ship. The bed was found on the summit of a small knob south of the 
ridge road 1 mile southeast of Kings Creek station. It could not be 
located, however, in the high knob directly east of Kings Creek sta¬ 
tion nor in the knob south of Kings Creek station and between Kings 
Creek and the river. Only one comparison of any value was made 
of elevations to determine the interval between the Ames limestone 
and the Pittsburg coal. This gave a result of 220 feet. 
Cambridge limestone. —In this township two outcrops of the Cam¬ 
bridge limestone were found, one in a small run northwest of Paris, 
Pa., and the other on the road from Paris to Turkeyfoot oil field. 
This bed is about 95 feet below the Ames limestone. 
Finley coal .—The Finley coal is of considerable importance, being 
mined about 1 mile southeast of Zalia station. It is accompanied by 
a heavy limestone below. 
Roger coal .—This coal outcrops along the river front back of Zalia 
and Kings Creek station; also at the iron bridge over Kings Creek, 
and from that place almost continuously up the creek beyond the 
Turkeyfoot oil field. The bed is about 3^ feet in thickness and is 
mined in a number of places, furnishing an excellent quality of coal. 
The interval between this coal and the Ames limestone does not 
remain constant, differing fully 75 feet between the Turkeyfoot oil 
field and the mouth of Kings Creek. The bed of coal is undoubtedly 
not parallel to the other strata of the formation. This peculiarity 
of the Roger coal has been noticed at other locations, and for that 
reason it is not a reliable stratum to use for careful structural work. 
Middle Kittanning coal. —The Middle Kittanning coal is at the 
same elevation as the wagon road from Holbert Run to the mouth of 
Kings Creek, where it is just above the grade of the railroad. 
Lower Kittanning coal. —The Lower Kittanning coal and its under¬ 
lying fire clay have been opened for mining at Zalia and to the south. 
This coal dips under the river at the mouth of Kings Creek. The 
intervals from this coal and the three preceding to the Ames lime¬ 
stone are given under Knox Township, Jefferson County, Ohio 
(p. 89). 
CROSS CREEK AND BUFFALO TOWNSHIPS, BROOKE COUNTY, W. VA. 
Cross Creek Township includes most of the drainage of Harmon 
and Cross creeks, in West Virginia. The small portion of Buffalo 
Township which reaches to the southern limit of the quadrangle 
will be considered in connection with Cross Creek Township. These 
townships present a geologic section from the Washington coal of 
the Washington formation to the Cambridge limestone of the Cone- 
maugh formation. 
Washington , Waynesburg , and Uniontown coals. —The Union- 
town and Waynesburg coals occur in a considerable area south 
of Cross Creek, and the Washington coal is present on the
