link.
Very interesting. A bit over my head, but food for thought and further research.
