A calf moves with a herd of bison in Lamar Valley, Yellowstone National Park.
It turns out that the video of black bears chasing tourists in Yellowstone National Park is less a case of a protective mother and her cubs and more a case of a frightened bear trying to get away from gawking tourists who trapped them.
Geophysicists have discovered a second, even more massive magma reservoir feeding the Yellowstone supervolcano, providing researchers with the most comprehensive picture yet of the volcanic system beneath the park.
Taken just a few days after the official start of spring, this photo of the Porcelain Basin Hot Springs (named after the milky white mineral deposit) almost looks like the national park is steaming off winter in favor of spring.
Decades ago, the Morning Glory pool at Yellowstone National Park was a gorgeous deep blue. But because tourists have thrown coins, rocks, and trash into it for years, the spring has now turned into a sickly yellowish green. Now, a new optics study is shedding light on the pool's unfortunate change of color.
Because every time there's a new viral Bigfoot video, we can't stop ourselves from watching it, skepticism be damned. This one, at least, contains some lovely views of Yellowstone National Park, where the geysers are majestic and the buffalo roam ... and maybe Sasquatch (keep your eyes on the trees) do, too.
The Fountain Paint Pots in Yellowstone National Park are named for the colorful muds produced by the oxidizing iron in the mud, the natural result of hot springs. In November 2014, a light dusting of snow both revealed the topography of the area and made the steam rising from the ground clear and eerie.
Montana's Yellowstone hosts America's largest herd of bison, and one of the only remaining wild populations left. But now some of their almost 5,000-strong herd is ready to be adopted out.
Someone, somewhere, decided that Yellowstone was in a period of unusually high geologic activity and facing major road closures and evacuations, and therefore was in danger of imminent eruption. This is all so ridiculously untrue, I hesitate to even use the "debunkery" tag because it's hard to believe it needs…
The cast and crew of Transcendence talk the science of their dowloaded-brain movie. There are wild rumors from the set of Christopher Nolan's Interstellar. And Agents of SHIELD is still reeling from last week's revelations. Plus, news about what new shows we'll be seeing in the fall. Spoilers now!
Yellowstone National Park sits on top of a giant volcanic caldera, or an earthen cap that covers a huge reservoir of superhot liquid rock and poison gasses. Large parts of the park were formed in previous eruptions, the most recent of which happened about 70,000 years ago. Now, the floor of the caldera is rising, and…
A single volcanic eruption wiping out life on entire continents isn't exactly a cheery thought, but at least we had the mild comfort that it would take as much as 200,000 years for one to erupt. Yeah, about that...
We can't predict a volcanic eruption more than a few days or months in advance. But one of the most devastating eruptions in human history could give us a huge boost in predicting the next massive volcano.
Supervolcano eruptions are the most devastating natural disasters on the planet, unleashing destruction that can level entire continents and kick off new ice ages. We've long struggled to understand what causes these unimaginable eruptions... but now, there might be an answer.
The wolf pack seems like the perfect example of how unity can provide strength, of how fierce and often vicious hunters can work together for the common good. Unfortunately, that's a big lie. Turns out many wolves are freeloading bums.
Yellowstone National Park boasts dozens of geysers and broiling eruptions. But they're nothing compared to the massive volcano that bubbles beneath the park, and could unleash a world-altering blast. Check out these images of the megablast-in-waiting.
Dozens of nearly-imperceptible mini-earthquakes have made Yellowstone National Park tremble over the past few days - they might be early warning of an eruption so huge it buries half the U.S. under hot ash.
