IX. THE STRANDFLAT ALONG THE COAST 

 FROM SOGNE FJORD TO X'IKTEN. 



The Region of Søndfjord, Nordfjord, and Stad. 



The Norwegian west coast in the reg^ion of Askevoll and Floro north 

 of Sogne Fjord has a distinctly developed strandfiat in the shape of 

 numerous low islets, skerries and sunken rocks, and in many places there 

 is a low foreland in front of the mountainous coasts of the higher islands 

 and the mainland. The rocks are here Silurian schists and later (upper 

 Silurian and Devonian) sandstones and conglomerates; and in some few 

 places (near Askevoll and on the southern side of Bremanger Land) 

 granite. I have not had an opportunity of investigating the strandfiat 

 in this region. By a study of the charts of the coast one will notice that 

 in many places the submerged platform with shoals and rocks is more 

 widely developed in this region than outside the coast farther south. 



Dr. Reusch gives [1901, p. 189J an illustrative drawing of the narrow 

 strandfiat (10 metres above sea-level) at the foot of the steep mountain 

 side on the outer coast of Askroven Island in Sondfjord. Small cirques 

 with nearly flat floors have there been carved I)y the shore-erosion into 

 the mountain sides. 



North of Bremanger Land the coast is built up of Archæan recks, 

 and the strandfiat is less conspicuous. 



Neither on nor outside the high Stad Promontory are there indi- 

 cations of a strandfiat, excepting perhaps a few sunken rocks. In this 

 respect the Stad Land forms an exception from almost the whole rest of 

 the west and northwest coast of Norwav. 



Along the coast northeast of Stad Land there is again a strandfiat 

 consisting of a submerged platform with numerous skerries and rocks, 

 and often a low foreland on the islands. The rocks are presumably 

 Archæan. 



The Region of Ålesund. 



The high islands Godoi and \'alderoi, outside Ålesund, have the 

 typical shape of a hat swimming on the water, the low strandfiat forming 

 the flat brim above sea-level (Fig. 105). This shape, which was already
