COAL OF CAPE LISBURNE REGION. 183 
Cape Dyer field. — A third area of these coal-bearing rocks reaches 
he coast south of ('ape Dyer, where the coal beds are exposed in a 
ow cliff which is nearly continuous from Cape Dyer to the high bluff 
ailed the Ears, a distance of about 1^ miles. 
Cape Dyer is about 16 miles south of Cape Lisburne. Seen from 
he north it appears as an isolated butte standing out in the sea, the 
uul hack of it being much lower. The coal-bearing rocks probably 
onnect across back of the high point with the area above mentioned, 
ou th of Cape Lewis. 
The coal-bearing rocks consist of black shales and slates interbedded 
vith limestone. At the north end of this exposure they overlie the 
missive sandstones of Cape Dyer with apparent conformity. At the 
iouth end of the exposure the sandstones overlie the shales, the con- 
ict relation being a well-defined thrust fault. Where exposed in the 
sea cliff the shales and interbedded limestones are very much crumpled 
md often faulted. Coal beds outcrop at several places, but it is 
mpDssible to determine their number, since some of them may be 
epeated. The largest bed seen measures 40 inches and dips south- 
ward at an angle of 50°. The Coal is more or less crushed and only 
mall pieces can be obtained from the croppings. 
Only one of the other beds presented a measurable exposure — a bed 
L foot thick, about three-fourths of a mile south of Cape Dyer. The 
oal from this bed was obtained in large pieces. Mr. S. J. Marsh 
reports that in 1900 a schooner on which he was a passenger took 
ibout a ton of coal from this place for use in the galley stove. There 
ire no developments and no indications that the coals have been 
worked. Development will be difficult and mining will be expensive 
in this area on account of the disturbed condition of the beds. 
Kukpuk River.- — Coal beds probably of Paleozoic age outcrop on the 
Kukpuk River, about 15 miles from its mouth. These have not been 
examined by the writer, though the occurrence of the Paleozoic coal- 
bearing formation here comes within his observation. Should coal be 
developed on this river, Marryat Inlet could be used as a shipping- 
point by light-draft boats. 
Cape Thompson. — Similar coals have been reported from Cape 
Thompson, about 10 miles south of Cape Lisburne. The Paleozoic 
rocks are known to extend to Cape Thompson and, seen from a dis- 
tance, the cliffs appear to contain slates similar to those of the coal 
formation, but the locality has not been examined by the writer. 
inland extension of Paleozoic coals. — Nothing is definitely known of 
the occurrence of the Paleozoic coal-bearing rocks beyond a point 15 
miles from the sea on Kukpuk River. From descriptions of Noatak 
River, given by S. B. McLenigan, it seems possible that the crum- 
pled shaly rocks of this series may be exposed in the canyon of the 
Noatak, which is probably about L20 miles east of Cape Thompson.
