On Wheeling Run the Upper Washington limestone comes to the 
surface three-fourths of a mile northwest of Elvilla. From this 
point the rocks dip westward so steeply that at the schoolhouse on 
the road to the south the Upper Washington limestone (with the 
Upper Washington coal 8 feet above) is 00 feet lower than at the 
first outcrop mentioned. The Donley limestone and Sparta coal 
occur at their regular intervals above the Upper Washington 
limestone. 
In the northeast corner of East Finley Township, in the basin of 
Buffalo Creek, this group of beds outcrops well up toward the heads 
of the tributaries of this stream. One-half mile north of Pleasant 
Grove, on the road to Claysville, the Donley limestone outcrops half¬ 
way down the hill. About 200 yards farther north, opposite the 
first house to the east, the lower section of the Upper Washington 
limestone appears. The rocks dip to the northeast, north, and north¬ 
west from this point. Northwestward the rocks dip to the bottom 
of the Mansfield syncline, where the Upper Washington limestone 
occurs in the bed of Sawhill Run half a mile west of the Sawhill 
schoolhouse. From this point northward the rocks rise gently to 
the next outcrop noted, which is on the road to Claysville, 200 yards 
north of the Sawhill schoolhouse. Within the limits of the Clavs- 
ville quadrangle to the south of Rocky Run this group of coals and 
limestone comes to the surface in a small area alone: the bottom of 
the deeper valleys. On the western fork of the road to the south 
from East Finley the Upper Washington limestone outcrops in the 
road on the boundary line of the quadrangle and in the bed of the 
stream a short distance north of this point. The white layer at the 
top of this bed is 14 inches thick, and on fresh fracture shows the 
characteristic black mottled color. Neither the Donley limestone 
nor the coal beds are exposed here. On Rocky Run the Sparta coal 
is unusually thick. It has been opened for mining in a number of 
places, but because of the great variations in thickness and quality 
of the coal, all of these banks have long since been abandoned. On 
the road to the north, one-eighth of a mile from East Finley, in an 
entry driven 80 feet into the hill, this coal is said to have varied 
from 6 inches to 34 feet in thickness. Those who have used it say 
that the best is somewhat rusty in color, makes a hot fire, and leaves 
a small amount of white ash. Where noted in outcrop the bed is 
from 6 to 18 inches thick and very friable, with a number of shale 
and clay partings. 
Jolly town coal and Middle Washington limestone .—These beds 
come to the surface in only a few places in these townships. On 
the road to the west from Buffalo Creek at the north boundary of 
East Finley Township the Middle Washington limestone is only a
