Old Faithful is a cone geyser located in Yellowstone National Park in the United States. Old Faithful was named in 1870 during the Washburn-Langford-Doane Expedition and was the first geyser in the park to receive a name.[1][2] Old Faithful can refer to: Old Faithful Geyser in Yellowstone National Park Old Faithful Quasar Old Faithful, rugby league song Old Faithful (Hope & Faith episode) the name of Graeme Obrees bicycle Category: ...

Strokkur geyser, Iceland A geyser is a type of hot spring that erupts periodically, ejecting a column of hot water and steam into the air. ... Yellowstone redirects here. ... The Washburn Expedition of 1870, explored the region of northwestern Wyoming that a couple years later became Yellowstone National Park. ...


An eruption can shoot 3,700 to 8,400 gallons (14–32 kL) of boiling water to a height of 106–184 feet (30–55 m) lasting from 1.5 to 5 minutes. The average height of an eruption is 145 feet (44 m).[3] Eruptions often occur about 90 minutes apart, but this interval can range from 45 to 125 minutes on occasion.[4] More than 137,000 eruptions have been recorded. Harry M. Woodward first described a mathematical relationship between the duration and intervals of the eruptions (1938).[citation needed] Old Faithful is not the tallest or largest geyser in the park; that title belongs to the less predictable Steamboat Geyser.[2] Harry M. Woodward was a US geologist who, in 1938, first described a mathematical relation between the durations and intervals of eruptions from the Old Faithful Geyser. ... In science, a mathematical relationship describes how one quantity is related to another. ... A duration is an amount of time or a particular time interval. ... With regards to time, an interval is the duration between two events or occurrences of similar events. ... Major eruption, Steamboat Geyser, circa 1960s. ...


Over the years, the length of the interval has increased, which may be the result of earthquakes affecting subterranean water levels. These disruptions have made the earlier mathematical relationship inaccurate, but have in fact made Old Faithful more predictable. With an error of 10 minutes, Old Faithful will erupt 65 minutes after an eruption lasting less than 2.5 minutes or 92 minutes after an eruption lasting more than 2.5 minutes. The reliability of Old Faithful can be attributed to the fact that it is not connected to any other thermal features of the Upper Geyser Basin.[5] This article is about the natural seismic phenomenon. ... The geothermal areas of Yellowstone include several geyser basins in Yellowstone National Park as well as other geothermal features such as hot springs (including mud pots) and fumaroles. ...


Between 1983 and 1994, four probes containing temperature and pressure measurement devices and video equipment were lowered into Old Faithful. The probes were lowered as deep as 72 feet (22 m). Temperature measurements of the water at this depth was 244°F (118°C), the same as was measured in 1942. The video probes were lowered to a maximum depth of 42 feet (13 m) to observe the conduit formation and the processes that took place in the conduit. Some of the processes observed include fog formation from the interaction of cool air from above mixing with heated air from below, the recharge processes of water entering into the conduit and expanding from below, and entry of superheated steam measuring as high as 265°F (129°C) into the conduit.[6]
