The Tieton andesite flows are confirmed as the longest viscous lava flows in the world! The exact reason why they were so long is complex, but heavily is related to its unusually high eruptive output (peaking at ~800 m^3/second). Another area of the world with unusually long lava flows is the Garibaldi and Garibaldi Lake volcanic complexes in Canada. There, a series of three unusually long dacite lava flows formed in the last 15,000 years, the longest of which is 20 km in length.
For anyone who wants to see what the lava and Andescite Columns look like, Nick Zentner just did a video on them a couple weeks ago! ua-cam.com/video/bkz-ziKjkt0/v-deo.html
It’s amazing how much detail you can get from reading the rocks. Sometimes I expect him to say something like “1.39 Million years ago, on a rainy Tuesday in February, ...”
I have long been listening to the UA-cam lectures, presentations and field seminars of Prof. Nick Zentner of CWU, Ellensburg WA. If I have found one thing outside Washington State, heck Northern California, Oregon, British Columbia, to Alaska, are all weird and unique. Lots to explore not just volcanic sites.
It’s where the waters of the great flood were bottlenecked into koolies during the end of the Silver Age. During the bronze age collapse a couple thousand years later the area burned with lava.
You can always tell when someone isn’t from the PNW the way he pronounced Yakima and a few other places mentioned lol. Anyways I’ve been watching your videos for a couple years now and love the videos. Thank you for covering all the stuff here in the Northwest.
Nick has both Geology 101 and Geology 351 complete courses available on line. He had to have them on-line available during the pandemic and opened them to the world. Participating students around the world from 9-year-old Patrick to 70 yo me took part in the conversation.
I've read about the Tieton volcano and those fantastic columns in an old roadside geology book on Washington. Mt Baker also has some really nice columnar andesite too. I never really thought about how unusual it was to have such a long andesite flow in the state.
Nick Zentner mentioned this in one of his lectures I think it was about the columbia flood basalts, but he didn't go very deep on the topic. I got very interested about it since, so having you explaining in detail is awesome. Thanks for this video!
Nick has been posting his lectures and field trips since the beginning of the pandemic, so you should be able to find more in depth information about them now. I've watched a couple of them, and they're FASCINATING.
I have to admit, sometimes I just click on this guy's videos for his comforting voice, and to get away from the craziness of the rest of the world and social media.
Thank you. Washington State has some of the most varied and fascinating geology in the world, from the accretion of the West Coast Terranes, to the Cascade active subductive volcanoes and back arc extinct hidden volcanoes, to the fantastic coolies that run through the Central state, and the volcanics in the East -- and that is just an overview. You could easily spend weeks covering all of these cataclysmic events.
On your ride over White Pass on HWY 12 many locations reveal the massive lava flows. Stop at the Oak Creek Ranger Station to admire the massive columns across the Tieton River. Many people even climb the columns in warmer weather.
Love the geology in this part of the world - there's always something unexpected! Thanks for such an informative vid! Btw - it's YAK-em-uh, not ya-KEY-ma 🙂.
And it's 'Tee-ton', not 'Ti-e-ton'. And a few others. VERY bad pronunciation on this one. But VERY GOOD information. I guess, maybe, perhaps we can just put up with it....
I used to live there: Yack-im-Ma and Cow-witch-ee and Nat-Cheese; gotta work on your native american names :-). 3:50 I can see my good friend's house. Again, I learned something-I had no idea that that even WAS a lava flow, much less the longest one. A suggestion for another local feature is Yakima canyon, which runs about 35 mile from north of Selah (see-LAA)(north side of Yakima) up to Ellensberg, WA. One of the more beautiful rugged drives you can take and REALLY fun on a motorcycle.
The Grande Ronde basalt flows would be another really interesting ancient volcano in the PNW to cover. Supposedly it was a singular volcanic feature which contributed a significant amount to the Columbia Flood Basalts, which is quite impressive to think about. Must've been a lot like an ancient Laki in the PNW.
Yes. There are impressive features in the walls of the Yakima river canyon north of the city of Yakima. I always drive WA203 to see the geology, eagles(often with babies), wild sheep and deer. Zenter's videos are great.
It’s not Yak-eema. It’s aama. I been rock hounding the area for a couple decades. I have the strangest conglomerates from those flows. There is a point in cowiche canyon where the andesite flow ends and basalt begins. The creek separates the two. Thanks for the video.
Well done my good man, that area is keen to my eyes. I have travled most of the Tieton, to about 10 miles past the dam. Even as far as over the ridge and south to Knife Blade Ridge. My dog and I crossed over on foot from Conrad Meadows, hi-lining the mounts well above Cirque and Surprise Lakes. It was a great trail head in the '80s. Seeing Mt Adams, St Helens and Rainier from one spot will never leave me. A few spots on the PCT were not safe for horses. Up at White Pass to Rainier to Stampede Pass is some of the best, and around Mt Baker. The Palasades are a wonderous sight as well.
I live in near Yakima, we can see many lava flows even today. We got over a mile thick layer of Columbia Flood Basalt that has many dozens of layers. Not sure which if Goat Rocks Lava or Flood Basalt came first, how many layers, or if both happening over time together and are intertwined. We have rock climbing because these flows. We also have the Yakima Fold Belts. Some rise nearly 2,000 feet. I live on the side of one and have a view of the 'Gap' where Yakima River carved it's way through the Basalt layers as it was thrust up to form Anticlines. The lava from Goat Rocks also contributes to the ridges, mostly on west side of town. I can look out and see many layers of Basalt that were cut by river. Also, the Yakima River Canyon is a spot where you can see dozens of individual layers. River is entrenched and has meanders. Yakima River was very old even before all the lava flows from multiple sources arrived here.
@@PedroDaGr8 great, thank you very much. I am lucky to live in such an interesting geology rich location. I can see the west flank of Rattlesnake Ridge from my deck and house. I can see across Yakima Valley at other ridges, rivers, creeks, etc. I have front row seat for the large landslide still moving one foot per week downhill.
Cool video! If you want another topic on long lava flows you could examine the Payun Matru volcano in Argentina, with its Pampas Onduladas flow which is the longest Quaternary lava flow.
If you are interested in seeing the site of these flows in more detail, you should check out Nick Zentner's video from last month here : ua-cam.com/video/bkz-ziKjkt0/v-deo.html. Nick is a Washington-based geologist and professor who regularly does "field trips" to some of the very interesting sites that are covered here on GeologyHub.
Hi, thank you for your very informative/educational video's. I like the format and the pace. My request is to have more information about Ngorongoro in Tanzania, as I have been in it. Thanks!
I have looked at those columnar formations many many times. I just rode by them earlier this year on my motorcycle. I look up at them every single time.
i love you content, but it is very clear you are not from the PNW based on pronunciations (Na-cheese, Yak em ah) other than that absoutely fascinating video. As a PNW geology nerd i love learning more about the surrounding country
I love your stuff, I watch almost everything you put out, but pretty pretty please look up Pacific Northwest place name pronunciation because none of them seem to make sense to people from outside the area. Yakima (pronounced YAK-uh-muh) was the one that got me this time. In other news, my partner grew up not far from Goat Rock, basically due west-northwest a ways.
Thanks for the vid, very interesting! I drive along the eastern side of hwy 12 quite often, especially during the winter to ski, so it is pretty cool to hear about how some of the terrain was formed. Hiking in the PCT into goat rocks is also extremely underrated in late August or early September as well (when there are less mosquitoes).
I really appreciate the work you put into these videos. That said, I do have one request. When showing photos and video describing the topic, I wish there were a symbol placed on the screen to indicate and confirm that what we are looking at, actually came from that very volcano. When using images from other eruptions throughout the world, the message begins to feel diluted or even confusing. For me, when learning about a certain volcano, I need to know exactly what images came from where...
I hate to be that guy....... But it's pronounced "Yeah-keh-mah" But always good to see you covering Eastern WA and the cascades, would love to see more on the Olympic peninsula. A real geologic oddity.
New to the channel and i know I'm a little late, but I've grown up Bonney lake, grand parents lived in Yakima. I've hiked through the goat rocks and been all up and down the tieton river. Always wondered what caused the cool looking rocks there! Great video
2:02 I was not aware that was a 12,000' volcano in the past. Wow. 3:10 This overflowing of that crater in only one hour is outrageous. 800 cubic meters per SECOND flowing.
I’ll have to keep an eye out for that; I drive to the west end of Yakima several times a month near where US 12 splits between heading to Natchez and Ellensburg.
I would love you to cover the Willamette River. Including, elk rock island and willamette falls and the willamette valley. The River did not carve the valley. It’s very interesting. During Missoula floods it flowed south instead of its normal northern flow which is also odd. Not that many rivers flow north in this manner.
I’m surprised that there hasn’t been any mention of this resource among rock hounds and abo tool makers. Has anyone searched the center for traces of kimberlite or pyrites? Are there any mining companies active nearby? I’m going to be a bit busy researching more questions about this area.
How are metal's concerned (gold silver lead, ...)? The best I can understand is sulfur is concentrated by mamga heating and then is mixed with water to form sulfuric acid at high temperature and pressure. As the acid works it's way towards the surface, it dissolves metals. (Hydrogen swaps with a metal ion?) As the mixture moves towards the surface it cools and the metals precipitates out. So, metals are often found in flow-vains. Please correct me and add more details.
Your pronunciation of Yakima as "Yuhkeema" made me want to tear my ears out. So easy to tell who's not from around here. I don't mean to be rude, but it hit me like a truck out of nowhere.
I live directly east of Goat rocks right where the map transitions from green mountains to desert. I've over looked Goat rocks many times from Darland mountain which has the second highest road in the state. From that vantage point I can see all the way to mount baker in the north of Washington to 3 sisters in central oregon. I had to think a bit to figure which drainage it took since the klickitat, cowiche, and ahtanum drainages were clearly impossible. I settled on the Tieton/Naches drainage. It would appear to be the only one with the correct elevation. Highway 12 traverses much of the length of this flow with many exposed columns. There are also some interesting flows and columns at the palisades before you come into Packwood which was from a large eruption 650000 years ago and also traveled a considerable distance from Goat rocks complex.
Is there a word to describe the reticulated pattern of dark patches and glowing lines that form when lava founders? It has a similar structure to the cells that form in salt flats, the mosaic of giraffe hair, mud cracks, and the light pattern like what you see at the bottom of a swimming pool. I know the latter is called a "caustic," but I don't think that word describes the pattern generally. Anybody have any ideas?
0:55 I doubt these flows would have been much longer regardless of their silica content. Silica is not the only thing that makes lava stiffer. Water dopes the same thing.
I live in Hayden, on the edge of the Rathdrum prairie. I know about the Lake Missoula floods, but I am interested in what exactly is filling the Rathdrum prairie and the surrounding areas from the floods. Thanks
1. In June of 1783, a large group of fissures opened in southern Iceland. 2. Large volumes of lava soon poured outwards at a rate exceeding 4,000 cubic meters per second. 3. The fissure soon propagated further, creating a 27 kilometer long fissure system which was all erupting at the same time. 4. This mini flood basalt like eruption was the largest effusive eruption to occur on the planet in the last 1,000 years. 5. It sent flows of basaltic lava up to 70 kilometers distant. 6. Other large volume eruptions have also occurred during the same timespan, and almost universally involved basaltic lava. 7. The reason for this is that the more silica a lava flow has, the more viscous it becomes. 8. Silica rich lava flows longer than 10 kilometers such as andesite or rhyolite are highly unusual and quite rare. 9. In the Cascade mountain range there exists a particular set of two lava flows which seemingly broke this rule. 10. There, from a peak in the Goat Rocks Wilderness, a 74 and 52 kilometer long andesite to borderline dacite lava flow advanced across the landscape. 11. This was the planet's longest known silica rich molten flow of material. 12. These two lava flows are known as the Tieton andesite flows, and stretch from Goat Rocks all the way to the edge of Yakima. 13. The edge of the longer and older andesite flow is most pronounced near Cowiche Creek. 14. These two massive lava flows were at one time thought to have originated from Mount Rainier by early geologists. 15. Instead, they originated from a completely separate volcano known as Goat Rocks.
New Zealand- Why does Ngarauhoe volcanoe have a steep cone like a viscous andesite eruption but its two neighbour's Tongariro and Ruapehu gentler slopes like a basalt cone? Cheers, Ben J
Hey I just moved near Ranier! Just FYI, natives pronounce is yak (like the animal) - i (like if) - mah (like your mother). I’ll have to go check this area out more
Local pronunciations are Yakima, and Cow-witch-ee. I used to work there Summers. Naches, where my Uncle Bob Allan lived, they pronounce Nah Cheese, NOT Naw Chez. These are NOT the original native American pronunciations, which are closer to what you might expect.
Please summarize the caldera movement (hot spot) migrating from northern California through Oregon then through to Wyoming? Do scientists have a good handle on the migration path? Might there have been more than one hot spot migrating from the west US coast north-eastward? I hope you will be able to cover this. I am mega-curious. Thank you.
I'm intrigued by your accent. I cant place where you're accent is from. Amazing video as always. Thank you for doing this. Btw, there is the theory that the Sierra Madre Occidental of Mexico is a large igneous province, but a silicic one (s SLIP, if you will). Have you already done a video on that or on regular LIPs?
Yak-eh-maw. That's how we say it out here. Or Crackima. Tho I prefer Yakompton. I've seen these structures but just assumed they were part of the badlands and never questioned it further. This was cool to learn, thank you. Hey 12 is a nice ride. You can drive south to Goldendale and check out a life size complete version of Stonehenge, overlooking the Columbia River. It's pretty freaking awesome. And quiet. The stones block all outside wind and noise, so it seems like the world begins and ends inside the ring. It's a trip. I recommend it. Duder who built it lost a decent chunk of his troop from WWUno, and he put this up as a memorial to the innocents and doughboys alike. I mean, I don't get it, how one thing there bridges to the other, but I can appreciate both his art and his loss even if I can't correlate them
Great video, actually recently discovered this ,and found it to be amazing that thick goey even blocky lava got that far ,timely subject thanks,please do girabaldi.
You said that the Tieton Andesite Flows filled the river valley, and over thousands of years, glacial and water erosion washed it away...where did it end up? Seems like a lot of material.
down stream obviously much if not the majority of the washed away material was likely carried away to the Pacific ocean once dislodged it doesn't take nearly as long to carry it to sea.
I REALLY appreciate and enjoy our videos, especially the hard data you include. I am finding your vids a good companion with MIcrosoft Flight Simulator.. you have explained several features I was wondering about (the impact crater in Australia NW), and given me plenty to explore. I am frankly finding it an awesome tool for learning more about Geology and specific features I see... eg The Great Escarpment, Salt Domes in Iran adn the obvious tectonics or that cauldera looking crater lake next to Manila... a bit of googling and i learn it is Taal... and has gone up since 'discovering' it. I was simming from Australia to Bora Bora and lost comms with the weather stations (real world weather).. curious, I did a google and found the Tonga Volcanoe had JUST gone up and was only reported in local news at the time andhadn't hit international news yet. Fyi without weather stations, you could not detect the eruption in the sim, but La Palma was very well modeled, I even compared the webcams with the sim. It showed only as cloud but at the right spot, density and with volcanic lightining. (comparison vid - ua-cam.com/video/SSdXj9h9HJs/v-deo.html ). Hey, I would really appreciate you covering the history around South Eastern Victoria (Australia) along the coast between Warnambool and Colac (the Red HiIl cinder cone fields). Most Aussies have zero clue about the volcanism here, and I know people living at the base of the major cinder cone near Camperdown (showing signs of growth or slippage) that have zero clue, I would love to know much more about it from someone with a clue like you! Keep up the wonderful work!
The Tieton andesite flows are confirmed as the longest viscous lava flows in the world! The exact reason why they were so long is complex, but heavily is related to its unusually high eruptive output (peaking at ~800 m^3/second). Another area of the world with unusually long lava flows is the Garibaldi and Garibaldi Lake volcanic complexes in Canada. There, a series of three unusually long dacite lava flows formed in the last 15,000 years, the longest of which is 20 km in length.
I'm guessing it's probably also related to having little to no gas in it, and slightly higher temperatures.
I'm beginning to get the concept that the geochemistry of magma is pretty complex and has everything to do with the tremendous variety of volcanoes.
For anyone who wants to see what the lava and Andescite Columns look like, Nick Zentner just did a video on them a couple weeks ago!

Agree! It's useful to see a photo of a feature being described, but is it the actual thing or something similar?
How about the Blue Rocks here in Pennsylvania? There's a campground nearby and nothing else like it around here. I always wondered how it formed.
Very compact bit of wonderful information. I would like to suggest doing a video of Mt. Shasta.

These types of lava flows make me think of some kind of living rock monster.
Going west from RimRock Lake, late in the day, the light off the basalt canyon walls is amazing scenery
I hate to be that guy....... But it's pronounced "Yeah-keh-mah"
But always good to see you covering Eastern WA and the cascades, would love to see more on the Olympic peninsula. A real geologic oddity.
The lava flows that created the Pacific northwest is amazing.. the volume the earth puked out is beyond belief...
New to the channel and i know I'm a little late, but I've grown up Bonney lake, grand parents lived in Yakima. I've hiked through the goat rocks and been all up and down the tieton river. Always wondered what caused the cool looking rocks there! Great video
Take a look at Calico Ridge, Henderson, NV. Crazy mixture of mineral deposits, lava flows, vent domes, and a wash.
Traveling around these flows is amazing; some of the most beautiful scenery in what is already one of the most diverse and beautiful states.
It is easy to assume that the source heating the magma may had a higher than normal temperature to increase the the longer flows.
I’d recommend going to Google earth to view the lava flows in Garibaldi Park. It’s quite interesting.
I just went on a field trip to look at these flows. Pretty cool rock
2:02
I was not aware that was a 12,000' volcano in the past.
Wow.
3:10 This overflowing of that crater in only one hour is outrageous.
800 cubic meters per SECOND flowing.
That Was Incredible Information' So complex! Thank You' and blessings always!🌎🌍🌏
Can you do the few (probably extinct) volcanoes in Croatia in the Adriatic? I think there is another extinct one on the mainland too.
I’ll have to keep an eye out for that; I drive to the west end of Yakima several times a month near where US 12 splits between heading to Natchez and Ellensburg.
I would love you to cover the Willamette River. Including, elk rock island and willamette falls and the willamette valley. The River did not carve the valley. It’s very interesting. During Missoula floods it flowed south instead of its normal northern flow which is also odd. Not that many rivers flow north in this manner.
There could well be longer/larger ones on the ocean floor. We just don't know enough about the ocean floor to be sure.
This is a really cool video, many thanks!
pretty neat, I've camped right there on the lava path near Teiton Lake!!
Tenerife also display very long phonolitic lava flows. Felsic lava is lighter and can be pushed farther
Also on the west side of white pass, there are beautiful column formations along the river and highway.
I’m surprised that there hasn’t been any mention of this resource among rock hounds and abo tool makers. Has anyone searched the center for traces of kimberlite or pyrites? Are there any mining companies active nearby? I’m going to be a bit busy researching more questions about this area.
How are metal's concerned (gold silver lead, ...)? The best I can understand is sulfur is concentrated by mamga heating and then is mixed with water to form sulfuric acid at high temperature and pressure. As the acid works it's way towards the surface, it dissolves metals. (Hydrogen swaps with a metal ion?) As the mixture moves towards the surface it cools and the metals precipitates out. So, metals are often found in flow-vains. Please correct me and add more details.
Your pronunciation of Yakima as "Yuhkeema" made me want to tear my ears out. So easy to tell who's not from around here. I don't mean to be rude, but it hit me like a truck out of nowhere.
Mt. Cireme on West Java on the north flank has a lava vent that traveled 5-6 km. That make me very curious.
I live directly east of Goat rocks right where the map transitions from green mountains to desert. I've over looked Goat rocks many times from Darland mountain which has the second highest road in the state. From that vantage point I can see all the way to mount baker in the north of Washington to 3 sisters in central oregon.
I had to think a bit to figure which drainage it took since the klickitat, cowiche, and ahtanum drainages were clearly impossible. I settled on the Tieton/Naches drainage. It would appear to be the only one with the correct elevation. Highway 12 traverses much of the length of this flow with many exposed columns. There are also some interesting flows and columns at the palisades before you come into Packwood which was from a large eruption 650000 years ago and also traveled a considerable distance from Goat rocks complex.
Could you do a report on the Granite State of New Hampshire. Why so much granite and whare did it come from?
Is there a word to describe the reticulated pattern of dark patches and glowing lines that form when lava founders? It has a similar structure to the cells that form in salt flats, the mosaic of giraffe hair, mud cracks, and the light pattern like what you see at the bottom of a swimming pool. I know the latter is called a "caustic," but I don't think that word describes the pattern generally.
Anybody have any ideas?
I thought your choice of “reticulated” was accurate enough for me!
0:55 I doubt these flows would have been much longer regardless of their silica content.
Silica is not the only thing that makes lava stiffer. Water dopes the same thing.
I live in Hayden, on the edge of the Rathdrum prairie. I know about the Lake Missoula floods, but I am interested in what exactly is filling the Rathdrum prairie and the surrounding areas from the floods. Thanks
1. In June of 1783, a large group of fissures opened in southern Iceland.
2. Large volumes of lava soon poured outwards at a rate exceeding 4,000 cubic meters per second.
3. The fissure soon propagated further, creating a 27 kilometer long fissure system which was all erupting at the same time.
4. This mini flood basalt like eruption was the largest effusive eruption to occur on the planet in the last 1,000 years.
5. It sent flows of basaltic lava up to 70 kilometers distant.
6. Other large volume eruptions have also occurred during the same timespan, and almost universally involved basaltic lava.
7. The reason for this is that the more silica a lava flow has, the more viscous it becomes.
8. Silica rich lava flows longer than 10 kilometers such as andesite or rhyolite are highly unusual and quite rare.
9. In the Cascade mountain range there exists a particular set of two lava flows which seemingly broke this rule.
10. There, from a peak in the Goat Rocks Wilderness, a 74 and 52 kilometer long andesite to borderline dacite lava flow advanced across the landscape.
11. This was the planet's longest known silica rich molten flow of material.
12. These two lava flows are known as the Tieton andesite flows, and stretch from Goat Rocks all the way to the edge of Yakima.
13. The edge of the longer and older andesite flow is most pronounced near Cowiche Creek.
14. These two massive lava flows were at one time thought to have originated from Mount Rainier by early geologists.
15. Instead, they originated from a completely separate volcano known as Goat Rocks.
According to OpenAI's chatGPT that is a 15 point summary of your video. :)
New Zealand- Why does Ngarauhoe volcanoe have a steep cone like a viscous andesite eruption but its two neighbour's Tongariro and Ruapehu gentler slopes like a basalt cone? Cheers, Ben J
I live like 600 feet from one of the Tieton Andesite places you highlighted lol
Hey I just moved near Ranier! Just FYI, natives pronounce is yak (like the animal) - i (like if) - mah (like your mother). I’ll have to go check this area out more
Local pronunciations are Yakima, and Cow-witch-ee. I used to work there Summers. Naches, where my Uncle Bob Allan lived, they pronounce Nah Cheese, NOT Naw Chez. These are NOT the original native American pronunciations, which are closer to what you might expect.
Excellently done ✅
Please summarize the caldera movement (hot spot) migrating from northern California through Oregon then through to Wyoming? Do scientists have a good handle on the migration path? Might there have been more than one hot spot migrating from the west US coast north-eastward? I hope you will be able to cover this. I am mega-curious. Thank you.
I'm intrigued by your accent. I cant place where you're accent is from. Amazing video as always. Thank you for doing this. Btw, there is the theory that the Sierra Madre Occidental of Mexico is a large igneous province, but a silicic one (s SLIP, if you will). Have you already done a video on that or on regular LIPs?
Could you make a video on Wilpena Pound and the surrounding Flinders Ranges in South Australia? There are some fascinating rock formations there.
Yak-eh-maw. That's how we say it out here.
Or Crackima. Tho I prefer Yakompton.
I've seen these structures but just assumed they were part of the badlands and never questioned it further. This was cool to learn, thank you.
Hey 12 is a nice ride. You can drive south to Goldendale and check out a life size complete version of Stonehenge, overlooking the Columbia River. It's pretty freaking awesome. And quiet. The stones block all outside wind and noise, so it seems like the world begins and ends inside the ring. It's a trip. I recommend it.
Duder who built it lost a decent chunk of his troop from WWUno, and he put this up as a memorial to the innocents and doughboys alike.
I mean, I don't get it, how one thing there bridges to the other, but I can appreciate both his art and his loss even if I can't correlate them
Does human activity influence occurrence of volcanic eruptions?
Great video, thanks for your work. Btw is Yack-imm-AH, not Yak-EEM-uh
Glasshouse Mountains, Qld, Australia. People may be interested?
would it be possible to find and extract gold or diamonds or other minerals from such flows?
How very interesting. I've driven 12 many times and recognize the cliffs along the river never knowing the geological history of what caused it.
Great video! And for more information search out Nick Zentner’s excellent lectures and videos covering the Geology of Washington State!

4:39 OMG that lava flow looks like it has lateral moraines, but of course it's not a glacier so they're probably called something else
Great video, actually recently discovered this ,and found it to be amazing that thick goey even blocky lava got that far ,timely subject thanks,please do girabaldi.
You said that the Tieton Andesite Flows filled the river valley, and over thousands of years, glacial and water erosion washed it away...where did it end up? Seems like a lot of material.
down stream obviously much if not the majority of the washed away material was likely carried away to the Pacific ocean once dislodged it doesn't take nearly as long to carry it to sea.
I REALLY appreciate and enjoy our videos, especially the hard data you include. I am finding your vids a good companion with MIcrosoft Flight Simulator.. you have explained several features I was wondering about (the impact crater in Australia NW), and given me plenty to explore. I am frankly finding it an awesome tool for learning more about Geology and specific features I see... eg The Great Escarpment, Salt Domes in Iran adn the obvious tectonics or that cauldera looking crater lake next to Manila... a bit of googling and i learn it is Taal... and has gone up since 'discovering' it. I was simming from Australia to Bora Bora and lost comms with the weather stations (real world weather).. curious, I did a google and found the Tonga Volcanoe had JUST gone up and was only reported in local news at the time andhadn't hit international news yet. Fyi without weather stations, you could not detect the eruption in the sim, but La Palma was very well modeled, I even compared the webcams with the sim. It showed only as cloud but at the right spot, density and with volcanic lightining. (comparison vid - ua-cam.com/video/SSdXj9h9HJs/v-deo.html ). Hey, I would really appreciate you covering the history around South Eastern Victoria (Australia) along the coast between Warnambool and Colac (the Red HiIl cinder cone fields). Most Aussies have zero clue about the volcanism here, and I know people living at the base of the major cinder cone near Camperdown (showing signs of growth or slippage) that have zero clue, I would love to know much more about it from someone with a clue like you! Keep up the wonderful work!
