Grand and Castle Group

Gizmo Geyser erupts from a collection of vents at the base of Castle's cone. Intervals range from 5-20 minutes, durations range from 1-5 minutes and heights range from inches to about 15 feet. The most noticeable thing about Gizmo's eruption is its loud steam-phase. The steam-phase come periodically and involve at least three of Gizmo's vents. It is during the steam-phase that Gizmo is its tallest with one vent reaching about 15 feet. Even if you are not watching for them, Gizmo's steam phases are loud enough to get your attention.
