Cape Guissez in Cross Bay. 



Along- the shore east of Mount Grimaldi, on the east side of the 

 entrance to Cross Bay, northwards from Cape Guissez, there is a vertical 

 cliff of solid rock (see Fig. 142) which, according to Hoel's statement 

 [1914, p. 26], is about 20 metres high. The plain rises gently inland from 

 the edge of this cliff to the foot of the mountain where, according to 

 Hoel, it attains an altitude of about 35 metres above the sea. It is here 

 covered by more recent terraces of gravel, and the surface of the strand- 

 flat, cut in solid rock, is lower. Hoel estimates it to be about 25 metres 

 above the sea. 



Outside this shore, north and south of Cape Guissez, there is a 

 submerged platform, half a kilometre to one kilometre broad, or even 

 more, with depths less than 20 metres [cf. Hoel, 19 14, p. 40, Pi. XX\', il. 



Cape Mitre Peninsula and the North-western Part of Spitsbergen. 



On the south and west side of Cape Mitre Peninsula, west of Cross 

 Bay, there is a very flat and well developed emerged strandfiat. the 

 Dieset Plain ("Dieset Sletten", map Fig. 143), as has already been pointed 

 out by Hoel. It is 2 to 4 kilometres broad, and rises very gently from 

 the low shore to the base of the abruptly and steeply ascending mountains 

 (Fig. 144), at about 25 to 30 metres above sea-level. There are a good 

 many shallow lakes on this strandfiat. Towards the south it is continued 

 as a submerged platform, 3 to 4 kilometres broad and with depths less 

 than 20 metres. As regards the occurrence of the emerged strand flat 

 there is a striking difference between this peninsula and Prince Charles 

 Foreland. Here the strandfiat is well developed along the west coast, 

 while there is no strandfiat along the east coast of the peninsula, in Cross 

 Bay, except near Ebeltoft Harbour ("Ebeltoft Havn", Fig. 143). The 

 reason why there is no strandfiat along the coast north of Ebeltoft Harbour 

 is obviously that after the development of the strandfiat, Lilliehöök Fjord
