Thx! I love your appreciation and curiosity for nature! “Even the rocks will cry out!” is more than poetic metaphor. It’s the truth! Thank you for helping us understand what the geology is trying to teach us!
Do you this is a weird comment but please understand as an educated man. I have had lots of issues in the last three years, as we all have. For me, my wife left me at the very beginning in January 2020. It's relevant to your videos because you became one of my amazing RUclips friends. I have no crazy ideas about being buddies with people on RUclips, but I have a deep appreciation for the intimate value of RUclipsrs like yourself that express ideas, through their own personality. All of you, and you are one of the top ones, have been a sustaining friendship in general for me. I am so grateful, and I have learned much in the process! That is pretty fucking bitchin. With your great videos, and my acknowledgment of this amazing science, we turned lemons into lemonade. You probably do it for thousands of people and that is bitching. But you did for me too. For free, dude working at a market in Southern Cal . I just told my sister yesterday, who resides in Washington and Oregon alternatively, I told her then I know more about Washington geology than my own Southern California geology, and that's a true story brother
Hey brother, one of the many things that I dig about you, is that you are a romantic. Now that word, doesn't necessarily imply intimate relations type stuff. You're an educated man so I figure you didn't know that it also refers to folks who are in spired by human emotion, to the point of influencing their thoughts and activities. Yes I am very logical and uptight, but I can also be groovy. I think that goes for many of you geologist cats. So I've only heard a few seconds but you are a master, if you don't know it. These casual videos can really bring a person like me in. I am interested in the geology and I also have stressors in life and happy tendencies. Your calm and thoughtful, reflective analysis, sometimes very planned out which I appreciate as being a science strength,All of these things make your videos great to me
Love that you are chasing down a topic that is not solidified, putting puzzle pieces together where they could fit, building a story that we dont quite understand yet.
What a beautiful valley and evening. Thank you for taking us on this gorgeous field trip. It means even more knowing the geographic history of it. The connection through time is mind boggling. That we presently walk on an ancient Earth. Thank you for all your teachings and videos. Ya gotta love it!
Thanks, professor! Very interesting! Yes, you've mentioned much of it before, but for a non-geologist such as myself, repetition helps to reinforce what you're talking about with these terraces. It wasn't long ago that I would have driven through a landscape like that and not given it a second glance. Your personalized tour really helps to bring it to life! Always looking forward to seeing whatever it is you have to show! See you at the next one!
Brought to you by Birkenstock. You are awesome man. Please keep being you, trust me. I am a 53-year-old man living in Southern California, who was turned onto you by a lady who works on ferry boats in Alaska! She used to live in Washington and she found one of your old high 90 rocks videos, then posted it. From there I watched the entire series of course, and then I subscribe to every channel of yours that I could. You are spreading enthusiasm for geologic science, and great facts and knowledge about said science for all of us metal type enthusiasts!!!!Thank you man
The geology is fascinating, but geez, just the beauty of the place is hard to get past. Looks like it was filmed around Magic Hour; the greens are exquisite.
I used to deliver your newspaper a few years back, i remember watching you do live classes as i walked past and whenever i got home i would start watching. Im glad that you're still making videos after all the years
Dear Professor Nick on the rocks! Hubby & I have been fans since we first found you on RUclips a few years back. Usually watch on the TV so I forget to go to my phone so I comment -although I do register a 👍 after each vid. I have been meaning to just drop in to tell you, “we love you too!” It just does our hearts good when you say it to your audience. We get your sincerity. Thanks for all you share. This was a beautiful walk & very interesting. We have family in EBurg so we hope to make it over next fall with hopes we can drop in on a lecture of yours. Or catch you on a field trip at Hood Canal where we live. Thank you! ❤️
OH! Every video adds to understanding, thank you Nick. The light showed the terraces beautifully, and the valley, too. It seems daunting to map the Okanogan area, but this was, so it's possible. I love that you spontaneously thought to show us. Joy! 🤗
I can't thank you enough for your work on RUclips. I have an amateur interest in geology that lead me to these inspiring videos you put together. Especially these field trip format. Being able to see what you're talking about helps me appreciate geology even more.
Breathtaking. Thank you for so many wonderful views and explanations. Again, this makes so much sense when I can visualize what you are talking about. So good evening and we love you too.
Lovely scenery! Love this time of the day and the clouds add a very nice touch to the background. I studied geology in Illinois and we sure had plenty of glacial features to explore. Glacial erratics in the middle of farmers fields we’re very common. Moraines, and evidence of the old Lake Chicago were evident in many places. Washington glacial features and remains are so much more interesting with the great elevation changes that are evident. The terraces are very interesting.
Thank you Nick for another wonderful clip of your area. You mentioned that you might be repeating yourself over certain things. Well this ole girl needs to be told many many times! I have watched your various series' more than once and things are starting to sink in this brain. I am not making a study or thesis of this but it is just great to learn. Oh I wish I could find more about Britain's geology. I know Iain Stewart made a series on the BBC and have watched him a few times but we need more over here. Oh, and just the rambling walks are fantastic too for the scenery :) Keep up the great work. I love it!
"I hope it's clear to you why I have lived here for 30 yrs".....message received, sir. Thanks for keeping this old man interested in geology. It's been 44 yrs since I flunked out of the geology curriculum at SIU at Carbondale, IL. I have watched your videos for quite some time now. Thanks again.
Welp Nick, I just wanted to say thanks! Watching your video's has sent me down an ice age rabbit hole. I live in West Virginia in the Kanawha River Valley, which was indirectly impacted by glaciation. The Pre-Illinoian Glaciation changed the course of the Ohio and Kanawha Rivers, because of the formation Lake Tight and Lake Monongahela, which were caused by the glaciers blocking their paths and becoming so deep they breeched ridges. These breeches became their modern flow paths and in the case of the Ohio River, reversed its flow. Truly amazing. There is one thing I haven't found is how these lakes interacted, because they existed at nearly the same time.
What a terrific teacher you are. You bring me back to my Geology 101 course over 50 years ago while a student at the College of Forestry Syracuse NY. With a little knowledge about the different types of rock and how they are formed, earth processes one can understand the story of how the uniquely beautiful state that we live in came to be. Your videos are great and I look forward to many more
Thank you so much Professor Nick, for pointing out the obvious and knowing so much about geology that you can present an obvious cause and effect. I enjoy walking with you, seeing through your eyes, trying so very hard to learn to take it in and remember. I appreciate that you point out places near and far. and let your mind and knowledge come together for our benefit. I am never disappointed in your content or dialogue. You are a force on this earth for good, I can't thank you enough for teaching me. You have had an enormous impact on how I view an ordinary scene. I find myself longing to gather a few of those coblestones you showed us once. it actually made my heart best faster. ha ha. Thank you from the bottom of my heart.
Thank you Nick for taking us along on your fascinating journeys through these fascinating landscapes of the Pacific Northwest. Your love for geology, nature, people, teaching and the PNW radiates through the screen and warms us all. And I for one love you for that. Warm greetings to you and your family from Dreischor in The Netherlands.
It’s very clear to me why you’re still intrigued, fascinated and enamoured with the geology of your state , so much going on in such a dynamic landscape. I live on the east coast of Australia and our geology is also fascinating you just have to look far and dig deep to find it, love watching your videos Nick! All the best Jules
Excellent video, great light. My interpretation of that environment is that the valley was a lake. The glacier pushed debris into and and across the lake at its highest water level. Both sides of the valley were contiguous. Subsequently, the lake fell creating the lower terrace. The terraces identify ancient lake levels. The first and highest terrace was then incised by the river, dividing the once contiguous terrace. If the terraces have downward angles, they are deposited as typical moraine. The perfectly flat terraces would have to be deposited in water, AT the water level. Every table indicates a water level at a specific time, within a draining environment. This environment is uncanny in its similarities to my area of the Okanagan in BC. I tend to write these as I watch and it is good to hear your musing tend to match my own. Thanks again Nick, I love learning from you.
I've actually been to Cle Elum (more than a decade ago, for someone's wedding). It's a gorgeous evening, and the terraces are evident. I'll never be able to blithely cruise through Washington on vacation without thinking about geology again.Thanks! Nothing wrong with some repetition when your audience contains - as in this case - novices and amateurs.
Beautiful Nick! I have never been exploring around Ellensburg. Chuckle at your patience! I see the flats/terraces! There are some really nice beauties there! It’s all fascinating.❤️😍
It’s amazing to see the geologic and glacial history of the area. But this also displays graphically how much time there is between intermittent glacial periods.
Hahahaha, this is great! Your enthusiasm and curiosity are inspiring, and I hope generate some post grad field work. Dang, I was in that area yesterday...need to return. Those rocks are cool!! Thanks for another joyful outing! 🤗💕👏
Catching up today! What a gorgeous evening and great lighting to see these different terraces. The Yakima River valley has been a busy place. Thank you
I think I spotted the Umtanum ridge Pass area coming from Yakima. Love that cutoff from yakima and down the final hill into Ellensburg on a clear night. Have drove all over that area to harvest veggies during the season,, many times,,and flew over it for years at 11,500 feet on the way to Northern Idaho as a child.
The flowers and the rolling hills are exquisite! I’m from Mid Florida and I’ve become so skeptical about terraces made by bull dozers to use the soil for toll roads
I live on the west side and always found it interesting, that all the rocks, look like they went through a tumbler, River Rocks. Also spent time in the Grand coulee area and there are Warehouse size boulders, just sitting on top of farmland. One doesn't have to be educated to understand the obvious.
Nick and the Zentherds....question Any effect of folding/faulting/the big squeeze on moraines/flats? The flats sort of, or "may" remind some of us of the 'headlands" along the Ca. coast.
On the Marysville side there appears to be an alluvial plain. I can use my single speed bicycle as long as I stay in this delta region, but climbing up to the east I need the multi-speed bike.
Thanks so much Nick!!!! Another question I have had with all the amazing questions and information you have shared: what is the biggest question that you have had to which you have discovered solutions?
At time stamp11:29 in the center of the frame, there is a large volcanic pillar on the south bank of the river. I have noticed it several times while driving east on Highway 10. How could this pillar of basalt survive the alpine glaciers? It stands higher that the lowest flat further to the left.
The lowest 'benches or flats are the youngest structures. I f the valley was previously filled full of glacial/ ice sheet deposits the lowest deposits would be the first moved in. Then the lowest, newest structures are in the oldest deposits? I'm not questioning this. But I sense that I am missing something.
Cool topography, I am struggling with the idea that certain younger flats are lower elevation. Due to valley filling , makes sense…. Just odd because usually glaciers wipe out previous older topography, crazy, water makes huge factor, and lesser glaciation making a new level. Wild stuff. Thank you sir
If the younger valley glacier is smaller/narrower than the older, it will leave its terraces at a lower level, without destroying the older, higher ones. Some glacial valleys have more terraces than this one.
@@p.d.nickthielen6600 It's discernable in some of the smaller lobes of the most recent continental ice sheets as they paused while retreating, but much more typical of valley glaciers.
I have often wondered about the taraces between Brewster and Wenatxhee, the explanation from my collage days was they were deposited by ice age floods. This never made sense to me. I always thought they must have come down from the north. Glacial out wash is a better explanation. I have also thought that the source of the water that formed Mosses coulie must have come from the Okanogan.
It sticks out as you walk around this valley without a wisp of wind blowing the ridge line is full of still modern wind turbines. The placement of wind turbines should indicate strong and fairly constant wind. Such strong and constant wind should be indicated in the land scape with obvious signs of wind erosion and strongly effect the types of plants that can grow and how they grow.
I live in the Columbia Basin in eastern Washington. It is a windy region, but not constantly so. Most of the aeolian landforms have been covered since the last ice age with shrub-steppe vegetation and/or grassland, as seen in this video, which limits further development. The arid climate is the primary factor in the regional native flora and fauna.
I love your videos and some of them remind me of a trip that I took many years ago thru Yakima River Canyon. Just a small sugestion I dare to make: please fix the focus on whatever camera you have - its even possible with an iPhone. Whenever zu point zu something with your finger, the focus changes to the hand and then back. That could be avoided by fixing the focuspoint - mostly to infintiy anyway for horizons. Greetings from Switzerland, Peter
Patiently waiting for his next call for a pop-up lecture. If I can keep the drive and the hike inside of 5 hours from where I live I'm gonna try my best to be there.
I am close by, 2 hours from Nick. I live at one of the places he talks about all the time. In fact that is why I started following him. My youngest daughter, sister and brother all got degrees from Central - Business (darn) and teaching. My problem is that I have old age issues. I can not walk very far. Also my hubby is still working so can only do weekends. ( I cannot drive 🙄). I really wanted to do Maryhill and Drumheller Channel but we had camping plans. Maybe someday. Sorry I have been really chatty today.
@@grammiebythelake5246 No worries. I live in Vancouver, so it's not a _terrible_ drive but one in which I'd wanna put up for the night if I were to do it. And like you, my age limits the distance I can hike. But hopefully he'll pick a spot for the next one that I can plan for. Last month it seemed like every time Nick set one up for a particular date and time I couldn't go because of dr. appts. You know how those are to move; so I wound up having to stay put. Still hoping I can make it for the next one.
I have watched a lot of your videos. I just happen to like rocks. I live in New England and it is pretty much ubiquitous and very very old. There’s just not a lot to see. But I enjoy your videos very much. I realize they are localized in Washington and that is in very new landscape geologically. I have a question. Do you think that the terracing that you see in such a large swaths at the higher elevations, do you think that as the river dig deeper it possibly erodes more material? Would that be because the valley gets narrow and therefore water flow becomes more intense or do you think that the younger rocks or just more durable. I’m not even sure if I ask that question correctly. It just seems strange that rivers get narrower and narrower the older they are. I would think that the rock that the water flows upon should be more compressed and even harder to erode.
If I was to go and give an answer to my own question I would suspect that the weight and compression of the stone at the bottom of these rivers has been released and therefore makes them more fragile.
It would be interesting to do a statistical analysis of the particle sizes in the various terraces, which seem like they would be remnants of old braided outwash plains, and see if any trends emerged in the relative velocity of the waters that deposited and re-worked the materials. Did the flow volumes vary over time, with higher flows in the past and more recent flows with lower volume and current speed. Can any interpretation be made about the stream gradients, either increasing or decreasing with the growth of Menashtash ridge and the other ridges? Could Ice Age floods have aggraded the stream beds down stream and lowered the gradient by depositing sediments that have since been removed and increasied the gradient of the Yakima River? There are a bunch of similar videos from New Zealand on the “Out There Learning YT channel, vignettes of local features, and striking geologic features.
Instead of Old Whitey, I was borrowing a name from Gary Randall, a photographer here in Oregon. He calls his rig the PPV... Photo Pursuit Vehicle. So, when I saw your rig I thought, 'ah, there's the GPV.' Geology Pursuit Vehicle.
Is it possible that the whole valley wasn't eroded after each glacier but the subsequent glacier rode and eroded the previous creating its own terrace? and the last one just followed the valley/river leaving the last terraces to be eroded by the river. At least that's the way it looks to me viewing the video and having driven the road and fished that same spot.
One would be matching those same elevation terraces by the soil characteristics and parent material characteristics. No problem. Did so many times in my soils career in glacial landscapes throughout the Pacific Northwest.
In the 2 million old ice age/glacial history: regional snow fall and glaciation in the southern latitudes came first. Then build up at the 'poles', within the arctic (and Antarctic) ice sheets sliding south over all. Could the out-wash of 'retreating' ice sheets flowed over ice filled valleys resulting in these benches on the margins?
Isn't standing liquid just about the only physical situation that produces so nearly horizontal surfaces? If so, we have to imagine a still water situation that delivers a wide variety of rock sizes, unsorted. I think that implies a long lasting lake carrying a massive sequence of floating ice that carries all sizes of rocks, that are dropped wherever the ice can freely float. That would fill the lowest areas last, as the higher areas blocked the movement of ice rafts. These terraces have to be sprinkled into place, not bulldozed.
Don’t confuse flat and horizontal. These terraces are flat (no relief) but not horizontal (they have a slope, albeit pretty minimal) so this implies movement of water, not standing water. The size and arrangement of the material is also more consistent with moving water (streams, outwash)
@@jeromelesemann1855 I’m having difficulty wrapping my mind around the fact that the lower terraces are the youngest. It looks as if the terraces on top of the lower ones were overlayed on the bottom ones. Is there evidence that the upper terraces have been cut away from the tops of the lower terraces?
@@paulbugnacki7107 if we accept that the terraces involve water movement and erosion, then overlaying a terrace on top of another would require that the entire course of the river 'climb' to progressively higher elevations. Although aggradation (sediment build-up) does occur, it would require that the entire valley be filled with sediment to reach the upper elevations - this would essentially amount to burying the lower terraces and we would not see them. The simplest explanation is that the lower terraces from after the higher ones and are therefore younger.
You described the flat formations as "glacial outwash" terraces, which is logical since the great portion of the valley is composed of glacial outwash. Could they also be considered as former "lake" terraces? Could successively younger lakes have been formed as the Yakima River eroded downward through the glacial outwash, but impacted by glacial advance and retreat and the impounding of lakes by glacial moraines that created the silted terraces now being farmed for produce?
Someone said you can find a certain gemstone here that's only found here! Some blue stone? worth something like $250 per carat? No one seems to talk about this. But their is one video where a lady claims their are rare blue gems only found in one area and happens to be on her ranch property formed from the volcano many years ago!
found a new way to slowly wake up, although your voice almost puts me to sleep ! Similar to my Algebra 1 teacher, I had 63 years ago! lol - but her lectures were boring, as opposed to your geology episodes!

It's clear. That final shot had the light just right. It helps to see the terraces in different locations and lights.

This is very interesting Nick
I just hope you go deeper into this and talk about what kinds of rocks that where deposited on the terraces
Going from a dangerous motorcycle ride in Mexico to peaceful Washington.
I'll be glad if Nick gets to guide Noraly through Washington Cascades!
I think I spotted the Umtanum ridge Pass area coming from Yakima. Love that cutoff from yakima and down the final hill into Ellensburg on a clear night. Have drove all over that area to harvest veggies during the season,, many times,,and flew over it for years at 11,500 feet on the way to Northern Idaho as a child.
This is fascinating. And sublime, surreally gorgeous scenery.
Grew up in Ellensburg. Lived about 3 miles from the Pautzkee's on Look Rd. Lots of great geology in Washington State.
The flowers and the rolling hills are exquisite!
I’m from Mid Florida and I’ve become so skeptical about terraces made by bull dozers to use the soil for toll roads
Hello, Prof. Zentner and yes, Birkenstocks -- you've got to love them! Alas, not the best footwear to be hoppling over erratics 😉
Thanks Nick! Insane terrain there.
Wow Nick . You picked a beautiful time to film this. Colors saturation textures .
Beautiful! Loving the flower/boulder combo.
❤ glacial til deposits.
Thank you. i finally understand the logic of the oldest layers on top !:-)
💜🙏⚡️
hugs Nick, Thanks!
I live on the west side and always found it interesting, that all the rocks, look like they went through a tumbler, River Rocks. Also spent time in the Grand coulee area and there are Warehouse size boulders, just sitting on top of farmland. One doesn't have to be educated to understand the obvious.
Nick and the Zentherds....question Any effect of folding/faulting/the big squeeze on moraines/flats? The flats sort of, or "may" remind some of us of the 'headlands" along the Ca. coast.
On the Marysville side there appears to be an alluvial plain. I can use my single speed bicycle as long as I stay in this delta region, but climbing up to the east I need the multi-speed bike.
Thanks so much Nick!!!! Another question I have had with all the amazing questions and information you have shared: what is the biggest question that you have had to which you have discovered solutions?
Thanks Nick.
At time stamp11:29 in the center of the frame, there is a large volcanic pillar on the south bank of the river. I have noticed it several times while driving east on Highway 10. How could this pillar of basalt survive the alpine glaciers? It stands higher that the lowest flat further to the left.
Lovely scenery.
Love your videos. Tks!
Wing Central, no smoochin fries. The best👍
Thank you for explaining why youngest on bottom. Gnite Professor :D
The lowest 'benches or flats are the youngest structures. I f the valley was previously filled full of glacial/ ice sheet deposits the lowest deposits would be the first moved in. Then the lowest, newest structures are in the oldest deposits? I'm not questioning this. But I sense that I am missing something.
Cool topography, I am struggling with the idea that certain younger flats are lower elevation. Due to valley filling , makes sense…. Just odd because usually glaciers wipe out previous older topography, crazy, water makes huge factor, and lesser glaciation making a new level. Wild stuff. Thank you sir
If the younger valley glacier is smaller/narrower than the older, it will leave its terraces at a lower level, without destroying the older, higher ones. Some glacial valleys have more terraces than this one.
@@leestamm3187 ok I get it but it kind of blows my mind. I assume this can only be true of alpine glaciers?
@@p.d.nickthielen6600 It's discernable in some of the smaller lobes of the most recent continental ice sheets as they paused while retreating, but much more typical of valley glaciers.
@@leestamm3187 thank you
And I love your work!
I have often wondered about the taraces between Brewster and Wenatxhee, the explanation from my collage days was they were deposited by ice age floods. This never made sense to me. I always thought they must have come down from the north. Glacial out wash is a better explanation. I have also thought that the source of the water that formed Mosses coulie must have come from the Okanogan.
It sticks out as you walk around this valley without a wisp of wind blowing the ridge line is full of still modern wind turbines. The placement of wind turbines should indicate strong and fairly constant wind. Such strong and constant wind should be indicated in the land scape with obvious signs of wind erosion and strongly effect the types of plants that can grow and how they grow.
I live in the Columbia Basin in eastern Washington. It is a windy region, but not constantly so. Most of the aeolian landforms have been covered since the last ice age with shrub-steppe vegetation and/or grassland, as seen in this video, which limits further development. The arid climate is the primary factor in the regional native flora and fauna.
Beautiful. I really enjoyed our walk Nick. And, I'm not even tired.. I think I could go for another one. Hmmmmmmm, which video will be next?
I love your videos and some of them remind me of a trip that I took many years ago thru Yakima River Canyon. Just a small sugestion I dare to make: please fix the focus on whatever camera you have - its even possible with an iPhone. Whenever zu point zu something with your finger, the focus changes to the hand and then back. That could be avoided by fixing the focuspoint - mostly to infintiy anyway for horizons.
Greetings from Switzerland, Peter
Last week Visited Wallowa Lake which is said to have the best example of a terminal moraine… but no obvious terraces there.
Good Evening
Professor Nick, wish I could do all the walks and hikes you do. Some day if you have an event with a short walk.
Patiently waiting for his next call for a pop-up lecture. If I can keep the drive and the hike inside of 5 hours from where I live I'm gonna try my best to be there.
I am close by, 2 hours from Nick. I live at one of the places he talks about all the time. In fact that is why I started following him. My youngest daughter, sister and brother all got degrees from Central - Business (darn) and teaching. My problem is that I have old age issues. I can not walk very far. Also my hubby is still working so can only do weekends. ( I cannot drive 🙄). I really wanted to do Maryhill and Drumheller Channel but we had camping plans. Maybe someday. Sorry I have been really chatty today.
@@grammiebythelake5246 No worries. I live in Vancouver, so it's not a _terrible_ drive but one in which I'd wanna put up for the night if I were to do it. And like you, my age limits the distance I can hike. But hopefully he'll pick a spot for the next one that I can plan for. Last month it seemed like every time Nick set one up for a particular date and time I couldn't go because of dr. appts. You know how those are to move; so I wound up having to stay put. Still hoping I can make it for the next one.
What an amazing video, what camera did you use?
If you are ever up in Oroville. Hit me up. I look right into the cascade ranges just out my front door.
How many different ice ages can be detected in the Yakima and Ellensburg areas? It seems there are several.
I have watched a lot of your videos. I just happen to like rocks. I live in New England and it is pretty much ubiquitous and very very old. There’s just not a lot to see. But I enjoy your videos very much. I realize they are localized in Washington and that is in very new landscape geologically. I have a question. Do you think that the terracing that you see in such a large swaths at the higher elevations, do you think that as the river dig deeper it possibly erodes more material? Would that be because the valley gets narrow and therefore water flow becomes more intense or do you think that the younger rocks or just more durable. I’m not even sure if I ask that question correctly. It just seems strange that rivers get narrower and narrower the older they are. I would think that the rock that the water flows upon should be more compressed and even harder to erode.
If I was to go and give an answer to my own question I would suspect that the weight and compression of the stone at the bottom of these rivers has been released and therefore makes them more fragile.
There's at least 400 to 500 ft of mudflows on the east backdrop behind Naches
🙏✌🏽👏
It would be interesting to do a statistical analysis of the particle sizes in the various terraces, which seem like they would be remnants of old braided outwash plains, and see if any trends emerged in the relative velocity of the waters that deposited and re-worked the materials. Did the flow volumes vary over time, with higher flows in the past and more recent flows with lower volume and current speed.
Can any interpretation be made about the stream gradients, either increasing or decreasing with the growth of Menashtash ridge and the other ridges? Could Ice Age floods have aggraded the stream beds down stream and lowered the gradient by depositing sediments that have since been removed and increasied the gradient of the Yakima River?
There are a bunch of similar videos from New Zealand on the “Out There Learning YT channel, vignettes of local features, and striking geologic features.
Instead of Old Whitey, I was borrowing a name from Gary Randall, a photographer here in Oregon. He calls his rig the PPV... Photo Pursuit Vehicle. So, when I saw your rig I thought, 'ah, there's the GPV.'

Is it possible that the whole valley wasn't eroded after each glacier but the subsequent glacier rode and eroded the previous creating its own terrace? and the last one just followed the valley/river leaving the last terraces to be eroded by the river. At least that's the way it looks to me viewing the video and having driven the road and fished that same spot.
One would be matching those same elevation terraces by the soil characteristics and parent material characteristics. No problem. Did so many times in my soils career in glacial landscapes throughout the Pacific Northwest.
Question: Since we have a succession of terraces, is there also a succession of terminal moraines down valley?
In the 2 million old ice age/glacial history: regional snow fall and glaciation in the southern latitudes came first. Then build up at the 'poles', within the arctic (and Antarctic) ice sheets sliding south over all. Could the out-wash of 'retreating' ice sheets flowed over ice filled valleys resulting in these benches on the margins?
Isn't standing liquid just about the only physical situation that produces so nearly horizontal surfaces? If so, we have to imagine a still water situation that delivers a wide variety of rock sizes, unsorted. I think that implies a long lasting lake carrying a massive sequence of floating ice that carries all sizes of rocks, that are dropped wherever the ice can freely float. That would fill the lowest areas last, as the higher areas blocked the movement of ice rafts. These terraces have to be sprinkled into place, not bulldozed.
Don’t confuse flat and horizontal. These terraces are flat (no relief) but not horizontal (they have a slope, albeit pretty minimal) so this implies movement of water, not standing water. The size and arrangement of the material is also more consistent with moving water (streams, outwash)
@@jeromelesemann1855 I’m having difficulty wrapping my mind around the fact that the lower terraces are the youngest. It looks as if the terraces on top of the lower ones were overlayed on the bottom ones. Is there evidence that the upper terraces have been cut away from the tops of the lower terraces?
@@paulbugnacki7107 if we accept that the terraces involve water movement and erosion, then overlaying a terrace on top of another would require that the entire course of the river 'climb' to progressively higher elevations. Although aggradation (sediment build-up) does occur, it would require that the entire valley be filled with sediment to reach the upper elevations - this would essentially amount to burying the lower terraces and we would not see them. The simplest explanation is that the lower terraces from after the higher ones and are therefore younger.
You described the flat formations as "glacial outwash" terraces, which is logical since the great portion of the valley is composed of glacial outwash. Could they also be considered as former "lake" terraces? Could successively younger lakes have been formed as the Yakima River eroded downward through the glacial outwash, but impacted by glacial advance and retreat and the impounding of lakes by glacial moraines that created the silted terraces now being farmed for produce?
Any of this affected by the Missoula flood, or are we to far east and or north?
Someone said you can find a certain gemstone here that's only found here! Some blue stone? worth something like $250 per carat? No one seems to talk about this. But their is one video where a lady claims their are rare blue gems only found in one area and happens to be on her ranch property formed from the volcano many years ago!
Time for an overall big lecture on the ice age in Washington
A guy from Wisconsin questioning his experience with glacial deposits seems a bit strange
Glacier terraces are scattered all the way down the 410 highway.
"Well kid, what you're looking at is glacier barf." - my dad years ago pointing out glacial features
NICK, ANY LINKS TO LIDAR OF THAT AREA?
found a new way to slowly wake up, although your voice almost puts me to sleep ! Similar to my Algebra 1 teacher, I had 63 years ago! lol - but her lectures were boring, as opposed to your geology episodes!
