Lava field west of Krýsuvík, actually formed by two lava flows in the mid-12th century. The main lava flow entered the sea between Selatangi point and the Krýsuvikurberg cliff. Two “islands” stand up from Ögmundarhraun and ruins of a farmhouse and the walls around its fields can be seen on one of them (Húshólmi), disappearing beneath the lava.
