26 COAL RESOUECES OF THE YUKON. [no. 218. 
therefore, be considered Kenai. The coal contains much amber or 
fossil resin. Some specimens were almost one-half amber in grains 
distributed through the mass. In this respect they resemble the 
coals found on Washington Creek, in American territory. 
Analyses made of the samples from the 5-foot seam above described 
were made by E. T. Allen. They are as follows:

No coal has yet been mined on a commercial scale on Coal Creek. 
On the main fork of the creek the openings into the coal are low, and 
the dip will no doubt throw the coal below water level. Exploitation 
of the seams will therefore require hoisting and pumping, and a rail- 
road not less than 10 miles in length to carry the coal to the landing 
on the river. 
In working the Cliff Creek mine it is found that the frost in the 
coal extends to a depth of 150 feet below the surface. The unfrozen 
is of better quality than the frozen coal. 
Mission ( 'reek. — Mission Creek enters Yukon River from the west 
at the town of Eagle, 12 miles below the international boundary. 
The creek flows eastward and has a length of about 15 miles. An 
area of coal-bearing rocks from 3 to 4 miles wide extends back from 
the Yukon for a distance of or 7 miles on the south side of this 
creek. The northern and southern limits of this basin are fairly well 
known, but whether its western end is connected with the similar coal- 
bearing rocks reported to occur on Seventymile River could not be 
determined in the brief time at the writer's disposal. Attempts have 
been made to open coal mines within this field on American Creek and 
Wolf Creek, southern tributaries of Mission Creek. 
The coal seams of the Mission Creek field are contained in gray shales 
associated with conglomerates varying from incoherent gravel to hard
