Emerald Spring in Yellowstone National Park

The spring gets its name from 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.

 

Emerald Spring is 27 feet (8.2 m) deep. The water temperature in the spring is around 83.3 °C (181.9 °F).

 

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 (18.2â22.9 m) in height.
