Spasmodic Geyser

Spasmodic Geyser is a small geyser in the Upper Geyser Basin. It contains vents of both the fountain and cone types. Spasmodic Geyser is in the Sawmill complex and is closely connected to Sawmill, Penta, and other geysers in this area.

Eruption Pattern
Spasmodic Geyser's eruptions from the two craters can be up to 15 feet (4.6 m) high. Water can also erupt from a few inches to ten feet high from the approximately 20 vents. The intervals between eruptions are irregular, but most are in the 1-3 hour range.

History
Spasmodic Geyser was named by A.C. Peale, from the 1878 Hayden survey team, for its erratic eruptions.
