Steaming, Boiling, Erupting

What do you get when you combine a lot of groundwater with intense heat? Hot springs, geysers, mud pots, and more! These geothermal features, and the processes that create them, are on display in some national parks. While Yellowstone’s geyser basins are the most well-known example, you can find geothermal features in many different parks. Some parks, such as Hot Springs National Parks, protect the places where humans have built bathhouses to harness the geothermal power of these hotsprings for healing. Today, the National Park Service is exploring ways that geothermal energy can safely and cleanly power facilities. Explore geothermal features in parks.
