Gunnuhver geothermal area is a field of steaming fumaroles and boiling mud pools. In the recent past some geysers existed here as well. As the tectonic plates move, new passages are constantly opening (and older ones are closing) for heated groundwater and gases. Gunnuhver is one such area. Here deeper below the surface the temperature of ground (and water in it) reaches 300° C. Much of groundwater comes from the nearby sea and is rich with chlorides and also with dissolved silica. As a result in the recent past hot springs and geysers have created sinter deposits - a hill named Kísilhóll (Kísilhóll, Silica hill). Today here are no hot water springs and geysers, but northeast from Kísilhóll are located many steam vents (fumaroles) and boiling mud pools. Mud pools are formed by acidic groundwater sources, which turn lava into clay. The largest mud pool in Iceland also is located here - it is 20 m across, boiling vigorously along its rims. Hot ground is an immense source of energy. In 2006 near Gunnuhver geothermal field started to operate the Reykjanes Geothermal Plant. As a result the steaming of the ground in the geothermal field increased.
