Geysir in the Haukadalur valley, Iceland, is the oldest known geyser. The
English word geyser to describe a spouting hot spring derives from Geysir.
Eruptions at Geysir can hurl boiling water up to 60 metres in the air.
However, eruptions may be infrequent, and have in the past stopped
altogether for years at a time.
