The mud pools and steam vents
on the southwest part of Reykjanes close to Reykjanes
lighthouse are collectively named Gunnuhver after a female
ghost that was laid there. She had caused great disturbance
until a priest set a trap for her and she fell into the
spring. This happend about 400 years ago.
mud pools form where steam from boiling geothermal resevoir
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 geothremal
reservoir upon the start of production from the reservoir in
Iceland´s larges mud pool at present prominent, highest up
in the Gunnuhver group. It is 20 meters wide across a rim
of mud, boiling vigorously.
ramps are located at the Gunnuhver group, on close to
Gunnuhver itself where you can look down to the spring and
hear the vigorous noice, see the boiling water and feel lthe
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
Gunnuhver is the heart in a future geopark where the North
Atlantic ridge is rising from the ocean, you find 100
different craters and lava, bird cliffs, high geothermal
area, sand beach,The Bridge Between Continents, powerplant,
lighthouses and exhibitions amongst other things.
