The snow-mantled Reykjanes volcanic system forms the SW tip of the Reykjanes Peninsula, where the Mid-Atlantic Ridge rises above sea level. The Reykjanes volcanic system is the westernmost of a series of four closely spaced, NE-SW-trending en echelon fissure systems that extend diagonally across the Reykjanes Peninsula. Most of the Reykjanes volcanic system is covered by Holocene lavas, and eruptions have occurred in historical time during the 13th century at several locations.
