Things To Do



The Piedmont Charcoal Kilns State Site was established to commemorate the kilns built by Moses Byrne in 1869 to supply charcoal for the iron smelting industry in Utah. These conical limestone kilns are huge and measure 30-feet across and 30-feet high. Out of 40 original kils, only three remain for the public to view. It was estimated that during 1873, the kilns could produce 100,000 bushels of charcoal. Wood burned in the kilns came from the nearby Uinta Mountains. The ghost of Piedmont is nearby, as is the Byrne family cemetery. The crumbling remains of a railroad station also stand nearby the kilns. Once, Piedmont was a bustling town, and the limestone kilns produced charcoal for shipment to the mining smelters in Utah. Now, all that remains is a ghost town full of structural ruins. Visitors can travel to the kilns down a county road that runs along the grade of the old Union Pacific Railroad. Be sure to have your camera ready to photograph these unique structures along with the ghost town of Piedmont. Visitors can also visit the nearby Fort Bridger.
