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.

Grand Geyser (right), Turban Geyser (center) and Vent Geyser (left) erupt in concert. An apron of bacteria covered sinter occupies the foreground when water from the eruptions flows away. Grand Geyser is a fountain-type geyser reaching 200 feet in height and lasting up to 12 minutes. Grand Geyser is considered the tallest predictable geyser in the world, erupting about every 12 hours. It is often accompanied by burst or eruptions from Vent Geyser and Turban Geyser just to its left. Upper Geyser Basin.
