Insider Guide to Yellowstone
Yellowstone National Park encompasses the largest hydrothermal area on the planet. Features include geysers, hot springs, mudpots and fumaroles.
Yellowstone was the site of a catastrophic volcanic eruption more than 600,000 years ago. During the eruption, the magma chamber was partially emptied which caused the roof to collapse, forming a giant caldera that covers the bigger portion of Yellowstone National Park.
Today, the magma chamber's partially-molten rock provides heat for Yellowstone's hydrothermal features which are in constant flux. Geysers and colorful terraces in Yellowstone are constantly changing, shaped by thermal activity.
