The kilns were built by Moses Byrne around 1869 near the Piedmont Station along the Union Pacific Railroad.

A granite marker reads: Charcoal Kilns were built by Moses Byrne, 1869, to supply the pioneer smelters in the Utah Valley.

A builder, Byrne had built a number of Pony Express stations and stables.

Most of Byrne's charcoal was shipped to the area around Salt Lake City (the Utah Valley) for use in small smelters and blacksmith shops.

[1][2] The Piedmont Charcoal Kilns were listed on the National Register of Historic Places in 1971.
