GENERAL GEOLOGY OF CLA YSVILLE QUADRANGLE.

near the pumping station of the Citizens’ Water Company. From 
this point the crest rises slowly to the southwest to a point about a 
mile west of Lagonda, where it culminates in a small dome. Thence 
the crest line changes its direction slightly toward the south and 
pitches again to a low divide, the bottom of which is at the point 
where this anticline crosses Tenmile Creek, 1^ miles northeast of 
Pleasant (trove. The top of the next dome is about three-fourths of 
a mile south of this village, near the corner of East Finley, Morris, 
and South Franklin townships. Continuing southward the crest 
pitches steeply to a point a little west of the Joint schoolhouse, from 
which it describes a sweeping curve to the south and southwest, leav¬ 
ing the quadrangle at a point almost directly south of East Finley. 
From the village of Gale southward the location of the crest is not 
clearly determined owing to the scarcity of recognizable outcrops. 
NINEVEH SYNOLINE. 
The Nineveh syncline, which lies to the southeast of the Washing¬ 
ton anticline, extends across the southeastern part of the quadrangle. 
It enters from the south, 2 miles from the southeast corner, and leaves 
the east border 2 miles directly east of Van Buren, near Cross Roads 
schoolhouse. Southeast from this trough the rocks rise again to 
the crest of the Amity anticline, which lies less than a mile beyond 
the southeast corner of the quadrangle. 
FINNEY SYNCLINE. 
Northwest of the Washington anticline is the Finney syncline, the 
bottom of which crosses the south border of the quadrangle 21 miles 
from the southwest corner, near the junction of Rocky and Temple¬ 
ton runs. Its bottom is broad and irregular at the south line of the 
quadrangle, but rises and narrows abruptly to the northeast, the 
greatest contraction occurring 1 mile south of Fargo, where a low 
cross fold, with an indistinct northwest-southeast trend, raises the 
bottom of the syncline sufficiently to form a small basin to the north. 
At the point where Buffalo Creek crosses the East Finley and Buffalo 
township line there is another shallow trough, and from this the 
bottom on the syncline rises 60 feet to the next basin, which extends 
from a point a short distance south of Coffeys Crossing to Woodell 
and a mile farther west. From the northeast end of this basin the 
bottom of the syncline swings northward in an almost direct line 
toward the northeast corner of the quadrangle, rising about 100 feet 
per mile until it dies out against the high, broad dome near this 
corner. Stevenson® calls this trough the Mansfield svncline, con- 
a Stevenson, J. .T., Second Geol. Survey Pennsylvania, Kept. K, 1876, p. 31.
