center of the Finney syncline. The Claysville limestone occurs in a 
small area occupying the high knob at the water tank. The exact 
thickness of this bed was not determined, but limestone was seen 
outcropping through a vertical distance of more than 20 feet, some 
of the layers being 1 foot or more in thickness. The Prosperity lime¬ 
stone is much thinner and occurs in a very poor exposure about 40 
feet below the Claysville limestone. 
Upper Washington limestone and coal and Donley limestone .—This 
group of beds lies from 80 to 90 feet above the Middle Washington 
limestone at most of the locations mentioned above. In the northern 
portion of the township the Upper Washington limestone shows at 
North Buffalo Church and on the ridge road both to the east and west 
of this place, also at the road forks east of the township line three- 
fourths of a mile southwest of the church, and again well up toward 
the top of the hill east of the road forks at the head of Pleasant 
Valley. This limestone also outcrops on the Buffalo and Coffeys 
Crossing road at the top of the hill east of Pleasant Valley. At this 
place the Upper Washington coal appears to be in two sections, at 3 
and 15 feet above the limestone. Opposite the pump house on the 
Washington and Coffeys Crossing pipe line some of the white beds of 
the Upper Washington limestone show, and at the foot of the hill the 
Jollytown coal and Middle Washington limestone are poorly exposed. 
A good section of the Upper Washington limestone and associated 
beds may be seen near the west end of the tunnel under Sugar Hill 
and also on the road southward from Coffevs Crossing. Southward 
from this point the outcrop lines of these beds rise to the Washington 
anticline and are exposed on the road south of South Buffalo Church 
and on the road leading to Lagonda up the middle fork of Buffalo 
Creek near the top of the divide. In the southwestern portion of the 
township the Upper Washington limestone outcrops at the tunnel 
east of Claysville and on the road northward from the National 
pike 1 mile east of town. 
Jollytown coal and Middle Washington limestone. —On the road to 
the north from North Buffalo Church the heavy yellow layer of the 
Middle Washington limestone is prominent in outcrop, and it is also 
exposed on the road to the east from the head of Pleasant Valley. At 
both these places the Jollytown coal is in two benches of 6 or 8 inches, 
separated by 15 feet of yellowish shale. The coal is 94 feet above 
the Washington coal and about 58 feet below the Upper Washington 
limestone. In Pleasant. Valley these beds cross the Buffalo and 
Coffeys Crossing road about 125 feet above the stream. The Middle 
Washington limestone is present on both sides of the valley of the 
middle fork of Buffalo Creek to its source. On the west fork of 
Buffalo Creek these beds are exposed to the township line, and on 
the first road to the west north of the National pike on this creek a
