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 vallej's on the 
north side of Stillwater Creek. This was not exposed at the time of 
the writer's visit in 1903, but the following section was measured in 
the west bank of Trout Creek, 2 miles above its juncture with Still- 
water Creek and 6 miles above the mouth of the latter (fig. 9):

The strike is N. 40° E. ; the dip is west at an angle of 38°. 
The high ridge between Lake Kushtaka and Shepherd Creek con- 
tains a large number of seams. Probably, at least twenty of these 
seams are 5 feet or more in thickness, and several are over 20 feet thick. 
The western slope of this region is drained by Queen Creek and 
other branches of Carbon Creek. Queen Creek has cut into the crest

flank, and on both flanks of which coal seams are exposed. The coals 
in this locality are of extraordinary thickness, perhaps having swollen 
into pockets near the crest of the fold (fig. 10).
