CWU's Nick Zentner leads an outdoor classroom session overlooking Wenatchee, Washington, USA. Saddle Rock Rhyolite and the Ice Age Floods are featured.
What a treat to wake up and find another 351 field trip ready to view. The volume of water that flowed past Saddle Rock is jaw dropping. Thank you for bringing us along.
A lot of TH-camrs upload their content hours or even weeks before it becomes available to watch. It helps them be able to release content at a more steady pace since content creation isn't steady paced but viewer expectations are
Never be disappointed when Students do not voluntarily reply to a question. They are young, the subject is new to them, they have soooo much to learn, so much to understand about correcting oneself if they are wrong. Sometimes its easier as an "Armchair Geologist" at home to think X Y Z. These are not those people, these are the future Geologists. Its great to see a programme out in the field again.
Great work with the Young Geologists. When I was a Young Man I always enjoyed the study of Earthly Formation. I then went into the Construction Trades and eventually settled into Excavation Work. I found myself always watching excavated materials while operating equipment with wonder and amazement. I have now found Nick Zentner and his exciting work with Clear, Concise and Very Understandable Presentations. Love It!!
I have been watching your videos for months now since I found them. I find you extremely interesting. I wish I’d had professors like you when I was in college back in the 70s. Keep up the great work and keep posting. Great job.
I love your courses, Nick! Don't get me wrong. We have awesome geology in Norway. But yours is so exotic, and you explain it so brilliantly, I'm on the edge of my seat every time I watch one of your videos. Your students must be absolutely thrilled to have you, and I figure that they're so quiet here is because your climb has wasted them (too much Xbox? 😂). Thank you for yet another GREAT lecture! 👍
Looking at that scenery brings back so many good memories. I spent 8 years working for Chelan County PUD as a contractor installing their optical network. The last fiber-optic tower I spliced was in Manson, at the water tower looking down on Lake Chelan. One of your lectures about Lake Chelan genealogy being the 3rd deepest lake in the United States. How it was formed by glaciers but not a Alpine glacier. A continental ice sheet from Canadian 5000 feet deep intersecting with the Okanogan I sheet digging a deep hole in Lake Chelan below sea level as a result.
That's way up there : 6'5" above the peak elevation! What a view to visualize the ice age floods. A terrific day for that hike. Beautiful. Rhyolite.... New information for me, as well as possibly older major floods......very interesting to consider! (Knees! 👏🏻)
I'm too old and too long a flatlander to manage a thousand-foot elevation gain in what appears to be a fairly short distance, but the view is impressive, as was the description of the Wenatchee Basin at peak Ice Age Flood. Happy to see students out on a genuine field trip, which will make for a great story over dinner in 10 or 15 years when they're at a different point in life. At their age, I was one - still am one - of those who never answered a question unless I was forced to do so, or I was absolutely certain. I'm not certain about much of anything geological. Well done, professor!
What a treat to wake up this morning to a new geology video from my "backyard"!!! It even had a brief cameo from my home base - the Malaga Slide, lol. It was exciting to realize that Wenatchee was the last gasp of the Crazy Eocene slab rollback event. I was hoping you were going to touch upon possible reasons that the Columbia River eventually "chose" to make its path through the CRB exactly here at Wenatchee instead of continuing to go around. I know it is related to the uplift event, but why exactly here at Wenatchee? My speculation has been that it was related to the fact that we are more or less sandwiched between the Entiat Fault and the Eagle Creek Fault, potentially creating weaker area in the CRB at this location, which then got exploited by the water as the CRB began uplifting. Thanks as always for sharing these field trips with us!
Such beautiful scenery! It makes me wish I were young enough to clamber around on the cliffs to see the geology in person. Thank you, Nick, for sharing this with us and thank your students for allowing us to join.
I expect soon to see a map that labels the CRB the GCC (German Chocolate Cake). CWU is fortunate to have Nick and all of the students are even more fortunate. A great teacher who always reminds me of Jim Birk who got me interested in geology by asking questions and having the students think out loud... A great teaching technique.
What an awesome class! I remember visiting the San Andreas fault in my first geology class. I can still picture some of those images all these decades later. It's unfortunate that most people don't get the opportunity for field trips like this.
The mountains I climb (Scottish Cairngorms, Arrochar Alps, Torridon etc) are generally older (and glaciated), but I do love looking at things like the Glen Tilt fault (or even the Largo Law volcanic plug I look at from my house) through the lens of Nick's teaching.
I can see all your stories, Nick, SO cool!😄✨What an awesome Field Trip day it was for your GEOL 351 students at Central Washington University!! I appreciate you for sharing the day with us, thank you!! 😃💗
Thank you Nick, this made my day. I take groups around my local geology and your teaching inspires me to improve my talks,. Nick, your are my geological hero.
My brother still lives in Wenatchee he just went through a mining class in order to enter liberty Goldmine. I guess he knows some of the individuals who own the mine. Hopefully he'll find some gold.
Nick, next time you go back to Wenatchee drive up to Mission Ridge. There are major flood deposits on the drive up to the Mission Ridge ski area. The monster floods were much much deeper than the later flood chapters.
As a flat footed gal, I have a life long relationship w sloped slippery w gravel places, so I'm tense every time you are up in these kind of slip and slide slopes... but fun for the strong hearted and sure footed Prof and students and audience!
Your visits to some great Washington state geological sites never disappoint Nick! And good fodder to make the students do some practical observations.
Compared to some hikes I went on in the Cascades, it's a short, fairly steep trail. This is the time of year to go. We will soon be in the 80s to 90s. There is no water and no shade along the trail. Usually, we hit 100+ temperatures the 5th of July or soon after that date. The rattlers are just getting up for the summer now. Once it is hot, lots of them are reported on all trails on the hill sides behind Wenatchee.
This makes sense about the older floods. Pateros confuses me I’ve been going there looking at those dropped rocks right where it turns to 153. The confluence of Twisp River. Also where migmatite is by Alta lake.
Spending time in the field with a Professor of Geology ... PRICELESS! Thanks for the video Nick, I appreciate it. I recommend visiting the Pacific Tectonic Plate in Palm Springs, CA, where you can look north to see the American Tectonic Plate literally standing still as you move an average 2 inches per year NNW. Ride the Arial Tramway and get a closeup view of metamorphic rock.
Nick, you talk about the CRB pushing the Columbia River west. I believe this makes sense. However, instead of it being a relocation to the west, I sense that it may be more of a directed merging of the Columbia with another existing river in place of where we call the Columbia today. So essentially, two rivers may have become one, rather than one sliding west. I have not seen that trail since they reworked in late 2022. That is nice! Tom in Wenatchee
Loved the class. In my younger years I took hikes often and always have had a love/hate relationship with rock. Too bad I didn't major in Geology. Thanks again.
IIRC, there was a spear point cache over on the eastern rim of the CRBs at a specific elevation one of Nicks older videos referenced I think. Would love to learn a bit more about that, and reiterate the significance of the elevation they were found at.
I think you may be referring to the Richie Clovis Cache. I was living here when it was found. Since I have an anthropology degree I took my children to the site while it was being dug. That is located on the edge of an apple orchard near the road on top of Pangborn bar. It is about a mile and a half past Pangborn airport. So it was a bit above the highest shoreline during the ice age floods. The site dates 11 to 12 thousand years bp.
@@Anne5440_ That sounds like the one referenced, might anyone know of a documentary type video to See and learn a bit more about how it was found and any interesting associated details?
@101rotarypower there are a number of articles and papers on the web. Just search for the site. I have a few saved for my anthropology update study. Not actually my branch of anthropology but an interest of mine.
I wish you could do the same observational trips to the countries abroad to see amazing geology outside the States. I looks so amazing being on your trips. Maybe monetization of your channel could help financing those trips as well as helping getting the equipment needed for them, maybe finance somebody to do the film production...
A wonderful trip and your class is doing great thinking. I'm so thrilled to see the view from up there. I've lived here in E Wenatchee for a very long time but never been up to the top. This was a really interesting video for me. Doing some searching about the rocks in this valley is on my study list. I will watch this more times and take some notes.
Eek too high I'd probably fall off but great view. Thanks for taking us along. You must have good balance. I always find d it easier going up and riskier going down so please be careful everyone.
The difference in elevation between George (calcrete) and Wenatchee is virtually identical (+/- 2ft.). It is not difficult to imagine numerous flood events depositing basalt and other rocks from scattered locations and creating calcrete as well over vast periods of time. The criticism that there is insufficient evidence of water having scoured the landscape into what it is today is the same criticism Harlen heard in his day. Even if ice age waxings and wanings are accounted for, (120,000 yrs.?) there would surely be doubters.
You've a great group of kids, Nick. It's been great to see them both on video and live. Wonder how many of Adrian's "friends" 🐍were keeping an eye on you guys!
Wow! Some more food for thought. Hope geologists find more evidence for that Okanagan flood theory. Maybe need to do more drilling through that tough cake....
@Poppageno no idea. From Nick's previous videos there are several papers out there that cover the Bar. I just did a Google on it, and there were some as well as a Nick video from a year ago. Most studies seem to be about the big erratics, but I am sure there should be some on the sediments as well. My point is if they want to find older floods, they need to dig deeper and I would guess the data would be in the lower rock.
The question,should be,how deep are the sediments and the age is way further back probably,because anything that is spoken is speculation.The direction of water flow probably came from a variety of locations much further than is currently visualised,the rocks make have slightly different chemical compositions,depending on subducted material and polarity.
Paleo Mag showing a deposit 1 mya we have uplift in the Yakima Fold n Thrust Belt for 3my Lifting Calcrete up 2,000ft with the CRB below it. Clearly seen on Manastash Ridge on Hwy 82/97 headed towards Ellensburg. I do wonder if there was a set of two ocean trenches 75 mya as our crystalline core was docking. One in front of the North American Craton the other in front of Siletzia. The CRB being deposited into these deep like a gutter filling with leaves. Rerouting rivers going to the ocean. This coincides with Triple Divide Peaks formation in Montana. This does beg study for the purposes of the hit n run plus Siletzia slamming in.
When hearing the story of the Columbia river getting its way delayed by lava, I have that scenario before my mind's eye that gets suggested for river Rhine in case the Maria Laach volcano has a big eruption again: the Lava would form a dam in the Rhine valley and block the river for decades, maybe centuries, until cooling and erosion would have weakened the material to a point where the dam gives and the lake formed behind the dam would empty itself in an unpleasantly short time. Could such a thing have happened with that big flood of Columbia river? This would be an unimaginably violent event, explaining the very high marks of flooding found there.
It is interesting that the flood basalts engulfed and probably covered the rhyolite here, only to be exhumed with the help of the Columbia river. The evidence of caldera's, and other important geology, could easily be hidden within the undisturbed parts of the CRBG.
After watching this and listening to you trying to make a connection to Liberty I'm just wondering how the North facing slope South of Mission Creek and below the Liberty Beehive FS Rd. 9712 plays into this picture?
I live in Malaga and never knew about the Malaga slide. I see mission ridge from my house and can see the route of the slide. My property is between that route and the Columbia river and the land is filled with round, smooth river type rock. Can I assume it was once the path of the river, or maybe the great floods ?
First a question; Is Saddle Rock not a dike? Then an observation; I was thinking that the Wenatchee Valley bend was due to a mega flood. As the flood waters came down from the Okanogan ;^) and cut through the Swaukane gneiss it ran into the Saddle Mtn. rhyolite. This forced it to the ESE as it scoured out the valley, dropping the watermelons of the Pangborn Bar in the slackwater of the inside curve as it continued to level the under water surface of the fast moving outside of the curve. ??
I had that thought too! Thanks for adding some credibility to my question! It sounded like they were convinced that it was an extrusive flow. Perhaps a near surface “flow” of magma, a sill? I’ll quit now while, I’m already over stepping my knowledge base!😂
Nick. has anyone ever done any fluid dynamic simulation in this area. It seems like the water velocity moving through those narrow areas would be amazing.
I'm wondering if that giant landslide Nick talked about could have been triggered by one of or many of the ice age floods under-cutting the base area? It seems to coincide with that time!
44 million years? I have heard before that volcanos erode away after 2 million years. WTF! Also, being from the plains of Kansas, I get nervous whenever you guys are just a few steps away from possible death.
have you ever made a video about mission ridge?? looking just a couple miles west of you at saddle rock? its the high point for miles in every direction... I think it looks like a very old, weathered Mt St Helens.. you suggest the slide is only 20,000 years ago.... that wouldnt be volcano then -- but there seem to be spiky lava paths like pinnacles just south of you that i would think is a volcano- and saddle rock you are standing on is about the same -
@@laurafolsom2048 I’m up there a dozen times a year … it’s beautiful and certainly looks like something dramatic has to have been happening for a very long time to expose the bomber cliffs
Dr. Zentner, most of the roadside faces you show and I've seen elsewhere are fractured boulders; is it simply the dynamite? Of what integrity are the formations beneath? I hope this isn't too simple minded a question....
YOU SHOULD GO OVER TO "GOBBLER'S KNOB" JUST SOUTHWEST OF YOU KNOW. THE ROCK IS DIFFERENT, SOMEWHAT HARDER. i LIVE AT THE BASE OF THE MOUNTAIN AND HAVE CLIMBED IT MANY TIMES. YOU CALL IT "ROOSTER COMB", JUST NORTHERLY THERE WAS A TURKEY FARM BELOW THE MOUNTAIN.
Evidently not; he keeps saying it's the western-most extent of the CRB up through that valley. There is SO much geomorph going on in this area it's hard to keep it all straight in my elderly head. And every day it seems like a new discovery that causes everybody in the business to rethink what _really_ happened during the Eocene, why it happened, and in what order.
Hey geology peeps, this European Geosciences presentation really plugs some holes in the layperson's comprehensive understanding of the holistic techtonic/subduction/mantle processes. We found it incredibly useful in trying to get our head around the NW Pac situation. The stuff about geochemical inputs into climate and subduction- 👌🏼 th-cam.com/video/6OYbDrBvYQ4/w-d-xo.html
What a treat to wake up and find another 351 field trip ready to view. The volume of water that flowed past Saddle Rock is jaw dropping. Thank you for bringing us along.
The young man that loves “old rivers” is pretty sharp! 👍🏻
I have the pleasure of staring at Saddle Rock often.❤ love Chelan and Wenatchee, home for over 40 yrs.
Nick is teaching around the clock on a 24 Hour basis ~5AM PST, and he is uploading content! Thank You!

Great bunch of students and prof too! Thanks for taking us along with you on the field trip in such a majestic place!

Seriously enjoy this channel! The cascades look so interesting I'm thankful for these lectures. I'm from Kansas and love the geology around here!

Well that was pretty cool, it was almost like being there. So much to wonder about. And so beautiful.

Seems to be a thin line between Geology and Geomorphology. Such an interesting video. Watching from Georgia.

@dirkjefferson6202 I was talking to all or so I thought.
0:51, what a view!!!!
Looks like you guys hit the wildflowers timing just right!
You've a great group of kids, Nick. It's been great to see them both on video and live.
Wonder how many of Adrian's "friends" 🐍were keeping an eye on you guys!
Wow! Some more food for thought. Hope geologists find more evidence for that Okanagan flood theory. Maybe need to do more drilling through that tough cake....
Any ice age flood deposits would be on top of the basalt layers unless they were buried by recent landslides.
Hi Cindy! I was wondering if the rocks of the Pangborn Bar have been source identified.
@Poppageno no idea. From Nick's previous videos there are several papers out there that cover the Bar. I just did a Google on it, and there were some as well as a Nick video from a year ago. Most studies seem to be about the big erratics, but I am sure there should be some on the sediments as well.

Calcrete deposits are a cap to each mega flood…

Clearly seen on Manastash Ridge on Hwy 82/97 headed towards Ellensburg. I do wonder if there was a set of two ocean trenches 75 mya as our crystalline core was docking. One in front of the North American Craton the other in front of Siletzia. The CRB being deposited into these deep like a gutter filling with leaves. Rerouting rivers going to the ocean.

Could such a thing have happened with that big flood of Columbia river? This would be an unimaginably violent event, explaining the very high marks of flooding found there.

The Columbia river runs through so many of the stories of the state of Washington.
Perhaps it warrants your attention as a subject?
In new film Devotion,,,,Wenatchee Washington and surrounding mountains doubled for Korea during flying scenes.
Does your GEOL 351, Geology of the Pacific Northwest, class include all topics? Or are you focusing on geomorphology? Just curious.
First a question; Is Saddle Rock not a dike? Then an observation; I was thinking that the Wenatchee Valley bend was due to a mega flood. As the flood waters came down from the Okanogan ;^) and cut through the Swaukane gneiss it ran into the Saddle Mtn. rhyolite. This forced it to the ESE as it scoured out the valley, dropping the watermelons of the Pangborn Bar in the slackwater of the inside curve as it continued to level the under water surface of the fast moving outside of the curve. ??
I had that thought too! Thanks for adding some credibility to my question! It sounded like they were convinced that it was an extrusive flow. Perhaps a near surface “flow” of magma, a sill? I’ll quit now while, I’m already over stepping my knowledge base!😂
Nick. has anyone ever done any fluid dynamic simulation in this area. It seems like the water velocity moving through those narrow areas would be amazing.
I'm wondering if that giant landslide Nick talked about could have been triggered by one of or many of the ice age floods under-cutting the base area? It seems to coincide with that time!
What an informative video! Which camera are you using to record?
44 million years? I have heard before that volcanos erode away after 2 million years. WTF! Also, being from the plains of Kansas, I get nervous whenever you guys are just a few steps away from possible death.
Volcanoes erode, but some of their roots, caldera rims, pipes and plumbing, and hot ashy stuffs and breccias are more resistant.
have you ever made a video about mission ridge?? looking just a couple miles west of you at saddle rock? its the high point for miles in every direction... I think it looks like a very old, weathered Mt St Helens.. you suggest the slide is only 20,000 years ago.... that wouldnt be volcano then -- but there seem to be spiky lava paths like pinnacles just south of you that i would think is a volcano- and saddle rock you are standing on is about the same -
We ski there and I always take time for the amazing formations.
@@laurafolsom2048 I’m up there a dozen times a year … it’s beautiful and certainly looks like something dramatic has to have been happening for a very long time to expose the bomber cliffs
Dr. Zentner, most of the roadside faces you show and I've seen elsewhere are fractured boulders; is it simply the dynamite? Of what integrity are the formations beneath? I hope this isn't too simple minded a question....
YOU SHOULD GO OVER TO "GOBBLER'S KNOB" JUST SOUTHWEST OF YOU KNOW. THE ROCK IS DIFFERENT, SOMEWHAT HARDER. i LIVE AT THE BASE OF THE MOUNTAIN AND HAVE CLIMBED IT MANY TIMES. YOU CALL IT "ROOSTER COMB", JUST NORTHERLY THERE WAS A TURKEY FARM BELOW THE MOUNTAIN.
Lookout mt is CRB?
I would think it's Teanaway basalt from the numerous dikes!
Evidently not; he keeps saying it's the western-most extent of the CRB up through that valley. There is SO much geomorph going on in this area it's hard to keep it all straight in my elderly head. And every day it seems like a new discovery that causes everybody in the business to rethink what _really_ happened during the Eocene, why it happened, and in what order.
Hey geology peeps, this European Geosciences presentation really plugs some holes in the layperson's comprehensive understanding of the holistic techtonic/subduction/mantle processes. We found it incredibly useful in trying to get our head around the NW Pac situation. The stuff about geochemical inputs into climate and subduction- 👌🏼 th-cam.com/video/6OYbDrBvYQ4/w-d-xo.html
Hi!
HI Isabee! Welcome to Nick's Channel!
Let’s hope the MiCA dam doesn’t go and then the Revelstoke etc or your water mark is 150 ft + of the current view within 24 hours ! 😁💦🤷🏼♂️
The sage brush makes me feel like they are on purpose sentries doing their timeless guarding of what is their charge.
Q - which river valley or dry basin has the most chert rock available for north Columbia river water that needs to move ?
Looks like rhyolite that almost turned into pummice.
Thanks Nick!
