Steam rises from a hot pool in the Olkeduháls geothermal area of the Hrómundartindur volcanic system, which lies south of Thingvallavatn lake. The geothermal field contains numerous hot springs, mud pools and fumaroles. Steam plumes are visible at three locations in the background. The Hengill volcanic system forms the ridge on the skyline immediately west of the Hrómundartindur system.
