Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week s contribution is from Mike Poland, geophysicist with the U.S. Geological Survey and scientist-in-charge of the Yellowstone Volcano Observatory.
How many earthquakes were located in the Yellowstone region in 2020? What geysers have been active recently? What sort of volcanological research is being done in Yellowstone right now? It can sometimes be hard to find such information compiled in a single, easy-to-navigate source.
But not anymore.
Weâre pleased to announce publication of the 2020 Yellowstone Volcano Observatory annual report, which can be accessed at https://pubs.er.usgs.gov/publication/cir1482.

Visitors to Yellowstone might have noticed a small sign between Mammoth Hot Springs and Norris Junction that points down a side road to âSheepeater Cliff.â A short drive down this road reveals an exceptional example of a common feature of volcanic flows: columnar jointing.
Sheepeater Cliffs is part of a basaltic lava flow that erupted north and outside of Yellowstone Caldera about 500,000 years ago. These sorts of lava flows, which are similar to those erupted in Hawaii, are common around the edge of the caldera, but they canât erupt in the caldera because the denser lavas from the basaltic magma chamber are blocked from rising to the surface by the overlying chamber of viscous rhy

Every historic building in Yellowstone has a story to tell. You may be familiar with the impressive Old Faithful Inn or Fort Yellowstoneâs tidy rows of red-roofed buildings. But not every historic building is so recognizable. In fact, the oldest one still standing in the park is viewed by relatively few people. It is a humble little structure, off the beaten path, with a unique story of its own.

We do not define the habitat of wolves just by observing where a wolf pack may be standing at any given moment; they move around. Similarly, you can think of a thermal area as the âhabitatâ of individual thermal features, like geysers and hot springs. Hot fluids also move around (underground), so just because a patch of ground in Yellowstone is either warm or cool doesnât mean it will stay that way.
