IV. Litt om Jutulhugget

Abstract

The Jutulhug (\"The big Troll's Notch\") is a cleft or canyon situated in the central part of Southern Norway under 62 degrees N. As our somewhat schematic drawing on p. 4 shows, it is situated in a wide saddle between the valleys of the Glomma (in the background) and the valley of Tysla in the foreground). The length is about 3 km, the depth is up to about 200 m. The rock is sparagmite (feldsparbearing sandstone) with its strata lying almost horizontally; it is much fissured. To the right side of the large cleft is seen a smaller one \"The little Jutulhug\". The floor of this consists of moraine. In the bottom of the large one is also some morainic material visible; but for the most part it is covered by debris from steep walls. Before it are roches moutonnees. In the foreground are seen moraines, the largest one has the name Raneggen. It has been asserted that this particular valley, so unexpected among the smooth forms of the country around it, has contained a river running from an icedammed lake in the Glomma valley. In the opinion of the author the \"jutulhug\" has been carved out partly by running water in a remote part of the pleistocene; but a local glacier has later done a good amount of work by plucking at the fissured rock and depositing the moraines before the cleft.
