The name Dettifoss could be loosely translated as ‘The Collapsing Waterfall’. The Dettifoss waterfall is with the greatest volume of any waterfall in Europe, 500 cubic metres of water per second plunges over the edge. Dettifoss is 45 m high and 100m wide. The water comes from the nearby Vatnajökull glacier, whose sediment-rich runoff colors the water a greyish white.
