FOSSILIFEROUS LOCALITIES—NORTH SHORE. 351 
sist: of thin, creamy or grayish, loose sandstones, or thin sandy shales, 
interbedded with numerous but variable carbonaceous strata, as at other 
localities. For along distance above the shore cliff the ascent is quite 
gradual. This, the Pleistocene terrace, was also observed at Pagtorfik, 
and is shown in our plate 25, figure 1. 
The Cretaceous beds are seen in the cliffs along the fiord dipping 
slightly but variably eastward, and it is highly probable that there is 
also a strong coastward dip as at the localities to the eastward. On 
approaching Ujarartorsuak (Shbesteensfjeld, Slibestensfield), the Av- 
krusat and Angiarsuit of Nordenskiold,* low hummocks of a bluish 
green highly altered basalt rise above tide level, and against these the Cre- 
taceous rocks apparently rest unconformably.

A little west of the highly altered basalt the nearly horizontal Creta- 
ceous series is suddenly interrupted. At this point throughout the com- 
plete height of the sea cliff the beds are crushed, broken, and dislocated 
for several hundred feet by a fault. Beyond this fault, which is dimly 
shown in the photograph, plate 25, figure 2, the strata consist of coaly 
shales, heavy sandstones, and sandy shales cut by three dikes. The com- 
position of the series and the relations of the beds are best shown in 
the photograph, plate 25, figure 2, and the accompanying profile sketch, 
figure 1, which, though necessarily hastily made, conveys an idea of 
the stratigraphic sequence. It extends from about 75 yards east of the 
fault to the ravine near the abandoned houseplace, a distance of about 
300 yards. It will be seen that the two westerly dikes are partially 
parallel with the bedding, which is not greatly disturbed, though the 
the local dips are plainly affected by the diagonally directed veins. In 
the face of the cliff near the fault the beds dip west about 45°. West of
