east, south of Igaliko, the border-line coincides with a large 
fault which runs in a direction from Е. М. Е. to М. $. W. Towards 
the north, in the low area between Tasiusak and Kagsiarsuk, the 
boundary, as shown by Steenstrvp’, is very irregular and its course 
is conditioned by the denudation: the underlying granite appears 
in almost all of the valleys between the numerous small sand- 
stone hills. But even here the boundary, from a more general 
point of wiew, may be said to be connected with a fault, which, 
however, runs at a little distance north of the actual border of 
the sandstone. The presence of this fault is indicated by the 
fact that while the northernmost outlier of the sandstone, at 
Tasiusak, is only slightly elevated above sea-level the granite 
rises to very considerable heights (1272 meters) less than three 
kilometers north of the border of the sandstone. Towards the 
west, the south-west, and the east, the sandstone areas border 
partly upon the fjords and partly upon the newer abyssal rocks. 
General aspect and surface relief. — The stratification is 
exceedingly well pronounced both in the sandstone and in the 
volcanic series and is on the whole almost horizontal or slightly 
inclined towards the south-west. The general aspect of these 
formations is therefore far different from that of the granite: 
plains and plateaus are the predominant surface forms. As the 
sandstone plains are situated around the middle and inner parts 
of the fjords where the summer climate is favourable to vege- 
tation, and as the plains are usually covered by a thin layer 
of morainic material or of alluvium, they produce fertile pastures 
or, in other places, copses of willow and birch which may be 
so dense that they are difficult to penetrate. Upon the plateaus 
and upon the terraced sides of the mountains the vegetation is 
scarce; the escarpments are quite bare and even at a long di- 
stance show the dark-red colour of the sandstone which gives 
a peculiar character to the entire scenery.
