The Brennisteinsfjöll volcanic system, located east of Kleifarvatn lake, consists of a series of NE-SW-trending crater rows and small shield volcanoes. Brennisteinsfjöll is seen here in an aerial view from the south with youthful light-colored lava flows spilling over an E-W-trending coastal scarp. An eruption in 1000 CE was dated by its occurrence at the time of a meeting of the Icelandic outdoor parliament at Thingvellier. The most recent eruption at Brennisteinsfjöll took place in the 14th century.
