Beehive Geyser, Yellowstone National Park Poster

"Beehive Geyser, Geyser Hill, Upper Geyser Basin, Yellowstone National Park, Wyoming" by Catherine Sherman. Steam rises from Beehive Geyser, a cone geyser, in the stark landscape of Geyser Hill, Upper Geyser Basin in Yellowstone National Park, Wyoming, surrounded by sparse vegetation and distant pine trees. Walkways and trails wind through the unstable landscape, enabling closer observation of the many geothermal features on Geyser Hill. Beehive Geyser's four-foot (1.2 metre) tall cone resembles a straw beehive. Beehive's Indicator is a small, jagged cone-type geyser located about 10 feet (3.0 m) from Beehive. Beehive's Indicator, sends up a 6-to-15-foot (1.8 to 4.6 metre) fountain between a few seconds and 30 minutes before Beehive erupts, averaging 15 to 20 minutes prior. Eruptions of Beehive Geyser last about five minutes and are 200 feet (61 metres) high. The fountain maintains its full height for the duration of the eruption, dropping just slightly near the end. A short, weak steam phase concludes the eruption. The interval between eruptions ranges from less than 10 hours to over a day. The Upper Geyser Basin is the largest geothermal basin in the park. Additionally, the Upper Geyser Basin is recognised as the basin with the highest concentration of geysers in the world.
