| Abstract: | The tunnel through the mountain of Torghatten, in northern Norway, is generally regarded as a product of wave action. The tunnel is above the late Weichselian marine limit. Fresh looking polished bedrock that resembles subglacial ice-sculptured and meltwater forms, p-forms, occurs near the opening to the landward eastern side of the tunnel and inside. Most likely, the tunnel is a polygenetic formation. Storm action during deglaciations and also subglacial meltwater drainage and plastically sliding ice during glaciations have been active processes in the formation of the tunnel. |
