Emerald Spring, Hot spring in United States of America
Emerald Spring is a stunning hot spring located in Yellowstone National Park.
Yellowstone, established in 1872, is the first National Park in the U.S. and is home to Emerald Spring.
The spring is named for its emerald green color, influenced by the depth of the water.
Visitors can view Emerald Spring from designated boardwalks around the Norris Geyser Basin area.
The high temperature of the water sustains an exotic ecosystem including thermophilic bacteria.
