Detailed Description

A portion of organic-rich lake mud recovered from Rush Lake, in the Lower Geyser Basin of Yellowstone National Park. Younger sediments are to the left and older sediments are to the right. The researcher is pointing to a thin, white layer—the Mazama ash, produced during the eruption 7600 years ago that formed Crater Lake in Oregon. Photo taken by Chiara Smythies, August 14, 2023.
