Yellowstone, where there's always something new - USGS Caldera Chronicles
Yellowstone, where there's always something new Geologically speaking, things are always changing at Yellowstone—especially in the hydrothermal areas. It’s simply the nature of the complex hydrothermal system that overlies one of the planet’s largest magma reservoirs. Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Jefferson Hungerford, Park Geologist, and Kiernan Folz-Donahue, Field Geologist, both with Yellowstone National Park. The summer of 2024 was a busy time, with July’s hydrothermal explosion at Biscuit Basin and the first hydrothermal explosion ever recorded by geophysical monitoring data in Norris Geyser Basin. In addition to these higher energy events, a new hydrothermal feature popped up right in front of our eyes—literally! Media Sources/Usage: Public Domain.

The explosive story of Excelsior geyser - USGS Caldera Chronicles
The Explosive Story of Excelsior Geyser By Michael Poland Yellowstone Volcano Observatory December 30, 2024 Long before the 2024 explosion of Black Diamond Pool brought renewed attention to hydrothermal hazards in Yellowstone National Park, there was Excelsior Geyser. In the late 1800s, that feature set a standard for hydrothermal explosions. 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 On the morning of July 23, 2024, a hydrothermal explosion from Black Diamond Pool in Biscuit Basin sent people running for cover.
