Road Trip: Day 4
Grand Geyser is one of tallest geysers in the world, and the tallest predictable one. It is amazing, reaching heights of 200′ and often erupting simultaneously with Vent Geyser and Turban Geyser, both of which are very near to Grand Geyser and are connected to it hydrodynamically. Grand Geyser lies in the Upper Geyser Basin of Yellowstone National Park. Grand Geyser is a fountain-type geyser, meaning it erupts with a broad fountain of spray rather than the focused hose-like spray of a cone-type geyser such as Riverside Geyser, Old Faithful Geyser or Castle Geyser. Grand Geyser’s 12-hour interval is long but predictions are fairly accurate, and its show is worth the wait, especially late in the day at which time rainbows can form in the spray. Grand Geyser has an initial burst lasting about 10 minutes, followed by a cessation of activity at which point many viewers leave. But it can suddenly resume its eruption with a second burst which is often higher and more powerful than the first, so stick around when you think the show is over since it may start up again better than before.

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.
