DETAILED GEOLOGY OF STEUBENVILLE QUADRANGLE. 95 
Ames limestone .—The Ames limestone caps the highest hills just 
east of New Cumberland. A well-developed outcrop was found on 
the small butte east of Chelsea. The elevation of the limestone 
remains about the same to a point near the middle of the township, 
whence it dips steeply to the southeast. On North Fork of Kings 
Creek it is only a short distance above the stream bed. The outcrops 
are usually prominent throughout the township, except on Hol- 
bert Run. (hi this stream, although float was encountered, the bed 
was not found in place. 
Finley coal .—The outcrop of the Finley coal occurs in the river 
hills and also on the north fork of Holbert Run. 
Roger coal .—The Roger coal has been opened for mining east of 
New Cumberland and Blaekhorse, also near the intersection of the 
different forks of Holbert Run. The coal has a thickness of about 3 
feet and is embedded in a soft brown shale. 
Lower Kittanning coal .—The Lower Kittanning coal and its under¬ 
lying fire clay is opened for mining back of New Cumberland and at 
Blaekhorse. Its outcrop can be easily followed along the river. The 
distances between the coal beds of the Allegheny formation and 
the Ames limestone are given under Knox Township, Jefferson 
County, Ohio (p. 89). 
BUTLER TOWNSHIP, HANCOCK COUNTY, W. VA. 
Butler Township includes most of the West Virginia tributaries 
of Kings Creek. In the northern portion of the township the forma¬ 
tions are high, but they dip steeply to the south and southeast, so 
that the Pittsburg coal is caught in the higher hills along the south 
edge of the township and at Paris, Pa. 
Pittsburg coal .—The ridge between Kings Creek and New Cumber¬ 
land Junction contains the Pittsburg coal near the summit. The high 
ridge between North Fork of Kings Creek and Aunt Clara Fork 
catches the Pittsburg coal in two places. It is also exposed near the 
schoolhouse at the intersections of roads east of Aunt Clara Fork. 
The average thickness of the coal is a little less than 5 feet. It is 
overlain by a heavy sandstone and has been opened for mining in a 
number of places. 
IAmestone beds below the Pittsburg coal .—The interval between the 
Ames limestone and the Pittsburg coal contains two or three blue 
limestone beds, each about 1 foot in thickness. Their positions were 
not well established, though they may be said to be approximately 
20, 80, and 120 feet below the Pittsburg coal. 
Ames limestone .—The Ames limestone is especially well developed 
throughout the Turkeyfoot oil field and along North Fork of Kings 
Creek; also south of Kings Creek in the eastern portion of the town-
