Emerald Spring is a boiling hot spring located in Norris Geyser Basin of Yellowstone National Park.

Emerald Spring is 27 feet (8 m) deep.[1] The water temerpature in the spring is around 172°F (78°C).[2] The spring gets its name the emerald green color of the water created by sunlight filtering through the water, giving the light a blue color, and reflecting off the yellow sulphur creating the green hue.[3]

While Emerald Spring is a mostly calm pool, which usually only has a few bubbles rising to the surface, it does experience periods of turbidity and small 3-foot (1 m) high eruptions. In 1931, Emerald experienced a period of extremely vigorous activity with eruptions measuing 60 to 75 feet (18.2–22.9 m) in height.[4]
