Yellowstone National Park is renowned for its abundant hydrothermal features, which represent about half of the world's known geothermal activity. These features are a direct result of the area's volcanic nature, with groundwater interacting with magma or hot igneous rocks close to the surface.12

The park boasts over 10,000 hydrothermal features, including:
* Geysers: More than 300 geysers are found here, over half of the world's total. Famous examples include Old Faithful, Steamboat Geyser (the world's highest-erupting geyser), and Giantess Geyser.1
* Hot Springs: These are characterized by colorful, mineral-rich waters. Notable examples include Morning Glory Pool and the terraces of Mammoth Hot Springs.1
* Fumaroles: Steam vents that release volcanic gases.1
* Mud Cauldrons and Paint Pots: Areas where hot water and volcanic gases interact with clay-rich soil to create bubbling mud.1

These features are primarily located in basins such as the Upper, Midway, and Lower Geyser basins, as well as Norris Geyser Basin. The underlying magma dome and a network of faults contribute to the ongoing seismic and geothermal activity in the region.13
