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.

Great Fountain Geyser erupting. Great Fountain Geyser, a fountain-type geyser, can reach heights of 200 feet, one of the largest geysers in the world. It has a large vent (16 feet across) situated amid wide sinter terraces that act as reflecting pools as the geyser slows fills prior to its eruption. Its interval and duration vary widely. It typically erupts in a series of bursts, each separately by a few minutes. Firehole Lake Drive.

Castle Geyser erupts, reaching 60 to 90 feet in height and lasting 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.
