The temperature scale is in degrees Fahrenheit. This is a night-time eruption of Fountain Geyser in the Fountain Group of Yellowstone's Lower Geyser Basin. Fountain Geyser is a large, regularly-erupting feature. It has a moderately large, irregularly polygonal surface vent that is 6 to 12 meters across. The vent is surrounded by a geyserite platform with moderately developed concentric ridges at its eastern edge. Eruption starts are preceded by a relatively rapid rise in water level. Eruptions occur every ~4.5 to 6 hours and last for about 30 minutes. Some eruptive bursts reach up to ~80 feet high. Much of the erupted water volume moves northward into Morning Geyser's basin, which overflows and then heads north into a large field of weathered geyserite gravel. Bursting patterns show that Fountain Geyser erupts from two major subaqueous vents. In 1998, researchers measured Fountain Geyser's water temperature at 83.4° Celsius (= 182° Fahrenheit), with a pH of about 8.5. |
