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.
