[3] Jet Geyser is a very accessible and intimate geyser, being close to a park road and alongside a boardwalk.

During series, eruptions are relatively frequent and less than one minute in duration.

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.
