Yellowstone Caldera Chronicles
Posted by Brent Schellhase on Aug 8th 2026
As we are located at the southern gateway to Yellowstone National Park and are "independent scholars" of 19th century Yellowstone history, we have a passion for both human history and geologic history of the Park. The US Geologic Survey (USGS) publishes a weekly email, Yellowstone Caldera Chronicles, writtten by scientists and collaborators of the Yellowstone Volcano Observatory. If you are interested in Yellowstone geology and history, you will enjoy the articles. We learn something new almost every week.
