Eriophorum callitrix, commonly known as Arctic Cotton, Arctic Cotton Grass, Bog Cotton or Suputi in Inuktitut, is an Arctic plant in the Cyperaceae family (sedge family). It is able to flourish in areas that are too cold for trees. This is a perennial plant with narrow leaves and flowering heads with dense bristles that persist as long white hairs in the fruiting stage. Cotton grasses are found growing with mosses and lichens in cold bogs and swampy ground.
The falls flows at about 500 cubic meters per second at high flow, with dimensions of 44m tall and 100m wide. Add it all up and we witnessed a monster that is quite possibly Europe's largest and most powerful waterfall (let alone Iceland's biggest). The milky color of the waterfall is due to the fact that the massive river is fed by the sediment-rich meltwaters of the vast Vatnajökull glacier.
These silica rich depositions are created as hot borehole water is released from the power plants into cooling ponds. As the water cools, dissolved silica comes out of solution forming intricate patterns in and around the volcanic rock.
