and is obviously very nearly the same as that which I found in the north- 

 western part of the Lindås Peninsula. But this surface may correspond 

 to Ahlmann's lower level which he found both at Manger and on Sæloi 

 (Hjelmen), where it was, however, lo — 14 metres above the sea, and 

 which he thinks, "does not show any inclination in any definite direction". 

 Fig. 51 is a profile across Radoi and the Lindås Peninsula from 

 Lyngøi and Forhjelmen (Fig. 21, no. Or and 62) in öigaren (in 60° 40' 

 N. Lat.) to Skårefjell on the mainland (in 60° 42' N. Lat.) east of Öst- 

 fjord. This profile demonstrates the remarkably level plane of the very 

 brt)ad strandfiat, above which the mountain sides rise abruptly. It also 

 shows how the plane of the strandfiat extends uninterupted and without 

 nny marked change in height across regions of different geological struc- 

 ture. Some of the hills surmounting the plane of the strandfiat are built 

 up of comparatively resistant rocks, e. g. Kaisås consisting of mangerite. 



Region of Bergen. 



In the region round Bergen the land is more mountaincjus than along 

 the coast farther north, and the strandfiat is much less developed, and has 

 not such great extent as in the region of Radoi and Lindås. But it is 

 quite conspicuous along the sides of the sounds and fjords in some places. 



At Salhiis, in the Salhus Fjord, north of Bergen, the strandfiat forms, 

 for instance, a well marked incision in tlie mountain slope (Fig. 52). 



Bergen is to some extent situated on a narrow strandfiat, which 

 extends more or less southwards through the valley to Fjosanger and 

 Nordåsvand. 



On the Faiic Peninsula, between Nordåsvand and Fane Fjord, south 

 of Bergen, the strandfiat has a wide extension west of the steeply 

 ascending mountains. Seen from the sea to the west (Fig. 53), it appears 

 very flat and conspicuous. A great many of the islands to the west of 

 Fane are also low and form parts of the strandfiat. 



In the region of Os at the southern extremity of tlie whole peninsula 

 between the Bergen By Fjord and Samnanger Fjord, the strandfiat is 

 well developed and sharply defined in the region of Rotingen (Fig. 54).
