NORTH AND SOUTH FRANKLIN TOWNSHIPS, WASHINGTON 
COUNTY. 
The western half of North and South Franklin townships is 
traversed from northeast to southwest by the Washington anticline. 
The bottom of the Nineveh syncline, toward which the rocks in that 
half dip steeply, is just off the area to the southeast. The outcrop¬ 
ping rocks range from the Washington coal to a bed about GO feet 
above the Claysville limestone. 
Prosperity and Claysville limestones .—These limestones are ex¬ 
posed in small areas along the higher points of the watershed east of 
the basin of Chartiers Creek, from Point Lookout to Van Buren. 
They also occur in one or two places on the high ridge between 
Chartiers and Tenmile creeks. West of Tenmile Creek they outcrop 
in several places along the western side of the townships. The 
Prosperity limestone is the heavier in this area, has a bluish appear¬ 
ance, and shows dark blue on fresh fracture. The Clavsville is 
thinner and whiter, some of its beds resembling the Upper Wash¬ 
ington limestone. Few good measurements of the intervals between 
these beds and the Upper Washington limestone were obtained, as it 
was not necessary to use them in determining the structure of these 
townships. 
Upper Washington limestone and coal, Donley limestone , and 
Sparta coal. —A typical outcrop of the Upper Washington limestone 
as it occurs in this vicinity is exposed near the tollgate on the ceme¬ 
tery hill southwest of Washington. At this point the Donley lime¬ 
stone crops out in one or two heavy ledges at the highest point of 
the pike over this hill. The outcrop lines of these beds are clearly 
marked by quarries around the hillsides for some distance to the 
west, and also to the south as far as reservoir No. 3. On the east 
side of Chartiers Creek from reservoir No. 3 southward the beds dip 
gently, going under cover near the head of the stream. They 
reappear on top of the divide between Tenmile and Buffalo creeks, 
where all the members of this group are exposed, the Donley lime¬ 
stone only 25 feet above the Upper Washington limestone, with the 
Upper Washington coal between. The Donley is directly overlain 
bv a few inches of shaly coal, which may possibly be all that remains- 
of the Sparta bed, though this coal may outcrop still higher on the 
hillside to the west. To the south, along the western slope of Ten- 
mile Creek, the beds dip slightly for a distance, then rise slowly over 
the Washington anticline, then dip again steeply to the southeast. 
On the east side of the hill east of Tenmile Creek the Upper Wash¬ 
ington limestone is finely exposed and has been quarried for road 
material. On the road from Pleasant Grove to Lagonda, one-fourth 
mile northeast of Tenmile Creek, the Upper Washington limestone 
is well exposed just east of the residence of Mr. Tannis, where the
