Stóri-Dímon (Stóra-Dímon) is a lonely mountain standing on the flat plains in front of the Markarfljót river valley. The mountain formed during a volcanic eruption underneath a glacier for hundreds of thousands years ago. The surrounding has been flattened out by the Glacier river Markarfljót, and massive glacier outbursts related to volcanic activities for a long period of time.
Though the mountain is not big only about 120 meters high, then there is a beautiful view from the top of it.
To the north is the Glacier and Volcano Tindfjallajökull, to the east glacier Mýrdalsjökull and the volcano Katla, as well as the Glacier and volcano Eyjafjallajökull. And if you look south you should see the Vestmannaeyjar islands in front of the coastline, also a volcano.
So four volcanoes, and three glaciers, not to bad.
