Location: Upper Geyser Basin, Yellowstone National Park, Wyoming, USA | Anemone Geyser erupts, Old Faithful Inn visible in the distance. Anemone Geyser cycles about every 7 minutes. First the pools fills, then overflows, then bubbles and splashes before erupting. The eruption empties the pools and the cycle begins anew. Upper Geyser Basin.

Location: Yellowstone National Park, Wyoming, USA | Castle Geyser erupts with the colorful bacteria mats of Tortoise Shell Spring in the foreground. Castle Geyser reaches 60 to 90 feet in height and lasts 20 minutes. While Castle Geyser has a 12 foot sinter cone that took 5,000 to 15,000 years to form, it is in fact situated atop geyserite terraces that themselves may have taken 200,000 years to form, making it likely the oldest active geyser in the park. Upper Geyser Basin.
