That was an excellent presentation. There are a number of online sources that provide the facts of geology. Yours is one of them. But there are not many that teach the concepts of geology and analysis of the facts. You do that. Geological understanding requires not only knowledge of three spatial dimensions, but of geological time. This series is providing a basis for that. I hope I will be able to keep up. 😎
Today's episode of Cascades A to z brought to you by "Ugly Russel Ranch" 🤢 I loved the ugly bit nick! Hopefully the others were just joking when they said they were offended. This was a great and informative episode and loved the ending. Super excited for Episode D on Thursday!
I am in aw about how deep you are going with these rocks. I never knew they were even there. I love how these geologists are tuning in to learn and be a part of this too. You are opening a door into the Cascades, and for education in general that wasn't there. If it was, I never knew about it. Any of it!!! Thank you Professor for opening my eyes.
This is great. We, as your students, have benefited from your action as a science communicator. Now we can see how much you enjoy that role between professionals as well. I, too, deeply appreciate the fact that professionals are commonly in the live chat.
Nick, I am awed at the sheer amount of time you put in each and every installment of the A to Z series (past, present and most probably future). First there are the preparations: subject, which parts, which excerpts from former videos and emails, which maps, etcetera, and then mixing all that in a presentable melange. Then there's the video itself. But then, post presentation there is the review and reading of reactions, both of the live stream and of the later viewers like me and also emails of peers and viewers! How do you do it? I am really amazed. So thank you for all your hard work! Love from Dreischor in The Netherlands. ❤
The Garrison Keiller of geology: very soothing to listen to and very enlightening. It's like Prairie Home Companion but with volcanic eruptions and occasional orogenies.
Missed this last month. Watching December 15. Fascinating how the seemingly stable earth under our feet twists, turns and churns tipsy Topsy over the eons. And what happens when that threatened mega quake occurs here some day between today and the next hundred years? I'm in Kent, Washington and the side of East Hill has slip fault cliff only a short distances from where I live. Downtown Kent is in a valley created by that subduction. When?
I'm in the middle of that now. But ugly is there. It may contain the remnants of a collision and facts the investigators require to piece together what happened.
The colors for the 'decades' are easy for me to remember. Gray is easy for 'old' and grellow is famous now, but also easy to remember since Jamie is from the sunshine state 🌞 which is well known for it's citrus 🍊 (orange for the 50's) and has plenty of 💧water 🌊 around it (blue for the 40's). Red is Christmasy (on the 25th) for the 20's and green is also Christmasy, green is between (in the 30's). The teens being German Chocolate cake, brown & yellow (brellow?)🤔 is a piece of cake to remember. 🥮🍰🤪😝🤣 And purple is fresh / new
Hi Nick! Love your videos. I recently had the lucky opportunity to fly over Craters of The Moon! If you haven't seen it from the air yet, you should. Its very cool and I thought of your talks the entire time! Thanks for bringing Craters to life for me!
Great grad seminar! I wish my grad seminars had been so tight and questioning. If they had been I might have even stuck with the academic side of geology. Oh, and the Russell Ranch piece was fantastic! I want more of this!
When did the Russell Ranch the "Ugly Gellow" start uplifting? Did it uplifted because of the Siletzia accretion?? Or, did it uplifted more recently within 10...20 million years in the form of eruptions from ghost volcanos?? Very interesting!! The Ugly Gellow might be the key to uncovering the mystery and its geological history... Ugly Gellow wants to come alive, Nick!! 😆Fun, thanks, Nick the story teller!!💞🩷✨
I loved the Epilogue of Russle Ranch and my question 🙋♂️ is - - is what was Below Russle Ranch and what pushed him back up though the surface? Another Question is I see the 101 models showing the transitions from magma and crust but I kinda wonder 💭if what we see in the surface isn’t a inverted XRay or the Substrate Crust??? The answer to everything is looking you (me) (I) (we) it’s looking us right in the face if we would just look at it… 😊
Thanks Nick great episode! Sorry I had to dip out halfway through the live to get to my snow tire appointment. Man, I was starting to feel really bad for Russell Ranch LOL. 😂I will poke around a bit and see if I can find the name origin. UPDATE: See below for place name origin for the "Russell" geographical and presumptively geological desigination. I doubt Israel Russell, but then again you never know. Keep in mind Bretz was studying the southern Washington volcanics in the area, including Mt Adams and Mt Hood and the Columbia Gorge, before he got sidetracked by those pesky floods. Somehow I had missed placing Burch Mountain on my mental timeline, and now I am pondering the fact that it is apparently millions of years younger than the CRB that is lapping at its feet. I have to go have a big think about that, which will no doubt keep me busy until Saturday. Russell Ranch formation most likely named after the John Russell ranch in Yakima County which gave it's name to Russell Ridge and Russell Creek. "This creek rises on the southern slopes of Russell Ridge in western Yakima County and flows south to join the north fork of the Tieton River. The Tieton reservoir now covers the site of the John Russell Ranch which was once on the north side of the river."
Siletzia is the culprit!! It forms out on top of the Yellowstone Hotspot…So big it sits on the crust making a a depression…now the melange belt is in front of is being pushed up…so Siletzia is pushing the whole mess forward…while diving deep under the sandstone as it enters a trench …on the back of the melange belt…the straight creek fault is a fault that was where the subduction of the farralon plate which became a strike slip fault…the Olympic Wallowa Linament seems to be the east west strike slip that defines the separation of the melange belt…the intrusion of Siletzia slid under all of the Basement rock that got uplifted including the Crystaline Core…The Russel Ranch is the sawdust!!!!
Theory: the WMB was a subducted forearc basin that didn't get very deep before it returned to the surface (under thrusting older units in the accretionary wedge to the east). This was a fast subduction area (see also: flat slab). Fast subduction means hotter, so it dried out quicker and involved more hydrothermic actions closer to the subduction line. This is why it came back up with so little metamorphosis - it didn't get as deep - and was 'blended' by the hydrothemics. This predated Cascade volcanics, which began when water got further down. It could also be caused by heat from a hot, subducting siletz crust.
Question about the origins of the Western Melange Belt. If it began as a late Cretaceous accretionary wedge, is it's present position due to being displaced, then thrust eastward by the arrival of Siletzia? If so, can we draw any assumptions about how far south it may extend? Likewise, is there a correlation between the pre-Siletzia trench and the Straight Creek Fault?
The Siletz Terrane origin may indeed be grey as well; consider it formed on a spreading ridge, with aging and subsidence toward the Eastern margins. The colder, denser, thinner Siletz Eastern margin wasn’t thick and buoyant enough to have survived subduction and therefore, no evidence of it has been found. Ponder that.🤔
13:58 Wow. Multiple cameras, monitors, keyboards and a tight network. Boy have you grown as a technically astute presenter. I've been watching since "the backyard", ladder and fruitcake/pizza boxes days.
Sooo hate to double comment but the last 4 min of the program you entertained the idea of Selitiza having a bull nose sub surface feature. Up to this point it has been implied the face as it starts the impact into the Continental Plate can different sub elevations have say a 10,000 year or million year Delta for impact and is this a continuous impact?? Could this be a fragmented impact of say 50,000 years of drift or a delta of drifts at elevations as it makes contact with the contenintal Plate? Can they scroll and layer like a Ding Dong at the Magma Layer thowing off the dating process??? Love it to All who contribute to these Videos and Nick does a good job putting the bow on top! 😊😊😊
Interesting side thought: This is why there is gold in them there hills, e.g. Liberty. Black smokers, i.e. hydrothermal vents in off shore settings which are swept up in the WMB, concentrate metals, possibly with help from primitive forms of life. They then get broken down and the gold incorporated into quartz veins, which are further hydrothermal events caused by cascade plutonism. Can the quartz veins be dated like zircons are?
Caught the second half of the live. Liked most but not the berating an ugly student gag. It might be funny but for the fact that many professors get off on abusing students and are allowed to get away with it.
I agree. The skit at 1:16:30 sure succeeds in being a memorable joke to embed the name Russell Ranch into students’ minds. But it’s humor is based on meanness. It punches down, not up. And it implicitly condones judging people by how they appear, and of faculty doing that to undergrads no less. Ouch. I wish you had revised the joke so that it wasn’t about a student but something inanimate, like a sculpture of something. I’m a long time fan and in awe of your skills in teaching, and I know putting out these videos at such a rapid rate doesn’t allow much time for editing and revising. If fact, that’s part of why you are so appealing, you present as informal, authentic, off the cuff, improvisational, and good hearted. So I think mistakes like this are bound to happen, don’t really know what to suggest. I just felt I should say something as it triggered bad memories. - Scott in Salem, Oregon

I was talking to a friend once about how ugly the evaporite rocks around here are. Later I realized she thought I was talking about her town and not the rocks,
Nick - try enabling Concepts in UA-cam studio. UA-cam will automatically pick up technical words and define them under the video. Some of your vids from 2 or 3 years have that on and it’s helpful for the 101 people.

Could the WMB be "regurgitated" subducted Siletzia? What caused the upset tummy, getting gut-punched by the unsubductable Siletz Terrane LIP and/or the associated Slab Break/Gap/Rollback?
These series are Awesome/Amazing🎉 now i am thinking in the date of the rock that Sir Jamie found, 3,3 Billion...in the Mélange Belt...how the rock got there, where is the origin of the rock 🤔...could be from Canada?...by a Ice sheet? 😅
Ok first of all the Russell Ranch reverse pep talk... I'm dying 🤣🤣🤣🤣🤣🤣 Well done. 🤣🤣 Second, another fantastic episode in the books, Nick! The email from Jeff Tepper had so many great nuggets in it that I had to pause and read it a few times.

LOL! Ugly Russell Ranch! If you discover subduction, east or west, you are going to get a melange belt of accretionary wedge in between. There must be a Melange belt buried to the west of the Sierra Nevada Batholith in CA that is perhaps an older extension of the Russell Ranch stuff? But you would think it would have made itself obvious adjacent to the El Capitan and Half Dome plutons.
I'm a day late, but don't think the scientific method really applies to what you're doing. "Washington's Story", geologically. Like you're putting a movie/story together from 2 dozen screenwriters providing a scene each. You're assembling it into a logic, time, plausible, historically factual product that meets the observed landscape of today. The story is less foggy, sometimes surprise and WT heck!? The best part , like learning of Harland Bretz; the journey and people we meet, is the best part.
Watched again tonight to get back up to speed! Looking forward to you resuming the programs. Thank you for your great videos - fun and educational!
Interesting and educational. I think Washington state goes to the top of my 'bucket list'. And tell the cat that I said 'Pssst,pssst,pssst.
Just finished Marcia’s book Timefulness and it was compelling and thought provoking. I’ve ordered her newest book too. Many thanks Nick!

@@hopsgegangen2575 top comment!! So true haha
I’m just a rock hound , I like watching you
I am enjoying this series very much. Watching from the Mae Sai basin and range, in Thailand. I do miss the chalkboards though. :)
I had to re wind a lot, but sure do love thise videos. I agree not all rocks are pretty, yes some are ugly.
45:00 The process You are described is one of synthesis, of forming a hypothesis and it is beautiful !:-)
You had me rolling on the Russell Ranch, I know it was endearing of how significant it really is.
yes, please make a video showing the crushing, sieving, and especially the zircon concentrator!!
I would enjoy seeing that too
Missed this last month. Watching December 15.
Fascinating how the seemingly stable earth under our feet twists, turns and churns tipsy Topsy over the eons.
And what happens when that threatened mega quake occurs here some day between today and the next hundred years?
I'm in Kent, Washington and the side of East Hill has slip fault cliff only a short distances from where I live.
Downtown Kent is in a valley created by that subduction.
When?
I feel bad for Russell now haha 😄 😅😂
I'm in the middle of that now. But ugly is there. It may contain the remnants of a collision and facts the investigators require to piece together what happened.
I get the impression that Nick is not a big fan of those aesthetics.
Poor Russell, so abused.
I had an older cousin named Russell.
The Russel Ranch rant was so great❣❣ I loved it❣❣ Being an ugly person, I was not offended
Geology isn't supposed to make me cry! 😥😢😥😢
What heartfelt words from Marcia.
1:20:45+ I love it when you venture into the "Lunatic Fringe." Welcome!😃
Love your map too Neck
Missed the livestream, but made it to the replay! Thank you Nick from Mount Vernon Washington!

Sorry I missed the live, I will watch the video 😊
Gary - Love that late '60s Honda Trail 90!
Thank you for confirming that Grello is not a callback to Cache Creek. I was watching old Terrane videos to jog my memory.
Hey Nick. You gave Russell Ranch a real dressing-down. His salad days are over. 😅

I thought that the Russell Ranch thing was funny.
Russell is indomitable! Nothing can keep him down!

Does the Silver Star pluton in the south Washington Cascades come up through the melange belt?

I haven’t hiked up Mt. Si since I was 12 years old in 1968. Boring hike. Now I have a reason to return to look for the gabbro!
The Siletz Terrane origin may indeed be grey as well; consider it formed on a spreading ridge, with aging and subsidence toward the Eastern margins. The colder, denser, thinner Siletz Eastern margin wasn’t thick and buoyant enough to have survived subduction and therefore, no evidence of it has been found. Ponder that.🤔

Good afternoon from UW.
Im 3rd shift guy so I get the Wed session for my breakfast time 😁 Shoutout to Bijou for the help
Me too!
13:58 Wow. Multiple cameras, monitors, keyboards and a tight network. Boy have you grown as a technically astute presenter. I've been watching since "the backyard", ladder and fruitcake/pizza boxes days.
You suffix "Russel Ranch" with "ugly" so automatically that I feel.obliged to bring a block of it home and carve something ravishing in it.
Sooo hate to double comment but the last 4 min of the program you entertained the idea of Selitiza having a bull nose sub surface feature. Up to this point it has been implied the face as it starts the impact into the Continental Plate can different sub elevations have say a 10,000 year or million year Delta for impact and is this a continuous impact?? Could this be a fragmented impact of say 50,000 years of drift or a delta of drifts at elevations as it makes contact with the contenintal Plate? Can they scroll and layer like a Ding Dong at the Magma Layer thowing off the dating process??? Love it to All who contribute to these Videos and Nick does a good job putting the bow on top! 😊😊😊

Second, another fantastic episode in the books, Nick! The email from Jeff Tepper had so many great nuggets in it that I had to pause and read it a few times. I don't know why I never thought about crustal assimilation being a norm (or even much of a factor) in a continental arc. This is super exciting to me for some reason despite the fact that I can barely keep up when these discussions turn more technical. I'm a sucker for volcano drama. 😅 Shasta and Rainier are both behemoths, so it makes sense that research on crustal assimilation was easier to come by on them. I wonder if there has been any research on the other Cascades stratovolcanoes on this topic, active or ghost varieties? Or is that new ground Hannah is breaking with her research? Maybe I missed your answer to this question during the show. I need to rewatch this one.
I appreciate you making these exciting geologic storylines so accessible for those of us who don't have the time or drive to devote to doing background research and interpreting scientific papers. Thank you so much! And what a touching clip at the end of this one. 🥹

Russell Ranch may be ugly but he has a beautiful personality
LOL! Ugly Russell Ranch! If you discover subduction, east or west, you are going to get a melange belt of accretionary wedge in between. There must be a Melange belt buried to the west of the Sierra Nevada Batholith in CA that is perhaps an older extension of the Russell Ranch stuff? But you would think it would have made itself obvious adjacent to the El Capitan and Half Dome plutons.
