The Lateglacial and Postglacial Upheaval in the Hegion 

 of Nord Fjord. 



krkslad fouiHl Ikjo^ tlirii tlic j^n-ariicnt of |)ost^lacial upheaval is 

 much smaller in tlic (jutcrmost pari of Xor'l I'^jorrl than farther in. 

 Kaldhol's numerous measurements (1)\' k\cllin.L() of the upper heights of 

 the raised terraces in this re.y-ion, at ahout liundrc-il different places, have 

 shown this still more clearly [Kaldli<il. i';i2a . 



At t\vent\ iliffcrenl ])laces in the ouic^r coast zone. Ijetween the north 

 coast of the Slat I'c-ninsula and the south coast of Bremanger Land (and 

 iMoicn Island), Kaldhol's measurements of the upper limit of submergence 

 ^i\c heights between 15.2 and 17.7 metres above present sea-level (see 

 nia]) h'ig. 165). In most cases it is between 16 and 17 metres. At two 

 places, Revik on \agsoi and l'"orr]e on llremanger Lanrj, he founrl tlie 

 lieight to be 14.9 and 13.8 metres, but these values seem to be too low, 

 for at Vedvik, 2 kilometres north of Revik, the height was found to be 

 15.8 metres, and at Tysketveit close by, also on \"ågsøi, it was i() metres 

 (cf. Fig. 165). At Kalvåg on Froien Tslanrl, 10 kilometres south-west of 

 Forde and more seawards, the height was UkO metres, and at .'^teinset on 

 the outer side of the same island it was 17.3 metres. 



These heights about iC) ancl 17 metres and less than 17.7 metres are 

 found inland as far as Rugsund, inside the mouth of Xord Fjord, and 

 about 23 kilometres from the outer coast-line (cf. Fig. 165 )^ 



Kaldhol points out that the gradient of elevation is very gentle in 

 this outer region. Even if the height of 13.8 metres at Forde (Bremanger- 

 pollen) be used, and heights found farther seawards be considered too 

 high, the gradient will be no more than 0.26 per mille. It seems to me, 

 however, to be much more proba1)le, that the exceptional heights found 

 at Forde and Revik are a little too low. Kaldhol's observations give then 

 practically no gradient of elevation in this coastal zone. TJw land has here 

 been cicz'atcd about 16 or ly metres, keeping its horisontal leveL or at 

 least zi'ithout any appreciable tilting. 



It is striking what a perfect accordance there is between the height 

 of this horizontal upheaval and the height of the strandfiat in the outer 

 part of Sogne Fjord and in the coastal region outside, which I also found 

 to be about 16 and 17 metres. It is hardly probable that such a coincidence 

 is merely accidental. 



This seems in an unexpected manner to prove the correctness of our 

 assumption that this level of the strandfiat represents the level which the 

 shore-line had in this region before the last glacial period and before the 

 last submergence of the land. 



1 If the observations of 28.9 and 23.9 m. at Sandvik and Hammersvik, in the inner 

 portion of the Stat Peninsula, be correct, the border with the upper shore-line at 



heights less than 17.7 ni. may tie somewhat narrower in that region.
