This vertical aerial photo (with south to the top) shows the Gráakúla scoria cone at the lower left, which erupted about 4,000 years ago and produced this lava flow that entered Selvallavatn lake. The flow is part of the Ljósufjöll volcanic system, which contains of a group of scoria cones and lava flows along a roughly 90-km-long WNW-ESE trend.
