One of the most famous geysers in the world is Old Faithful in Yellowstone National Park. It erupts every 90 minutes, varying only be a few minutes each time. It is a very popular sight to see, with crowds building well in advance of the eruption. You can see a line of people on the far side of the geyser in this picture.
Eruptions vary in height from 106 feet (32 meters) to 184 feet (56 meters). These three pictures were taken from the same eruption over a span of about a minute, so you can see it pulses during the eruption.
All photos taken by myself.
