Wilton Mining Camp, in Knox County, Kentucky, as seen from the southwestern end of the camp lake, taken during the 1920s. Coal mining was slow to develop in Eastern Kentucky, until World War I. During the war, and just after the war's completion, coal mining took off at a startling pace. (Photo courtesy of Richard V. Smith, 120 W. Charles Street, Batavia, OH 45103)
