At their northern terminus the 1984 lava flows form a dark lava field north of Krafla caldera. The northernmost eruptive vents can be seen steaming at the upper left on September 10, about halfway through the two-week-long eruption. The flat-topped peak at the upper right is Gæsafjöll, one of Iceland's many table mountains, which formed as a result of repeated eruptions through a glacial icecap.
