348 WHITE AND SCHUCHERT—CRETACEOUS SERIES OF GREENLAND. 
able fossil plants were found more than 100 feet stratigraphically above 
the lowest bed seen at tide level. 
Nordenskiold, who published * the best geological section at Kook, was 
disposed to regard as Atane, or Upper Cretaceous, the beds at and above 
750 feet above tide. At this level he obtained some fragments of Sequoia 
fastigiata, an Atane species, which led Heer } toadmit the possible Upper 
Cretaceous age for the beds, though they were not so regarded by him. 
However, the absence of dicotyledons or other distinctively Atane species 
has hitherto left doubt as to the presence of the Atane series in this por- 
tion of the peninsula, and consequently as to the thickness of the Kome 
series. The collection made in 1897 at Ujarartorsuak fully establishes 
the existence of an extensive development of the Upper Cretaceous in 
the region of the typical Kome series. It is, accordingly, probable that 
not over 700 feet of Kome series is exposed at the type locality, and it is 
doubtful whether a greater development than 1,000 feet is anywhere 
visible. 
The horizontally bedded Tertiary basalt, overlying the sedimentary 
series at an elevation of about 1,500 feet, extends to 6,330 feet above tide 
at the head of the Sarfafik glacier, in the Kilertinguak peak, a few miles 
west of Kook. The basalts are therefore probably more than 4,500 feet 
thick in this region. 
Pagtorfik.—Between Kook and Pagtorfik (Pattorfik), the next westward 
of the richly phytiferous localities of the Kome series, the continuity of 
the nearly horizontal sedimentary beds is interrupted by several low — 
hillocks or ridges of the old crystalline rocks and by great accumulations 
of basalt talus. The stratigraphy of Pagtorfik, from which the first large 
collection of plants was obtained by Nordenskiold in 1870, and a second 
by Dr Nauckhoff ¢ in 1871, has been briefly described by the former § and 
by Steenstrup.|| The coast profile is more gentle here than in most parts 
of this region, on account of the Pleistocene terraces, which from here to 
Avkrusat are especially well marked (see photograph of terrace near 
Ujarartorsuak, plate 25, figure 1). Up to 100 feet above tide the slopes 
are largely covered with glacial and other detritus, and of light colored or 
greenish-gray basaltic sands, often hardened into a tuff-lke mass. From 
these terrace deposits several collections of fossil invertebrates have been 
made.4]
