There are nine named plateaus in Yellowstone National Park. These plateaus are part of the much larger Yellowstone Plateau and dominate areas in the park south and west of the Gallatin and Absaroka mountain ranges. Four of the plateaus are from rhyolite lava flows that occurred between 110,000 and 70,000 years ago.
