Lost World Caverns is a National Natural Landmark located in the Greenbrier Valley of West Virginia, featuring a subterranean room approximately 1,000 feet long and 300 feet wide. The cave system is formed in limestone and is renowned for the 'War Club,' a massive 28-ton stalactite formation. Visitors follow a self-guided concrete pathway that descends 120 feet below the surface. The cavern maintains a constant internal temperature of approximately 52 degrees Fahrenheit year-round. It features extensive displays of flowstone, stalactites, and stalagmites, some of which are illuminated for educational viewing. In addition to the caverns, the site includes a natural history museum containing prehistoric fossils discovered within the cave system. The cavern was first explored in 1942 by Virgil C. Arbogast and others. It remains one of the most significant karst systems open to the public in the eastern United States.
