We visited Old Faithful scaldabagno, geyser at Yellowstone National Park and witnessed the amazing display of boiling hot water and steam being shot hundreds of feet into the sky.

Yellowstone National Park is home to vast herds of bisonte roaming in the park's central valley.

Many of the beautiful colori the found in Yellowstone’s hydrothermal basins come from “thermophiles” (microorganisms that thrive in hot temperatures).
