Basil always rocks it. He makes complicated issues clear. Bassil also does not hesitate to say what he thinks and why. Thanks, Nick for providing all this learning.
Beautiful show. While I am not a geologist this approach with N. America drifting south, multiple ocean plates in movement, lost faults and a rugged coast line makes sense to me.
@Nick Zentner you have inspired the public to learn about your field of science and engaged people in the process of learning, evaluating hypothesis and constructing an understanding of the world. Congratulations on becoming the world most prolific teacher of science!!! I have followed your shows for several years and I have gotten caught up on this series in Dec. Today was my first time here live and I'm looking forward to the next installment. I think I can speak for the viewers in saying thanks to you and all the guests who are willing to come talk about their ideas and research.
I’m glad Nick figured out the mic issue; and Basil is such a great presenter of the global picture. He brings together so many data sets that agree with one on other.
Congratulations Nick. You have done a masterful job of assembling experts and engaging the public. These are master classes in both the science and science communication. Your are communicating the reality of research and the thrill of discovery brilliantly. Very very well done.
As a fellow recovering flusterer, I can tell you that this wasn't that bad, and to take some breaths and realise that other people aren't as annoyed and put off as you are in the moment. It took me a looooong arse time to understand that eff ups happen to everyone and no one cares as much as you think. That realisation was very liberating. Thanks for the show.
Basil is a gem! Just like the other guests and Nick). Despite the sound issues I thoroughly enjoyed this installment of the series. Again and again : Nick, I cannot thank you enough for your hard work and enthusiasm to make this possible. I love to learn together with you although I probably will never see the North West Pacific coast in the flesh/rock. Never mind. I can enjoy and love it from a distance. Best wishes for the New Year to all of you and all of your loved ones! Good health and lots of love!
Oh I wish I thought to have the video running at Lowes to show the power of leverage by expansion. They cut open a bundle of bags of insulation so I could get one and when the strap was cut it pushed a very heavy pallet of material about a foot across the floor.
I can't thank Dr Tikoff and you, Nick, enough for this particular presentation! There's been so much information to date that was way beyond my understanding and I couldn't get it to work together in my old head. Today brought some order and cohesion for some of the floating foundation material! At last! Looking forward to the next ones. Turn off all but one audio.. just a reminder! Thanks again very much!
Nick, another very informative program, I wish I was able to process all of it. Not everyone can drop a G-D then get to listen to it on a loop. Cheers, Gpa C
Nick i appreciate you saying you are dumb to some info. But thats what makes you so smart! So be dumb... cause that just means there is so much exciting information for you to learn... learning is fun! Love how you approach info! You dont know it all and you love to learn. Best way to approach anything!
I love to learn from you and all of your friends in geology. Even when technology doesn’t cooperate, I get to see you growing more with those problems because you are improving in your return game. You used to get so flustered that sometimes it nearly threw the show; whereas, now, you recover very quickly. Good job Nick!😊😊😊
After each episode, I appreciate how good a teacher Nick is, how inspired he is in choosing and interviewing the scientists he invites, how generous those guests are in sharing their knowledge with us, and Basil Tikoff is no exception in that way. His paper and his explanations are a must. Thank you to both of you.
As you probably already know, the second mic was better, no clue why. Thank you for providing a bridge with Basil. I needed that. Happy New Year, Nick.
I have finally caught up with the episodes over the Christmas holiday. Nick, you are pretty prolific in producing episodes of the superb series, so some of us cannot keep up during work weeks. However,, have no doubt that you have many, many dedicated and diehard fans that cannot make the live sessions, but are so grateful that we watch these after the fact at our own pace. I for one, watch the episodes while spinning on a Peleton….so I get a great workout and have learned about some fascinating geology!! I look forward to every episode. Thank you Nick!
I’m so impressed with the way that Basil holds the mental 3-D picture over time of the plate and block movements. The one detail that sticks in my little brain is the motion of the NA craton with respect to the North Pole. Not just a South-South-Westerly motion but also an anti-clockwise macro-rotation. I hadn’t appreciated that before. Such motion providing a driving force for these complex movements. Re viewer numbers. I had things going on around December, couldn’t keep up and needed to catch up. I watched a few in January out of sequence but I recognised the ‘holes’ that were missing so I’ve stopped and gone back to watch in order. Here we are in March and I’ve reached M. 🙄
Transpression, Transpression, Transpression!!!😃 "How" is the fun million dollar questions...💗 Thank you so much Basil for giving us geological perspectives from various angles as usual!😉 Thank you Nick very much for not giving up on those acute tech issues, and making the wonderful livestream!! You didn't disappoint me 😘💫💗
just a simple question. What is the "5x5" in the talk and chat? I guess it is something to do with the live feed zoom set up but it would be nice to know. Brilliant series - I am coming in late to the entire program and have been zipping around the alphabet here as I caught the endings before the beginnings and the middlings. I'm just an old petroleum geologist in Red Deer Alberta (Old Imperial College Royal School of Mines alumnus - 1973-1976) and fell in to this Baja BC story from another Nick Zentner podcast. I have driven through the Wenatchee and Ellensburg region and spent a week vacation in the chelan lake area and I zip back and forth through all the interior of southern BC and the Islands quite a bit too. (Family in Vancouver and many vacations on VI and the Gulf Islands over the years). My last assignment was solving a reservoir production puzzle in the Cambodian offshore last year and so this set of puzzles is really intriguing. (But my field is reservoir rocks and I bailed out of all these igneous and metamorphic rock waay back after my first year geology. I do know a granite from a gneiss - but get lost as far as diorites, dacites, tonalites and andesites are concerned.
I appreciate and love what you are doing here posting all this valed geologic content and a view of a professional doing his thing an worries the class room and any other students via cam students get the information correct to connect to each individual I have no clue what it's like I love you for being an amazing person who can open up my mind thank you so much I have never considered going back to school til seeing you sorry for the run on
Thanks Nick and Basil, I am a non the wiser but confident that I am not alone. It is wonderful to be treated like an adult and not to be given answers but ideas to mull over. I am excited about reading more in an effort to try and understand. I think that is your intention(?). If it is? It is working with me!
Awesome episode!!! Although all of your guests are outstanding, Dr. Basil Tikoff is maybe the best. Brilliant, innovative, humble, and down to earth….his work is SOOOOO IMPRESSIVE. He does a great job explaining complex topics and ideas. His “Hit and Run” theory is incredibly interesting and compelling. Loved how (1) he talked about building upon the ideas of past geologists, (2) how he emphasized the need to “follow the data…all the data”, and that (3) while he has formulated the “Hit and Run” model because it fits more of the data than past models, he assumes his model is not correct because all models eventually become incorrect as more data becomes known. Dr. Tikoff seems to be the epitome of the what a great, open minded scientist should be.
What I got from Basil is that things don't hit and run so much as hit and smear. You have two whales in the pod (Insular and Intermontain) not one. The whales are being run over by North America, getting shoved first south (a little bit) and then north (a LOT) along old North America ... and everyplace old North America sticks out, things get torn, smeared, crumpled as the outboard part continues north while the inboard part gets stuck behind the promontory. This also means there can be torn/smeared/crumpled terrain along the interfaces between the Insular and Intermontain as well as between Intermontain and old North America. These aren't smooth ribbons, these are jagged bodies, and things can get torn off and trapped while the rest of the whale moves. Because the Klamaths stick out, the story there is complicated ... and in a way, the Klamaths STILL stick out, it suddenly makes sense why the triple junction is at Cape Mendocino and why there is a tear between the Gorda plate and the Juan de Fuca plate.
The audio sorted itself out and wasn't too distracting earlier. Basil did an excellent job of explaining the Hit and Run. I hope to be able to watch the next episode live.
I would like to hear you include Siletzia in the conversation. Even though the accretion of that terrane is so much younger than the Baja-BC movements to leave it out of the puzzle leaves one piece missing.
Wow, Thanks Nick and Basil, So interesting what peoples are wrestling from the ground. Nick, as you know I'm a long time viewer and I know that for years you've had an interest in the local geology. I think we have both found the PNW story to be a larger regional story, one I think will be hemispherical in size. Plus it spans MILLIONS of years! Happy New Year to my fellow Zentnerds!
Nick, please thank the peanut gallery for the awesome questions that propelled Basil's lecture, especially the questions and comments regarding the Palouse Clamaths. Those questions helped.
I'm glad to be back. Paull,the calendar is so amazing. I will keep up live when I can. January is doctor appointments like crazy and will force someone watching the posted video. I will be happy to have surgery the 27th to get a new pacemaker. Time to replace battery. I didn't get as much studying done in the break as I wanted to do. I watched a bunch of Shawn's videos during break. To Basil, today your beard reminds me of Dr Marco Bicciari, who was one of several anthropology professors I studied under from '68 - '76. You helped me today to understand this geology better today.
Late but wouldn't miss an episode. Are you in line for some of the snow and unusual weather? Audio is scratchy. 2nd Mic so much better. lost video completely. Mic still choppy. Basil is great as usual. Look forward to the next shows.
When i first heqrd of Baja BC l envisioned a mega style San Andreas fault situation. This make much more sense imo. One thing I'm wondering about is there a current day analog to a fixed subduction zone out in the Pacific basin. Could the Marianas or Philippine Trenches fit the bill?
> Dickinson, W.R., and Lawton, T.F., 2001 is referenced in the 2022 Hit and Run paper but unfortunately out of our lay direct access. Is it within the domain of this education platform to bring that paper in, to view?
Unfortunately, my work schedule and your live broadcasts don't line up well, but I always make time within a day or two to sit down with my knitting and learn things that we didn't even dream of in the early 80's when my geology professor told me that the western US was so complicated that we really had no idea what was going on out there.
Thank you both for this show! Somehow, it was this little absolute plate motion animation that hit me like an exotic terrane (if I may). That "turn" of North America from a NW to a SW-ish movement, while the Kula and Farallon plates did probably not change their absolute vector really much, should be an important factor. One should be able to figure out (somehow??) when the North American motion was around perpendicular to the Kula plate motion (which would be the time when the faults at/near the plate boundary changed from left to right-lateral, no?). 😳
It continued to be a little garbled but plenty understood, not too bad. Maybe the big wind over Washington. So much better than my driving in rush hour Seattle that you could be speaking Portuguese and I would be happy. Basil always sounds totally normal, so isolated to Ellensberg
Nick, I have been watching your presentations for several years and it has been a great ride. This was a great show and I have a question. Wouldn't it make sense for the terrains getting stuck in the collision and tearing bits off and rotating them as the terrain continues northward, like a ball bearing? Just a thought.
Having spent a year living and working in the McCall area and more years living in Idaho I am intensely interested in the shear zone there. Are there ways to virtually visit outcrops or such that I could see features indicative of it? Perhaps I should look at geological maps of the area. I think I will do that. Thank you both for this.
💖 Super fringe ❣😃 Another great show ❣ I was thinking back to Brian Mahoney saying there's no evidence in the Sierra's for INS or IMS being that far south, but I thought I remembered Darryl Cowan saying something about Tethyan fossils in CA and finally found where Darryl said that... in Eocene F at about 1 hr 9 min to 1 hr 10+ min into it, Darryl quickly / briefly mentioned basalt with exotic Tethyan fossils Klamath mountains and western Sierras. 🤔 Wouldn't that be a piece of evidence suggesting that terrane with Tethyan fossils was that far south? 🤨 Could the detrital zircons from Baltica suggest contact with Alexander with Wales affinity? 😲The waterskiing zombie whale that gets it's plankton from Idaho and has a connection with Wales affinity 😳 🥴 I like that Basil is willing to say his model may be wrong and Darryl too 💞 without being defensive and seeming offended by it. It says a lot. I don't think I will ever have a good understanding of paleomag, but I also don't think I'll ever have a good understanding of technology or how nuclear weapons are made or how nuclear power plants work or a lot of other things (long list); but it still works without my understanding it. What I do understand is that the earth is more powerful than some realize or care to admit. It minimizes sense of control. Trying to control the weather (cloud seeding) is one thing, but trying to control plate movements is easier if one believes they already don't move much 🤪 It's crazy that nuclear weapons were being tested and used before plate tectonics was accepted 🤯 😲 That's nutso! Looking forward to the next show 🥳
@24:30 Something was there that had to be contended with, it just can’t be dismissed like it’s a ship pulling into port. The only explanation to contend with the “void” would be that it was oceanic crust consumed down a subduction zone, in front of the Insular Complex advance into Idaho. I can see why this gets skipped over, it’s a stick in the spokes. Edit statement: An Eastward subduction zone at the “Idaho Trench” would also presumably result in a Cascadia-like arc. Is there evidence of that arc?
Data is always correct. It may however be reinterpreted. The validity of a model is determined by how well it accounts for the data; by how little of the data must be dropped to fit the model. The model must be altered to fit the data, not the data selected to fit the model.
Hi Jackie - I love your phrasing. I something use this quote from Sherlock Holmes speaking in Sir Arthur Conan Doyle's "Scandal in Bohemia": "It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts."
I guess this was a two beer session! LOL something clicked for me today! I feel like the student on Third Rock From The Sun who never seems to get anything that John Lithgow was talking about. John Cleese shows up and changes one term on the huge equations on the chalkboard and the student exclaims, "My God, I finally get it" Nick, I mean no disparagement here. You're a fine teacher and most the time I follow what's going on but this Baja-BC has been bending my brain and Basil made it all click.
It seems to me that if the insular was the force that raised the Rockies with a strike to the craton of N/A, could it have been possible for the insular to have hit N/A first, then slid north before the IM hit N/A?
My uncles are in seattle and tenino, im fascinated about the most current info on the cascadia "big one" earthquake..is there any new info or deep sea tech to help evaluate the jdfuca or cascasdia subduction 2023-2050 prediction/risk indicators?
Is anyone discussing the fact that plutons are like buoys floating up through the heavy ocean 1:49:33 sandstones? Exhuming them rapidly by being set loose from the mantle by a subducting slab.
I love these presentations. I think I mightve watched the exotic terranes video at least a half dozen times. And the others almost as many times. I may not be pursuing a degree in any geology field but it's great to see this information being shared. It's always an interesting topic or set of topics to get into.

Funny watching people work so hard at being helpful and detailed when the reality was the sound quality wasn't bad at any time but just a little different and when you figure in how people's ears, systems etc vary a bit it was never really an issue. Just over diligence by nick fans trying to out fan everyone else. Nick just has to take it in as a whole and not worry about 20% being picky and another 20% being off a bit. Great show though. As always.
When data doesn't fit the model it's not the data's problem. A fundamental scientific principle too often ignored by those who are in love with their model.
If the whale approaches the craton with it's mouth open, can it get caught on a hook (jagged coast of the continent)? Then the craton continues it's feed into the open mouth, causing the lower jaw to push south, as the tale continues to propel the main body north. Eventually the lower jaw is flexed away from the hook and releases the catch to move with the rest of the whale. Hope the jaw didn't come off!

Basil always rocks it. He makes complicated issues clear. Bassil also does not hesitate to say what he thinks and why. Thanks, Nick for providing all this learning.
Basil is just great. I always like what he presents and how he presents!
Great conversation! Appreciated Basil's notes about how the scientific process works: "Follow the data!" Keep it up! (Don't stress about the audio.)
Beautiful show. While I am not a geologist this approach with N. America drifting south, multiple ocean plates in movement, lost faults and a rugged coast line makes sense to me.
@Nick Zentner you have inspired the public to learn about your field of science and engaged people in the process of learning, evaluating hypothesis and constructing an understanding of the world. Congratulations on becoming the world most prolific teacher of science!!!

Oh I wish I thought to have the video running at Lowes to show the power of leverage by expansion. They cut open a bundle of bags of insulation so I could get one and when the strap was cut it pushed a very heavy pallet of material about a foot across the floor.

So be dumb... cause that just means there is so much exciting information for you to learn... learning is fun! Love how you approach info! You dont know it all and you love to learn. Best way to approach anything!
We can hear both of you great. Topic is new to me and fascinating thank you
Thank you and your guest.
More please.
Happy New Year Too All !!!!
46:23 Welcome to the Basil Tikoff Show.. 🤣 brilliant episode, triumph through adversity!
Good show. Glad to be back. Happy new year everyone!
Tikoff's amazing. I backed him up 3 times during this tape to make sure I heard right and understood. WOW@!
Thank you for your most interesting enjoyable articles nd informative videos. Audio good here. Probably just bad weather

One should be able to figure out (somehow??) when the North American motion was around perpendicular to the Kula plate motion (which would be the time when the faults at/near the plate boundary changed from left to right-lateral, no?). 😳
Could listen to Basil / Nick dialogue for hours…
It continued to be a little garbled but plenty understood, not too bad. Maybe the big wind over Washington. So much better than my driving in rush hour Seattle that you could be speaking Portuguese and I would be happy. Basil always sounds totally normal, so isolated to Ellensberg
Good morning from Visalia ca
Nick, I have been watching your presentations for several years and it has been a great ride. This was a great show and I have a question. Wouldn't it make sense for the terrains getting stuck in the collision and tearing bits off and rotating them as the terrain continues northward, like a ball bearing? Just a thought.
Happy New Year, Nick! Thank you to both you and Basil.
Having spent a year living and working in the McCall area and more years living in Idaho I am intensely interested in the shear zone there. Are there ways to virtually visit outcrops or such that I could see features indicative of it? Perhaps I should look at geological maps of the area. I think I will do that. Thank you both for this.
Hi. There are a couple of field trips guides that would help you. You can contact me directly for them - just shoot me an email.
Basil is awesome! “The data is less uncertain than the model!” Basil Tikoff
💖 Super fringe ❣😃 Another great show ❣
I was thinking back to Brian Mahoney saying there's no evidence in the Sierra's for INS or IMS being that far south, but I thought I remembered Darryl Cowan saying something about Tethyan fossils in CA and finally found where Darryl said that... in Eocene F at about 1 hr 9 min to 1 hr 10+ min into it, Darryl quickly / briefly mentioned basalt with exotic Tethyan fossils Klamath mountains and western Sierras. 🤔 Wouldn't that be a piece of evidence suggesting that terrane with Tethyan fossils was that far south? 🤨 Could the detrital zircons from Baltica suggest contact with Alexander with Wales affinity?
😲The waterskiing zombie whale that gets it's plankton from Idaho and has a connection with Wales affinity 😳 🥴
I like that Basil is willing to say his model may be wrong and Darryl too 💞 without being defensive and seeming offended by it. It says a lot.
I don't think I will ever have a good understanding of paleomag, but I also don't think I'll ever have a good understanding of technology or how nuclear weapons are made or how nuclear power plants work or a lot of other things (long list); but it still works without my understanding it. What I do understand is that the earth is more powerful than some realize or care to admit. It minimizes sense of control. Trying to control the weather (cloud seeding) is one thing, but trying to control plate movements is easier if one believes they already don't move much 🤪
It's crazy that nuclear weapons were being tested and used before plate tectonics was accepted 🤯 😲 That's nutso!
Looking forward to the next show 🥳
@24:30 Something was there that had to be contended with, it just can’t be dismissed like it’s a ship pulling into port. The only explanation to contend with the “void” would be that it was oceanic crust consumed down a subduction zone, in front of the Insular Complex advance into Idaho. I can see why this gets skipped over, it’s a stick in the spokes.
Edit statement: An Eastward subduction zone at the “Idaho Trench” would also presumably result in a Cascadia-like arc. Is there evidence of that arc?
How do I donate minerals? I got some really cool specimens from the olympic national forest in the buckhorn area! I really want to donate them
Data is always correct. It may however be reinterpreted. The validity of a model is determined by how well it accounts for the data; by how little of the data must be dropped to fit the model. The model must be altered to fit the data, not the data selected to fit the model.
Hi Jackie - I love your phrasing. I something use this quote from Sherlock Holmes speaking in Sir Arthur Conan Doyle's "Scandal in Bohemia": "It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts."
@@btikoff3707 I always preferred, "He uses data like a drunkard uses a lamppost. For support rather than illumination."
I guess this was a two beer session! LOL something clicked for me today!
I feel like the student on Third Rock From The Sun who never seems to get anything that John Lithgow was talking about. John Cleese shows up and changes one term on the huge equations on the chalkboard and the student exclaims, "My God, I finally get it"
Nick, I mean no disparagement here. You're a fine teacher and most the time I follow what's going on but this Baja-BC has been bending my brain and Basil made it all click.
It seems to me that if the insular was the force that raised the Rockies with a strike to the craton of N/A, could it have been possible for the insular to have hit N/A first, then slid north before the IM hit N/A?
your new yellow line mimics the Juan De Fuca plate?
Second mike was better. Great talk Nick and Basil
GNEISS JUST STARTING TO WATCH.
My uncles are in seattle and tenino, im fascinated about the most current info on the cascadia "big one" earthquake..is there any new info or deep sea tech to help evaluate the jdfuca or cascasdia subduction 2023-2050 prediction/risk indicators?
Just got a moment with the generator running between storms, I'll have a lot of catching up to do when the power comes back!......
R.I.P. Jim Mattinson, one of the U-Pb dating pioneers.
Is anyone discussing the fact that plutons are like buoys floating up through the heavy ocean 1:49:33 sandstones? Exhuming them rapidly by being set loose from the mantle by a subducting slab.
Good ol' Grellow 😊
I love these presentations. I think I mightve watched the exotic terranes video at least a half dozen times.
And the others almost as many times. I may not be pursuing a degree in any geology field but it's great to see this information being shared. It's always an interesting topic or set of topics to get into.
===Another SERIES of QUESTIONS ;
IF YOU WERE TO CHANGE THE "MAP PROJECTION" OF FIGURE 4.
WHAT PROJECTION WOULD YOU CHANGE IT TO FOR BETTER REPRESENTATION ?
??? HOW WOULD THAT LOOK IN COMPARISON TO FIGURE 3 ??? *if performed on this as well, re- map projection change.
> Now, INCORPORATE & INCLUDE SIGLOCH TOMOGRAPHIC DATA BELOW <
??? ARE THERE OTHER DEPICTING THE MIRROR EFFECT ??? ; between ,
item 1) Figure 6: LAURENTIA
\\and//
item 2) SUBDUCTION OF JAUN DE FUCA PLATE | PACIFIC PLATE *present day.
Note (focusing in on)- ?rifts? & transform faulting of both items.
! "spreading" vectors generally; 1) SW , 2) SE , not to be confused with "subduction" vectors.
! ? SOURCE OF SINISTRAL MOTIONS ? !
REFERENCE FIG 4 ; ??? GREATER DEGREE OF LATTITUDE SEPERATION ??? b/t NAm Vs. plotted paleomagnetic means (box + whiskers) in CONTRAST OF PART (A), and, for (B) plots = ??on the MARGIN?? {"Insular - *fossil " ??already landed?? }
or/ is the " *fossil " reference to Tethys Fossils
note- TOMOGRAPHY
WHY CAN WE ONLY GUESSTIMATE LONGITUDINAL MOVEMENT ?
ARE THERE NO MODELS (at present) TO MEASURE THIS • THESE REFERENCE FRAMES ( in the Longitudinal Form ) ?
? ONLY BY WAY OF TOMOGRAPHIC RECONSTRUCTIONS CURRENTLY ?
note-
===QUESTIONS [END]
sweet
The audio wasn’t you. It was Solar wind, or flares, or Russians. Connection/internet related.
Potentially North Korea.. idk though
Also don’t ban me. I’m just kidding.
😎
Funny watching people work so hard at being helpful and detailed when the reality was the sound quality wasn't bad at any time but just a little different and when you figure in how people's ears, systems etc vary a bit it was never really an issue. Just over diligence by nick fans trying to out fan everyone else. Nick just has to take it in as a whole and not worry about 20% being picky and another 20% being off a bit. Great show though. As always.
When data doesn't fit the model it's not the data's problem.
A fundamental scientific principle too often ignored by those who are in love with their model.
If the whale approaches the craton with it's mouth open, can it get caught on a hook (jagged coast of the continent)? Then the craton continues it's feed into the open mouth, causing the lower jaw to push south, as the tale continues to propel the main body north.
Eventually the lower jaw is flexed away from the hook and releases the catch to move with the rest of the whale. Hope the jaw didn't come off!
I think Basil has it right.
Livesteaming, man, amirite? ✌
Not quite done finishing viewing IN-REPLAY, but want to get this out there @NICKZENTNER before heading off to work.
( LAST 10hr SHIFT BEFORE VACATION ).
PERSONAL THOUGHT ( Initial Conjecture ). ! WHERE IS THE BBC FAULT ! *Wrong overall : APPROACH ANGLE ! , Not CROSSSECTION ( 0:29:09 | 1:49:33 ), but CONVERT this to MAPVIEW. ( note- outboard southern ends of Faults | (sutures) | SHEAR ZONES < END MORE NORTHERLY OF INBOARD COUNTERPARTS > etc ... etc ... *Layers of an ONION translating north.
INSULAR RACE CAR TEAM ; TEAM A) *inboard , TEAM B) *outboard
( note- previous comments in previous shows regarding RACE CARS ) : DRAFTING UP THE COAST !
PERSONAL THOUGHT ( Initial Conjecture ). !!! STAIR STEPPING TERRANES !!! [ Figure 11. ] *localized contraction sites @ ; "Orofino" , and where hits between SNszs | SPMsz. ??? DO REMINANTS GET "PINCHED OFF" AT TIME OF TRANSLATION ??? ( @85 Ma , there after )
? OTHER LOCALIZATION SITES ; PUGET SOUND ? *MT STUART ( whale tail )
( note- previous comment in COMMENTS SECTION of previous show : L. Mojave - BC ... with Kirsten Sauer and Stacia Gordon )
KEEP THROWING THE HEAT !!!
'until next time
ps- WHAT ROCKS ARE YOU SIPPING ON IN THE MUG OF HOT WATER ?
