DETAILED GEOLOGY OF CLAYSVILLE QUADRANGLE. 169 
few feet above the creek valley. The Jollytown coal, which outcrops 
in several places along the road for half a mile, rises steeply to the 
west. Southward along Buffalo Creek from the -township line the 
Middle Washington limestone is barely above the creek. It out- 
crops at the road forks near the mouth of Sawliill Run and in the 
west bank of the creek at the next fork of the road to the south. On 
the road to the southeast from this point the limestone again outcrops 
at the next road forks. On Robinson Run the Middle Washington 
limestone does not outcrop north of Good Intent, but at the forks of 
this run just west of the point where it crosses the township line 
between East and West Finley the dolly town coal barely comes to 
the surface in the road at the south end of the bridge. The coal here 
is unusually thick for this bed, showing the following section:

On the creek road to the south of Good Intent a section of the rocks 
from the Donley limestone to about the horizon of the Middle 
Washington limestone was obtained, as follows:

Limestone in two or three thin layers, embedded in blocky brown shale; 
limestone whitish in color, dark gray to steel blue on fresh fracture— 1 G 
Shale below to creek bed. 
Just beyond the south boundary of the quadrangle, below the junc- 
tion of Templeton and Rocky runs, the Middle Washington limestone 
outcrops in the stream bed. On Wheeling Creek a coal bed, doubt¬ 
fully considered the Jollytown, was opened years ago on the south 
side of the run about three-fourths of a mile from the west border of 
the quadrangle* near the east edge of the Frazer farm, but at no 
other point in this basin was either of these beds found in outcrop.
