Idaho - Resurrection Plate w/ Spencer Fuston

[@hertzer2000]

Well, that was fun! Gonna watch it 3 more times to see if I can understand it!

[@RichardStephens-lq3ou]

Congratulations on the new member of the clan

[@rayday7724]

Thanks, Nick.

[@inqwit1]

This Idaho series: unimaginable that we find ourselves in the midst of geologists sharing their perspectives about the same area. Enthralled to be a part of the conversation. Thank you.

[@Siletzia]

The Siletzia-Yakutat story since 56 Ma is indeed a hornet's nest, particularly with respect to Yakutat. I have been reading everything I can get my hands on for a few years and trying to synthesize a S-Y story that is more or less without holes, and we're all far from there. Erin Donaghy will have something important to say about Yakutat when her paper comes out this fall. That might be a good time to have her on. And, my goodness, Spencer's upcoming paper will undoubtedly be a blockbuster. Can't wait for that one too.

Every episode is a joy to behold and listen to. So many interesting subjects are discussed. And always with an open and curious mind. Wanting to learn, wanting to understand. If that isn't science I don't know what is. Thank you! ❤

[@PlayNowWorkLater]

I love that you pretty much have an arsenal of specialist geologists that you can call on to these presentations. Great stuff, as always Nick!

[@geoffgeorges]

THIS IS GOLD! Thank you both, so informative.

[@GregsGeologyChannel]

This was an excellent presentation! We lose track of time and go with the flow. 😀

[@pmgn8444]

Thanks Spencer and Nick. Fascinating as always. I'm loving the 'Idaho Miniseries!' It's addressing question I've had since Exotic Terranes A to Z. Also, congrads Grandpa Nick! Glad to hear mother and (grand)child are doing well.

[@bearbait49]

I agree with canceling the event, having lived with wildfire most of my life that was not looking good. Let’s hope there will come a time we can join these two fine geologist educators in the field. Really enjoying this series.

[@LeahC208]

Not doing live streams can't really be an option!? Can it? Lol this is so good for our community and for the Geologists as well. Keep up the good work.

[@EShelby2127]

*E X C E L L E N T !* As always, and CONGRATULATIONS!

[@yukigatlin9358]

A triple junction, yeah! 😃✨Oh my, Spence Fuston, you gave us lots to think about with your unique takes on various geological interpretations... I was pleasantly sucked into your conversations with Nick!! Thank you Nick for once again making this happen!!💞💗✨Grandpa Nick is a wise man!!😉✨

[@michaels6897]

Littleton, colorado, been watching vids for a while, thanks Nick

[@diblust53]

Hello from Willamette valley OR. Another really great session!

[@fr8trainUS]

That was a quick 2 hours. I enjoyed it

[@roddixon368]

Thanks, I love your work on your part of the Pacific rim and relating it to our part to the north and east of Australia. Wonderful area of our world, that will keep you and I busy for years.

[@Kyle-b5x2k]

I don't mind 2 hour streams as long as they're content rich!

[@cindyleehaddock3551]

Congratulations 🎉 on the wee one! Sorry about the fire. Thanks for another thought-provoking video on Idaho!

[@keyscook]

Interesting discussion - I'd say it's beneath me but that would be a bad pun! Cheers from Seattle!

[@Dennis52947]

Caught the replay!

[@Poppageno]

Nick; We need a 3d animation to help with visualization. Congratulations to you and Liz and of course the proud parents on the new addition to the family! Thanks for bringing Spencer in. You're doing a great job!

[@robmagee100]

Fascinating and brilliant discussion. Spencer’s analysis and illustrations of the plates, the hydrodynamics, the interactions of relative mineral density driving the slab motion (the concept of plates being pushed along the upper/lower mantle boundary was a new one to me), all under the principle of Occams Razor and corroborating examples…. Really resonated with me. I hope to retain this in my mind, which is somewhat like a steel sieve…. Thanks again, Nick and Spencer!!!

[@markbrideau588]

Thanks Nick for another great talk on Idaho 😊

[@guiart4728]

Another fascinating program! Thanks Spencer!!! You’re doing a great job Nick!❤️❤️❤️❤️

[@cyndikarp3368]

Siletzia collision is an amazing part of Northern California to Canada Coastal Range Volcanic history. There seems to be three ocean based spreading zones? Yellowstone hot spot cut to the mantle to present location. Northern spreading ridge Oregon & Washington. Alaska spreading ridge, which is still a mystery to me. Siletzia collision continues to put pressure for West Coast rotation with current strike-slip of Pacific plate & North American plate pressure? Is Basin & Range rotation enhanced with Rio Grande spreading ridge splitting Colorado in half? Dotsero volcano & Steamboat Springs to the north expanding to the south? Caused from Mexico movement? Can an old strike slip convert into spreading ridge? When movement changes as plate tectonics progress? Can transition faults convert into spreading zones, as the collision of ocean plate dives, sometimes splitting into spreading zone? Great class today. Thanks

[@marinangeli3250]

Dang it... I was so looking forward to the event in Stanley (my old stomping grounds from my misspent youth). 2024 has been the worst year ever for me and a little R&R in my favorite place on Earth, listening to my two favorite geologists, would have been very nice, indeed. Lost my mom in March, but couldn't travel to California to say goodbye because my companion of 28 years was too ill for me to leave. Lost my companion at the end of July, after over a year as his 24/7 caregiver. As per his wishes, I'll be scattering his ashes at his favorite spot near Stanley, when conditions allow. Now I am losing my beloved forests of the Sawtooth Range. This just too much to bear. I'll be ok but, for me, the world has changed forever. I am grateful Al didn't live long enough to see the tragedy unfolding in the Sawtooths, which we both loved so dearly. My video about the Atlanta Lobe of the Idaho Batholith, specifically the Sawtooth Range, feature's a song he wrote in 1971 (High Mountain Snag), inspired by the gnarled remains of whitebark pines he encountered while hiking those mountains in his youth. Thank you, Nick, for doing this Idaho series... it is a topic that is near and dear to my heart. The complications of my life kept me from watching in real time but I have diligently been playing catch-up over the past week or so. It has been both educational and therapeutic. 💕

[@carolwillett5495]

Gracie Willett age 14 says congratulations Nick on your grandson.

[@hjumper8238]

I saw a notification about this release yesterday, however at that time I was not in any proper state of existence to be able to participate either live or shortly thereafter. Having just finished viewing this I am joyful that this delay in no way impacted the value of the information this contains for me. Thank you, again Nick! As I was listening from the beginning, I felt handicapped that I do not fully understand the orogeny evidence already available to us, and briefly imagined if I could stop time and sit through an introductory class about Orogeny 101 from Karin Sigloch. Ha, if wishes were fishes! I also wonder if there exists the scientific discipline of Plate Tectonics studies that roots itself in the physics of Earth Mantle Physics? Without any regrets of ill preparedness of background information, I remain captivated by the direction you are taking us Nick. I continue to ask myself, why am I so interested in this and why do I care? For me, I don’t think answering those questions are as important as the fact that I do and satisfied that this platform exists for my enjoyment. I make no excuses for my apparent selfishness, and I am truly grateful for your generosity, Nick.

[@johnmohr1447]

Here's an idea. Do a special edition of "Nick Looks Back" and bring in Muffler Boy to ask the question, "What were you thinking?"

[@jamiewilson8338]

Watching after allows for extra inclusion since I couldn’t accurately use full Geo terms. Thanks viewer’s!

[@garypaull9382]

Great stuff! I had previously envisioned Ohanapecosh times looking more like the Indian Heaven volcanic field so this is good to learn! What is this "ocean" that the Ohanapecosh is belching into? Siletzia has already accreted after all. Some volcanics of similar age also happening within the nearby Puget Group too. Exciting times in the Oligocene for sure

[@SCW1060]

Hey grandpa Nick. I hope all went well

[@deantheot7296]

Hey Nick, Sorry I was late but I got the ending. I really appreciated the maps at the end because, like you, I have been baffled by where'd all the plates come from and go. Overtime is always welcome for us viewers. More to think about and look forward to in the future. Take Care, Sir. Hope to see you next time.

[@Poppageno]

So much we don't know, O' for a time machine! ?'s for Spencer; When do you see the Cascadia subduction zone forming? If it was at the time of Basil's "hit", 100Ma, would it not be further North than Georgia? Would the hit and going from westward subduction to eastward subduction be enough to cause slab breakage and a slab widow? Thanks for sharing your knowledge with Nick and us!

[@Csuttell]

If a slab breaks off, it seems like two things would happen, 1) the pull on the remaining slab would lessen and thus so would the movement of that slab, perhaps subduction would nearly stop, and 2) the remaining "attached" piece would be unweighted and allowing for upwelling of mantle, this creating conditions for crustal extension.

[@jodyfairchild5446]

Looking at Spencer’s dates for the plate’s activities, brought to mind the Crystal Core’s bouncing Batholiths. Do the dates of the batholith bounces correlate with the movements of the tectonic plates? Would those plates cause currents bouncing the batholiths?

[@RichardStephens-lq3ou]

This Idaho slab, kinda reminds me of the ribbon candy you talked about a couple years ago

[@jnanadams9756]

Does the tempurature decrease of mantle material "trapped" between the subducted slab and the crust? If a break-away slab entered the verticle.current of a Yellowstone like plume, would that distrupt the plume impact on the crust influence?

[@twotone3471]

There are Lahars from the time when there were Stratovolcanoes in Idaho, welded tuffs too. So it is fairly likely that there was oceanic crust involved, rather like how the current Cascade volcanoes are today. But if one really wanted proof, it's in the welded tuffs, which have preserved chemically what was erupted.

[@GregsGeologyChannel]

Maybe a deep horizontal slab is a better term than flat slab?

[@markhamburger5587]

would be nice to have all this as a more concise presentation like Nick used to do for the public on stage. How about that?

[@wildwolfwind6557]

If the Yellowstone hotspot and the Idaho slab curtain are both relatively stationary and the west coast of North America was east of the Yellowstone hotspot 60MA (prior to the accretion of Siletzia) how is the Idaho slab curtain west of the Yellowstone hotspot? Shouldn't the slab curtain be to the east of the hotspot if the break was caused by Siletzia clogging the subduction trench? The Idaho volcanic arc and subduction zone were to the east of the hotspot at the time of the break - right? 🤔 Could the subduction zone trench for the Idaho volcanic arc be west of the Yellowstone hotspot (& Siletzia) while the Idaho volcanic arc was to the east of the Yellowstone hotspot? 🤨😕 😻💖💞❣

[@thegallantgoosefriends9123]

Q: DOES THE EASTERN EXTENT OF THE CASCADIA SLAB OF THE FARALON PLATE ROUGHLY MATCH THE CONTOUR OF THE DEEPEST PARTS OF THE GREAT NORTH AMERICAN CRATON (CANADIAN SHIELD)?

[@66kbm]

And i was looking for Volcanoes????...WOW.

[@thegallantgoosefriends9123]

Q: CAN THE EASTERN EXTENT OF THE CASCADIA SLAB OF THE FARALON PLATE AT THE LATITUDE OF MISSOURI AND SOUTHERN ILLINOIS EXPLAIN THE NEW MADRID SEISMIC ZONE? (OR AT LEAST CONTRIBUTE)

[@johnnash5118]

Hello Spencer, I sincerely respect and appreciate your presentation as a whole; but after reading your GSA bulletin publication, I have trouble reconciling the bent spreading ridges and resultant flow conflicts of the adjoining Farallon, Kula and Resurrection slabs in the diagrams on page 6, figure 5; these modeled geometries should, but do not include subduction accommodation and are missing fracture zones and perhaps more offsets, resulting in inter-slab oblique convergence without any accommodation mechanisms. I haven’t seen any worldwide examples today of bent spreading ridges to support it as an efficacious model. I strongly disagree with the repeated notion that whole oceanic slabs move en masse, counter to their ridge-transform fault flow geometries as there is no evidence of it worldwide and is contrary to the ridge-mantle upwell flow beneath.

[@tanyatucjer]

GOT ROCKS?😊

[@thegallantgoosefriends9123]

Q: IS IT POSSIBLE THAT THE CARIBBEAN PLATE NETWORK WAS INITIALLY FORMED BY THE SOUTHERN END OF THE FARALON PLATE BEING "SQUEEZED LIKE TOOTHPASTE" THROUGH THE GAP BETWEEN NORTH & SOUTH AMERICA AS THEY MOVED WEST? IT SURE LOOKS POSSIBLE.

[@Poppageno]

Which gplates model to look at?
