John Moyer’s quarry is the first opening, merely a small hole south of the new Grace Reform church.

J. D. Schrader’s quarry is the next, about a mile east on the west side of ‘the gap through the ridge and about 300 yards from the Musser valley road. It is a small opening, showing about 20′ of ribbed and roughly weathered stone at the bottom, and a 10′ massive bed on top, rather siliceous and not quarried, dipping 8. 18° E. 35°.

The quarry has long been idle and the kiln dismantled, and the opening is largely in the bottom portion of the formation. A somewhat larger opening, probably belonging to the same party, is located 100 yards east; but no larger or better section of limestone is exposed there, and it is also abandoned.

Henry Moyer’s quarry is 50 yards still further east, and faces the gap road nearly, still on the western side of the ravine, It is 80′ long, east and west, and 25′ wide, and in the center has been worked down on a belt of good blue stone, 20′ thick, to a depth of about 40′. The southeast dip is about 40° and the cleavage or joints in the quarry incline north-west 50°. Some excellent stone near the bottom of No. VI has been recently quarried and burned here. A section shows about as follows:

Top soil and slaty limestone, 6′–10′
Bluish gray bed; massive and fair quality, 10′–12′
Soft blue beds, thin seams, 20′
Hard blue beds at base, 10′

East of the gap road the ridge is largely eroded for about 300 yards, but soon forms a broad flat hill in the local synclinal already mentioned, which doubles the width of the outcrop.

Jacob Bingamen’s quarry is the first opened on this ridge, quarrying and burning lime for farm use in the neighborhood, and furnishing between 5 and 8000 bushels per year from one draw-kiln of a capacity of 180 bushels. Coal is hauled from Adamsbury on the railroad 6 miles distant, and costs delivered from $3.50 to $4.00 per ton, so that no very wide market for the products of this ridge could be expected.
