Several prospect openings and a well-constructed tunnel have been 
driven into the banks of Carbon Creek. The latter intersected two 
seams, the larger of which has a thickness of 8 feet of clean coal. 
This is not the same as the Carbon Creek tunnel mentioned above. 
The valley of Stillwater Creek and Lake Kushtaka has been shown 
to contain a great deal of valuable coal. A trail recently built north- 
ward from the western shore of Lake Kushtaka exposes 15 or 16 
seams. The writer has seen one seam on the west side of Lake Kush- 
taka which has a thickness of over 22 feet, and several others with 
thicknesses of from 8 to 15 feet. It is reported that a thickness of 
over 60 feet of coal was found in a tunnel in one of the valleys on the 
north side of Stillwater Creek. 
The following section is exposed in the west bank of Trout Creek, 
2 miles above its juncture with Stillwater Creek and 6 miles above 
the mouth of the latter :
