Mammoth Spring, the 10th largest spring in the world, and a National Natural Landmark, flows nine million gallons of water each hour. Following the Civil War, this immense water source attracted industrialists who built a gristmill, and later, a dam here. Next, the investors opened large roller mills and a shoe factory. Soon after, the railroad arrived. Still standing near the spring is the charming 1886 Frisco Depot. At the dam, you can walk through the 1925 power plant that brought electricity to the region long before most other rural areas.

Cornwall Furnace is a unique survivor of the early American iron industry. Originally built by Peter Grubb in 1742, the furnace underwent extensive renovations in 1856–57 under its subsequent owners, the Coleman family, and closed in 1883. It is this mid-19th-century ironmaking complex which survives today. At Cornwall, furnace, blast equipment, and related buildings still stand as they did over a century ago. Here visitors can explore the rambling Gothic Revival buildings where cannons, stoves, and pig iron were cast, and where men labored day and night to satisfy the furnace's appetite for charcoal, limestone, and iron ore.
