Rh was said to have measured 3′ with interstratitied clay seams and to have furnished 50 to 100 tons of hemititehematite [sic] or altered fossil ore. Both these localities are close to the Oliver township line.

Near Galloway Gap about 2½ miles further west the sand vein was opened 10 inches thick on the property of Geo. Wharton and contained mostly soft ore.

The Ore sandstone and fossil ore beds are again exposed at the extreme south western corner of the township south of the Ochre mill, where the river has cut the magnificent section in the Clinton and Salina rocks. The Ore sandstone dips 56° northwest here and is about 15′ thick, separated by shales from the Danville ore beds which are here contained in a calcareous and fossiliferous rock 4′ thick. The upper bed is 14 inches thick, but very lean, and the two lower beds occur in two calcareous bands 20 inches thick, divided from each other by a thin band of shale and totally worthless as ore.

The Sugar valley north of this Ore sandstone terrace is composed of similar rocks found occurring in Kansas valley and long Hollow, and give rise to the same soil. The road up this valley from the Ochre mill is almost entirely through lime shales of the upper Salina formation, frequently so made up of good limestone beds as to be mistaken naturally for the next higher formation, No. VI. Indeed some of the beds are so massive as to create a subordinate ridge flanking the main Oriskany ridge further north, and dipping at angles of about 55° to the northwest.

The road keeps in these shales for nearly two miles to the new road leading from Harshberger’s to the school house on the ridge, which road shows but a very poor exposure of the Lewistown limestone formation and mainly cuts through a mass of sandy slates and shales on the south flank of the ridge underlying the Oriskany sandstone of the crest. This sandstone is 30′ to 40′ thick and is well exposed in the north leg of the synclinal dipping S. 50° E. 55°-60°.

This synclinal is wholly local and contains a narrow strip of No. VII creating a rugged hill about two miles
