Mammoth is a unique hydrothermal basin in Yellowstone National Park. You won’t observe geysers in Mammoth nor travertine at Old Faithful...why not? This seminar will answer those questions, and many more. The terraces at Mammoth need 320-Million-year-old limestones and fault systems that are active today in order to form.

Observations from the Norris Geyser Basin, the Northern range, and outside the northern boundary of the park will help to develop a full understanding of the complex and dynamic history and behavior of Mammoth Hot Springs.
