DETAILED GEOLOGY OF CLAYSVILLE QUADRANGLE. 171 
Upper Washington coal is less than 6 inches thick. Near the first 
road fork northeast of this location the Upper Washington lime¬ 
stone crops out on the road to the west, and also on the road to the 
east toward Van Buren. About half a mile east of this point the 
Upper Washington limestone has been quarried on the east side of 
the valley just above the road. Here it is 42 feet lower than at the 
last outcrop mentioned. Farther south it is exposed on both sides 
of this run to a point a little beyond Van Buren, where, the dip to 
the south is so abrupt that it is carried under cover near the town¬ 
ship line. At the Crossroads schoolhouse, 2 miles east of Van Buren, 
the white ledges of the Upper Washington limestone, which show 
black to dark mottle on fresh fracture, are only a few feet above the 
run, the top of the Donley limestone being 22 feet higher. Up the 
run to the northeast from this location the Upper Washington, lime¬ 
stone rises at about the same rate as the bottom of the run to the 
first road forks, where it goes under cover. Just west of the Plymire 
well the Sparta coal shows 18 inches thick in the bed of the run. On 
the first road directly north of this point it occurs at the foot of the 
hill with at least as great a thickness. From the Crossroads school- 
house northward up the valley road the Upper Washington and 
Donley limestones outcrop at the first road to east. Farther upstream 
both the Upper Washington coal and the Sparta coal show in a num¬ 
ber of places as far as the Andrews well, south of Point Lookout. 
On the first road to the west from the Prosperity pike just south 
of Lagoncla the Upper Washington limestone crops out at almost the 
highest point on the road, and at the first road forks on the township 
line to the north the Donley limestone is exposed. Half a mile far¬ 
ther north the Upper Washington limestone and coal outcrop on the 
crest of the ridge, the coal being 13 feet above the limestone. From 
this point the outcrop line swings around the heads of the tributaries 
to Chartiers Creek to the exposure in Canton Township at the rock 
quarry south of Woodell. Good exposures of these beds are so 
numerous over this township that it is not necessary to describe all of 
them. A sufficient number of those in the basins of Chartiers and 
Tenmile creeks have been mentioned to admit of their identification. 
J oily town coal and Middle Washing ton limestone .—This group 
outcrops on the Prosperity and Pleasant Grove road on the hillside 
west of Tenmile Creek in front of the third house to the north. The 
coal is 18 feet above the heavy yellow bed of the Middle Washington 
limestone. On the Prosperity-Claysville road west of Tenmile Creek 
the heavy yellow bed shows at the head of the little run, where this 
road starts up the hill. The Jollytown coal was not seen at this 
place, but on the next road to the north it crops out 95 feet above the 
exposure of the Washington coal at the brick schoolhouse in the val¬ 
ley. In the basin of Chartiers Creek these beds outcrop at the foot
