Abstract
- This article discusses the geology of Yellowstone National Park in Idaho, Wyoming, and Montana, which is located in a basin formed as the crater, or caldera, of a supervolcano. The geysers of Yellowstone such as Sawmill and Old Faithful are powered by hydrothermal activity that is a remnant of volcanic activity in the region. Research by geologists including Francis Boyd and Bob Christiansen into the possibility that this supervolcano is still active is considered.
