Clifford Eight was a mining town located about a mile north of the community of Colp in Williamson County. The mine first brought up coal in 1905. At its peak, there were over two thousand residents. The community had a large school around the time of World War I. In 1923, the mine closed. During the 1930s, the company sold off the houses. Residents moved away. Today, all that remains is the mine pond, the foundations of the company store and evidence of the old railroad right of way.
