Traces of a similar plain of marine ^emulation liave also been ob- 

 ser\(.'<l hy I loel north of l'"J)eltofl llarhour in Cros.s P^ay, hut it was there 

 hint;- at a lower level of about 150 metres above the sea. 



( )n the east side of Amsterdam Island I observed indications of what 

 may be an ancient platform which 1 estimated to lie at a level somewhat 

 hit^hcr than 150 metres (Vi^. i4^>). On the southern Norway Island there 

 is also a plateau in a similar height (see Fig-. 8). But as these platforms 

 are cut in more resistant rocks (granite and gneiss-granite) they may 

 be older. 



Inside the low and level strandfiat at \'erleegen Hook the mountain 

 rises to a very flat plane with a similar altitude. As, however, the inner 

 margin of this plane is not marked by any rleclivity, and as there is a quite 

 gradual transition from this plane to the general mountain plateau inland, 

 without any marked difference, it may here most probably be a part of 

 the raised ancient level mountain surface, that extends southward over 

 all the land east of Wijdc Bay. 



As was mentioned above (p. 199) A. Hoel [1922] and W.Werenskiold 

 [1920] have found several horizontal shelves or plateaus at various high 

 levels along the coast in southern Spitsbergen near South Cape. There is 

 one shelf at about 40 metres above sea-level, another at about 80 to 100 

 metres. This platform is especially well developed. It is in some places 

 several hundred metres broad, and is widely extended along the south coast 

 of the land, inside the low plain of the strandfiat, which is there very broad 

 (see Fig. 134). Farther north towards Horn Sound this platform is per- 

 haps somewhat lower, about 70 metres. 



There is one shelf, somewhat imeven, at 220 metres, and then a 

 fairly broad and conspicuous one at 340 metres above the sea, on which 

 Hoel observed many pebbles and shore boulders. 



It is indeed strange that shore formation of so recent date, that the 

 pebbles have not even been removed by glaciers, occur at such high alti- 

 tudes so near the southern end of the land. 



It shows on the one hand that there has been very great vertical 

 movements of the crust in this region relatively recently, and on the other 

 hand that the shore erosion must be so effective in this region, that in 

 the rocks of little resistance broad shore platforms can be cut in relatively 

 short time during temporary depressions of the land.
