Fumaroles, or steam vents, are the hottest hydrother- mal features in the park. They are easier to see in cool weather.

Geysers erupt with steaming hot water. Variations in each geyser's underground reservoir determine whether it is regular and predictable—like in the Upper Geyser Basin—or irregular like in Norris Geyser Basin.

Hot springs are the most common hydrothermal features in the park. They vary from frothing mocha- like boiling water to clear and calm pools of tremen- dous depth.

Mudpots are acidic features with a limited water supply. Their consistency and activity vary with the seasons and precipitation.

Travertine terraces are found at Mammoth Hot Springs, where the interactions of water and lime- stone create chalk-white travertine.
