Latest News On Yellowstone National Park
Although it is commonly believed that the river was named for the yellow rocks seen in the Grand Canyon of the Yellowstone , the Native American name source is unclear. Great Falls of the Yellowstone, U. Army detachment commanded by Lt.
What would happen if the Yellowstone supervolcano actually erupted?
US Geological Survey If the supervolcano underneath Yellowstone National Park ever had another massive eruption, it could spew ash for thousands of miles across the United States, damaging buildings, smothering crops, and shutting down power plants. It’d be a huge disaster. A super-eruption would be horrific — though also pretty unlikely But that doesn’t mean we should all start freaking out.
The odds of that happening are thankfully pretty low. One occurred 2. And despite what you sometimes hear in the press, there’s no indication that we’re due for another “super-eruption” anytime soon.
In fact, it’s even possible that Yellowstone might never have an eruption that large again. Even so, the Yellowstone supervolcano remains an endless source of apocalyptic fascination — and it’s not hard to see why.
In Septembera team of scientists published a paper in Geochemistry, Geophysics, Geosystems exploring what a Yellowstone super-eruption might actually look like. Among other things, they found the volcano was capable of burying states like Wyoming, Montana, Idaho, and Colorado in three feet of harmful volcanic ash — a mix of splintered rock and glass — and blanket the Midwest.
That much ash could kill plants and animals, crush roofs, and short all sorts of electrical equipment: Ash, ash, everywhere An example of the possible distribution of ash from a month-long Yellowstone supereruption. So I talked to him further about what we actually know about the Yellowstone supervolcano, what its eruptions might look like, and why the odds of disaster are low.
What is the Yellowstone supervolcano? National Park Service Lurking beneath Yellowstone National Park is a reservoir of hot magma five miles deep, fed by a gigantic plume of molten rock welling up from hundreds of miles below. That heat is responsible for many of the park’s famous geysers and hot springs.
And as magma rises up into the chamber and cools, the ground above periodically rises and falls. The vast, vast majority of Yellowstone eruptions are small On rare occasions throughout history, that magma chamber has erupted. The vast, vast majority of those eruptions in Yellowstone have been smaller lava flows — with the last occurring at Pitchstone Plateau Glacier National Park To Great Falls Mt 70, years ago.
But the reason why Yellowstone gets so much attention is the remote possibility of catastrophic “super-eruptions. That’s enough to bury Texas five feet deep. Helens eruption of The last of those, at Yellowstone Lava Creek, ejected so much material from below that it left a mile-bymile depression in the ground — what we see today as the Yellowstone Caldera: Location of Latest News On Yellowstone National Park Yellowstone super-eruptions National Park Service It’s worth noting that Yellowstone is hardly the only supervolcano out there — geologists have found evidence of at least 47 super-eruptions in Earth’s history.
That triggered a dramatic 6- to year global winter and according to some may have nearly wiped out the nascent human race. On average, the Earth has seen roughly one super-eruption everyyears, although that’s not an ironclad law. So what would a Yellowstone eruption look like? Let’s reiterate that the odds of any sort of Yellowstone eruption, big or small, are very low. This would likely be precipitated by a swarm of earthquakes in a specific region of the park as the magma made its way to the surface.
A super-eruption is capable of sending ash many thousands of miles Now, in the unlikely event of a much bigger super-eruption, the warning signs would be much bigger.
It could take weeks or months for those earthquakes to break up the rocks above the magma…

Planned to be completed by , in honor of the 50th anniversary of the founding of the National Park Service, Mission 66 construction diverged from the traditional log cabin style with design features of a modern style. Phase 1 will begin on Monday, May 18 at p. He observed at least one geothermal area in the northeastern section of the park, near Tower Fall.
