The Fjaðrá gorge

 

Our route takes us over some of the older geological formations in Iceland.  Here we have stopped at a deeply dissected river valley in early Pleistocene móberg rocks. Móberg is the Icelandic term for subglacially erupted hyaloclastic deposits, which have become altered and consolidated. The rocks have a distinctive brownish colour. Steep- sided gorges like this beauty spot reflect the erosive power of many subglacial jökulhlaup floods in the past.
