"History tells us that in the year 1000, Þorgeir, chieftan of the Ljosvatn district, and Lawspeaker of the Althing, was entrusted with the momentous task of deciding whether Icelanders should adopt the Christian faith. When his decision was formally accepted, he went home and threw his statues of the pagan gods into the waterfall. Goðafoss (Waterfall of the gods) is said to derive its name from this event. It is 12 metres high. Skjálfandafljót is the country's fourth longest river."
