  The day that Porkchop Geyser exploded Release Date: June 28, 2021 Small hydrothermal explosions—steam blasts—are common at Yellowstone, occurring every year or two.  Most happen in the backcountry and are not observed by people.  In 1989, however, Porkchop Geyser blew up right in front of several observers on an otherwise sunny September afternoon. 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. Porkchop Geyser erupting in August 1989.

Yellowstone's biggest geyser goes off in a big way

  Travertine: Yellowstone’s Hydrothermal Timekeeper Release Date: May 24, 2021 Standing on the boardwalk next to any of Yellowstone’s hot, steamy, vigorously bubbling hot springs, mud pots, fumaroles, or geysers, you may be struck by the sheer amount of energy that powers this system, night and day. But how long have these features been active?  To address this question, geologists can turn to the “clock” that is frozen within hydrothermal travertine deposits. Yellowstone  Caldera  Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Lauren Harrison, a postdoctoral researcher with the U.S. Geological Survey. Travertine is a form of limestone composed of the minerals calcite and aragonite, which are both made of calcium carbonate (CaCO 3 ). In contrast to limestones that are formed in the ocean from the shells of tiny plankton and other ma
