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.
