When people think of Arizona, they tend to not think of volcanoes. Yet, the state contains two active volcanoes, one of which recently erupted in the town of Flagstaff. The volcano I am referring to is called the San Francisco volcanic field, which contains a wide variety of vents not seen elsewhere in the United States. It contains a stratovolcano, explosion craters, cinder cones and more! Scientific evidence just recently re-dated one of its many young lava flows, meaning that this volcano has erupted twice in the last 10,000 years. This video will discuss this volcano, the latest scientific development, and discuss the newly dated SP Crater.

I was all too excited to make this video. I just knew that SP Crater had to be younger than its "reported" 70,000 year old age :D. Thus, the San Francisco volcanic field is a bit more active than we initially thought.

@clousetechworkshop7597 2 года назад

I'm so happy you did, I commented on your earlier video on this volcanic field. I had heard recently that SP-crater was younger than previously thought. I'm stoked you were able to confirm that. I love your videos and never miss them. Keep up the amazing work. I know your schedule might be packed but have you ever investigated the geology regarding Stoneman Lake in AZ? I used to spend a lot of time in that area and that lake basin remains a mystery to me, and the consensus as far as I can find online is mixed. Having seen the lake myself and knowing the area I am still hoping it's an impact crater, the raised rim and back tilted layers make it really seem like it is. But I've also read that it could be a phyrratic type crater or even a sinkhole. It would be cool if you have access to any information that would be more definitive. It's definitely a feature that doesn't fit in with the surrounding landscape.

The first time I visited the Grand Canyon, I drove there from Las Vegas. I could see what I now know to be the San Francisco Volcano Field and, probably, San Francisco Mountain as I drove up Rte. 64 towards the Canyon. I could tell immediately they were volcanos, but this video fills in a lot of gaps. I will definitely have to book a trip to Flagstaff sometime and really explore the volcanos.

I was also fortunate in traveling a lot of the lower 48 with geologists (my undergrad is geology). Three different times I took several week long car trips (twice just by myself). My memory has stored hours and hours of the most wonderful videos in my head (this was mostly before real video cameras). With what I have visited in the US a lot of it on backroads and some on dirt roads :) and I know how other people travel - I remember something Charles Osgood wrote 'The interstate highway system is a wonder - it allows you to go coast to coast while seeing nothing'. I am right now remembering the night I pulled into craters of the moon idaho in October after dark, pitched a tent and spent damn close to the coldest night I have ever had. Then I woke up to discover that I was setting on a raw fresh lava flow complete with pumice scoria and lava tubes, it was just like waking up on the moon.

I lived in Phoenix for many years and raised my son in the desert. We would go to Flagstaff twice a year to cool off in the summer and to enjoy a weekend of snow in the winter. Until I moved to Flagstaff in 2008, I had no idea the San Francisco peaks were part of a volcanic field! We lived there for 13 years and about 2 miles from Sunset Crater at one time. I experienced 2 earthquakes and never felt comfortable living so close to the Peaks. Back in the desert again!!

@ValeriePallaoro 2 года назад

Using Potassium/Argon dating is where the problem lies; it's upward limit is about 100,000 years before the present, after which finding enough Argon to date any closer time frame is problematic. So trying to date anything younger than that is impossible. You're so right, too, the cinder cone and the lava flow look more recent, so the date should have been suspect right from the start. Good bit of geology in this video. Thanks so much!

I just learned that a young, 24-year old, geologist went missing from his job-site in Arizona in June and little media attention was paid and little was done to find him. As a fellow geologist, it really upsets me. He was so young, and possibly this was his first job, so tragic! Ours is the most dangerous profession of all and we hope we can count on lifesaving search and rescue services if we need them. Apparently, his disappearance has strong evidence suggesting murder, the crash of his car was staged. His name is Mr. Cawley-Robinson, and by googling his case, a petition can be signed to help find him at last. I did, and hope all other geologists and rockhounds will. I’m sorry I couldn’t add the link, being an older geologist lacking the computer savvy of the young ones, I don’t know how.

Yes it is impressive just how many cones are in AZ. I live in Apache County Arizona between St John's/ New Mexico border and due north of Springerville on the high mesas looking south southwest. The road we locally call the St John's/Springerville connector runs by several cinder cones and right through a lava flow that is unmistakable in appearance. I figured that they were still fairly young as they are just now starting to grow vegetation and no Junipers have grown on them at all yet and they grow on everything. The highway that connects Springerville to Show Low is also through thus type of setting but much older all of it is the Northeast side of the White mountain range and is beautiful country and very empty country only a handful of us live out this way. Our small ranch is approximately 7300 ft above sea level and I watch the sun set over this region every evening from my living room window and it is stunning.

Only possible if magma is in the volcano. It sort of makes its own space as it intrudes into the crust.

If I recall correctly, they have few methods to measure size & depth of magma chamber via seismic waves like those geologists mapped several magma chambers with one deep reservoir under Long Valley Caldera. Although there is newer technology from Japan in 2011 or later, has surfaced to have ability to see magma chambers or conduits via cosmic radiation (muon rays mainly), IIRC.

I didn't know that Mt. San Francisco was a volcano! Driven past it numerous times. Interesting!!

According to a seismologist I talked to the volcano located in woodruff az was the last to erupt in az about 275 years ago

I did enjoy your video very much good job I'm doing it I must say the title had me excited to think that somehow there was a volcano going off here in the US because I know once you getting ready to go off

What’s amazing is there we’re probably Native American alive living in the area when this volcano erupted.

Wonder if any more will erupt in recent times?

In comparison, cinder cones in very wet areas in Hawaii can get covered by vegetation far faster and don't look as fresh as this even though they're younger.

Can you please discuss the formation of Tucson? I've heard it is basin and range but also that it is a volcanic caldera. Also Signal mountain known locally as A mountain is basaltic but not from a volcanic eruption. I'm thinking it might have been a volcanic fracture like in Iceland. I'm very interested in your opinion

Can you make a video about Olympus Mons on mars?

Lots of confusion between SP and what I thought was Sunset Park (sunset crater). I saw sunset crater once in the mid 60's. Time to go.

I wander what would happen if a bunch of people went into the crater of the volcano and just started digging

Cape Verde eruption prediction was spot on. Hopefully many lives were saved as such.

I'd name it "little squirt". Would be a great backdrop for a sifi movie, "Giant Fireants" !

How do volcanologists know how tall volcanoes were before they blew off their summits in eruptions?

@jasonp9340 2 года назад

I never new there was volcanoes in Arizona. Now Im curious if there is any in my state of Illinois.

"ERUPTION THREAT" . . . I'm not sure that would exactly be a great topic, but maybe ? Before Mt. St. Helens blew there was at least one guy living on the side of the mountain who refused to move, despite geologists warnings . . . he disappeared in the blast. Some years ago there was a, by then elderly, couple (both life long volcanologists) who "disappeared" into the haze while studying lava flows (I've wondered if it was an accident or how they decided to "go out"? Visiting Kilauea Nat'l Park and observing a slow moving surface flow, a ranger approached warning "sometimes lava flows can contact pockets of buried organics that have become gases, causing an explosion which can be very dangerous! When the ranger was asked "are you saying it is very dangerous and I must leave or it is very dangerous and I should leave?" the ranger replied "I'm saying it is very dangerous and I am leaving" and he walked away. B-) RISK = Risk x Time (window of exposure) .
