The Ljósufjöll volcanic system at the eastern end of the Snæfellsnes Peninsula is composed of a group of cinder cones and lava flows erupted along short fissures on a roughly 90-km-long WNW-ESE line. The crest of the Ljósufjöll range is seen here from the south with glacial moraines descending its flanks. The latest eruption at Ljósufjöll post-dated the settlement of Iceland, and took place about 1000 years ago.
