Warren C. King originally owned and operated the original 16 charcoal kilns that produced charcoal for the two massive blast furnaces of the Nicholia Smelter in upper Birch Creek.

The Warren King Charcoal Kilns are representative of a transitional stage in the technology of charcoal manufacture, between traditional charcoal pits and wood distillation plants. Their technology was uniquely adapted to the needs of the nineteenth-century mining industry of the western U.S. The kilns are also associated with, and representative of, a transformation of that industry, from one based on rich precious-metal placers and lodes to one based on the extraction and efficient treatment of large volumes of base-metal ores. The kilns were listed in the National Register of Historic Places in 1972.
