Reykjanes is covered by sixteen lava fields created by eruptions from the 8th through the mid-13th centuries. The peninsula is also scarred by a row of craters named Eldvöp. Beneath the ravaged surface is thermal activity where temperatures can exceed 500° Fahrenheit. When the gasses and steam escape through a fumarole, the billowing white clouds are a dramatic show. This steam vent is Gunnuhver.
