topography. A strong erosion can only take place at the 

 districts at the edge, where in this way deep lakes and 

 fjords are formed. On the other hand, frost weathering 

 soon attacks the higher peaks, which are not protected by 

 any ice-cover, and the pieces that break away are carried off 

 with the moraines of the ice. Such a mountain plateau differs 

 entirely from a peneplain resulting from river erosion, in that 

 deep valleys are by no means lacking, and have certainly been

present at every phase. Taking them all round these plateaus 

 form a special type among the land forms, probably limited to 

 areas that are or have been covered with ice. On the other 

 hand, to explain them as a direct result of the erosion of the 

 ice, does not seem to me to be possible. In real mountain- 

 chains, formed by late folding and upheaval, corresponding 

 plateau-areas do not seem to occur. 



The pictures flg. 27 and 28, though not very good, will 

 give us an idea about the scenery of those plateau-shaped 

 mountains in the inner fjord-regions.
