Yellowstone National Park is renowned for its geothermal features, especially its geysers. It is considered the most active geyser basin in the United States, attracting millions of visitors annually. The park’s unique geological activity is due to its location atop a supervolcano.
Geyser Basics
Geysers are hot springs that periodically erupt with water and steam. They are formed when underground water is heated by volcanic activity. The pressure builds until it forces the water to the surface in a spectacular eruption.
Yellowstone’s Geyser Features
Yellowstone hosts over 500 geysers, including the famous Old Faithful. The park’s geysers are part of a larger geothermal system that includes hot springs, mud pots, and fumaroles. These features are indicators of the park’s ongoing volcanic activity.
Notable Geysers
- Old Faithful: Known for its regular eruptions approximately every 90 minutes.
- Steamboat Geyser: The tallest active geyser in the world, capable of eruptions over 300 feet.
- Castle Geyser: Features a large cone and frequent eruptions.
