On Wikipedia

Jet Geyser is a geyser in the Lower Geyser Basin of Yellowstone National Park in the United States. Jet Geyser is in the Fountain Group that includes Fountain Geyser, Morning Geyser, Red Spouter and Silex Spring. Jet Geyser is a very accessible and intimate geyser, being close to a park road and alongside a boardwalk. Jet's eruptions are generally frequent but unpredictable. Its behavior is closely linked to nearby (and much bigger) Fountain Geyser. Eruptions can be expected every 7 to 30 minutes with the frequency increasing as the time for an eruption of Fountain Geyser approaches. Jet is a cone-type geyser and erupts from at least five vents. The vents produce varying quantities of water and steam for about a minute. The central vent will usually erupt to about 20 feet (6.1 m).
