Nick visits a rhyolite quarry in the Teanaway Valley. Filmed on August 22, 2021. GPS location for quarry: 47.297722, -120.821472 Mike Eddy's 2015 paper: www.geology.cwu.edu/facstaff/...
In the past this would all have been gibberish to me. Now, I hang on every word and follow along nicely all because of your efforts to share in this media. I have learned much.
I had never even heard of Rhyolite. I had to look it up "Rhyolitic tuff has been extensively used for construction. Obsidian, which is rhyolitic volcanic glass, has been used for tools from prehistoric times to the present day because it can be shaped to an extremely sharp edge. Rhyolitic pumice finds use as an abrasive, in concrete, and as a soil amendment."
Forester: What beautiful Stone ! This banded rock will make a beautiful fireplace. Geologist: Interesting Rhyolite, but this damn banding gets in the way of determining mineralization ! 😂
Man O' Man Nick... I wish you would take a field trip to Walker Creek/Walker Valley ORV area. If you haven't been already... you would be like a kid in a candy store. One of the most geologically diverse areas I've been to in Washington State.
Another comment: thanks to you, Our Professor Zentner, I was actually able to get through some of Mike Eddy’s papers on the Migration of the Triple Junction!!
My Dad was a metalergist with a love for Geology, I became a Chemical Engineer who ended up with a career in the army with a love of Geology. My middle Daughter is a silver smith with a love of Geology. I remember taking walks (drves) when I was young and dad stopping and peering at interesting formations throughout California. I hadn't realized how much I had learned until I took a couple of years of Geology in the early 70's. Alot has changed since then! Really enjoy your channel, keep it going. I was through Mt Lassen, Oregon and Washington just 3 months ago and had inadvertently traveled around to many areas you have talked about. Good job!
Just wanted to say, a friend put me onto your podcast after I told her I started my second degree majoring in applied Geology after working in finance for 10 years, and I’m slowly falling in love with everything geology and your podcast and these videos are so nice to have ❤️
Welcome to the geology family, Alex. Once I retired from being a pathologist, I got hooked on geology and Nick Zentner's livestreams. You will love your new path!! Nick did his livestreaming of the exotic terranes last winter and he had a huge following - we would all talk to each other on the chat. Those bi-weekly sessions helped all of us get through that Covid winter, an I still have my notes and refer to them at times. Geology is absolutely fascinating - with its many, many facets. So, again, welcome!!! Lorraine
I have to say that I am not a geologist, I study EE, but this guy's ability to generally describe what he theorizes without claiming "absolute truths" has turned me onto geology immensely.
It is not a Forest Service Road, it is part of the Teanaway Community Forest and belongs to DNR. The rock was used by a private timber company that owned the 52,000 acres the DNR bought in 2013. The timber companies used it to make their roads. DNR has also used it since they purchased the land, it is on the new Lick Creek road. If you continue on up Middle Creek you will find more outcroppings of it that are in road cuts.
We live in a trachyandesite quarry in the dead Otago voclano, New Zealand, and these rocks are their twins, right down to the banding, circular forms, the brittle fracturing, the clasts etc. Our rock was used for railway foundations and some building.
My dear Professor! Your videos capture my curiosity about our beautiful Cascades and surrounding environs! Camping at Kachess and exploring the Teanaway basalt s on the east ridges also. I've got the bug!
Nick I really enjoy your geology studies and lectures! I am an engineer with the UnionPacific in Spokane,I’ve always been intrigued by the Missoula Flood. Your lectures have inspired a growing interest in geology. My runs north and south from Spokane take me from Eastport I’d. to Hermiston Ore. Basically traveling 90% of the flood path! I can keep myself alert on those long days studying the passing geology! Thanks for the inspiration!
You ain't 25 no more. I used to love navigating unstable talus. So much fun, and descending these things, balancing on the mini-landslides, was good down-hill skiing practice. I think, even at age 72, I might like to try it again sometime. Except I ain't 25 no more.
Thanks for this video. The feldspars are weathered to kaolin. It'a a kaolinization that brings the very light color. The limonitization that forms ocher concentric rings has a special name: These are Liesegang rings which are often in sandstones. If the basalt is over it and younger and it's from the same source you have much working forces in the underground. First the emplacement of the homogeneous rhyolite, then the explosive tuff which opens at a weakened zone and in this weakened zone the basalt could take place. Is it magmatic underplating? Is it magma mingling? If the basalt is from another source you have other possible emplacement mechanisms. Rhyolite is a beautiful rock.
@@volcanismgemsandgeorisks4982 I was poking fun at your very informative post, but I was seriously impressed with it. I think your name: Volcanism and Georisks...explains a lot about your interests. Geology will always find a way to throw something different and odd and out of place at us, won't it. That is what makes geology so fascinating and never dull.
im fascinated by the cool quarry near cool california if you ever get a chance to make a video of the history and would be an honor to meet you.thank you
Thanks Nick! I even Took the scientific paper and added some notes on! Can’t describe the feeling as a kind of « magic » one that cheers up each time, there is something special ! Love you dear professor ! Glad to follow and thanks for sharing all as you do!
I'm watching this with my cinnamon roll and coffee. When you showed us that first "cinnamon roll" rock, it made my day. I love your walks and how we can "skooch our bottoms" down the slope with you.
Some of those smooth round cobble rocks you were standing near towards the end of the video looked very suspicious. I wonder if there is an ancient streambed there.
I just bought one of those hammers! Your edu-ventures always teach me how I can ask questions and investigate the nature of rock and features in my own region so I can explore its geological stories here. There's always something to take away and use to expand on, even being reminded to look for any documents, maps or charts publicly available about our own areas.
Plenty of basalt around Like the pit ECP has on the lookout Or even look at peoh point This is a good one Nick Short and sweet And coincidentally If you can get way west of that quarry Like almost behind cle elum There's quite and interesting formation Not so much banded like what you've got here
I LOVE these walks with you just as much as all your other videos!! I feel like I'm right out there with you enjoying your company and geology. Can never thank you enough!!
There is a videographer of the volcano in Iceland. Roman shows the same interest in the lava as Nick does but Roman is not a geologist. He’s noted the different lava expelled from the volcano. These two could have a lot to talk about if they met I think. His videos are on TH-cam under the name of Gutn Tog.
I've been following the TH-cam video on the Iceland valcano. GutnTog has been filming there from the beginning in March. From what I've learned watching Nick's videos I find I understand better what I'm seeing in Iceland even though the mechanics are fastly different than Washington state valcanos.
I’d like to know a bit of the history of the quarry. Who developed the quarry and why? How old is the excavated quarry? Is there any (archaeological) evidence that the rhyolite was used by people that predate modern use?
So very interesting. Thanks Nick, for a truly mysterious piece of the geology of central Washington. Best of all it's presented as a leisurely walk in the woods! #gooutside
Love your Spence of humor Nick! That’s Rhyolite? Well, Gee! I have seen that in Eastern Oregon while my dad.and brothers went fishing and mother and I walked and collected stuff. I didn’t pay attention to this at all.
Isn't a "huh? That's strange" the reason we keep doing what we do? So many questions in this world that remain unanswered and waiting to be found. Thanks for all you do from the Green River Gorge.
I am sooooo happy you are making a channel!! Been watching your geology chats for years. Amateur explorer of nature geology in the PNW. Spent a lot of time in the endless bush of the Caribou for years. Glaciation is amazing. Crazy depositions. Anyways I'm so happy and wish you the best! Will keep watching thank you!
Thank you , everything about the paper’s just mesmerizing. The student’s work is a miracle just the SCALE of geological time and the sheer SIZE of these places are confounding lol! anything can happen eek! Super)
Mike Eddy Paper, Table 1: Sample NC-MPE-418 is ~3.3 miles NW of Sample NC-MPE-417A (in video). Just past Twentynine Pines Campground take 1st left onto NF-9701, then left on 1st Spur almost to end. See middle of left-hand column on page 432 for an explanation of these 2 Samples: "In an attempt to date...".
Thanks so much for letting us follow you on this walk, Nick. I've ripped the seat out of more than one pair of pants on slopes like that - hope you had some spares in the car :D Looking forward to updates on this formation.
Thanks, Nick. Always enjoy your treks in the field. It’s still so blasted hot down here in SoCal. It’s kept me from spending time in the field exploring our complex geology. Nice to hear that your weather was enjoyable:-)
Thank you for taking us along on another interesting field trip trip. Be careful on that talus slope. I also use the rear end technique when all else fails. A few scratches and bruises are always better than a broken leg etc
There seems to be a variation in the types of lava that come out of various of those Cascades mountains...I'd say underground trolls are swapping the magma plumbing around from time to time to confound geologists.
In the past this would all have been gibberish to me. Now, I hang on every word and follow along nicely all because of your efforts to share in this media. I have learned much.

A gneiss little walk in the good weather.
In the Carolinas in the Piedmont there is Rhyolite that the indigenous people used that chipped like Chert. Also a Welded Tuff that worked the same.
Noticing river cobbles at your feet there at the end of the video.
Thank you Nick for taking us townies on your walk. I'm grateful it wasn't my butt sliding down on those sharp rocks.

It's very satisfying to see those rocks smashed open. :-)
The inside of the rocks looks like the rings of a tree. Very cool video. Keep em coming. 👍🏻👍🏻

“Breath through your nose?” Thanks for the lovely fireplace backstory.

I was doing some gold prospecting in the volcanic field near Yuma, AZ area and picked up a very interesting pink rock. I believe it is rhyolite.

Enjoy your talks very illuminating for people who want to learn
Enjoyed it as I have been for many years! Hope that you will do a follow up on these rather mysterious rhyolites and explain their story, thanks!

Love you too 🤗 You silly ole Scootcher
And thanks!
Interesting, as usual, even when much of it is far over my head. Thanks, for taking us along, Professor…

I forgot to add. I am none the wiser but, I am getting to appreciate you enjoy doing that to those of us, 'who are easily confused'.
I found Creek worn pieces all the way down by mineral springs camp ground. Thank you for clarifying what it is and where it came from.👍🐍
Careful on those slopes Nick, leave it to experts like me. Expert rock licker and taker of dangerous paths
As always excellent! Thanks Nick 🙏💜
Thanks it’s always fun to be in the field with you!
Thank you for the clip
I would love to build a fire place with that banded beauty! Thanks for letting us tag along!!!!
Some of those smooth round cobble rocks you were standing near towards the end of the video looked very suspicious. I wonder if there is an ancient streambed there.

Short and sweet
And coincidentally
If you can get way west of that quarry
Like almost behind cle elum
There's quite and interesting formation
Not so much banded like what you've got here

Thank you Nick. I always enjoy your videos.
Excellent. Close up of rocks really effective - informative. You're helping me to learn to read hand specimens better.
I'm still enjoying all your podcasts, even if I'm not catching them live anymore. Stay safe!
Love your Spence of humor Nick!
That’s Rhyolite? Well, Gee! I have seen that in Eastern Oregon while my dad.and brothers went fishing and mother and I walked and collected stuff. I didn’t pay attention to this at all.
Quary
There’s some of that stuff coming out at the top of the Chelan Falls road.
Thanks, Nick (B. Barto here) for taking us along. This is really interesting.
So there was subduction zone volcanism happening there 24-26 million years ago? What else was happening at that time and where was the continent?
Thanks for posting.
Isn't a "huh? That's strange" the reason we keep doing what we do? So many questions in this world that remain unanswered and waiting to be found. Thanks for all you do from the Green River Gorge.
Thanks Nick. Just got back from Colville. Check it out some time.
There is white rock on a mountain top area in eastern Washington along the Columbia River area. Wonder what it could be? It covers a lot of area.
wow!!! I sure miss you!! forest service roads are nice... okay going to listen.., will check back in, 😊😉🙂
Yet another site I've been to many years ago. I wish I knew then what Nick is teaching me now.
This summer we collected this Rhyolite material in the middle of the Idaho Batholith. Beautiful rock but certainly out of place for its surroundings!
So did the Royal light come from mexico?
Are there agates in that area of the teanaway?
Plus or minus 14,000 years?!?! That's incredible!!!
Sean Bowen I was wondering what that decimal number meant in years but too lazy to do the math...lol...so thanks..!!
@@marbleman52
😂 Sure
Leftover fracture from Teanaway formation it appears. Cascade Volcanics started popping off…the pressure got released there.
Also love the tinkling sounds from the wind!
Hi Nick. Love your stuff. Never a dull moment.

Cool! Another bit of info to add to our 351 data.....thanks for another informative hike and some more questions to ponder..... 🙂
Hi there, there's a quarry up here in easton wa with very similar rock.
Your videos always leave more curious. I just love the geology around here.
Mysteries is bread and butter for curious mind.
Refreshing to have truth seeking acivity in nature.
Way to go!
47 ma with 24ma side by side!
Nick, I CANNOT get enough of this stuff! I am so hooked on Teanaway!
You fall down cliffs very gracefully professor!

Enjoyable .... The banding looks like Liesegang rings.
Thanks, Nick. Always enjoy your treks in the field. It’s still so blasted hot down here in SoCal. It’s kept me from spending time in the field exploring our complex geology. Nice to hear that your weather was enjoyable:-)
Nick negotiating the talus slope = Pure gold
A mystery. Love your video Nick . It is so fun to be in that gizmo on an outing with you!
My first question would be how the dating method works and can that be skewed.
A real joy before bed here in SoCal- thanks Nick!
Thank you for taking us along on another interesting field trip trip. Be careful on that talus slope. I also use the rear end technique when all else fails. A few scratches and bruises are always better than a broken leg etc
Love what you do. Wonder if that beautifully banded material would take a polish, it’s a fine gemstone if it’s hard enough.
There is a rhyolite quarry in adams county Pennsylvania that was used by the native Americans
I think I saw some rhyolite on my hike today in Revelstoke National Park (British Columbia)!
There seems to be a variation in the types of lava that come out of various of those Cascades mountains...I'd say underground trolls are swapping the magma plumbing around from time to time to confound geologists.
Absolutely amazingly informative.
Way to show us your stuff.
Huh-!
