Yellowstone News and Information

By  Yellowstone Volcano Observatory   May 20, 2024 Is Yellowstone Overrated? As a Disaster Movie Subject, Maybe . . .  Many people regard Yellowstone as an exceptional place that merits only positive superlatives. But in much of the broadcast, streaming, and popular media it has an outsized reputation as a global catastrophe waiting to happen. Let’s do some fact checking to see which view is more realistic.  Yellowstone  Caldera  Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Dan Dzurisin, emeritus geologist with the U.S. Geological Survey. Few would argue against Yellowstone being “super”—both a splendid natural wonder worthy of careful stewardship, and a super-sized volcanic system capable of correspondingly large eruptions with potentially far-reaching impacts. As the latter, it has inspired any number of disaster shows and movies, not unlike menacing asteroid...

By  Yellowstone Volcano Observatory   April 15, 2024 Monument Geyser Basin: A Unique Vapor-Dominated Thermal Area in Yellowstone National Park  Just south of Norris Geyser Basin is a little-visited thermal area called Monument Geyser Basin. The “monuments” there are unique in Yellowstone’s above-water hydrothermal areas and resemble the “black smoker” deposits found at the bottom of the ocean. Yellowstone  Caldera  Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Pat Shanks and Lisa Morgan, research geologist emeriti with the U.S. Geological Survey.        Sources/Usage: Public Domain.  View Media Details View of Monument Geyser Basin in Yellowstone National Park, with one of the  silica  spire "monuments" (from which the basin gets its name) in the foreground.

Ferdinand Hayden And The Founding Of Yellowstone National Park By  Yellowstone Volcano Observatory   October 30, 2023 Geologist Ferdinand Hayden directed the first scientific exploration of Yellowstone in 1871, leading directly to the founding of the world’s first national park in the following year. Hayden’s noteworthy achievements in science and conservation, however, are clouded by his views of indigenous people.     Yellowstone  Caldera  Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Cole Messa, Ph.D. student, and Ken Sims, Professor of Geology and Geophysics, both at the University of Wyoming. Yellowstone—the " land of the burning ground "—has been known to indigenous people for at least 11,000 years. In fact, in 1805 the  governor of Louisiana Territory described a map drawn on a bison hide by an indigenous American showing a “volcano” on the Yell...

Which Is more Hazardous to Tourists? Wildlife or Hot Springs? Yellowstone  Caldera  Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Michael Poland, geophysicist with the U.S. Geological Survey and Scientist-in-Charge of the Yellowstone Volcano Observatory. Yellowstone National Park is home to an array of “charismatic megafauna”—for instance, elk, bears, bison, wolves, and other large mammals.  And as the term “wildlife” implies, these animals are, well, wild.  Yellowstone National Park requires all visitors to stay at least 100 yards (91 meters) away from bears and wolves, and at least 25 yards (23 meters) away from all other large animals, like bison and elk. Despite these well-publicized warnings, stories of people approaching too close to animals, and sometimes being injured, appear every year. Sources/Usage: Public Domain.

Hypoliths: Life thriving under the beach-white sinters of Yellowstone's hydrothermal areas While most attention is given to the hot springs, geysers, fumaroles, and mud pots in Yellowstone’s hydrothermal areas, there are lessons just beneath the surface about how life might have taken shape on Earth billions of years ago. Yellowstone  Caldera  Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Dr. Jeff Havig and Professor Trinity Hamilton, researchers in Plant and Microbial Biology and Earth and Environmental Sciences at the University of Minnesota. A s one walks along the boardwalks in one of the many hydrothermal areas in Yellowstone National Park, there is a feast for the senses—the rotten egg smell of hydrogen sulfide, the blasting spray of geysers, the bubbling and boiling water in hot springs, the hiss of gas escaping fumaroles, the low thumping of mud pots, and the dazzlingly bri...

Acknowledging Annie: How research and monitoring get done in Yellowstone Yellowstone  Caldera  Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Michael Poland, geophysicist with the U.S. Geological Survey and Scientist-in-Charge of the Yellowstone Volcano Observatory. Better knowledge of Yellowstone’s past volcanism and current behavior is key for understanding the potential for  future hazardous activity, like volcanic eruptions, strong earthquakes and hydrothermal explosions .  Data collection, however, must be balanced against the impact on Yellowstone National Park,  much of which is managed as a wilderness .
