Mánafoss, waterfall in the river Laxá. In the story of Þorvaldur víðförli (“the widely travelled”) it is said that the name comes from Máni the Christian, who caught so many salmon under the falls that he was able to prevent a local famine. Mánafoss is 2.5–3 m high, but rather difficult to reach because of ditches. South of Sauðanes are the Kolkumýrar marshes, grassy pools with low hills in between.
