Old Faithful is a cone geyser located in Yellowstone National Park. It was named in 1870 for its frequent and somewhat predictable eruptions, which number more than a million since Yellowstone became the world's first national park in 1872. Eruptions can shoot 3,700 to 8,400 gallons of boiling water to a height of 106 to 185 feet, lasting from 1.5 to 5 minutes.
Mammoth Hot Springs is a large complex of hot springs on a hill of travertine in Yellowstone National Park. It was created over thousands of years as hot water from the spring cooled and deposited calcium carbonate. The terraces are constantly evolving and changing, with new features appearing and others disappearing. Visitors can take a boardwalk tour of the area, which offers stunning views of the unique formations and vibrant colors.
Grand Prismatic Spring is the largest hot spring in the United States, and the third largest in the world. Its rainbow-like colors are caused by pigmented bacteria and microbial mats that grow around the edges of the mineral-rich water. Visitors can view the spring from a boardwalk trail that offers stunning views of the colorful water and surrounding landscape.
Yellowstone National Park was established in 1872 by an act of Congress, making it the world's first national park.
