mountain slope (Fig. 33). There are three low points with ridges parallel 

 to one another. The two ridges have exactly the same level, measured 

 to be 1 7. 1 metres above the sea. At this height there is a distinct plane 

 cut in the solid rock-surface. This plane lies a little lower on the western- 

 most point. But here a ridge rises to about 25.5 metres above sea-level. 

 A similar ridge rises to the same level on the middle point. 



The strandfiat at Alatsnes is relatively broad and extends a con- 

 siderable distance westwards along the coast of the fjord. Its surface 

 is scoured by glacial erosion (see Fig. 33 B). The projecting edges of 

 the rocks are rounded on the thrust-side or eastern side, and are more 

 angular on the lee side or western side (Fig. 33 B). But the surface has 

 on the whole the appearance of having been originallv formed by shore 

 erosion by frost, and not by glacial erosion. 



Further west at Brekke, west side of Risne Fjord, there is a verv 

 conspicuous strandfiat forming a distinct incision in the mountain side
