Old Faithful of California - Calistoga, CA - Hot Springs on Waymarking.com

There are only two other "old faithful" geysers in the world that have earned the title due to their regular eruptions. Water for the Old Faithful Geyser of California comes from an underground river. When this water flows over the hot molten magma deep in the earth, it boils and expands and is collected in large cavities. Under tremendous pressure from the heat, and assisted by a constriction of the passage upward, the superheated water is forced through the fissures and fractures and erupts with an outpouring of steam followed by a fulmination of hot dancing water.

Under normal conditions, the water, the heat and the underground structure all remain constant and for this reason Old Faithful erupts regularly. Conditions which cause deviations from the normal pattern seem to relate to earthquakes. The Old Faithful Geyser of California is proving itself a predictor of quakes.
