, 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 usually erupts in long-duration series. During series, eruptions are relatively frequent and less than one minute in duration. Jet Geyser's behavior is influenced by nearby (and much bigger)

. Jet eruptions usually occur every 7 to 30 minutes, with the frequency increasing as a Fountain Geyser eruption nears. Jet erupts every 1 to 4 minutes during most Fountain Geyser eruptions. After Fountain has quit, Jet usually quits. Approximately mid-way through a Fountain Geyser interval, Jet often starts a new eruption series. Jet is a cone-type geyser with at least five vents that erupt in different directions (vertical, angled, and subhorizontal). The vents produce varying quantities of water and steam for about 0.25 to 1 minute. The central vent will usually erupt to about .
