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.

Echinus Geyser erupts at sunset. Echinus Geyser reaches heights of 40 to 60 feet. Echinus Geyser was quite predictable until 1998 when something changed in its plumbing, and it now is irregular and erupts less often.
