Dettifos is like no other waterfall I had ever seen. It was not gentle, it was not white flowing water. It has a drop of 44m and is 100m wide and it seems that each drop of water fights not to go over the edge.
It churns, splashes and surges until it reaches the point of no return, and even as the milky coloured glacial water falls over the edge it seems to fight gravity all the way down, and suddenly rises up again in the form of massive plumes of spray
