Track of Yellowstone hotspot

1905 (approx.)

Detailed Description

Shaded relief map showing the path of the Yellowstone hotspot. Yellow and orange ovals outline past caldera eruptions during the time periods indicated (orange calderas are the most recent). The calderas progress from oldest in northern Nevada to youngest in Yellowstone National Park as the North American plate passed over the relatively stationary hotspot. Black lines indicate faults. Figure is from the book "Windows into the Earth: The Geologic Story of Yellowstone and Grand Teton National Parks," by Robert Smith and Lee Siegel. Used with permission.
