The mystery behind Colorado's only active volcano
HTML-код

- The Dotsero Crater in western Eagle County, is Colorado’s only active volcano. A new report from the United States Geological Survey lists it as a moderate threat to human activity.
Don’t worry, Dotsero is not expected to erupt again anytime soon, but it does give us a chance to explore the report, and this mysterious piece of Colorado geology a little further.
To help with the details, 9NEWS turned to Richard Busch with the Denver Museum of Nature and Science. He is an archeologist by expertise, but as an educator with the museum, he must be well versed in everything from anthropology to zoology.

9NEWS (KUSA) is located in Denver, Colorado.
It exists because the Rio Grande Rift from Leadville to Santa Fe is still is active, all around Dotsero has Super Hot Springs along a deep fault lines that extend along the Colorado River.
At Dotsero is like a punctuation mark between North and South.
The rise of core friction is not it alone. The Rift is still active.
The hole at the top of the volcano where the steam, ash, and lava escaped during the last eruption is not called a crater. It is called the caldera.
Not a caldera
It formed during the eruption not after when calderas typically form
that's not a caldera collapse. it was a maar explosion creator, huge difference that eruption would of only been a 2-3 not enough for a Caldera collapse + there is no present magma chamber nor was before most likely faulting that caused a basaltic intrusion of magma, to form the Cinder cone + Maar
It's most likely a maar, not a caldera. Mars often fill with water, if the climate allows for it. That water can then seep down to a depth where it can become superheated and boil, producing another phreatic eruption. No magma need be present for a steam eruption to occur.
It's not a caldera. It's called a Maar. Like the Kilbourne Hole near Deming, New Mexico. Same origin.
Not a magma chamber...but “just the core of the earth rising to the surface?” Umm...isn’t that what a magma chamber is?
not necessary, the deeper in earth you go, it constantly gets warmer. Temperature increases about 80°/mi into the earth!
Oooohhhhh a meteorologist reporting on geography and volcanology…………makes sense.
Not a lot of on-camera talent have studied or enjoyed science. Reporters tend to be journalists, writers, not science geeks. Would you rather the sports guy instead? Or the entertainment reporter?
Really, for this audience, enthusiasm is most important. Having a boring geology expert would be a disaster. And that's why you mention fake diamonds.
It's very much like being a school teacher.
Interesting video.
There’s not much to be afraid of here. Could Dotsero erupt in our lifetime? Sure it could! The chances of any potentially active volcano erupting in our lifetime are never nil. However, those chances are so small that it’s nothing to lose sleep over. Even if Dotsero erupted that immediate region is lightly populated. An eruption would directly impact relatively few people, and would probably shut down the interstate.
I love the reporter's enthusiasm.👍
Nicely done
These scientists say never again even when there’s been zero scientific research done to see if there’s any magma left.
Thank you Drone-9
Excellent gold spot
What’s it called?
What if La Garita woke up?
Yea
Here's 1 better what if all of them woke
It would be intresting to scientists if that thing Woke Up!
...Did the narrator mis-speak when he described Rich Bush as an "archaeologist" @0:47? Shouldn't that have been geologist or volcanologist?
From the description, "To help with the details, 9NEWS turned to Richard Busch with the Denver Museum of Nature and Science. He is an archeologist by expertise, but as an educator with the museum, he must be well versed in everything from anthropology to zoology."
I'm guessing that as kid, he visited museums often.
@@icollectstories5702 Thanks.
Not trying to scare anyone of course. But, a lot of faults are re-activating. Also, dormant or extinct volcanoes are waking up. Never say never. I saw that serious look and hesitation before the laugh.
i drove by this volcano a couple years ago and had the strangest experience, my cellphone wouldnt work at all, the temperature suddenly dropped and a thick layer of fog and mist appeared.. as soon as i passed the volcano it got warm and the sun came out
Weird man can I ask did you have an out of body experience or see volcano demons ??
Aliens.
Haha the mist can be explained because we have a gypsum plant that emits vapor every day, the Volcano is in Dotsero which has really bad cell service, and the temperature dropping well it is Colorado one minute it’s sunny and then its storming
This may be the only active one but half the mountains in Colorado are volcanoes LOL I live less than 40 miles away from two that I know of probably more
That can't be right. The Rocky Mountains were formed by tectonic plate action, not volcanic action. Besides Dotsero, there are only a small handful of volcanic mountains in Colorado, mostly located in the San Juan Mountains on the southern border with New Mexico. There is a small, 200 ft tall, object called Huerfano Butte in Huerfano County. It is the center cone of an extinct volcano that formed about 27 million years ago, long before the Rocky Mountains were raised. This object can be seen from I-25 between Pueblo and Walsenburg. As far as I know, "half the mountains in Colorado" are not volcanoes.
yes they are
@@badbiker666 actually google it. A volcanic field covered most of the rocky mountains and a majority of our mountains we know today including all of san juan are past volcanic activity where thr lava rock wore down
@@nozrep If you say so.
Last eruption around 4,150 years ago... which would be close to the time of Noah's flood. Which is very interesting considering the geologist stated that a large amount of water came in contact with deep molten lava to cause an eruption. "When Noah was 600 years old, on the seventeenth day of the second month, all the underground waters erupted from the earth, and the rain fell in mighty torrents from the sky." Genesis 7:11
There was no Noah's flood
@@williamedwards1528 Every knee will bow and every tongue will confess.
Phreatic explosions have been going on since the Earth's infancy, and they continue today. One of the largest explosions ever recorded was the phreatic eruption of Hunga Tonga Hunga Ha'apai in January, 2022.
Noah's flood is mythology. Noah's flood is a physical impossibility. Where did all the water to raise sea level to the height of the tallest mountain, come from? Where did it drain off to?
@@oscarmedina1303 Well, half of that question is explained in the passage above. "all of the underground waters erupted from the earth", indicating that all of the water came from within the earth. As to where all the water went, well I would suggest that it's probable that the water drained back to where it erupted from. We know there are huge underground aquifers all over the globe, and those are just what we know of. So, the biblical flood is not impossible at all. Maybe difficult to comprehend, but certainly not impossible. Beg God for the truth with an honest and sincere heart, and He will answer you in time.
La garita
Gouenji Shuuya
What about it?
La Garita, The Cat, One of the largest volcano eruption in ( Blew out horizonally) Colorado. LA Portal south side. Resurgent cone, and lava flows , tubes. Walking the road smell rotten egg . One of the eruption blew out into the current valley drive through dike into current crater. Currently active. East side of wilderness area, Creed west side. San Luis Valley North end of Rio Grande river. Fault. Volcanoes blow out east dammed north end of valley forming large under ground water , Lower valley had artisan wells for years..
victor thomas
What the fuck random ass shit are you talking about?
La Garita is an inactive volcano that has nothing to do with this video! Largest explosion in earths history, yes. Still has NOTHING TO DO WITH THIS VIDEO
It's been extinct for 26 million years.
Actually the great pyramids at Giza were already hundreds of years old when it last erupted.
It's not active it's dormant
🤔🤔🧐 seems to me sir that you're just an individual that doesn't know especially for there to be a hot spring there has to be a chamber of lava underneath that's how you get your hot springs so I discredit what you have to say
they are mush with crystals in there thats magma its alive theres no magma chambers its called mush. run for the hills.
Protip: Just not the hills along the I-70 corridor. XD
I hate to burst your bubble dude but the pyramids were built far later than that they're not four thousand years old there far older than just that.
You just contradicted yourself. You said they were built far later (more recently) AND also said they were far older.
