twccn 30 and 40 metres, or in s(jine places {perhaps between 26 anrl 35 

 metres ahfne the sea — and a Unver level at about 15 to 18 metres above 

 the sea. In most places in these regions the upper level comprises the 

 greater part of the area of the strandfiat. The lower level extends near 

 the shore, is more even, and is obviously of younger age than the upper 

 level. Jn the region of Stavanger, this lower level is of comparatively 

 wide extent, especially where the rocks are phyllite and chlorite schists, &c. 

 which have comparatively little power of resistance to erosion. 



In tlic region of Smolen, IJitteren, and Froia (Fig. 107) the emerged 

 strandfiat has probably also two levels: an upper level about or higher 

 than 30 metres above the sea, and a lower level lower than 20 metres 

 above the sea. The lower level is here of a comparatively greater extent 

 llian in tlic above mentioned region of the west coast. It compri.ses the 

 most part of Smolen, and a great part of Froia, and is also widely extended 

 along the north coast of Hitteren. 



Along the coast of Helgeland the lower level of the emerged strand- 

 flat comprises the greater part of its area, especially in regions where 

 rocks with comparatively little power of resistance to erosion prevail. 

 On Donna and Heroi it forms very even planes at altitudes of 8 to 10 

 meters above the sea, and in some parts of the islands even lower. This 

 low plane of about 10 metres seems to be of very wide extent on the 

 many islands of Helgeland. 



The upper level at about 30 metres, or between 30 and 40 if it exists, 

 is at any rate of very small extent in the region of Helgeland (cf. the maps 

 Figs. 1 13 and 114). 



On Lofoten and Vesterålen the emerged strandfiat has probably also 

 two levels, and the upper level, perhaps at about 30 metres, seems to be 

 of a greater extent, c. g. on Hasseloi, than in Helgeland. The lower level 

 is well marked on the small islands along the coast (see Figs, i and 2). 



The siibiiierged Strandfiat of Norzvay. 



Along the west coast of southern Norway south of Sogne Fjord 

 there is not much of a submerged strandfiat. There are numerous shoals 

 sunken rocks here and there, at somewhat varying depth, but there are no 

 well defined platforms with horizontal planes. 



Along the coast between Sogne Fjord and Stat, there are more indi- 

 cations of a submerged strandfiat in the shape of small submerged plat- 

 forms and groups of shoals and sunken rocks often far out to sea. The 

 soundings given in the charts of this coast are not sufficiently numerous 

 for a study of the shape and topography of these platforms. Their depths 

 seem to vary somewhat, but are to a great extent less than 10 metres 

 below sea-level.
