High Quality Content by WIKIPEDIA articles! The Walker Charcoal Kiln is a structure in the Prescott National Forest near the ghost town of Walker, Arizona. It is listed on the National Register of Historic Places. A sign posted near the kiln reads, "This kiln was constructed around 1880 by Jake and Joe Carmichael to convert oak wood into charcoal for use at nearby smelters. The surrounding forest was cut so heavily for charcoal and mine props in the late 1800's that it is just now becoming productive again."
