Gígjökull (Gigjokull) Glacier
Gigjokull is one of two glacier outlets from the glacier volcano Eyjafjallajokull, the other being Steinholtsjokull.
The 2010 Eyjafjallajokull eruption was close to the head of Gigjokull. Gigjokull empties out of the summit crater area at 1600 meters, flows across the ice cap to 1500 meters and then descends in an icefall down 200 meters. Water flowing rom Gigjokull enters the Markarfljot river and eruptions in the area have caused great glacier bursts, 2010 being indeed the latest example.
