Original Geyser

The Great Geysir gives its name to all other geysers worldwide

Geysir, located in Iceland's Haukadalur valley, is the original geyser from which all others take their name. This ancient hot spring has been erupting for over 1,000 years, though its activity has varied dramatically over time. The Great Geysir sits atop a vast geothermal system powered by the Mid-Atlantic Ridge, where the North American and Eurasian tectonic plates are slowly pulling apart, creating the geological instability that makes Iceland a land of fire and ice.
