Situated in Jökulsá á Fjöllum in nothern Iceland, not far upstream from Dettifoss, is another beautiful waterfall called Selfoss. The Jökulsá á Fjöllum River is fed by the Vatnajokull Glacier, Selfoss is not as spectacular as Dettifoss but is noted for its horseshoe shape and power.

Just 12 meters high, Selfoss spreads out well over 100 meters or more depending on the season. In the summer when glacial melt is high the flow over Selfoss can spread out for quite a distance.
