The Lateglacial and Postglacial Upheaval of Sogne Fjord. 



Let us roiiipari' llic heights of the Xorwej^'ian strandflat with those 

 of tlic raised latc\i;lacial ami ijoslijlacial slnjrc-lines. 



In Sof^nc i'jonl tlie rollou iii;^- aliitudes of ihe lower level of the 

 emerg'cd strandflat were found: 



The measured altitudes of the upper level of the emerged strandflat 

 may indicate a similar rise of altitude from the inner parts of Sogne Fjord 

 towards the outer coast. We found it to be aljout 25 metres on \>garnes, 

 26 metres on \'angsnes, on Matsnes, and possibly on Rutlctangene, 33 to 

 40 metres on Radoi (according to Ahlmann), &c. 



Prov'ided that these olxservations be correct, and tliat the difference 

 be not due to glacial erosion, the strandflat has consequently been some- 

 what more raised near the outer coast than further inland, as was 

 previously mentioned. 



The upper limit of the lateglacial and postglacial submergence (or 

 upper marine limit) in the region of Sogne Fjord can only be traced by 

 the highest raised terraces. J. Rekstad [1905, 1906, 1907, 1910] has found 

 the following heights: 



Let us assume that the isohasc (i. c. line of equal postglacial upheaval) 

 for I/ metres (i. c. the height above sea-level <-)f the lower level of the 

 emerged strandflat near the outer coast) passes across the middle of
