I love going along with you on these field trips. So satisfying. Somewhat relaxing, and always learning something new. In the KZbin "options" on the right of the screen is "Nick From Home" #33. Hard to imagine it has been two years already, so I just want to say thank you for your dedication to helping us learn over the years. So, when someone asks me, what I did today, I can really say, "I went to the White River Falls with Professor Nick." And of course, thanks to Liz and CWU for sharing you with us.

I have really, really enjoyed watching your videos. I try to watch them as soon as you release them. My geology vocabulary is growing because every time you use one of those terms I look it up. ("What is chert, again? Mafic ... Ultramafic ... Pluton ... I've got to make myself a chart so I can keep them straight.") Beautiful scenery, pretty good camera work, fascinating information. I'm hooked! And some people think that geology is boring. Not with you teaching, it isn't. I've been watching your body of work since 2020 when I accidentally happened upon one of your older lectures on stage with an audience of geology-philes. Your on-site lectures are riveting.

Thanks, Nick. At 19:50 you reference the San Andreaus Fault, I imagine at lower levels (forty to eighty miles deep?) slipping along at a consistent rate, and the upper, more brittle crust stresses fanning to the east and west to form the magnitude of fractures (hayward fault, {Etcetera lol}) in the upper crust, trying to catch up, I think is an entirely plausible concept.

I love these minor "Voyages of Discovery." Going out to look at these sites, reading what those who've come before have observed, and trying to place that within your current thinking is very interesting. Even more so when there's a theme to that thinking across multiple trips. The North Cascades, a place far from me physically, is slowly coming to be a place I can think about in context, getting a feel for how it came to take it's present form and structure. That there is uncertainty involved is even better, as I get to play with different paths to the present reality. Thank you, Nick!

Good stuff. The country is gorgeous, of course, and it puts a lot of earth's history right there in your face, so to speak. I enjoy the out-loud thinking and seeing how Nick moves from one topic/conclusion to another as new rock/evidence presents itself. I've now seen so many Zentner videos that I'm even beginning to recognize some of the terminology. "Recognize," however, is not the same as "grok" ("deeply understand," for those who read, years ago, "Stranger in a Strange Land").

Also, I perceive the earth's crust is full of unequal forces. Sometimes one side of the terrane (hope I spelled it right!) along a strike slip fracture will rise, (maybe miles), sometimes fall or Grabin between two fractures (e.g. Leavenworth and Entiate faults). Oh, this tormented crust!!!

Yes, so a crustal scale strike slip fault forms a shear zone, below the brittle-ductile transition. This means tectonite rocks deformed plastically, namely mylonites. The light colored banded rocks you saw are likely the “light colored gneiss of Wenatchee Ridge”, given the coordinates you were at, having checked out the Washington DNR maps. The metamorphism is undoubtedly connected to the collision of the Insular Superterrane. You don’t form gneisses, schists, foliated and folded rocks from simple thermal metamorphism resulting from the intrusion of a pluton. Buchan/Contact/Abukama/Thermal/High-T, Low-P metamorphism produces rocks like Hornfels, calc-silicates, and minerals like Andalusite in pelitic rocks, in a “metamorphic aureole” that extends in a decreasing degree of effect from the contact of an intruding pluton with the surrounding country rock. The Chiwaukum Schist and Nason Ridge Gneisses are affected by this type of metamorphism, but clearly that is not the extent of it. The fact that there are thrust faults of similar age is also proof that collision was coeval with their metamorphosis. Well-foliated and folded rocks are the result of regional/Barrovian/Ryoke/Mid-to-High-P, Mid-to-High-T metamorphism. However, as you alluded to in the video, plutons are not always simple blobs, their very intrusion requires that the country rock either be stoped away and assimilated into the growing magma body, or moved out of the way physically. Igneous Petrologists call this “The Space Problem”, and the exact processes by which plutons are emplaced in the crust is still kind of an unsolved problem in geology. The emplacement of plutons is connected with the thickening of continental crust, so to some degree, physical moving of the country rock to make room for additional pluton rock must outbalance any assimilation of country rock, otherwise the net thickness of the crust would remain the same. And in order to physically move country rock out of the way for a pluton, that country rock must be deformed, and the higher heat flow surrounding the pluton often will cause those country rocks to become ductile and flow in a ductile manner, and so you will often find shear zones surrounding plutons, and very commonly between two different plutons of similar age or between two lobes of the same pluton. This is the process I would attribute to the White River Shear Zone. In the case of the Nason Terrane schists and gneisses, they were regionally metamorphosed during the Sevier Orogeny, or collision of the Insular Superterrane, and then overprinted with thermal metamorphism related to the intrusion of the Mt. Stuart, Dirty Face, and Tenpeak Plutons, and as I described above, this thermal metamorphism was also likely accompanied by some additional shearing and foliation of the rocks, in the process of making space for the plutons themselves. The second, thermally-overprinting metamorphic event is also associated with incipient migmatitization and metasomatic overprinting of the Nason Ridge Gneiss, and due to the great heat imparted to it both by its depth of burial and the proximity of the Late Cretaceous Tonalite and Granodiorite batholith. USGS IMAP-1661 describes this gneiss as an “incipient gneiss dome”, meaning that it was being squeezed upwards ductily, driven by upwards movement in its migmatitic core. You see such gneiss domes in very high grade collisional belts like the Himalayas. The ultramafite pods in the gneiss are thought to be either tectonic slivers of Ingalls complex caught up during the first regional metamorphic event, or “serpentinite landslides” emplaced prior to metamorphism. I’m not quite sure what the latter means, but BK Kaneda described this in his 1980 master’s thesis, “Contact metamorphism of the Chiwaukum Schist near Lake Edna, Chiwaukum Mountains, Washington” According to maps, the Dirty Face Pluton/Nason Ridge Gneiss contact is NOT on the White River. Where the Dirty Face Pluton comes closest to the White River, it is fully surrounded by Chiwaukum Schist, but the contact between the two is buried beneath recent alluvium. The Chelan 30’x60’ quadrangle map (USGS #IMAP-1661) has a really great cross section going right through the area you were at (White river bridge), showing how ultramafic pods are entrained in the Nason Ridge Gneiss. White River Falls is gorgeous. You are so lucky to live in such a place!

Thanks for the comprehensive description. I've been hanging out in the Lake Wenatchee area since the late 70s (It's just over an hour drive for me) and have been perplexed by the geology. I've collected many fantastic examples of Chiwaukum Schist, Nason Ridge migmatites, actinolite, garnets, and even found a single pure albite crystal over 3" in length. There is a collection of phaneritic albite boulders stacked down a disused FS road left by a mining company in the late 90s who were foolish enough to think they would be allowed to mine in the headwaters of endangered salmon. The protected area is also home to Spotted owl (they're almost gone) and Marbled murrelet. It's a great location for wild mushroom foraging with plentiful morels in spring. Fall has king boletes, white chantrelles (they put yellows to shame), lion's mane, and more.

@@wiregold8930 Wow. Yeah, I have read that pegmatites are an important constituent of the gneiss unit. A few other additions to my post above: apparently there was a M3 (third metamorphic) regional metamorphic event that just post dates the emplacement of the plutons, which also deformed the plutons. The White River Shear Zone has less to do with emplacement of the plutons and more do to with the doming of the gneiss, and in fact, I learned that it is a extensional-sense shear zone. In other words, sort of like a core complex domes, but in this case we are talking about exclusively ductile extensional deformation around a gneiss dome. I highly recommend Richard Zaggle’s 2014 thesis, “Petrogenetic Analysis of the Wenatchee Ridge Orthogneiss”, in which he compares the Wenatchee Ridge Orthogneiss to Archean TTGs (trondjemite-tonalite gneisses), as a potential analog for Archean processes (super interesting!)-among the similarities with Archean TTGs is the presence of Magmatic epidote in the northern gneisses of the Nason Terrane, further afield from the plutonic intrusions, and I also recommend Stowell’s 2007 paper in GSA memoir #200, “Mid-crustal Late Cretaceous metamorphism in the Nason terrane, Cascades crystalline core, Washington, USA: Implications for tectonic models”, which has some great cross section end member models.

Good day, Just a thought/question, Does the collision heating need to be separate from the volcanic heating of the rock? I am thinking a land body being subducted from either side (volcanic arcs on two sides) then the collision of the overriding land bodies with the volcanic arcs closing towards each other. Not really together, but could be very close (geologically) timewise. I am sure there are problems with this, but there are many different geologic movements going on here and that may be an answer or part of the answer... Tony

Reading papers I think I saw there was a second Empress chain style kink, i.e. change of direction of the pacific plate, around 95MA, possibly associated with a Caribbean plate LIP event. Presumably you are in the Farallon plate subduction zone, subducting under either NA or Wrangellia but what direction was the Farallon plate moving and did that change? Were the rocks you are looking at part of the continental shelf, with an intrusion into shelf trenches? I read something like that happened in the Monterey CA area. Maybe change in shear forces due to plate realignment causing a pulse of magmatism along the shelf or in the basin between NA and an accreting island arc. Maybe a failed rift that closed up when the Insular accreted at

Northern Wisconsin, like Spooner eh? And like, right at 11:26 there are mineral crystals showing. I get you are not into the profit thing (I happen to like gold and generally prospecting myself, but that is another story) , but those tell a story from the magma chamber.

If Baja BC occurred 80 - 55 Ma, the metamorphic process must have happened just prior to transit. I saw on the map some part of it was dated 88- 86 Ma. It was probably hot sticky taffy during its migration at depth & pressure. The collision must have created heat, but it may have been hot already. Are there any Teanaway Dikes cutting that far north or do they end approximately south of the MSB? Isn't Wrangelia accretion post Baja BC?

"I wouldn't think of it that way." Wrangellia was part of the Insular Ribbon Continent which accreted diachronously around 100MA. This would have led to widespread slab failure and possible creation of Mt. Stewart Batholith at 96-91MA. After accretion the Insular Ribbon Continent was dismembered by widespread, dextral right lateral faulting, as much of it was still coupled to the trailing oceanic plate. "Terranes within the composite ribbon continent, now present in the Canadian Cordillera, collided with western North America during the 125-105 Ma Sevier event and were transported northward during the ~80-58 Ma Laramide event, which affected the Cordillera from South America to Alaska.

Hey Nick. Amazing video. Is there possibly faults in the Mt Stuart area. Your amazing. Been lacking on notes lately will try to catch up :)

Great video, complicated area to say the least. Look forward to you sorting it out so novice like me can begin to understand. The fault areas up there appear to be many, so are they still active?? And how does all of this tie into BC?? Noraly too excited by the desert, may be bored with folded rocks, by the time she gets there!! LoL

Taking a second look after sleep with a triple shot O-Java.Using the google map links.Nick, you have said WA/PNW is the " DisneyLand of Geology "....... ? Which Ride Were We On Today 😎? Ocean Crust, Igneous, Metamorphism,Schist,Gneiss....Collisions, Shearing, Strike-Slips... Maybe the WENATCHEE/CHELAN BLOCKS are a Two Week Field Course waiting to happen?

Nick are you the person picking up Noraly???? (She's hurt her ankle in Az/CA area.) She hinted at a friend an email pal, 680 kilometers away, able to come get her. You would we know 😉
