Beehive Geyser is the tallest regularly-performing geyser in the Geyser Hill Group of Yellowstone's Upper Geyser Basin. Eruption columns are steady, relatively slender, and reach 150 to 200 feet high. In recent years, Beehive Geyser erupts approximately once a day for about five minutes. Eruptions are usually preceded by an eruption from Beehive's Indicator Geyser, located about 7 feet away from the northeastern base of Beehive's cone.


Beehive Geyser's cone is about 4 feet tall and subcylindrical. The vent at the summit is relatively small. The cone itself is composed of geyserite - also called siliceous sinter. Geyserite is a friable to solid chemical sedimentary rock composed of opal (hydrous silica, a.k.a. opaline silica: SiO2·nH2O). It forms by precipitation of hydrous silica from hot spring water. Geyserite is the dominant material at & around Yellowstone hot springs and geysers (the Mammoth Hot Springs area is a major exception to this). The silica in the geyserite is ultimately derived from leaching of subsurface, late Cenozoic-aged rhyolitic rocks by hot and superheated groundwater. Rhyolite is an abundant rock at Yellowstone.


The outer walls of the cyclindrical portion of Beehive's cone are slightly irregular and nondecorated. The summit is mostly covered with nodulose to pustulose geyserite. Historically, the outer walls of Beehive were also covered with nodulose geyserite - this was thoroughly vandalized by tourists. See:
