Thank you for doing this again, awakenedsediment! Avana was right...I can copy and paste your time stamps into the show description above and YT then shows the chapters in replay at bottom of screen. Very cool. If you have time, could you please go back to Session A and edit your time stamps with an added 0:00 Video Starts? I can then do the same with A. Thank you!
So very kind Clint-Coat to Coast. World needs more people like you and Nick! Tom and Cindy do you know Bill and Sally H. from Hyampom? Small world! Nick, you must understand your gift. You make Geology real. That is your gift and your style of communicating is why we all are here. You are a gifted man.
I think the names of the events should reflect the ages such as “event” 50, “event” 100, and “event” 170. The repetition will help associate the events with the age.
ok am readintg the chat responses to Nick's request for new names for the "main events". Was laughing by the boxcar/locomative option, but totally lost it at the stooges.....
On that diagram of the oceanic plateau as they docked, were so thick that the back half snapped the crust behind the plateau, opened a spreading ridge to form another oceanic plateau, the strike slips being formed by North American oblique movement. The drop and stop of the ocean crust subduction making waves for the orogeny that is formed by these waves of basalt crashing into North America continent…
I did not get to join the live show at 2pm, but just finished watching it now. What a great 2nd episode Nick! I can tell most everyone really enjoyed it, as did you. I am very interested in how the west coast was built (I live on Wrangellia) so keep them coming!
These are created in Honor to Nick Zentner, our favorite Geologist. Shows perhaps what he does in his supposedly “off” time. *(Ha ..what is that He asks..)* See Nick at Home A-Z A = Series Set Up Hopefully more to foollow.

The Scotland mention was interesting. I remember thinking last year that tarraine relates to Europe in general. Which brings me to Avalonia and the forming of the UK, Northern Europe and the Eastern North American seaboard. It is all very complicated!!!!
When I was taking a history course at Dalhousie University in Halifax, NS, the teacher emphasized a number of techniques to make essays more effective. One was to have a series of sentences in decreasing length. 5, 4, 3, or 4, 3, 2, or the unbeatable 3, 2,1 series. That makes the west coast powerful writing ... IMT has three; INS two; Siletzia! Love the dock-and-slice explanation for 351!
I'm really late to this one, but in the line of thought of connecting dots - Is the plume that possibly created the oceanic basalt plateaus the same that then 'moved under' the northwest and is now actually known as the Yellowstone plume?
Nick caught the stream late but saw it all and enjoyed it. Something we share is a Midwest Geology connection in that I got my Geo Eng degree at Mn. I did other things in my career and started to get back to Geology with your 101 class last year. I recently bought the road side geology books for MN and Wisc. And was surprised that the geology of the northern part of the two states is so similar to what you teach for the western NA. It is almost as if northern MN is the Precambrian erosion product of the cascades. No one taught this to me in 1981 it was all glaciers. thanks ! now I put 2 things together and yes it is fun
Nick's videos got me more interested in geology too. So much so that I drove my wife to Ellensberg in September. We visited Vantage, the Lahar west of town...the Palouse area...looked for blue agates and found some at the jewlery store in town....(Nick should get a commission on that sale). Then I saw the Roadside geology book for Mn. Drove down to St. Thomas University to see the volcanic ash between the limestone and sandstone. Never knew our area was so close to a driftless area just east of us.
@@mmmh2o5 funny how I spent hours looking at those rocks and never knew that layer existed. My education was lacking in certain geological areas. Best wishes to you
I'm playing catch-up on these, so at this point I'm four letters behind. I've got some of the old recording of the pre-COVID lectures saved to show my mother, who, after a major stroke some years ago, now lives in a nursing care home. I loved those old lectures, and as Mum has similar interests to me, has visited Oregon and has friends living there, she will too... if she can stay awake long enough to watch one all the way through! I'm guessing all the 'names' for events and so on have been sorted out, but I thought I'd have my say anyway. The terranes coming in always reminded me more of books or films being released, than gumdrops sticking on. This seems even more apt now with the superterranes being made up of two or more terranes that accreted out in the ocean before colliding with north America. For me they'll be Book1 170Mya, Book 2 100 Mya, and Book 3 50Mya. And the individual terranes in ech will be volumes in each Book!
Here's some food for thought: I was watching your "Nick At Home: Flood Basalts" and people were wondering what caused the fissures and why they emitted basalt, an oceanic lava. I noticed that the fissures are close to the edge of the North American craton. What if a superterrane (ironically an oceanic plateau that is 3 miles tall or thick) hit North America 170Ma, then began being pushed by NA moving SW? That would put stress on the superterrane, perhaps causing cracks and fissures, or at least weakening it. Then when the Hot Spot passed by, there was a ready made weakness in the crust made mainly out of basalt? I just couldn't help but notice that the fissures are beside the edge of the NA craton. Just a thought from an insomniac. PS: Lava runs downhill. In the Nick From Home video, you stressed the terrain around the flood basalt and how we can't know what's under the flood basalt. Is it possible where it's 3 miles deep, that it was a valley or big hole? It's impossible (as far as I know) to know the topography before the flood basalts started. I understand the weight of the food basalt pressing down, but it's possible it was filling up a hole, too. I know I usually think outside the box, but this has some logic to it, it seems to me. Be well. Greg :)
Thank you for this episode, Nick! So sorry I missed it live... when winter threatens, my yard prep beckons. I've been thinking about names for the parade of terranes and the three main events. Here's my "terrane" of thought: Parade... floats... giant floating balloons... giant floating super-hero balloons; which all led me to: As super-terranes, maybe each group could be named after DC super-heroes... in order of appearance. Well known characters, easy to remember: Superman Group 170 (Superman, introduced 1938), Batman Group 100 (Batman introduced, 1939), and Catwoman Group 50 (Catwoman introduced 1940). The Flash was also introduced in 1940, but I thought the ladies in the house, and that Bad Boy Bijou, all deserved a nod :) Thanks again, for all you effort and dedication, Nick... it is so very much appreciated, and by so very many!
Might be called smoosh and smear, as docking is usually considered soft, but smoosh includes a good impact, compression and deformation on the impact line. Slicing is usually thought as a clean break, while smearing also brings up the terrane deformation and tension. From the pieces with Erin Donaughy, it sounds like there was a combination of compression and tension faults throughout the region, and these words contain hints at it. Smoosh and Smear
Another visual aid might be a blob of playdoh being smooshed and then smeared on a block of plasticine, representing terranes and old NA respectively. 3D deformation and impact affects both, but deforms the softer terranes easier than the old. Old cracks and splits, while the young would plastically deform and spaghettify.
Excited for the third. Hoping to apply the things I learn here and get a better understanding of.......everything lol. Great content, thanks for doing this for us.
Cache creek as in between nespelem and keller on the Colville rez? I noticed kettle falls so am assuming lol. Im from keller and work on the keller ferry and after watching your video of dating the ice age floods i was hooked
Last year, I went to the bookstore on the day I was in your class. There were none available but one of the workers went into the office and found one! So I got lucky. And this winter, I am going to go through all of my notes and redo them and follow along in the yellow book.
Thanks, Nick! Did I miss it or have you not discussed what makes the terranes adhere, or stick once they arrive? And at what speed are we talking...over what time period before they stay in place...and...are major faults located along the margins of these terranes? Did "docking" cause folding in the craton margin...due to the collision?
Second idea I had, on your "dock & slice" is to use 3 kinds of cheese - semi soft, like lumps of Brie, Mozzarella that hold their form until they have pressure & heat - then as the "slice" happens, they sort of smear north along the NA continent.
from your first A-Z, i remember that the INS accreted with westward subduction of NA plate.. (pardon me if i am wrong) so if that is the case, i am thinking that the wrangalia docked at some place north of the north america. so the Alaska blob is the docking location. Am i right?
I wonder if today's Point Reyes peninsula (sitting on the Pacific Plate) in central CA is a "sliced" part of an exotic terrane that docked somewhere in Mexico or SoCal a while ago.
Oh, I missed live again. So, just want to report, that iam still watching your lectures, but i did not catch you live for a while. But you still do a great work (and still better and better). I count myself as one you opened eyes about beauty of geology with your early public lectures... and still going on :-) greetings and thanks from Bohemia
With all this generosity, I wonder if the many many Zentnerds have considered endowing a scholarship for some fund-deficient promising Geology student(s) or some such in honor of Nick.
I was buds for a short time with son of geologist yorath sorry first name I forgot. He has an excellent if a little dated explanation of Vancouver island terrane, we got about 7 or 8 here alone. Nick where waitin.
This is so fun; I'm a little late to the party but trying to follow along with an old Alt & Hyndman "Roadside Geology of Oregon". I notice you trying to hold back as the story begins to outrun the data, and the storyteller tries to be a disciplined scientist, probably being pushed by the impatient general audience. Tension!
Oh, I am having a blast here, Nick! Sitting on the edge of my chair and loving every second of it. I cannot wait for the rest of the alphabet to air. Thank you so much again for putting it all together for us, professor! Warm greetings from Dreischor in The Netherlands to you and your loved ones and to all those who are watching. [edit] About the 'naming of the few' (paraphrasing Shakespeare): Not every Tom, Dick and Harry (hint, hint) may understand Hewey, Louey and Dewey (Donald Duck's nephews); Nick, Liz and Bijou come to mind ; The first three presidents of the US of A (but not quite known all over the world); How about 'the Intermontane', 'the Insular' and 'Siletzia' ? Clear to anyone following the series which event is meant. I guess I'd go with that. But I will be happy with whatever names you choose. 😊👍 [end edit]
Thank you Nick from the Kalama gap. According to PANGA headed north toward Friday Harbor at 16 mm. Per year. I will be in Burlington, WA soon at that speed. Ha Ha. Thank you for geological maps that I would never see without your presentations.
Document camera might be a good way to redo prop motion for IMS, INS, Sil accretion as it allows several materials to be lumped together and migrated at once while also allowing static positioning and time to talk/explain between relative positions. If you feel comfortable with doc cam eventually, and Incase you want to drive the super group point home in a tangible way. Great session today! Dock and slice really works for me! Another Fantastic visualization phrase!
If going East to west (and from oldest 170 Ma to 100 Ma ) these could be a 1-2 punch. Right Cross for the IMT event, and Left Hook for the INS. Helps me to remember the geographic relationship on the map.
The names reflecting the first cited kixRUIBA like Cambrian and PreCambrian give it more of a dash of the exotic while relating to local features, like Cash Creek, IMHO.
How about main events reflecting an epic movie trilogy...like main event #1, 170m yrs ago is "Star Wars: A New Hope"... the hope that starts to create our amazing pacific northwest! "Empire Strikes Back" for the 100m event because DAMN that's the best movie, just like wrangellia is the greatest exotic terrain responsible for the Stewart Range and the jaw dropping Enchantments! And the 3rd event 50m yr ago Siletzia is "Return of the Jedi" because it created the Olympics which is a straight up Endor-looking rain forest..always expect to see Ewoks around every corner every time I hike there. Love these lectures man! You do amazing work.
Ocean plateaus , source, yellow stone hot spot? You had shown previously the hot spot has had the north american plate moving over it. Maybe out into the Pacific? Thank you for your efforts.
the stick built truck under the parade float/clown car is the basalt, the bells and whistles go off when the float plows into the garage wall obliquely and parts bounce off and skip on up the parking garage wall.
Main Events could be "generically" called Big Events, as this implies multiple events, and just use IMS, INS, Siletzia to clarify, or interchangeable with 170ma,100ma,50ma or even IMS170, INS100, Sil50 Big Events. Alternatively, go back to First Act, Second Act, Third Act for shorthand.
Your analogy is that of a series of train wrecks. Trains made up of multiple cars that are assembled elsewhere and scatter all over the place after the collision. Your train names are Insular, Intermontain and Seltzia.
When the basalt flows in the atmosphere on (mostly) dry land, it is German chocolate cake. When it flows underwater on a shaky, twisty, jerky tectonic plate, it is upside down cake. When the latter dries out and hits continental mass, it gets sliced into stale, toasted croutons that are sprinkled on the craton. Cratons, croutons, craters, and cracks - it never ends. All the while wind and water grind it into grains of sand.
How about the pie-in-face gag...Intermontane triple-layer mud pie, followed the Insular two-layer lemon meringue pie, followed by the Siletzian marine chocolate cake.
I inadvertently left a question on session A, about session B. I will ask again. Would figure 26 of Kerr's 2014 paper. Be how Wrangellia or other additions to old NA, an example of a Bubble the below surface. Coming colliding??
Some people I know thought you should have recognized the emergency in BC. I argue that this video is timeless or at least takes place millions of years ago. Future people who watch this in 5 years or more won't care about what was going on the day of the recording. People have lost their lives and some are still in danger as I write this now, for the record. I don't know why I'm recording these thoughts here, but hey here we are.
I recall something about one of the main events being a volcanic arc shaped like an "L" prior to docking, and that explains why they are worm shaped now. Is that no longer accurate?
Nick: If you're watching in replay you can scrub ahead.
Me: No. No I don't think I will.
haha love the check ins and pre lecture chat
I think that is some of the most interesting part of the program.
I've never skipped them either 😄
I love the pre-lecture chats too. I feel like I’ve made a lot of new really interesting friends.
Mo, Shep & Curly !
I like the Dock, slice and dice!
I missed following these live, I think N was released today. But gonna watch the replays to catch up before i join live.
Nick- You are a legend and are the best show on youtube. I love the way you connect the dots and explore this history. Please do not ever stop!
2/13/22... Just started this series! You've made this a favorite local geologic subject for this listener! I'm on for the series, thanks for your efforts!

Thank you for doing this again, awakenedsediment! Avana was right...I can copy and paste your time stamps into the show description above and YT then shows the chapters in replay at bottom of screen. Very cool. If you have time, could you please go back to Session A and edit your time stamps with an added 0:00 Video Starts? I can then do the same with A. Thank you!
This is just perfect. Thank you from England.
This is so helpful going back to catch up. Thank you for taking the time to do this👌
I am here as a nostalgia for the chuck board :)
So very kind Clint-Coat to Coast. World needs more people like you and Nick! Tom and Cindy do you know Bill and Sally H. from Hyampom? Small world! Nick, you must understand your gift. You make Geology real. That is your gift and your style of communicating is why we all are here. You are a gifted man.
I like the idea of helping our memory with your repetitions :THE 170-INSULAR docking, the 100-wrangellia docking and the 50 Selezia docking
Is it Dock and Slice or Slice and Dock
Great show, Nick! Hello to you and all Zentnerds! I like the cows on the railroad track idea.
At 7:15 that's way-cool what Clint from Coast to Coast did. That's very generous.
I think the names of the events should reflect the ages such as “event” 50, “event” 100, and “event” 170. The repetition will help associate the events with the age.
Email this to him.
Looking forward to Saturday’s video.
Thanks for telling us where to find previous sessions.
ok am readintg the chat responses to Nick's request for new names for the "main events". Was laughing by the boxcar/locomative option, but totally lost it at the stooges.....
Yeay! More geology from the Nick Zentner. Always a good day for geology.
Thank you for your time and energy.
Saturday should be fun. 🎉
beautiful bolo tie
Another fantastic talk sir.
Thanks for a very stimulating class. I'm trying to get caught up. Happy new year
Thank you for connecting the dots, very interesting Nick.
I love it how you take all the parts, like a puzzle, and put them together.
Nick: It’s going to go quick!
UA-cam: Dramatic pause…….
Me: confused?
Love being in school again!
On that diagram of the oceanic plateau as they docked, were so thick that the back half snapped the crust behind the plateau, opened a spreading ridge to form another oceanic plateau, the strike slips being formed by North American oblique movement.
The drop and stop of the ocean crust subduction making waves for the orogeny that is formed by these waves of basalt crashing into North America continent…
I think everybody should have to do a shot every time he says
"Sorry Patric" lol
I did not get to join the live show at 2pm, but just finished watching it now. What a great 2nd episode Nick! I can tell most everyone really enjoyed it, as did you. I am very interested in how the west coast was built (I live on Wrangellia) so keep them coming!
These are created in Honor to Nick Zentner, our favorite Geologist.
Shows perhaps what he does in his supposedly “off” time.
*(Ha ..what is that He asks..)*
See Nick at Home A-Z A = Series Set Up
Hopefully more to foollow.

There are also a few other terranes glued to Vancouver island, my house is on lime stone.
The Scotland mention was interesting. I remember thinking last year that tarraine relates to Europe in general. Which brings me to Avalonia and the forming of the UK, Northern Europe and the Eastern North American seaboard. It is all very complicated!!!!
Finishing up watching at 03:01 Thursday and it was worth it.
Great lectures, thanks.
When I was taking a history course at Dalhousie University in Halifax, NS, the teacher emphasized a number of techniques to make essays more effective. One was to have a series of sentences in decreasing length. 5, 4, 3, or 4, 3, 2, or the unbeatable 3, 2,1 series. That makes the west coast powerful writing ... IMT has three; INS two; Siletzia!
Love the dock-and-slice explanation for 351!
I'm really late to this one, but in the line of thought of connecting dots - Is the plume that possibly created the oceanic basalt plateaus the same that then 'moved under' the northwest and is now actually known as the Yellowstone plume?
A terrane wreck?
In that case the Pacific Northwest has had three giant derailments.
Nick caught the stream late but saw it all and enjoyed it. Something we share is a Midwest Geology connection in that I got my Geo Eng degree at Mn.

We like the replays since the timing is not good for us to watch live.
I'm playing catch-up on these, so at this point I'm four letters behind. I've got some of the old recording of the pre-COVID lectures saved to show my mother, who, after a major stroke some years ago, now lives in a nursing care home.

Are the flood basalts too thick to core into in order to see what is buried beneath them?
Thank you for this episode, Nick! So sorry I missed it live... when winter threatens, my yard prep beckons.

Please check Dan Hurd. He has something called a blue picture stone bright blue, white and clay like red-brown he is in south western Canada
Second idea I had, on your "dock & slice" is to use 3 kinds of cheese - semi soft, like lumps of Brie, Mozzarella that hold their form until they have pressure & heat - then as the "slice" happens, they sort of smear north along the NA continent.
"76 trombones lead the big parade!" Next I think it's 110 cornets.
from your first A-Z, i remember that the INS accreted with westward subduction of NA plate.. (pardon me if i am wrong) so if that is the case, i am thinking that the wrangalia docked at some place north of the north america. so the Alaska blob is the docking location.
Am i right?
due to time zones I won't be joining the live streams but i hope to follow along through replays
I wonder if today's Point Reyes peninsula (sitting on the Pacific Plate) in central CA is a "sliced" part of an exotic terrane that docked somewhere in Mexico or SoCal a while ago.
That is near where I live
6 miles inland ...
good question
Wish we had a Nick for California geology
With the ice shelf collapsing causing the wave that will bring basalt out of the ocean onto the surface .
Act 1,2, and three of the slice and dice murder mystery theater
Oh, I missed live again. So, just want to report, that iam still watching your lectures, but i did not catch you live for a while. But you still do a great work (and still better and better). I count myself as one you opened eyes about beauty of geology with your early public lectures... and still going on :-) greetings and thanks from Bohemia
With all this generosity, I wonder if the many many Zentnerds have considered endowing a scholarship for some fund-deficient promising Geology student(s) or some such in honor of Nick.
You should do a Kickstarter or something out of that idea. There are plenty of us here. 😊👍🏻
Since there is an Oceanic Plate "enbedded" in each of the events, why don't you name the event by the OP enbedded?
I was buds for a short time with son of geologist yorath sorry first name I forgot. He has an excellent if a little dated explanation of Vancouver island terrane, we got about 7 or 8 here alone. Nick where waitin.
Could you mention a good current textbook(s)?
This is so fun; I'm a little late to the party but trying to follow along with an old Alt & Hyndman "Roadside Geology of Oregon". I notice you trying to hold back as the story begins to outrun the data, and the storyteller tries to be a disciplined scientist, probably being pushed by the impatient general audience. Tension!
Nice Biggs picture jasper.
Thanks for the journey through time. Time lining is critical to figure this out. What collision forces raised the Colorado Plateau?
Oh, I am having a blast here, Nick! Sitting on the edge of my chair and loving every second of it. I cannot wait for the rest of the alphabet to air.
Thank you so much again for putting it all together for us, professor!
Warm greetings from Dreischor in The Netherlands to you and your loved ones and to all those who are watching.
[edit]
About the 'naming of the few' (paraphrasing Shakespeare):
Not every Tom, Dick and Harry (hint, hint) may understand Hewey, Louey and Dewey (Donald Duck's nephews);
Nick, Liz and Bijou come to mind ;
The first three presidents of the US of A (but not quite known all over the world);
How about 'the Intermontane', 'the Insular' and 'Siletzia' ? Clear to anyone following the series which event is meant. I guess I'd go with that.
But I will be happy with whatever names you choose. 😊👍
[end edit]
Greetings from Zierikzee..
Thank you Nick from the Kalama gap. According to PANGA headed north toward Friday Harbor at 16 mm. Per year. I will be in Burlington, WA soon at that speed. Ha Ha. Thank you for geological maps that I would never see without your presentations.
Document camera might be a good way to redo prop motion for IMS, INS, Sil accretion as it allows several materials to be lumped together and migrated at once while also allowing static positioning and time to talk/explain between relative positions.
If you feel comfortable with doc cam eventually, and Incase you want to drive the super group point home in a tangible way.
Great session today! Dock and slice really works for me! Another Fantastic visualization phrase!
Wonderfull!! Can't wait for more.....
I was unable to join the live stream but am watching now!
Thank you Clint your awesome also lol
Your new bolo looks like a picture of a subduction. I have Cascadia on the brain.
If going East to west (and from oldest 170 Ma to 100 Ma ) these could be a 1-2 punch. Right Cross for the IMT event, and Left Hook for the INS. Helps me to remember the geographic relationship on the map.
The names reflecting the first cited kixRUIBA like Cambrian and PreCambrian give it more of a dash of the exotic while relating to local features, like Cash Creek, IMHO.
A New Hope- 170ma
Empire Strikes Back-100ma
Return of the Jedi- 50ma
We need to get some palaeomagnetism comparisons to see if your hypothesis of the cache Creek exotic teranne fits into the idea of dock and slice.
How about main events reflecting an epic movie trilogy...like main event #1, 170m yrs ago is "Star Wars: A New Hope"... the hope that starts to create our amazing pacific northwest! "Empire Strikes Back" for the 100m event because DAMN that's the best movie, just like wrangellia is the greatest exotic terrain responsible for the Stewart Range and the jaw dropping Enchantments! And the 3rd event 50m yr ago Siletzia is "Return of the Jedi" because it created the Olympics which is a straight up Endor-looking rain forest..always expect to see Ewoks around every corner every time I hike there. Love these lectures man! You do amazing work.
Ocean plateaus , source, yellow stone hot spot? You had shown previously the hot spot has had the north american plate moving over it. Maybe out into the Pacific? Thank you for your efforts.
the stick built truck under the parade float/clown car is the basalt, the bells and whistles go off when the float plows into the garage wall obliquely and parts bounce off and skip on up the parking garage wall.
Main Events could be "generically" called Big Events, as this implies multiple events, and just use IMS, INS, Siletzia to clarify, or interchangeable with 170ma,100ma,50ma or even IMS170, INS100, Sil50 Big Events.
Alternatively, go back to First Act, Second Act, Third Act for shorthand.
Oh snap I’m across the street from the cache creek terrain right now haha
Wonderful show, More Nick less Tech. Thanks.
Your analogy is that of a series of train wrecks. Trains made up of multiple cars that are assembled elsewhere and scatter all over the place after the collision. Your train names are Insular, Intermontain and Seltzia.
Strike one(Imt), strike two (Ins), strike three (Siletzia).
Dock and slice, or maybe Bump and grind
When the basalt flows in the atmosphere on (mostly) dry land, it is German chocolate cake. When it flows underwater on a shaky, twisty, jerky tectonic plate, it is upside down cake. When the latter dries out and hits continental mass, it gets sliced into stale, toasted croutons that are sprinkled on the craton. Cratons, croutons, craters, and cracks - it never ends. All the while wind and water grind it into grains of sand.
I already want a "Zertnerd" t shirt, ... maybe the back can read "Cratons, croutons, craters, & cracks"
Thanks Professor Nick. Great start. Thank You. The Main Event = The Triple Crown?
How about the pie-in-face gag...Intermontane triple-layer mud pie, followed the Insular two-layer lemon meringue pie, followed by the Siletzian marine chocolate cake.
Names of the three exotic “alien” terrain events …. “Plateau, Barada, Nickto”
I inadvertently left a question on session A, about session B. I will ask again.
Would figure 26 of Kerr's 2014 paper. Be how Wrangellia or other additions to old NA, an example of a Bubble the below surface. Coming colliding??
Big smooth,,, you ROCK!!!
cake 1, cake 2, cake 3
Some people I know thought you should have recognized the emergency in BC. I argue that this video is timeless or at least takes place millions of years ago. Future people who watch this in 5 years or more won't care about what was going on the day of the recording. People have lost their lives and some are still in danger as I write this now, for the record. I don't know why I'm recording these thoughts here, but hey here we are.
I recall something about one of the main events being a volcanic arc shaped like an "L" prior to docking, and that explains why they are worm shaped now. Is that no longer accurate?
In place Main Events would the analogy to a show work? You could use Act one, Act two and so forth.
