Beehive Geyser is a geyser in the Upper Geyser Basin of Yellowstone National Park in the United States. The 4-foot (1.2 m) tall cone resembles a beehive. Beehive's Indicator is a small, jagged cone-type geyser located about 10 feet (3.0 m) from Beehive.
Eruptions of Beehive Geyser last about 5 minutes and are 200 feet (61 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 to 20 hours with longer intervals near the end of the series. As of summer 2009 Beehive was having predictable eruptions every 11 to 14 hrs.
