The roads less traveled in the Greater Yellowstone Ecosystem
What values do these road-less areas offer for science, for recreation, for wildlife? As public land owners, we all shape the future of the Greater Yellowstone Ecosystem and other wild landscapes.
Caldera systems—a worldwide family that is more than just Yellowstone!
Did you know that there are similar caldera systems spread across the globe? And many of these are far more volcanically active than Yellowstone!
Yellowstone's shadow
The lack of any basalt in Yellowstone caldera—the existence of a magmatic "shadow"—is good evidence that the rhyolite magma chamber is still at least partially molten.
Seeing Yellowstone in stereo: The importance of monitoring Yellowstone's thermal areas from aircraft photos
Images acquired using inexpensive cameras from airborne platforms can be used to monitor surface changes in thermal areas over a variety of spatial and temporal scales.
Yellowstone's rock record—rolling through much of Earth's time
Yellowstone National Park contains rock formations that span over half the Earth's 4.6-billion-year lifespan!
The December 2019 hydrothermal explosion at White Island (Whakaari), New Zealand, and its lessons for Yellowstone
Hydrothermal explosions are the most likely of Yellowstone's various volcanic hazards, and the potential for additional future explosions is not insignificant.
Earthquakes in and around Yellowstone: How often do they occur?
The U.S. Geological Survey produces seismic hazard maps for the United States and the 2018 nationwide long-term assessment shows that the Yellowstone region has some of the highest seismic hazard values in the Intermountain West.
The complicated plumbing of hot springs and steam vents in Yellowstone National Park
Exploration and sampling of Yellowstone's thermal areas indicates that Yellowstone's hot springs often have surprisingly complex plumbing systems. It is not uncommon to find hot spring pools, which have one type of chemistry, and steam vents, which have totally different chemistry, located in close proximity—or even occupying the same space! Learn what happens when these mix or overlap.
Yellowstone—the year 2019 in review
Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is...
How do we know so much about Yellowstone deformation? Let's ask DZ!
Today, we'll pay homage to one of the scientists that made these discoveries: Dr. Daniel Dzurisin, who retires at the end of this week after over 43 years of service.
Science cowboys: The adventures of Yellowstone's early geologists
This preservation mandate made scientific research in YNP initially challenging to sort out—what is the balance between research and preservation, and how can you have one without the other?
The diverse chemistry of Yellowstone's hydrothermal features
Investigations into the water chemistry of Yellowstone's geysers, hot springs, mud pots, and streams and rivers have been conducted by the U.S. Geological Survey dating back to 1888.
