Yellowstone is full of water features. Listen to a small fumarole in this audio postcard.
Immerse yourself in Yellowstone's aural landscape.
Fumaroles, Hot Springs, Geysers! You can find them all in Yellowstone.
Thermal features are habitats for microscopic organisms called thermophiles: "thermo" for heat, "phile" for lover.
