Beehive Geyser

Beehive Geyser is a geyser in the Upper Geyser Basin of Yellowstone National Park in the United States.

Eruptions

Eruptions of Beehive Geyser last about 5 minutes and are 200 feet (60 m) high. The fountain maintains its full height for the duration of the eruption. Dropping just slightly near the end. A roaring steam phase concludes the eruption and can be heard a quarter-mile away. The interval between eruptions range from 8 hours to one day during the summer. Winter eruptions are very erratic. There are occasions in both summer and winter that there are a series of eruptions that are quite regular. These eruptions have an interval of 10-20 hours with longer intervals near the end of the series.

equence

Near Beehive is a smaller geyser that can often be used as an indicator of a pending eruption of Beehive. This geyser, named Beehive's Indicator, sends up a 15—25 foot (4.5—7.6 m) fountain between a few seconds and 30 minutes before Beehive erupts, averaging 15—20 minutes prior. Once Beehive starts erupting, the Indicator continues to play for part of the Beehive eruption and then stops playing.

For a period of three years in the 1990s, Beehive was dormant. During this time, the Indicator would erupt for extended periods, as long as 60 minutes, with no Beehive eruption.

Physical structure

Beehive Geyser was named in 1870 by the Washburn Expedition. They thought the 4–foot (1.2–m) tall cone resembled a beehive. Beehive's Indicator is a small, jagged cone-type geyser located about 10 feet (3 m) from Beehive.
