carries any good beds outcropping on the north flank quickly under cover.
G. C. Moyer has the first quarry in this ridge west of Freeburg. located just at the bend of the road leading over the ridge from S. G, Hilbish’s farm. It has been idle for years and was only developed to a limited extent, showing a cut about 50′ long in which 35′–40′ of limestone is exposed on a dip of S. 5° E. 70°. This steep dip and the covering to be removed in working, probably led to its abandonment. The opening is in the bottom members of No. VI and the stone is thin bedding and shows some cleavage.
S. Hillbish’s quarry is perhaps three-quarters of a mile further west along the ridge, about 100 yards south from the road and worked only for local farm use. It shows some fair stone in thin beds near the bottom of No. VI on a 65° S. dip.
John Hepner’s old quarry is situated at the base of the hill west of the road leading over the ridge and about 2 miles from Freeburg. It was originally opened in the upper Salina lime shales and finally passed through these by a narrow cut into the bottom members of No. VI, which show shaly even yet and rather impure. The dip is about 30°, S. 10° E. and the stone lean and poor.
West from here to the Perry township line, there are no other quarries. The ridge apparently declines in height, owing to the rise of the floor of the Klopperdale valley to the north, between this ridge and Shade mountain, and whose summit is not far from the Washington—Perry line, The Limestone Ridge crest from Hepner’s quarry to the Perry township line is still well wooded with chestnut and oak timber, and is only slightly cultivated along its northern flank to the width of one field.
The Devonian rocks No. VIII are not well exposed. The Hamilton slate and sandstone however, make as usual a sharp-crested and prominent ridge, running parallel through this township to the Firestone Ridge, and separating the Firestone and Knight’s valleys. It contains some rather massive sandstone beds upon an average dip of about 45°, S. E., the hill containing them declining westward.
