Yellowstone National Park

Mammoth Hot SpringsMammoth Hot Springs is a series of natural terraces formed by thermal water and mineral deposits. The white rock is made up of travertine deposits, while the other colors are the result of living microorganisms and bacteria that live in the thermal features.
Old FaithfulOld Faithful is one of more than 300 geysers in Yellowstone. Contrary to popular belief, the time between Old Faithful's eruptions actually varies quite significantly over the years. Currently, the average interval between eruptions is about 94 minutes.
The Geyser BasinsYellowstone contains the greatest concentration of geysers in the world. The Upper Geyser Basin alone contains one-fourth of the total number of geysers in the world. A number of other hydrothermal features can be found in Yellowstone as well. Besides hot springs and geysers, there are also mud pots and mud volcanoes (formed when hot water mixes with clay) and fumaroles, which emit hot water vapor and gasses.
