Iceland's largest geysers are located in the Haukadalur basin, part of the Geysir volcanic system, just east of the southern end of the Oddnyjarhnjukur-Langjokull fissure system. Here, the Strokkur geyser can be seen just as a burst of boiling water and steam erupts from a pool. This geyser erupts about every 10 minutes, producing a short-lived fountain that usually reaches about 20 m.
