Rampart of the Giantess.
The Grjótgarðsháls ridge in the northern Highlands of Iceland holds one of the most startling sights anywhere: a wall of large boulders over 300 m in length and 5 m high set in a sweeping moraine dotted with glacial erratics.
The geological explanation for this wondrous landscape lays it at the door of the Brúarjökull glacier during the last Ice Age. The scientific explanation involves a fight between two female trolls for territorial supremacy.
The extent of Skessugarður – from Skessa (Giantess) and garður (in this context a fortress or rampart) – is best appreciated from the air. Watch the video short below.
