March 28, 2017

When you visit the Piedmont Charcoal Kilns you are standing on the edge of the Ghost Town of Piedmont. Piedmont used to be a railroad town with homes, hotels, shops, saloons, post office, and a school. The Piedmont Charcoal Kilns were used to turn wood from the Uinta Mountains into charcoal to be shipped by train usually to Utah. The smell of charcoal is still noticeable when you walk into the kilns.

The Piedmont Charcoal Kilns were built by Moses Byrne in 1869 to supply charcoal for the iron smelting industry in Utah. These conical limestone kilns measure 30 feet across and 30 feet high. Only three and a half of the original four kilns remain.

Wood burned in the kilns came from the nearby Uinta Mountains. It was estimated that during 1873 the kilns could produce 100,000 bushels of charcoal. Most of the charcoal was sent to Utah on the UP railroad.
