Whenever I click the UA-cam icon on my first page of Chrome, it is the first choice offered. I guess because they know I click on it often--- goes up several days early.
For some reason, this is the best episode for me. In the middle of it a lot of things started to make sense - something about the discussion between Chris & Nick & some of the history Chris layed out made a big difference.
What a wonderfully enjoyable episode, yet again. I loved Chris's delightfully matter-of-fact style of presentation. We had yet another "mind blown" moment when he showed the image of a zircon and how they could pick up different aspects of the life history of the grain by scanning areas only a few microns apart! Very impressed at how easily Chris was able to fit his piece of the jigsaw into the puzzle that has been so skilfully assembled over the last 2 - 3 months.
What a great moment when Chris was recounting the work his dad and others did in the early days of zircon dating. The legacy of the workers in the geology of the Northwest has been a recurring theme in many of your interviews (thinking of Cowan, Wells, Beck, Haugerud), so I really heard you when you expressed regret about not being able to include Rowland Tabor in the series. I went back and watched the backyard interview with Ralph Haugerud and gained a new appreciation for this aspect of your work. For me, Geology is history, and the stories of the workers in this field are a valuable part of it.
This is a great series Prof. Nick! Thanks Nick and Chris for keeping the drama going. Thanks to Chris for supplying the history going back to 1955. The presented history of evolving viewpoints and technology over time is great. The flow of knowledge from Geology 101, Geology 351, Exotic Terranes A-Z, and the Spring 2020 series provide a great background to prep for this series. Roadside Geology Series fan for 30+ years. PBS Nova “Making North America” is great but this regional in-depth technical series is even better.
Chris Mattinson is always so lucid in his discussions. Thank you. I have a much better understanding of zircon dating. Nick, a good job on your board layout. That helped me too.
I get a notifacation usually the day before that says "set reminder". so I tap that and i get a notifacation on my phone saying you will be on at such and such time on the day of class.
Thanks for the reminder on the mission/purpose behind these lectures. As a "Geology Noob" I do feel a constant urge to go back and tie everything together to help me conceptualize how it all works. That's probably why I've watched most of your videos at least once. Again thank you to you, your guests and all the people in the live chat who help answer questions. I'm definitely hooked on PNW Geology.
Finally, deep into geochronology tech! Thanks Nick and Chris for sticking it out there. History meets current geo-status. Best interview yet! And the source is right upstairs! astounding lol!!! Very impressed.
I'm recapping lots of these videos for further confirmation of what i have learned from Nicks Channel. Chris is a mind of info and explains that complicated info very well. I suppose that's why he teaches, because he is good at it. A belated thanks for more important and interesting info.
Another great informational experience! I loved hearing about the pioneers in geology, especially Prof.Mattinson's dad! Thanks Prof. Nick and Prof. Mattinson!
Thank you Nick and Chris! I love the way Chris simplifies things making these complex ideas so matter of fact! Watching this series has completely changed my perception of the world around me ! Thank you so much!
Watched from Edmonton Alberta Canada 🇨🇦. Love all the guests makes a armchair enthusiast able to keep up and understand even if we just have a casual interest in it. Can't wait for "Z" lol but love all A-Z episodes so far. Great job Chris and Nick!
I have my iPhones’ alarm set for 1/2 hour prior to classtime, both Weds and Sats. I am a notorious phone ditcher, as i despise having a ball and chain, if you will. But i have to learn this stuff somehow!!
I'm glad you didn't choose my question Nick, I didn't think it through very well; I can only guess that it was my question that didn't make sense to you, or anyone else for that matter. The Paleomag should be very revealing; Wells or Beck, I'll need to bring my paper bag in anticipation of another bout of hyperventilatioin.
Appears that the positive and negative buoyancy of rocks is shifting continuously at least on the geological time scale in dependence of the the mineral content, which in turn is changing through the shifts of plate tectonics or even, through positive and negative feedback loops, influences plate tectonic . Just think of how zinc reduces the melting point of steel when in contact. These synergistic actions between different minerals happen most likely in the earth crust too and it gets quite complicated if you put that factor into the equation. Very much enjoy your presentations and guest speakers!
Haven’t head that idea about buoyancy (density) changing. Sometimes heavy stuff goes up, the forces don’t care. Your mention of the zinc-effect has me wondering if there was a zinc-ish undercoat to or component of the sprayed-on exothermic gel on that wretched NYC day. I too really like Nick’s shows. Especially ones with guests, as he gets so much out of them by his moderation, and really shows appreciation for the best stuff.
More stats: Nick said on 2/5 @ ~1:30 that about 1,000 were watching this. It's now 2/8 and count is 8,553. Eocene P on 1/15 streamed to 900 and now is at 20,121. These Eocene videos may set records for long-form educational video outreach. Congratulations are due.
Dr. Mattinson or: How I Learned to Stop Worrying and Love the Zircon. I'd love it if Chris did an hour or three on the topic and how it applies to PNW geology.
Wow. That first 30 minutes (or 45:) ) just parted the clouds for me. Not that I understand the answers, but the questions you were asking totally tied in all of the previous episodes. Outstanding, and thanks!
GET TO THE SESSION VIA PLAYLISTS AS A EARLY BIRD, BUT WOULD REALLY LIKE TO HAVE A LINK RIGHT AT THE TOP OF SUBSCRIPTIONS OF THE IMPENDING SESSION! SOME DO IT VIA YT PREMIER, OR SCHEDULED VIDEO. IF IT IS A FAVORITE SUBSCRIBED IT STAYS AT THE TOP OF THE LIST, WHICH IS WHAT I WOULD WISH FOR, AS SOMETIMES I AM RUSHING TO GET TO THE MACHINE, FUMBLING TO FIND THE PLAYLIST WORKAROUND.
2/22/22: Dings come to computer only, never by email, but there are so many dings due to other subscriptions, all sounding the same sadly, that one tends to ignore them or sleep thru them. I usually catch after the fact. I mentally try and remember ur reg. days but still miss them. So your consistency of days helps us to remember. Watch only on You-Tube.
The chat comes up early if you go to UA-cam before the session goes live. You have to find the session, and click on it.. At least that's the way it works on PC. It works this way with or without notifications.
52:29 Nick, why can't this be due to slab brake off & rollback? The broken slap would rapidly rise due to isostasy, and the crust would be exposed to much hotter rock from below causing the magmas. It makes perfect sense with westward subduction under a ribbon continent. The trace element geochemistry for slab rollback plutons is compelling, and I have not heard a refutation yet.
Seems like it would be cool, but also seems pretty greedy to wish for. The guy is giving us a TON of his time, effort, and expertise for free as it is.
What the heck is migmatite? I’ve poked around the web but never developed a proper understanding of its development in extant geologic systems. 1:09:50 a moment of elegant clarity with definition and image. I finally get it. Thank goodness. The stuff is all over the Cascades. Or under ‘em. Cut and polished, it would make a badass floor for the front door entry foyer. Or tile a shower stall with it. Look at the beautiful piece Nick is holding here. Wooo!
I have an unrelated question, way unrelated...regarding the Seattle glacial till, would it be like the quick clay in Norway? And, though those are ocean floor clay deposits, would it be a possibility that Seattle could ever experience a landslide like the 1 that, devastated large areas of rural Rissa I mid-Norway in 1978? I understand salt content has a great deal to do with it, so maybe because it has fresh water origin and many misc rocks in it this doesn't even apply. Also, I get you are more of a volcanic rock guy, but as I watched that Seattle video I was curious.
It's a oases unsorted jumble and it can not liquefied like the quick clay. Btw I've watched some documentrys about it. However there was some flooding early on so the city raised the level of the city partly with any trash logs sawdust the could use they also washed down hills with hydrolic mining techniques . Nick did a show about the problems this may cause during earthquakes
@@jeffbybee5207 I think it is much different in composition here than there, the clay there is very smooth, dark, & very little pebbles or clasts, So that may be it. Oso mud slide looked similar but that was in the state of Washington, buried a town not as giant as some of those in Norway. Thanks for the response.
Chris's comment about stopping leaded gas helping precision with analytical methods reminds me that leaded gas is still used in the aviation industry, particularly for older prop planes. I wonder if this has any impact on precision any more.
I'm totally enjoying these Nick but I'm a little overwhelmed. I know you're reluctant to tie this up in a review show. I understand. Maybe make a ZZ show so it doesn't get in the way of your plans. I'm pretty new to all this and trying to keep up but I feel like I need to step back and look at what I've learned. My vote is for a review and clarification show. Maybe I'll feel better after the Z show. Thanks Nick!
Northern Washington is one small portion of North America. Question is, are there a broader contemporaneous issues impinging on the story when viewed in the context of what is going on in the rest of North America and also the rest of the World????
Routes and Rocks is a wonderful work. Used bookstores charge so much I photocopied the UofW library copy, and hand colored my taped-up copies of the maps, adding lines for routes I've followed. Nick, does your copy have the maps? If so, wanna sell?

You're having a warm front at 43 degress. We're having a cold front at 55/38. It's a great thing that climate and weather aren't the same thing!
A masterpiece of inclusion. Thank you Nick and Chris. Thank you zircons.

I watch in the evening 9:42pm
That must have been hella noisy back then. Probably why dinosaurs had no ears, and humans waited until they could hear each other talk.
On the Bell icon, there is a notification that the show will start in 30 minutes.
