 to the outer c(h^c of these suhmerj.^cd jjlatforms is in the region of 

 Christiansund about 12 or 13 kilometres. The submerged plateau of Grip 

 with nmiierous islets and skerries, outside C'hristiansund, may be especially 

 nient iontMl. 



These submerged i)lat forms ha\e uneven surfaces similar to those 

 of the platforms, just described, to the southwest. The CJrip Plateau 

 seems, however, to have in parts somewliat more level surfaces with more 

 distinctly defined edges. It may pro])al)ly be Ijuilt up of somewhat less 

 resistant rocks, like those of the Smolen Plateau to the ncjrtheast. 



The Region of Smølen, Hitteren, and Frøia. 



The region of Smolen, Hitteren, and PVoia is interesting because of 

 the complexity of the geological structure, and the unusually well developed 

 strandfiat which cuts horizontally through the various geological forma- 

 tions, frequently without any appreciable break in its level plane (cf. Figs. 

 108 and III). 



Especially on Smolen and its neighbouring islands (see the map 

 Fig. 107) we find the most perfectly developed plane of the emerged 

 strandfiat which occurs along the coast of Norway. 



Smolen island is 16 kilometres from south to north and 20.7 kilo- 

 metres from west to east. The whole of the island is one unbroken plain, 

 which is especially even in its northern part wdiere only two small hillocks 

 (Dyrnestuva and Måbergtuva) rise slightly above the plane. The height 

 of this almost perfect plane is 15 to 20 metres above sea-level. In the 

 southern part of the island the plain is somewhat more undulating and 

 a few isolated hillocks rise above it to 26 metres (Storsetberg), 33 metres 

 (Hoaåsen), 35 metres (Torshaug)* 39 metres (Rambergtuva), and one 

 even to 45 and 67 metres (Nelvikberg) in the southeastern corner. 



The northern part of Smolen consists of diorite with a belt of pressed 

 igneous rocks along the northwestern coast [cf. Schetelig, 1913]. In the 

 southern part there are various rocks, probably of Silurian agz [Reusch, 

 1914, Schetelig, 1913] with enclosures of a limestone probably of Ordo- 

 vician age [Holtedahl, 1914]. On the islands to the south of Smolen, on 

 Kuli Island, Edoi, &:c. there are conglomerate and sandstone, probably 

 Silurian.

 Island, Kuli Island, Smolen, and the small islets to the north, gives the
