358 WHITE AND SCHUCHERT—CRETACEOUS SERIES OF GREENLAND. 
at Kook Angnertunek. The invertebrate fossils found here are iden- 
tical with those of the locality just mentioned and belong to the Montana 
formation, or the Senonian of Europe. The Tertiary basalt descends here 
to 1,480 feet above tide, and a few feet beneath it Steenstrup observed a 
previously described stratum of graphite, occurring under conditions 
similar to those attending the upper graphite at Kaersut. 
Beyond Niakornat the sedimentary series dips rapidly and disappears 
west of Iterdlak. Then fora long distance the basalt forms the sea front, 
in precipitous cliffs streaked with red ferruginous bands. Throughout 
the western coast of Nugsuak peninsula the Tertiary basalt appears to 
have a general westerly dip. Basalts tower up along the shore, or in 
cliffs some distance back of the beach, all the way around the outer 
portion of the peninsula to near the native village Nugsuak, at its ex- 
tremity. On the south coast, east of Niakornarsuk, it occurs in high 
precipices over which the smaller streams fall in cascades for hundreds 
of feet. Nevertheless sandstones and coal-bearing shales of Tertiary 
_ (“Miocene”) age are reported from the valley back of Iterdlak, the van- 
ishing point of the Cretaceous on the north shore, and near Nugsuak. 
At Ifsorisok, a place in the interior nearly midway between the two last 
named localities, Nordenskiold also obtained Tertiary fossil plants. At 
Natdluarsuk to the southeast of Nugsuak, Nordenskiold and Steenstrup 
found Tertiary coals and sandstones between 1,300 and 1,700 feet above 
tide dipping 10° to the west, with both floor and cover of basalt. Again, 
some distance east of Niakornarsuk, within the western entrance to the 
Vaigat, the buff beds of the Tertiary are seen in the cliffs near the shore. 
PRINCIPAL FOSSILIFEROUS LOCALITIES OF THE SOUTH SHORE OF NUGSUAK 
PENINSULA 
The Cretaceous on the south side of Nugsuak peninsula first appears 
on the coast about a mile west of Alinaitsunguak. Here occur about 
600 feet of buff, more or less coarse sandstones, dark coaly or smutty 
shales, and laminated thin sandy shales streaked with carbonaceous 
layers. A few dikes and intrusive beds of Tertiary basalt traverse the 
Cretaceous series, which is capped by a fortress-like mountain of ba- 
salt. The sedimentaries dip about 15° to the eastward and pass beneath 
tide level within a mile. Only fragments of plants were found by the 
writers at this point. The material collected here by former visitors was 
pronounced by Heer* to belong to the Atane series. 
Ata (Atane).—Ata, the type locality of the Atane series, the eddie of 
the three divisions of the Greenland Cretaceous f established by Heer, 
is situated about 18 miles east of Alinaitsunguak. Here the principal
