Walker Charcoal Kiln, Historic kiln in Prescott National Forest, Arizona.

Walker Charcoal Kiln is an industrial furnace built from granite blocks that stands about 25 feet (7.6 m) tall with carefully positioned openings to regulate air circulation during charcoal production. The design reflects straightforward engineering where each feature served the practical goal of converting wood into charcoal efficiently.

Built in 1880 by Jake and Joe Carmichael, the kiln produced charcoal from oak wood to fuel the nearby silver mining smelting operations. This facility formed a crucial link in the supply chain that supported the region's mining industry.

A sign posted at the kiln records that it was built around 1880 by Jake and Joe Carmichael to turn oak wood into charcoal for nearby smelters. The same sign notes that the surrounding forest was cut so heavily for charcoal and mine props in the late 1800s that it is only now becoming productive again.

The kiln sits within Prescott National Forest and is reached via a short walking trail of roughly a quarter-mile. Interpretive signs at the site explain the charcoal-making process and the structure's role in the region's past.
