Around the 18 minute mark, Nick asks, "Am I wasting your time?" To which, I say, "NO!" I can see how a person could spend an entire day there, making notes and taking pictures (and samples) and just marveling at the scene. Thank you, Nick, for taking the time to go there, and allowing us to go along. Many, if not most of us, understand that just because you're a geologist, doesn't mean you have all the answers, no matter where you are in the world. But, because you are, you're able to help bridge the gap between the viewer and the rocks. To me, "it's time well spent."

I thought I had recovered, but I am back to Nick's videos ! I am addicted. Wonderful stuff ! 😊

I’ve really been enjoying Professor Zentner’s series. Most geology programs are just too general, covering a broad topic like “Plate Tectonics”, “Volcanism”, “Earthquakes”, etc., but viewing his videos I really learn more. I’m a geologist, I don’t want to just rehash my first “Introduction to Geology” course!

Nick. You are correct. Most migmatites are generally avoided like the plague. At least there's more on it than the ones in Ontario. We got no one studying the migmatites in Ontario. We can't even decide on how to classify them. I divide them into 2 main types. 1) Migmatites where melting has obviously occurred and penetrates the host rock and present within the unmelted part (arterite migmatite). The second is like what you are looking at, where any melting is hard to see but the migmatite was right at or really close the melting point. I call that venite migmatite.

This is exactly where I went after hearing you talk about Lake Chelan. It’s five minutes from my house. I’m thrilled to hear you talk about it. I can’t wait for more information to come out. 😍

I'm a rock hound..... beautiful rocks. Thanks Nick!

I could look at this all day Nick 👏👏🥳 that cutting was a fabulous viewing

Those rocks are mesmerizing. Thanks for showing all the crazy patterns Nick. Really enjoyed it.

Very sharp and clear picture

Those rocks really are impressive. I like rocks that show off.

3 minutes in and I'm afraid I just gotta say, Looks like some very nice Gneiss!

Really cool spot. Beautiful Migmatite.

You're not wasting my time. You enlarge my experience of the world, and in so doing, my experience of life. Thank you.

My girlfriend noticed the heart pattern over Nick's right shoulder. She said the rocks love him.

Some of the roadcuts where these rocks are exposed with fresh surfaces have that wonderful, characteristic, swirling-band migmatite texture. That’s how I spotted them, just driving by at highway speed. This texture captures the exact temperature and pressure conditions where these old gneisses were partially melting to form new plutonic magmas. It’s not something we get to see very often, most migmatites are now deeply buried in the roots of our mountains. These rocks are special!

Cretaceous graffiti…just glorious!!! Thanks!!!

I have never seen an outcrop like this from my travels from permian sediments in Kansas, through canyons in Colorado rockies, up over the rockies into Wyoming and Utah; can hardly wait for the Chelan Migmatite explanation; get it Nick.

This is, perhaps, one of the most tantalizing videos I’ve seen. It reminded me of what I observed when I went on a motorcycle ride through Kings Canyon National Park.

I remember when Nick did his tour of the CWU campus and showed the various rocks of Washington state that were on the grounds, I immediately fell in love with the beauty of the migmatite and I asked where I could find some. As soon as Nick entered the area where he sat down I recognized it as the place where I first saw the migmatite and I just assumed the leucocratic veins were quartzite(I assumed every white vein was quartzite back then) so it was really awesome to see that Nick was in the same place I was at a couple years ago when I first explored the Chelan migmatite. still one of the most amazing and beautiful rocks I've ever seen and it makes me want to go back to Chelan.

okay, i am hooked, going to get the van gassed up and come up to lake chelan! most beautiful rock i have ever seen!!!!

Awesome two videos in two days. Keep cranking them out Nick. Need everyone to like, comment, and subscribe so we can make his channel grow and reach more people.

Yay you remembered your Pick Nick!! Not going hungry on this video!! Ross lake and Pasayten faults might be like the green beans and they got folded in half once they got docked with North America 🇺🇸. A train of terranes crashing in behind them capped by the Still Champion can’t be beat the Large and In Charge Igneous Province that got tore in half and is Still docking in Alaska today! Started the Crazy Eocene fireworks 💥 The one ☝️ the Only SILETZIA!!!

every time I drive up that grade I have to slow down. Dammit Nick; now I need to stop. (sorry Patrick)

Thanks again for another great video Nick. Really connect with your chat on your style as I too need those toned down views from the heavily loaded factual views that are important in science, but can cause over load. When I have more of a basic view, it makes it easier to add the factual layers on top of the basic layers. That why I love your classes so much. Thank you Nick

Really beautiful rocks, so complex

I’d like to have a countertop made of the migmatite. It’s hard and has gorgeous patterns which would be outstanding when slabbed and polished.

Okay, I just finished the video, and I'm also officially excited about what's to come. Your excitement is sure contagious, and folks who haven't seen the Exotic Terranes A-Z series, might want to watch them before the beginning of the Baha-BC series. Besides being a good series to watch on its own, I am sure there will be many references this winter.

Gathering momentum. Cool build-up. 👍

"I might be wrong with that, but lets just roll with it" That's how you communicate ideas. Love what your doing Nick!

I hope you are as tantalizing with Liz as you are with us...(?) Super excited!!

Chelan!!!!! Deeply moving in multiple ways 😆

I love your clear explanations and I really appreciate your videos!

Watching it again already... reading the comments from the old fans and new ones, part of the fun in watching is the extra content in the comments.

OMG!! Those rocks are so amazing!! If we were there I would give my poor husband a double hernia lugging some of that stuff home. Thank you for sharing another amazing place Nick.💕

I have been stopping and looking at the migmatite there. I live in Chelan ❤. I’ve watched your Lake Chelan video 3 or 4 times! That spot boggles my mind. Plus a great big feeder dike there.

We have some pretty cool formations in Connecticut too. I can spend hours coming through rocks like the ones in this video. Everyone I know thinks I'm weird. Thank you, Nick. I don't feel like such an outcast anymore.😁

Thanks again, Nick, for another fun geohike! Yeah, I can see why geologists like to overlook this section. Can't wait for the Baja-BC series where we hopefully find out where this leetle terrane pops up south of Washington. Looks like it all went through a mix master of layering, squashing, heating, uplift, and sideways squishing with intermittent faulting and traveling just for fun. Oh, the poor kids who could have this on a test! Glad to hear they are collecting zircons and some are trying to map it at least!

Those Chelan migmatite rocks look very much like the rocks my son and I were seeing on our hike up Phelps Creek to Spider Gap above Lyman Lake in the Glacier Peak Wilderness this summer.

Thank you for an interesting Saturday afternoon 😊

Great video and questions Nick! I am also excited about the direction your teaching sessions will go this fall. I am a retired math teacher and my son is a research materials engineer. We have watched all your videos since March 2020, and when he visits we take out the Roadside Geology guide and head out to explore the places you talk about. All this information connects, and the more I hear about the geology of Washington and the North Cascades, the more it makes sense to me. In fact, I have learned so much from you and your guests that on my own I have started reading "Earth Materials: Introduction to Mineralogy and Petrology," by Klein and Philpotts. Thanks!! Keep it coming. Mary

Thanks Nick! Always a good time learning from you about my backyard!

My family and I live in and around chelan for around 50 yeas. Very interesting to hear your 2 or 3 programs about our little town and lake geology

While the textures are so convoluted, it's all in the details, like can't see the forest for the trees. Thanks for the video Nick.

The colors are lost when you zoom, but after a few seconds they come back. Maybe by iPhone 85 they'll have it fixed! LoL Because of your classes the last couple of years, I just got back from a 14 state trip, with a bag of rock samples! Now I get to try to figure out what I all have. By-the-way, my new hammer is not new anymore! Ha. I even had an opportunity to pick up a Megladon (sp?) Tooth! I'll be my grandsons favorite grandpa for awhile! (Not near any rocks! - around Chesapeake Bay area). There were outcrops that I've never seen you deal with, until possibly today! It was in New York, New Hampshire and Vermont hills. Really great looking stuff. And to quote you, " I could not stop" taking samples and pictures! Thanks Nick, I'm ruined, taking pictures is just not good enough anymore!! LoL

Great stuff, Nick. Keep it coming! I can't get enough Washington geology.

Of a very beautiful convoluted rock.

Prof. Zentner, hello and it's amazing how much "Geology" is to be found within such short distances of each other in your area alone! Yes, recognized the Crystalline Core drawing immediately (27:24) and my head is still spinning with all the information you captured within it:? Let's keep on learning!

Your enthusiasm and excitement inspire us! It's so fun to see examples of fractures and timelines, and to just be with you. Very much appreciated. I just watched again, on laptop (vs cell phone) and that's just crazy stuff, mixed and blended. Wow!

Glad you have better balance than I walking on the drop off edge

Always interesting with Nick

You have me excited too. See you soon.

The picture that I am getting watching these summer field videos is a vision of how north amercia(like a snow plow) ran into several island arcs and the accretionary material kinda sloughed off to the side, or maybe sides, as the continent kept drifting southwest.

Thanks for sharing the incredible views and science.

i love migmatites! Theres some awesome outcroppings of it in Western Australia as well, they're so freaking cool! :)) awesome video

I can tell Nick likes to eat. Well I do too, and if there were a clone channel about my State of Oregon I could watch, I'd have "meat and potatoes", and head to Washington for "cake", I swear. We need this down here

Thank you, Nick!

Camera colors going crazy! Awesome site!! 100Ma is like yesterday for us here in NYS! Good luck from a Union College Geology Grad. and 20yr ES teacher.

Thank you Professor Zentner

You are not wasting my time Nick. It's like looking at a mix of ingredients that got frozen in time before completely blended. It's awesome. :D

There's something that looks similar to this migmatite in the mountains south of San Joaquin Valley, in the mountains on the south side of a valley called Mil Potrero the SW side of the San Andreas Fault. The SAF runs along the north side of Mil Potrero. My parents used to have a vacation house in the area so I used to hike up to the waterfall where the migmatite is. Higher on the mountain the rock is more like granite. I find myself imagining that this came up from the west coast of Baja California and I wish I knew more about the geology of that place. There's a big hook on the west coast of Baja CA called Punta Eugenia, which I imagine as the place from which the south end of the block moving north along the coastal right hand faults of Southern CA came, and another on the mainland of Mexico at Puerto Vallarta which has to be the former home of Cabo San Lucas.

Love these Stunning Chelan Migmatites! 😍♥️ Great ramble Nick I appreciate you are learning with us & are willing & humble to express that. Note at the end of this vid you have a perfect heart 💙in the CM resting against your right shoulder!

Salt water taffy!! Thanks Nick.

Love the enthusiasm and passion. A willingness to chase ideas.

i would not have made it 18 minutes in if I didnt like looking at rock... just looking. this Chelan migmatite deposit is worth lots of looking.

Those rocks look like they were formed by a horrible chaos

I also am "ready for more" !

Greetings from Chile, nice videos!

The noise is not a problem for this Zentner fan.

Thanks for another exciting glimpse into our fascinating geological past. So many questions, so much more to discover! And also thanks for the tip for a new book to hunt down and acquire, lol.

🤯...my God that Rock is something else🤯 so cool

Give me a break. This is beyond amazing.

How interesting, i JUST learned about the Spexman migmatite on the wenatchee museum randy lewis tour today! Was super cool.

@19:20 use a laser scanner to map the rock surface geometry. Take multiple camera angle shots all along that surface (drones, maybe?) apply the surface texture image to the rock geometry earlier captured, then model the color contrast boundaries as semi-rigid sheets extending into the volume behind the surface. Well, that's what I'd try, to start.

Thank you Nick, this is my very favorite rock outcrop so far and I can get to with my artistic joints too

Metamorphosis unlimited! Absolutely phenomenal, i gotta go see that with my own eyes!

I have so many hypotheses running around in my head and so many questions about where the major faults are in relation to the CMC. Thanks again for another great video Mr Zentner!

The past few videos i thought...I need the white board....I saw it through and hopefully i am understanding all the previews for what's coming later in the fall.

Dang. So interesting. WHAT THE HECK, indeed. Beautiful drive along the Mighty Columbia and so much to learn.

13:33 Nick has his hand on a bull’s face. Or is that a goat? Wake up, Nick! 😂

Hello, I live here in Omak, getting excited to learn more local geology if and when you get into the ORB.

Beautiful. Pick some up for me. Rocks rock

Dramatic indeed!

Blown await! To think I drove through this area in May and missed this. Next trip.

Nick, for Baja BC can we keep a RUNNING TALLY of proposed fault offset distance on a physical chart on the wall that is compiled incrementally during the winter session? Would love to see each session reinforcing these thoughts of proposed movement, but individually emphasized and even Challenged, to then reveal both a "conservative" estimate and a "plausible" estimate of proposed translation over a specific time window. Keep following your instincts, absolutely love this channel! And don't be so hard on awestruck Nick , sometimes the lack of the right words can convey the significance just as well if not better.

So beautiful.

I always learn from these Breathe easy! Just got a 13. This encouraged me to get better acquainted with the camera.

I’ve got to go there and pick up a couple of buckets full of big chunks for slabbing and polishing.

What a complex rock. Nick as I found out I have to wonder was the Chelan going up and down or was the sea level and possibly the knappes folding over? It would seem the whole West Coast was doing the elevator ride, Westward subduction? What an amazing set of plates and bowl that would make!

Thank you for addressing the two feeder dikes as I would have fixated on just them. They stood out like a sore thumb!

Great sense of humor

You finally got it. The Ross lake fault is like the San Andreas fault. It's a plate boundary fault. It brings junk up from both sides not just one side. The guy in Arizona talked about this. Good to see you Roberta age 73

Thanks for the video. This video reminds me of making fudge. When you start adding the marshmallow cream you get all kinds of weird swirls. Maybe as it was forming it just didn't get mixed as well in all places. What did the area look like back then? Were the rocks going up, was the land going down exposing the rocks, was the land going down and the rocks going at the same time? Did the rocks come up because of the fault and change the fault? Was this area weakend because of all the faults?

It is good for the soul to occasionally look at something and just go: "Wow." Also I wonder if the iron inclusions are hints to what was going on.

Nick, from reading about migmatite on Wikipedia, the light a dark striping comes from "exsolution" of two components that were formerly a *single* melted composite material (presumably, of much older origin than the exsolution event), which then separates into the two main components, forming the bands. According to this, we are *not* looking at leucosome (light) intruding into melanosome(dark), but rather it is the result of leucosome and melanosome materials formerly dissolved within each other, becoming separate macro components with the swirling or banded appearance that you (and I) were marveling at. If the above is correct, does the exsolution event occur during the elevation process? Start as buried granite 30 km down (?) and ends up at the surface, as migmatite?

This very hard rock type has been collected and an example of which has been placed in the CWU boulder garden. This is where it came from in it's natural and full scale site. The oldest and sexiest stuff around in Washington state!

Beautiful! Thank you Nick!

Thank You ! It’s WonderFull 😊 I said HI YAA for you…

This area is phenomenal!!!

I see a hammer!

looks like 90% or the gneiss that we got coming out of the Hudson and east river
