to east. In the map given by Dr. Rekstad ' he marks the height 

 as 328 feet a little to the west of Balestrand. In a later work " he 

 places the late-glacial marine limit at 377 feet at Vik, on the south 

 of the Sogne Fjord ; and in another paper 3 he says that the highest 

 terrace at Hovland on the Aardals Fjord (449 feet) apparently 

 represents the highest marine limit after the Ice-Age. Hovland 

 (Xatviken) is 15 miles south-east of Solvorn, so this agrees very 

 well with the 426-foot terrace at the latter place, and it clearly 

 belongs to this late-glacial series. 



This late date for the Solvorn terrace, together with other 

 evidence, makes it difficult to believe that the outlet of the Hafslo 

 Lake to Sogndal did not exist at the time of the deposition of the 

 Solvorn moraine. Thus there is a series of ice-markings on the rock 

 by the new road from Marifjaeren to Hillestad, a little north of 

 the latter place, and they point in a south-westerly direction : 

 that is, towards the present outlet of the lake and not towards the 

 Solvorn col. Moreover, there is evidence that a vast mass of ice- 

 passed down the series of fjords from Sogndal to the Sogne Fjord,, 

 for there are deep glacial grooviugs on Nordnres, south of Norum. 

 Church. 



I would suggest that, the Hafslo Lake being full of ice, the main 

 glacier coming down the Vejtestrands Lake and a tributary down 

 from the mountains north of Hillestad, and the main mass of ice 

 moving down to Sogndal and the Sogne Fjord, there was an over- 

 flow of ice and water from the left side of the glacier over the 

 Solvorn col and down towards that place. This view is supported 

 by the presence of masses of moraine-material on the mountain- 

 side above the shore of the Hafslo Lake, between the Solvorn col 

 and the Sogndal outlet. There is no reason why more than one 

 stream should not flow simultaneously from a single glacier ; in 

 fact, that is precisely what happens in the case of small recent 

 glaciers, and the fact that the Solvorn col is 100 feet above the 

 Sogndal outlet does not, I think, make a serious difficulty : for one- 

 river may have flowed in or over the ice, and the other beneath it. 

 In any case, I think it more probable that both outlets were used 

 during the late-glacial period and possibly simultaneously, than 

 that the Sogndal outlet has been deepened, as much as 100 feet 

 since the deposition of the Solvorn mass of sand and gravel.
