The Time When Volcanoes Repeatedly Dammed the Gila River in Arizona

[@GeologyHub]

It was fun to cover one of the closest volcanic systems to where I live in Arizona. From a geological perspective, they are largely overshadowed by mid tertiary ignimbrite flare up dacite and rhyolite volcanism which created a number of ore deposits.

[@temosofthecommunistrepubli2637]

What was the biggest volcano eruption to happen in Greece?

[@BFjordsman]

One of my favorite rock hounding places is right out there east of safford, lots of agatized fossils. Gila river is awesome 👍

[@timothyknorr8183]

I live in Phoenix and love rockhounding out near saddle mountain. Would love if you did a video on that area and why so much chalcedony later formed in the porous rock. Thanks for the great videos!!!

[@Jake-qz5uf]

I have lived in Arizona my whole life and never knew that there once was volcanoes just west of Phoenix! Thank you so much for making this video, now I want to see these extinct volcanoes for myself! 😄

[@jaydmjay499]

I lived in Surprise AZ for some time and never knew there was an extinct volcano within an hours drive. Thanks for sharing!🙏

[@StuffandThings_]

A series about lava dams would be incredibly interesting. If I recall correctly, there's a handful of extant lava dams around the planet, like in Wudalianchi, Garibaldi lake, and Lake Disappear in New Zealand.. Plus, all the historic ones around the American west. They're super interesting and unique features and I'd love to hear about more of them, considering most are incredibly obscure.

[@Dragrath1]

The prevalence of historic lava dams in the American west or other dry places could be an artifact of arid relatively flat environments better displaying the features without significant vegetation or elevated erosion due to glaciation etc. destroying them so I wonder how thoroughly surveyed other parts of the world are for these? The Sunda shelf seems like a good place to look for that kind of feature given the ancient ecology the highly active volcanism, albeit quite a bit more explosive with examples such as Samalas Krakatau Tambura or Toba etc. but surely there are a number of less explosive events for every VEI 6+. In fact I remember reading about the resolution to a longstanding mystery in trying to identify the source crater for a tektite rain event in southeast Asia where it was ultimately identified that the impact crater was buried beneath basaltic lava. It seems the meteor had hit/ the Bolaven volcanic field which later infilled the ~17 km crater. If a impact crater of that size can be hidden by lava I imagine it is far easier for a river to be blocked off after all they have a smaller cross section.

[@charlesroeckeriv6226]

I live in Yuma AZ and we've got a bunch of extinct mini-volcanos all over the area. It's really cool to see light-colored rock and sand with contrasting fields of black lava rock. Google Maps is a great tool to spot where they are from above.

[@oscarmedina1303]

Thank you for posting. I drive through this region quite often and wondered about the all the geology. The Sentinel rest stop on Interstate 8 is a great place to park in order to explore the surrounding lava field.

[@wiredforstereo]

I think your standard explanation of the explosion crater has gotten much more concise and effective.

[@carnivoreRon]

A beautiful photo of quail at the end of the video. Thanks for all the information you give us.

[@peterf.229]

[@cyankirkpatrick5194]

Can't get enough of these, even though sometimes they don't cover eruptions which can be a good thing. Thanks for keeping us updated.

[@fbiagentmiyakohoshino8223]

i live in phoenix arizona and know of some volcanoes here but had never known these exist. good to know now

[@kesomon]

At the point of the video where you were explaining why the volcanic field existed there, the subtitles displayed before the voiceover, so I read it as 'the thing is happening due to existential forces', not extensional, until the voiceover corrected me. Lol at volcano having an existential crisis.

[@Iconoclasher]

I heard on another channel the Superstition Mountains have an interesting volcanic history. It would be interesting to hear your take on it

[@lol_iyoutube]

[@garycrockett4477]

Thanks for taking the time to post. I find these fascinating. I could be wrong, but I thought I heard you mispronounce Palo as in Palo Verde. It's a short a (like cat), not a long a. Again, thanks!

[@AlmarPostma]

Any chance of an episode on Fogo volcano in Cape Verde? Last erupted in 2014. Or an episode on Surtsey in Iceland? It even has an eruption type named after it.

[@郑颍]

@geologyhub it is often claimed locally that the state of Victoria in Australia has the third largest volcano field with more than 400 volcanoes. I am a physicist not a geologist but wonder if this is indeed so.

[@GeologyHub]

This sounds about right. The volcanic field stretches from just north of Melbourne to the border of South Australia (last eruption was 2900 BCE Mount Gambier). That is why Gambier has a series of lake filled explosion craters. You are referring to the Newer Volcanics Province. I have an older video on this.

[@郑颍]

@@GeologyHub They are great places to visit :) They are two hours west of melbourne. In fact the lava plains run up to the western suburbs of Melbourne

[@garypalmer2066]

In northern Arizona there is a volcanic field with around 700 volcanic cones. One called Sunset Crater erupted 1000 years ago. Displacing the local native humans.

[@bigrooster6893]

I definitely wouldn’t classify this volcano as extinct because volcanic fields have the longest duration without eruptions.

[@paulkurilecz4209]

very much enjoy your videos.

[@AndisweatherCenter]

Awesome video! Those volcanoes are tiny!

[@peterf.229]

They aren’t as small as they seem when you are on foot or climbing up/down surfaces

[@rastus666]

The Colorado river in the Grand Canyon had numerous small lava dams over the ages.

[@garypalmer2066]

Actually there was a lava flow that dammed the Colorado River at a point on the northwest rim where Vulcans Throne is now at Toroweap that backed the river farther upstream than the present day Glen Canyon Dam does with Lake Powell. Lava Falls on the Colorado River is caused by rocks in the stream beds and high on the south wall is a volcanic plug of basalt rock. It took perhaps millions of years for the lava dam to erode allowing the Colorado River to once again flow psst on downstream.

[@JimInYamaguchi]

Fascinating!

[@rjgoniea]

It'd be interesting to see your take on the mid-continent rift that was partly responsible for the shape of Lake Superior and the flood basalts forming Isle Royal and the "spine" of the Keweenaw peninsula of Michigan. I've already read and watched a lot about it but it might be interesting to your other viewers.

[@Dakotaraptor_Official]

Those are some pretty small volcanoes

[@XcRunner1031]

I did not know AZ had much in the way of volcanoes. That stretching feature of the crust is very interesting.

[@garypalmer2066]

Northern Arizonas highest mountain is the San Francisco Peaks a strato volcano that is 12,637 ft high. Nearby is Sunset Crater that last erupted 900-1200 years ago. And over 600 other volcanic cone volcanoes to the north of the San Francisco Peaks. And Mt Baldy in southeast ce teal Arizona on the Apache Reservation where the Little Colorado starts. There's Shiprock in NW New Mexico, a volcanic core.

[@Dovietail]

New River, AZ geology? I read in a geological survey report that we have some of the oldest rocks in the world here as well as some of the youngest. Is this true?

[@ice9594]

I live about 10 mi. north of New River, AZ. Someone told me the small mountain there, which is visible to the East side of the I-17 highway near the New River exit, is called the New River Volcano & it was once active. It would be interesting to know.🤔

[@peterf.229]

Maybe New River Mesa? It’s a lava flow , if I remember right about 25 mya . As for older rocks , I live in Black Canyon City and oldest rocks are in the Bradshaw mtns about 2 bya.

[@machinegunhippy]

[@peterf.229]

Are you talking about Gavilian Peak?

[@TheDanEdwards]

You mention that crustal extension is what has led to deep faults in the crust, allowing magma to reach the surface. However, you did not explain _why_ there was a magma chamber there to begin with. Is this yet another phenomenon that we are going to attribute to the "roll back" of long-ago subducted Farallon plate?

[@davec9244]

thank you

[@JustaReadingguy]

I would like to understand the volcanic history of the Villa Grande, west of Los Alamosa NM. The calderia has a 40 miles diameter. That seem big. Also did the Rio grande rift play a part of its formation.

[@deadgoon2170]

Would Sentinal peak be an off shoot of the volcanic field?

[@chanklasychonies]

Have you done one on Picacho Peak? Is it an ancient volcano that was covered by the "Tucson Mountain Chaos"?

[@aprildenham4730]

Pichacho peak was long considered nsidered to be a volcanic neck, and looks every bit the part. Recently thinking shifted as proof came to light that indicates that it is really a lava flow, that subsequently was nearly overturned to 90 degrees give or take

[@laraleepn]

I heard of rivers that are stolen by other rivers which would be an interesting topic. I believe the Provo river in Utah did this to the Weber River at some time in the past.

[@anthonyloconte7835]

@@peterf.229 is that the reason?

[@NielMalan]

Is the mechanism behind groundwater-powered volcanic explosions the same as the firefighter's nightmare, BLEVE (boiling liquid expanding vapour explosion)?

[@labaccident2010]

It’s the pressure generated when the water becomes steam, so…maybe?

[@peterf.229]

The cause is when water is heated rapidly and flashes to steam. Steam takes a larger volume than water and so this causes pressure . I think that a steam explosion is similar to a BLEVE .

[@NielMalan]

@@peterf.229 The reason I'm asking is that it's not clear to me that magma can actually boil the volume of water required to produce that size of explosion at the rate required to cause an explosion. Or, alternatively, can groundwater intrude at a high enough rate to cause an explosion, rather than a normal steam vent? If it's the equivalent of a BLEVE, then it makes sense to me: an enclosed volume of water is superheated by the magma. When the overlying rock cracks and lets the pressure drop to atmospheric pressure, then the whole mass of water is suddenly boiling and turns to steam in an instant. If the overlying rock can't withstand the pressure, the result is a cratering explosion.
