The strike at this point is N. 65° E. The roof of the seam dips 
60° NW, the floor 78° NW. 
About 100 yards northwest of this point a seam containing about 
3 feet of clean coal has been exposed. One mile northwest, at what 
is known as Doyle Camp, a coal 20| feet thick is exposed. The strike 
of the roof is N. 10° E., of the floor N. 30° W. ; the dip is from 75° 
to 85° E. Both roof and floor are very irregular and the coal has 
been found to be entirely cut off by a fault. 
Several seams have been opened near the headwaters of Shepherd 
Creek, of which the most promising is the Charlotte seam, on the hill- 
side southeast of Lake Charlotte.

The same seam has been opened again about half a mile south of 
this point. The coal in this seam is firmer and should stand shipment 
with less crushing than any other seen by the writer in this field.

The strike at this point is N. 20° E., the dip 65° NW. The open- 
ing is on the west side of the valley of Shepherd Creek, at an ele- 
vation of about 200 feet above Bering Lake. 
The region adjoining the north shore of Bering Lake has been ex- 
ploited to a considerable extent during the past season and a small 
amount of coal mined for local use. The seams so far discovered in 
this region are smaller than those described from other parts of the 
field. 
The high ridge between Lake Kushtaka and Shepherd Creek con- 
tains a large number of seams. There are probably at least 20 of 
these seams which are 5 feet or more in thickness and several which 
are over 20 feet thick. 
The western slope of this ridge is drained by Queen Creek and 
other branches of Carbon Creek. Queen Creek has cut into the crest 
of a sharp anticline, which is probably faulted on its southeastern 
flank, and on both flanks of which coal seams are exposed. The
