180 ALASKAN MINERAL RESOURCES IN 1904. [hull. 259. 
tion is not exposed in the sea cliffs, and the croppings in the interior 
are not well defined. Croppings of half a dozen or more coal beds, 
were seen south of a camp 10 miles east of Cape Sabine. One oa 
these which was well exposed was found to be over 4 feet thick. Thej 
beds strike N. 80° E. and dip north at angles varying from 20° to 40°.' 
Cape Beaufort field. — The occurrence of coal at Cape Beaufort, 40 
miles east of the Corwin Bluff, was noted by Mr. Collie seventy-five* 
years ago. At this point there is a hill 500 feet high, but the cliff is 
made up of Quaternary gravels, ground ice, and talus from the hill, so 
that there are no good exposures. In the hasty examination made 
last summer the croppings of no less than 4 coal beds were discov-j 
ered on this hill, but no measurable exposures were found. Mr. F. C. 
Schrader, who visited the locality in 1901, reported seeing a partially 
developed coal bed 6 feet thick one-eighth mile from the coast. The ; 
beds strike south 45° east and dip southwest at an angle of 20°. 
Inland extension — The present investigation was necessarily con-J 
fined to a strip a few miles wide along the coast, but, as has been 
already pointed out, the inland extension of the coal field can be 
reasonably inferred from topographic evidence. Residents of the] 
region who have made the trip from Point Hope to Cape Sabine, by 
way of the Kukpuk and Pitmegea rivers, report rinding coal at their \ 
camp on the portage between these rivers. This camp could not have 
been less than 20 miles inland and southeast of Cape Sabine. 
Character of Mesozoic coal. — Analyses which have been made of a 
number of samples of these coals indicate that the coals are noncoking 
bituminous and scarcely better than lignites. 
The average of the analyses of samples taken from six of the beds 
described is as follows:

It is reported that these coals have not given complete satisfaction 
for steaming purposes. Though they burn readily and produce steam 
quickly, they are of low specific gravity and are not lasting. It takes 
about double the amount of this coal, as compared with Comax coal, 
to maintain a given pressure. It burns with little smoke, but produces 
a large amount of ash and cinder. 
Conditions of mining and development. — There are no permanent 
developments or conveniences of mining at any of the places where 
coal has been obtained. When the mines were operated by the whal-
