My first one on TH-cam. I downloaded all of them before I watched them so no comments from this graphic designer (aka, geology geek). This was wonderful, Nick. Jeff Tepper was a great addition and we learned some new things today. Those of us who are NOT "official" geologists grow smarter by the day, thanks to you and your guests :) And we love YOU too!
Great show. You almost scare the s+++ out of me when you walk to the edge as you are breathing so hard. Take care of yourself Nick as we love you too!! Mary
Wow!!! What awesome, awesome views. Washington is such a beautiful state. Everywhere you go there is something to see and learn. Thank you Professor Zentner for taking the time to put all of this together for us who do not live in Washington. Take care, stay safe and God bless.
The guest star appearances are good. Not to dis you, after all I was able to piece out your exchange on "CRB's" from what I've picked up from your videos. Thanks
That was fantastic! I feel like I was part of the research in the field! It was great to hear how the rocks are dated and researched. Thanks for the show!!!
Thank you so much, Jeff and Nick. That was fantastic; really interesting to see a little bit of how geologists approach work in the field, and the scenery was the icing on the cake.

Thanks Nick! Beautiful day to be hiking with Jeff and talking about rocks! Lovely views, Oh My... Love that country!
I enjoyed the hell out of this one! For ME it was one of the BEST you have done. I like seeing "how it is done" and learning about technologies and techniques. Man this was so cool in that regards. Thank you thank you thank you.
Love it! Fascinating to see what to look for, how much quantity different analysis processes require, But, Nick, you are killing me with walking up so close to those cliffs! Hah!
Gorgeous country - especially from the flatlands of Minneapolis. It doesn't take much talk of chemistry to overwhelm my minimal understanding, but enjoyed the discussion of evaluation techniques.
Love the field trips! It is wonderful to follow expert geologists, watch their techniques and have a front row seat to the conversation. I would like to learn more about zircon dating and have more specifics on their formation and crystalline structure.
It was great to learn more about how the samples are analyzed. Perhaps we can follow some samples through analysis and see the sample prep and test equipment sometime?
Thank you for teaching us about Peoh Point! We've been wondering how it fits in to the geologic story of that area for years. Jeff's a total pro. He didn't miss a beat when you giggled at "cleavage". 😆 His class sounds interesting, too.
I really expected to see one of you look at the other with wide open eyes , saying " Wow , what do you make of that ? " No such luck , but enjoyed it much. Thanks to both of you.
I'm still at work (keeping health care professionals stocked with working keyboards and mice), and upper management has decided to have a meeting at 1430 local time until 1500. Hope they get finished in time for me to catch this live, otherwise I'll have to watch it later.
I wonder has anyone studied the lavas between meneral Washington and Vail I am really enjoying today's field trip looking forward to hearing about what you learn thanks.
The slant in that terrain is crazy is that andosite pushed up like that? (I may have asked this too early if you answer it in the video just didnt wanna forget) if indeed it is thats the coolest view of it ive seen of "uplift"? Would you call it? Beautiful beautiful terrain thouh either way.
"at end of the semester students who haven't budgeted their time well find it a bit stressful." WHAT?? Say it isn't so! Great stuff Nick. Truly makes this retired geologist from the Illinois Basin envious of having real outcrops and rocks of interest (other than the pancake stratigraphy of the Paleozoic) at one's front door. Talk of thin sections takes me wayyy... wayyy back and seeing the GPS location technique makes me feel real, real old. Oh well. Keep up the good work during this Covid-crazed time.
The panoramas into the valley at 2:55 and 6:14 are breathtaking! Very interesting. As an aside, I am reminded of Frank Zappa singing about zircon-encrusted tweezers. Greg in TN
Nick can you teach the whole west coast..california has three old volcanoes that long gone. but the one near Sacramento wore down to almost nuttin..the foot print 10 to 12 miles wide..sutter brutes..
Yay! UPS! That is where I went to college. Can you ask Jeff if he remembers the funny geology teacher at UPS in the late 60's? Wow - what a view! Are Zircons in both sedimentary and igneous rocks? And what is it in Zircons that makes it able to do dating? You guys must not be afraid of heights!
I'm not Jeff but I'll be happy to try and answer. Zircons are crystals of the mineral ZrSiO4 - zirconium silicate and are incredibly resistant to weathering effects and therefore almost always unaltered since they formed in the magma. Thus they are in both igneous and sedimentary rocks (apart from those of biologic origins) but will only date the igneous rocks precisely. Zircons are excellent for dating as the crystals readily incorporates uranium in their makeup and captures that uranium in an unchanging crystal i.e. you can be quite certain that the amount of uranium plus it's decay product you measure matches the amount when the zircon crystal formed. Uranium decays, and through several steps, end up as lead. So to get a date, you just have to measure the ratio between the uranium and lead found in the crystal and compare it to the half-life of uranium. An example: U238 has a half-life of 4.47 billion years. If your zircons have 99% U remaining and 1% has decayed to Pb, the age of the zircons is close to 65 million years. Uranium has more isotopes than U238, so that will modify the result a bit, but not by much. A bigger concern is how you get the concentrations of U and Pb. A small inaccuracy will have a big impact on the date when your half-life is in the billion year range. From what Jeff said, you can now get that uncertainty down to something like 100.000 years on a 100 million year scale and that I find impressive.
*ZIRCONS:* Trapping that uranium at the beginning, counting that lead at the end. *TIP:* Cubic zirconium usually doesn't impress a potential spouse with its measly 8.5 on the mohs scale; they will be looking for that 10.
They are as if pebbles in the mid Pacific.... metiorites hit at " terminal volicety". 440 mph to 214 mph.. not generally hard enough to bury themselves even in sand or a plowed field...few are big as basketball s..very few larger...for large ones see az. Crater....best example in the world.
Thanks NZ lotsa love from Wellington NZ

What a fantastic "field trip class" this was, and what spectacular scenery!!! Thank you Nick and Jeff!
A a 3
Great to re-watch this after seeing Jeff in GEOL351#31! Thanks Nick and Jeff!
Professors Thank you for the continued learning about washington state geology. Much Appreciated.!
Absolute magic Nick ,thanks to you and Jeff ,from UK.
Great show. You almost scare the s+++ out of me when you walk to the edge as you are breathing so hard. Take care of yourself Nick as we love you too!! Mary
All was interesting but learning a little about dating was marvelous. Scenery was superb. Thanks for another great experience
I really like the way Jeff uses his blacksmiths single jack on the rocks . Outstanding application and effect.
Wow!!! What awesome, awesome views. Washington is such a beautiful state. Everywhere you go there is something to see and learn. Thank you
Professor Zentner for taking the time to put all of this together for us who do not live in Washington. Take care, stay safe and God bless.
come for the rocks stay for the landscape
excellent. Thanks Mr. Zentner
I'm really enjoying the Nick on the Fly series. This one was especially interesting, learning about the zircons and dating. Fascinating.
Excellent field trip. Your video quality was great!
Well, one my place I want to go to.Thanks Nick and Jeff.
another stellar presentation.
Nick you could call your last 2 episodes "Nick On The Edge" taking us to some great overlooks
Very informative, thanks!
Hey nick! I just camped at potholes state park and was lucky to know about the Othello basalts thanks to you! Please keep up the videos :)
Love the look into field work and the lab work that will follow. Very interesting!
Another great learning episode! Thank you Nick and Jeff!
Very much enjoyed that Nick! Thank you.
Outstanding is as usual an understatement. Thank Professor Tepper for us!
Such a great Educator
Thanks Nick!
This was wonderfully informative. I really enjoyed this Nick & Jeff. Thank you!
I missed the live stream...but always enjoy seeing your videos, Profesor.
I really liked this Nick. Learned so much about the collection process. I would like to see more like this.
Been there a number of times. Now I know more. Thanks.
The guest star appearances are good. Not to dis you, after all I was able to piece out your exchange on "CRB's" from what I've picked up from your videos. Thanks
Again, it’s great to see you out and about, Nick, beautiful area and hope all is well with your family!
Hit THUMBS UP for Nick!!!
That was fantastic! I feel like I was part of the research in the field! It was great to hear how the rocks are dated and researched. Thanks for the show!!!

Thanks Nick! Beautiful day to be hiking with Jeff and talking about rocks! Lovely views, Oh My... Love that country!
View was incredible and material was very interesting. This was your best video yet.
10:50 "Fairly unhappy." Anthropomorphizing JUST a tad there....😂
Great scenery and information, greatly appreciate your videos. Question, CRB?, that building on the point, sort of relay, repeater station?
To be in your hip pocket has been elucidate ing! Appreciate you both!
unhappy rock.. lol ..don't know anything about geology, but sure is a nice hike! ty~
Thanks, Nick. Enjoyed the views as much as the geology! Looking forward to the next adventure:-)
.cool video keep up the great content

Thanks fellas 👏🏼
Wish I could listen live, will look forward to the replay.
Only a geologist would date an ugly rock. Another great video, by the way. Big concepts in a brief presentation. You deserve accolades by the ton.
It was great to learn more about how the samples are analyzed. Perhaps we can follow some samples through analysis and see the sample prep and test equipment sometime?

Now that is a geological hammer ... !

Fan. Tas. Tic. show! I love these informative short shows. It's amazing what can be accomplished with a $500k production budget, right? (🤣🤣)
I wonder has anyone studied the lavas between meneral Washington and Vail I am really enjoying today's field trip looking forward to hearing about what you learn thanks.

Beautiful beautiful terrain thouh either way.
Just fyi: andesite
Hey Nick, I'm back to listening to the podcast.
I'm ready and waiting
"at end of the semester students who haven't budgeted their time well find it a bit stressful." WHAT?? Say it isn't so! Great stuff Nick.

Hey Nick, just spent the night just outside your town last night. Now in Randle Washington
Thanks Nick! Hard to hear Jeff sometimes however.
Interesting show Nick. I missed you live unfortunately. Also, I need to get a more persuasive hammer.
Did Jeff find a happy sample during that outing? How many Geologist are lost a year walking off a cliff?
Most of them. That's why we need to keep training more!
Those rocks were minding their own business for about 50 million years. Little did they know a couple geologists would have other plans for them. 🔨🤔
Very nice view 👍
At 22:59, that cinderblock comms building used to be the base of the Peoh Point fire lookout: www.firelookout.com/wa/peoh.html
Nick can you teach the whole west coast..california has three old volcanoes that long gone. but the one near Sacramento wore down to almost nuttin..the foot print 10 to 12 miles wide..sutter brutes..
Vertigo....vertigo....VERTIGO!!!
what are the structures at 4.10?
Nick Dating the Zircons helps solve the Baja BC. theory Right?

@@gamarus0kragh Wow! What a fantastic and detailed explanation! Thanks so much!

*TIP:* Cubic zirconium usually doesn't impress a potential spouse with its measly 8.5 on the mohs scale; they will be looking for that 10.
Some spouses don't give a hoot at all. I have worn a stainless steel band for 35 years and totally happy with the lack of moHs.
@@stacywestly64 Yours (mine as well) is measured on the Rockwell Hardness scale lol
Now that's science!
Dibs, I"m here for the long run.
I'll be slogging away at the hospital , but you'll be the first I watch when I get back at 3pm.
Kamikaze Kurt bless you for that
Waiting... sigh...
17 hours. Almost there !
949; Jeff makes a valid sacrifice of the chosen one . ..unhappy... One sample for the zircon godz :l.Pp20...analized an thin sections ahoy!
🙏
Has anybody ever studied the kinetic input of energy earth gets from meteor impacts on our lithosphere?

The zircons are too small to encrust my tweezers.
My Pygmy Pony has left my barn.
Hope we get the answer before the beer runs out.
It mite be you could look for memory in the crystal they do have memory.
Be careful out there! During this pandemic time 2 people have died (fallen) up there.
