Öræfajökull, seen here from Höfn across Hornafjörður, is the most SE point of Iceland and has always been a landmark for sailors. The name means "wasteland glacier" and denotes both the glacier and the stratovolcano lying underneath it.
Looks are deceptive, Öræfajökull is thought to be Europe's 2nd largest stratovolcano after Etna with a massive 600-700m deep ice filled caldera and an altitude of 2110m, making it Iceland's highest mountain.

The white flowers in the foreground are Angelica sylvestris (see note),
