Spasmodic Geyser

The wild waters washing up out of this hole in the earth are a reminder of the massive movement and mystery occurring beneath the crust's surface. The aquatic acoustics of this geologic feature are freshly flowing everyday in an endless expression of the planet's persistent and pertinent power over the overconfident crowds that gather around to watch its natural wonder. The word geyser comes from Geysir, the name of an erupting spring at Haukadalur, Iceland; that name, in turn, comes from the Icelandic verb geysa, "to gush", the verb itself from Old Norse. The formation of geysers is due to particular hydrogeological conditions, which exist in only a few places on Earth, so they are a fairly rare phenomenon. Generally all geyser field sites are located near active volcanic areas, and the geyser effect is due to the proximity of magma. Generally, surface water works its way down to an average depth of around 2,000 metres (6,600 ft) where it contacts hot rocks. The resultant boiling of the pressurized water results in the geyser effect of hot water and steam spraying out of the geyser's surface vent.
