What people know today as the Piedmont Charcoal Kilns is just a tiny remnant of what used to be an expansive charcoal-making industry in Wyoming. It was constructed in 1869. The kilns were made of local sandstone. They measure around 30 feet in circumference, 30 feet in height, with matching 24 inch walls.

The original charcoal making site used to have 40 kilns. It produced up to 100,000 bushels in its heyday, most of which went to the smelters of Utah Valley.

The Piedmont Charcoal Kilns was actually built by a notable man, Moses Byrne. He was a Mormon and a builder. He took part in establishing a couple of Pony Express stations in the area. Today, the kilns are listed in the National Register of Historic Places.
