Where on Earth - March 2018

Clues for March 2018:

1. The presence of this hot spring, long considered sacred by Native Americans, was reported to Congress in 1871 by geologist Ferdinand Vandeveer Hayden as part of his survey of the geothermally endowed region that, the following year, would become the nation’s first national park.

2. The spring owes its brilliant bands of color to different species of thermophilic bacteria and archaea that live in successively cooler zones of water that encircle the center, where water heated to 87 degrees Celsius rises to the surface from 36 meters below.

3. At 112 meters across, it the largest hot spring in the United States, and the third largest in the world.
