Mammoth in Yellowstone National Park in Park County, Wyoming — The American West (Mountains)
Fumaroles
High Heat and Low Water
The hottest of Yellowstone’s geothermal features are fumaroles (steam vents). Fumaroles in Norris Geyser Basin have measured up to 280°F (138°C). A plentiful water supply would help cool these features; however, steam vents are usually found on hillsides or higher ground, above the basin’s water supply. They rapidly boil away what little water they contain; releasing steam and other gases forcefully from underground.
