Left at Roxbury Station, a dirt road crosses the railroad and turns into the property known as MINE HILL. (private property, visitors welcome, park car and proceed on foot; care should be taken to avoid hidden mine shafts), 0.3 m. The mine, which was originally opened in 1750 by prospectors who hoped to find silver, contains one of the few American deposits of siderite.The vein of spathic iron averaged about 8 feet in width and was uncovered for a distance of one mile. More than a million dollars were expended in developing the mine, which for 42 years was operated by the American Smelting Company. Ten tons of pig iron was the average daily output. Now maintained for demonstration purposes by the Columbia School of mines, Mine Hill is of especial interest, not only because of its iron deposit is a fine example of an ore vein along a fault, but also for the many large and perfect pyrite crystals and other minerals in small crystals which can be found here.
At 10 m. is the Transylvania Crossroads....At Transylvania is the junction of State 172...
