The mines on the deposits in the limestone were known as the Pike's Peak and Furnace mines. (See page 227.) The vein in the Hill mine was opened for a distance of 1,800 feet along its length before 1868, and already at this time considerable ore had been removed from its southern end, on the hill, south of the furnace. The mine was not operated between 1868 and 1873. Later (in 1879), however, it was reopened southwest of the old openings and was worked extensively in 1879 and 1880. It was finally abandoned in 1882 because of its increasing leanness. The vein can be traced southwest from the shaft of the Trotter (zinc) mine parallel to the zinc vein and only 40 or 50 feet from it across the Wallkill River and along the side of Mine Hill, for a distance of 1.25 miles. It is very near the contact between the gneiss and the Franklin limestone, and is in some places partly within the latter rock. Its dip is about 500 southeast, corresponding with the dip of the west leg of the Franklin zinc deposit. Much pegmatite is interbanded with the gneiss associated with the ore, and in a few places it cuts across the gneissic foliation. Allanite and magnetite are present in some of this pegmatite, and garnets of various colors occur in the limestone near the ore...
