Good old Granite Falls: I had property there..."before geology" in my life. 👍🏼 Learning enclave and host, and stock, seeing with new eyes. This is a real pleasure. Thank you, Jeff and Nick.
I am so glad that a few years ago when you ran out of material to share with us that you decided that we would forge ahead and learn new things together. Today was another learning day. Thanks Nick and Jeff.
I love the "In the field" videos. Always great scenery combined with very visual and well explained Geology. As much as loved "Mappy McMap and the White Board", that have by the way have become Icons in their own right, this goes to another level. Pictures paint a thousand words. And all this is free.Thank you so much for everything over many years Mr Zentner.
Thank you Nick, I learn something every time I watch your channel. Thank you for the time, and showing us these wonderful places. I may only dream of seeing these places, but it's nice to know they exist. There is so much more to learn.
Thank you Jeff and Nick! I have seen those "inclusions"/"enclaves" many many times and always wondered about them. I am not a geology student really, and quite a bit of Nick's presentations are over my head, I am glad to be able to access the opportunities you provide to add a bit more to my loosely understood geology. Thanks again to both of you for past and ongoing presentations.
Great episode. It is hard not to be incredibly impressed by Jeff Tepper. My impression of him is as follows: (1) By virtue of his personality and demeanor, Dr. Tepper epitomizes the saying: “A gentlemen and a scholar”. With him, it is clear that a big mind does not have to speak loudly or brashly. (2) He is superb at explaining a things simply and is super patient-he must have been a fabulous professor. (3) His slab rollback and breakoff theory still seems very compelling and makes a lot of sense. Thanks Nick for having yet another outstanding episode with Dr. Tepper. And finally, the scenery, as in all your videos, was stunning. We are so lucky to have you making these videos for us “geologists wanna-bees”!
Fascinating petrology field trip! Dr. Shamloo’s lecture on volcanoes and “mush” came to mind. This really helped me start to understand this process! Thank you!
I have long wondered why liquid mafic enclaves, to use Jeff's wonderful term, are immiscible in granitic melts. The explanation and distinction between the different types of inclusions (liquid vs. solid) makes complete sense. Thanks, as always, to you and all your guests for enlightening me and so many others who love learning.
It’s so cool to learn with you about those basalt “enclaves.” This is by far one of the best uses of internet technology out there: Streaming audio/visual educational info, bringing remote locations and incredible expertise to the home. Thanks for all you do.
I take my Rc rock crawler there all the time. And I love watching the salmon jump up the falls. Also just wanna say thanks for all the work you do. You inspire so many people. Including me. Last month found myself up blewett pass. Found my first fossil. One a leaf the other I'm not sure. Can't wait to go back! Thanks Nick
I love your videos. I grew up in Chelan so I am familiar with the area much of what you are talking about. My father had a degree in geography, so he had a good knowledge of geology and we had many conversations about rocks, etc. One of the last things I was able to share with him was your video about Lake Chelan, which he greatly enjoyed.
Thanks for this fun field trip NIck - I am loving these sessions with Jeff Tepper learning more about batholiths and plutons! Now I am prompted to look at some of the ice age erratics around Wenatchee to see if any of them have these features, and ponder what that might tell us about their origins.
Snohomish County Public Works had a large quarry pit that featured part of this pluton, but it was tested and found to be rich in arsenic, so was abandoned. Arsenic in the local groundwater remains an issue. Radon intrusion into homes in the area is also associated with this pluton.
I would have thought that the intrusive material was just a stone caught in the sediment, and it was all turned into a conglomerate. I learned more again today, and it was great.
😮🎉 If I had a head exploding emoji I would be using it. First of all- I love granite falls with the river and rocks. Have loved it since my earliest memories camping up river. More importantly- I always wondered what those dark inclusions were and how they got into the granite. Now I know!!!!! My brain is now full. No need to learn anything else. This is like the rosetta stone for me. Keep up the good work From Battery Fully Charged. p.s. Was walking along Puget Sound today at Richmond Beach. The rip rap for the railroad had many granite boulders with both angular and oval basalt inclusions!!! The anglular inclusions were a different shade of dark grey that the oval ones.😊
excellent such a great piece of taffy or enclave added to the "mix" both literally and figuratively! lol thank you for your playfull wit and ideas around such great scenery and geology in place and time, the game is afoot! Watson says holmes.. love love love i support you
I have some granite boulders with enclaves and I am going out with my hand-lens to check boundary grain size. Thanks for the geology project! The scalloped boulders are great. I noticed how armored the bed was. Everything was locked together with sparse loose gravels. Spring runoff must be a torrent.
Thank you Nick - this was an incredible video. One of my favourite rocks is Conglomerate from the BC Cascades. I now understand so much more. Look forward to Jeff Tepper spending more time with you ... possibly in the Sierra's? (or in British Columbia?)
Outstanding video. I've spent much time in this area and now the rocks and geology are making more sense. I would have guessed xenoliths as well. I hope someday you will do a piece on the geology of Mount Pilchuck, just up the Mountain Loop Highway.
I've always felt SF of the Stilly west of Robe is much younger than east up valley due to the shape of the valley. Deep, sweeping valley walls and oxbows turn into steep walled canyons all the way past the fish ladder. Add to that the thick layer of clay, which is indicative of pooled water, and I believe there was a large lake that was most likely formed due to a lahar or a glacier impounding water around Robe, that eventually broke through and carved out Robe Canyon.
wow great stuff I'm currently in Saudi in the Arabian-Nubian shield doing some general exploration work, been on/off here for over 25 years now, its, excuse the local pun geologist's mecca, endless barren outcrops without as much as a blade of grass to be seen...one friend commented its look very barren, yes I replied arent I lucky. My current base at the door step, has mafic dikes mingling and fragmenting (sub angular-sub round) in the local tonalite pluton Jeff Tepper's comments will give the morning coffee over the backyard tonalite a bit more to ponder over than usual. BTW USGS previously had a big presence here in the shield/kingdom, some of your distinguished guests would likely concur first hand...thanks for your great informative videos...the other spelt Jeff...Geoff.
Guesses of that plant between you and the rocks and licorice fern in the first location is 1) salmonberry, 2) goats beard, or 3) black cap raspberry. Any of these should be, I think, less than 3 thousand feet elevation most of the time. I think at Mount Si that's about where it cuts out. Highest I'd expect would be five thousand. More likely 1000.
Does Darrington Phyllite have anything to do with the Granite Falls pluton? If the Darrington formation was once seabed that subducted under North America, what forced it all the way up to the surface?
I know you are trying to get back to Cascade geology. However, I am curious about how Jeff Tepper and others would explain the subduction zone arc like Absaroka Volcanic Complex?
Thank you again, Dr. Tepper. We are so fortunate to learn from your presentation, as usual.

I love Jeff, thanks for bringing him, or coming with him, to all these places!
I had NO IDEA about these fluid magma enclaves things! Fascinating!
This the wonderfull way to learn geology, i don t want other🎉 thanks very much Sir Jeff and Sir Nick...another word Enclave
Thank you both, for this great video. It will be so much fun watching the A-Z series, with these "sneak peaks" we've had over the summer.
I wish learning had been this much fun in high school.

Greetings, Thanks to you both for sharing these observations.
Dr. Tepper is great! Enclave, Enclave… 👏 👏👏 Looking forward to seeing him live in the Friday series as an encore.

Thank you, Nick and Jeff! I feel that I've learned something new as always.
Field videos like this one are enlightening.
wish i could have come along! Such gorgeous views of the river and a wealth of knowledge
I love your videos. I grew up in Chelan so I am familiar with the area much of what you are talking about. My father had a degree in geography, so he had a good knowledge of geology and we had many conversations about rocks, etc. One of the last things I was able to share with him was your video about Lake Chelan, which he greatly enjoyed.
Wow! I learned something today! I see these all over in the granite north of Lake Superior, thanks for teaching me what they are!
Nicely done. Good explanations of what we're seeing without getting too technical for non-geologists.
Interesting as always! Thanks Jeff and Nick. A lot to take stock of in this video!
Thank you, Nick and Jeff.
Viewing this video on my new tablet, excellent scenery.
Man, Jeff is really good. Love this video. Great spot. Thanks Nick.
Beautiful, interesting, educational, historical
Thanks for all the hard work on these videos!
Thanks for this fun field trip NIck - I am loving these sessions with Jeff Tepper learning more about batholiths and plutons! Now I am prompted to look at some of the ice age erratics around Wenatchee to see if any of them have these features, and ponder what that might tell us about their origins.
Wow! Love learning new info about the formation of the place where I live!
Just awesome - don't know what else to say! Even I get this! Although I'll watch again of course. Thank you both so much!
Thanks Jeff, for adding to my meager knowledge.
That was fun & educational. Very interesting. Thanks for sharing.
Very Interesting. Now I an another day trip planned. It is good to know what I am looking at. The best to Jeff Tepper. 😊
“I love it when a plan 😊comes together.”

Aha, Mafic Enclaves!!😏✨Thanks, Jeff & Nick!!😃💞💛
Thank you!
I would have thought that the intrusive material was just a stone caught in the sediment, and it was all turned into a conglomerate. I learned more again today, and it was great.
"Zihuantanejo" haha that made me laugh. I just watch Shawshank again recently too. 94 is an all time year for movies.
Very cool reveal when you climbed on the rock. Laughed out loud at "The date of this has gotta be the next Tuesday or something."
Another good one Nick👌🏽

The scalloped boulders are great. I noticed how armored the bed was. Everything was locked together with sparse loose gravels. Spring runoff must be a torrent.
While watching this video, I kept wanting them to check out THAT rock, or THAT one. Am I starting to nerd out on rocks? Yeesh!
Thank you Nick - this was an incredible video. One of my favourite rocks is Conglomerate from the BC Cascades. I now understand so much more. Look forward to Jeff Tepper spending more time with you ... possibly in the Sierra's? (or in British Columbia?)
Very interesting thanks again. Dorset UK.
Ned Zinger, the Silver Slugger of Geology. Always a hit.
Jeff Tepper will always be to me the man who wants his hammer to be persuasive. And I have to say, he is no less persuasive then his hammer.
Outstanding video. I've spent much time in this area and now the rocks and geology are making more sense. I would have guessed xenoliths as well. I hope someday you will do a piece on the geology of Mount Pilchuck, just up the Mountain Loop Highway.
Gosh, I just learned soooooo much! Thank you Jeff and Nick! I see inclusions a lot, iirc the Ohanapecosh had them in one of the videos.
Lava lamp? Thank you both no bones were broker, and no feeling hurt. Good job who knew!
Hot wax blobs rising in a lava lamp.
A lava lamp of the most literal form
Had the same thought
I love field trips!
43M year old lava lamps. Who’da thought.
I've always felt SF of the Stilly west of Robe is much younger than east up valley due to the shape of the valley.

Some videos deserve two thumbs up 👍👍
Hearing the description and origin of the inclusions, my mind went to lava lamps. The rocks at the falls are parts of a frozen lava lamp.

Funny, I think of 'Mokume', seeing those rocks molten together.
I just keep looking at the dark boulder behind Jeff. I wonder if the whole thing is basalt.
I think i have something similar in my area. Great field trip.

Any of these should be, I think, less than 3 thousand feet elevation most of the time. I think at Mount Si that's about where it cuts out. Highest I'd expect would be five thousand. More likely 1000.
Now I'm wondering if I can find granite slabs for counter tops with large inclusions in them. Interesting!
I've seen enclaves many times. Now I know what they are. :)
More Jeff Tepper please!!
water 'n' rocks 'n' trees, oh my!
('n' geology)
You lead a rich life!
Just itching to drop a line in that river…
Haha.. That's what I was thinking. Seems really low right now, but I might have to take a drive & see what happens.
Hmm. Definitely Salmonberry / Thimbleberry along that stream. That's low elevation. Hmm Also some Maidenhair fern.
Does Darrington Phyllite have anything to do with the Granite Falls pluton? If the Darrington formation was once seabed that subducted under North America, what forced it all the way up to the surface?
Fascinating! even for an O+G guy like me.
Sandiego has lots of mafic enclave granits.
I know you are trying to get back to Cascade geology. However, I am curious about how Jeff Tepper and others would explain the subduction zone arc like Absaroka Volcanic Complex?
Total newbie here: whats that huge dark gray boulder that they walk around. Its in the background most of the video.
"LAVA LAMPS!" 😆
Was that John Calvin Reed Jr that Jeff mentioned as having found evidence first in Sierra Nevada's?
Thanks for video. Super interesting. How can I find the map on your website? I clicked on the Cascades but it took me to the CWU website and no link.
Magma bubbles in other magma.
Are granites forming (much like this area) under rainier, for example?
Is the darker looking exposures at the waters edge actually a basalt dike?
have you guys ever put a gieger counter on some of this rock, does it still have any radioactivity?
So this basalt is basically a lava lamp blob inside this granite... weird.
Said half the comments once i started looking 😂
Luv, all your programs.
How do I find your:GEOLOGICAL MAP OF GRANITE FALLS 7.5-MINUTE QUADRANGLE, SNOHOMISH COUNTY, WASHINGTON.
1:00 - you mean like 1949?
What kind of bear.. black or griz¿
