Gullfoss - Frosen waterfall
Gullfoss is in the river Hvítá (engl. white river), which has its origin in the glacier lake Hvítávatn (engl. white river lake) at Lángjökull glacier about 40km north of Gullfoss.
Glacial water is brownish, since it carries lots of sediments that the glacial ice has carved off the earth. Gullfoss is called the "Golden Falls", since on a sunny day the water plunging down the three step staircase and then tumbeling in two steps down into the 32 m deep crevice truly looks golden.
