Description

Kleifarvatn

The mud pools take form where steam from boiling geothermal reservoir water emanates and condenses and mixes with surface water. Accompanying gases such as carbon dioxide and hydrogen sulphide make the water acid. This causes alteration of the fresh lava rock to clay.

Steaming of the ground at Reykjanes increased markedly as a consequence of a pressure drawdown in the geothermal reservoir upon the start of production from the reservoir in 2006.

Iceland's largest mud pool at present prominent, highest up in the Gunnuhver group. It is 20 meters wide across a rim of mud, boiling vigorously.

Two ramps are located at the Gunnuhver group, on close to Gunnuhver itself where you can look down to the spring and hear the vigorous noise, see the boiling water and feel the power bursting from the ground and the steam on your face. The other ramp is located on Kísilhól a silica hill. From there you have a good view over Gunnuhver group and surroundings.
