Beehive Geyser, Upper Geyser Basin, Yellowstone Park, 1911-1913

Yellowstone National Park, established 1872, was America's first national park. Approximately two square miles in area, Upper Geyser Basin contains the largest concentrations of geysers in the park--in fact, nearly one-quarter of all the geysers in the world. This geyser is aptly named, as its four-foot-tall cone resembles a beehive.
