Skógafoss waterfall on the river Skógá lies in the southern part of Iceland. The waterfall was created on the former coastline rocks. Over the millennia, the coastline was retreating deep into the sea and now the old cliffs define a clear boundary between the mountainous land and the old sea basin. The Skógafoss is 25 meters wide and 60 meters high and is one of the largest waterfalls in Iceland. It is associated with the legend of the treasure, hidden in the cave behind the waterfall by a Viking, who was the first to settle in the area. Reportedly, only a single ring survived from his treasure, the rest disappeared, and so far nobody knows where it is. The ring, however, can be seen in the local museum.
