Alum Cave Trail

Alum Cave was first referenced in a land grant application by three North Carolina farmers in 1837. The resulting Epsom Salts Manufacturing Company mined alum, Epsom salt, saltpeter, magnesia, and copperas in the area until the salts were depleted in the mid 1840s. Today, it is part of the Great Smoky Mountains National Park and a popular destination along the Alum Cave Trail.
