Newlees Iron Furnace - Cumberland Gap National Park - Virginia

Historic Newlee's Iron Furnace, located in Cumberland Gap National Park, was constructed in 1819 of locally sourced sandstone blocks, and its interior (seen here) was lined with fired bricks. Each day 625 bushels of charcoal (approximately 52 trees), 6 1/4 tons of locally mined iron ore, and 1,563 pounds of limestone were used to produce approximately 3 tons of iron. The produced iron was used both locally, and shipped as ingots down the Powell River to Chattanooga, Tennessee. Cumberland Gap National Park is located in Appalachian Mountains.
