Henry Clay Furnace
Standing 30 feet high, this pyramid-like structure was used for iron-smelting. It was built in the 1830s and was known to produce four tons of pig iron a day. Owned by the Tassie and Bissell Corporation, it employed over 200 people - no small thing in 19th century rural West Virginia. To get there you'll have to hike a bit. First, drive on County Rd 73/12 from I-68. Turn left on Cooper Rock State Park Rd. which will take you to the Clay Furnace Trailhead parking lot. The hike is about one mile.
