Clinton Furnace stood one mile east, with a stone stack 10 feet across inside and about 35 feet high, built in 1832 by George, William Thomas H., and Hugh A. Poage. In 270 days of 1838 it used 2,992 tons of ore and 247,000 bushels of charcoal to make 950 tons of iron. In 1857 it produced 1,500 tons, and operations ceased before 1867. Kentucky had been a major iron producer since 1791, ranking third in the U.S. in the 1830s and eleventh in 1965. Charcoal timber, native ore, and limestone supplied numerous furnaces in the Hanging Rock, Red River, Between Rivers, Rolling Fork, and Green River regions, where pig iron, utensils, and munitions were made. The old charcoal furnace era ended with depletion of ore and timber and the growth of railroads.
