Rh Tuscarora line, the No. VI limestone shows at the school-house dipping north only 25°, indicating the broadening of the main synclinal basin to the north. Inside the gap, just beyond the forks of the road to MeCoysville and Pleasant View, the Marcellus black slate shows in a small dome-shaped hill caused by the prolongation westward of the small synclicalsynclinal [sic] fold already described south of Pleasant View; and a little east of the forks these slates dip 80° N. W. and 20° S. E. The central portion of the valley south of Tuscarora creek is occupied by a high ridge of Hamilton shales and sandstone, which first begins to take shape west of Pleasant View.

At the ford north of Pleasant View and along the Beale township line the Lewistown limestone is well exposed in the North Limestone ridge in massive layers, dipping S. 36° E. 55°, showing some good beds of smooth dark gray limestone. The same rock is exposed lower down the creek.

This township lying immediately west of Beale and Spruce Hill and between Black Log mountain on the north and the Tuscarora mountain on the south, has a roughly trapezoidal shape only that the two parallel sides on the north and south sides of the township are made irregular by offsets in the township lines.

Thus the north township is formed by two lines making an obtuse angle with each other; the first a little over 2 miles long, extending from the south Medina crest of the Blue ridge across the Licking creek valley to the summit of the anticlinal knob of Oneida sandstone in Black Log mountain; the second line runs for 2½ miles along the north crest of the Black Log mountain to join the western township line. The latter is 8½ miles in length, running southwest straight across the Tuscarora valley from Black Log mountain to the summit of Tuscarora mountain. The east line, 9 miles long, is likewise straight, bearing a little southeast from Minehart’s gap in the Blue ridge to the summit of Tuscarora mountain, while the south line, in common with Perry county, runs 3 miles west along the Medina
