Map of the Yellowstone Hot-Spot Track.

Map of the Yellowstone hot-spot track.

The park is about 240 km (150 mi) southwest of Yellowstone National Park. The map highlights the Yellowstone hot-spot track, which is composed of seven volcanic fields. The hot spot remained stationary as the North American plate moved to the southwest (arrow). The ages (in millions of years, on the figure) of the various volcanic fields indicate this progression, starting with the McDermitt volcanic field (approximately 16.5 million–15 million years ago) to the present location under Yellowstone. The park area was situated over the hot spot between about 6.5 million and 4.3 million years ago. Heise Group (Th) rhyolitic rocks in the northern part of the park represent that period of time. Ages are from Smith and Siegel (2000).
