  7. A geiser: Old Faithful in Yellowstone National Park erupts every day with predictibility -

    Eruptions can shoot 3,700 to 8,400 U.S. 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]

    [edit] Increasing interval

    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]
