Hofsjökull – “temple glacier” – is the largest active volcano and the third-largest glacier in Iceland. It is the source of major rivers on the island including its longest, Þjórsá.
In this shot taken from a helicopter, we see the outlet glacial tongue Múlajökull and glacial rivulets that coalesce in this neighbourhood to give rise to Þjórsá. The sight is a geologists’ delight; a trained eye will discern several classical features of this glacial field.
