Gullfoss, The most famous waterfall in Iceland
Gullfoss is in the river Hvítá (white river), which has its origin in the glacier lake Hvítávatn (white river lake) at Lángjökull glacier about 40km north of Gullfoss.
About a kilometre above the falls it turns sharply to the right and flows down into a wide curved three-step "staircase" and then abruptly plunges in two stages (11 m and 21 m) into a crevice 32 m (105 ft) deep. The crevice, about 20 m (66 ft) wide, and 2.5 km in length, extends perpendicular to the flow of the river. The average amount of water running over this waterfall is 140 m³/s in the summertime.
