Fumaroles, often known as steam vents, are a familiar attraction at Yellowstone National Park. Steam vents are technically hot springs, but the small amount of water boils away before it reaches the surface causing extreme amounts of steam. Steam vents are known for their hissing sound, similar to that of a tea kettle.
